The option that is true of genes found on chromosomes is that D. they determine the inherited traits of an organism.
Genes are inherited - so those are the things that we get from our parents and other ancestors. It is easy to determine which of these genes a child is going to inherit - the doctors just need to take a look at the chromosomes, because genes are located there.
Answer:
In plants photosynthesis occurs in two steps light-dependent stage and light-independent stage.
ATP is energy carrier and NADPH is electron carrier and both are produced during the first step from the sunlight as they carry the energy and electron to the next step which is light-independent step. In this step both ATP and NADPH are used in the formation of sugars from carbohydrates.
Therefore, these molecules connect the light-dependent and light- independent reactions of photosynthesis.

Explanation:
To make osmosis happen there has to be a difference in the concentration of solutes, between the inside and the outside of the cell. To valance this difference in concentration, water has to flow towards a place that has a higher number of solutes.
The lipids in the cell's wall make this membrane semipermeable. This allows the passage of specific components only, such as water through aquaporins. Lipids and other elements are of importance in the barrier because they maintain the cell separated from the outside, allowing it to be balanced as regards the different substances that can interact with it.
