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).

The activities in the cell cycle occur during specific phases,in which phase of the cell cycle DNA replicated
Answer:
The cell cycle has two major phases: interphase and the mitotic phase (Figure 1). During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides.Describe how removing the carnivore will effect the population of producers
Answer:
If there were no carnivores, the herbivore populations would explode and they will rapidly consume large amounts of plants and fungi, growing until there is not enough food to sustain them. Eventually, the herbivores would starve, leaving only those plants that were distasteful or poisonous to them.

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)

Think about a pond ecosystem. List 3 examples of relationships between abiotic and biotic factors in ecosystem
Answer:
Abiotic factors refer to non-living physical and chemical elements in the ecosystem. ... Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction.
Answer: 3 examples of relationships between abiotic and biotic factors in the ecosystem are plants use sunlight, water, and carbon dioxide to make food. Another example is the interaction between turtles and soil, some turtles are known to bury themselves in the soil. Elephants and water interact as well in order to stay hydrated elephants drink water.

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.
