Answer:
The main reason for the production of haploid cells during meiosis is because the two haploid cells will fuse together to make a new genetically different diploid cell that will form the offspring.
Explanation:
In the context of sexual reproduction, meiosis is the process of cell division by which gametogenesis occurs. In this process, diploid cells are used to obtain haploid cells, called gametes.
The reduction of the chromosomal charge that occurs in meiosis is aimed at producing haploid cells —with half of the crosmosomes of a species— so that <u>when the parents' gametes join, they form a diploide cell</u> called zygote.
Zygote is the starting point for the development of a new individual, part of the offspring.
Answer:
9/32 Pink, Tall and Normal individuals Rr Tt Nn
Explanation:
<u>Available data:</u>
- Red color RR
- Pink color Rr
- White color rr
- Normal NN and Nn
- Symmetrical nn
- Tall TT and Tt
- Dwarf tt
1st Cross:
Parental) rr TT NN x RR tt nn
F1) 100% RrTtNn
2nd Cross:
Parental) Rr Tt Nn x Rr Tt Nn
Knowing that these three genes assort independently, then we can infer that the F2 will have the next phenotypic proportions for each gene:
RR= 1/4 Red
Rr= 2/4 Pink
rr=1/4 White
TT + Tt= 3/4 Tall
tt=1/4 Dwarf
NN + Nn = 3/4 Normal
nn=1/4 Symmetrical
- The proportion of the F2 plants that will resemble Rr Tt Nn (Pink, tall, Normal) in Phenotype
Rr= 2/4 pink
TT + Tt= 3/4 Tall
NN + Nn = 3/4 Normal
2/4 x 3/4 x 3/4 = 18/64= 9/32
The Rough ER...
Just think logically, the Rough ER is covered in ribosomes and ribosomes are in charge of protein synthesis (making proteins), so if ribosomes are attached to the Rough ER, then it must help in some way!

Answer:
A rose plant
Explanation:
A rose plant gathers energy from the sun. It uses the sunlight in order to carry out photosynthesis. Plants need the sun's light to create their own energy.
