Cell organelles are capable of reproducing themselves.
B.
Cells differ in shape, but they have identical components.
C.
All cells begin life as prokaryotic cells.
D.
All living things are made up of cells.
Answer:
D.) All living things are made up of cells.
Explanation:
As the cell theory states, all living things are made up of cells, and those cells are divided into to main categories, being plant and animal cells.

Explanation:
Fertilization bc that's what i got and it was right
DNA replication is the process that must occur first before any cell division can take place.
In order for cell division to take place, a process called DNA replication must occur first. DNA replication is the process by which the genetic material (DNA) is copied to produce two identical copies. This ensures that each new cell will have an exact copy of the genetic material.
DNA replication occurs during the interphase stage of the cell cycle, specifically during the S phase. The S phase is the time when the cell prepares for division by duplicating its DNA.
During DNA replication, the double-stranded DNA molecule unwinds and separates into two separate strands. Each strand serves as a template for the synthesis of a new complementary strand, resulting in two identical DNA molecules.

The correct answer is (C) Erupting volcanoes release many toxic gases.
Air pollutants are gases that harms the environment and human health. Some air pollutants come from volcanic eruption are toxic( like sulphuric acid) and harm our health. Volcanic eruption produce soot and ash into the atmosphere , which reduces sunlight and lowers temperatures. Eruption also produce carbon dioxide, carbon monoxide and other polluting gases
Some other examples of natural air pollutants are:
1. Radon is a radioactive gas that seeps from the ground in some areas, and fog and mist are both dense water vapor at ground level that obscures vision. 2. Ozone, a chemical formed naturally by the action of sunlight on oxygen, is a pollutant at ground level but beneficial in the upper atmosphere. It damages plants and causes breathing problem in the lower atmosphere.
Answer:
The blonde hair would be the recessive trait and both the parents must be heterozygous dominant.
For instance, let us consider B and b the alleles of the gene responsible for the color of the hairs.
B is the dominant allele which codes for the brown color whereas b is recessive allele which codes for blonde hairs.
The phenotype of both the parents is a brown color, that is, dominant trait. They genotype would be Bb.
The cross would produce offspring with three possible types of genotypes BB, Bb, and bb in the ratio 1:2:1.
The offspring with BB and Bb genotype would have brown hair color and the offspring with bb would have blonde hair color.
