Answer:
d. nicotinamide adenine dinucleotide (NAD) and derivatives.
Explanation:
a. amino acids (such as cysteine and proline)
b. vitamins (such as riboflavin and thiamine)
c. Adenosine triphosphate
d. nicotinamide adenine dinucleotide (NAD) and derivatives.
<em>Growth factors of bacteria are compounds that are important for the growth of bacteria but which cannot be synthesized by the bacteria themselves. Without these compounds, the growth of bacteria would be limited or they will not even grow at all.</em>
These compounds which are usually organic in nature include purine and pyrimidine nucleotides, vitamins, amino acids, and hormone-like peptides.
From the options, only option d does not fall among the growth factors required by bacteria.
Hence, the correct option is d.
Answer:
cohesion
Explanation:
One of water's most distinctive properties is cohesion—that is, the tendency of water molecules to "stick" to one another. In plants, this cohesion results in columns of water that stretch through the plant's xylem, from the roots all the way to the leaves.
Hope this helps:)
<u><em>NAD+ and H+ are not the same. </em></u>
NAD+ is an electron carrier. Reactions in metabolism oxidize food molecules and transfer those electrons (along with H+) to > NAD+ which is what forms NADH. Now, NADH is the reduced form of NAD+ and NAD+ is the oxidized form of NADH.
H+ on the other hand, is a proton. It is a hydrogen atom that lost it's electrons. So when you see NADH + H+, that means that the reaction removed 2 electrons and 2 H+ from the compound.
The leading is replicated continuously for the entire length of the chromosome, while the lagging strand is replicated in pieces.
Answer:
A) repressors
Explanation:
A transcription factor is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to specific DNA sequence. The function of TFs is to regulate-turn on and off genes-In order to make sure that they are expressed in the right cell, at the right time and in the right amount throughout the life of the cell and the organism. Groups of TFs function in a coordinated fashion to direct cell division, cell growth and cell death throughout life.
