Which category includes humans and all other animals
Answer C) consumers
Explanation : consumers depends on plants or other animals to feed themselves.
Hope this helps!
Answer:
In most cells, DNA directs the production of a molecule of mRNA which then enters a ribosome. The ribosome produces the final product, a protein. Retroviruses do the opposite. They use the enzyme reverse transcriptase to use a template of mRNA to produce DNA.
Explanation:
The central dogma of molecular biology describes how a cell uses its genetic information to synthesize a protein. The first step called 'transcription' consists of using an RNA polymerase enzyme and a fragment of DNA (i.e., gene) as a template to synthesize an RNA molecule, usually a messenger RNA (mRNA). Subsequently, the genetic code in the mRNA sequence is read by the ribosomes in order to produce a protein, a process known as 'translation'. Retroviruses are viruses that have the ability to integrate into the host genome by using a reverse transcriptase enzyme that allows reverse transcription of mRNA to complementary DNA, which then integrates into the host's genome.
Answer:
glutamine synthetase-glutamate synthase
b)Glutamate dehydrogenase catalyzes the same reaction, but only under conditions of very high NH4+ levels such as agricultural fertilizers since the reaction is unfavorable under standard conditions (ΔGº’ = +30kJ/mol). Under physiological conditions, this reaction deaminates glutamate.
Explanation:
The importance of the first reaction you can see that it needs a molecule of ATP in order to create the catalysm, so that´s why that enzyme is called synthetase, since it needs a molecule of ATP to do its work, the other one, the glutamate synthetase, because it does not need the molecule of ATP to do so.
Glutamate can only catalyze the reaction under certain not found in nature regularly conditions, that´s why it doesn´t work as a dehydrogenase.
The functional unit of the kidney is nephron. Kidney comprises two kinds of nephrons, each situated in distinct sections of the renal cortex, that is, juxtamedullary nephrons and cortical nephrons. A nephron constitutes of a renal tubule, renal corpuscle, and the associated network of capillaries. The nephron is accountable for eradicating waste from the body.
The functional unit of lungs is alveoli. They resemble a cluster of grapes, they are thin and possess moist walls. They are a single layer of cells enveloped by a layer of capillaries. The main function of the lungs is respiration. The alveoli help one to breathe, by conducting the process of gas exchange.
