Answer:the idea that species change over time, give rise to new species, and share a common ancestor.
Explanation:
to better cope with environment
Natural selection gave Darwin the idea for theory of evolution where organisms produce more offspring which able to survive in their environment.
What is natural selection?Natural selection is an evolutionary mechanism. Lifeforms that are better adapted to their surroundings are more likely to flourish and pass on the genes that helped them thrive. Species alter and deviates as a result of this process.
Natural selection, Darwin proposed, is a mechanism for evolution in which heritable traits that help support life reproduce and survive become more prevalent in a population over time.
Darwin and a scholarly colleague, Alfred Russel Wallace, posited that evolution occurs as a result of a phenomenon known as natural selection. According to natural selection theory, organisms generate more offspring than can survive in their environment.
Thus, the answer is natural selection.

Jenna began making a model to show the processes which resulted in the formation of oceans. Art shows three boxes connected with arrows. The label on the first box is 'Water fills the basins', second box is 'Segments of Earth's crust move',and the third box is labeled with a question mark. Which of the following would be the next step in the process? Crust is broken down Earth’s crust moves Earth’s plates meet Sea floor spreading
Answer:
Crust is broken down
Explanation:
In the formation os oceans, at first water fills the basins, in the second step segments of Earth's crust move and in the third step crust is broken down.
In the oceans when water fills the basin, it allows the Earth's crust to move which makes it folded or break apart. When the crust is broken down along with deep cracks, it is filled with water from streams and rainfall flowing in the ocean.
Hence, the correct option is "Crust is broken down".
Answer:
Earth's plates meet
Explanation: After Earth's crust formed, and water filled the basins, giant segments of the crust began to move. These segments are known as lithospheric plates or tectonic plates. The plates float on Earth's molten interior like rafts of rock. The plates move around, driven by convection currents from the Earth's mantle. The plates move over and under and past each other. Where the plates meet, Earth's crust is constantly formed and re-formed.

Is the escape of a rattlesnake from a zoo exhibit an example of an invasive species?
Answer:
No, it isn't
Explanation:
An invasive species is characterized by an organism's appearance in an area it is not a native of, with a high capacity of reproduction that will cause it to be a threat to native species in that area. A species of organism is tagged "invasive" if it is foreign to a region/location and possess a high reproductive rate that spreads fast and causes harm to other species.
Based on the analogy given in this question about the escape of a rattlesnake from a zoo, it cannot be ascertained that it is an example of invasive species. This is because rattlesnakes may be native to that area and possess a zero threat level to the environment in terms of high spreading rate.

Cereals and legumes are complementary in the diet because Group of answer choices Cereals counteract the antinutritional factors in legumes A diet combining legumes and cereals will have a good balance of essential amino acids Cereals are high in lysine Legumes are high in cysteine and methionine
Answer:
A diet combining legumes and cereals will have a good balance of essential amino acids
Explanation:
Cereals are grains that are rich in vitamins, carbohydrates, protein and other essential nutrients, they include wheat, rice, sorghum etc. Legumes include a wide range of seeds, fruits, nuts, vegetables that are rich in proteins, carbohydrates and other nutrients, examples include peas, beans, lentils etc.
Cereals and legumes are referred to as staple foods, they are usually used to complement each other because combining them will result in a good balance of essential amino acids. In cereals, lysine is a limiting amino acid but is usually in high amounts in legumes. However, in legumes cysteine, trypthophan and methionine are the limiting amino acids but are found in cereals. Therefore, this makes legumes and cereals complementary in the diet as it significantly increases the protein quality of the diet.
Certain genetically modified strains of maize produce a powerful natural insecticide. The insecticide occurs throughout the plant, including its pollen. Maize pollen is dispersed by the wind and frequently blows onto milkweed plants that grow near maize fields. Caterpillars of monarch butterflies feed exclusively on milkweed leaves. When these caterpillars are fed milkweed leaves dusted with pollen from modified maize plants, they die. Therefore, by using genetically modified maize, farmers put monarch butterflies at risk. Which of the following would it be most useful to determine in order to evaluate the argument?
A. Whether the natural insecticide is as effective against maize-eating insects as commercial insecticides typically used on maize are
B. Whether the pollen of genetically modified maize contains as much insecticide as other parts of these plants
C. Whether monarch butterfly caterpillars are actively feeding during the part of the growing season when maize is releasing pollen
D. Whether insects that feed on genetically modified maize plants are likely to be killed by insecticide from the plant's pollen
E. Whether any maize-eating insects compete with monarch caterpillars for the leaves of milkweed plants growing near maize fields
Answer:
The correct answer is:
Whether any maize-eating insects compete with monarch caterpillars for the leaves of milkweed plants growing near maize fields (E)
Explanation:
Since the argument has to do with the elimination of caterpillars of monarch butterflies by the insecticidal property genetically modified strains of maize, in order for the argument to hold valid, every other factor that could result in similar effect of the death of carterpillars of monarch butterflies has to be ruled out. one such factor is competition; when another species struggle for limited available nutrition with the carterpillers which can result in their death, and can easily be confused as the effect of the insecticidal property of the modified maize strain.

The frequency of spear grasses in different locations of an abandoned field is 40 After throwing a quadrant 80 times. Calculate its population size using a quadrant dimension of 1 square meter.
Answer:
40
Explanation:
The population size refers to the total number of individuals in a population. It can be obtained by counting the total number of individuals in a population. In a typical plant field where it is almost impossible to count the number of individuals, the population size can be mathematically estimated using the quadrat method:
Population size = (A/a) x n,
where A = area of the field, a = area of quadrat, and n = number of plants per quadrat.
In the illustration, the area of the abandoned field was not given. Hence, it is assumed that the area of the field is equivalent to the number of quadrat thrown. Since the size of the quadrat is 1 square meter:
Area of the field = 80 x 1 = 80 square meters.
Number of plant per quadrat = 40/80 = 0.5
Population size = 80/1 x 0.5 = 40
Therefore, the population size is 40 spear grasses.

A forensic scientist is trying to find out the number of adenine bases in the DNA sample that he obtained from a crime scene. What can he assume about the number of adenine? The number of adenine bases will be equal to the number of guanine bases. The number of adenine bases will be equal to the total of all the other bases. The number of adenine bases will be equal to the number of thymine bases. The number of adenine bases will be half of the number of cytosine bases.
Answer:
The correct option is;
The number of adenine bases will be equal to the number of thymine bases
Explanation:
The four chemical bases that make up the DNA code are adenine (A), guanine (G), thymine (T), and cytosine (C) which are arranged based on a specif organism such that they represent the information regarding the building of the organism
The chemical bases of the DNA are found in pairs consisting of two chemical bases which are then known as base pairs. The possible base pairs are;
Adenine (A) pairing with thymine (T)
Cytosine (C) pairing with Guanine (G)
Therefore, the forensic scientist should expect to find that the number of adenine bases will be equal to the number of thymine bases.
Since the scientist was trying to find out the number of adenine bases in the DNA sample, assumption that the number of adenine would be equal to the number thymine would help.
According to the base-pairing rule of Chargaff, adenine always pairs with thymine while guanine always pairs with cytosine.
Going by this rule, we can say that the number of adenine must be equal to the number of thymine while the number of guanine must be equal to the number of cytosine in any DNA.

You are working on a legal case for the Environmental Protection Agency that is
suing a logging company for using unsustainable logging practices and
endangering the environment. In order to avoid paying heavy fines to the
government, the logging company can institute safer practices but they do not
know any. What can you suggest to them?
Answer:
Explanation:
The logging company should go by the rule governing the forest and seek for government permission before cutting down any tree. There are due processes that allows you cut some forest timbers after establishing a new one but this is done with the consent of the government and the agreement that is made between the company and the government. An agreement will be reached on how the cutting can be done to avoid total loss of our forest and areas that can be used.
Going through the right channel before cutting forest trees will help reduce the amount of fines they pay almost all the time they are caught from illegal cutting.

The reflex arc is the sequence of events since a stimulus reaches the body, until the body reacts to it. The correct order is a, b, d, e, c.
What is the reflex arc?The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts to it.
In general terms,
A stimulus of varying nature reaches the body. The peripheric nervous system -PNS- receives the stimulus and sends this information to the central nervous system -CNS-. The CNS processes the information and sends another signal as a response to the stimulus.This mechanism is known as the reflex arc.
Five elements compose the reflex arc, which are receptors, three types of neurons, and effectors.
There are three types of neurons involved in the mechanism:
• Afferent or sensorial neurons
• Interneurons
• Efferent or motor neurons
Action:
Ascending branch1) The stimulus reaches the body and is received by the specialized sensory receptors.
2) Information is received by these receptors and converted from stimuli energy (temperature, pressure, light, etc.) to action potential energy.
3) Afferent neurons, placed in the dermis and epidermis, receive information from receptors, react and send the information to the central nervous system as nerve impulses.
Descending branch4) Once the information reaches the central nervous system, it is processed by the interneurons that analyze it before sending a response.
5) Interneurons manage many sensorial signals, evaluate and compare them, and send a motor response.
6) Efferent neurons receive information from the interneurons and are stimulated to carry these new signals from the central nervous system to the cells of the effector organs. The effector organ can be a muscle or a gland.
7) Finally, the target tissue responds to the stimulus as a contraction, if it is a muscle, or as hormones release if it is a gland.
In the exposed example, the corrcet order is
a- A receptor detects a signal.
b- A sensory neuron sends a signal to the spinal cord.
d- A relay neuron sends a signal to a motor neuron.
e- A muscle receives a signal to contract.
c- A bone moves.

Which statement regarding serum magnesium (Mg ++) is true?
A) Alcohol-related diseases frequently cause low Mg+ levels.
B) Vomiting is not generally seen as a major cause of Mg+ loss.
C) Mg++ levels present similarly to calcium (Ca++) levels in the blood.
D) Mg+ deficiencies often result in low serum potassium (K+) levels.
E) Mg+ deficiencies must be treated before potassium (K+) deficiencies.
Answer: Option B,C,D and E.
Vomiting is not generally seen as a major cause of Mg+ loss.
C) Mg++ levels present similarly to calcium (Ca++) levels in the blood.
D) Mg+ deficiencies often result in low serum potassium (K+) levels.
Explanation:
Serum magnesium is the test that indicate the level of magnesium in the body. A person can have high serum magnesium or low serum magnesium.. serum magnesium is regulated by the kidney via henle loop.
A damage to the kidney can increase the magnesium level in the blood and cause hypermagnesemia. Renal failure cause magnesium excess and the body will not be able to excrete it.
Magnesium deficiency is similar to potassium deficiency.
A person with low magnesium may also have low calcium and low potassium because magnesium help to transport calcium and magnesium ions in and out of the body cells.
Administration magnesium is essential for correcting the hypokalemia. Magnesium deficiency inhibit and affect Na-K-ATPase, which in turn reduce cellular uptake of K+. A decrease in cellular uptake of K+, when it occurs along with increased urinary or gastrointestinal excretion, would lead to K+ wasting and hypokalemia.
magnesium deficiency exacerbates potassium wasting by increasing distal potassium secretion.
Vomiting is not a general cause of magnesium loss.
Therefore options B, C, D and E are correct
B) Vomiting is not generally seen as a major cause of Mg+ loss.
C) Mg++ levels present similarly to calcium (Ca++) levels in the blood.
D) Mg+ deficiencies often result in low serum potassium (K+) levels.
E) Mg+ deficiencies must be treated before potassium (K+) deficiencies.
After reading the paragraph below, answer the question that follows In the North Pacific Ocean, two groups of the same species of killer whales (Orcinus orca) appear to be forming two different species based on what they eat. One group eats fish and the other eats mammals such as seals. Another difference between the two groups is in how they hunt. Whales that hunt fish tend to travel in large pods (groups of whales) and vocalize often. Whales that hunt seals, however, tend to travel in very small groups and vocalize very little. If these hunting differences brought about speciation, the separation would be considered:____________
Answer:
behavioral separation
Explanation:
The separation leading to the speciation of the two groups of killer whales would be considered a behavioral separation.
Behavioral separation or isolation is a form of separation that occurs between two groups of individuals (that use to be of the same group) as a result of preference for a particular behavior or set of behaviors.
The preference for the behavior eventually leads to the two groups becoming separate species, a form of speciation known as sympatric speciation.

An example of positive feedback loop would be: A. the release of glucagon in response to low blood sugar B. all of the above C. the release of a hormone in response to a single stimulus D. the release of oxytocin in response to stretching of the uterus
D. The release of oxytocin in response to stretching of the uterus.
Explanation:
There are two types of feedback loops, negative and positive.
Negative feedback loops' main goal is to maintain homeostasis, or equilibrium within the body. When there is a stimulus, the negative feedback loop will try to make the output less than it is, to make homeostasis equal again. An example of this would be regulating blood sugar. If your blood sugar levels are low, your body will release glucagon to make them higher, that is a negative feedback loop.
Positive feedback loops' main goal is to make the reactions go by more quickly, it makes the equilibrium unstable while accelerating the reaction. An example of this would be releasing chemicals in the body such as oxytocin, during childbirth to make it less painful and to speed up the process.
