The four factors that affect evolution are mutations, natural selection, genetic drift and the gene flow, In the case, if the ground finches that Grants studied, we can observe the working of the natural selection. Due to change in the conditions in the environment, the large beak was an advantageous trait that was favored by the natural selection. The result of this process was an increase in numbers of large beaked finches and decrease in small-beaked finches compared to the initial numbers in the population.
Answer:
A specific environmental factor that will cause a response to living things will be light from the sun.
Explanation:
An enhanced amount of light from Sun will cause the plants to have enhanced photosynthesis. Photosynthesis can be described as a process by which plants use light energy from the sun to convert carbon dioxide and water into sugar (food) and oxygen.
In animals, enhanced amount of light from the sun will cause sweating and vasodilation.
The process of photosynthesis won't occur in animals and the process of sweating won't occur in plants.
The question is incomplete. The complete question is as follows:
Functions of astrocytes include all of the following, except
A) performing repairs in damaged neural tissue.
B) guiding neuron development.
C) functioning in action potential transmission.
D) maintaining the blood-brain barrier.
E) creating a three-dimensional framework for the CNS.
Answer:
Functioning in action potential transmission.
Explanation:
Astrocytes may be defined as the glial type star shaped cells present in the central nervous system. They envelope the synapse and can function with millions of neuron at a time.
Astrocytes are involved in the structural support in the brain and can repair the damaged and wear nerves tissue. Their main function is acting as blood brain barrier. The action potential transmission is mainly done by neurons and not by the astrocytes cells.
Thus, the correct answer is option (c).
Muscles - they are meat, and animals will eat the meat. They also decompose, leaving no trace of the remains.
Answer:
The second one is correct
Explanation:
A leukocyte is responsible for the immune system
