1.The illustration below shows that sexual reproduction involving two parent pea plants resulted in the production of four offspring.

A. All four offspring received all of their genetic information only from Parent 1 and are therefore identical to that parent

B. All four offspring received all of their genetic information only from Parent 2 and are therefore identical to that parent.

C. All four offspring are genetically unique and did not receive any of their genetic information from either parent.

D. Each of the offspring is genetically unique and received some of its genetic information from each parent, so each has some traits in common with each parent.

Answers

Answer:

C

Explanation:

Because of the x and y chromosomes and they split apart and that's how you get 4 offspring.

The fusion of two different gametes leads to the formation of new offspring is called reproduction. There are two types of reproduction that is sexual and sexual.

The correct option is A

The branch of biology which deals with the study of genes is called genetics. there are two types of alleles that give all the character to the phenotypes. The dominant allele is the allele that suppresses the recessive allele and shows its effect.

In question, the F1 generation shows only one type of character which belongs to parent 1 because that is the dominant allele.

Hence, the correct option is A that is all four offspring received all of their genetic information only from Parent 1 and are therefore identical to that parent

The mitochondrion creates energy for the cell (powerhouse).

Ribosomes create proteins (protein synthesis).

The cell membrane is a barrier that lets certain molecules in and out of the cell.

The smooth endoplasmic reticulum is involved in metabolic processes such as synthesizing lipids.

The rough endoplasmic reticulum contains ribosomes that make proteins.

There are fewer organisms at the top of the food chain because there is

less energy available for life processes is the best statement that supports

it.

What is Trophic level?

This is the position an organism occupies in a food chain. The organisms

are usually fewer while those at the bottom have more organisms present

in the chain.

As food chain moves from bottom to the top, the energy level decreases

Explain why methicillin resistant Staphlococcus aureus (MRSA) is more prevalent now than it was only 30 years ago. See Section 1.7 (Page) . Explain why methicillin resistant Staphlococcus aureus (MRSA) is more prevalent now than it was only 30 years ago. See Section 1.7 (Page) . Methicillin resistance causes an infection to spread more rapidly. Antibiotics cause mutations in Staphlococcus aureus that lead to an increase in the number of methicillin-resistant strains. Frequent and inappropriate use of methicillin-type antibiotics has provided selective pressure that has resulted in an increase in the proportion of methicillin-resistant strains of Staphlococcus aureus. Diseases like AIDS have made people more vulnerable to infections from Staphlococcus aureus.

Answers

Answer: Frequent and inappropriate use of methicillin-type antibiotics has provided selective pressure that has resulted in an increase in the proportion of methicillin-resistant strains of Staphlococcus aureus.

Explanation: The methicillin resistant Staphlococcus aureus is an example of the Theory of Evolution explained by Darwin. He stated that evolution is brought by 3 principles: Variation - the variety of species allows them to adapt better in the environment; Heridity - when those characterists necessary for survival passes on to the next generation; Natural Selection - the organism which is the most adapted to the environment survives to passes on their characteristics;

In a strain of Staphlococcus aureus, there are strains which are resistant to the antibiotics. The constant use of the medicament, and sometimes, the misuse of it, can select those strains which are resistant. As these characteristics are crucial for their survival, they are passed on to the next generation.

This is why the rate of methicillin-resistant Staphlococcus aureus has increased along the years.

the process of taking gaseous carbon dioxide or oxygen by leaves is termed​

Answers

Answer:

photosynthesis

as in the process of photosynthesis plants take in carbon dioxide and give out oxygen.

hope it helps you

please mark me as brainlist

The process of taking gaseous carbon dioxide or oxygen by leaves is termed​ peristomal diffusion or diffusion through stomata present on leaves.

Plants take up carbon dioxide or oxygen from the air through their leaves as they have several stomata on their surface. The small holes or openings in the underside of the leaf are called stomata.

Diffusion through stomata also helps oxygen, produced in photosynthesis, to leave the leaf.The diffusion of gaseous carbon dioxide or oxygen is proportional to the concentration difference between the atmosphere and leaves.The loss of water vapor in transpiration also occurs through stomata.peristomal diffusion or diffusion through the leaves allows the gaseous exchange.

Thus, the correct answer is - peristomal diffusion or diffusion through stomata present on leaves.
