Answer:
Semi-conservative DNA replication:
The semi-conservative model of DNA replication explains that the newly synthesized daughter DNA molecule contains one newly synthesized strand and one parental strand. This model of replication is important and explains the biological significance of replication. The DNA unwinds in this mode of replication.
Conservative model of DNA replication:
The conservative model of DNA replication explains that the newly synthesized daughter DNA molecules has the one DNA helix of parent and the other DNA helix are entirely new. This model does not has a biological significance. The DNA is not unwinds in this mode of replication.
The semi-conservative mode of DNA replication is found in the living organism.
Answer:
Carcinogenic
Explanation:
A carcinogenic substance is able to modify or damage the genome in a way which promotes the formation of cancerous cells. Cell cycle checkpoint proteins are very crucial for the progression of normal cell cycle. They check for any anomaly in their designated step and halt the process if it is detected. Repair mechanism is activated and cell cycle does not progress till the damage has been repaired.
Here, the pollutant alters the structure of these proteins such that they lose their function. They are not be able to stop cell cycle from progressing even if there is some damage in the genome. The cell divides and gives rise to more damaged cells. Eventually these cells lose their normal function and just keep dividing due to which their division rate becomes double of the normal rate. It can ultimately give rise to cancer which is why the chemical is carcinogenic.
Answer:
Earthworms are Invertebrates and or soil Invertebrates
Explanation:
Remedial measures may be taken to promote beneficial organisms, thereby inhibiting the growth of destructive soil organisms...Can do so, because these soil invertebrates live their whole lives(most do) in the soil, adapted to, helping, and benefiting from the environment. Allowing them to act as . defenders for the soil.
