Answer:
Meristematic tissue
Explanation:
Meristematic tissue contains actively dividing cells that result in formation of other tissue types (e.g. vascular, dermal or ground tissue). Apical meristematic tissue is found in buds and growing tips of plants.
Answer: (B)
Explanation: They are asking for a comparison between light waves and sound waves.
A and C is wrong because it only says about sound waves
D only says about sound waves
E is completely wrong because they are affected differently in different mediums.
Disruptive selection describes changes in population genetics in which extreme values for a trait are favored over intermediate values.
Answer:
C. An approximately three-to-one ratio of black to brown coated mice in F2 is accounted for by the black allele being dominant over the brown allele
Explanation:
Assuming the black genotype is BB and the brown genotype is bb.
At F1:
BB x bb = All Bb (black)
At F2:
Bb x Bb = BB (black), 2Bb (Black), bb (brown)
Th ratio of black to brown is 3:1
961 black : 317 brown is approximately 3:1.
Hence, the correct option is C.
<em>An approximately three-to-one ratio of black to brown coated mice in F2 is accounted for by the black allele being dominant over the brown allele</em>
Most of the cells in the human body are diploid.
Diploid is <span>a cell or organism that has paired chromosomes, one from each parent. In humans majority of the cells are </span>diploid<span> and have 23 pairs of chromosomes. The exception are the human sex cells (egg and sperm cells). These contain a single set of chromosomes and are known as haploid.</span>
