The answer is; D
The plasticity of rock in the mantle and the convection currents in the region are responsible for tectonic plate movements. The hot molten rock from deep in the mantle rise and is replaced by the cooler rock at the upper mantle. These convections are similar to those of water in a boiling pot. As the tectonic plates move (as they are dragged by these convections) and collide, earthquakes are caused. In addition, at subductions zones (where two plates collide) there occurs high volcanic activity.
<h2>Vasa recta </h2>
Explanation:
The vasa recta is a specialized capillary that branches from the efferent arteriole; The blood flow in the vasa recta runs parallel, but in the opposite direction to the flow of tubular filtrate within the nephron loop
- The vasa recta capillaries are long, hairpin-shaped blood vessels that run parallel to the loops of Henle
- The hairpin turns slow the rate of blood flow, which helps maintain the osmotic gradient required for water reabsorption
- Absorbed water is returned to the circulatory system via the vasa recta, which surrounds the tips of the loops of Henle
- Because the blood flow through these capillaries is very slow, any solutes that are reabsorbed into the bloodstream have time to diffuse back into the interstitial fluid, which maintains the solute concentration gradient in the medulla; this passive process is known as counter-current exchange
Answer:
cartilaginous joints
Explanation:
The joint system is formed by the joints, which can be defined as the joining region between two or more bones. All bones in the body except the hyoid bone are articulated with at least one other bone. There are several types of joints, among them, the cartilage joints, those that have cartilage between the bones. If this cartilage is hyaline, the joint is called synchondroses; if the cartilage is fibrous, the joint is called symphyses.
The joints are responsible for holding the bones together and allowing the skeleton to move.
Answer:
There are four main stages in the water cycle. Evaporation water can go to the clouds from about anywhere that has water ,
condensation the vapor in the cloud turns back to a liquid ,
Precipitation rain ,
and collection water that falls from the clouds as rain, snow, hail or sleet, collects in the oceans, rivers, lakes, streams. Most will infiltrate (soak into) the ground and will collect as underground water.
If a step was removed from the cycle then it there would be no water coming down. Let’s say if Precipitation was removed then what would happen. The water would be stuck up into the clouds .
The ice would be melting like it is right know and the polar bear would be going extinct because like off of a show polar bears can’t swim far and for let’s say that someplace would change like the desert would not be so hot.
A weather front is a transition zone between two different air masses at the Earth's surface. Each air mass has unique temperature and humidity characteristics. I think.
The four main phases of mitosis are:
Prophase- In the first half:The chromosomes start to shrink. The cytoskeleton begins to form the mitotic spindle, which will grow between the centrosomes and organize the chromosomes.The nucleolus goes away.
In the second half: The chromosomes become extremely compact. The nuclear envelope disappears and all the DNA comes out. Some of the mitotic spindle starts to catch chromosomes.
Metaphase- The mitotic spindle moves all of the chromosomes across the middle of the cell.
Anaphase- The two chromatids of each chromosome are pulled apart from each other and become their own chromosomes. Loose microtubules push the ends of the cell to make it longer.
Telophase- The mitotic spindle is broken back down into microtubules. Two new nuclei appear (one for each new cell). The chromosomes return to their normal form (not all squished down).
Another big step is cytokinesis, which starts either during Anaphase, or Telophase. In animal cells, the cell is pinched around the middle to create the two new cells. In plant cells, a cell plate comes into the middle of the cell and separates it into the two new cells.
The main four steps can be remembered using the acronym PMAT.
