DNA replication is Group of answer choices conservative. a one-step process. semi-conservative. not carried out by enzymes. not
Alex787 [66]

Answer:

The correct answer is: semi-conservative.

Explanation:

DNA replication is an important process in which the DNA is duplicated before cell division so each daughter cell can have a copy of genetic material.

DNA replication is <u>semi-conservative because one strand of DNA is new and the other one is the old strand</u>. To replicate itself, the DNA double helix is opened, and then each strand serves as a model for the new strands.

DNA replication is <u>not a one-step process</u>, as it takes several complicated steps in which <u>lots on enzymes participate</u> (like DNA polymerase and DNA helicase).

DNA replication is <u>also carried by prokaryotic cells</u>, though it's a much simpler process.

marusya05 [52]

Answer:

In the gums

Explanation:

Lidocaine is a compound which can be used as a local anaesthetic. This anaesthesia works by blocking the voltage-gated channels which allows the influx of the sodium ions. As the sodium ions do not enter therefore an action potential is not generated in the axons as a result of which no pain is felt in the area.

In the given since the lidocaine is used by the dentist therefore the dentist in order to treat some dental problem must inject the lidocaine in the gums where the sensory receptors of the teeth are present.

Thus, in the gums is the correct answer.

What is true of matter in ecosystems?
Sidana [21]
D.Elements continuously cycle between the physical environment and living organisms.

Ecosystem is encompassing all the life on earth in the physical environment that supports it. An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.  <span> </span>
