In 1847, the German biologist Christian Bergmann noted that mammals and birds living at higher latitudes (farther from the equator) are on average larger and bulkier than related species found at lower latitudes. Suggest an evolutionary hypothesis to explain this observation.
Answer:
not quite sure how to do the hypothesis but its likely to be something to do with the fact that they need more fat and muscle due to the thinner atmosphere as respiration is harder to occur.

Because the ANS is a visceral motor system, afferent pathways are of no importance
and actually are rarely found.
True
False
Answer:
The correct answer is - false.
Explanation:
The ANS is a system consider as the visceral motor system, however, the afferent pathways are the system that is used to flow the signals to the control center from taking from the receptor and are very essential for the homeostasis communication of the nervous system.
This pathway involves the neurons with the signals to the spinal cord and the brain as sensory data. This pathway is very common to provide communication between the receptor and spinal cord.
Compare and contrast gradualism and punctuated equilibrium. Provide at least one comparison and one difference in your answer. You may use examples for each if that helps you with answering the question.
Answer:
Gradualism and punctuated equilibrium both are the process of evolution of species over time. However, the gradualism process involves the evolution that occurred slowly, occurring in small periodic changes in the gene pool over a long period of time. Whereas Punctuated equilibrium takes place there are longer periods of apparent stasis interrupted by the sudden change.
They both help in finding the relative change in evolution rate and assist in the study of the anatomical changes occurred during the evolution in different kind of animals or organisms.

The reindeer migrate from north to south in the summer months to reach
more fertile feeding grounds. They migrate to the north in winter months.
The reindeer populations migrate to an intermediate location in Norway to
mate and then diverge to the northernmost and southernmost regions to
avoid competition for food.
There are two species of reindeer in Norway. The northernmost species
reproduces in the winter, causing an increase in population size. The
southernmost species reproduces in the summer, causing an increase in
population size.

Two of the answers are correct.
Answer:
vasoconstriction of capillaries.
baroreceptors in the aortic arch.
Explanation:
Vasoconstriction of capillaries and baroreceptors in the aortic arch are the two quick responses of body to maintain normal blood pressure during hemorrhage. Vasoconstriction is very necessary for lowering acute blood loss during hemorrhage means escape of blood from a ruptured blood vessel as well as maintain body heat and arterial pressure. The function of baroreceptors is to respond to the change in the tension of the arterial wall when blood pressure changes.

Which statements regarding the ATP-ADP cycle are true?
ATP synthesis takes place in the mitochondria of eukaryotic cells.
The given question is incomplete as the group of choices are not given, however, the choices are associated with the question is given below:
ATP synthesis takes place in the mitochondria of eukaryotic cells.
ATP is regenerated from ADP through the process of phosphorylation.
energy is stored in the covalent bonds between phosphates, with the greatest amount of energy in the bond between the second and third phosphate groups.
most of the readily available energy stored in ATP is stored during the manufacture of adenosine.
the ribose sugar in the model above is the direct product of photosynthesis.
Answer:
The correct answer is given below:
Explanation:
ATP synthesis takes place in the mitochondria cell organelle in the eukaryotic cells, however, a small part of ATP generation takes place in other cell regions but most of the ATP synthesis is occurs in the inner membrane of mitochondria which makes it energy house of the cell.
ATP is formed by the addition of phosphorus to ADP and this process is called phosphorylation.
Each bond of the adenosine and its three phosphates has stored energy in their covalent bonds. The last two phosphates have a high amount of energy in their bond.

Water is transpired through stomata, but carbon dioxide also must pass through stomata into a leaf for photosynthesis to occur. There is evidence that the level of carbon dioxide in the atmosphere has not always been the same over the history of life on Earth. Explain how the presence of a higher or lower concentration of atmospheric carbon dioxide would impact the evolution of stomata density in plants.
Answer:
Escribir en español, por favor.?
During those high-carbon-dioxide times, plants that produce fewer stomata,
when carbon dioxide levels are low, plants need many stomata in order to scrape enough carbon dioxide to survive.
How does carbon dioxide affect water uptake?Plant water use, an increase in atmospheric CO2 means that stomata, or the pores on leaves that exchange gases between the leaf and the atmosphere, do not need to open.
Thus, carbon dioxide levels are low, need many stomata in order to scrape enough carbon dioxide to survive.

Answer:
Choice C
Oxygen must be diluted because it is a highly combustible gas.
Oxygen must be diluted because it is a highly combustible gas is important for nitrogen to be more abundant in our atmosphere than oxygen.
Why nitrogen is important?Nitrogen is extremely important to living material. Plants, animals and humans could not live without it.
The major source of nitrogen is the atmosphere. It exists as a colorless, odorless, nontoxic gas and makes up about 78 percent of the atmosphere. Nitrogen is also found in the Earth's crust as part of organic matter and humus.
Our atmosphere's nitrogen gas is a molecule made up of two nitrogen atoms. This kind of nitrogen can't be utilized by plants directly. Before it can be utilized by plants, nitrogen needs to be transformed into other forms.
Therefore, Oxygen must be diluted because it is a highly combustible gas is important for nitrogen to be more abundant in our atmosphere than oxygen.
