In the proto-solar system nebula, gravity pulled matter together to form larger bodies. As they collided, what happened to these
Karolina [17]

Answer:

There was a release of immense heat within the bodies as they collided together as gravitational potential energy was converted into kinetic energy of the individual gas particles and then collisions between these particles converted this energy into heat.

Therefore, a massive amount of heat was released.

During the process of cellular respiration, one molecule of glucose is capable of producing up to 32 molecules of ATP. Explain t
xxTIMURxx [149]
<span>The protons want to diffuse into the mitochondrial matrix and they do this by going through the ATP synthase protein which resembles a water turbine. As the protons move through the ATP synthase, ATP is produced. In essence the energy from H+ wanting to diffuse through the inner mitochondrial membrane is converted to energy in the form of ATP</span>

Describe the basic components of<br> DNA (deoxyribonucleic acid).
Reika [66]

Answer:

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

Barred feather pattern is a Z-linked dominant trait in chickens. What offspring would you expect from (a) the cross of a barred
Bezzdna [24]

Answer:

Let the "barred" allele be caller B and the "non-white" allele b. Since chickens use chromosomes Z  and W to determine sex, hens would have chromosomes ZW, and roosters would have chromosomes ZZ. A Z-linked gene is represented as a superscript on the Z chromosome, Z^{B} for the dominant allele and Z^{b} for the ressesive allele.

A barred hen would have a copy of B on its Z chromosome, a non-barred rooster would have both copies of b on both Z chromosomes. Using Punnet squares to represent the crosses we get the following cases:

\begin{center}\begin{tabular}{ |c|c|c|c| }\ & Z^{B} & W \\ \ Z^{b} & Z^{B}Z^{b} & Z^{b}W \\ \ Z^{b} & Z^{B}Z^{b} & Z^{b}W \\ \end{tabular}\end{center}

That is a ratio of two barred heterozygote roosters to two non-barred hens. Crossing them we get:

\begin{center}\begin{tabular}{ |c|c|c|c| }\ & Z^{b} & W \\ \ Z^{B} & Z^{B}Z^{b} & Z^{B}W \\ \ Z^{b} & Z^{b}Z^{b} & Z^{b}W \\ \end{tabular}\end{center}

That is a ratio of one barred heterozygote rooster to one barred hen to one non-barred rooster to one non barred hen.
