Scientists have found that extracellular matrix components may induce specific gene expression in embryonic tissues such as the

liver and testes. For this to happen, there must be direct communication between the extracellular matrix and the developing cells. Which kind of transmembrane protein would most likely be involved in this kind of induction? (A) integrins (B) fibronectins (C) actin microfilaments (D) receptor tyrosine kinases

Scientists have found that extracellular matrix component may induce specific gene expression in the embryonic tissues such as the liver and testes. For this to happen, there must be a direct communication between the extracellular matrix and the developing cells. The Integrins of transmembrane protein would most likely be involved in this kind of induction.

Integrins are the main principal receptors used by the cells of  animal to bind to the matrix of extracellular. They are heterodimers and they function as transmembrane linkers between the actin cytoskeleton and the extracellular matrix. A cell can regulate the sticky activity of its integrins from within.

4. Did the complete process of photosynthesis take place in the way you modeled it in this activity? Explain your answer.
Dafna1 [17]
Well I dont know exactly how you modeled your model in this activity (also, I notice this is a question from 2016), but I do know the two processes.

This is the process of making glucose in plants. Photosynthesis goes through two individual stages:  
Stage 1: L<span>ight dependent reaction</span> (depends on the presence of light; it can’t happen in the dark) 
Stage 2: Light independent (dark reaction) (works in the absence of light, but calling it a dark reaction might be misleading; It can just as well happen in the presence of light).

Otrada [13]
So base on the question that states and ask to give the name of one cell type that continues to divide throughout a person's lifetime and also on who does not, with that question, the cell that divide through persons lifetime is a Mitosis or skin cells, an example to this is the skin, and the who doesn't divide is i think the brain cells, it doesn't regenerate

There are no known motor proteins that move on intermediate filaments (IFs).
Harlamova29_29 [7]

Answer: The correct option is E ( Intermediate filaments are unpolarized).

Explanation:

Intermediate Filaments are usually associated with cells that can withstand mechanical stress which includes claws of animals, hair and makes up the dead remnants of the epidermal cell of the skin. Therefore without the supporting network of intermediate filaments, an epithelium remains intact but the cells are prone to damage by abrasive forces.

Intermediate filaments are so named because they are thicker than actin filaments and thinner than microtubules or muscle myosin filaments

The properties or characteristics of an intermediate filaments that explains the lack of motor proteins is as a result of its subunits which are elongated, not globular and are associated in an anti-polar manner. Therefore, the overall filament has no polarity, and therefore no motor proteins move along intermediate filaments

A 60 year-old man has long managed his type 1 diabetes effectively with a combination of vigilant blood sugar monitoring, subcut
ivanzaharov [21]

The question is incomplete as it lacks the multiple options. The multiple option are as follows;

Careful monitoring for level of consciousness and resolution of hypoglycemia .

IV infusion of 50% dextrose and water solution .

Administration of subcutaneous glucagon

Administration of 15 to 20 g of glucose in a concentrated carbohydrate source

Answer:

Administration of 15 to 20 g of glucose in a concentrated carbohydrate source.

Explanation:

The insulin and glucagon hormone maintains the blood glucose level in the humans. In case of Type I diabetes a little amount or no amount of insulin is made by the pancreas.

The wife of a man has caused insulin error that creates hypoglycemic condition means the individual has low blood glucose level. The intake of carbohydrates can increase his blood glucose level. The wife should give 15 to 20 g of glucose to make the conditions normal.

Thus, the answer is option (4).
