Why do you think a growing human population means a mass extinction event for Earth’s animals? Cite your evidence.
Lunna [17]

Hello,

A “biological annihilation” of wildlife in recent decades means a sixth mass extinction in Earth’s history is under way and is more severe than previously feared, according to research. Scientists analysed both common and rare species and found billions of regional or local populations have been lost. They blame human overpopulation and over consumption for the crisis and warn that it threatens the survival of human civilization, with just a short window of time in which to act.

Hope this helps!!!! Happy Holidays!!!! (:

A pea plant that has round seeds has the genotype Rr. It is crossed with a pea plant that has wrinkled seeds and the genotype rr
Mariulka [41]
The correct answer is 50%, or 1/2. We know that round seeds are dominant, since the round pea plant has a genotype of Rr and the wrinkled pea plant has a genotype of rr. If it helps, draw a Punnett square with the two genotypes.

   R  r
r
r

The square works exactly like a coordinate grid. Combine the letters above and beside whichever of the four spaces you chose to find the genotype for that space.

   R  r
r Rr  rr
r Rr  rr

Therefore, 2 out of 4 of the pea plants have round seeds, since a genotype of Rr means that a plant will have round seeds, and 2 out of 4 will have wrinkled seeds, since a genotype of rr means that a plant will have wrinkled seeds. 2/4 simplifies to 1/2, or 50%. Therefore, there is a 50% chance that the offspring will have wrinkled seeds.

Hope this helps!
