Which of the following terms are used to indicate that cell membranes will allow only certain molecules to pass through without assistance?
A. Selective Permeability
B. Open Bilayer
C. Homeostatic Membrane
D. Temporary Permeability
Answers
The plasma membrane separates the cell from the outer environment. It only allows the movement of certain molecules through selective permeability. Thus, option A is correct.
What is selective permeability?Selective permeability is the property that allows the movement and transportation of the molecules inside the cell through active or passive transportation.
It is seen in the plasma or the cell membrane of the cell as it allows only certain specific molecules to enter or leave the cell. It is important for the protection of the cell.
This allows the exchange of the nutrients and waste produced in and out of the cell. The selective permeability is the semi-permeability that is due to the lipid bilayer of the membrane.
Therefore, option A. the cell membranes are selectively permeable.

Pilar just won a coveted award at work, even though many of her colleagues told her she didn't have a chance of getting it. While standing on the stage at the company's banquet dinner, she wanted to gloat and call out the people who didn't support her, but she knew this would not be appropriate. Instead, she stayed positive and smiled, thanked all of her colleagues, and graciously accepted the award. Pilar ended up conforming to this particular social setting's _____.
Answers
Answer:
Pilar ended up conforming to this particular social setting's negativity.
Explanation:
Pilar's co-workers do not show support for the causes in which she participates, on the contrary, they underestimate her and denigrate the capacities she has and the possibility of being rewarded for the hard work she intends to do. This does generate an environment full of negativity, which can harm everyone involved. The fact that Pilar, overcoming this environment, winning the prize and giving a sincere speech, regardless of what her colleagues said, shows that she got used to and adapted to a place with this type of negativity.

Which of the following is NOT a source of nitrogen that is available to plants?
Answers
Answer:
I CANT SEE THE FOLLOWING BUT I WILL EXPLAIN.
Explanation:
Plants usually absorb nitrogen from NO3- and NH4+
Nitrogen oxides released into the atmosphere by burning fossil fuels and organic matter is not a source of nitrogen which is available to plants. Thus, the correct option is D.
How does plants take nitrogen?Plants require nitrogen as it is a macronutrient. The deficiency of this nutrient can cause many diseases. However, plants cannot themselves obtain the nitrogen from air but they rely mainly on the supply of combined nitrogen atom in the form of ammonia molecule, or nitrate molecule, resulting from the nitrogen fixation through free-living bacteria in the soil or the bacteria living symbiotically in the nodules on roots of legumes.
Plants can take nitrogen through absorbing the soil by their roots. Plants cannot get this nitrogen directly from the air. Although, the nitrogen element is abundantly available in air. Nitrogen is unreactive atom, and it cannot be used by the green plants to make proteins. Nitrogen gas needs to be converted into nitrate compounds in the soil through nitrogen-fixing bacteria in soil, root nodules or lightning. Every nitrogen atom is triple-bonded to another nitrogen atom to form the molecular nitrogen, N₂.
Therefore, the correct option is D.
