Genomic imprinting may involve a single gene, a part of a chromosome, or a whole chromosome. Indicate if the following statements are true or false regarding this phenomenon
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

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.

Light waves are a type of electromagnetic wave.
The wavelengths of light range from 400 nm to 700 nm.
Light waves are transverse waves
• The speed of light is 3 x 108 m/s.
Which statement can be inferred from the data?
O Light waves can transport matter through mediums and empty spaces.
O Light waves transmit energy by compressing the particles in mediums.
O Light waves can travel with and without mediums.
O Light waves transfer the particles of mediums in the direction of travel.

Answers

Answer:

Light waves can travel with and without mediums.

Explanation:

Light waves are a type of electromagnetic wave. Some of the characteristics (properties) of light waves include;

I. The wavelengths of light range from 400 nm to 700 nm.

II. Light waves are transverse waves.

III. The speed of light is 3 x 10^8 m/s.

Therefore, from the aforementioned characteristics it can be inferred that light waves can travel with and without mediums.

This ultimately implies that, light wave is an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.

The purpose of "crossing over" is
A. to add genetic diversity
B to pull the chromosomes away from each other
C to make identical copies of the parent cell
D to help dissolve the nuclear membrane

Answers

Crossing over is a process that happens between homologous chromosomes in order to increase genetic diversity. During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material.

Maintaining blood glucose levels is an important homeostatic activity of the body, not specifically because every cell of the body must have glucose but primarily because the brain relies on glucose for its metabolism.

a. True
b. False

Answers

Answer:

a. True.

Explanation:

Even though the cells in our body rely on glucose as a source of energy, they can replace glucose's energy with lipids or proteins' energy. In the brain's case, this is not possible since the blood-brain barrier, which is a highly selective barrier between the blood and the extracellular fluid in the central nervous system, allows the passage of glucose as the only source of energy. This is why maintaining the correct levels of glucose is crucial for the metabolism in the brain.

o decrease erosion
o promote soil compaction
O promote fertilizer retention

Answers

Answer:

Increase erosion because the soil is being loosened

Explanation:

Tillage can release pollutants in the soil and  - option. increase erosion which is applied to conventional tillage.

The preparation of the soil by mechanical agitation such as digging, plowing, overturning, and other ways, in agriculture for the purpose of plantation and cultivation of crops.

Disadvantageous of Tillage:

causes an eventual loss of soil production.accumulating pollutants in topsoil due to the movement of the components present in the soil.Increases in erosion rates due to loose soil.The destruction of earthworm pathways and root channels leads to a decrease in the quality of the soil.

Thus, the correct answer is - option. increase erosion

Macronutrients can be stored by the body for later use when it enters into the fasted state.

a. True
b. False

Answers

Answer:

a. True

Explanation:

The statement being made is true. The Fasted State is where our bodies draw  from glycogen and fat reserves in order to create energy. This happens only when we do not eat that we enter into this state. The body first needs to draw all the energy it can from the glycogen stores and then once that is depleted it then begins to draw from fat stores for energy. Using all the stored macronutrients and turning them into energy to sustain the body.

Answers

Answer/Explanation:

Recall:

Volume of a sphere = ⁴/3πr³

Surface Area = 4πr²

✔️For radius (r) = 1 mm:

Volume = ⁴/3 × π × 1³ = 4.19 mm³

Surface Area = 4 × π × 1² = 12.57 mm²

Ratio of volume to surface area = 4.19 : 12.57 = 1:3

✔️For radius (r) = 3 mm:

Volume = ⁴/3 × π × 3³ = 113.1 mm³

Surface Area = 4 × π × 3² = 113.1 mm²

Ratio of volume to surface area = 113.1 : 113.1 = 1:1

B. Crossing 2 plants w desirable traits
C. Inserting genes from one plant into another
D. Returning bred plants to their natural habitat

Answers

Answer:

b

Explanation:

they chose the best tomatoes to make even better ones

Breeding tomatoes to increase fruit size is an example of selective breeding. Therefore option A is correct.

Selective breeding, also known as artificial selection, involves the intentional breeding of plants or animals to promote desired traits. The process typically involves selecting individuals with specific characteristics and breeding them to pass on those traits to the next generation.

In the given options, breeding tomatoes to increase fruit size is an example of selective breeding. By carefully selecting tomato plants with larger fruits and allowing them to reproduce, breeders can gradually enhance the fruit size of future generations.

This process relies on natural genetic variation within the tomato population and human intervention to guide the breeding process toward the desired outcome.
