Answer:
b, a, d, c, e
Explanation:
The lac operon is called lactose operon is a cluster of genes with a promoter. The bacteria uses lactose as the source of energy by the proteins coded by genes. This is present in prokaryotes.
The regulatory gene codes for repressor protein. The repressor binds to lactose and prevent its binding to operator. In the absence of lactose repressor gets activated and binds with operator. Thus, RNA polymerase is prevented from binding the promotor. The transcription of genes inhibited. Thus correct order is b, a, d, c, e.
PCD would make concieving children difficult because the fallopian tubes cannot push an egg out in order for the sperm to fertilize it
Answer:
Q9 is Elliptical and Q10 is sideways i think. Im not sure. Sorry if its not correct.
Explanation:
The correct answers are gluconeogenesis and glycogenolysis.
Glucose is the prime energy source, which is utilized by the body. Glucagon refers to the peptide hormone, which enhances the levels of glucose in the body when its amount is critically low in the blood.
The upsurge in the number of glucose levels in the bloodstream is encouraged by the processes, gluconeogenesis, and glycogenolysis. Gluconeogenesis refers to the metabolic pathway, which generates glucose molecules, this generally occurs in the liver.
Glycogenolysis refers to the biochemical dissociation of glycogen molecules to glucose. It takes place in the liver tissues.
Answer:
water is essential for life as we know
Explanation:
Water (H2O) is essential for life (i.e. carbon-based life) because this molecule has unique chemical properties. First, water is a universal solvent that helps cells to transport and use essential molecules (e.g., oxygen and nutrients). Second, water molecules help cells to maintain their shape/structure by generating pressure within the cells. Third, the polarity of water helps the formation of phospholipidic membranes because phospholipids have polar heads that interact with water and nonpolar tails that interact with each other. Fourth, water has a high heat capacity, thereby helping to regulate the temperature in the (intracellular) environment. Finally, water molecules also have unique adhesion and cohesion properties that enable the movement of substances against gravity (adhesion) and create a surface tension (cohesion) that helps to the formation of bubbles with water.
