<span>Invertebrate<span>, </span>any animal that lacks a vertebral column, or backbone, in contrast to the cartilaginous or bony vertebrates. More than 90 percent of all living animal species are invertebrates. Worldwide in distribution, they include animals as diverse as sea stars, sea urchins, earthworms, sponges, jellyfish, lobsters, crabs, insects, spiders, snails, clams, and squid. Invertebrates are especially important as agricultural pests, parasites, or agents for the transmission of parasitic infections to humans and other vertebrates. Invertebrates serve as food for humans and are key elements in food chains that support birds, fish, and many other vertebrate species.Apart from the absence of a vertebral column, invertebrates have little in common. Indeed, they are distributed between more than 35 phyla. In contrast, all vertebrates are contained within a single phylum, the Chordata. (Phylum Chordata also includes the sea squirts and some other invertebrate groups.) Invertebrates are generally soft-bodied animals that lack a rigid internal skeleton for the attachment of muscles but often possess a hard outer skeleton (as in most mollusks, crustaceans, and insects) that serves, as well, for body protection.</span>
"Two haploid cells are formed" happens in meiosis during telophase I.
<u>Answer:</u> Option C
<u>Explanation:</u>
The chromosomes are inserted into nuclei during telophase I. The cell now needs to undergo a cytokinesis cycle, which separates the initial cell's cytoplasm into two daughter cells. One set of chromosomes are contained in each daughter cell and called as haploid or half the original cell's overall chromosomes number.
The parent cell has two poles, each with a full haploid set of chromosomes (consisting sister chromatids) when the meiotic process hits Telophase I. A cleavage furrow is formed at this point, splitting the cytoplasm of the cell into a half (cytokinesis). Once the cytoplasm is completely separated, the two originating daughter cells start planning for the second meiotic division.
The advantages of selective breeding can include improved quality and higher ... breeding are positive for humans but an awareness of the disadvantages can help
The scientist is only crossing GGkk with another GGkk...so the only type of plant the scientist can get back is GGkk! (So, green short stem plants). No need for a Punnett Square!
