In plants tall (T) is dominant to short (t) and round seed is dominant to wrinkled seeds (r). If a parent is short and wrinkled

Nuetrik [128]

Answer:

Parent cross= ttrr (short, wrinkled) × TtRr (hybrid)

POSSIBLE GAMETES BY EACH PARENT:

ttrr - tr, tr, tr, and tr

TtRr - TR, Tr, tR, and tr

Explanation:

This question involves two genes in a certain plant. One gene is coding for height while the other is coding for seed shape. The alleles for tallness (T) and round seeds (R) is dominant over the alleles for shortness (t) and wrinkled seeds (r).

According to this question, a parent that is short and wrinkled (ttrr) is crossed with another parent that is hybrid (TtRr) for both traits. This means that the parent cross is as follows: ttrr × TtRr

The possible combination of gametes that will be produced by each parent is as follows:

ttrr - tr, tr, tr, and tr

TtRr - TR, Tr, tR, and tr

See attached image for the punnet square using these gametes.

Oliga [24]

Answer:

The correct answer will be- lesioning

Explanation:

Lesioning is a technique used to treat severe movement disorders related to Parkinson's disease.

In lesioning, the lesions (damage) are created in a small part of the brain related to the movement by sending an electric current through a thin insulated wire.

This technique nowadays used in research centres to study the different parts of the brains to study the functions related to the brain.

Thus, lesioning is the correct answer.

HELP ASAP I WILL GIVE BRAINLIST!!! Read the given chemical reaction.

daser333 [38]

Answer:

4.2moles

Explanation:

"The answer to your question is 4.2 moles of H₂O

Explanation:

Data

moles of H₂O = ?

moles of C₂H₆ = 1.4

Balanced chemical reaction

2C₂H₆ + 7O₂ ⇒ 4CO₂ + 6H₂O

Process

To determine the moles of H₂O, use proportions and the coefficients of the balanced chemical reaction.

2 moles of C₂H₆ 6 moles of H₂O

1.4 moles of C₂H₆ x

x = (1.4 x 6) / 2

x = 8.4/2

x = 4.2 moles of H₂O"
