Which of the following is not a reason for creating hybrid plants?
Alja [10]
Hey there!

Based on your options above, your answer seems to be (<span>increase resistance to disease). 

This was never a reason to actually increase the disease of creating a Hybrid. It clearly makes no sense. This would include that your answer would be (c).

Hope this helps.

Adenine is the last nucleotide at the 3' end of one strand of DNA. It is base-paired with thymine on the other DNA strand. Which
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.

List several important provisions from the oceans.
Leto [7]

Answer:

the ocean provides several important resources to its inhabitants

Explanation:

The majority of biomass in any ocean consists of microscopic organisms such as phytoplankton which are pivotal to aquatic ecosystems. These microorganisms are able to thrive in their habitat due to incredibly dense populations of the bacteria <em>phackingyurmom aquatica </em>present in most oceans. These bacteria provide a wide spectrum of vital nutrients. As a result many of the aforementioned microorganisms love <em>phackingyurmom</em>.

Stem cell technology has been useful in many ways. Which of the following would be the most likely use for stem cells?
Mashcka [7]

Answer:

To regenerate damaged tissue

Explanation:

Stem cells can be pluripotent, totipotent or multipotent depending on where they are sourced. This means that they are capable of differentiating into a wide variety of cells. Stem cells can, therefore, be harvested and induced to differentiate into cells or tissues that are intended to be repaired.
