Why are zebra mussels able to spread so quickly in the United States?

Why do you think adult male crabs have such a large claw? What could be the purpose of it? And can you think of any other animal

Romashka [77]

Answer:

cause they use the small one for feeding and the large one to attract a female crab for mating, the large claws are also used as a weapon

Which mechanism do the different organism populations found across the tundra exemplify?

Grace [21]

In the Tundra region, the diversity of the organisms present is high. Multiple different species of different organisms are present in these regions, which makes them a diverse area on the Earth. The mechanism responsible for these different populations is the species diversity.

It can be defined as the total number of species that are present in a given community.

During metabolism the complete of one molecule of glucose results in a maximum yield if 38 molecules of

Bond [772]

During cellular respiration, which is a part of metabolism, one molecule of glucose produces a maximum yield of 38 molecules of ATP (adenosine triphosphate). ATP is the energy form that cells use to function and has also been often called the "currency" of the cells.

The whole process begins with breakdown of food by the digestive system right down to their monomer units. Carbohydrates are broken down into glucose, which is carried by blood to all cells of the body.

Each cell takes in glucose and breaks it down through the respiration process that begins with glycolysis in the cytoplasm which yields 2 ATP molecules, then onward into the mitochondria of the cell where Krebs cycle and electron transport chain processes generate 34 to 36 more molecules of ATP.

In order to make a protein the messenge on DNA must be converted to what?

Soloha48 [4]

Explanation:

-mRNA or messenger RNA

DNA wound into chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand.

Further Explanation:

Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.

Basic makeup: C, H, O, P; they contain phosphate group 5 carbon sugar, these nitrogen bases which may contain single to double bond ring.

Nucleic acids like DNA stores all of an organism’s genetic information. Nucleic acid molecules comprise the nitrogenous bases Guanine, Adenine, Cytosine and Thymine. Conversely, RNA nucleotides are Adenine, Guanine, Cysteine and Uracil. These pair up as base pairs due to their varied structure- largely influenced by the location of N molecule.

In certain combinations, these bases form codons which act as instructions for protein synthesis. Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis.

RNA codons determine certain amino acids, so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Guanine, Cysteine and Uracil). Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.

Thus, these contribute to the broad diversity of living organisms, as varied combinations of these 64 codons can produce many proteins which can be organized into cells, tissues and organisms.
