On a scratch sheet of paper, complete the Punnett square of the cross between two heterozygous red-eyed flies (Rr). What color eyes will the offspring have?

Answers

Answer 1

Answer:

75% red, 25% other color (brown?)

Explanation:

A cross between two heterozygous red eye flies (Rr x Rr)

                     R                     r

R                  RR                   Rr

r                   Rr                   rr

The possible genotypes are RR, Rr, and rr. There are two possibilities of Rr.

Since the heterozygotes have red eyes, the red eye allele must be dominant. Therefore, RR and Rr genotypes will all have red eyes. That means 3/4 (75%) of offspring will have red eyes. 1/4 25% are h0m0zygous recessive (rr), and will therefore have the other eye color (question doesn't mention which colour this is, it is likely brown)

Conduct online research to learn more about competition between two species not mentioned in this lesson. Make sure to include information about their niches, common resources, and other competitors.

Answers

Answer:

In many forest ecosystems, squirrels and chipmunks compete for acorns and some other resources. However, they don’t have the exact same niches. Squirrels nest in trees, while chipmunks live underground. These species don’t compete with each other for mates either. Thus, squirrels are in interspecific competition with chipmunks.

All squirrels in a particular ecosystem share the same niche. The same is true of all chipmunks. So, both of these species are in intraspecific competition. Competing with an individual from the same species is harder than competing with members of other species. For example, squirrels compete with other squirrels for not only food (acorns), but also shelter and mates. However, they also compete with some other species, such as deer and acorn weevils, for acorns. Furthermore, they are both prey for many of the same predators, such as hawks, raccoons, foxes, and weasels.

What is the use of reverse transcriptase?

Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.

Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and  DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.

The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.

Therefore, The mRNA sequence will best match the section of DNA shown below is  C-U-A-G-G-A. Thus, option C is correct.

When glucose, a 6-carbon sugar, is broken down during glycolysis, what product forms?

Answers

Answer:

pyruvate

Explanation:

In glycolysis, the 6-carbon sugar, which is glucose, is broken down into two molecules of a 3-carbon molecule called pyruvate.

During glycolysis, glucose is broken down into ; Pyruvate molecules  and energy

Glycolysis is a cytoplasmic process during which glucose is broken down into two  3 carbon compounds ( pyruvate ) and energy is generated from t glucose in the process.

Answers

Explanation:

it is systematic desensitization.

Creating a list of anxiety-triggering situations and training in relaxation are important aspects of SYSTEMATIC DESENSITIZATION.

Systematic desensitization is a type of therapy based on the combination of relaxation methods with gradual exposure to the fear (phobia).

The objective of the exposure to the fear is that the patient feels progressively less anxious about his/her phobia.

In consequence, systematic desensitization increases the feeling of self-control and gradually reduces fear.

In conclusion, creating a list of anxiety-triggering situations and training in relaxation are important aspects of SYSTEMATIC DESENSITIZATION.

Answers

Answer:

A sudden increase in the pressure inside a person's skull is a medical emergency. Left untreated, an increase in the intracranial pressure (ICP) may lead to brain injury, seizure, coma, stroke, or death. With prompt treatment, it is possible for people with increased ICP to make a full recovery

Explanation:

A medical emergency occurs when a person's internal pressure suddenly increases. An increase in intracranial pressure (ICP) may cause brain damage, seizures, comas, strokes, or even death if left untreated.

What is brain?

The brain is a sophisticated organ that manages every bodily function as well as thought, memory, emotion, touch, motor skills, vision, respiration, temperature, and hunger. The central nervous system, or CNS, is made up of the spinal cord that emerges from the brain.

There are two distinct parts of the central nervous system: gray matter and white matter. Gray matter in the brain refers to the thicker, outer layer, and white matter to the thinner, inner layer beneath.

It is possible for patients with elevated ICP to fully recover with prompt treatment.
