Fitness in an evolutionary sense is measured in:
a. Number of viable offspring produced
b. Physical appearance
c. Lifespan
d. Ability to survive
Answer:
D. ability to survive
"The central concept of natural selection is the evolutionary fitness of an organism. Fitness is measured by an organism's ability to survive and reproduce, which determines the size of its genetic contribution to the next generation."
Fitness in an evolutionary sense is measured in the ability to survive in a particular habitat. Thus, the correct option is D.
What is Fitness?Fitness may be defined as the situation of survivability of an organism under a given condition.
It is the concept of natural selection that it is only the relative fitness that estimates the existence or extinction of species in a particular habitat.
The Relative fitness of an organism overall depends on relative survival and relative reproduction.
Therefore, Fitness in an evolutionary sense is measured in the ability to survive in a particular habitat. Thus, the correct option is D.

what macromolecules are found in a hot dog ?
Answer:
contain nitrites and/or nitrates
Explanation:
The meat is comprised of beef, pork, or turkey, which are all forms of protein (again, amino acid polymers). There is also a fair amount of fat (animal fat tends to be in the form of triglycerides) and some degraded genetic material from the original organism now being turned into food. :) In addition to these things, the hot dog may contain some food coloring and will likely contain some preservatives - a common preservative for meats (to prevent botulism and rancidity) is sodium nitrite
Do you think people use energy before modern times why or why not
Answer:
Yes
Explanation:
Before the modern times, energy consumption was vital in order to survive. For example, you need heat (thermal energy) to cook food and also be in a decent state of temperature for your body. If they had be never used energy, the generations wouldn't go on. Energy is our main source of living. Solar energy provides sunlight to plants so they can be grown healthily to provide nutritious fruits and vegetables.
To conclude, yes, people did use energy before the modern times otherwise, they would've not survived.
Before the manufacturing revolution, our energy demands were mediocre. For heat, we relied on the sun. Whenever the sun disappointed us, we scorched wood, hay, and withered dung. Our society's energy use changed forever, even with the low-cost automobile and the expanse of electricity. Energy usage increased rapidly, doubling every decade. The price of energy production was decreasing unwaveringly, and the efficient use of energy was not a concern. Drivers lined up at gasoline stations to purchase gas, and President Jimmy Carter went on television to announce that energy preservation was "the moral equivalent of war." New factory orders had already stopped because of multibillion-dollar price overruns, soaring-high inflation, and a slowdown in electricity demand growth due to the early effects of energy preservation. So I think people used energy before modern times.

A football player gets tackled during the game, which of the following body systems is responsible for protecting their organs?
circulatory system
reproductive system
skeletal system
nervous system
Answer:
Skeletal system
Explanation:
the bones of the skeleton protect the internal organs and reduce the risk of injury on impact. For example, the cranium protects the brain, the ribs offer protection to the heart and lungs, the vertebrae protect the spinal cord and the pelvis offers protection to the sensitive reproductive organs.
Answer:
I believe your best choice from the given choices above would be C) skeletal system. The bone structure within the human body, such as the rib cage for instance, provides protection for our organs and takes more impact rather than any of our organs. Without our skeletal system, we would have zero protection for our organs, increasing the chance of more internal body damage.
What is the overall net gain of ATP in cellular respiration per one molecule of glucose? between 0-10 between 10-20 between 30-40 between 40-50
Answer:
C 30-40
Explanation:
The overall net gain of ATP in cellular respiration per one molecule of glucose is - between 30-40 (aerobic respiration)
In aerobic respiration, macromolecules such as glucose break in the presence of oxygen to produce energy. That occurs in mitochondria. The stages of aerobic respiration are glycolysis, the Krebs cycle, and ETS.
Glycolysis is the first stage of cellular respiration that is a metabolic pathway of glucose that takes place in the cytosol. Here, the glucose molecule converts into two molecules of pyruvic acid or pyruvate that forms ATP and NADH as energy.
In glycolysis - six ATP molecules are produced.The citric acid cycle is the second stage where In the citric acid cycle, two molecules of ATP are produced.Oxidative phosphorylation of cellular respiration that produces FADH₂ two and eight NADH molecules that produce ATP.=> Two ATP molecules = one molecule of FADH₂ and, therefore, the number of ATP produced from 2 FADH₂ - 4 ATP.
=> NADH = ATP molecules by each molecule and therefore the number of ATP produced from 8 NADH - 24 ATP.
=> The number of ATP produced from the one glucose molecule under aerobic respiration is given as follows:
From glycolysis = 6 ATP
From citric acid cycle = 2 ATP
From FADH₂ = 4 ATP
From NADH = 24 ATP
total 36 ATPs.
Thus, under aerobic respiration 36 molecules of ATP are produced from one molecule of glucose thus, the correct answer would be - between 30 - 40.

How does the environment influence the survival advantage/disadvantage of certain characteristics?
Answer:
Many students believe that the physical characteristics of organisms change in response to changes in the environment in which the organisms live, and that these changes are passed on to future generations. For example, there is widespread belief that, over many generations, giraffes have gradually developed longer necks as they competed with other animals and each other to reach higher and higher leaves on trees for food.
Many students also believe that organisms can deliberately develop new traits in order to improve their chances of survival. As an example, students believe that moths with spotted wings are able to change the color and patterns on their wings so they are better camouflaged among tree trunks that may have become darker from pollution from industry. Many students also believe that repeated use of insecticides like DDT has meant present populations of insects have become

How many valves does the human heart have?
Answer:
The right auricle opens into the right ventricle, this opening is guarded by the tricuspid valve (having three cusps or flaps). Similarly, the opening between the left auricle and the left ventricle is guarded by the bicuspid valve (having two cusps or flaps). These valves regulate the flow of blood in one direction i.e., from auricles into the ventricles.
The blood flows from the right ventricle into the pulmonary artery and from the left ventricle into the aorta (the largest artery). The flow of blood from the ventricles into these two arteries is also regulated by valves. These valves resemble a half moon, hence they are called semi-lunar valves. These valves are present at the opening where the pulmonary artery and aorta leave the right and left ventricles respectively. They ensure that the blood does not flow back into the ventricles.

Answer:
Explanation:
He determined the amount of charge on an electron
Explanation:
He determined the amount of charge on an electron
The information which Millikan contributed to the understanding of electrons is: D. He determined the amount of charge on an electron.
An atom can be defined as the smallest unit which comprises the matter that forms all chemical elements. Thus, atoms are typically the fundamental building blocks of matter and as such determines (defines) the structure of a chemical element.
Generally, atoms are typically made up of three (3) distinct particles and these are;
Protons.Neutrons.Electrons.Electrons can be defined as the subatomic particles of a chemical element that are negatively charged and as such are having a magnitude of -1.
Robert Andrew Millikan was born on the 22nd of March, 1868 in Illinois, United States of America. He was an experimental physicist who got honored with a Nobel Prize in 1923 for his outstanding work in the field of physics, which included the following;
The study of the photoelectric effect.The measurement of the elementary electronic charge of a single electron.This ultimately implies that, Robert Andrew Millikan using an electric field with a small oil-drop determined the magnitude of an electron's charge.
In conclusion, the information which Millikan contributed to the understanding of electrons is determining the amount of charge on an electron.

Explanation:

You are conducting an experiment to measure the gain in mass of a young mouse over 10 weeks. Instructing a graph represent your data which variable should you place along the X axis and which variable should you played along the Y axis
In this experiment, the gain in mass should be plotted along the Y axis while the time (in weeks) should be plotted along the X axis of the graph.
The easiest pattern of reporting experimental results in science is by the use of a graph. A graph is a diagrammatic representation of the relationship between two variables along the X-Y Cartesian axes.
In this experiment, we are trying to represent the relationship between the gain in mass and time taken. The experiment is scheduled to run over a course of ten weeks.
The X axis ought to represent the time in weeks while the Y axis ought to represent the gain in mass.
This derives from the fact that it is conventional for the dependent variable (in this case gain in mass) to be plotted along the Y axis while the independent variable (time) to be plotted along the X axis.
