The ozone layer helps prevent harmful UV rays from entering the atmosphere.
"The ability of an organism to react to an environmental input with a change in form, state, movement, or rate of activity" is a definition of Phenotypic Plasticity.
<u>Explanation:</u>
The tendency of one genotype when opened to different conditions, to create more than single phenotype is called as "Phenotypic plasticity".It's the secret to studying human behaviour.
It's the key to human conduct study by laying the foundation to take into consideration the concept that the similar genome and the similar neural architecture will lead to human cultural diversity. For plants whose sessile existence needs them to survive with environmental conditions, this capacity is especially important.
The common name of this organism is hydra.
<u>Explanation:</u>
Hydra is a fresh water organism and belongs to the phylum Cnidarian. They have tentacles around their body that enables locomotion as well as protection from prey. Hydra has the ability of regeneration and the asexual mode of reproduction in hydra is budding.
In the budding process, a small bud develops in the parent body and the bud after maturation gets detached from the parent body and grows into a new individual. Sexual mode of reproduction is also found in hydra.
Answer:
A. I, II, III, and V only
Explanation:
In genetics, an allele refers to the specific form of a gene, which encodes traits. These alleles are usually in pairs in a diploid organism i.e. an organism with two sets of chromosomes. According to Gregor Mendel,
- An allele can either be DOMINANT when the allele masks the phenotypic expression of its allelic pair while the allele that is masked is said to be RECESSIVE.
- Two alleles can also be CO-DOMINANT when the two alleles are neither dominant or recessive over one another but are simultaneously expressed in that particular gene.
- Alleles can also be INCOMPLETELY DOMINANT when one allele is not completely dominant over the other, hence, forms a third intermediate phenotype when in combination with the second allele i.e. in an heterozygous state.
Based on this, an allele can be dominant (I), recessive (II), codominant (III), and incompletely dominant (V).
U just check a few of them and pretty much close the app then they should be cleared :)
