Explain how a single fertilised egg cell can devolop into billions of different cells in a human adult

Biology

Alex2 years ago

Answer:

A fertilized egg cell is a single cell that can develop into one or more specific types of cells in the body. These cells include neurons, blood cells, skin cells, muscle cells, and many others. This process involves two major steps: differentiation and specialization.

During differentiation, each of the many types of cells in the body has to be developed separately. For example, skin cells have to differentiate into hair follicles, sweat glands, sebaceous glands, and so on. The developing brain cells must differentiate into a specific set of brain cells (neurons) that make up the cerebral cortex. During specialization, each of these specialized cells becomes specialized for its specific function. For example, skin cells specialize to form keratinocytes, which form the outer layer of our skin. Neurons specialize to make connections with other neurons in the brain. Blood cells specialize to carry oxygen throughout the body.

The process of differentiation and specialization is continuous, as new cells are constantly being created and old ones are constantly dying off. This continuous process of change is what allows the body to grow and develop throughout life.

The conditions on early Earth, some three to four billion years ago, are thought to be much different from what they are today. To begin with, the astronomical phenomenon called “the big bang” is defined by a theory proposing that the earth was one of the larger particles that coalesced after the initial universe explosion, or big bang, that spewed all the particles in the universe away from a central point and destined them to slowly revolve around that point. <span>

According to learning theorists:a. Behavior arises from moral beliefs.b. Moral behavior arises through reason.c. Moral beliefs a
fiasKO [112]

Answer: c. Moral beliefs arise from a habit of moral behavior that is the product of reinforcement.

Explanation:

Morality is the collection of beliefs which helps in distinguishing between the right and wrong actions. Moral beliefs are not identical to the moral behavior but are related to the moral behavior.

The theory of learning suggests that moral behavior is the outcome of the learning process that can be achieved by the reinforcement of award or punishment and also the exposure of the subject to the high order reasoning that can enhance the learning process.

Assume a population is in Hardy-Weinberg equilibrium for the B gene, which has two alleles, B and b. In this population of 100,0
MArishka [77]

Answer:

160

Explanation:

If p = frequency of dominant allele and q = frequency of recessive allele according to Hardy-Weinberg equilibrium,

p + q = 1

p² + 2pq + q² = 1

where p² = frequency of dominant homozygous genotype

q² = frequency of recessive homozygous genotype

2pq = frequency of heterozygous genotype

Here,

b = 4% = 0.04

bb = 0.04 * 0.04 = 0.0016

Number of individuals in population = 100000

Number of homozygous bb individuals = 0.0016 * 100000 = 160
