Answer:
True
Explanation:
Serous membranes are found around organs to lubricate them and reduce friction
Bacteria - eubacteria kingdom - binary fission
blackworms - Oligochaeta - fragmentation
Hydras - hydrozoa - budding
copperheads - Reptilia -<span> parthenogenesiss
Fungi - Hypha - sporulation

btw blackworms, hydras, copperheads. Are all in the Animalia kingdom, the thing in the middle is the class.
Answer:
RNA molecules are made of nucleotides. (Ans. C)
Explanation:
RNA, which is also known as ribonucleic acid is found in cytoplasm of the cell, and synthesized in the nucleus. It is shorter, and a single stranded molecule. It is composed of one or more nucleotides which are linked together by phosphodiester bonds.
In RNA, the ribonucleotide contains pentose sugar ribose, four nitrogenous bases (A,U,C,G), and a phosphate group. RNA plays many types of role in cells, but mainly involved in the translation process, and it's regulation which is known as protein synthesis.
The RNA synthesis or ADN transcription occurs in the nucleus and requires:
- DNA strand to act as a template.
- Enzymes, specially the RNA-polymerase.
- Ribonucleotides of Adenine, Guanine, Cytosine and Uracil.
This consist of three maturation of the 3'-->5' direction while the sense of RNA synthesis is 5'-->3'.
This is fulfilled because the enzyme selects the ribonucleotide whose base is complementary to the DNA chain that acts as a template, and binds it by means of a nucleotide bond, releasing a phosphate group.
The Hardy-Weinberg equation is:
where p generally represents the frequency of the homozygous dominant population.
The q usually represents the frequency of the homozygous recessive population, and the 2pq term represents the frequency of the heterozygous population.
