Molecules in all thing move weather it be a solid or a liquid. the molecules in a liquid are far apart and move slow. the molecules in a solid are tightly packed and continuously vibrate. you can put your hand through water but you cannot put your hand through a steel beam.

Yes, the molecules do move. Although you can't tell, they are always moving. This is because the molecules have little energy. When they have little energy, they move slower. I hope this helps! :)

Answer:

Maintaining Homeostasis. The process in which organ systems work to maintain a stable internal environment is called homeostasis. ... Endocrine system: A high concentration of sugar in the blood triggers secretion of insulin by an endocrine gland called the pancreas.

The normal blood glucose level (tested while fasting) for non-diabetics, should be between 3.9 and 5.5 mmol/L (70 to 100 mg/dL). ...

Blood sugar levels for those without diabetes and who are not fasting should be below 6.9 mmol/L (125 mg/dL).

There are lots of different hormones in the human body that serve lots of different functions, but some are used to maintain homeostasis of various physiological parameters, like blood glucose levels. Blood glucose levels are regulated by two opposing hormones: insulin and glucagon.

Cross a person who does not have freckles and is heterozygous for dimples with a person who has

Alja [10]

Answer:

1. 1/2

2. 1/2

3. 1/4

Explanation:

Let the allele for freckles be A or a while that of dimples be B or b.

A person without freckles but heterozygous for dimples = aaBb

A person who has freckles (whose mother has no freckles) but no dimples = Aabb

aaBb x Aabb

Offspring

4 AaBb - freckled and dimpled

4 Aabb - freckled and non dimpled

4 aaBb - non freckled and dimpled

4 aabb - non freckled and non dimpled

1. Probability that the parents will have a dimpled child = 8/16 or 1/2

2. Probability that they will have a child with freckles = 8/16 or 1/2

3. Probability that they will have a child with freckles and dimples = 4/16 or 1/4
