Answer:

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

valentinak56 [21]
Scientists most often produce new genetic variations of organisms by causing mutations with radiation or chemicals and then selectively breeding in order to emphasize the desired traits in the new variations. The Dachshund is an example of this. By breeding two dogs with a similar mutation that caused student legs and elongated backs breeders were able to create a new variation not found in nature.

What happens to the heat and moisture from the ocean?
LUCKY_DIMON [66]

Answer:

The answer is A

Explanation:

When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds.

Elina [12.6K]

Answer:

Glucose: is a simple sugar which is an important energy source in living organisms and is a component of many carbohydrates.

Fructose: or fruit sugar, is a simple ketonic monosaccharide found in many plants.

Deoxyribose: sugar derived from ribose by replacing a hydroxyl group with hydrogen.

Ribose: is a kind of sugar that is produced by the body. It is used as a medicine. Ribose is used for heart disease, mental function, athletic performance, chronic fatigue syndrome (CFS), fibromyalgia, and many other conditions, but there is no good scientific evidence to support these uses.

Use a Punnett square diagram to show why, for each pregnancy, the chances of giving birth to either a boy or a girl are 50-50. E
ikadub [295]

Answer:

Because the offspring of a male and female are always going to be xx, xx, xy, or xy.

Explanation:

Remember that men have different reproductive chromesomes than women. Women have 2 x chromesomes(xx) while men have 1 x and 1 y(xy). These are given down to their offspring.

So we can write the this out in a punnet square as(link down below).

After you see the visual, you will find that the genotypes are xx, xx, xy, xy.

As I said above, women have sex chromesomes xx, while men have sex chromesomes xy. When you match the genotypes on the punnet square with the ones we know from men and women, we find that two of them match with men and two match with female.

So with this, we can conclude that 2/4 of offspring will always be male and 2 will be female. And as you well know 2/4 is 1/2 which is 50%.
