After the skin is cut and a capillary wall breaks, what's the first step in working to form a clot? A. A set of reactions are triggered. B. Thrombin causes sticky fibrin filaments to form the clot. C. The clot seals the area to prevent further blood loss. D. Platelets clump at the site.

Answers

Answer 1

Answer: The best answer is A.As soon as the blood vessel wall is broken or damaged, a series of reactions activate platelets so that they stick to the site of injury. The platelets are able to hold to the blood vessel wall by means of a protein substance called von Willebrand's factor.Collagen and thrombin then act at the site of injury and induce platelets to clump or stick together, forming a mesh that plugs the broken part. Special clotting protein help sequester more platelets to the plug which finally becomes a blood clot.

One advantage of having a cloned flock

Answers

Answer:

Producing transgenic animals has practical advantages, such as using less than half of experimental animals for the production of an envelope.

Explanation:

Currently it is only possible to add genes, the transgenic sheep that exist are found to produce human proteins. However, it is convenient for some proteins to remove endogenous proteins from milk. For example, for human serum albumin.

There is a high demand for some human proteins for the treatment of various diseases. Small quantities can be produced in cell cultures but the cost is very high. Higher amounts can be made by bacteria or yeasts, but proteins are difficult to purify and that is why some of the advantages of having transgenic animals is the amount of protein produced.

it eliminates certain genetic diseases or bad traits for the flock.

One of the differences between a plant and animal cell can be found surrounding the outer cell structure of the plant cell. this part of the plant cell is made of specialized sugars called cellulose. it provides structure and support to the plant cell. what is this structure?

Answers

The cell wall. It is one of the main differences of the plant and animal cells. The animal cell does not have a wall to regulate what goes in and what goes out of the cell, unlike the cell of a plant.

Hello there!

The answer to your question is: Cell wall.

The main difference (in this case) between a Animal cell and a Plant cell is that Plants cell has a "cell wall" while Animal cells do not.

3. Draw a pH scale and label water, hydrochloric acid, and sodium hydroxide in their general areas on the scale.

Answers

Answer:

The pH scale has been drawn below.

Explanation:

pH sacle may be defined as the scale that determines the pH of acids and bases. 0 represent the neutral compounds. The compounds that pH less than 7 acts as acid whereas the compounds that have pH greater than 7 acts as base.

Here, water is neutral, Hydrochloric acid (HCl) is acidic and sodium hydroxide (NaOH) acts as base.

Water, hydrochloric acid, and sodium hydroxide can be placed on the pH scale as follows:

Water: Water is considered neutral and has a pH of 7. It falls in the middle of the pH scale.

Hydrochloric acid: Hydrochloric acid is a strong acid and is highly acidic. It has a pH below 7. The exact pH value of hydrochloric acid may vary depending on its concentration, but it typically falls within the range of 0 to 2.

Sodium hydroxide: Sodium hydroxide is a strong base and is highly alkaline. It has a pH above 7. Again, the specific pH value of sodium hydroxide can vary based on its concentration, but it typically falls within the range of 12 to 14.

So, on the pH scale, water would be placed at pH 7 (neutral), hydrochloric acid would be placed below pH 7 (acidic), and sodium hydroxide would be placed above pH 7 (alkaline).
