Answer: Option B) each parental strand serves as a template for the synthesis of a complementary strand
Explanation:
In semi-conservative DNA replication,
- a parent double-stranded DNA splits in two.
- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate replication of a newly synthesized strand
- the new strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.
Thus, option B perfectly describes semi-conservative replication of dna
<span>If my memory serves me well, meiosis </span>is the process that segregates alleles into gametes for reproduction. It has exactly the same definition.
The correct answer is A. Cerebrum
Explanation:
The motor cortex is an area of the cerebral cortex (outer layer of the cerebrum in the brain), this area is the one responsible for movements especially voluntary ones and including the movement of different parts of the body such as the limbs, the jaw, the tongue, the eyeballs, the neck, etc. Additionally, due to the complexity of the motor cortex, this is divided into three areas located in the same zone that include the primary motor cortex, the supplementary motor area, and the premotor cortex. According to this, it can be concluded the motor cortex is part of the cerebrum as it is located in the cerebral cortex which is part of it (cerebrum).
Answer: d - water forming on the lid under the container
Explanation:
Condensation is the process that describes the change of state of water from gas to liquid. It happens in the water cycle when water vapor gets to the atmosphere and due to the lower temperatures turns into liquid water that then forms clouds.
In the demonstration, the container is meant to be the clouds so when water forms under the container, that is condensation happening because the water vapor has not turned back to liquid after leaving the aquarium water as water vapor.
