If there were 2,000 units of biomass among the primary producers of a food chain, how much biomass would be expected among the t
zepelin [54]

Answer:

2 unit

Explanation:

According to the 10% law, the transfer of biomass energy from one higher trophic level to lower trophic level is only 10%.

Primary(Producer)→Primary consumers→secondary consumers→tertiary consumers.

that is 2000→200→20→2

note: only 10% of the total biomass is received by the next trophic level.

therefore tertiary consumers will receive 2 units of biomass.

Jlenok [28]

Answer:

The two nucleotides are located on DNA strands that are parallel to each other

Explanation:

Deoxyribonucleic acid, commonly known as DNA, is one of the two types of nucleic acids. It is a molecule composed of a nitrogenous base, pentose sugar and a phosphate group. According to the information given in this question, Adenine is the last nucleotide at the 3' end of one strand of DNA. The following are factual about the nucleotide;

- Since DNA is a double-stranded molecule, the Adenine nucleotide will be base-paired with Thymine nucleotide (complementary base pairing) on the other DNA strand.

- Since complementary DNA strands are opposite to one another, this means that if the adenine has an unlinked 3' hydroxyl group, then the thymine must have an unlinked 5' phosphate group.

- Nucleotides in a DNA strand are joined to one another via a covalent bond called PHOSPHODIESTER BOND. Hence, the adenine and the thymine are each bonded to the previous nucleotide in the strand by a phosphodiester bond.

- In the complementary base pairing between two nucleotide bases, there are two hydrogen bonds between the adenine and thymine nitrogenous bases i.e. A=T.

- DNA strands that make up a molecule are complementary and opposite to one another, hence, they are said to be ANTIPARALLEL.

Ratling [72]

Answer:

Explanation:

The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics of the eruption.
