3. Under which type of change would more organisms be able to survive? Why?

Answers

Most animals are well adapted to their biotic and abiotic conditions due to behavioural, physiological or structural adaptations that increase their chances of survival and reproduction. I looked it up for you

A few bacteria are placed in a nutrient solution. after several hours thousands of bacteria are present. which life activities are primarily responsible for this?

Answers

The answer is "Digestion and Reproduction"

When placing few bacteria on a nutrient solution, and for several hours it multiplies. The activities which take place in the scenario is the digestion and reproduction. Digestion occurs when the bacteria fed on the nutrient solution and Reproduction occurs when the bacteria gives birth to new bacteria.

Which of these gametes contains one or more recombinant chromosomes?

Answers

The male human has a sperm cell and the female has an egg cell. The cells from the male and female that combine to form a zygote are called gametes. The human sperm and egg cells each contain 23 chromosomes. . A combination of gametes forms a zygote with 46 chromosomes. The type of cell division that produces gametes with half the normal chromosome number is the meiosis. Meiosis is the type of cell division used in sexual reproduction. It will occur in the testes and ovaries.

The gametes B and C are the ones that contain one or more recombinant chromosomes, option 4 is correct.

Recombinant chromosomes are formed through the process of genetic recombination, where genetic material is exchanged between homologous chromosomes during meiosis. The exchange of genetic material results in new combinations of alleles on the chromosomes.

The B and C gametes are likely to contain recombinant chromosomes because they are a result of the crossing over and recombination that occurs during meiosis. Gamete B is likely to have undergone genetic recombination, as it carries a combination of alleles from both homologous chromosomes. Similarly, gamete C is also likely to contain recombinant chromosomes due to the recombination process.

The other options may not necessarily contain recombinant chromosomes, as they may have inherited intact, non-recombined chromosomes from the parent cells during meiosis, option A is correct.

Cells such as nerve and muscle cells contain more mitochondria than other cells. why? A) Nerve and muscle cells use more energy. B) Nerve and muscle cells store more nutrients C) Nerve and muscle cells degrade more proteins. D) nerve and muscle cells divide more frequently

Answers

Answer:

A) Nerve and muscle cells use more energy

Explanation:

Mitochondria are located near sites of high ATP utilization such as in muscle cells and neurons.

In the cells of the heart muscle these mitochondria are located near the contractile apparatus, which is where the hydrolysis of the ATP is carried out to generate the necessary energy in the contraction. In musculoskeletal cells the number of mitochondria is increased between 5 and 10 times when the muscle is exposed to continuous contraction.

In the neuronal cells there is a high workload suffered by the cell and a high energy expenditure
A) Nerve and muscle cells use more energy is the correct answer because the function of mitochondria is to produce energy for the cell.
