A cold front often brings intense weather changes such as thunderstorms while a warm front often brings light rain or drizzle. Why is this the case?

Answers

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

Answers

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.

Which statement correctly distinguishes the functions of proteins from other types of biomolecules?

Answers

Answer:

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).

Explanation:

Callie did a lab during which she investigated the difference in cellular respiration rates between two different types of corn: germinating and non-germinating. A germinating seed is one from which a plant has started to grow. A non-germinating seed is usually dry and a new plant has not yet emerged. The data that she gathered are displayed in the graph. After Callie obtained her original results, she wanted to dig deeper. She determined that the germinating corn seed had utilized 100 molecules of glucose in the first few seconds that she performed the experiment. If these data are accurate, how many carbon dioxide molecules would Callie expect to have been released as a waste during this same amount of time? Explain how you arrived at your answer. The formula for cellular respiration is shown below. C6H12O6 + 6O2 → 6CO2 + 6H2O + energy

This a written question and please keep it at 7th grade level

Answers

Answer:

I might be wrong but im guessing 600

Explanation:

Since there is one molecule of glucose used per 6 molecules of carbon dioxide released, if you have 100 molecules of glucose, then you multiply the carbon dioxide by 100 which is 600. Thats what I would say but I might be wrong.

What is an example of behavioral isolation

Answers

Answer:

Behavioral isolation is demonstrated in species of finches. Their mating calls are distinct yet unique across species.

Explanation:

Mutations arising from errors within gene replication often accumulate within populations, becoming more stable. They may lead to the formation of separate, genetically distinct populations called species. These new species arise via:

allopatric speciationperipatric speciationparapatric speciationand sympatric speciation

Behavioral isolation is an isolating mechanism that is part of sympatric speciation. Here, there are apparent non-physical barriers to prevent mating, and several related species live within a population and gene-flow.  However, reproductive isolation occurs through assortative mating (mate choice based on shared traits) which may lead to heteropatric speciation.

Commonly observed in birds, it involves distinct and unique courtship and mating signals. Mates only respond to those fitting the required behavioral patterns such as a courtship dance, nest building, foraging and songs.

b. To display self-peptides to demonstrate cell health
c. To display self-peptides to maintain self-tolerances
d. To display foreign peptides
e. All of the answers are correct.

Answers

Answer:

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)

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.

What is globalization?

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.

a. Medication is needed to act as a signaling molecule to activate the signal transduction pathway.
b. Medication is needed to allow alternate signaling transduction pathways to control glucose levels.
c. Medication is needed to open channels to allow signaling molecules to enter pancreatic cells.
d. Medication is needed to serve as second messengers to regulate glucose uptake by cells.

Answers

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).

What is Type 1 Diabetes?

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:

Extreme thirstIncreased hungerDry mouthUpset stomach and vomitingFrequent urination

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).
