Monosaccharides<span> (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars. Other carbohydrate molecules are very large (polysaccharides such as </span>starch<span> and cellulose).</span>
Answer:
D. The first division will reduce the number of chromosomes by half for each daughter cell, and the second division will move single chromatids to each daughter cell.
Explanation:
Gametes are formed by meiosis in diploid gamete mother cells. During gamete formation, the gamete mother cell in the yeast would undergo meiosis I. During first division (meiosis-I), the process of crossing over during prophase-I creates genetic variations and movement of homologous chromosomes to the opposite poles during anaphase-I reduces the chromosome number to half in each daughter cell.
Two daughter cells are formed by the end of meiosis-I each of which enters meiosis-II. Splitting of centromere and separation of sister chromatids during anaphase-II of meiosis-II results in the movement of single chromatids to the opposite poles of the cells.
Examples: plant & animal cells, sperm & ovum, bacteria & virus
Because there was a mutation in the gazelle's genetic code. It will be nice for the gazelle to run faster, but since the gazelle was born with longer legs, we know it's just a random mutation. The gazelle's parents have little to do with it, and the nutrition of the food it eats after it's born is irrelevant to how long its legs are at birth.
Answer:
A plant’s ability to photosynthesize depends on a variety of factors, including the amount of available sunlight. Plants also go into a protective mode after an environmental crisis, which helps protect the plants’ chloroplasts from damage. During this period, photosynthesis is low. The technique used in this research improved the plants’ ability to recover after a crisis, boosting plant growth and crop yield. This research could ultimately lead to growing crops successfully in different types of environments and in a shorter period of time.
