Answer is: C. A body cell has 46 chromosomes; a sex cell has 23.

Chromosome is a DNA molecule with part or all of the genetic material of an organism.

Chromosomes in humans are divided into two types:

1) body chromosomes or autosomes.

2) sex chromosomes or allosomes.

When sex cells unite during fertilization, the haploid cells (23 chromosomes) become a diploid cell (46 chropmosomes).

Body cells have 23 pairs of chromosomes (22 pairs of autosomes and one pair of sex chromosomes), giving a total of 46 per cell.

MrRissso [65]

Answer:

See explanation

Explanation:

In the Rutherford experiment, alpha particles were directed at the same spot on a thin gold foil.

As the alpha particles hit the foil, most of the alpha particles went through the foil. In Rutherford's interpretation, most of the particles went through because the atom consisted largely of empty space.

However, some of the alpha particles were deflected through large angles, in Rutherford's interpretation, the deflected alpha particles had hit the dense positive core of the atom which he called the nucleus.

This accounted for their scattering through large angles throughout the foil in all directions.

Which one is a transferable type of energy?
kipiarov [429]

Answer:

E. Kinetic

Explanation:

Kinetic Energy. Energy is transferred from one object to another when a reaction takes place. Energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. For the blue ball to move to the position of the green ball, energy must be given to the blue ball.
