The generally accepted parts of modern cell theory include: All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. Give me brainliest lol

What is a similarity and a difference between the stars Rigel &amp; Betelgeuse?​
xxMikexx [17]

Stars as large as Betelgeuse are very unusual. In contrast, Rigel, the bright, bluish-white star at the southwest corner of Orion, is smaller and much hotter than Betelgeuse. Although Rigel is smaller than Betelgeuse, it is still a super-giant star compared to the sun.

hope this helps ^^

Drag and drop the labels (5) that complete this DNA structure.
Naddik [55]
A) Each DNA nucleotide is made up of a sugar, a phosphate group ... Adenine and thymine are connected by two hydrogen bonds, and cytosine and guanine are ... In the case of RNA, the five-carbon sugar is ribose. DNA is made up of two strands that are twisted around each other to form a right-handed helix, called a double helix. Base-pairing takes place between a purine and pyrimidine: namely, A pairs with T, and G pairs with C. In other words, adenine and thymine are complementary base pairs, and cytosine and guanine are also complementary base pairs. This is the basis for Chargaff’s rule; because of their complementarity, there is as much adenine as thymine in a DNA molecule and as much guanine as cytosine. Adenine and thymine are connected by two hydrogen bonds, and cytosine and guanine are connected by three hydrogen bonds. The two strands are anti-parallel in nature; that is, one strand will have the 3′ carbon of the sugar in the “upward” position, whereas the other strand will have the 5′ carbon in the upward position. The diameter of the DNA double helix is uniform throughout because a purine (two rings) always pairs with a pyrimidine (one ring) and their combined lengths are always equal.

The diploid chromosomal number of a cat is 38. If one of the homologous chromosome pairs does not separate during Meiosis I, how
kow [346]

Answer:

25 and 21

Explanation:

if a homologous pair does not separate, then the homologous pair (when the spindle fibers are dragging it over to the other pole), then that chromosomes DNA will be the exact same as the paternal and maternals' DNA. During Meiosis I, there is the stage where the homologous pairs are lined up and pulled apart (where an exchange tends to happen), but if there pair doesn't mix, then the exact same DNA is duplicated, and thus, the same traits can be found in the daughter cell. If you are talking about an entire homologous pair being pulled over to one side of the nucleus, depriving the other side of a chromosomal pair, the daughter cells would then have 21 chromosomes, and the other one would have 25 chromosomes. The gametes, similarly, would have 21 chromosomes and 25 chromosomes.
