Answer:

♡ hi darling ♡

--  here's your answers

p.s i worked hard finding these

1. Two possible causes of the largest mass extinction aka the Permian-triassic  in earth's history is  asteroid impacts and massive volcanic eruptions. this hurt because of how it destroyed the land and killed some animals and people. it helped us because the emerging supercontinent of Pangaea showed severe extremes of climate and environment because of its great size.

2. The major developments of the mesozoic era all of Earth's mainland same together into the supercontinent of Pangea. The cleavage began with intercontinental separation during the Late Triassic. Pangea had fractured into various subcontinent during that time as well.

3. The Cenozoic Era was divided into 2 periods which wer, the Paleogene and Neogene which are divided into ages. The Cenozoic had seen the extinction of the not bird dinosaurs. They also witnessed the rise of homo sapiens. It is noticeable by the Cretaceous-Tertiary disappearance event at conclusion of the Cretaceous period and the end of the Mesozoic Era.

I had fun finding these parts and putting them together. it's always good to learn something new! i'm glad i'm not too late ♡

Is it possible for plant breeders to develop a true-breeding pink-flowered snapdragon?
abruzzese [7]

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>
