Answer: D. It yields chromosomes that contain both maternal and paternal DNA.
Explanation:
The recombination or crossing over is a genetic process. It takes place during the Prophase I of meiosis. The homologous pair align and held together by synapsis. This results in the mixture of genes combination formed from both parents that can be represented as a single chromosome.
If the recombination do not occur then each chromosome will be either 100% maternal or paternal. Thus recombination assures the recombinant chromosomes which consists of genetic material from both parents. Thus the genetic diversity of offspring increases.
They do that so when a shark eats something and crumbs come out of its mouth it eats the crumbs
Some species we see in Alaska and nowhere else in the Wolrd are:
Bats
Shrews
Bears
Seals
White Wolfs

The correct answer is C. The three germ layers.
The feature which is only shows higher invertebrates as compared to lower invertebrates is referred to s the three germ layers.
Germ layers is termed as the primary layer of cells which forms during embryogenesis. Three germ layers which are invertebrates are pronounced as eumetazoans which includes animals.
An example of an animal which produces two germ layers is Cnidarian which are endoderm and ectoderm and makes them diploblastic.
Chordates produce third layer which is mesoderm and makes triploblastic. Germ layers they give rise to all animals organs and tissues under process known as organogenesis.
