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.
The answer is glare recovery. This is the speed with which the pupils return to normal when low-light conditions have been restored. Glare recovery denotes to the process in which the eyes recover visual sensitivity succeeding exposure to a source of glare, such as oncoming headlights when driving at night. Prolonged dark adaptation is associated with normal aging and results in decreased visual acuity at night.
Answer:
displacement reaction.
Explanation:
When chlorine gas is passed through a solution of potassium iodide, as a result of this reaction the products i. e. solid iodine and potassium chloride are formed. This type of reaction is called a displacement reaction because in this reaction the less reactive iodine that is attached with potassium iodide is replaced by the more reactive chlorine molecule so the displacement of atoms held so we called it displacement reaction.
Answer:
The correct answer is vasoconstriction has occurred.
Thermal receptors present in the skin sense the cold around the surrounding and stimulates the sympathetic nervous system of the body.
It immediately causes vasoconstriction in the skin, legs, and arms.
Vasoconstriction prevents or decrease the heat loss from the body to the environment.
Decreased flow of blood to the skin and extremities turns the skin pale in color.
Answer: The correct answer is Mitosis.
Mitosis is a type of cell division in which parent cell is converted into two daughter cells having same number of chromosomes as that of the parent cell.
It is divided into the following stages-
1) Prophase- It is the first phase of mitosis in which condensation of chromosomes ( clearly visible chromosomes with sister chromatids) takes place and the nuclear membrane is disappeared.
2) Metaphase- It is the second phase in which chromosomes are aligned at the equatorial plate of the cell and they are anchored by microtubules from opposite poles.
3) Anaphase- It is the third phase in which each sister chromatid of the chromosome is pulled apart ( with the help of microtubules) towards the opposite pole.
4) Telophase- Chromosome decondensation takes place and nuclear membrane is formed so that two nuclei are visible now.
5) Cytokinesis- It is the last phase of mitosis in which division of cytoplasm takes place so that two daughter cells are produced having same number of chromosomes as their parent cell.
