Two genes interact to produce various phenotypic ratios among F2 progeny of a dihybrid cross. Design a different pathway explaining each of the F2 ratios below, using hypothetical genes R and T and assuming that the dominant allele at each locus catalyzes a different reaction or performs an action leading to pigment production. The recessive allele at each locus is null (loss-of-function). Begin each pathway with a colorless precursor that produces a white or albino phenotype if it is unmodified. The ratios are for F2 progeny produced by crossing wild-type F1 organisms with the genotype RrTt.
9/16 Dark Blue 6/16 light blue 1/16 white
A) At least one copy of each dominant allele results in dark blue, at least one copy of either dominant allele produces light blue, and the absence of both dominant allele produces white.
B) If both dominant alleles are present, the result is dark blue. At least one copy of one specific dominant allele is required for light blue. If that dominant allele is not present, the result is white, regardless of whether the other dominant allele is present.
C) At least one copy of both dominant alleles results in dark blue; at least one copy of one of the dominant alleles also results in dark blue, but at least one copy of the other dominant allele produces light blue; and the absence of either dominant allele produces white.
Answer:
The correct option is A) At least one copy of each dominant allele results in dark blue, at least one copy of either dominant allele produces light blue, and the absence of both dominant allele produces white.

Answer:
Most likely a dog and a turtle.
Explanation:
A Dog and a Turtle organisms do you think might be more closely related to each other, So, the correct option is A.
What is an organism?An organism is defined as any living system which functions as an individual unit where all living things are made up of cells. The concept of organism is based on the concept of the minimum functional unit of life.
Biological organisms are defined as living things capable of responding to stimuli, reproduction, development and homeostasis which are classified by taxonomy into specified groups such as multicellular animals, plants and fungi; or unicellular microorganisms such as protists, bacteria and archaea.
A Dog and a Turtle organisms do you think might be more closely related to each other as both have four legs and belongs to Phylum Chordata.

how does the simple cuboidal epithelium do its function
Answer:
Diagram of simple cuboidal epithelium. By lining the surface of various ducts of various glands and organs, simple cuboidal cells are able to provide a layer of protection from abrasion, foreign particles, invading bacteria and excessive water loss (due to its selective permeability) to the underlying tissue.
Explanation:
Answer:
Simple cuboidal epithelium consists of a single layer cells that are as tall as they are wide. The important functions of the simple cuboidal epithelium are secretion and absorption. This epithelial type is found in the small collecting ducts of the kidneys, pancreas, and salivary glands.
1.Compare and contrast a cold and warm front.
2. Along which type of front is the weather the calmest? Justify your answer.
Answer:
A cold weather front is defined as the changeover region where a cold air mass is replacing a warmer air mass. Cold weather fronts usually move from northwest to southeast. ... Warm fronts usually move from southwest to northeast and the air behind a warm front is warmer and moister than the air ahead of it.
ExplanationThere are four different types of weather fronts: cold fronts, warm fronts, stationary fronts, and occluded fronts. the direction of flow of the air mass and its characteristics. so based on what we know i would say that warm fronts are calmest

Which of the following statements about the flow of energy in nature is not true?
A. A large amount of energy in food is needed for bodily function
B. A major portion of the energy from food is used to keep our bodies warm
Only a small portion of the energy from food is used to keep our bodies warm or for other bodily functions. Most of it is lost as heat or through other processes.
When answering questions on Brainly, it is important to always be factually accurate, professional, and friendly. It is also important to be concise and avoid providing extraneous details, while also taking care to address all parts of the question.
Typos and irrelevant information should not be ignored. In the case of the provided question, the answer is option B: A major portion of the energy from food is used to keep our bodies warm. This is not true in the context of the flow of energy in nature.
The flow of energy in nature involves a constant transfer of energy from one organism to another in an ecosystem. Energy enters an ecosystem through primary producers like plants, who convert sunlight into food through photosynthesis.
This energy is then transferred to herbivores, who are then eaten by carnivores. As energy flows through the food chain, only a small amount of energy is transferred from one trophic level to the next.
The majority of the energy is lost through respiration, heat loss, and other metabolic processes.

Why couldn't yeast use both sugar and artificial sweetener for cell respiration?
Yeast couldn't use both sugar and artificial sweetener for cell respiration because of the low calorie content of artificial sweetener.
What is artificial sweetener?Chemicals called artificial sweetening agents are used to sweeten food. They do not, however, provide our bodies with extra calories.Which one will have better yield?The sugars will have better yield because natural sugars like sucrose have more calories than artificial sugars.This increased energy will allow the yeast to metabolize faster and hence more carbon-dioxide is released.What is cellular respiration?"Cellular respiration is a series of metabolic processes that take place inside of cells to transform biochemical energy from food into a compound called as adenosine triphosphate (ATP)."
