Answer:
Explanation:
Transpiration Transpiration is the procedure of water evaporating from the surface of leaves. Ground water is carried through the roots to the under-side of a leaf, and then comes out through tiny pores. It then evaporates into vapour drops before dispersing into the atmosphere. The rates of transpiration get higher with the higher temperatures.
Answer:
The cladogram is correct. The further explanation is given below.
Explanation:
- As with most other species excluding lamprey, paired arms and legs are established.
- In any organism except lamprey as well as tuna, paired legs become available.
- Throughout all animals, except lampreys, tuna, certain bullfrogs, the amniotic membrane seems to be preserved.
- In kangaroos, rhesus monkeys including people, mammary glands were only ever available.
- The placenta has only been found throughout rhesus monkeys and also in humans.
- Foramen magnum forward will be exclusively found in humans.
Correct answer: D). DNA technology can increase genetic diversity by producing more variant alleles.
The genetic diversity can be increased by the mutation that creates new alleles in the population. The recombinant DNA technology enables the joining of DNA from the two or more than two sources that allow changing the genetic composition of the living organism. The genetic diversity helps the population to adapt to the changing environment.
Hence, the correct answer would be option D.
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:
The swim bladder is located in the body cavity and is derived from an outpocketing of the digestive tube. It contains gas (usually oxygen) and functions as a hydrostatic, or ballast, organ, enabling the fish to maintain its depth without floating upward or sinking.
