In which type of study do scientists assess the health status of a large, defined group of people?

iris [78.8K]

Answer:

The probability of the parents having yellow-bellied off-spring is 100% because all the genotypes have a dominant Y.

It is possible for two yellow-bellied numbats to have a green bellied child if they are both hybrid Yy. The probability of the parents to have a green-bellied child is 25%

Why is density a derived unit?

Triss [41]

Density is a derived unit because it's not reported as a pure unit. (A pure unit would be something like kilograms or meters.) In contrast, the units for density are kg/m3. Density is the ratio of mass to volume; mass has the unit 'kilograms' (kg) and the unit for volume is cubic meters (m3).

Density is an intensive property, which means the amount of the material is irrelevant. The density of a substance is constant.

Alja [10]

Answer:

Here's what i think.

Explanation:

Tides can be extremely dangerous, in some places, high tide will flood caves which people otherwise wouldn't notice as flood-able.

The tides can be important because tide can determine if your boat will be smashed against rocks, or if it is safe to dock!

Vera_Pavlovna [14]

Cancer cells can arise in a variety of ways, the most common, however, tends to be genetic mutations.

Genetic mutations can occur during the life of a cell due to outside factors such as:

The food we eat
The environment we expose the cell to
The substances that touch the cell (e.g skin cells)

That being said, the most common time for a genetic mutation to take place is during cellular division. During this time the DNA that encodes the cells is duplicated. Genetic mutations in this DNA sometimes cause the elimination of programmed cell death.

Programmed cell death is what tells a cell when it should stop growing and dividing. This is a regulatory function designed to keep the number of cells at a balance, growing only when needed. As this cell multiplies, this produces an increasing number of cells that will not die. The accumulation of these cells is referred to as cancer.
