In C4 plants such as corn and sugarcane, carbon fixation takes place in the _________ cells, and then the CO2 is transferred as
Zarrin [17]

Answer:

Mesophyll and bundle sheath cell.

Explanation:

C4 pathway is also known as hatch slack pathway it is a photosynthetic process in some plants. In this pathway carbon is extracting from carbon dioxide to able to use in sugar and other biomolecules. C4 is known as four carbon molecules which is the 1st product of this type of carbon fixation.

In this pathway rubisco enzyme works in the environment where lots of carbon dioxide and very little oxygen present. CO2 is transferred via malate or aspartate from mesophyll cells to bundle sheath cells. In bundle sheath cell CO2 is released by malate decarboxylation.

C4 plants use PEP carboxylase to absorb more amount of CO2 in the mesophyll cells. Phosphophenolpyruvate (PEP) which is 3 carbon molecule binds with CO2 and make oxaloacetic acid, it forms than malate, 4carbon molecule. Malate enters through a plasmodesmata into bundle sheath cell and release the CO2.

Assume in otters short hair (L) is dominant to long hair (l) and black hair (B) is dominant to brown (b). If you found a black s
Georgia [21]

Answer:

llbb

Explanation:

<em>The genotype of the black, short-haired otter could be determined by testing-crossing with a brown, long-haired otter whose genotype would be </em><em>llbb</em><em>.</em>

Analysis of the resulting zygote from the cross would give an indication of the genotype of the otter - whether it has two dominant alleles each for the black, short-hair traits or heterozygous.

<u>If the otter has two dominant alleles for the two traits, all the resulting zygote from the test-cross would have black, short-hair, but if it is heterozygous, a mixed phenotype set of zygote would be obtained.</u>
