Population density is the amount of people in one place. Population distribution is the spread of people around the world.
Answer: The options are not given but it is gotten from another websites and here are the options.
A.Cell-to-cell (membrane molecule) recognition
B. Cell junctions
C. Paracrine signaling
d. Synaptic signaling
The correct option is C.
Paracrine signaling.
Explanation:
This is because in paracrine signaling cell communicate with other near by cells through chemical Messengers. It is a form of cell to cell communication in which a cell produced signal and transfer it to other neighbouring cells whereby the neighbouring cells alter or change their behavior to counter the effect of the signal. From the question, the lung cells send signals to neighbouring cells and this alter their behavior by slowering down protein making machinery.
Answer:
d. DNA is used as a template to make a complementary strand of RNA - Transcription
Explanation:
This question is describing the process of TRANSCRIPTION, which is the first process involved in gene expression or protein synthesis. Transcription is the process by which a DNA template is used to synthesize a mRNA strand.
The process of transcription, which occurs in the NUCLEUS of an eukaryotic cell involves making a complementary strand of RNA (messenger RNA) from a DNA template. For example, a nucleotide A (adenine) in the mRNA will pair with a nucleotide U (uracil) on the mRNA.
