1. Genomic imprinting is permanent in the somatic cells of a given individual. _____________
2. Genomic imprinting is permanent and affects future generations. ____________
3. Methylation is the chemical change underlying genomic imprinting. _____________
4. If a gene is imprinted, the offspring can express both the maternal and paternal allele. _________

Answers

Answer:

1. True.

2. False.

3. True.

4. False.

Explanation:

A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).

Genome imprinting can be defined as an epigenetic biological process in which a genomic domain or genes of a living organism is marked biochemically with information that is related to parental origin. Thus, it is a non-Mendelian inheritance i.e genome imprinting is typically independent of Mendelian inheritance.

1. True: Genomic imprinting is permanent in the somatic cells of a given individual.

2. False: Genomic imprinting is permanent and affects future generations. It does not affect future generations because generally it is expressed in a parent of origin specific form.

3. True: Methylation is the chemical change underlying genomic imprinting.

4. False: If a gene is imprinted, the offspring can express both the maternal and paternal allele. It is independent of Mendelian inheritance.

What is antagonist muscle?

muscles can only pull. They typically work a joint in pairs because of this. When a body part is moved, one of the pair's muscles contracts; when the body part is brought back to its starting position, the other muscle in the pair contracts.

Antagonizing pairs of muscles are those that function in this way. When two muscles are antagonistic, one contracts while the other relaxes or lengthens. The muscle that is lengthening or relaxing is referred to as the antagonist, while the muscle that is contracting is referred to as the agonist.

Therefore, A accomplish this task, and muscle C does the opposite of A, then muscle A is a antagonist to prime mover.

Which is the general equation for cellular respiration?
A. carbon dioxide + water + energy --> oxygen + glucose
B. glucose + energy --> carbon dioxide +oxygen + water
C. carbon dioxide + glucose --
--> water + oxygen + energy
D. glucose + oxygen --> water + energy + carbon dioxide

Answers

Answer:

D. glucose + oxygen ⇒ water + energy + carbon dioxide

Explanation:

The reactants of cellular respiration, or the substances that are used for the beginning of the chemical process, are sugar (glucose) and oxygen. The products, or the results of cellular respiration, are water, carbon dioxide, and ATP energy. Thus, D is the answer.

The general equation for cellular respiration is glucose + oxygen --> water + energy + carbon dioxide, which is in option D. So, here, the correct answer is option D.

Glucose is a sugar molecule that serves as the primary source of energy for cells. It is derived from the breakdown of carbohydrates in the diet or can be produced through other metabolic processes. Oxygen is required for cellular respiration as the final electron acceptor in the electron transport chain. It is obtained from the air through breathing or from other sources in organisms that do not respire aerobically. During cellular respiration, glucose and oxygen undergo a series of metabolic reactions in different stages, including glycolysis, the citric acid cycle, and oxidative phosphorylation. The correct option is option D.

What is Fertilization in plants?

Fertilization is defined as the process of sexual reproduction, which occurs after pollination and germination which can be defined as the fusion of male gametes called pollen with female gametes called as ovum to form diploid zygote. It is a physio-chemical process that occurs after pollination of the carpel.

Steps of Fertilization occur in Plants

1. Pollination

2. Germination

3. Fertilization

Fertilization occurs through the pollen tube opening into the ovule through the micropyle and bursting into the embryo sac where the male nucleus fuses with an egg nucleus inside the ovule to form a diploid zygote, which then swells and develops into a fruit. These plants are similar in appearance when grown from seed but with the tuber method they will appear identical but not with the mother.

Thus, they will look the same because the plants grown from seeds are genetically identical to one another but not to the mother plant. So, the correct option is (A).

Pollinization is the transference of pollen grains to the stigma. Fertilization occurs when pollen grains move to the ovary and gametes meet. Option D. 2,3,4,1

What is pollinization?

Pollinization is the pollen transference from the masculine organs to the feminine organs of the flower. It might involve the same flower or different flowers, the same plant or different plants.

What are the Feminine reproductive structures?

The central structure is known as a carpel, also recognized as the pistil.The base of the carpel forms the ovary, in which the eggs are produced and where the zygote develops.The opposite extreme of the carpel is the stigma, in the superior part. The stigma is a sticky surface where the pollen grains get attached.The style is the filament structure that connects the ovary and the stigma.

What are the Masculine reproductive structures?

The pollen grains, or male séx cells, are produced in the stamens.

The stamen has an anther where the pollen is produced, and a filament that provides support.

What is fertilization?

Fertilization is the gamete fusion, which involves the mature germinated pollen grain and the ovule.  

During fertilization

1) The mature pollen grains are driven to the stigma of the same flower or other flowers of the species, where they stick.

2) Once in the stigma, the pollen grain germinates.

3) A thin structure named pollinic tube forms. It goes from the stigma along the style and ends in the flower ovary.

4) The pollen grains move along the tube forward to the ovary, where they meet the egg and fertilize.

5) Once in the ovary, the pollen grains get in touch with the ovule. They have double fertilization.

6) The zygote develops in the ovary.

How can the type of bedrock under soil affect the characteristics of the soil? *

by absorbing water
by making the soil more fertile
by weathering and becoming new parent material
by providing surface area for nutrient accumulation

Answers

Answer:

by weathering and becoming new parent material

Explanation:

Soil formation occurs as a result of the the decay or the remains of plants and animals which are used up.

Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;

I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.

II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.

Hence, the type of bedrock under a soil affect the characteristics of the soil by weathering and becoming new parent material i.e the contribution of small rock particle to the soil.
