C is yur answer stay and nurture
Answer:
A scientific theory refers to the possible explanation of the natural event. It can be tested repeatedly and can be verified by anyone with the help of predefined sets of protocols and scientific experimentation.
Similarly, Darwin proposed the idea of natural selection as the mechanism of evolution.
Various experiments in labs, as well as observations made under natural conditions, proved that natural selection plays a major role in the evolution.
Examples may include industrial melanism of peppered moths, long neck of Giraffe, different shapes and sizes of beaks of Darwin finches et cetera.
This is why natural selection is considered a theory now.
Answer:
It is a fact and not a theory
Explanation:
A scientific theory is some natural phenomenon that has been tried and tested several times and backed by logical and testable observations and hypotheses in a way that in future anyone can test it. It is not a guess or hunch but a concept explained with logic and backed by solid unvarying proofs.
In case of biological evolution, observations have been made and tested several times so that no more further testing or trying is required. Hence, by this logic evolution can be considered as a fact but it can not be considered as a theory.
produces an exact copy of the parent organism
requires the sperm and egg cells
is the same as mitosis
cells! A newly-made cell will grow, but once it reaches a certain size it will divide to form two
new cells rather than growing bigger. Why is this? Why aren't you made of a few dozen, or a
few hundred cells, instead of trillions? Why don't single-celled organisms like amoebas and paramecia grow
as big as a human? In this lab, we will investigate this question using model cells.
Explanation:
new cells rather than growing bigger. Why is this ?
There are two main reasons why cells divide rather than continuing to grow larger and larger: ... If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. Cell Division. Cell division is the process by which cellular material is divided between two new daughter cells.
Why aren't you made of a few dozen, or a
few hundred cells, instead of trillions?
if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.
Why don't single-celled organisms like amoebas and paramecia grow
as big as a human? again The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
i belive this is just the introduction to the project but here
are primarily sugars and starches
are the most readily available source of energy for organisms
are the largest of the four main biological macromolecules
Answer:
are the most readily available source of energy for organisms is the correct answer.
Explanation:
SOS:
The answer is triticum!!!
Hope this helps!!!
