The last time you saw the sisters pictured above, you considered how different protein molecules in their cells could lead to di

fferent traits. Now, you know that genes provide instructions for proteins that lead to traits. How could these sisters have ended up with different genes, leading to their different proteins and traits? Explain your ideas below.​

Answer:

recombination and independent segregation of chromosomes during meiosis  

Explanation:

Recombination and independent segregation of chromosomes represent the two most important meiotic mechanisms by which sisters from the same parents can inherit different gene variants and therefore look very different from each other:  

1- Independent assortment (segregation) of chromosomes: during meiosis, homologous chromosomes are randomly distributed in daughter cells (which will give rise to the gametes), and therefore separate independently of each other. It is for that reason that gametes have unique combinations of chromosomes, which increases genetic variation.

2- Recombination, also known as crossing over, refers to the exchange of chromosome segments between non-sister chromatids during meiosis. This mechanism is well-known to produce new gene variants (alleles) in the daughter cells. In consequence, recombination also increases the genetic variation of the resulting gametes that will produce offspring (in this case, different sisters).

Answer:

I believe the first one would be incomplete dominance, the second would be multiple alleles, and the third would be codominance.

Explanation:

The first one would be incomplete dominance because the child has a blend of the man's straight hair and the woman's curly hair, but neither of two hair types are completely dominant (if that makes sense).

The second one would be multiple alleles because, well, there are multiple alleles listed (more straightforward than the other two).

And the third one would be codominance because the traits of red color and white color are equally dominant.

What type of stellar object will the sun end its life end
Lerok [7]
Your wording is a bit confusing, but I get what you're trying to say.

Here's what the life cycle of a star looks like.

Stars begin as giant balls of hydrogen colliding together and releasing a ton of energy. This hydrogen will eventually fuse together to form helium, and once all of the hydrogen has become helium, This helium will, after a very long time and under lots and lots of pressure, form carbon. When this happens, it is considered a red giant, and the star becomes bigger and less bright. The star will become less and less bright and eventually start to shrink as all of that carbon turns to heavier elements like iron, turning into a dwarf star that eventually dies out.
(Dwarf stars are still shining are called white dwarf stars, and dead ones are black)

The cool part, though, is that massive stars (those which have a mass of at least 3 times the Sun's) turn into heavy elements so fast that the core collapses almost instantaneously and explodes violently into a ball of fire known as a supernova.

Sometimes the core of the star gets left behind, and either forms a neutron star or, if it has the mass of a massive star, will collapse in on itself and become a black hole.

The distribution of water between intra- and extra-cellular spaces depends on concentration differences of _____, or dissolved s
Aleks04 [339]

Answer:

Solutes

Explanation:

According to my research on studies conducted by various chemists, I can say that based on the information provided within the question this depends on concentration differences of Solutes. This although already defined in the question, is the minor component in a solution, it is the component that gets dissolved in the solvent.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
