The acidic environment of the lysosome and the lysosomal enzymes detach the ligands from their receptors.
Receptor-mediated endocytosis is a process in which cell surface receptors are employed for transporting substances such as proteins, hormones, and metabolites from extra-cellular matrix into the cells. Receptor-mediated endocytosis usually occurs through clathrin (a type of protein)-coated pits and vesicle and it allow only the receptor-specific substances to enter the cell. Under this process, molecule binds to protein receptors after which the receptor molecule moves to clathrin coated pits and vesicle. The cell membrane then folds inwards and there is fusion of a coated vesicle. After this, the ligands are detached from their receptors.
Gram staining
Gram-positive turns pink or red
Gram negative turns dark blue or purple
Answer:
Yes.
Explanation:
Yes, the structures and functions of the central nervous system work to help prevent injuries with the help of bone. The main line of defense of central nervous system is the bones of the skull and spinal column, which create a hard physical barrier to injury. If these line of defense are not present for central nervous system so it has more chances to get injury so we can say that the structures and functions of the nervous system helps to prevent injuries.
Work is force x distance.
Answer:
The correct answer is option C, that is, in the mother in meiosis II.
Explanation:
A nondisjunction in meiosis I produce all the aneuploid gametes, while nondisjunction at meiosis II produces 50 percent aneuploid gametes and the 50 percent normal gametes comprising haploid number of chromosomes.
As it is mentioned that one of the brothers possess normal number of chromosomes (46), the mother encounters nondisjunction at meiosis II resulting in the formation of one n+1 gamete exhibiting two copies of X chromosome. Fertilization of this n+1 gamete with sperm results in the creation of zygote (47, XXY).
