Soil, Temperature, and water would be practically the 3 biomes or the aquatic ecosystems. They are both natural and enables you to live successfully. So as for the organism that live there, like plants, the sun supports the plants, also water, and also the soil from the ground. Therefore, those would be the 3.

Part 1:

A solution that causes a cell to swell is a hypotonic solution.

In an isotonic solution, there is no change in the size of the cell.

All three cause osmosis.

A solution that causes a cell to shrink is a hypertonic solution.

Part 2:

1. H. Energy

2.D. Endocytosis

3.G. Diffusion

4.B. Exocytosis

5.E. Facilitated Diffusion

6.A. Osmosis

7.C. Active Transport

8.F. Passive Transport

Sorry. I don't know how to explain part 3 ,but I tried and failed so I deleted it. Part 1 and 2 are correct though.

A recessive allele does not affect the phenotype of a heterozygous person.
Effectus [21]

Answer: A. true

Explanation: The phenotype is the physical characteristics of a person. So, if a person has brown eyes, which may be a characteristic that is dominant, then they would have a genotype of BB or Bb. The reason why Bb, heterozygous, is not a different color is because the recessive b does not affect the dominant B allele.

Hope this helps!!!

An action potential causes the release of neurotransmitters by:________.
seraphim [82]

Answer:

b) opening calcium pores in the membrane

Explanation:

The opening of calcium  ions channels facilitates the migration of vesicles containing neurotransmitters in the pre-synaptic neurons  to the tip of the post-synaptic membrane. at the <u>neuromuscular  junction </u>These neurotransmitters can either be <u>cholinergic or non-chorlinergic.</u>   <u>At the tip  of the pre-synaptic membranes the vesicles empty their neurotransmitter contents into the synapse.</u>

The neurotransmitters,  diffuse through the neuromuscular junction to bind  with the receptors on the <u>post-synaptic membrane on the post-synaptic neuron.</u> This  stimulates opening of<u> ligand gated sodium ions,</u> and sodium ions  diffuse into the post-synaptic neuronal membrane, to cause <u>depolarization</u>. if the stimulus is  up to the threshold levels   it  generate action potential.

Therefore , more calcium ions channels opening produces; more diffusion of neurotransmitters;leading to opening of more sodium channels for depolarization; and IPSP or EPSP  generation.

What is an amino group made out of? What specific parts of cells can they be found in?
EastWind [94]

Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components. Both types of membranes have a specialized structure that facilitates their gatekeeping function.
