Which statement explains why ammonites are a good example of an index fossil?

Answers

Answer 1

Answer:

Ammonites existed only in the oceans.

Explanation:

Index fossils serve as a relative dating marker for geologic time periods and the rocks formed at those times. The fossils are of species that lived for only a short while, though that could be millions of years, and were widespread on the Earth. Ammonites are good index fossils for several reasons. First, they are easily identified by their spiral shells.

The primary purpose of the ______ circuit is for the blood to release carbon dioxide and pick up oxygen.

Answers

Answer:

Explanation:

The  primary purpose of the  systemic  circuit is for blood to release carbon dioxide and pick up oxygen

The primary purpose of the pulmonary circuit is for the blood to release carbon dioxide and pick up oxygen.

What is pulmonary system?

It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs.

Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.

The respiratory system makes it possible for the body to take in oxygen and expel carbon dioxide.

The nose and mouth are the beginning of the respiratory system, which continues through the airways and lungs.

The pulmonary circulation serves a variety of crucial purposes. Its main job is to exchange gases across the alveolar membrane.

This ultimately results in oxygenated blood being delivered to the rest of the body and carbon dioxide being removed from the bloodstream.

Thus, the pulmonary circuit's main function is to allow the blood to absorb oxygen and release carbon dioxide.

As a result of higher osmotic gradient outside, ____________ moves out of the thin descending limb of Loop of Henle

Answers

Answer:

is it water?

Explanation:

As a result of higher osmotic gradient outside, water moves out of the thin descending limb of Loop of Henle.

What is osmotic potential?

Osmotic potential is a component of water potential whose magnitude depends on the amount of solutes present in the solution, with osmotic pressure defined as the pressure necessary to prevent osmosis from occurring.

The loop of Henle (or nephr), in anatomy, is the segment of the nephron that comes just after the proximal convoluted tubule, being a U-shaped tubular structure, with a thick and a thin portion. That can be done with the osmotic potential.

how does the cell make proteins inside the ribosome?​

Answers

Answer:When the cell needs to make a protein, mRNA is created in the nucleus. The mRNA is then sent out of the nucleus and to the ribosomes. When it is time to make the protein, the two subunits come together and combine with the mRNA. The subunits lock onto the mRNA and start the protein synthesis.

At a ribosome, an intercellular structure made of both RNA and protein, the process of making proteins occurs in a cell. The messenger RNA sequence is read by the ribosome, which then converts the genetic code into a specific string of amino acids that develop into extended chains and fold to create proteins.

What are proteins?

Proteins are defined as a macro- and large-scale biomolecules that contain one or more long chains of residues from the amino acid.

It is also defined as the results of the process of decoding, which begins with information in cellular DNA.

A protein is a biomolecule made up of peptide bonds that connect the amino acid residues in it.

There are seven types of proteins.

AntibioticsContractile proteinsEnzyme Hormonal proteinsStructural proteinsStorage proteinsTransport proteins

Thus, the process of making proteins in a cell takes place at an intercellular structure called a ribosome, which is formed of both RNA and protein. The messenger RNA sequence is read by the ribosome, which then converts the genetic code into a specific string of amino acids that develop into extended chains and fold to create proteins.

Albinism is a recessive trait where an individual does not produce the pigment melanin. A man and woman both produce melanin, but both have one parent with albinism. What is the probability that their first child will have albinism

Answers

Answer:

The child has a 1/4 chance of having albinism

Explanation:

I hope this helps!

For most types of OCA, both parents must carry an albinism gene to have a child with albinism. Parents may have normal pigmentation but still, carry the gene. When both parents carry the gene, and neither parent has albinism, there is a 25% chance at each pregnancy that the baby will be born with albinism.

What is the probability that their first child will have albinism?

This means a child has to get 2 copies of the gene that causes albinism (1 from each parent) to have the condition. If both parents carry the gene, there's a 1 in 4 chance that their child will have albinism and a 1 in 2 chance that their child will be a carrier.

Do both parents have to carry the albinism gene?

Yes, albinism is passed down (inherited) through families. People are born with albinism when they inherit an albinism gene from their parents. In albinism, both parents must carry an albinism gene for their child to be born with albinism.

The basic pattern of blood flow from the lungs to the rest of the body is: pulmonary vein; left atrium; left ventricle; aorta. The option (B) is correct.

What are pulmonary vessels?

Pulmonary veins are blood vessels that carry oxygen-rich blood from your lungs to your heart. Your pulmonary veins are part of your body's pulmonary circuit. This is a system of blood vessels that moves blood between your heart and your lungs. This circuit also includes your pulmonary arteries.

For the exchange of gases to occur effectively, the lungs require a dual vascular supply known as pulmonary and systemic circulations. The pulmonary circulation is responsible for bringing deoxygenated blood from the body to the lungs for gaseous exchange and then returning oxygenated blood to the heart.

There are 4 total pulmonary veins—with 2 pulmonary veins coming from each lung, left and right—that empty into the left atrium of the heart.

in humans, how does the circulatory system bring oxygen to every cell in the body?

Answers

Answer:

I found this in a science text, hope it helps.

Explanation:

"Blood from the heart is pumped throughout the body using blood vessels. Arteries carry blood away from the heart and into capillaries, providing oxygen (and other nutrients) to tissue and cells. Once oxygen is removed, the blood travels back to the lungs, where it is reoxygenated and returned by veins to the heart."

Basically, blood from the heart is taken away by arteries and then into capillaries, transferring oxygen to cells.

The circulatory system of human body brings about oxygen to the every cell by the help of blood. The heart of human body helps to pump up the blood with oxygen and makes it oxygenated.

What is the size of a human heart ?

A size of a human heart is a size of a human fist it has 4 chambers where with 2 auricles and 2 ventricles. The auricles receive the oxygenated blood and the ventricles get the deoxygenated blood.  

The human heart is bringing oxygen to the cells of the body where the oxygen combined with the Fe component that is iron of the blood and reaches every cell of the blood through the blood. Blood is transported to every cell of the body through the blood vessels.

Arteries carry the oxygenated blood and ventricles carry the deoxygenated blood where the blood that reaches the cellular level by the veins and the arteries along with the blood vessels that form a network.
