Answer:

Microscopic charcoal, Vegetation.

Explanation:

As the researchers conducting research in the Nile region identified that an increase in temperatures leads to an increase in droughts and reduction of natural vegetation and thereby the chances of the occurrence of natural fires.

The Channel Islands are a series of small islands off the California coast. Each island has a genetically distinct population of foxes. Compare the population of foxes on one of these islands to the population of foxes in the forests of mainland California. Which is more likely to be impacted by genetic drift? Which is more likely to be at Hardy-Weinberg equilibrium?

Answers

Answer:

The fox population on the Islands experiences genetic drift  whereas foxes in the forests has Hardy-Weinberg equilibrium.

Explanation:

The fox population on the Islands experiences genetic drift because there is no chance of introduction of different type of foxes in these Islands which experiences less variation in the population of already existing foxes. Genetic drift is the change that occur in the frequency of an existing gene allele in a population due to random sampling of organisms. Genetic drift may cause gene variants to disappear completely with the passage of time which leads to reduce genetic variation. The foxes that is located in the mainland forest experiences Hardy-Weinberg equilibrium.

) An allosteric interaction between a ligand and a protein is one in which: (3 pts) A) binding of a molecule to a binding site affects binding of additional molecules to the same site. B) binding of a molecule to a binding site affects binding properties of another site on the protein. C) binding of the ligand to the protein is covalent. D) multiple molecules of the same ligand can bind to the same binding site. E) two different ligands can bind to the same binding site.

Answers

Answer:

B) binding of a molecule to a binding site affects the binding properties of another site on the protein.

Explanation:

In an allosteric interaction between a protein and a ligand, the ligand binds to a site in the protein. As a result, there is a change in the properties of other active sites on the protein. These active-site changes may or may not allow the protein to bind to other molecules. There is a change in the protein that affects the affinity of the active site for other molecules. The affinity on the active site increases if the protein binds to an activator and decreases if the protein binds to an inhibitor molecule.

A mutation occurred in the following DNA sequence AGCCTAGCC and the mutated form is now AGCCTTAGCC. Which of the following correctly describes the result of this mutation?

1.A deletion occurred so all of the amino acids added after the mutation may be wrong.

2.An insertion occurred so all of the amino acids added after the mutation may be wrong.

3.A substitution occurred so all of the amino acids added after the mutation will definitely be wrong.

4.An insertion occurred so all of the amino acids added after the mutation definitely will be different.

Answers

Answer:

Explanation:

1.A deletion mutation occurs when a wrinkle forms on the DNA template strand and subsequently causes a nucleotide to be omitted from the replicated strand.

2.This type of variant results in a shortened protein that may function improperly, be nonfunctional, or get broken down. An insertion changes the DNA sequence by adding one or more nucleotides to the gene.

3. A substitution mutation can cause the following: Change in the coding of amino acids codon to a particular stop codon resulting in an incomplete protein, which is usually non-functional. Can cause Silent mutations where a codon change can encode the same amino acid resulting in no changes in the protein synthesized.

4. when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.

define and describe osmosis​

Answers

Answer:

Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.

Explanation:

Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.

Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.

Mark Brainliest please

Poikilothermic animals include types of vertebrate animals, specifically some fish, amphibians, and reptiles, as well as many invertebrate animals.

Reptiles are cold-blooded, or ectothermic, animals. This means that they cannot produce heat in their own bodies, and have to rely on their surroundings to keep warm. This is why most reptiles are found in hot or warm climates. Reptiles often bask in the sun to get warm.

Both reptiles and amphibians are poikilothermic, which means that they cannot regulate their own body temperatures internally as birds and mammals do.

PLSSS HELLLPP- Which of the following measurements uses a derived unit? O volume O mass O length O time​

Answers

Answer:

Volume

Explanation:

volume=length ×length ×length

The metric system is the system used for the measurement. It measures the mass, length, weight, time, etc. The unit of volume is a derived unit. Thus, option A is correct.

What is a derived unit?

A derived unit is a unit used to measure and estimate the substance by using the basic or the fundamental metric unit system. It is based on units of the fundamental system.

The fundamental units include mass, temperature, time, luminous intensity, length,  electric current, and amount of substance. On the other hand, derived units result from a combination of base units.

A volume is a derived unit as it came from the fundamental unit of length as,

Volume = length × length × length

= cm × cm × cm

= cm³

Therefore, option A. volume is a derived unit.
