Answer:
They transfer some of their thermal energy
Adaptive genes are selected and passed from generation to generation.
<h3>Natural selection and the evolution of long necks in giraffes</h3>
According to Darwin's theory of natural selection, natural selection selects for adaptive genes in organisms and deselects non-adaptive genes.
Thus, adaptive genes are passed from generation to generation.
In the case of the giraffes. It is plausible that their ancestors kept on stretching their necks in order to feed as the trees they fed on kept growing taller. The taller the tree grows, the longer the ancestors of giraffes stretched their necks to reach it. Otherwise, they just might have to die of starvation.
This adaptation activated the long-neck genes in the ancestors of giraffes. Natural selection selects this trait and it was passed down across generations.

Answer:
c
Explanation:
cuz ya the acidity increases so the ph will DECREASE
<h2>
Answer:</h2>
Option C) The organism can move around its environment using a flagellum.
<h2>
Explanation:</h2>
Out of four options option C) matches the most.
- Although most of the bacteria are Heterotrophs but a variety of species of them are Autotrophs making their own food. Hence option a) is incorrect.
- Bacteria belong to prokaryotes which means they do not have a well defined membrane bound nucleus. hence option b) is also incorrect.
- Most of the bacteria can move through flagella only a few species do not have flagella. Hence this option matches the most.
- Bacteria are unicellular organism and none of the species of bacteria is multicellular. Hence option d) is incorrect.
Resut: Option C) matches the most for defining bacteria.
