A) Each DNA nucleotide is made up of a sugar, a phosphate group ... Adenine and thymine are connected by two hydrogen bonds, and cytosine and guanine are ... In the case of RNA, the five-carbon sugar is ribose. DNA is made up of two strands that are twisted around each other to form a right-handed helix, called a double helix. Base-pairing takes place between a purine and pyrimidine: namely, A pairs with T, and G pairs with C. In other words, adenine and thymine are complementary base pairs, and cytosine and guanine are also complementary base pairs. This is the basis for Chargaff’s rule; because of their complementarity, there is as much adenine as thymine in a DNA molecule and as much guanine as cytosine. Adenine and thymine are connected by two hydrogen bonds, and cytosine and guanine are connected by three hydrogen bonds. The two strands are anti-parallel in nature; that is, one strand will have the 3′ carbon of the sugar in the “upward” position, whereas the other strand will have the 5′ carbon in the upward position. The diameter of the DNA double helix is uniform throughout because a purine (two rings) always pairs with a pyrimidine (one ring) and their combined lengths are always equal.
Answer:
Explanation:
The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things.
B) Rust, because it has tightly arranged hyphae
6CO2 + 6H20 -> C6H12O6 + 602
Carbon Dioxide + Water = Glucose + Water
Carbon Dioxide is an input of Photosynthesis which is a process mainly plants use to make their own 'food' (organic compounds).
Carbon is removed from the atmosphere and put into food through PHOTOSYNTHESIS :)
