Answer:

Hydrogen

Explanation:

hydrogen couldn't form until the universe had cooled enough to allow their nuclei to capture electrons, about 380,000 years after the Big Bang, Within about 3 minutes after the Big Bang, conditions cooled enough for these protons and neutrons to form hydrogen nuclei.

The following F2 phenotypic data was obtained from a Drosophila testcross using an F1 offspring. Assume red eye and brown body a

dmitriy555 [2]

Answer:

The genotype of the F1 was wy+/w+y.

Explanation:

One of the given options has a typo: the red eye-brown body offspring count should be 56 instead of 561.

We have two genes with two alleles each:

Red eyes (w+) is dominant over white eyes (w).

Brown body (y+) is dominant over yellow body (y).

The phenotypes of the F2 tesulting from a test cross (F1 x wy/wy) are:

wy+/ey (white-eye, brown body): 670
w+y/wy (red-eye, yellow body): 650
wy/wy (white-eye, yellow body): 38
w+y+/wy (red-eye, brown body 56

If the genes w and y are linked, two phenotypes in the F2 will be much more abundant than the other two. Recombination during meiosis is a rare event, so the most abundant phenotypes are the parentals (the ones present in the F1 parent).

Every individual in the offpsring has a wy chromosome, as this was the gamete inherited from the test cross individual.

In this case, the most abundant gametes are wy+ and w+y, so the genotype of the F1 was wy+/w+y.

Notice how when recombination occurs in the F1 parent, the recombinant gametes appear: wy and w+y+, which are the less abundant in the F2 progeny.

A particular protein largely lacks both secondary and tertiary structure. which factor, if any, is mainly responsible for the re

NemiM [27]

Entropy, is mainly responsible for the resting state of this protein.

Hydrogen bonds, disulfide bonds, and dipole-dipole interactions produce the complicated folding styles seen in secondary and tertiary structure. however, if a protein does not have these elements of structure, it'll undertake a kingdom in which its entropy is maximized.

Secondary shape is determined through hydrogen bonding within the amino acid chain backbone. Tertiary structure is the entire protein's form, decided Entropy Interplay and hydrophobic forces. The tertiary shape of a protein is the 3 dimensional shape of the protein. Disulfide bonds, hydrogen bonds, ionic bonds, and hydrophobic interactions all affect the form a protein takes.

The nonpolar amino acids have formed the nonpolar center of the protein, weak van der Waals forces stabilize the protein. furthermore, hydrogen bonds and ionic interactions between the polar, charged amino acids make a contribution to the tertiary structure.

Disclaimer: your question is incomplete, please see below for complete question

A. Entropy

B. Hydrogen bonds between amino acid residues

C. Dipole-dipole interactions

D. None of the above
