which they are used or produced.
Complete the passage about the process of subduction.
The subduction of
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

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

What is the most likely reason that horses and mountain goats have hooves?
They have homologous structures because they have a common ancestor.
They have analogous structures because they have a common ancestor.
These are vestigial structures in both animals because they are not used.
These are similar structures due genetic mutations.
What is the answer to this?
Answer:
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.
what is homologous structure ?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.

How do T-cells help with destroying viruses?
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.

Write a set of directions for a red blood cell to deliver oxygen to the brain. Lungs heart-brain aorta arteries veins
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.

When heat is introduced to matter, what happens to the matter at the molecular level?
Explain in science
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.

How does the position of Earth and its orbit affect climate change?
Answer:
The Earth's orbit around the Sun is an ellipse, but it does change shape. ... At other times, the ellipse is more pronounced so that the Earth moves closer and further away from the Sun as it orbits. When the Earth is closer to the Sun our climate is warmer and this cycle also affects the length of the seasons.
