<u>Answer</u>: A heritable trait can be changed from one generation to another.
<u>Explanation</u>:
- The concept of <em>descent with modification</em> was given by Darwin which simply states that the traits are passed on from the parents to the offsprings.
- The traits that can be passed on are known as <em>heritable traits</em>.
- These traits are passed on with the help of the genes.
- So this passing on of traits explains the term <em>descent</em> in this concept. However, there are always chances that these heritable traits can be changed due to environmental factors or due to the process of recombination and thus the term <em>modification</em>.
- So <em>descent with modification</em> means that a<em> heritable trait is passed from parents to offspring but it can be changed from one generation to another.</em>
Answer:
Ok so i will try my best to describe the answers:
1) a convection current is like a boiling pot of soup. the burner heats up the soup on the bottom. hot air always goes up because the molecules become more active, making them space out upward. the hot soup travels up through the center of the pot, and the cold soup up top travels down towards the edges of the pot to replace the hot soup that just moved up. the process keeps on going and going until there is no more heat, or until the burner turns off.
2&3) the sun makes everything warmer, so when the sun touches Earth's surface, it warms up the air around it. as soon as the air warms up, it goes up into the atmosphere, like the pot of soup example. then, cold air from the top moves in to replace the hot air. with so many molecules of air moving at one time, it makes gusts of wind during the movement. when it is really windy, that means that there is a lot of hot air moving up and cold air moving down. when there is no wind, that means that every molecule is where it is supposed to be, not disturbing one another.
I hope this helps :D

Answer:
none of the males or females could be colorblind, assuming that this question is referring to x-linked recessive inheritance patterns.
Explanation:
if it is an x linked recessive trait, then the male's genotype is, with (b) representing colorblindness and (B) representing normal vision. the female, who is h o m o z y g o u s for normal vision, would have the genotype.
It would be impossible for the dad to pass on his colorblind gene to a son, because he can only pass a Y chromosome to the son. and a daughter would get the colorblind gene, but the normal gene donated by the mom would dominate it so the daughter could not actually be colorblind
