Answer:

DNA can be described as the molecules which carries the genetic code for every individual. The DNA is made up of nucleotide bases which join the two strands of DNA. The sugar and phosphate form the backbone of the DNA.

Genes are the hereditary molecules which are made up of DNA. The alleles of a gene represent which traits will be carried by an organism.

Chromosomes are made up of genes. During reproduction, crossing over of DNA occurs and alleles of the genes assort independently due to which variations occur.

Answer:

The answer to the given question is C.

Explanation:

Natural selection:

The population contains both superior as well as inferior organisms where natural resources are limiting so it will cause competition between organisms. As a result of competition, it will select superiors, and inferiors are deleted and they are given reproductive advantages. Due to this reproductive advantage new population emerges. It is more suitable for the environment.  

Natural selection divides into three parts that are directional, disruptive, and stabilizing selection.  

This is an example of natural selection. Environmental conditions create pressure on the individuals and if they can survive and become fittest, their number increases in the population. This is according to Darwin's theory in the struggle for existence. These organisms survived as the fittest organisms to match climatic conditions.

Stabilizing selection: This operates when features coincide with the optimal environmental conditions and the organisms survive in a population. Stabilizing selection pressures do not promote evolutionary change but tend to maintain stability within the population from generation to generation.  

In the beginning, directional selection - the organism develops characters to survive in response to gradual changes in the environmental conditions. It works on a range of phenotypes existing within a population and exerts selection pressure which moves the mean phenotype to one phenotypic extreme. When the mean phenotype overlaps with the new optimum environmental conditions, stabilizing selection will take over.

What are the applications of dipole moment​
Darina [25.2K]

Answer:

<em>Applications of dipole moment: </em>

<em> </em>

<em>(i) Ionic character can be calculated using the value of dipole moment. </em>

<em> </em>

<em>% of ionic character = </em>

<em> </em>

<em>=100* (Experimental value of dipole moment/Theoretical value of 100% ionized molecule) </em>

<em> </em>

<em>(ii) Geometry of the molecule can be predicted using the dipole moment. </em>

<em> </em>

<em>(iii) Dipole moment is helpful in predicting nature of the molecule. Weather it is polar or non-polar in nature. </em>

After filtering by the nephron, where does the cleaned blood go?
Svetach [21]

Answer:

renal vein

Explanation:

The afferent arteriole collects blood from the glomerulus and extends o the renal tubule where it divides into capillaries that ramify the tubule. This blood is the collected by the venules that join into the renal vein which carries blood away from the kidneys. The filtrate in the collecting tubule becomes urine and trickles down into the collecting duct where it joins urine from other nephrons. The urine then flows into the pelvis via the urinary bladder through the ureter.
