Answer:
B. move by osmosis from solution B to solution A
Explanation:
Remember that osmosis as a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.
Answer:The image to this question is attached.
Answer is the ovary
Explanation: the process by which egg is produced is called oogenesis. It involves the mitotic division of the primodial germ cells to from a oogonia. The oogonia becomes enveloped by follicle cells . Oogonia grows to become the primary oocyte. Each primary oocyte is diploid. It then undergoes the first meiotic division to form the secondary oogonia and a smaller polar nody. all this process of development occurs in the ovary.
After it is released from the ovary, fertilization occurs and it undergoes the second meiotic division to from a polar body and an ovum.
The primary oocyte however remains in prophase of meiosis l throughout childhood.
Answer:
Option (A), (C) and (D).
Explanation:
Introns are the non coding nucleotide sequence of the gene. They may present within the gene or may lie outside the exons. Introns are responsible for the gene evolution.
Introns can also responsible for encoding the proteins subunit. Introns needs to be removed from the exons by the process known as splicing. Different splicing are alternate splice, group I and II intron. Different multiple introns can be present in the gene.
Thus, the correct option is (A), (C) and (D).
1. Two daughter cells will be produced. The cell division process known as mitosis (single cell cycle) always produces two identical daughter cells, irrespective of the number of chromosomes.
2. 72 chromosomes. As stated above, the daughter cells are identical to the parent cells and have the same amount of chromosomes.
<span>The three types of muscular tissue are skeletal, smooth and cardiac. Skeletal muscles are muscles which are attached to the bone. Their main function is to help with skeletal movements. The smooth muscles are also known as involuntary muscles. We are unable to control their movements. It is found in the walls of organs such as the stomach and the bronchi. Lastly, the cardiac muscle is the heart muscle. It is only found in the walls of the heart. Structurally, it is a combination of the skeletal muscle type as well as the smooth muscle type</span>
