The law of conservation of energy is a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another.

For example: A bowling ball hitting bowling pins. The energy is transferred and no energy is lost.

I hope this helps :)

How do birds digest their food in the absence of teeth?
vodka [1.7K]

Answer:

They have a gizzard to grind the food.

Explanation:

Birds cannot chew since they have no teeth. However, the beak allows them to split very large seeds or swallow them directly.

For their digestion they have a stomach where digestion enzymes are released. Also they have a gizzard that is an organ that grinds the food mechanically. This gizzard usually has small stones inside that were previously ingested and that helps to digest the food.

In summer squash, white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over spher
dangina [55]

Answer:

Genotypic ratio = 16 WwDd: 0

Phenotypic ratio = 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit

Explanation:

This question involves two different genes coding for fruit color and fruit shape respectively. The allele for white fruit color (W) is dominant over yellow fruit color (w) and disk shaped fruit (D) is dominant over sphere-shaped fruit (d).

According to this question, If a squash plant pure-breeding for white, disk shaped fruit (WWDD) is crossed with a plant pure breeding for yellow, sphere shaped fruit (wwdd), the following gametes will be produced by each GAMETE:

WWDD - WD, WD, WD, WD

wwdd - wd, wd, wd, wd

Using these gametes in a punnet square, all of the offsprings will have genotype WwDd, which is phenotypically white and disk shaped fruit.

The genotypic ratio is 4 WwDd: 0

The phenotypic ratio is 16 white, disk shaped fruit : 0 yellow, sphere shaped fruit.
