Answer:
Colonization by plants may provide habitat, facilitating colonization of animal species.
Early colonizing plants may increase the nutrient level of the soil, facilitating the colonization of other plant species.
Animal colonizers may increase pollination of some plant species, facilitating their colonization.
Explanation:
The plants provides habitat as well as food to organisms that helps in the colonization of that organisms because every organism needs food and living place for its survival. Some plants increase the nutrient level in the soil through fixation of nitrogen which leads to the colonization of other plant species in that environment. Some animals causes pollination of plants which helps them in their colonization so all these organisms have a positive impact on the occurrence of other species.

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.

How might green spaces help reduce the negative impact that humans have on Earth’s water supply?
It would give nature a place to fight back, and become more healthy, and less hindered. Cities mess up the evaporation cycle, and because of parks, the water is able to be soaked up by grass, and then released through evaporation. When it rains over a city, the water goes into gutters, and becomes more polluted.

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.

A)
B)
C)
Reindeer migrate from north to south in the winter months to reach more
fertile feeding grounds. They migrate to the north in summer months.
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.

How is the small intestine designed to absorb digested food ?
Answer:
Small intestine is designed to more and more area for absorption of digested food and transfer into the blood for circulation throughout the body. The inner lining of small intestine has a large number of finger-like projections called villi. These villi provide a large surface area for absorption of food.
Explanation:
Hope this helps!
Have a good day or night!
➜ The small intestine is the main region for the absorption of digested food. The inner lining of small intestine has millions of tiny finger-like projections called villi. The presence of villi gives the inner walls of the small intestine a very large surface area for absorption of digested food. The villi are richly supplied with blood vessels which take the absorbed food to each and every cell of the body.

Answer:
independent variable - x , dependent variable - y
Explanation:
the indepent variable is something that is stable , it does not change & the dependent variable is that variable that depends on the independent variable
Design an experiment that would help you collect the data you have identified in question four independent variable - x , dependent variable - y.
What is independent variable?The indepent variable is something that is stable , it does not change & the dependent variable is that variable that depends on the independent variable.
The experimenter's chosen variable or variables are considered independent. The anticipated "cause" will be this manipulation. The independent variable's value determines how much the dependent variable is worth.
The result of the cause will be this (if the manipulation succeeds). One group of volunteers receives a medication, while the other receives a placebo. Cancers diminish in the medication group but they do not in the control (placebo) group.
Therefore, Design an experiment that would help you collect the data you have identified in question four independent variable - x , dependent variable - y.

Very rapid (i.e. in 1-2 seconds) responses to maintain normal blood pressure during a sudden decrease in blood volume by hemorrhage can be initiated by Group of answer choices secretion of ADH from the posterior pituitary. vasoconstriction of capillaries. baroreceptors in the aortic arch. vasodilation of precapillary sphincters. 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.

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.
