1 The Earth's Moon has considerably less mass than the Earth itself. Not only is the Moon smaller than the Earth but it is only about 60 percent as dense as Earth. Thus the gravitational attraction on the Moon is much less than it is here on Earth and a person weighs less on the Moon
2 The strength of the gravitational force between two objects depends on two factors mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled the force of gravity between the objects is doubled increases, the force of gravity decreases.
3 If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power).

Answer:
Phosphodiester bonds:"It is a co-v-a-l-e-n-t bond in which a phosphate group joins adjacent carbons through ester linkages."
- The 3’-end has a free hydroxyl group at the 3’-carbon of a sugar, and the 5’end has a free hydroxyl group or phosphate group at the 5’-carbon of a sugar.
Explanation:
Option- E: Is The best option to Choose from.
The phosphodiester bond links a 3' carbon to a 5' carbon in DNA and RNA.
Answer:
False
Explanation:
Rearrangements on introns and transposons usually don't cause severe consequences because those sequences are not part of coding genes and therefore cannot code for proteins, and if a rearrangement occur within a coding sequence of a gene might cause an incomplete and non-functional protein causing severe consequences to expression levels of that particular gene.
The correct sequence is:
a) Antibiotics: These antimicrobial drugs used to treat and prevent bacterial infections.
b) Antibiotic resistance: This sort of resistance occurs when bacteria are fully developed into the body and are able to defeat the drugs which designed to kill them. When certain bacteria become resistant, the antibiotics are unable to fight them, and hence they increase and affect the body.
c) Binary fission: Binary fission is a sort of asexual reproduction in prokaryotes such as bacteria. It is found in unicellular eukaryotes like Amoeba and Paramecium.
d) Conjugation: It is the transfer of genetic material between bacterial cells by the direct or bridge-like connection between cells.
e) Mutations: is a permanent alteration in the DNA sequence resulting in a gene, such that the sequence differs from the sequence found in human beings.
f) DNA replication: is the biological process that occurs in all living organisms to produce two identical replicas of DNA from a DNA molecule.
g) Genetic recombination: During this process, offspring are produced with the combinations of traits that are different from the traits found in either parent.
h) Genetic variation: It’s the variation in the DNA sequence in each of human genomes, making every human being unique in terms of hair color, skin color or the shape of their faces.<span>
