<h2>Part 1.</h2><h2>Answer:</h2>
Only the traits or allele for the green trait will be needed to make a green cucumber.
<h3>Explanation:</h3>
Here in the given example there are two allele responsible for the color of cucumber. One is Y which is dominant allele and codes for the yellow color.
While y is recessive allele and it will be code for the green color.
In case of heterozygous in which the genotype will be Yy but the phenotype will be always yellow because Y is dominant.
In case of genotype yy the phenotype will be green.
So for green cucumber there will be two y in the genotype.
<h2>Part 2.</h2><h2>Answer:</h2>
For yellow cucumber, there is need of only one dominant allele which codes for yellow.
<h3>Explanation:</h3>
According to the given punnet squre, There will be 4 genotypes from the breeding of a yellow cucumber and green cucumber.
The yellow cucumber is heterozygous or homozygous and its genotypes can be Yy and YY relatively.
But for green cucumber the genotype can only be homozygous which is yy.
In the punnet squre the 2 phenotype are yellow and green.
Hence for the yellow cucumber there is only need of one Y allele in genotype.
Secretion helps in moistening the food, making it easier to swallow and preventing oral infections.
Diffusion is the passive transport from a high concentration to a low without using energy. homeostasis results from balance.
<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>
