Oxytocin and alcohol
Explanation:
Oxytocin helps to relax the muscles of the breasts and induce lactation in a breastfeeding mother. This hormone is commonly called the cuddle hormone since it helps to create the social and emotional bond between the child and the mother.
Alcohol clearly inhibits the secretion of oxytocin and breastfeeding immediately after alcohol consumption can reduce lactation and milk intake by the child. Maintaining an interval after an alcoholic drink again leads to delayed breastfeeding. Intoxicating levels of alcohol in breast milk can affect the child’s health.
3 components of DNA,
1. Sugar (deoxyribose)
2. Phosphate group
3. nitrogenous bases
(adenine, thymine, cytosine, guanine)
B) The enzyme has active sites where the substrate binds with the enzyme to form a complex. When the substrate binds to the active site, an induced fit is formed where the enzyme changes its shape in order to better serve the substrate and lower the activation energy of the reaction.
11. c. crossing-over. Notice how one of the bottom arms of each of the gray and white chromosome overlaps with each other, then their genes switch to the other's arm. That's called crossing over, when homologous chromosomes' genes flip-flop with each other.
14. b. meiosis. Gametes are special daughter cells that are either sperm or egg for sexual reproduction. Since genes are shuffled and daughter cells are not like parent cells, this is meiosis. 1 parent --> 4 non-identical gametes.
16. a. centromeres. During late prophase and all of metaphase of mitosis, identical sister chromatids are fused together at the center of the chromosome "X" by what's called a centromere. Then, during anaphase, the sisters are pulled apart, at these centromeres, by spindles attached to centrioles toward opposite sides of the cell.
17. c. Metaphase only. Although late prophase has this appearance of chromosomes, the best answer is probably only metaphase. It's not in anaphase because that's when sister chromatids are pulled apart at their centromeres.
