<h2>Peristalsis </h2>

Explanation:

  • Peristalsis is simply a series of muscle contractions, these contractions occur in the digestive tract
  • Peristalsis is also observed in the tubes that connect the kidneys to the bladder
  • Peristalsis is an automatic and important process which moves: food through the digestive system, urine from the kidneys into the bladder  and bile from the gallbladder into the duodenum

Below are two graphs showing zero growth isoclines in phase space for plant species A and B, with insect herbivores present (lef
bezimeni [28]

Insect herbivory is likely to affect the competitive relationship between the species in that a plant affected by these insects will have a hard time competing with those who are unbothered by the insects.

<em>Although I could not locate the Graph or options for this question online, I can offer a general assessment to help you answer the question.</em>

<em />

<em />

Insect herbivory is when insects consume plants or parts of a plant as their main food source. Interestingly, this term also applies to those insects who do not harm the plant, but consume the pollen, etc.

However, focusing on harmful insect herbivory, we can assume that in the presence of these insects a plant will have a hard time staying alive or mating effectively due to the damage caused. Therefore, we can assume that <u>the </u><u>plant </u><u>on the </u><u>left </u><u>will not be able to stay </u><u>competitive</u>.

Fat-soluble hormones pass through the cell membrane easily. Such hormones are referred to as _________________.
anastassius [24]

Answer:

Steroid hormones

Explanation:

Steroid hormones are the second largest groups of hormones. They are made up of small cholestrol units and are fat soluble, therefore they can pass easily through cell membranes.

Function:

They have roles in many vital functions of our body such as salt and water balance, formation of sexual traits,immunity related functions,metabolism and improving health by withstanding injuries.

Mode of action:

  • Steroids being hormones can effect the processes of body in two ways: They affect the transcription of genes involved in synthesis of certain proteins- this is called genomic level action.
  • They can affect by binding with specific membrane receptors like G-proteins, Ion channels and transporters- non genomic level function. Through these ways, they can affect many mechanisms occurring inside the cell.

Hope it helps!
