Answer:
c. autotrophs and animals are heterotrophs
Explanation:
There's many differences between the plants and the animals, be it their physical appearance, way of live, how do they function, their requirements for survival. One of the major differences between the plants and the animals is that the plants are autrotrophs, while the animals are heterotrophs. The autrophs are the organisms that are able to produce their own food, thus they are producers, meaning that they do not need nutrition from other organic sources. The heterotrophs on the other side are the organisms that are not able to produce food for themselves, but instead they get their food through consuming of other living organisms, making them primary, secondary, and tertiary consumers.
Answer:
41 chromosomes
Explanation:
Cats have a dipoid chromosome number of 38, <u>so their gametes will have half that number: an haploid number of 19 chromosomes</u>.
Rabbits have a dipoid chromosome number of 44, <u>so their gametes will have an haploid number of 22 chromosomes</u>.
When a cat gamete (n=19) joins with a rabbit gamete (n=22) to form the hybrid zygote, it will have 19+22=41 chromosomes. When it undergoes mitotic division, all its somatic cells will have 41 chromosomes.
