Explanation:
Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. ... Wegener suggested that these creatures were alive in warm climate zones and that the fossils and coal later had drifted to new locations on the continents.
helper t cells secrete ________ to stimulate the proliferation of b cells.
Answer:
Helper T cells are activated when they bind to their target antigen being displayed on an antigen-presenting cell. These cells then release what chemical? Cytokines, which is a chemical that signals B cells and other T cells to activate.
Helper T cells secrete cytokines to stimulate the proliferation of B cells.
What are Helper T- Cells?Helper T cells, also known as CD4+ T cells, are a type of white blood cell that play a critical role in the adaptive immune response. They are called "helper" cells because they help activate and coordinate other cells in the immune system, including B cells and cytotoxic T cells, to mount an effective response against a specific pathogen or foreign substance.
Helper T cells recognize and bind to antigens presented by antigen-presenting cells, such as dendritic cells, and then secrete cytokines that activate and differentiate other immune cells.
They also play a role in regulating the immune response to prevent excessive inflammation and tissue damage. Helper T cell dysfunction or depletion is associated with a number of autoimmune and infectious diseases.

The nuclear equation shows the transmutation of a form of radon into polonium and an alpha particle. In one tho two sentences, explain whether or not the reaction is balanced.
The equation is balanced because the mass and charge are equal on both sides of the reaction equation.
In a nuclear reaction, one nucleus is transformed into another. In this case of the equation shown, the radon nucleus is being transformed into a polonium nucleus with the emission of an alpha particle.
The equation is balanced because a total mass of 219 is found on both sides of the reaction equation and a total charge of 86. Recall that an alpha particle is the same as a helium nucleus with a mass of four units and a charge of two units.

in humans, how does the circulatory system bring oxygen to every cell in the body?
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.
I hope I could help!
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.

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

O pulmonary artery; left atrium; left ventricle; aorta.
O vena cava; aorta; right ventricle; right atrium.
O pulmonary vein; left atrium; left ventricle; aorta.
Answer: pulmonary vein; left atrium; left ventricle; aorta
Explanation: I just did this question in the final exam of A&P and it was correct, hope this helps:)
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.

The production of orchids by cutting is an example of vegetative propagation.
There are two methods of growing orchid trees i.e. through seed as well as from vegetative part. Most of the farmers grow orchids plants through vegetative propagation because it takes less time to reach maturity while on the other hand, growing orchids through seed takes more time.
So that's why the farmer prefers vegetative propagation as compared to seed so we can conclude that the production of orchids by cutting is an example of vegetative propagation.

which parts of the monomers involved in the dimer formation
Answer:
A dimer (/ˈdaɪmər/) (di-, "two" + -mer, "parts") is an oligomer consisting of two monomers joined by bonds that can be either strong or weak, covalent or intermolecular. The term homodimer is used when the two molecules are identical (e.g. A–A) and heterodimer when they are not (e.g. A–B).
how does the cell make proteins inside the ribosome?
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.

Why do parrots mimic people?
Answer:
Parrots are intelligent and highly social animals with long life spans, just like people. ... So a domestically-bred parrot, such as a budgerigar, that mimics its people is doing what wild parrots naturally do: they are learning and repeating sounds made by its family and flock mates, who happen to be people.
Explanation:
Parrot expert Michael Schindlinger of Lesley University explained in Scientific American in 2007 that mimicking helps parrots separate members of their own community from outsiders. It can allow a bird to find its mate and prevent intracommunity conflicts over territory.
