NEET BIOLOGY

Detailed explanation-1: -The rabbits with longer back legs have an advantage because they can run faster and escape the predator. Which will be the most likely effect on the rabbit population? The population will become extinct due to stress.

Detailed explanation-2: -What will most likely occur in the rabbit population due to the introduction of the predator? Faster rabbits will survive and reproduce increasing the average speed of the rabbit population. What best describes a community?

Detailed explanation-3: -Summary: New research that analyzed more than 270 million years of data on animals shows that mammals and birds–both warm-blooded animals–may have a better chance of evolving and adapting to the Earth’s rapidly changing climate than their cold-blooded peers, reptiles and amphibians.

Detailed explanation-4: -Animal Adaptations in the Tundra Biome The animals here tend to have thicker and warmer feathers and fur. Many of them have larger bodies and shorter arms, legs and tails which helps them retain their heat better and prevent heat loss. Many of the birds of the tundra have two coats of feathers to help keep them warm.

Detailed explanation-5: -Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism’s offspring).
