Even though the female only produces eggs with half the number of chromosomes, during parthenogenesis. how is she able to produce an offspring (zygote) with the full number of chromosomes?

Answers

during meiosis both females and males create gametes (sperm and egg) each gamete having 23 chromosomes from mom (the egg) and 23 chromosomes from the dad (the sperm) during fertilization the egg and sperm come together creating a child with all 46 chromosomes (not sure if this was exactly what you were asking but lol)
Normally, meiosis causes each parent to give 23 chromosomes to a pregnancy. When a sperm fertilizes an egg, the union leads to a baby with 46 chromosomes.

Which is the best Prediction? (PLEASE ANSWER ASAP!! I WILL AWARD BRAINLIEST) (image below)

1. Prediction 1 is best. Two brown or gray foxes had a baby with a mutation in its genes for the white-fur trait. Because white foxes are more likely to survive, that baby survived long enough to pass on its mutation, so the white-fur trait became more common over generations.


2. Prediction 1 is best. White foxes are more likely to survive, so brown and gray foxes began to have offspring with mutations in their genes for the white-fur trait so that their offspring would have a better chance of surviving.


3. Prediction 2 is best. A fox could have been born with a mutation in its genes for the white-fur trait and lived for a little while. Because white foxes are more likely to die, it would have been more likely to die before it had offspring, so the final population will only have brown and gray foxes.


4. Prediction 2 is best. A fox could have been born with a mutation in its genes for the white-fur trait, but having a mutation in its genes would have caused it to die when it was born, so the final population will only have brown and gray foxes.

Answers

Answer:

i believe it's 1)

Explanation:

answer choice 1) makes the most sense to me because the white fox had to have had a mutation in it's genes-which all the answer choices say, but you have to remember that at one point in time they were the dominant 'race' or color because of the snowy environment so, seeing as how the lighter colored fox is more likely to survive, answer choice 1) is the correct answer

3. explain what happens to digested food in the small intestine

4. write a sentence that describes what happens to digested food in the cell.

Answers

Answer:

The stomach stores swallowed food and liquid, mixes the food and liquid with digestive juice it produces, and slowly empties its contents, called chyme, into the small intestine. The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Specialized cells help absorbed materials cross the intestinal lining into the bloodstream. Explanation: hope i wasnt to late! good luck!

D- the mountains are evidence of plate tectonics

Similar mountain ranges found on different continents supports the theory of plate tectonics. Therefore, option (D) is correct.

What is the plate tectonic theory?

Plate tectonics is a scientific theory that attempts to explain the formation of significant landforms on Earth as a result of the movement of the Earth's tectonic plates.

Where two continental plates clash, mountains are created. Due to their identical weight and thickness, neither plate will bury beneath the other. Instead, they fold and collapse, pushing the rocks upward to create a mountain range. Mountains will continue to rise in height as the plates continue to collide.

Answer:

Option A. Leaving the trees and other plant cover on the hillsides.

Mudslide: When a bulk of soil slides down a steep hill or mountain causing damage to the flora and fauna of the place.Mudslide leads to soil erosion in hilly areas.There are various causes of mudslide such as:Heavy rainfall that pushes the soil/mud down the hill.Gushing water or accumulated water absorbed by the soil reduces fiction and causes mudslide.Earthquake can also lead to mudslide as it shakes the ground and starts the downward movement of soil.Mudslide harms the trees, plants, vegetation, blocking roads, railway tracks, etc.One of the ways of prevention from mudslides is planting trees and grasses on steep hills. The roots of the plants and trees could grip and hold the soil together which could protect the soil from easily falling down the hill.
