Answer:
It is called a variable
Explanation:
The cell membrane is also called selectively permeable membrane for its composition, it is composed of amphipathic lipid, protein and small amount of cholesterol which form a bilayer structure allow only specific substance.
The cell membrane is a thin selectively semi-permeable membrane and act as an outer covering surrounding cell cytoplasm, Proteins and lipids are the major components.
The major lipids are phospholipid, which form a semi-permeable lipid bilayer which have both hydrophilic or water loving head group and hydrophobic or water hating tail group and form bilayer structure.
Hence both group can interact with polar and non polar molecule individually called as amphipathic in nature, Some organelles like nucleus and mitochondria also have its own cell membrane.
The proteins are peripheral, extrinsic and intrinsic type and the function of cell membrane is to protect the cell and maintain the structural integrity of the internal environment of the cell.

The cell membrane is also called selectively permeable membrane for the sole reason being it is selective in nature.
It forms a physical barrier and as a barrier between the cell and the external environment as it allows only selected necessary molecules to pass through it and at the same time prevents entry of unwanted / unnecessary substances.
It also regulates the entry and exit of molecules into and out of the cell.
The cell membrane permits the entry of vital molecules like
water, oxygen, amino acids and glucose into the cell as they are crucial for various life processes and at the same time metabolic waste products are expelled through the cell membrane.

B. by fertilizing their crops with nitrogen compounds
C. by fertilizing with sulfur dioxide
D. by not using fertilizers
b)The moon must be full.
c)The moon's orbit must cross the plane of the ecliptic.
d)The moon's orbit must not cross Earth's penumbra.
The moon's orbit must cross the plane of the ecliptic for a solar eclipse to occur. The correct option is C.
A solar eclipse takes place when the moon passes between the sun and the Earth, causing the sun to be partially or fully obscured from certain locations on Earth.
For this alignment, the moon's orbit must intersect the plane of the ecliptic, which is the imaginary plane defined by Earth's orbit around the sun.
During a solar eclipse, the moon casts a shadow on the Earth's surface, blocking or partially blocking the sunlight.
This can result in a total solar eclipse, where the sun is completely covered, or a partial solar eclipse, where only a portion of the sun is obscured.
Thus, the correct option is C.

glycolysis :) I hope this helped
Pyruvate is produced in the glycolysis stage of cellular respiration, where a glucose molecule is split into two pyruvate molecules. This process occurs in the cell's cytoplasm.
The stage of cellular respiration that produces pyruvate as a product is glycolysis. Cellular respiration is a series of metabolic processes by which living cells produce energy through the oxidation of organic substances. The glycolysis pathway is a 10-step biochemical pathway where a glucose molecule is split into two pyruvate molecules. This process occurs in the cell's cytoplasm. Electron transport chain, Krebs cycle and fermentation are all stages of cellular respiration, but they do not produce pyruvate.
