Sergeeva-Olga [200]
The answer is letter C. |
<span>
Slight differences in the color of feathers in birds are the result of mutations. Mutation is process that occurs through a long period of time. It is a process in which the genes’ structures changes thus altering the physical characteristics and behaviors of species. This results into variant forms that may be transmitted to the next generations of species. Mutation is caused by an alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of the genes or chromosomes. </span>

photosynthesis and cellular respiration both use electron transport chains. what is the source of electrons for photosynthesis a
goldfiish [28.3K]

Water serves as an electron source in the electron transport process of photosynthesis. The electron is extracted from water by using solar energy.

What is the electron transport chain's source of energy?

The electron transport chain uses the energy released by oxygen and reduced compound reactions such as cytochrome c and (indirectly) NADH and FADH2 to pump protons into the intermembranous space, producing the electrochemical gradient over the inner mitochondrial membrane.

In photosynthesis, water is split to produce electrons in the presence of sunlight, a process known as the photolysis of water. The electrons are finally transferred to NADP+ by the chloroplast electron transport chain, where they are reduced to NADPH.

Therefore, In aerobic respiration, electrons from NADH and FADH2 are transferred to oxygen by the mitochondrial electron transport chain to reduce oxygen in the water.

Why is a cell considered the basic unit of life?
vekshin1

Answer:

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That's because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as a clear boundary between the cell's internal and external environments.

pentagon [3]

Answer:

Null hypothesis: male and female spiders organized in mating pairs don't differ significantly in respect to body length

Alternative hypothesis: male and female spiders organized in mating pairs exhibit significant differences in respect to body length

The application of one statistical test in order to obtain one p-value (probability value) may provide useful evidence to support the alternative hypothesis (or reject it).  

The inference procedure uses the information collected from the sample in order to obtain one conclusion.  Frequentism is a type of inference procedure that can be used to test a hypothetical test case, which is here represented by male and female spiders organized in mating pairs.
