contain?
a
28
b

с
56
d
14

Answers

Answer:

D

Explanation:

after mitosis II the daughter cell will have half of the chromosomes the father cell has.

A cell containing 28 chromosomes undergoes mitosis and cell division, and then each daughter cell will contain 28 chromosomes too, as the mitosis is the equational division that is in option a.

What is the significance of mitosis?

Mitosis is an essential process that plays a crucial role in the growth, repair, and other essential processes that occur in all living organisms, such as growth and repair by producing new cells to replace old or damaged ones, mitosis helps in development as it creates the vast number of cells needed to form the complex structures of the body and takes part in asexual reproduction.

Hence, a cell containing 28 chromosomes undergoes mitosis and cell division, and then each daughter cell will contain 28 chromosomes too, as the mitosis is the equational division that is in option a.

If these organisms were arranged in energy pyramid, which organism would have the least amount of total available energy in relation Insect, coyote, lizard or shrub

Answers

Answer:

The correct answer is - coyote

Explanation:

In this food chain like other food web or chain, the producer makes their food and are photosynthetic plants which are fed by primary consumers or herbivores. Secondary consumers prey on these primary consumers and top predators eat these secondary consumers. In energy pyramid, the producer has the highest amount of energy and its decreases with the tropic level as only 10 percent of total energy move to next trophic level.

In these organisms, shrubs are a producer with the highest amount of energy, and it decreases with insects (primary consumer), then lizards secondary consumer and least amount of energy in coyote.

Answers

Answer:

The correct answer is - per gram, the marathon runner's muscles would contain more myoglobin than the sprinter's muscles.

Explanation:

Marathon runners have smaller leg muscles and thinner quads and calves as marathon runners require slow-twitch muscles while in sprinters the fast-twitch muscle requires. Slow-twitch muscles of marathon runners have more amount of myoglobin, per gram than fast-twitch muscles.

Myoglobin acts as local oxygen storage that provides oxygen to the muscles in case of less oxygen supply than required temporarily and a marathon race is an intense exercise or activity that requires more oxygen.

1-What are some ways in which metamorphosis helps the animals that undergo it?​

Answers

Answer:

During metamorphosis, they undergo a change in body chemistry that enables them to live in salt water. In biology, metamorphosis is the process by which an animal develops continually, after birth or hatching. This involves the change in body structure; both internal and external features, regulated by hormones. Metamorphosis is occasionally accompanied by changes in the animal’s behaviour, physiology and biochemistry.

Explanation:

During metamorphosis, they undergo a change in body chemistry that enables them to live in salt water. They change color during metamorphosis as well. The salmon must return to fresh water in order to spawn (breed). Fish that live in the ocean as adults but spawn in fresh water are anadromous. Lampreys go through a period of metamorphosis

Answer:

feeding

Explanation:

when an organism eats another, it gets energy from it. That energy is passed along the food chain

The process by which energy is transferred from organisms at one stage in a food chain to organisms at the next is by feeding, which is present in the second option, as through the eating process and the predator-prey relationship, energies pass.

What is the significance of the food chain and the energy transfer?

The food chain in nature is made up of many trophic levels, where one trophic level animal preys on other animals or plants and obtains food from them, so when the animal is eaten by other animals, the energy content passes from one to another, and the energy content from plants continues to decrease to the topmost trophic levels.

Hence, the process by which energy is transferred from organisms at one stage in a food chain to organisms at the next is by feeding, which is present in the second option, as through the eating process and the predator-prey relationship, energies pass.

Which of the following is the best representation of the limiting factors affecting the elk population in this ecosystem?
O Number of scavengers, number of wolves, number of scientists studying Yellowstone.
Number of scavengers, and harshness of winter
Number of wolves, and harshness of winter.
The elk have no limiting factors

Answers

Answer:

Number of wolves, and harshness of winter.

Explanation: I took the test

The combination of factors that is capable of limiting the population of elk in an ecosystem would be the number of wolves and the harshness of winter.

The limiting factors of a population are those factors that hinder the population of an organism from increasing unlimitedly. In other words, limiting factors hinder populations from reaching their biotic potentials.

Limiting factors can be density-dependent if they have correlations with the density of species or density-independent if they have no correlation with an organism's density.

Wolves generally prey on elks, so they limit the growth of elk's population in an ecosystem. A harsh winter will also limit the overall growth of the population of elk in an ecosystem.

Scavengers cannot be a limiting factor to elk's population because they only feed on carcasses.
