Answer:
b. An increase in the population of prey it feeds on
Explanation:
There's only one way in which the predator population can be growing, and that is if the population of the prey animals is growing as well. The reason for this is that the prey animals are the ones that the predators feed upon, so the less prey animals there are, the less food, thus less predators, and the more prey animals there are, there's more food, thus more predators. It is a predator-prey relationship that directly affects both sides and their numbers. The population of predators will grow as the population of prey animals is growing, but eventually that will stop as the increased number of predators will regulate the prey population, thus reaching an equilibrium in the ecosystem.
Answer:
Protein molecules.
Explanation:
Protein, highly complex substance that is present in all living organisms. A chain of amino acid residues is called a polypeptide which is a bond form by the carboxylate ion on one end and the -Nh2 on the other end via condensation reaction.
Proteins are large biological molecules (macromolecules), which consists of one or more long chains of amino acid residues. Proteins perform certain functions in organisms like Enzymes - catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells, transporting molecules from one location to another etc.
Proteins differ from one another in their amino acid sequence, which is dictated by the nucleotide sequence of their genes, which usually results in protein folding into a three-dimensional structure that determines its activity.
The similarity they have is that they both produce two identical cells to each other and to the mother cell, but the mechanism is totally different as binary fission takes place in prokaryotic cells while mitosis takes place in eukaryotic ones.
Primary function is reproduction. High fidelity replication in which chromosome number is maintained through a checkpoint at metaphase. Errors occur, but more rarely than in fission.
Uses cytokinesis to divide cytoplasm.
Answer:
1) Density
2) False
3) True
4) mass. arranged
5) graduated
6) False
7) Less, further
8)False
9) Density
Explanation:
1) Mass of atoms, size, and arrangement directly determine density of a substance.
2) Density = m/v,
3) Submerged objects must displace liquid equal to its volume because you are adding mass into a body of water
4) same as #1
5) Graduated cylinders are the most commonly used measurement tool for measuring volume
6) If it is the same substance it is equal in density. D=m/v, even if one sample is larger, both m and v increases
7) Hotter things have faster moving molecules so they are further apart. This causes the molecules to be less compact and thus less dense.
8) Liquids only float if it is less dense then the liquid it is placed on.
9) Density determins buoyancy.
Cellulose belongs to carbohydrates.
Cellulose is classified as a carbohydrate, a polysaccharide, as they are formed of the glucose monomers chain. It is the prime component in the walls of the cells of plants, assisting the plants to remain upright and stiff. Humans cannot digest cellulose due to the absence of cellulase, however, it is essential in the diet as fiber.
However, the animals like sheep, cows, and horses can digest cellulose that is why they can acquire nutrients and energy they require from the grass.
