Answer:
B) 2pq
Explanation:
Hardy-Weinberg equilibrium refers to a model which explains the effect of evolution on the gene pool.
The model is based on the assumptions that if no evolutionary force like genetic drift, natural selection and many other will act on the population and therefore the gene pool (gene frequency and the genotypic frequency) of a populations remains in equilibrium or constant throughout the generations.
The genotypic frequency in the model is calculated by
P² = genotype of a homozygous dominant trait
q² = genotype of a homozygous recessive trait
2pq = genotype of heterozygous trait.
Thus, P²+2pq+q²=1
In the given question, since the population is in equilibrium that is no evolutionary force is acting, therefore, the genotype frequency remains the same that is the frequency of Aa will remain same that is 2pq even after 100 generations.
Thus, Option-B is the correct answer.

Explanation:
What a Stem Cells?
Stem cells are the body's raw materials- cells from which all other cells with specialized functions are generated.
What are specialized cells?
Specialized cells perform specialized functions in multicellular organisms. Groups of specialized cells cooperate to form a tissue, such as a muscle.
What are unspecialized cells?
An unspecialized cell that can give rise to one or more different types of specialized cells, such as blood cells and nerve cells.
Do you think stem cell research should be allowed?
By watching stem cells mature into cells in bones, heart muscle, nerves, and other organs and tissue, researchers and doctors may better understand how diseases and conditions develop.
Answer:
Brain is the main coordination center of the body and regulates the proper functioning of the body. Brain is divided into three parts- forebrain, midbrain and hindbrain.
Cerebrum: Crerebrum is the largest part of brain and controls the language, communication ability, and the process of learning and memory of an organism.
Hypothalamus: Hypothalamus is located at the base of a brain. Hypothalamus releases various hormones, regulates the body temperature and manages the sexual behavior of an organism.
Thalamus: Thalamus is located above the brain stem and relay the neurons into the cerebral cortex. Thalamus regulates alertness, wakefulness and sleep of an organism.
