Answer:
B) Two different species of bacteria can share DNA, including antibiotic-resistance genes, during conjugation.
Explanation:
Conjugation is a process by which bacteria can exchange their genetic material between them. So through conjugation, the antibiotic-resistant gene coded by plasmid can be transferred through sex pilus to another bacteria.
So due to conjugation two different species of bacteria can share DNA which can include antibiotic-resistant genes. Therefore, through conjugation genetic variation and evolution are favored in bacteria. So due to this reason conjugation is a very important process in bacteria to spread antibiotic-resistant genes.

Answer:
true
Explanation:
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
The answer is C because C represent plants and plants produce oxygen and absorb CO2
Answer:
This Punnett square shows<u> incomplete dominance.</u>
Explanation:
The homozygous red flower has two dominant red alleles, and these are represented by the letters RR. The homozygous white flower is represented by rr. Their offspring are all heterozygous Rr, and they have pink flowers. This is the first filial generation, or F1. When the F1 generation cross-pollinates, their offspring will be RR, Rr, and rr in a 1:2:1 ratio. Some of their offspring (the F2 generation) will inherit two R alleles, some will inherit two r alleles, and some will inherit both.
