3. Mitosis
4. Meiosis
5. Meiosis
6. Meiosis
Explanation:
A cell can divide by one of the two ways of cell division which are: Mitosis and Meiosis.
During mitosis, a cell undergoes four stages of distribution of nuclear material which are prophase, metaphase, anaphase, and telophase and easily characterised.
The mitosis division produces cells with the same genetic material called clones and is involved in the division of the somatic cells. This helps in the growth and repair of the damaged tissue.
Meiosis type of cell division divides and form the four haploid cells from parental cells. The process produces haploid cells in two stages: Meiosis I and Meiosis II. The tetrad formation takes place during the prophase I of the meiosis I.
The integumentary system (skin) reacts different on different sun intensity (different length exposure to sun).
For example, moderate exposure to the sunlight contributes to the production of melanin and vitamin D by the body. On the other hand, high exposure to sunlight can have negative health effects such as sunburn, which is an inflammatory response to DNA damage caused by UV radiation.
Answer:
No.
Explanation:
Pink flower colour in snapdragon is as a result of incomplete dominance. The pink flower colour has no allele in nature. Instead, the pink colour results from incomplete dominance of the allele that codes for red flower colour over the allele that codes for the white flower colour.
Assuming that the allele for red flower colour in the plant is R and the allele for white flower colour is r, true breeding red and white flower colour plants will have the genotype RR and rr respectively. In heterozygote state (Rr), the phenotype is usually pink, showing that the R allele has incomplete dominance over the r allele.
<em>Hence, there is no way for plant breeders to develop a true-breeding pink-flowered snapdragon. without some genetic manipulations/mutation.</em>
