g It has been proposed that integrin proteins undergo conformational changes when they bind to small molecules diffusing into the extracellular matrix. Because integrins are transmembrane proteins, a change in their conformation can be transmitted across the membrane to the portion of the protein that interacts with intracellular structures. What biological role does this allow integrins to play in a cell's function within a multicellular organism

Answer:

Cell-cell communication

Explanation:

Integrins are heterodimeric transmembrane receptors that facilitate the adhesion to the cell-extracellular matrix by attaching the cytoskeleton to this matrix. Moreover, integrins also help the cells bind with other cells. Integrins are responsible for the communication between cells and thus control tissue structure. These receptors are responsible for the attachment of fibroblasts to collagen, as well as the attachment of fibroblasts to fibronectin. It is also important to highlight that the binding of integrins with their corresponding ligands activates signaling pathways that control diverse cellular processes including, among others, cell growth, cell development, cell migration, phagocytosis, etc.

A medical student is studying how the volume of blood in the circulatory system affects blood pressure. He measures the blood volume and pressure of two classmates, a man and a woman. He finds that the man has a higher blood volume but a lower blood pressure than the woman. He concludes that a person with low blood volume would tend to have high blood pressure. What additional factors should the student consider that would most likely affect blood pressure? (1 point)

On average, an adult male sea otter weighs 36 kg (79 pounds), with some individuals weighing as much as 45 kg (99 pounds). A female weighs an average of 23 kg (50 pounds). To maintain their weight, otters must consume 250 kilocalories/kg of body weight each day to survive. Otters eat almost entirely small invertebrates for which they must dive to catch.

You have been tracking an adult female otter who weighs 25 kg. Answer the following questions based on the data provided.

How many kilocalories must she consume each day to maintain her body weight?



Question options:

6,250 Kcals


275 Kcals


1,620 Kcals


9,000 Kcals

6. An adult male red fox weighs 8 kg (kilograms). In order to maintain his
weight and survive, he needs to intake 59 Kcal/kg of body weight per day.
This means he needs to consume 59 Kcal for every one kg of his body
weight.
How do we determine the number of Kcal per day for the fox?

39. Europa is one of Jupiter's moons. Its surface is covered with frozen water. It is far from the sun and has only a very thin atmosphere, so its surface is considered to be too cold to support life. Beneath the ice, however, there are probably liquid oceans rich in oxygen, kept warm by heat that escapes from Europa's core.​
