When oceanic and continental plates converge, the oceanic plate tends to go under the continental plate and eventually melts. Which feature below forms at these types of boundaries?
A) rift valley
B) seafloor spread
C) volcanic mountains
D) folded mountains
Answers
When oceanic and continental plates converge, the oceanic plate tends to go under the continental plate and eventually melts. Volcanic mountains forms at these types of boundaries. Thus, option C is correct.
How are mountains formed?Mountains are often formed by the movement of tectonic plates on the earth's crust. The crust itself is made by the different large tectonic plates. There are three ways to form a mountain which is following, volcanic, fold, and block mountains.
The great African rift valley and Rhine valley in Germany is an examples of block mountains. Fold mountains are the Himalayas, Alps, and the Rockies. Volcanic mountains are Vesuvius, Kilimanjaro, and Mount Fuji.
"At a divergent boundary in a continental plate" is the one among the following choices given in the question that tells where a rift valley is most likely to occur.
Therefore, When oceanic and continental plates converge, the oceanic plate tends to go under the continental plate and eventually melts. Volcanic mountains forms at these types of boundaries. Thus, option C is correct.

Answers
Answer:
Despite differences in structure and function, all living cells in multicellular organisms have a surrounding cell membrane. Just as the outer layer of your skin separates your body from its environment, the cell membrane (also known as the plasma membrane) separates the inner contents of a cell from its exterior environment. This cell membrane provides a protective barrier around the cell and regulates which materials can pass in or out.
Structure and Composition of the Cell Membrane
The cell membrane is an extremely pliable structure composed primarily of two layers of phospholipids (a “bilayer”). Cholesterol and various proteins are also embedded within the membrane giving the membrane a variety of functions described below.
A single phospholipid molecule has a phosphate group on one end, called the “head,” and two side-by-side chains of fatty acids that make up the lipid “tails” (Figure 3.1.1). The lipid tails of one layer face the lipid tails of the other layer, meeting at the interface of the two layers. The phospholipid heads face outward, one layer exposed to the interior of the cell and one layer exposed to the exterior (Figure 3.1.1).
This diagram shows the structure of a phospholipid. The hydrophilic head group is shown as a pink sphere and the two tails are shown as yellow rectangles. This diagram shows a phospholipid bilayer. Two sets of phospholipids are arranged such that the hydrophobic tails are facing each other and the hydrophilic heads are facing the extracellular environment.
Figure 3.1.1 – Phospholipid Structure and Bilayer: A phospholipid molecule consists of a polar phosphate “head,” which is hydrophilic and a non-polar lipid “tail,” which is hydrophobic. Unsaturated fatty acids result in kinks in the hydrophobic tails. The phospholipid bilayer consists of two adjacent sheets of phospholipids, arranged tail to tail. The hydrophobic tails associate with one another, forming the interior of the membrane. The polar heads contact the fluid inside and outside of the cell.
The phosphate group is negatively charged, making the head polar and hydrophilic—or “water loving.” A hydrophilic molecule (or region of a molecule) is one that is attracted to water. The phosphate heads are thus attracted to the water molecules of both the extracellular and intracellular environments. The lipid tails, on the other hand, are uncharged, or nonpolar, and are hydrophobic—or “water fearing.” A hydrophobic molecule (or region of a molecule) repels and is repelled by water. Phospholipids are thus amphipathic molecules. An amphipathic molecule is one that contains both a hydrophilic and a hydrophobic region. In fact, soap works to remove oil and grease stains because it has amphipathic properties. The hydrophilic portion can dissolve in the wash water while the hydrophobic portion can trap grease in stains that then can be washed away. A similar process occurs in your digestive system when bile salts (made from cholesterol, phospholipids and salt) help to break up ingested lipids.

Which are more closely related, the Giant Panda and the Red Panda or the Giant Panda and the Polar Bear?
Justify your answer.
Answers
Answer:
The giant panda and polar bear
Explanation:
I think this because they are both bigger species of bear where as the red panda is smaller. the red panda has more of a raccoon body shape where a panda has a similar body type as a panda.
The Giant Panda is closely related to bears, especially polar bears, while the red panda is more closely related to ferrets.
What is Giant Panda?A giant Panda may be defined as a bearlike mammal inhabiting bamboo forests in the mountains of central China. They are also known as Panda Bear.
Even sharing a common name, the Giant pandas and the red panda are not closely related. Red pandas are members of the taxonomic family Ailuridae, while giant pandas are members of the bear family Ursidae.
Therefore, The Giant Panda is closely related to bears, especially polar bears, while the red panda is more closely related to ferrets.

WHICH SPECIES OF ANIMALS ARE AFECTED THE MOST BY ACTIONS OF HUMANS IN CURRENT TIMES?SUGGEST WAYS TO PROTECT THEM.
Answers
Answer:
Polar Bears
Explanation:
The species that has most likely been the most affected by human actions would be the Polar Bears. The human population is growing at a staggering rate and this causes industrialization to expand rapidly as well. This continued and increasing use of fossil fuels for all of our basic necessities is rapidly heating up our world (Global Warming) and melting the ice caps. Without this it becomes nearly impossible for Polar bears to survive as they cannot find shelter and ultimately end up starving to death due to not being able to hunt for food as well. The only way to protect them is to begin protecting our planet, switching to more environmentally friendly sources of energy, and being mindful of our choices.

Answers
Answer:
Natural selection.
Explanation:
Natural selection is when organisms who are most adapted to their environment survive and pass on their genes while those with "unfit" genes die and don't get the chance to reproduce! This slowly creates a population that is most well suited to their habitat. Hope this helps again LOL! :)

In addition to their position in doing away with waste from the frame, the kidneys additionally balance fluids within the frame, launch hormones to regulate blood stress, and manage the manufacturing of purple blood cells.
The ureter is a small tube, or duct, that connects the bladder and kidneys. Urine passes thru the ureter from the kidneys to the bladder. The urethra is the tubular path that connects the bladder to the body's outside, permitting urine to go out the frame.
Urine drains from the renal pelvis of each kidney into the ureters. The ureters are long, thin tubes made of smooth muscle. Contractions of the smooth muscle push urine down through the ureters and into the bladder.
