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.
In mitosis, the first stage is prophase. The
nucleolus disappears and the two centrosomes begin to form the mitotic spindle.
The spindle xtends between two opposite poles f the cell. Next is the
metaphase. The centromeres of the chromatid pairs align at the center of the
miotic spindle. Then anaphase, the centromeres will split that separates the
chromatid pair. They are now called chromosomes. The last phase is the
telophase. The chromosomes will then form a thread-like chromatin and for ache
envelope, a nucleoli appears. <span>The type of
cell division that produces gametes with half the normal chromosome number is
the meiosis. Meiosis is the type of cell division used in sexual reproduction.
It will occur in the testes and ovaries.</span>
Answer:
Below:
Explanation:
Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
Explanation:
<h2>They are aquatic — found in moist or wet places.</h2>
<h2>They are autotrophic, and the reserve food is generally Starch.</h2>
<h2>They consist of a cellulose cellwall around their cells.</h2>
<h2>Mechanical and conducting elements are absent in thallophyta.</h2>
<h2>Plant body is thallus, not differentiated into root, stem and leaves</h2>
