Answer:
Cell, tissue, organ, organism.
Explanation:
Cells are the basic living unit of all of life and so they make up everything. Once cells bond together to carry out a specific function it is considered a tissue. Tissues make up organs which then make up an organism (like humans or animals).
Answer:
Explanation:
Lets Tan seed be TT
Red seed be tt
A cross between TT ×tt will produce 4 Tt
TT× tt
!
F1 Tt Tt Tt Tt
a. Tan seed is dominant with an allele TT. It effect dominate that of red seed indicating it is a dominant traits while red seed is a recessive traits.
A dominant trait is a traits that is expressed in the phenotype of an organism the F1 generation are all Tan seeds this shows that the trait is dominant.
The genotype of the F1 melon is Tt in a dominant form
The F2 result follows the mendelian principle where segregation occur leading to a phenotypic ratio of 3:1
72Tan seeds:24red seeds
Where the 72 tan seed has the highest ratio and 24 red seeds has the smaller ratio.
Tt ×Tt
!
F2 TT Tt Tt tt
Phenotypic ratio 3:1
Mitosis
Advantages: It enables your cells to multiply quickly and produce sister chromosomes.
Disadvantages: There is little genetic variation, each generation faces the same diseases.
Meiosis:
Advantages: The crossing over of genes during meiosis results in individual variety, which is beneficial to the population's survival.
Disadvantages: It requires the use of two gametes.
