Answer:
Human activity affects the availability of food for deer populations in many ways. Hundreds of years ago, dear were very rare but now more civilization has occurred making more food for dear in the gardens outside of peoples houses. Also, people have started to kill organisms that they found harmful to themselves, causing the dear population not to decrease, but stay the same and reproduce.

A vertebrate-animal embryo gives rise to the centrum. The centrum is a bone that is part of the vertebral column. It is the hollow space within the vertebra that protects and contains the spinal cord. Within this hollow area are several nerves that send impulses to the brain enabling the organism to function and be at its homeostasis.
Answer:
The correct answer is option a.
Explanation:
Yes, the light reactions also depend upon the Calvin cycle. Calvin cycle refers to a phenomenon that is used by the plants and algae to convert carbon dioxide from the atmosphere into sugar, the food needed by the autotrophs in order to grow. The plants rely upon the Calvin cycle for food and energy.
In the given case, the rate of oxygen production would get diminish as the rate of ATP and NADP+ generated by the Calvin cycle diminishes. Of all the outcomes of the Calvin cycle, ADP and NADP+ are the only ones that get utilized by light reactions.
The ADP and NADP+ are used up by the light reactions to fuel their reactions. This illustrates that if the rate of ADP and NADP+ generated by the Calvin cycle diminishes the production of oxygen by the light reactions also diminishes.
Answer: The answer is that the phenotypic ratio among phenotypes produced from an F1 X F1 dihybrid cross is 9:3:3:1.
Explanation:
Independent assortment of genes explains how alleles on different chromosomes arrange independently of one another during gamete formation.
So, a dihybrid cross involving TWO characters (e.g Seed color & seed shape) would have its respective alleles DISTRIBUTED whether dominant or recessive, for crossing to occur and yield varying proportion of offspring in the well spread ratio of 9:3:3:1; making it a consequence of independent assortment of genes
Answer:constriction of pupil
Explanation:the circularly arranged smooth muscle fibers in the highlighted structure ie the iris causes constriction of the pupil.
The iris basically has ciliary muscles that control Lens shape ,this happens when the ciliary muscles under the signal of the parasympathetic nervous system contract leading to the constriction of the pupil and when these muscles relax then dilation of the pupil will occur
