Answer:
Two possible negative implications that free higher education could have on prospective students would be the following:
-A greater student competition, where by virtue of the right to equal and unrestricted access to education, these prospective students would see their possibilities for academic development liquefied, by competing with an unlimited number of peers both in access to vacancies and in the internal possibilities of University.
-On the other hand, free education, by guaranteeing unrestricted access without academic limits, would lower the level of universities, limiting the academic development of more qualified students.
The two possible negative implications that free higher education may
have for prospective students include the following:
Risk of overcrowding.Reduced quality.What is Overcrowding?Overcrowding refers to a situation in which people are many in a
particular space which poses health risks.
Free higher education may pose such risks as a result of the education
being free. There would also be reduced quality because the teacher and
students won't be able to pay adequate attention to one other.

Why is it important that all amino acids share a common structure and only vary in their side group?
Answer:
The side groups are what make each amino acid different from the others. Of the 20 side groups used to make proteins, there are two main groups: polar and non-polar. ... The polar and nonpolar chemical traits allow amino acids to point towards water (hydrophilic) or away from water (hydrophobic).

D. When the guard cells inflate with oxygen, they become stiff and
the pore opens.
A. When the guard cells are full of water, they become stiff and hold
the pore open.
Two guard cells make up the stomata. The walls of these cells are thicker on the inside than they are on the outside. Stomata open when they take in water and close when they lose water due to the unequal thickness of the paired guard cells.When stomata open, they release water vapor and other gases into the atmosphere, including oxygen.A.

Volcanos extend so deep below earth’s surface that they reach down to the next layer. Which is the second layer of earth?
Answer:
mantle
Explanation:
The mantle is very thick: 1800 miles deep. The mantle is a little bit like a sandwich. On the top and bottom parts of the mantle, the rock doesn’t move very much. In the middle of the mantle is the asthenosphere. This part of the mantle moves around fairly slowly. This moving mantle layer pushes the earth’s plates around.

How are unknown minerals identified?
Answer:
Minerals can be identified by their physical characteristics. The physical properties of minerals are related to their chemical composition and bonding. Some characteristics, such as a mineral's hardness, are more useful for mineral identification.
Explanation:
Answer:
1. Hardness, the ability to resist being scratched—or hardness—is one of the most useful properties for identifying minerals. (ex. diamond)
2. Luster, luster is how a mineral reflects light.
3. Color, one of the most obvious properties of a mineral is color. (ex. Red- Ruby, Green- Jade, Blue- Opal)
4. Streak, the color of a mineral in its powdered form. It is usually obtained by rubbing the mineral on a hard, white surface, such as a tile of un-glazed porcelain, so as to yield a line, or streak, of fine powder. (Kinda like rubbing chalk on a concrete floor to get the color)

Explain the role of living things such as yourself in the nitrogen cycle
Simple answer please
Answer:
Role of organisms in the nitrogen cycle:
Bacteria play a central role: Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates. Bacteria of decay, which convert decaying nitrogen waste to ammonia. Nitrifying bacteria, which convert ammonia to nitrates/nitrites.
Explanation:
I THINK THIS IS SHORT AND EASY
Plants use nitrates to create proteins. Animals eat plants for protein. Humans add nitrogen-rich fertilizers and manure to the cycle.
What is nitrogen cycle?The process by which nitrogen is changed into a variety of different chemical forms as it cycles through different ecosystems, including the atmosphere, land, and ocean, is known as the nitrogen cycle, which is a biogeochemical cycle. Both biological and physical methods can be used to complete the transformation of nitrogen.
In order to synthesize proteins, plants must first take up nitrates from the surrounding soil. Plant material is digested by animals, which then contributes to the formation of animal protein. Both the addition of nitrogen-rich fertilizers to the soil and the utilization of manure are examples of how humans make a contribution to the cycle.

A semi permeable membrane is placed between two solutions the membrane is only permeable to water on the right side is a 10% salt solution on the left side is distilled water 100% water in which direction will the net movement of water occur
Most water molecular move from x to y decreasing the concentration gradient of sucrose. The solution will always move down the concentration gradient.
This means the water always move from this is more water to where there is less water.
Therefore, water will move from a hypotonic solution to the hypertonic solution.

The scenario which describes a relationship of parasitism is a tick feeds on the blood of a dog. Therefore, the correct option is D.
What is parasitism?In parasitism, one organism (the parasite) benefits at the expense of another organism (the host). In this scenario, the tick benefits by feeding on the dog's blood, while the dog is harmed by the loss of blood and potential transmission of diseases by the tick.
Option A describes a mutualistic relationship, where the ox pecker birds benefit by feeding on the ticks, and the zebras benefit from having the ticks removed.
Option B describes a predator-prey relationship, where the polar bear benefits by catching and eating the seal, while the seal is harmed by being eaten. Option C and D describe commensalism. They both are same. Therefore, the correct option is D.
