Fatty acids and glycerol best describes the basic structure of lipids. Fatty acids is one of the major components of triglyceride. It is a form of lipids that is used to store energy. Fatty acids are composed largely of a chain carbon atoms bonded with hydrogen atoms. At one of the ends of fatty acids is called carboxyl group. In terms of number of carbons, they are typically an even numbers.
The effect of chemical pollution on insects living in a pond i think
<h2>Given statement is false</h2>
Explanation:
According to dispersive model of DNA replication,DNA molecules are hybrids of parental and daughter DNA;In this model each individual strand is a combination of original and new DNA
Meselson and Stahl did an experiment on DNA replication using E.coli bacteria
- E.coli was grown in a medium containing heavy isotope of nitrogen,bacteria took up the nitrogen and used to synthesize new biological molecules,including DNA
- It was grown for many generations,the nitrogenous bases of the bacteria's DNA were all labelled with heavy nitrogen
- Bacteria were then switched to light nitrogen isotope and allowed to grow for several generations
- They then measured the density of the DNA using density gradient centrifugation
- This method separates molecules such as DNA into bands by spinning them at high speeds in the presence of another molecule, such as cesium chloride
- Each DNA produced two DNA molecules each with one new strand and one old strand called semi conservative replication(half of the parental DNA conserved in daughter DNA)
- Each DNA strand act as a template for synthesis of new strand
- Hence,dispersive model of DNA was eliminated and semi-conservative model of DNA replication was proved by the above experiment
I believe it is the red blood or platelets cell since white blood cells are trying to defend themselves
B.) Cohesion
Explanation:
The best term that fits the description of the term surface tension of water is cohesion.
Cohesion is the intermolecular forces that holds together the particles of liquids and solids.
- Surface tension is a phenomenon in liquids that causes them to come together more and shrink on the surface.
- Surface tension is made possible by cohesive forces between water- water molecules.
- Adhesion is between different molecules like water and glass.
- In capillary action, a liquid is able to rise up in a column
- Sublimation is a phase change from solid to gas.
