Genes have two alleles.
Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent. Each pair of alleles represents the genotype of a specific gene.
Fungi is a separate kingdom which include all the species such as molds, mushrooms, and yeasts. Fungi have a cell wall which is made up of chitin. Most of the fungi are multicellular. Thus, the correct option is C.
<h3>What are Fungi?</h3>
Fungi is a separate kingdom of the five kingdom classification. A fungus is any member of the eukaryotic organisms which includes microorganisms such as yeasts and molds, as well as the mushrooms.
Fungi are the eukaryotic, non-vascular, non-motile, and heterotrophic organisms. Fungi may be unicellular or filamentous. Fungi reproduce through the means of spore formation. Fungi exhibit the phenomenon of alternation of generation. Fungi lack chlorophyll pigment and hence cannot perform photosynthesis like plants.
Therefore, the correct option is C.

Natural selection acts for the good of the species. The fittest organisms in a population are those that are strongest, healthiest, fastest, and/or largest. Natural selection is about survival of the very fittest individuals in a population. Natural selection produces organisms perfectly suited to their environments.
Putting it in ice would decrease the flow of blood, aka "numbing the sever," which would not only decrease the loss of blood but the chances of the cells dying.
Answer:
Half of the gametes carry one allele of a chromosome, and the other half carry the other allele.Then, fertilization of an egg by a sperm creates a new individual that now possesses two factors for each trait, just like the parents.
Explanation:
The female gamete is called ova which bear 'XX' chromosome and the male gamete is called as sperm that contain 'XY' chromosome.
Fertilization means the fusion of male gamete with the female gamete, which occurs at the ampulla of fallopian tube.This causes formation of zygote which bear haploid cells.
During fertilization, the sperm is capacitated and is attracted towards progesterone which contain CatSper receptor and helps in increase intracellular calcium level.
The tail of sperm disintegrates after the entry of sperm towards the cytoplasm and cortical reaction takes place.Zygote formation takes place after fusion of perm with the ova.
The sperm undergo capacitation that increase the motility and membrane destabilization occurs.
