Abotanist is studying pea plants. one of the pea plants that she is studying is tall and has yellow flowers.

if the tall allele is represented by the letter t and the yellow allele is represented by the letter y, which of the following could be the genotype of the plant that she is studying?

a.) short and green
b.) tall and yellow
c.) ttyy
d.) ttyy

The correct answer is-

C.) TTYY

Genotype corresponds to the genetic makeup of an organism ( presented by gene variants, which are called alleles) that depicts particular morphological characteristic in the organism.

As per the information given in this question, one of the pea plants studied by the botanist is tall ( depicted by T allele ) and has yellow flowers ( depicted by Y allele).

Thus, the genotype of the plant that she is studying would be TTYY.

Therefore, option C) is the right answer.

dont know just give me brainliest

the answer is: the „power stroke“ step.

muscle contraction can be divided into a few steps:

1. the release of ach (acetylcholine) in the synaptic cleft, binding of ach for its receptor and consequently opening of the ca channels.

2. the release of ca, binding of ca for the troponin

3. troponin shifting the tropomyosin, which was blocking the active site on the actin

4. myosin heads attaching to actin by breaking down atp to adp+ pi

5.   formation of the ‘cross-bridge’ on the active site of the actin filament by myosin head

6. “power stroke” -the cross bridge pulls actin, which slides over the myosin

9.     7. the release of adp completes the cross-bridge movement and atp attaches to myosin, breaking the actin-myosin cross bridge.
