I’m mostly using my intuition here, but based on prior knowledge, (iii) would go with B.
This is because it is commonly known that neurons have long stoma (cell bodies) that help them connect with other neurons, as well as bushy ends, called dendrites, that connects the neurons with others. You can see that clearly in B.
Secondly, ii fits with A. Skin cells are lost constantly, as is well known, and the skin itself is comprised of a multitude of layers of skin cells. This means that skin cells are thin. In the picture A, there are thin structures that seem to be flaking off of a surface.
Thirdly, iv goes with D. The inner walls of intestines are lined with long, thin and microscopic structures called villi, which have the function of increasing surface area for absorption of nutrients. The picture shows, indeed, long, thin structures protruding from somewhere, which is an intestine.
Therefore, through process of elimination, i matches with C. I’m not that well versed with cells from the immune system. I’m guessing they’re white blood cells? I’m not sure.
These valves (more generally called the atrioventricular valves) are there to prevent back flow of blood from the ventricles to the atria when the ventricles contract. The same thing happens in both of them:
As the ventricles contract, the pressure in the ventricles increases. This, due to the fact that the valves are one way valves, causes the tricuspid and mitral valves to clamp shut. Then, as the ventricles keep on contracting, and blood is pushed upwards, is it prevented from travelling back into the atria and must travel out of the semilunar valves, through to the aorta and pulmonary artery and out of the hear.
Answer:
The Sun causes tides just like the Moon does, although they are somewhat smaller. When the earth, Moon, and Sun line up—which happens at times of full Moon or new Moon—the lunar and solar tides reinforce each other, leading to more extreme tides, called spring tides.
Answer:
A) both a particle and a wave
Explanation:
I just had this question on USA Test Prep so I know it is right.
Answer: Plant cells have a cell wall, a large central vacuole, and plastids such as chloroplasts. The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection. Plant cells have a cell wall, a large central vacuole, and plastids such as chloroplasts. The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection. The central vacuole maintains turgor pressure against the cell wall. Nucleus - DNA Storage, Mitochondrion- Energy production, Smooth Endoplasmic Reticulum (SER)- Lipid production; Detoxification, Rough Endoplasmic Reticulum (RER)- Protein production; in particular for export out of the cell, Golgi apparatus- Protein modification and export, Peroxisome- Lipid Destruction; contains oxidative enzymes, Lysosome- Protein destruction. brainliest?
