Answer:

C) 3

Explanation:

So the one that has a group of three would be the Passive Transport the first one's effect would be Diffusion and the second and third are both together which will be Facilitated diffusion Hope this helps!

The rate of passive transport depends on the permeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration, and/or osmosis.

Hairpins often form at palindromic sequences in single strands of either RNA or DNA. However, several key features differentiate

JulsSmile [24]

Answer:

Explanation:

B) The pentose in the hairpin adopts only the C-3\' endo pucker conformation.

C) The hairpin adopts a right-handed helix with a diameter of 26 Å .

D) The hairpin contains G:C, A:U, and sometimes G:U base pairs.

DNA and RNA are both nucleic acids. Aside the structural difference of DNA being double stranded and RNA being single stranded, in DNA, the nucleotide bases adenine (A) is paired with thymine (T); while cytosine (C) is paired with guanine (G); howerver in RNA, thymine is replaced with uracil.; thus in RNA, the base pairs are - A:U and G:C

RNA however sometimes take on a dynamic structure, called the wobble case pair where guanine and uracil pair - G:U.

The diameter of RNA is 26 Å, while that of DNA is is 20 Å

The ribose in RNA with a helical structure has a C3’ endo conformation.

A sex linked trait can be defined by which genotypes. Choose all which apply.

attashe74 [19]

Answer:

a. Coded for on the X and Y chromosomes

b. Coded for on the X but not Y chromosome

c. Coded for on the Y but not X chromosome

Explanation:

The X and Y chromosomes are the sex chromosomes as they are involved in sex determination. All the genes that are present on the X and Y chromosomes are inherited along with these chromosomes and therefore, exhibit sex-linked inheritance.

X and Y chromosomes share a homologous region. Therefore, the sex-linked genes are defined as the ones present on both X and Y chromosomes as well as the ones that are present on either X or Y chromosomes.

For example, the gene for hemophilia is present on the X chromosome; but not on the Y chromosome. The SRY gene is present only on the Y chromosome.
