Define the components of blood and briefly describe their role.
Grace [21]
Tha main components in blood are the plasma, red blood cells, white blood cells, and blood platelets.

Plasma is like the main component that makes up most of the blood. It has a light yellow color and it carries many substances including nutrients, waste, hormones and more.

Red blood cells are the reason why blood is red in color. They have a hemoglobin inside them which can help carry oxygen for the tissues and organs. In order to maximize the oxygen carrying capacity, they don't have a nucleus.

White blood cells can be divided into phagocytes and lymphocytes. Their main function is to protect us from diseases. Phahocytes and engulf and digest bacteria, while lymphocytes can produce antibodies.

Blood platelets can cause blood clotting which can stop us from bleeding forever. They're not cells, but just fragments of cells. They also don't have nucleus since they're not complete cells.

Exposure of zebrafish nuclei to meiotic cytosol resulted in phosphorylation of NEP55 and L68 proteins by cyclin-dependent kinase
Tpy6a [65]

Answer: THEY ARE INVOLVED IN THE DISASSEMBLY OF THE NUCLEAR ENVELOPE

Explanation: The disassembly of the nuclear envelope is triggered by the cyclin‐dependent kinase at the onset of mitosis. At this point, Integral nuclear membrane proteins diffuse/move into the endoplasmic reticulum (ER) after nuclear envelope breakdown. The nuclear envelope reassembles around compact chromosome mass at late anaphase/telophase and the chromosomes condenses and become visible.

Which of the following statements is true?
Lelu [443]

Answer:

The true statement is: "Spring tides are the highest, while neap tides are the lowest."

Explanation:

  • The range of difference in the level of water between high and low tide is always larger in spring tide.
  • Neap tides are the moderate tides. It does not have huge difference in higher and low tides because the bulging of the ocean ( by the sun)  balances the bulge of the ocean caused by the moon.
  • This balance is not found in spring tides that is the main reason for spring tides to have the highest level for both higher and lower tides.

A substance with a ph of 5 is called
ddd [48]

Answer:

A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6.

Please said thanks
