A horticulturalist wants to produce geraniums with specific characteristics. She knows that the trait of red flowers is governed
likoan [24]
<span>The answer is  A -The red geranium is heterozygous for red flowers (Rr).

We know that the red flower, to be red needs to have at least a dominant allele, so it could be either Rr or RR.
Let's try both scenarios.
If the white</span><span> geranium (rr) is being crossed with RR, all the offspring would be red with genotype: Rr.
On the other hand, if the flower is Rr and it's being crossed with rr, that would result in </span><span>half of the new generation plants having red flowers and the other half white flowers.</span>

stellarik [79]

The purpose of MHC molecules is to bind and display pathogen-derived peptide fragments on the cell surface so that the relevant T lymphocytes can recognise them.

<h3>What are MHC proteins, or major histocompatibility complex proteins?</h3>

MHC, or the major histocompatibility complex, is a set of genes that produce proteins located on the cell surfaces and that aid the immune system in identifying foreign objects. In all higher vertebrates, MHC proteins are present. The complex in humans is also known as the HLA (human leukocyte antigen) system.

<h3>What exactly are MHC proteins, and why are they crucial?</h3>

The major histocompatibility complex (MHC) is a collection of genes that code for cell surface proteins that play a significant part in the immune response. MHC molecules have a major role in how they display antigens.

Imagine that a biologist deposits 50 isopods on the surface of the leaf litter in a forest. the back ofeach isopod is marked wit
zhannawk [14.2K]

Answer:

The isopods will be found under the leaf litter.

Explanation:

Isopods are crustaceans and they live in freshwater, marine water or on land. The forms of isopods that are found on land mostly prefer the cool and moist environment.

As the biologist will leave them on leaf litter, they will crawl to the area under the leaf because the area under the leaf litter is relatively cool and moist and there they can get an environment which is suitable for their living. Thus when the biologist will come after one hour, most of the isopods will be found under the leaf litter.
