<span>The key points about cell theory are as follows:
1. All living organisms are made up of cells; the organisms may be unicellular or multi cellular.
2. The cell is the basic unit of life.
3. New cells are derived from pre-existing cells.
4. All cells maintain homeostasis.
Some new facts have been added to these basic facts; the new facts added include the following:
(A). Energy flow occur withing all living cells.
(B). Hereditary information derived from DNA is passed from cell to cell.
(C). All living cells are made up of the same basic chemical compositions.</span>
<span>The mantle is more dense, so it can not B.
Not even A , because the crust sure does contain naturally occurring radioactive material. Heat is also not efficiently transferred to the surface--most ground is cool,
so correct option is none is above that is D
hope it helps</span>
In most situations, the fittest insects most likely to survive as compared to least fit insects because of the healthy body of that organism.
<h3>What is fitness?</h3>
Fitness can be defined as the ability to perform daily activities with endurance, and strength and resistance to disease, fatigue, and stress.
So we can conclude that the fittest insects most likely to survive as compared to least fit insects because of the healthy body of that organism.

Answer:
Cells vary greatly in shape These shapes are often related to the function they perform. like the disk shape of erythrocytes can absorb and transport oxygen due to increased surface area., the amoeboid shape of leukocytes allow them to squeeze through capillaries. etc.
Explanation:
Cells can be disc-like , polygonal, rectangular, cubopid thread like branched or even irregular. these are related to the functions that each cell performs.
Some examples showing relation between cell shape and function are as follows.:
- Human blood cells are circular and biconcave to transport oxygen.
- White blood cell are amoeboid to squeeze through thin capillaries.
- Nerve cells are long so that they can carry nerve impulse to a long distance very quickly.
- Guard cells of stomata are bean or dumbell shaped to open and close the stomata.
Answer:
id say A:
The model shows that the fetus becomes more complex during development. This is because mitosis allows the cells that make up the fetus to become specialized.
or D:
The model shows that the fetus gets larger as time goes on. This is because mitosis constantly increases the number of cells that make up the fetus.
Explanation:
