Answer:

If the alleles are different, the dominant allele will be expressed, while the effect of the other allele, called recessive, is masked. In the case of a recessive genetic disorder, an individual must inherit two copies of the mutated allele in order for the disease to be present

Why is a cell considered the basic unit of life?

vekshin1

Answer:

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That's because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as a clear boundary between the cell's internal and external environments.

A ______________ is a change in matter in which the substances that make up the matter change into other substances that have ph

Eduardwww [97]

Answer:

chemical change.

Explanation:

There are two types of changes in matter: physical change and chemical change.

physical change- it is a change in matter that alters only its physical properties or its physical appearance. This type of change is reversible. For example- freezing of water, the water turns into solid ice and it can be reversed by melting the ice.

chemical change- it is a change in matter that alter its chemical and thus its physical properties. Most chemical changes are irreversible. for example- burning of paper, results in black soot and ashes- Thus changing both physical and chemical properties.

After being warmed by incoming solar radiation throughout the day, the Earth emits _____ radiation, which is trapped near the Ea

enot [183]

There must be a balance between the flow of energy into the atmosphere and the flow of energy out of the atmosphere and back to space.After being warmed by incoming solar radiation throughout the day, the Earth emits infrared radiation, which is trapped near the Earth’s surface by carbon dioxide.This radiation is called thermal radiation.

In maize, a dominant allele A is necessary for seed color, as opposed to colorless (a). Another gene has a recessive allele wx t

Gelneren [198K]

Answer:

1/2 Aa Wx wx (colored seeds, normal starch)
1/2 aa Wx wx (colorless seed, normal starch).

Explanation:

A (colored seed) is dominant over a (colorless)
Wx (normal starch) is dominant over wx (waxy)

Both loci are independent.

A Aa WxWx individual was test crossed (crossed with a homozygous recessive aa wxwx individual).

The homozygous recessive can only produce a wx gametes.
The dihybrid individual can produce two types of gametes, all of them with the same frequency because the genes segregate independently: 1/2 A Wx and 1/2 a Wx

The possible offspring resulting from the combination of those gametes is:

1/2 Aa Wx wx (colored seeds, normal starch)
1/2 aa Wx wx (colorless seed, normal starch).
