Answer:
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). Cytokinesis typically overlaps with anaphase and/or telophase. ...

Answer:
a. Genotype of the parents are; Rr and rr
b. Please find the explanation to A below
Explanation:
This question involves a single gene that codes for flower color in a plant. The allele for red flower (R) is dominant over the allele for white flower (r). This means that a plant that is heterozygous for flower color (Rr) will be red.
In a cross between a plant with red flowers and white flowers, the phenotype of the offsprings is represented as: 37 plants with red flowers and 41 plants with white flowers. Observing from this number, one would realize that the phenotype ratio is equivalent to 1:1. This phenotypic ratio is only possible when the parent with red flower is heterozygous for the gene i.e. Rr. Hence, the genotype of the parents are: Rr and rr.
b) If one were to cross Rr (red flower) × rr (white flower), the phenotypic ratio of red to white offsprings will be 1:1. Hence, judging from the ratio got from the cross of the two parents above (1:1), the parental genotypes are Rr and rr.
<h2>HER2 is Cancer cells of breast caner</h2>
Explanation:
- HER2 is a development advancing protein outwardly of all bosom cells.These malignancies will in general develop and spread quicker than other bosom diseases, yet are significantly more liable to react to treatment with drugs that focus on the HER2 protein.
- It isn't clear in the event that one test is more precise than the other, however, FISH is increasingly costly and takes more time to get the outcomes.
- In the event that the IHC result is 3+, the malignant growth is HER2-positive. This implies the HER2 status should be tried with FISH to explain the outcome.
- Triple-negative bosom tumors have relatively little HER2 and furthermore don't have estrogen or progesterone receptors. Hormone treatment and medications that target HER2 are not useful in treating these malignant growths.
- Hence, the answer of information of cancer treatment is "true"
Answer:
In vitro fertilization (IVF)
Explanation:
In vitro fertilization is conducted when infertility is perceived in sexual partners trying to have a baby. It is the process whereby matured ova/eggs are removed from the female's reproductive system and is fertilized externally in a laboratory (usually in a glassware) using a male's sperm cell. It can be thought of as a procedure where the normal fertilization process that occurs in a female's reproductive tract (fallopian tube) is carried out outside the body, specifically in a laboratory.
In order for this procedure to be employed, the male and female must be able to produce their respective gametes. The female's ovary is usually stimulated by fertility drugs in order to yield numerous eggs, which are then extracted from her ovary and fertilized by a sperm externally (in a laboratory). The resulting fertilized egg called embryo is placed back into the female's womb to carry it as a normal pregnancy.
Answer: Carbonic acid
Explanation:
The process of respiration of the terrestrial organism and marine organism leads to the exchange of gases. Due to exchange of gases, there is an entrance of carbon dioxide into the ocean and oxygen out of the ocean.
The addition of carbon dioxide into the water causes acidification of water and oxygen is diffused out of the water.
Hence, the product formed at Point A is carbonic acid.
