Answer;
Follicle- stimulating hormone (FSH)
Explanation;
-Follicle stimulating hormone is produced by the pituitary gland. It regulates the functions of both the ovaries and testes. Lack or insufficiency of it can cause infertility or sub-fertility both in men and women.
-Follicle stimulating hormone is one of the hormones essential to pubertal development and the function of women’s ovaries and men’s testes.
-In women, this hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation. It also increases oestradiol production. In men, follicle stimulating hormone acts on the Sertoli cells of the testes to stimulate sperm production.
The chromosomal mutation is C. Nondisjunction .Therefore , C. Nondisjunction is correct .
There are a number of factors that can increase the risk of nondisjunction, including:
Age: The risk of nondisjunction increases with age, especially in women.
Genetic factors: People with certain genetic conditions are at increased risk of nondisjunction.
Environmental factors: Exposure to certain environmental toxins, such as radiation, can also increase the risk of nondisjunction.
There is no cure for nondisjunction, but there are a number of things that can be done to manage the symptoms and improve the quality of life of people with nondisjunction-related birth defects.
Here are some additional details about nondisjunction:
Nondisjunction can affect any chromosome, but it is most common on chromosomes 21, 13, and 18.
Nondisjunction is estimated to be the cause of 50-60% of all miscarriages.
Nondisjunction is also the cause of some stillbirths and birth defects.

Identification of mutation type, such as point mutation, silent mutation, insertion, deletion, transversion, or transition, depends on the specific changes in DNA or RNA sequences. For example, a change in a single base pair signifies a point mutation.
A thorough identification of the type of mutation seen on Chromosome 20 goes beyond merely looking at the question diagram. It depends on the specific alteration of the DNA or RNA sequences. Several types of mutations exist including point mutations, silent mutations, insertions, deletions, transversions and transitions, among others.
As an illustration, suppose the mutation involved a single base pair alteration, this would be a point mutation where one nucleotide is substituted with another. Transversions involve switching a purine with a pyrimidine or vice versa. If the mutation led to an addition or removal of a base pair, this would be termed an insertion or deletion respectively. Occasionally, a fraction of DNA from one chromosome may get transported to another chromosome or a different part of the same chromosome, a scenario known as translocation.

Red data book contains the list of endangered species. Asiatic lions are declared as endangered because of their small population size.
A Red Data Book is a record of all the animal, plant, and fungal species that are in risk of extinction in a certain nation or state. The Red Data Book was created by the International Union for Conservation of Nature to protect endangered rare plant and animal species.
The Red Data Book aids in providing thorough information for studies and research on the animal species and subspecies that are in risk of extinction. The Red Data Book is one of the most significant concepts in the study of animal biodiversity.
Therefore, name of Asiatic lions, being endangered is in Red Data Book.

community, ecosystem, population
The correct answer is: population, community, ecosystem.
Answer:
Option A, most closely related to mammals
Explanation:
Insects like arthropods and molluscs have an open circulatory system and thus do have a distinguishable heart. Fish has two chambered heart. Reptiles have three chambered heart. Amphibians too have a three chambered heart.
All mammals and fish have four chambered heart. The right and left sides of the chambers have restricted entry and hence remain intact from each other
Hence, option A is correct
Geothermal energy is the heat and electricity produced by using the heat from the Earth's interior. It exists because the Earth grows progressively hotter with increasing depth.
