Answer: B) k
Explanation:
potassium is an intracellular cation.
In resting state its gated channels are shut; so 95% are trapped inside the interstitial fluids of the axoplasm;Although these channels leak for some to escape down the concentration gradient to the extracellular environments of the axon, most of these ion are concentrated inside the interstitial fluid of the axon to maintain RMP
The answer is 23.
A human being receives 23 chromosomes from each parent. So each human has 46 chromosomes. Chromosomes X and Y determines your sex.
Transposable elements and short tandem repeats are different because short tandem repeats make up only a small percentage of a given genome while transposable elements often make up larger parts of a genome. So the correct option is C.
<h3>
What are transposable elements? </h3>
Transposable elements or transposons are a class of genetic elements. They can “jump” from one location to another, in a genome.
Even though they are called “jumping genes,” they have an integrated site in a genome and are maintained there. Also, most of them are eventually inactivated and can not move any longer.
Whereas Short tandem repeats or STRs are short repeats of DNA. They are also known as microsatellites or simple sequence repeats. They have a repetitive unit of 1-6 bp and form a series of 100 nucleotide lengths.
Therefore the correct option C.

i am pretty sure just learned it like 3 yrs ago if not then its the opposite
HI~ I hope this helps
(these answers were hand-written meaning I did not copy and paste so, feel free to use the answers freely)
1.
When ecosystems change rapidly the fundamental environmental cycles such as the circulation of water, carbon and nutrients can change as ecosystems depend on them. The usage of factors such as freshwater, carbon dioxide emissions and fertilizer provides a large benefit to humas therefore meaning, that large and rapid changes to an ecosystem could also effect the things we as humans rely on.
2.
Complex organic matter is broken down by decomposers into carbon dioxide, water etc. The ecosystem is affected based upon the fact that the decomposition of organic matter that is produced by plants, animals and soil organisms is an important process which affects the different important ecosystem processes like nutrient cycling and carbon sequestration.
3. (could have two answers- I recommend the second)
Adaptation- due to the mutation process which results in changes in the structure and function of organisms, these ecosystems would be different as well as unique. The organisms which possesses the traits needed to adapt could then survive as its unique characteristics due to mutation would provide a strong ability
Rise in temperature- If the temperature located on earth was to rise, organisms would have a higher living rate as bacterial life flourishes in warmer temperatures and dies out in colder ones.
4.
~The rapid change of increased food production provides better life sustainability to those living in the ecosystem.
~The rapid change in a large increasing number of organisms could be helpful as they often live of off one another.
5.
~Rapid growth of things such as phytoplankton which cause dead zones are harmful to the ecosystem. Dead zones create zones where too much oxygen is consumed resulting in areas where plants and sea life can no longer survive.
~Whereas the rapid increase of organisms could also be harmful to an ecosystem as the possibility of the organism outnumbering the food sources could become prominent.
