Answer:
The correct answer will be option-D
Explanation:
Stem cells are the cells which have the ability to form different types of cells. They differentiate and specializes to perform different functions in the body and thus forms the different cells.
The differentiation and specialization are controlled at the gene level by different patterns of gene expression. The pattern of gene expression is not fully understood during development but research have shown that the gene expression is influenced by the different environmental signals and internal regulators.
Thus, option-D is the correct answer.
Could u possibly give me any options or is it opionon based. let me know ill answer it in a jiffy:)
Pine trees have deep roots which enable them to adapt to the climate of the northwestern coniferous forests. Their roots extend deep down to the soil where oxygen content is limited and water is scarce. During the change of seasons when the soil is wet the roots tend to recede and when it is dry the roots tend to spread downward.
Enzyme deactivation which is called denaturization is when an enzyme's physical structure is changed due to either high pH, or temperature. If enzymes convert the sugar to starch and make the corn less sweet, then boiling the enzymes will cause them to deactivate, which doesn't allow them to convert the sugar into starch. Therefore, the corn will remain sweeter.
Consider that when the enzyme is heated that its physical structure changes, meaning that it may not be able to fit the sugar molecule in its activation site. Meaning that the sugar can no longer bind to the enzyme to create starch, which again leaves it sweeter.
*activation site - site where the substrate (sugar) bonds to the enzyme in order for a chemical change to occur to the substrate.
The clinician recognize that a 49 years old woman is likely to be experiencing is Dyspareunia
Dyspareunia is a painful sexual intercourse due to medical or psychological cause. The pain can primarily be on external surface of the genitalia or deeper in the pelvis upon deeper pressure against the cervix. It can affect a small portion of the vagina or it may felt over the surface.
