The correct opition is ICE CAP MELTING.
Salinity refers to the amount of salt that is found in the water of the sea.
Ice caps usually form in the sea as a result of cold weather. When these ice caps melt, they will add more water to the water in the sea and reduce the salinity of the water.
Answer:Option A
Explanation: The snail breaths in the O2 which will then exhale CO2, therefore the plant will take that and process the CO2 back into O2.
The question is incomplete as it does not have the options which are:
- growth factor receptors
- DNA polymerase
- transcription factors
- enhancers
- nucleosomes
Answer:
Transcription factors
Explanation:
The dioxin is an organic by-product formed from the chemical reaction of the organic compounds.
The dioxin is one of the causes of cancer in organisms and the can acts as teratogen during the development of the prenatal child.
The dioxin shows it affects by binding to specific receptors which can activate the transcription of genes and are thus called transcription factors. The dioxin binds these transcription factor called AH receptors and can cause cancer.
Thus, the Transcription factor is the correct answer.
Option C. Organisms were probably more complex during past eras.
Facilitated diffusion of substances crossing the cell (plasma) membrane takes place with the help of proteins such as channel proteins and carrier proteins.
