What would happen if your heart valves stopped working?

Answers

Answer 1

Answer:

In heart valve disease, one or more of the valves in your heart doesn't work properly. Your heart has four valves that keep blood flowing in the correct direction. In some cases, one or more of the valves don't open or close properly. This can cause the blood flow through your heart to your body to be disrupted.

I WILL GIVE BRAINLIEST Pretend you're riding the bus to school on a very cold and snowy day. List 3 different phases changes you might see along the way.

Answers

If you’re talking about scientific phases you will see
1. precipitation(the snow falling)
2. evaporation(water turning into vapor)
3.melting(snow turning the water)

While riding the bus to school on a very cold and snowy day three different phases changes you might see along the way are mentioned below:

1. precipitation(the snow falling)

2. evaporation(water turning into vapor)

3. melting(snow turning the water)

What is precipitation, evaporation, and melting?

Evaporation is the process in which liquid changes in vapour or gas and it can be easily observed during hot summer days when there is raining and when wet clothes dry in the presence of sunlight. Evaporation is directly proportional to temperature and when rate of evaporation increases the temperature also increases.

Precipitation is the water that is falling from the sky and it occurs when a portion of atmosphere becomes saturated with water vapour.

Melting is the process in which solid is converted into liquid like ice cube converted into liquid water and this is one of the example of melting.

Therefore, the mentioned below are three phases changes :

1. precipitation(the snow falling)

2. evaporation(water turning into vapor)

3. melting(snow turning the water)

A scientist conducted a study of an organism and found that its body cells contained 40 chromosomes. While conducting her observations, the scientist noticed that the cells were undergoing cell division. What difference would the scientist expect to observe between the body cells and the sex cells of the organism as they underwent cell division?
Body cells divide by mitosis for the growth and repair of cells, while sex cells divide by meiosis for sexual reproduction.


Body cells divide by mitosis for sexual reproduction, while sex cells divide by meiosis for the growth and repair of cells.


Body cells divide by meiosis for the growth and repair of cells, while sex cells divide by mitosis for sexual reproduction.


Body cells divide by meiosis for sexual reproduction, while sex cells divide by mitosis for the growth and repair of cells.

Answers

Answer:

The difference that the scientist would expect to see between body cells and sex cells with respect to cell division is that body cells divide by mitosis for the growth and repair of cells, while sex cells divide by meiosis for sexual reproduction.

Explanation:

The behavior of the different cell types with respect to their division depends on the functions that each type has.

Somatic cells are those that define the structure and function of the organism, forming tissues by binding together. The process of mitotic division —to obtain from an original cell two identical daughter cells— is important for the growth, development and repair of an individual's tissues.Sex cells or gametes have half of the chromosomal charge —they divide by meiosis, a reductive cell division— and are involved in the process of sexual reproduction.

    The characteristics described for each cell type explain why the other options are not correct.

Answer:

Body cells divide by mitosis for the growth and repair of cells, while sex cells divide by meiosis for sexual reproduction.

Binding of ________________ to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.

Answers

Answer:

Binding of   ACh (acetylcholine)    to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.

Explanation:

It allows acetylcholine to be released into this synapse when an action potential hits a neuromuscular junction. Acetylcholine attaches to the nicotinic receptors localized on the post-synaptic membrane of the muscle fibre's motor end plate, a specialized region.

Which organelle that plays a central role in the transport of new molecules from inside to outside the cell?

Answers

Answer:

The Golgi apparatus plays a central role in molecular transport after biosynthesis.

Explanation:

Transcription occurs in the nucleus during protein synthesis, followed by translation inside ribosomes. Then, new molecules join the endoplasmic reticulum to be folded and modified. In the Golgi, they are tagged and separated into lysosomes for export outside the cell.

 The Golgi system comprises of several regions known as cisternae; they act as independent microenvironments where products requiring their own unique conditions are converted into new, stable biomolecules.

Answers

Answer:

They were frugivores

Explanation:

Frugivores are animals that mainly eat raw fruits, vegetables, roots, seeds, shoots, etc. Frugivores need to eat diverse fruits and succulent fruit-like vegetables to fulfill their nutritional requirements, although they can supplement this diet with flowers, nectar, small insects, etc. Among their adaptations for fruit consumption, frugivore teeth are clearly distinct, having broad incisors to peel tough fruit rinds. Moreover, these animals generally have long small intestines to digest the fruit.

If a woman has both alleles in her body cells, what will her eggs contain?

Answers

The woman will probably produce eggs which carry the allele for straight hairline and eggs with the allele for widow's peak hairline. There is a 50% chance that an egg will carry either allele.

If a woman has both alleles in her body cells, then her eggs will contain only one of the alleles. This is because during the formation of eggs, a process called meiosis occurs, which randomly separates and distributes the alleles to the daughter cells. Therefore, each egg will contain one of the two alleles that the woman carries.

What is allele ?

An allele is a variant form of a gene that is responsible for the expression of a particular trait or characteristic of an organism.

If a woman has both alleles in her body cells, it means that she is heterozygous for that particular gene. This means that she has two different versions (alleles) of the gene, one inherited from each parent.

During the process of meiosis, which produces eggs, the two alleles will segregate, meaning that each egg will receive only one allele.

The allele that ends up in each egg is random and depends on the particular orientation of chromosomes during meiosis.

So, the woman's eggs will each contain one of the two alleles she carries, and there is a 50% chance that each egg will contain either allele.
