Experiments are usually compared against a control group where there was no independent variable applied to the dependent variable.
The statements that correctly describe gestation are: the normal period of gestation is about 40 weeks; the stages of this process include: zygote, blastocyst, embryo, and fetus; and changes to the form of the embryo come from differentiation and growth.
The gestation period in humans lasts about 40 weeks and comprises different stages and processes from conception until birth. The main stages of this process include:
- Zygote: Fertilized ovum.
- Blastocyst: Cluster of cells that is the result of the zygote going through cell division.
- Embryo: Unborn human that is still developing, usually before the 8th week of gestation.
- Fetus: Unborn human in development after the 8th week of gestation.
Moreover, this process implies differentiation as cells specialize for specific functions, for example, muscle cells or nerve cells, and growth as the number of cells increases and therefore the embryo or fetus increases in size.

• Offspring are genetically identical to parent-asexual reproduction
Fungi reproduce asexually on different ways such as fragmentation, budding, or producing spores(asexual spores, which are produced by one parentand thus, genetically identical to that parent).
• Offspring genetically distinct-sexual reproduction
Sexual reproduction introduces genetic In fungi, there are two ways(two mating types):both mating types are present in the same mycelium (homothallic) or mycelia require two different mycelia (heterothallic).
A protist has a nucleus inside of it to make it a Eukaryote, if it had no nucleus it would be consider a Prokaryote
