The answer is none. carbon has a symbol (c) but there is no symbol for carbohydrates because its not a chemical compound.for example fats or vitamins or minerals
<span>According to a source the answer is B. They save energy and metabolites and help the organisms to respond to the environmental changes.
</span>A genotype is a set of genes in the human DNA responsible for different traits. It represents your complete identity that you will inherit from your parents and ancestors.
<span>On the other hand, a phenotype is how that trait expresses physically, a characteristic, a visible description of your physical features, including height, eye color, overall health, history of diseases, the ability to gain or lose weight fast, what type of food you like, what you enjoy and what you hate. </span>
Homeostasis is a property of an organism or system that allows its to maintain the controlled parameters within normal ranges. Henry Barbour contributed to the understanding of this concept by his delineation of the reactions of the temperature of the body. This is in line with the same concept that was initially proposed by Claude Bernard.
Answer:
Watson and Crick proposed the double helical model of DNA.
Explanation:
- This model says that DNA exist as double helix. It has two polynucelotide strands running in opposite direction i.e the strands are anti-parallel.
- Each polynucleotide strand is made up of several nucleotide liknked together by phophodiester bonds.
- The two strands are not coiled upon each other but the double strand is coiled upon itself around a common axis like the spiral stair case. Here base pairs forms the stairs and backbone of two strands form railing. Back bone contains sugar and phosphate.
- The base pairing is specific, adenine always pairs with thymine and guanine always pairs with cytosine. Thus if we see any base pair, it consists of one purine and one pyrimidine.
- The two strands of DNA thus show complementary base pairing.
- The strands are held together because of hydrogen bonding between the bases in opposite strand.
- One full helical turn involves ten base pairs and the base pairs are stacked 3.4 A apart.
- This form is called as B-form of DNA.
Answer: B) the organelle is removed by lysosomes
