Answer:
They can pass through the semi permeable membrane
Explanation:
The permeability of a particular solute depends on the size, solubility, properties etc and even the properties of the membrane it is aiming to pass through
If molecules are small enough, then they can pass through the semi-permeable membrane. This is as a result of permeability being inversely proportional to the molecule size.
Answer:
Z - high niche diversity and warm water temperatures
Explanation:
because high niche and warm water temperatures support more plant life, and its easier for the animals to survive these temperatures. I hope this makes sense!
The second and the third option are completely the same.
So either of them would be correct - Pelecinus polyturator.
The given question incomplete. However, the missing part is given below:
1.Which of the following are substrates of the ribonucleotide reductase reaction? 2.Which of the following are products of the ribonucleotide reductase reaction? 3.What is the best description of the reaction? 4. what is the ultimate electron donor? 5.Which of the following can directly donate an electron to ribonucleotide reductase?
Answer:
The correct answer is-
1. NDP (ADP, CDP, GDP, or TDP)
2. dNDP ( dADP. dCDP, dGDP, or dTDP)
3. Oxidation-reduction
4. NADPH
5. Thioredoxin
Explanation:
Ribonucleotide reductase reaction is catalyzed by the enzyme called ribonucleotide reductase which is a key enzyme that synthesizeS the deoxyribonucleotide from ribonucleotide, Deoxyribonucleotide is the precursor of DNA.
This reaction is an oxidation-reduction reaction that reduces all ribonucleotides ADP, CDP, GDP, or TDP to dADP. dCDP, dGDP, or dTDP. The ultimate electron donor in this oxidative-reductive reaction is NADPH however thioredoxin directly transfers an electron to ribonucleotide.
