Answer:
1. Nuclei
2. is contributed equally
Explanation:
Fertilization is a process which involves the fusion of the two opposite sex gametes during sexual reproduction. The male gamete is known as the sperm while the female gamete is known as the egg.
If we look into the microscopy of the fertilization process, we will find that the process involves the fusion of gametes involves the fusion of the nuclei. This shows that it is the fusion of nuclei in important as genetic material is present in the nucleus. After the fusion, a diploid zygote is formed in which the genetic material is contributed equally by both the parents through gametes.
Answer:
During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls.

The answer is organism.
Reason why:
A species is an environment of related organisms. A community is a population of common goals. A population is a headcount of how many animals there are of one animal kind.
The genotype of the cross is 1 : 2 : 1 ( TT : Tt : tt )
The phenotype of the cross is 3 : 1 ( Tall : Dwarf )
<u>Explanation:</u>
Given:
Cross between two heterozygous tall pea plant
Let the allele of a tall pea plant be represented by T and for dwarf be t
In heterozygous condition, the genotype would be Tt
Cross between Tt X Tt is shown in the diagram inserted.
According to the cross performed:
The genotype of the cross is 1 : 2 : 1 ( TT : Tt : tt )
The phenotype of the cross is 3 : 1 ( Tall : Dwarf )
