A chromosome is a piece of protein that is inside a cell's Nucleus that contains genetic information. DNA is inside the chromosome, which gives the chromosome the genetic information
A selective permeable membrane sac filled with water and large molecules of starch is suspended in a break of distilled water then water will enter into the sack and it will swell.
This is the process of osmosis in which movement of water molecules form a solution with high concentration to lower concentration till the equilibrium attain. Starch does not pass through thee selectively permeable membrane.Water moves from outside if the cell to the inside leading to swelling of cells.
Small molecules diffuse faster than larger molecules through a membrane. The movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute.

A heterotroph is an organism that relies on complex organic substances for nutrition. <span>A </span>heterotroph<span> is an animal that can't make its own food supply, so they have to eat other things, like plants or other animals, to survive. Hope this answers the question.</span>
<span>Energy transfer is the
transmission of food energy from organism to the next which is illustrated as
the food chain. Normally and typically, the autotrophs are the photosynthetic
organisms that primary makes food for itself and for other organisms.
</span><span>Hypothetically, we can assume that about 6000 kilocalories per square meter per
year these autotrophs can collect and store energy.</span><span> Primary consumers like
omnivores such as deer, cow, birds and etc. receive almost 10% as much from
these autotrophs. </span><span>Secondary consumers receive for as much as 1% of the total
energy that was from the autotrophs.

A.) Sunlight
It is not a biotic factor. It is an abiotic factor.
Biotic factors include plants, animals , fungi, algae, and bacteria.
Abiotic factors include sunlight, temperature ,moisture ,wind or water currents , soil type, and nutrient availability.
