<span>Surfactant, which is a mixture of fatty lipids and proteins are secreted by alveolar type II cells that line the perimeter of the inside of our empty alveolar space and aids in the movement of air and liquids that go in and out of the lungs. These cells may line other vital organs to protect it against outside wear and tear and keep the tissue inside our bodies intact making bodily functions working more smoothly.</span>
Answer:
A
Explanation:
A cell can communicate with nearby cells (paracrine signaling) and with cells far away from them (endocrine signaling). These signalings are dependent on the cell membrane receptors on the cell and their response to ligands that bind to them. An example of close cell communication is that of neurotransmitters in neural synapses. An example of cells communicating with faraway cells is that of the pancreas that produces insulin into the blood. The insulin induces other cells across the body to take up glucose.
I hope this helps and that you have a great day! :)
The commas (,) I used separate the 2 processes
No,yes
Yes,no
Chloroplasts, mitochondrion
Yes, no
Carbon dioxide +water(in the presence of sunlight energy),
Oxygen and glucose
Oxygen +glucose +energy, carbon dioxide + water
Carbon dioxide is used up(photosynthesis), carbon dioxide is produced(respiration)
Light energy, glucose
Released, captured
PHOTOSYNTHESIS
Light energy
CO2+ H2O (——————-> O2+C6H12O6
RESPIRATION
O2+C6H12O6——————> CO2+H2O
exposure to drugs causes mutations which produce drug-resistant populations of microbes.
<h3>What is the effect of using same type of drug?</h3>
Drug-resistant populations of microbes arise when the exposure to drugs causes mutations because this exposure produce resistance which leads to mutation in the organism. Due to this mutation, the drugs did not work on the organism anymore.
So we can conclude that exposure to drugs causes mutations which produce drug-resistant populations of microbes.

Answer:
<h2>mRNA, tRNA, and rRNA are all produced by transcription.</h2>
Explanation:
Trascription is the process through which RNA molecules are produced from the DNA template with the help of RNA polymerase/ RNA pol holoenzyme and various other factors. One strand of DNA works as a template, and according the the sequence in DNA, RNA synthesis occur in complementry way.
All type of RNA (mRNA, tRNA, and rRNA ) molecules are produced by transcription.
