The gametophyte of a liverwort produces sperm in a structure called <span>antheridium.

An antheridium<span> or antherida (plural: </span>antheridia<span>) is a </span>haploid<span> structure or organ producing and containing male </span>gametes<span> which is called </span>antherozoids<span> or </span>sperm<span>.</span>
Option (A) identifies them correctly.
During Meosis 2 daughter cells are formed from a single cell and the chromosomes are equally divided in both the cells.
So, Cell P had 60 chromosome, after miosis 2 daughter cells of each having 30 chromosomes formed, and again after Miosis of from each of those 2 those daughter cells, 2 more daughter cells are formed with equal naumber of chtomosome which equals 15.
Answer:
According to the diagram shown, the section of DNA used to make the mRNA strand is known as a gene (option 2).
Explanation:
Gene consists of a DNA fragment that codes for the synthesis of a specific protein that defines the structural or functional trait of a living being.
When DNA is transcribed into mRNA, each section of transcribed DNA is part of a gene. The information travels to ribosomes in the cytoplasm where protein synthesis occurs.
A complete DNA molecule forms a chromosome, which contains the genes with information to define specific traits of a species.
The other options are not correct because:
<em> 1.Carbohydrate is a biomolecule that is not involved in the genetic process.
</em>
<em> 3. Ribosome is where protein synthesis occurs.
</em>
<em> 4. Chromosome is the complete DNA molecule.</em>
The human digestion starts in the small intestine gets the
most of the nutrients in your food, and your circulatory system passes them on
to other parts of your body to store or use.
When food enters the small intestine, villi along the intestine wall
along with enzymes help break down the food, and takes a long journey. The
stomach is right above the small intestine, and the small intestine is all
wrapped around, and isn't that thick. Nutrients from the food are released to
the whole body as energy. The small intestine brings the food to the large
intestine, which is five feet long and is near your pelvis, or hips. The large
intestine connects to the rectum, and then to the anus. In the large intestine,
all the water is absorbed as well as salt.
