The correct option is D.
Sexual form of reproduction leads to increased genetic diversity as a result of the two different reproductive cells that are coming together and the biological assortment that occur during the process of cell division. Increased genetic diversity enhance variations among living organisms and increased their potentials to survive in their environments.
Answer:
plasma membrane
Explanation:
The plasma membrane is also known as the cell membrane. It is the boundary between the internal components of a cell and its external surroundings. It controls the entry and exit of substances into or out of the cell and thus, facilitates the exchange of substances between the cells and their external environment.
Answer:
Option-1 and 3
Explanation:
Cadherin is the protein complex present in the cell which is responsible for the sticking together of cell in tissue-like in the skin. The cadherin junctions allow the communication between the cells and the loss of the cadherin could cause cancer.
The cadherin junction is involved in the signalling pathway in the cells like in the Rho GTPase signalling, Ras signalling and many others which shows that they are responsible for the biological processes in an organism.
Thus, Option-1 and 3 are correct.
Chopping down trees hurts the environment
Answer: D. offspring with red and green cones.
Explanation:
Codominance is a form of inheritance in which the alleles of a pair of genes in a heterozygous are fully expressed. As a result the offspring phenotype is a combination of the parents' phenotype. Therefore, the trait is neither dominant nor recessive.
In the codominant inheritance, two different versions so called alleles of a gene are expressed and each allele produces a somewhat different protein. Here, both versions influence the genetic trait or determine the characteristics of the genetic condition.
