Some geological time periods are not represented in the strata forming the Grand Canyon, because the evolutionists believed that there are large "time-breaks". However, others believe that there is "<span>erosion [that] was very rapid, facilitated in many cases by erosion occurring in soft, ‘non-hardened’ rock". This generally leads to evidence of "The Flood", and the like

Answer: The release of inactive form of enzyme is important because when the enzyme will active on its release it can digest the organs and glands from where it had been released to support the function of the enzyme only when it is required to be released and promote its functioning at the target site the enzyme is required to be released only in an inactive state.
Explanation:
Pepsin is a an enzyme secreted by the stomach cells in the inactive form that is called as pepsinogen. The function of the pepsinogen is to digest protein in the food. The activation of pepsin requires an acidic pH maintained by the hydrochloric acid in the gastric secretion of stomach. The pancreatic cells secrete enzyme trypsinogen which is activated into trypsin when it enters into the duodenum of the small intestine by the enzyme enteropeptidase.
Answer:
Transcription of gene A is not affected
Explanation:
A transcriptional repressor is a DNA/RNA-binding protein that acts to suppress gene expression and/or protein synthesis by binding to target sequences. Moreover, a silencer is a DNA region that binds to particular transcriptional repressors in order to suppress gene expression. In this case, the transcriptional repressor is activated by binding to an effector molecule X (e.g., another protein). In consequence, and since the activated repressor-X complex is not more able to bind the silencer of gene A, it is expected that such complex will not be able to affect transcription of the target gene.
Answer;
B) four chromosomes
Explanation;
-Mitosis is a type of cell division that involves nuclear division in eukaryotic cells and occurs when a parent cell divides to produce two identical daughter cells.
-Mitotic cell division produces two daughter cells that are genetically identical to each other, and to the parental cell. Thus, a diploid cell, 2n, (contains two sets of chromosomes), yields two daughter cells that are also diploid.
-For example, in human beings, mitosis takes place in the somatic cells where a parent cell with 46 chromosomes produces two daughter cells each with 46 chromosomes.
Tendril
A tendril<span> is a specialized stem, leaf or petiole with a threadlike shape that is used by climbing plants for support, attachment and cellular invasion by parasitic plants, generally by twining around suitable hosts.</span>
