Why does using zebrafish as a model organism for genetic testing bring up ethical concerns?

Biology

They are not invertebrates so #1 is out

They are not endangered so #3 is also out

Also the argument that they are similar to humans is weak so I would recomend selecting # 4 because this seems like a reasonable ethical decision

this is just an educated guess though, good luck!

Examine a two-gene cross that follows simple Mendelian inheritance of freckles and eyebrow shape between a woman with genotype M
Brilliant_brown [7]

Answer:

b

Explanation:

First, let us look at the result of crossing the two genotypes Mmpp and mmpp.

Mmpp will give the gametes Mp, Mp, mp, and mp

mmpp will give the gametes mp, mp, mp, and mp

The two sets of gametes can thus be lined up on both axis of the Punnet's square as shown in the attached image.

Genotypes of the offspring: 8 Mmpp and 8 mmpp

<u>Since the two genes follow simple Mendelian inheritance pattern, the 2 genotypes automatically equates to 2 phenotypes in the ratio 1:1.</u>

<em>Hence, the correct option is </em><em>b</em><em>.</em>

Which of the following is true? When a nucleus is separated into its constituent protons and neutrons, the sum of the masses of
Vadim26 [7]

Answer: the sum of the masses of the individual protons and neutrons is less than the mass of the stable Nucleus

Explanation:

Nuclei fission involved bonds breaking with the loss of quantity of Energy by the protons and Neutrons

Remember : e=mc2

Therefore, this breakage of bonds result in loss in masses of p and n.

However, in intact Nucleus the energies of the p and n are trapped in the intact bonds holding them together therefore heavier masses than when broken down.
