Answer:
constant = changes and control is used as the basis of comparison
Explanation:
Constant variables are variables that do not change
e.g such as the temperature ( if it's meant to be kept at a constant temp).
Control variables are meant to be kept constant to allow for a comparison and thus determine the effect of IV (independant variable) and DV ( dependant variable)
Answer:
Wind ward side
Explanation:
The mountain is made up of rocks which supports little amount of plant life.The wind ward side is most suitable for the growth of plant life due to the area being associated with majority of the wind. This wind movement causes an increase in atmospheric humidity and precipitation in the atmosphere which falls on the wind ward side of the mountain. The water and humidity encourages the growth of plant life.
If cellular respiration does not occur, then the level of oxygen present in the cell will get decreased as a result cell can die due to lack of oxygen. This is because<span> cellular respiration provides the energy necessary for cellular activities. Hope this answers the question. Hope this answers the question.</span>
Well...to answer and explain this answer to,you got to think on the simple possibilities. Let's look at the answer natural selection. As you may know,natural selection is the survival of the strongest(or fittest). Nature is picking the best of alleles for the gene pool. Ex. Humans who can survive the harshest of weather or diseases will be chosen to reproduce and keep the genes going.

<h2>Option C is correct</h2>
Explanation:
Natural selection in an aquatic environment resulted in significant changes to whale forelimb anatomy
- Natural selection is the concept of evolution where organisms with favorable traits are selected(by nature) and reproduced and this process allows the organisms to adapt to the changing environmental conditions
- The upper forelimbs of humans and bats have fairly similar skeletal structures which means that they might share a common ancestor in skeletal structure but are functionally different which means they share a homology with each other
- The evolution of limbs of whales is also a part of forelimb adaptive evolution
- Gene mutation rates of higher animals are pretty much similar
- Whales are proper mammals and form a connecting link between fish and mammals
