Adjustment knobs are used to focus light in a light microscope
Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
Answer:
1). Prophase: This known to be the first step of mitosis. This phase is denoted when genetic fibres within the cell nucleus known to be chromatin begins to condense and become tightly compacted together.
2). Metaphase: This is known to be the second stage that follows prophase and prometaphase and progrsses to anaphase. Metaphase starts to occur when once all the kinetochore microtubules get attached to the sister chromatid which is brought about by the force generated.
3). Anaphase: At this phase, the centomeres at the centre of the sister chromatids are severed. It ensures that each chromosome receives identical copies of the parent cell’s DNA.
4). Telophase: This is the last phase of mitosis. It occurs when the newly formed daughter chromosomes get their own individual nuclear membranes and identical sets of chromosomes.
The main purpose of mitosis is to accomplish cell regeneration, cell replacement, and growth in living organisms.
The answer is C, because a prokaryotic cell doesn't have a nucleus
Answer:
Pyruvate kinase is the important enzyme that catalyzes the conversion of phosphoenol pyruvate into the pyruvate in the glycolysis cycle. This step generates the ATP molecule.
The regulation of the pyruvate kinase is done by the allosteric regulation and fructose 1,6 biphosphate activates the pyruvate kinase. This regulation is important as it control the metabolites present in different organs. The metabolites like fructose, galactose enters in the glycolysis from the liver after the particlar step of glycolysis.
