Answer:
d
Explanation: the genes carry what is needed to change, and the cells change due to what is happening in the genes
Answer:
Bone marrow transplantation
Explanation:
Stem cells are special cells generated in bone marrow. This can changed into different types of cells. They are red blood cells It carries oxygen to the body cells
.White blood cells Resisting agents from infections
. Platelets it performs clotting of blood
Stem cell transplant involves in removing of damaged cells instead placed stem places from blood or bone marrow
Answer:
Option C. Dicer
Explanation:
Dicer is a dsRNA endoribonuclease like bacterial Class III RNaseIII that is encoded by the DICER1 gene contains a N-terminal ATP-subordinate RNA helicase motif or domain.
Dicer cuts or cleaves precursor RNA molecules to make miRNA molecules. MicroRNAs regulates gene expression by hindering the procedure of protein creation. In the initial step of making a protein from a gene, another sort of RNA called RNA (mRNA) is made and goes about as the plan for protein production.
Answer:
Reduced reabsorption of salts and nutrients from the proximal tubule.
Explanation:
The proximal convoluted tubules are the site for reabsorption of the largest amount of solute and water from the filtered fluid. It reabsorbs 65% of water, electrolytes such as Na+ and K+, almost 100% of the filtered glucose and amino acids and other electrolytes such as Ca2+, Mg2+, etc.
The simple cuboidal epithelial cells of the proximal convoluted tubule have a prominent brush border of microvilli on their apical surface. These microvilli serve to increase the surface area for reabsorption and secretion. Destruction of these microvilli would reduce the reabsorption of the above-mentioned salts and nutrients from proximal convoluted tubules.
Out of the following given choices;
a) The amount of oxygen produced
b) The rate of ATP synthesis by ATP synthase in the chloroplast
c) The rate at which NADPH is produced
d) The rate at which the protons are transported into the thylakoid
The answer is; A
The photosystem captures energy from sunlight and uses it to split a water molecule. After splitting the water molecule (by taking an electron), the protein complex transports the electron to plastoquinone. The splitting of water molecules results in evolving of oxygen molecules. The hydrogen is what is used to reduce carbon dioxide to glucose.
