The process of passing genetic material from one generation to the next depends completely on how cells grow and divide. To reproduce, a simple organism such as bacteria or yeast simply copies its DNA (through a process called replication) and splits in two. But organisms that reproduce sexually go through a complicated dance that includes mixing and matching strands of DNA (a process called recombination) and then reducing the amount of DNA in special sex cells to arrive at completely new genetic combinations for their offspring.
There are two basic kinds of organisms — ones with a nucleus and those without a nucleus (a compartment filled with DNA surrounded by a membrane called a nuclear envelope):
<span>Prokaryotes: Organisms whose cells lack a nucleus and therefore have DNA floating loosely in the liquid center of the cell. Prokaryotes divide, and thus reproduce, by simple mitosis.</span><span>Eukaryotes: Organisms that have a well-defined nucleus to house and protect the DNA. Eukaryotes divide by meiosis for sexual reproduction.</span>
It would be nitrogen, oxygen, and carbon dioxide (:

<h3><u>Answer;</u></h3>
The above statement is <u>false</u>
<h3><u>Explanation</u>;</h3>
- Rocks have different porosity and permeability characteristics, which means that water does not move around the same way in all rocks below ground.
- Permeability greater than 250 mD are considered very good, while permeability less than 1 mD are considered poor.
- Low porosity normally results in low permeability, but high porosity does not necessarily imply high permeability. It is possible to have a highly porous rock with little or no interconnections between pores.
B) sunlight
Sunlight supports life by providing food and warmth which is needed for the population of practically anything on earth to survive
