Answer:
3, 1, 4, 5, 2
Explanation:
DNA helicase enzyme will unwind DNA into 2 segments for a template. Complementary nitrogenous bases will attach themselves to one of the DNA strands. mRNA carries codons for instructions from DNA. mRNA leaves the nucleus and joins with a ribosome (tRNA) in the cytoplasm. tRNA has anticodons which are complementary to a specific mRNA molecule. tRNA pairs with and translates instructions that the mRNA is carrying. Each amino acid delivered to the ribosome by tRNA begins forming a chain of amino acids, called a peptide bond.
If it’s referring to sea floor spreading then the answer is D, I hate analogies but I think it’s talking about the mantle convection that slowly breaks away at the lithosphere
Answer:
The heterotrophic protists would since they use them to gather food.
Explanation:
The most appropriate of the options is heterotrophic protists because these are the protists such as paramecium which are not able to prepare their food themselves. Therefore, they need to use cilia to make a current that brings food sources near their oral groove that makes a connection with cytopharynx. The cytopharynx is a structure that helps in the ingestion of food into the mouth like part called cytostome . This serves as an opening point for the food entrance.
Food upon entering into the cytosome moves to get into the food vacuole where efficient enzymes for the breakdown of food are present. The smaller food components are used by protists as nutrient and ultimately energy source.
The waste product or undigested food are removed from the body of paramecium through structure similar to anus called cytopyge.
<em>Please see attached image of paramecium for better insight.</em>
Hope it help!
Mitosis occurs in every cell of the body except in germ cells which are produced from meiotic cell division.
As a result of its involvement in a reaction, an enzyme is unchanged.
Enzymes are catalysts that speed up chemical reactions that occur within the biological systems (they increase the reaction rate by lowering its activation energy). Enzymes react with substrate that binds to them (key-lock mechanism) and convert the substrate into the product. Most of enzymes are proteins by their structure but a few are catalytic RNA molecules-ribosymes.
Enzyme activity can be affected by other molecules (activators and repressors), pH, temperature etc.
