Answer: Hey again!
Option (a) is the correct answer.
Explanation:
Elemental form of carbon means the pure form of carbon, that is, carbon is present in its natural form.
An elemental form also means that the pure atoms are not attached to any other atom.
For example, diamond is an allotrope of carbon in which there are only carbon atoms attached to each other and no other atom is present in it.
Whereas methane has carbon and hydrogen atoms attached to each other therefore, it is not an elemental carbon. And proteins include different atoms attached to each other.
Thus, we can conclude that diamond is an example of elemental carbon.

Answer:
B Binary fission maintains genetic continuity because the daughter cells contain the same number of chromosomes as the parent cell.
Explanation:
Genetic continuity ensures that genetic information is passed from one generation to another in correct way so that the resultant progeny has the complete set of genes required for survival. For example, at the end of mitosis, daughter cells should have the same number of chromosomes as parent cell.
Binary fission is a method of reproduction in some organisms like bacteria. It is an asexual mode of reproduction in which the parent cell splits into daughter cells without the process of fusion with another cell. It still maintains genetic continuity because the daughter cells are identical to the parent cell and thus have same number of chromosomes and type of genes.
<span>The minimal amount of nutrients needed every day by healthy people to prevent nutrient deficiencies is called the RDA.
RDA stands for recommended dietary allowances. </span>RDA's are established by the Food and
Nutrition Board of the National Academy of Sciences. There is a term RDI related to this. RDI stands for recommended daily intake.
There are inner part of the stem and outer part of the stem; in a plant the inner part supports the movement of the water and nutrients. You stop the flow of the vital elements of plant growth when you snap the stem and this is the reason why the plant die due to starvation of the nutrients.
Pancreas is an endocrine gland . It secretes lipase as well. lipase breaks down fats into glycerol by the process of emulsification. it secretes hormones insulin and glucagon
