2. write a sentence that describes how the food changes in the small intestine.
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.
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!

What are the phenotypic ratios of a white-eyed female is crossed with a red-eyed male
Answer:
We need to cross a white eyed female (XwXw) and red eyed male (XRY).
The cross can be shown as:
Xw Xw
XR XRXw (female, red eyed) XRXw (female, red eyed)
Y XwY (male, white eyed) XwY (male, white eyed)
Thus, in the offspring we will have the following phenotype:
Males: White eyed.
Females: Red eyed.

Which of these steps would help to reduce the chances of a mudslide occurring in a hilly region?
A
leaving the trees and other plant cover on the hillsides
B
removing all trees and plant cover from the hillsides
C
building fences at the bases of the hills
Answer:
Option A. Leaving the trees and other plant cover on the hillsides.
Explanation:
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.For more information:

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.
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

Answer:
I think it's C. it's sexual reproduction because the sperm and egg is comming from two different salamanders, not the same one. Since the egg and sperm are from different salamanders then there will be genetic variation in the offspring because the DNA from two different salamanders are present in the offspring.
Which of the following pieces of evidence supports the theory of plate tectonics?
A
the size and shape of Earth
B
the composition of Earth's layers
C
tectonic plates observed from satellite images
D
similar mountain ranges found on different continents
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.
