Write a hypothesis about whether radiation has the same impacts on coastal areas, forest areas, and desert areas.

Natasha2012 [34]

Radiation has different intensity of impact depending on the area which they are experienced. Excessive amounts of radiation cause abnormalities in the growth of living things, humans, animals, and plants. The intensity of the damage in forest and coastal areas is higher compared to desert areas since more wildlife are present in the two former areas.

Which cellular change in an organism could be inherited be the next generation?

ikadub [295]

In order for a cellular change to be inherited, this change must be present in the male gamete, or sperm or present in the female gamete, the egg or ovum. This is due to the fact that a baby is created from the fusion of an egg and sperm. Therefore, choice 2, the deletion of a single DNA base in a sperm cell of a trout, is the correct answer.

If we think about it logically, cellular changes in other parts of body should not affect the next generation. For example, if mom has skin cancer, it does not mean at all that the baby will have it as well.

A slice of Swiss cheese contains 41 mg of sodium.

larisa86 [58]

Answer:

a. 41 mg equals 0.041 grams.

b. 41 mg equals 0.0014462 ounces

c. 41 mg equals 9.039*10⁻⁵ pounds

Explanation:

You know that a slice of Swiss cheese contains 41 mg of sodium.

a. What is this mass in grams?

Knowing that 1 mg = 10⁻³ g, you can apply the following rule of three: if 1 mg equals 10⁻³ g or 0.001 grams, 41 mg will be equivalent to how much mass in g?

$mass=\frac{41 mg*0.001 g}{1 mg}$

mass= 0.041 grams

41 mg equals 0.041 grams.

b. What is this mass in ounces?

Knowing that 1 mg = 3.5274 * 10⁻⁵ ounces, you can apply the following rule of three: if 1 mg equals 3.5274 * 10⁻⁵ ounces, 41 mg will be equivalent to how much mass in ounces?

$mass=\frac{41 mg*3.5274*10^{-5}ounces }{1 mg}$

mass= 1.4462*10 ⁻³ ounces= 0.0014462 ounces

41 mg equals 0.0014462 ounces

c. What is this mass in pounds?

Knowing that 1 mg = 2.20462 * 10⁻⁶ pounds, you can apply the following rule of three: if 1 mg equals 2.20462 * 10⁻⁶ pounds, 41 mg will be equivalent to how much mass in pounds?

$mass=\frac{41 mg*2.20462*10^{-6}pounds }{1 mg}$

mass= 9.039*10⁻⁵ pounds

41 mg equals 9.039*10⁻⁵ pounds
