Answer:
The correct answer is option A, when there are unlimited resources
Explanation:
In an exponential growth, the size of population increases with a tremendous rate as there is no competition for resources among the species. A common example of exponential growth can be of bacteria, whose population increases tremendously in unlimited supply of nutrients. The exponential growth can be mathematically represented as
dN/dT=rmaxN
where r max = maximal growth rate for a species
N = population of a species
Answer: Chemical Change
Explanation:
Enzymes like pepsin are found in the stomach and act on food to break it down into simpler substances. This is an example of a —
Chemical change
Answer:
It is by mating.
Explanation:
You know how we all look like our parents. Well it is because some of their traits went from them to us through our DNA. So it makes us get their traits. Same with animals btw.
The limitations of cell size are:
1) Surface area to volume ratio
2) Nucleo cytoplasmic ratio
3) Fragility of cell membrane
What are the cause of limitations on cell size?
The need for a surface area of sufficient area to allow the cells function→.
→If the surface area of cell increase volume increase to the cube of the linear increase.
→ Nuclie contains information needed for protein synthesis . Some cells reduce this limitation to increase the no. Of nucleus called multinucleated.
Examples are muscle cells.
