In response to high amounts of phosphate transport into the cell: a. PhoR is phosphorylated by the phosphate transporter protein

storchak [24]

Answer:

e. PhoU keeps PhoR bound to the phosphate transporter protein Pst

Explanation:

PhoU is a membrane protein known to regulate the transport of phosphate (Pi) between cellular compartments. It has been discovered that mutations in this protein cause lethality because the cell becomes incapable of controlling the intracellular levels of Pi, this being toxic for the cell. PhoR is a histidine kinase/phosphatase. When the Pi level is considered to be a limiting factor, PhoR autophosphorylates at a histidine residue and then donates its phosphoryl group to PhoB. On the other hand, when the Pi level is high, this protein removes the phosphoryl group from phospho-PhoB. Finally, the Pst is a signal transduction protein that acts as a transporter capable of switching its conformation during the transport of PI.

Which list gives the proper sequence of energy changes that occur in a hydroelectric plant?

ASHA 777 [7]

D

Explanation:

Flowing water has intrinsic kinetic energy that is harnessed to rotate the turbine. The turbine rotates hence gains mechanical energy because it is doing work. This work is used to rotate a dynamo of a generator which generates electricity. The mechanical energy is thus converted into electric energy by the dynamo. The electric energy is then carried by the power lines to the users.

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.

What hypotheses were supported through not only David Blehert’s initial experiment, but also by the follow-up experiments both h

BlackZzzverrR [31]

Answer:

<em>The fungus can be transmitted through contact and the fungus is deadly to bats.</em>

Explanation:

David Blehert was a scientist who had received a PhD in the field of bacteriology.

David Blehert's hypothesis provided evidence that white-nose fungi were capable of causing death in bats. Even exposure of healthy bats to the bats which were infected with white-nose fungi caused illness and even death of the previously healthy bats.

David Blehert's hypothesis was also supported by other people who conducted the experiments and hence, was considered to be true.
