The collision between an oceanic and a continental plate, or two oceanic plates originate volcanoes.  a) oceanic crust at convergent boundary b) heats up.

Collision area between two plates. Two continental plates might collide, or two oceanic plates, or one oceanic plate with a continental one.

In the last two cases, the thicker and older plate subduces under the other plate, and magma rises to the surface by crevices.  The Himalayas and Los Andes are examples of these collisions.

Plates' movement might produce earthquakes. Also, collisions create volcanic arches and continental arches.

When one of the plates sinks under the other one, it reaches a depth where it melts and magma rises. Volcanoes get formed on the superior plate since magma flows over it.

The subduction of oceanic crust at convergent boundary often forms volcanoes. This phenomenon occurs because the underground pressure squeezes water out of the dense crust, and this water works its way into the mantle. The water heats up the mantle and allows for the creation of magma.

Answer:T-cells are a type of white blood cell that work with macrophages. Unlike macrophages that can attack any invading cell or virus, each T-cell can fight only one type of virus. You might think this means macrophages are stronger than T-cells, but they aren’t. Instead, T-cells are like a special forces unit that fights only one kind of virus that might be attacking your body.The T-cell receptor fits with its antigen like a complex key. When the perfectly shaped virus antigen on an infected cell fits into the Killer T-cell receptor, the T-cell releases perforin and cytotoxins. ... Cytotoxins go directly inside the cell through this pore, destroying it and any viruses inside.

They have homologous structures because they have a common ancestor.

homologous structures because they have a common ancestor is the most likely reason that horses and mountain goats have hooves.

Homologous structures shoe the same structure, but may have a distinct  function, it indicate a common ancestor.

A homologous structure is an organ or bone seen  common between different animals that demonstrates an anatomical commonality indicating that the animals share a common ancestor.

on the other hand analogous structures where two unrelated species have structures with similar forms or functions due to convergent evolution.

for example of a homologous structure is the wing of a bird and an insect.

Answer:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

Answer: How does oxygen get into the bloodstream? Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.OK Our typical red cell passes from the capillary into the venules, and then into veins. It flows back to the right side of the heart, completing the second loop of its circuit [music out]. As we saw, it then travels back to the lungs.The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.

Answer:

the effects of sunlight on the aquatic life inhabiting the Amazon River. The center of all aquatic life in the Amazon is located in The Amazon Basin, the sun makes sure that all fish and plant life can sustain life.

The sunlight affects the aquatic species that lives in the Amazon River. The Amazon Basin is the epicenter of all aquatic life in the Amazon, where the sun ensures that all fish and plant life may survive.

The region of South America that the Amazon River and its tributaries drain is known as the Amazon basin. Approximately 6,300,000 km2, or 35.5 percent of South America, is covered by the Amazon river basin.

The Amazon basin not only contains the world's largest remaining tropical rainforest, it also harbours at least 10% of the known biodiversity, including endemic and threatened species of plants and animals, and its river contributes 15–16% of all river flow into the oceans.

The aquatic animals that inhabit the Amazon River are impacted by sunlight. All aquatic life in the Amazon is concentrated in the Amazon Basin, where the sun ensures the survival of all fish and plant life.

Thus, this is the chief effect of sunlight on the aquatic life inhabiting amazon river.

Answer:

Fitness or aptitude

Explanation:

Aptitude (or fitness) is the genotype/phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring.

Aptitude puts together everything that matters in natural selection. Includes the survival capability, finding a mate partner possibility, producing fertile descendants, and leaving the genes to the next generation. The aptitude of a genotype must be significant for natural selection to act in its favor.
