Answer
<u>A) Segregation</u>
Explanation:
In Mendel's law of Segregation, each allele is inherited separately from each other within gametes- each gamete can only carry one gene.
Transposons refute this; here, variegation (regions of multiple colors) may occur due to "jumping genes" leading to multiple phenotypic variants like a multicolored seed,instead of a seed retaining one solid color. Mendelian ratios, thus, are not observed.
This is seen in instances such as Indian corn- these seeds may be purple, red, green and yellow. Variegation of seed color can occur to produce multicolored grains of purple and white.
Answer:
caffeine is a stimulant of the central nervous system
Explanation:
Caffeine is a substance that acts on the central nervous system to increase the resting metabolic rate, thereby energy drinks with caffeine can increase the number of calories burned at rest. Energy drinks are generally composed of stimulants such as, for example, caffeine, taurine and glucuronolactone, in addition to substances associated with mental alertness (e.g., B vitamins, panax ginseng root extract, L-carnitine, etc). It has been shown that the overdose of caffeine may be associated with palpitations, high blood pressure, type 2 diabetes (caffeine reduces insulin sensitivity), etc. Moreover, it is also important to highlight that energy drinks generally contain high sugar levels (around 40 grams of sugar for each beverage). In consequence, well-reputed health organizations discourage the use of energy drinks in order to avoid stimulant ingredients and reduce the consumption of sugar-sweetened beverages.
