How do you get rid of homologous chromosomes? PLEASE ANSWER

Answers

Answer 1

Answer:

In metaphase I, the tetrads line themselves up at the metaphase plate and homologous pairs orient themselves randomly. In anaphase I, centromeres break down and homologous chromosomes separate. In telophase I, chromosomes move to opposite poles; during cytokinesis the cell separates into two haploid cells.

Answers

Answer:

A) Tapeworm

Explanation:

got it right on edge nuity

Peter is complaining of stomach pain and constant hunger as he was diagnosed with a worm infection.

Peter feels hungry because the tapeworm is absorbing food from his intestine as tapeworm begins to feed off your body's nutrients to grow once it invades the body.

How tapeworm infection occurs?Tapeworm infection is caused by ingesting food or water contaminated with tapeworm eggs or larvae.

When tapeworm hatches and attaches itself to your intestine, it starts feeding off body's nutrients causing increase in apatite (hunger increases).

It grows by reproducing proglottids ( chain looking body part) and the cycle continues.

Planaria upon causing infection feeds on blood cells hence can not cause apatite.

Leech and marine worm can not invade the body like tapeworm and planaria.

explain how pH and temperature can affect enzyme activity
Please help has to be due in 20 mins. Thank you for helping me.

Answers

Answer:

Enzyme activity depends on many factors such as Substrate concentration, enzyme cofactor, enzyme inhibitors, pH, and temperature. pH and temperature are two important factors that directly affect the activity of an enzyme as follows:

1. pH

Each enzyme has the specific optimal pH that allows it to perform its function to its fullest. The enzymes are the protein made up of the interaction of the hydrogen bond in the side chain of the protein. if there is any change from optimum pH, the enzyme activity decreases until it stops working.

2. Temperature:

Each enzyme has its own optimal temperature. Any modification or change in temperature results in the activity of an enzyme, and it also leads to the denaturation of an enzyme as it is made up of protein.

Two species benefit from interaction with each other

Example: A hummingbird gets food from the nectar of a flower and then spreads the nectar’s pollen, helping the flower reproduce.


: One species benefits from the interaction, and the other species is harmed but not necessarily killed

Example: Ticks feed on other animals’ blood, which can hurt the other animals.


: One species benefits from the interaction, and the other species is neither helped nor harmed

Example: Egrets rely on cows to stir up dirt and bring food to the surface, but cows do not benefit.

Answers

Answer:

D. rocks on land

Explanation:

Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks. This releases ions that are carried away to streams and rivers that eventually feed into the ocean.

Explain the unique information trace fossils and coprolites can help scientists infer about an organism

Answers

Fossils form on the under ground......

They're trace fossils, not animal bodies. This coprolite can reveal an animal's diet. Scientists can determine what animal dropped coprolites based on its shape, size, and location.

What are coprolites?

Fossilized feces are known as coprolites. Because coprolites provide information for the animal's behavior rather than its shape, rather than being considered body fossils, they are instead categorized as trace fossils.

 A coprolite  can provide researchers with information about an animal's nutrition. Scientists are able to determine the species of animal that may have been responsible for the droppings by analyzing the shape and size of the coprolites as well as the location where they were discovered.

Because coprolites have a propensity to deteriorate so quickly, we only find them very infrequently. They are the marine species that are found the most frequently. The presence of coprolites in fish and reptiles is very common.

What is needed for a fossil to form? Select all that apply.

1. The organism must first get stuck in rock.

2. The soft tissue of the dead organism must be eaten by scavengers before the bones can be preserved.

3. The tracks or burrows of an organism must be filled with sediments before they are disturbed.

4. The organism's body must be covered by sediment or another substance before its body decays.

Answers

I like 4 the best. If an organism is covered by sediment before the body decays the sediment can harden around the decaying body and the imprint will be preserved in the hardened sediment.

The correct answer is:The organism's body must be covered by sediment or another substance before its body decays.

What is the explaining statement for the same ?

Explanation: For a fossil to form, the organism's body must be rapidly buried in sediment, ash, or another substance before it can decay or be eaten by scavengers.

Over time, the minerals in the surrounding sediment or substance can replace the organic material in the bones, forming a fossil. Tracks, burrows, and other trace fossils can also form when sediment or another substance fills in the impressions left by an organism before they are disturbed.

Getting stuck in rock is not necessarily a requirement for fossilization, as fossils can also form in sedimentary rock or other types of rock.

Lack of oxygen: Decay requires oxygen, so organisms are more likely to fossilize in environments where oxygen is limited or absent, such as in deep water, bogs, or quicksand.

Low acidity: Acidic environments can dissolve bones and other hard parts, so fossils are more likely to form in environments with neutral or basic pH levels.

Lack of disturbance: Fossils are more likely to be preserved if they are not disturbed after burial. For example, if an organism's body is exposed to air or water before it can be buried, the bones may be scattered or destroyed.

Overall, fossilization is a rare and complex process that requires a combination of specific conditions to occur. As a result, the fossil record provides only a partial and biased glimpse into the history of life on Earth.
