Answer:

mRNA: Carry genetic information from DNA to protein; serve as template for protein synthesis.

tRNA: Serves as adapter molecule and deliver specific amino acid from the cell pool to the mRNA-ribosome complex.

rRNA: Structural component of ribosomes.

Explanation:

There are three types of nongenetic RNAs: mRNA, tRNA, and rRNA.

1. The messenger RNA (mRNA) is formed by the process of transcription in the nucleus. Transcription uses template strand of DNA to specify the nucleotide sequence in mRNA. The mRNA enters cytoplasm to join ribosomes. The nucleotide sequence of mRNA serves as a template and specifies the amino acid sequence of proteins.

2. The transfer RNA (tRNA) serves as an adapter molecule during the process of protein synthesis and binds to the specific amino acids to deliver them to the protein-synthesizing machinery. The anticodon of tRNA binds to the complementary mRNA codons.

3. The ribosomal RNA (rRNA) serves as structural components for ribosomes. Each of the subunits of ribosomes is made up of rRNA and proteins.

What virus structure is similar in function to a cell membrane?

Korolek [52]

Answer:

viral envelope

The phospholipids in the viral envelope are similar to those in the plasma membrane of an infected host cell. The viral envelope is, in fact, derived by budding from that membrane, but contains mainly viral glycoproteins.

Matthew has discovered a new species of fish. During the summer months, the male fish separate themselves from the female fish a

IgorC [24]

D should be the answer as they are no longer able to perform sexual reproduction without the other fish. Therefore, they would die off because they have lost the partner needed to reproduce.

Hope this helps!

First, there is a need to understand what the carrying capacity is as it relates to the environment:

Carrying capacity refers to the maximum number of individuals of a particular species that and environment can support based on the resources it has.
The population of a species in an environment grows and oscillates around the carrying capacity of the environment.

Now let us look at the graph. The population size grew from 0 and then leveled off at 2,000 with time. The leveling-off also happened without any oscillation, meaning that the maximum population size the environment can support is 2,000.

Hence, the portion on the graph that indicates the carrying capacity would be the plot where the population size is 2,000 and the time being between 12 and 18. This has been circled and labeled as 'K' in the attached image.

Igestion of carbohydrates within the small intestine involves enzymes that come from the? a: mouth. b: stomach. c: pancreas. d:

ella [17]

Enzymes come from the pancreas.

What are Enzymes?

Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.

The small intestine, not the stomach, is where carbohydrates are chemically broken down. The chemical breakdown of digestible carbohydrates is completed by disaccharidases and pancreatic amylase. The circulation carries the monosaccharides to the liver after absorption.
