A man of unknown genotype has type B blood, his wife has type A blood (also unknown genotype). List ALL the blood types possible

for their children. (you may need to do multiple crosses to consider the different possible genotypes of the parents)
Biology

shtirl [24]3 years ago
5 0

Answer:

AB, aB, Ab

Explanation:

Man has blood type B so could be BB (homozygous dominant) or could be Bb (heterozygous)

Woman has blood type A, so she could be AA (heterozygous dominant) or Aa (heterozygous)

Now, we need to make a separate cross for woman with AA, man with BB and we get children of all AB

Then we can make another cross for genotypes Aa and BB, and we get AB and aB

We can continue this for AA,Bb and for Aa,Bb

kicyunya [14]

Answer:

The correct answer is - option D. Soil erosion.

Explanation:

Soil erosion is a normally happening process that has an impact on all landforms. In common agriculture soil erosion alludes to the removing or disintegration of a field's top layer by the normal physical powers of water  

Running water is the main source of soil erosion since water is plenty of quantity and has great power. Exercises that eliminate vegetation upset the ground, or permit the ground to dry are exercises that expand disintegration.

Thus, the correct answer is - option D. Soil erosion.

In one to three sentences, describe what happens during the reduction stage of the Calvin cycle
Marizza181 [45]

Answer:

  1. ATP and NADPH facilitate the reduction of 6 molecules of 3-PGA  (formed in carbon fixation)to six molecules of the simple sugar glyceraldehyde 3-phosphate (G3P).
  2. In the reduction process ADP and NADPH+ are made, when ATP releases energy and loses its terminal phosphate,  and NADPH loses energy and a hydrogen atom.
  3. ADP and NADPH+ return to the light-dependent reactions for re-use.

Explanation:

Sugar biosynthesis in plants, called photosynthesis produces glucose from the reactants;  it uses energy from sunlight, along with carbon dioxide and water. In chloroplasts, this occurs in the light-dependent and dark reactions. In the light- dependent reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.

In the light-independent reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of CO2 with Ribulose 1,5-bisphosphate (RuBP).  Organic molecules are reduced and RuBP is regenerated.

Tems11 [23]

Answer:

The star could also be said to be 360 Million Million miles from the earth's sun.

Explanation:

A light year equals 9.4607 × 10^{12} km.

This is also approximately 6 Million Million Miles.

If we expressed the answer in miles, then we have to multiply 6 by 60.

This is equals to 360.

Therefore, 60 Light years is approximately 360 Million Million miles.

Cheers!
