Which statement best describes a cause and its effect that occurs during the process of muscle contraction?
Answer:
Muscle contraction can be explained by sliding filament theory.
1. Activation of muscles: the motor nerve generates an impulse to transfer signals from neurons to neuromuscular junction. This stimulates sarcoplasmic reticulum to release calcium into the muscle cells.
2.Contraction of muscles: calcium in the muscle cells binds with troponin causes actin and myosin to bind. Actin and myosin in the muscle binds and contract by utilizing ATP as a source of energy.
The rate of consumption of nonrenewable resources is more easily changed than the rate of replacement. Question 5 options: True False

Imagine that a newly discovered species of fish normally has three eyes (E), but the rare mutation (ee) causes "diopthalmic" fish with two eyes to be born. In addition, eye color in these fish is inherited similarly to humans, with black eyes (B) being dominant to blue (bb). Assuming these two genes are carried on separate chromosomes, what must the genotypes of two black-eyed, three-eyed parents be if they have a blue-eyed, diopthalmic son
Answer:
Heterozygous with BbEe and BbEe
Explanation:
The genotypes of the two parents must be heterozygous.
From the illustration, E codes for three eyes while ee causes diopthalmic. B causes black eye while bb codes for blue eye.
Black eye genotypes could be BB or Bb.
Three eye genotype could be EE or ee.
A black eyed, three-eyed couple produced blue-eyed (bb), diopthalmic son (ee). From the law of inheritance, the son inheritance the alleles for each trait from the two parents, one from each. Hence, it means that each of the parent posses recessive alleles in their genotypes, that is they are heterozygous for the two traits.
BbEe x BbEe
9 BBEE black-eyed, three-eyed
3 B_ee Black-eyed, diopthalmic
3 bbEe Blue-eyed, three-eyed
1 bbee blue-eyed, diopthalmic
A bird is flying over a field. What will most likely happen if a toxin causes the
hydrogen ion pump to stop moving H+ ions outside the mitochondrial
membranes of the bird's cells?
A. The bird will fly a long distance because it will rely on energy from
glycolysis.
B. The bird will stop flying because it will quickly use up its remaining
energy.
C. The bird will fly only short distances because it will need to rest.
D. The bird will eat more food to build up its energy reserves in the
Krebs cycle.
SUBMIT
Answer:
B. The bird will stop flying because it will quickly use up its remaining
energy.
Explanation:
This is because the mitochondria is known as the power house of cells. Oxidative phosphorylation takes place in this organelle and it involves the conversion of ADP to ATP through the hydrogen ions(protons).
When the hydrogen ion channel is blocked, energy production in cells stop.
This is why the bird will stop flying as it would have used up its remaining energy and won’t have a new one to use to continue flying.

Resistance is a force that Resistance is a force that is always higher than blood pressure. never changes in a blood vessel. acts with pressure to move blood along a vessel. decreases blood flow. increases blood flow.
Answer:
decreases blood flow.
Explanation:
I'll assume the question is about one of the effect of blood flow resistance.
Resistance forces are those forces that opposes the flow of blood through the blood vessels. Resistance forces in the blood vessels changes with the diameter of the blood vessels, and always acts against pressure to move the blood against the blood vessels. If the resistance forces in the blood becomes equal or greater than the blood pressure, there will be no blood flow through the blood vessels. So generally, resistance forces in the blood vessels acts to decrease blood flow through the blood vessels.

Gene expression patterns can be used to test hypotheses based on morphology. For example, the regulatory gene Bapx1 is expressed in the hinge of the developing lower jaw in fishes and reptiles. Where would you predict Bapx1 expression to occur in mammals?
A. in the developing cheekbone
B. in the developing lower jaw
C. in the mature lower jaw
D. in the developing ear bones
Answer:
The correct answer is option D. "in the developing ear bones".
Explanation:
The developing lower jaw of fishes and reptiles has a variety of bones that are joined together, forming the mandible that they use to eat their preys. Some bones in the developing lower jaw of fishes and reptiles are equivalent to the developing ear bones of mammals. Therefore we can predict that the Bapx1 expression in mammals will occur in the developing ear bones. About this evolutionary relationship, scientist Zhe-Xi Luo of the Carnegie Museum of Natural History in Pittsburgh states "Reptiles have [a] jaw full of ear bones from mammals and mammals have an ear full of jawbones of reptiles".
A researcher interested in the disappearance of fallen leaves in a deciduous forest carried out a field experiment that lasted nearly a year. She collected all the leaves from 100 plots scattered throughout the forest. She measured the amount of leaves present in November, May and August. The percentages reflect the number of leaves found, using the November values as 100 percent.
Answer:
Elm: 50 %; 1 %
Hazel: 69 %; 4 %
Explanation:
Assume the table looked like this.
[tex]\begin{array}{crrr}\textbf{Month} & \textbf{Ash} & \textbf{Elm} &\textbf{Hazel}\\\text{Nov} &\text{4271 g}& \text{3481 g} & \text{1723 g}\\ & 100\, \% & 100\, \%&100\, \%\\\text{May} & \text{2431 g} & \text{1739 g} & \text{501 g}\\& 100\, \% & x \, \% &z \, \%\\ \text{Aug} & \text{1376 g} &\text{35 g} & \text{62 g}\\& 100\, \% & y \, \% & w \, \%\\\end{array}[/tex]
To get the percentages for each species for May and August, you divide that month's mass by the November mass and multiply by 100.
[tex]x = \dfrac{\text{1739 g}}{\text{3481 g}} \times 100 \, \% =50 \,\%\\\\y = \dfrac{\text{35 g}}{\text{3481 g}} \times 100 \, \% = 1 \,\%\\\\z = \dfrac{\text{501 g}}{\text{1723 g}} \times 100 \, \% = 69 \,\%\\\\w = \dfrac{\text{62 g}}{\text{1723 g}} \times 100 \, \% = 4 \,\%\\\\[/tex]
The figure below shows the graphs for ash and elm.

A new species of aquatic chordate is discovered that resembles an ancient form. It has the following characteristics: external armor of bony plates, paired lateral fins, and a bony skeleton. In addition to these, it will probably have which of the following characteristics?
a) legs
b) metamorphosis
c) an amniotic egg
d) no jaws
Answer:
a) legs
Explanation:
Based on these characteristics it can also be said that this species would have legs. This is due to this new species having paired lateral fins. That is because paired lateral fins refer to the pectoral and ventral fins, which are corresponding to the fore and hind legs of the higher animals. Meaning that this new species would have had to have legs if they had paired lateral fins, and a bony skeleton would help corroborate this finding.
Answer:
no jaws

Unequal reproductive success ______.Group of answer choicescan lead to a population being less well adapted to its environmentcan lead to natural selectionalways decreases the size of a populationdoes not affect the frequency of expression of traits in succeeding generations of a populationincreases variation
Answer:
can lead to natural selection
Explanation:
Unequal reproductive success _can lead to natural selection_____.This is because if there is unequal reproductive success then one of the organisms is better suited for reproducing, surviving, and passing down their genes to their offspring rather than the organism who is unfit. This is where natural selection comes into play because natural selection is process where individuals better suited for their environment produce more and have better survivality.
So overtime, the organism which is weaker (in sense of fitness) (here fitness relates to reproduction and survival), will not pass as many genes and won't survive, whereas, individual better suited will, hence in a way "Nature selected" the better fit organism.

In the study of cancer, researchers have used different types of cells, different environmental conditions, and different experimental designs. But, all researchers have arrived at the same conclusion. What does this say about the conclusion? It is well supported. It is weakly supported. It is inconclusive. It is refuted.
Answer:
It is weakly supported.
Explanation:
All the factors in each experiment are different. There are not any controls to ensure the results are reliable. When all the factors vary, it cannot be determined whether the factor being tested was the cause of the result, or another factor was the cause. Although all the reasearchers reached the same conclusion, it cannot be proven whether it was caused by the specific factor being tested, or if it was merely a coincidence.
During multiple experiment, if the results are the same or indicate the same conclusion then the reliability of the conclusion increases. Thus option A is correct.
What is the conclusion?The conclusion is the sum of all the observations during our experiment that gives the outcome of our investigation.
During cancer research on the different types of cells, conditions, and different experimental designs end up with the same conclusion which makes it more reliable. So option A is correct.

What happens when T2 phages are grown with radioactive phosphorous? A: Their DNA becomes radioactive. B: Their proteins become radioactive. C: Their DNA is found to be of medium density in a centrifuge tube. D: They are no longer able to transform bacterial cells. E: They transfer their radioactivity to E. coli chromosomes during infection.
Answer: A: Their DNA becomes radioactive.
Explanation:
T2 phage is a virus, it infect and kill Escherichia Coli (E.Coli) which is a bacteria, t2 phage has a DNA that is double stranded while Radioactive phosphorus is an Isotope of phosphorus having same atomic number but different mass number.
Deoxyribonucliec acid(DNA) contains the genetic makeup of an organism.
it double stranded and it is made up of a nitrogenous base, phosphate group and a 5 carbon sugar. When t2 phage grows with radioactive phosphorus in, it becomes infused into the cell and replicated in the virus cell during DNA replication process making it have more copies in the cell this makes the DNA of the t2 phage radioactive in nature.
