All of the above....

I am torn between 'All of the above' and 'another allele masks the recessive allele,' because 'recessive alleles rarely cross over' may not be correct, for 'crossing over' doesn't depend on whether the allele is dominant or not, if they are there they can cross over, it's the gene's position on the chromosome that determines the probability of crossing over.

The one that makes the most sense to me, would have to be B. A would not be a benefit at all. While C doesn't necessarily makes sense as the device is only designed to capture energy from ocean waves. And D doesn't make sense to me in general.

The light reaction of photosynthesis puts carbon dioxide into the form of carbonhydrates
Dima020 [189]

Answer:

hey! hope this helps love!

Dark reaction means that light is not necessary for this part of photosynthesis. In the dark reaction, CO2 from the atmosphere is fixed or becomes part of a carbohydrate dioxide into the form of carbohydrates-organic molecules used as food for the plant. This process is called the Calvin Cycle.

Macronutrients are nutrients that contain inorganic components. <br> a. True <br> b. False
emmasim [6.3K]
This is false, as macronutrients are all made of organic components. Macronutrients are carbohydrates, fats, and proteins. The most basic unit for carbohydrates is glucose. Glucose is an organic molecule with a chemical formula of C6H12O6 which then is broken down by the body to convert it to energy (in the form of ATP). Fats or triglycerides are comprised of fatty acids and a glycerol backbone which can also be used by the body for energy or can be stored for later use. Proteins on the other hand are functional molecules wherein the basic unit for proteins is the amino acid. Proteins are exemplified because they contain nitrogen (CHON). All of which can be used as energy and has specific caloric value per gram (4 kcal for every gram of protein and carbohydrates and 9 kcal for every gram of fat).

Micronutrients are usually inorganic compounds with no caloric value. Usually these micronutrients are essential for maintaining biochemical pathways in the body. For instance, niacin and riboflavin are vitamins that are needed in the production of NAD and FAD which are important for reduction-oxidation reactions in the body (i.e. tricarboxylic acid cycle and electron transport chain).
