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. Which statement is correct? 12/16 white: 3/16 green: 1/16 yellowA) At least one copy of both dominant alleles results in white; at least one copy of one of the dominant alleles also results in white, but at least one copy of the other dominant allele produces green; and the absence of either dominant allele produces yellow.B) If both dominant alleles are present, the result is green. At least one copy of one specific dominant allele is required for yellow. 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 each dominant allele results in white, at least one copy of either dominant allele produces green, and the absence of either dominant allele produces yellow.

Answer:

The front term is associated with an area where two air masses met and as it is usually the condition with heavy rain, fierce wind, snow and other violent weather like a war situation. The front could be warm, cold, occluded or stationary depends on the type of weather.

The cold front is associated with lots of thunderstorms and other intense weather while the warm front changes with drizzly rain and warmer weather due to the fact that in a cold front, replacement of warm air by the cold air is faster while in a warm front, the replacement of cold air by warm air is gradual

Answer:

removing wastes from the body

Explanation:

Excretory system is one of the organ systems in our body. The excretory system encompasses all the organs in the body associated with the function of REMOVING WASTES FROM THE BODY, which represents the primary function of the excretory system.

These organs in the excretory system which include; kidney, skin, lungs etc. all functions to remove one waste or the other. For example, the kidney removes URINE, the skin removes SWEAT, the lungs remove C02.

e. All of the answers are correct.

Explanation:

The major histocompatibility complex (MHC) is a locus that contains several polymorphic genes. These genes are known to encode different components of the immune system, especially cell-surface proteins which present antigens to the T cell receptors during adaptive immune responses. The MHC genes are classified into Class I, Class II and Class III:

1- MHC class I genes encode cell surface molecules that present peptides (antigens) to cytotoxic T lymphocytes (i.e., killer T cells)

2- MHC class II genes encode cell surface molecules that present antigens to CD4+ T cells

3- MHC class III genes encode proteins that are not involved in antigen presentation (i.e., components of the complement cascade, cytokines, etc)

Answer: Unlike leading strands, lagging strands are synthesized as discrete short DNA fragments, termed 'Okazaki fragments' which are later joined to form continuous duplex DNA. Synthesis of an Okazaki fragment begins with a primer RNA-DNA made by polymerase (Pol) α-primase.

Answer:

The correct answer is - option. b climbing a rope hand over hand is correct

Explanation:

The movement of the kinesin molecules led by the head of one kinesin followed by the second one after another same as one hand moves on the rope at a time and followed by the other hand during climbing the rope.

The movement of the kinesin microfilament is due to the increased affinity by ATP of the head of the kinesin for the microtubule. However, the hydrolysis of ATP decreases its affinity so it slides or moves to the plus end.

Answer:

A. An Italian fashion company has its clothes made in Taiwan

Explanation:

Globalization is when a company starts having influence in other countries. This is bet seen in A. The fashion company is able to sell it's clothes all over the world. But, it's based in Italy. That is already globalization. But, on top of that, to have it made in Taiwan if even more foreign influence.

The situation best illustrates globalization's effect on an economy is An Italian fashion company has its clothes made in Taiwan. The correct option is A.

Globalization means when the economy or trade is happening and connects with the world. The trade that makes the world interconnected, then it is called globalization.

An Italian company when established its fashion company in Taiwan, creates a relationship between these two countries, and increases globalization.

All other options show trading or manufacturing in the local markets, within the states or countries, doesn't match with the term globalization.

Thus, the correct option is A. An Italian fashion company has its clothes made in Taiwan.

This question is incomplete

Explanation:

This question is incomplete. However, the four major biomolecules have the following different functions

1) Nucleic acid (as in DNA and RNA): They are a sequence of nucleotides that store organism's genetic code. This nucleotide sequence in turn determines an organism's protein sequence.

2) Carbohydrates: They are important structural components of various "compositions" in an organism (such as the cellulose in cell wall and ribose in nucleotide). They also serve as energy sources for the body.

3) Lipids: They also serve as energy sources and are part of membrane composition (as in the case of the phospholipid cell membrane).

4) Proteins: They are major structural elements of cells. They serve as enzymes in many biological activity (such as hexokinase in glycolysis and DNA polymerase in DNA replication). They also form hormones (such as insulin) and antibodies (such as the Immunoglobulins).

Answer:

the answer is a. Medication is needed to act as a signaling molecule to activate the signal transduction pathway.

i took the quiz

Medication is needed to act as a signaling molecule to activate the signal transduction pathway. So, the correct option is (A).

Type 1 diabetes also called insulin-dependent or juvenile diabetes which is usually develops in children, adolescents, and young adults, but it can occur at any age. A condition in which the immune system destroys the insulin-producing cells in the pancreas. These are called beta cells.

There are several signs of type 1 Diabetes which include:

When a person suffering from this disease needs medication which is need to act as signaling molecule to activate the signal transduction pathway. Type 1 Diabetes is characterized by a progressive loss of insulin-producing β-cells in the islets of the pancreas. Immune destruction of β-cells is partly mediated by high levels of pro-inflammatory cytokines.

Thus, medication is needed to act as a signaling molecule to activate the signal transduction pathway. So, the correct option is (A).

Explanation:

A prokaryotic cell is a type of cell that does not have a true nucleus or membrane-bound organelles. Organisms within the domains Bacteria and Archaea are based on the prokaryotic cell, while all other forms of life are eukaryotic

A prokaryotic is a primitive cell that lacks organelles, unlike the eukaryotic cells, and are simple organisms.

Prokaryotes are organisms that are simple and evolved before the complex eukaryote. They include bacteria and archaea that are simple and lack organelles that are found in eukaryotes.

They do not have a nucleus and rather have their genetic material disposed of as nucleoids in the center of the cell that undergoes the simple process of the central dogma.

The simple cellular processes and reproductive methods are the reason they lack many organelles. This tells that prokaryotes are simple and primitive types of cells.

Therefore, prokaryotes lack a distinct nucleus.
