In Indian cuisine, sometimes a papaya is added to make meat cook faster. Which of the following is a plausible explanation of wh

y this method speeds the chemical changes that occur during cooking?
A: Enzymes in the papaya absorb energy from the meat's molecules, thereby increasing the temperature of the meat and hastening the cooking process.

B: Papaya contains the enzyme papain, which breaks down some of the meat's proteins, thereby hastening the cooking process.

C: Papaya contains the enzyme papain, which strengthens the bonds among the meat's proteins, thereby hastening the cooking process.

A is the answer because it refers to the enzymes in the papaya not what the enzyme is called.

In guinea pigs, brown coat color allele (B) is dominant over red (b), and the solid color allele (S) is dominant over the spotte
Valentin [98]

Answer:

<h2>3/16</h2>

Explanation:

As given;

Brown coat color (B) is dominant over (b), so B is dominant over b.

Solid color (S) is dominant over the spotted(s), so S is dominant over s.

crossing between true breeding brown, solid colored guinea pig( BBSS) with red spotted pig( bbss)

so parents are  BBSS× bbss

gametes are, of parent-1; BS, and parent-2: bs

F1 is : BbSs,

cross between F1 and F1

F2 is : BBSS, BBSs, BbSS, BbSs............BBss..........Bbss........bbSS.......bbss etc

So red and solid color offspring are (bbS_) = 3/16

Which of the following statements about the meiosis are correct? Select all that apply. Select all that apply. Sister chromatids
pychu [463]

Answer:

  • Sister chromatids are not homologous chromosomes.
  • Crossing over occurs between non-sister chromatids.

Explanation:

  1. "<em>Sister chromatids are not homologous chromosomes</em>". IT APPLIES.
  • One chromatid is a chromatin strand that got thick after folding.  The chromatin strand is the DNI double helix associated with histones.  Before cellular division, the chromatin strand generates a copy or clon, so both of the daughter cells can get the same genetic information. These two strands keep joint together by a centromere. The chromosome is conformed by the chromatin strand and its copy, condensated and joint by the centromere. It looks X-shaped.  The chromatin strand and its clon are known as sister chromatids, and they are together on the same chromosome. So one chromosome is composed of two chromatids.
  • Homologous chromosomes are those that give information for the same trait, but this information is not necessarily the same. For example, both homologous chromosomes might give information for hair color trait, but one of them gives information for brown hair and the other one gives information for black hair.

2. "<em>Crossing over occurs between non-sister chromatids"</em>. IT APPLIES.

  • Crossing-over occurs <u>between two homologous chromosomes</u> in the equatorial plane, that makes the daughter cells to be genetically different from the original one.  

3.  "Sister chromatids are found on two different homologs". IT DOES NOT APPLY.

  • The chromatin strand and its clon, known as sister chromatids, are together on the same chromosome. <u>So one chromosome is composed of two chromatids. </u>

4. <em>"A chiasma forms between four molecules of double-stranded DNA on duplicated homologous chromosomes". </em>IT DOES NOT APPLY

  • Chiasma is the point where two chromatids interchange genetic information making a place to new genetic material or information that will be inherited to descendants. Chiasma allows the crossing-over between <u>two homologous chromatids</u>, one of each parent.
