Answer:
1. Meiosis 1.
2. Meiosis 2.
3. End.
4A. The chromosome theory of inheritance states that chromosomes are the main carriers of the genetic factors responsible for inheritance.
B. Body cells have two sets of chromosomes while sex cells have one set. Therefore, when two sex cells meet, they form an embryo with two copies of each chromosomes thereby producing a body cell with the exact number of chromosomes. In essence, meiosis maintains the right number of chromosomes of body cells by creating half the number of chromosomes of sex cells.
C. Meiosis.

Answer:
The dominant phenotypes are Long flagella and one vacuole, and the recessive phenotypes are small flagella and two vacuoles.
Explanation:
As you can see in the attached table
1. For the size of the flagella we gave that:
- 241 organisms have long flagella
- 79 organisms have short flagella,
As there are more organisms with long flagella we can conclude that this is the dominant phenotype while the short flagella is the recessive phenotype.
2. For the number of vacuole we have:
- 247 organisms have one vacuole
- 73 organisms have two vacuole
As there are more organisms with one vacuole we can conclude that this is the dominant phenotype while having two vacuoles a is the recessive phenotype.
Then
Dominant phenotypes = Long flagella and one vacuole
Recessive phenotypes = Short flagella and two vacuoles
(D) Most of the best sites are inaccessible by land transportation, so making roads to them is often prohibitively expensive.
<h3>What is a Reserve?</h3>
A nature reserve, also referred to as a wildlife refuge, a wildlife sanctuary, a biosphere reserve or bioreserve, a natural or nature preserve, or a nature conservation area, is a protected area that is important for its flora, fauna, or features of geological or other special interest. It is reserved and managed for conservation efforts as well as to offer unique opportunities for study and research.
In some nations, government agencies may designate them, as well as private landowners like charities and research facilities. Depending on the level of protection provided by local regulations, nature reserves are classified into various IUCN categories. It is typically subject to stricter protection than a natural park. In laws and official documents, different jurisdictions may use different wording, such as ecological protection area or private protected area.
