Both. You can use it as singular or plural.
In the Claritin commercial, the man is laying in the grass with a
beagle puppy. The beagle is a breed of small hound that is similar to a larger
foxhound that has approximately
220 million scent receptors. This is the reason why they are employed as
detection dog and not as guard dogs for they are usually friendly dogs.
Answer:
Atmospheric nitrogen is "fixed" by bacteria.
Explanation:
Nitrogen gas (N2) is the most abundant in the earth's atmosphere, representing 79% of air volume. In organisms, nitrogen atoms are part of several organic substances, such as proteins and nucleic acids. However, most living things cannot use nitrogen in the N2 molecular form. Only a few species of bacteria are able to use it by incorporating nitrogen atoms into their organic molecules and making it available in other molecular forms for use by various species through a process called Biological Nitrogen Fixation. Similarly, the bacteria that perform the fixation are called nitrogen fixers.
Answer:
CAAGGUCUC
Explanation:
In an RNA strand, the bases would be Thymine, Uracil, Guanine and Cytosine.
The difference in the bases between DNA and RNA is that in RNA the complementary base of thymine is uracil, but in DNA the complementary base of thymine is adenine.
Substrate -level phosphorylation accounts for approximately 100% of the ATP formed by the reactions of glycolysis.
The direct transfer of a phosphate group to ADP to form ATP is known as substrate-level phosphorylation. It accounts for all of the ATP produced by glycolysis reactions. The first substrate-level phosphorylation occurs when 1,3-diphosphoglyceraldehyde is converted to 1,3 diphosphoglyceric acid and 2 NADH2, resulting in the formation of 6 ATP. Substrate-level phosphorylation converts the 1, 3-diphosphoglyceric acid to 3 phosphoglyceric acid, which produces 2 ATP. The second substrate-level phosphorylation takes place when phosphoenolpyruvic acid is converted to pyruvic acid, which results in the formation of two ATP molecules.
