That a Tt heterozygous, giant plant produces T and t gametes with equal probabilities whereas a Tt homozygous, narrow plant exclusively produces t gametes, their offspring 50% tall and 50% short are crossed.

The term "heterozygous" describes the presence of several alleles for a given trait. You have a dominant gene for that gene if the versions differ from one another. Which qualities are expressed depends on how the two genes are related.

You have a genetic mutation for that gene if the variants differ from one another. For instance, having one gene for red hair but one allele with brown hair could indicate that you are heterogeneous for hair color. Which qualities are expressed depends on how the two alleles are related.

Answer: Your answer is option (A).

Explanation:

Hyperventilation decreases the respiratory rate by decreasing the levels of carbon dioxide in the blood, which leads to a decrease in the drive to breathe.

The number of breaths you take each minute is referred to as your respiratory rate. Adults typically breathe 12 to 20 times per minute while at rest. When resting, an abnormal respiration rate is one that is less than 12 or greater than 25 breaths per minute.

Hyperventilation leads to a decrease in the drive to breathe. This is because the primary stimulus for breathing is the buildup of carbon dioxide in the body. When carbon dioxide levels drop, the body's natural drive to breathe also decreases, resulting in a slower respiratory rate.

The bird represents Mrs. Wright's loneliness during her marriage to Mr. Wright.

Susan Glaspell's Trifles is a one-act drama. On August 8, 1916, the Provincetown Players staged it at the Wharf Theatre in Provincetown, Massachusetts. Glaspell portrayed Mrs. Hale in the original production. The drama is regularly anthologized in textbooks of American literature. The play, written during the first wave feminist movement, contrasts how women act in public and in private, as well as how they perform in front of other women vs males.

Through the absence of its main character, Mrs. Wright, Trifles addresses the issue of identity. Glaspell reveals how a person's identity is "just as much created as innate" by leaving this figure off stage. Mrs. Wright can only be perceived by the audience via the lens of the on-stage characters as they review and debate her personal life and alleged crime, and these characters may not all perceive Mrs. Wright in the same way. The spectator gets a well-rounded image of Mrs. Wright and how her identity is flexible and evolves based on the preconceptions of the other characters from the group in the farmhouse.

Explanation:

When light strikes a leaf, it can be absorbed by, reflected from or transmitted through the leaf. Plants appear green because they reflect and transmit slightly more green light than they do blue or red light. Chlorophyll also absorbs green light poorly. For these reasons, green light is sometimes stated as not being useful to plants for photosynthesis. However, green light is still moderately effective since other pigments absorb the light and make it useful for photosynthesis. A more correct statement is that, generally, green light is less efficient at stimulating photosynthesis than blue or red light. In some situations, the greater reflection and transmittance of green light by leaves can be desirable. Green light can better penetrate a plant canopy and thus reach lower leaves. This can, in theory at least, reduce lower-leaf loss. However, few LED arrays contain green LEDs because they are less efficient than blue and red LEDs from both an electrical and plant response perspective.
