creation of mid-ocean ridges
creation of convection currents
formation of rift valleys
Answer:
I believe the answer would be creation of mid ocean ridges
Explanation:
I believe this because the other options dont sound right
Answer:
b
Explanation:
b. Haploid and Diploid
c. alternation of generations
Answer:
The correct answer would be c. alteration of generation.
It refers to the reproduction pattern usually observed in lower plants in which their life cycle alternate between diploid (sporophyte) and haploid (gametophyte) stages.
The sporophyte represents the diploid stage which produces haploid spores through the process of meiosis.
The spored lead to the formation of haploid gametophyte which produces male and female gametes through mitotic division.
The fusion of the gametes leads to the production of a diploid zygote which matures into a diploid sporophyte.
Thus, they alternate between haploid and diploid stages.
Belinda is a 10-year-old elementary school student who has come in for a physical examination. She is 55 inches tall and weighs 120 pounds. Her doctor calculates her BMI at 27.9 (98th percentile for her age). Concerned about her obesity, Belinda's doctor asks about her diet and her physical activity. Her mother reports that Belinda has become "lazy" and does not like to play outside with her friends after school. She says she is more irritable than usual and complains about helping with household chores. Her mother worries that she may be depressed, although she can think of no family issues that may be responsible for this behavior. Belinda sometimes skips breakfast or has cereal and toast in the morning; she takes chips, a juice drink, and a cheese sandwich made with white bread for lunch; and has a toaster pastry or cookies with milk for a snack after school. She doesn't particularly like meat and frequently asks for buttered pasta with cheese for dinner. Belinda says she eats vegetables "when my mom buys them." A blood test reveals a normal hemoglobin level, low serum iron, moderately elevated transferrin, and low transferrin saturation.
b. RNA has uracil, DNA has thymine
c. RNA is single-stranded, DNA is a double-helix
d. all of the above
Answer:
d. all of the above is the correct answer.
Explanation:
These are the main difference between RNA and DNA
thus the all the above(D) options are correct.
RNA and DNA differ in three major areas: the types of sugars they contain, the bases they use, and their structure. RNA contains ribose sugars and the base uracil, while being single-stranded. In contrast, DNA contains deoxyribose sugars, the base thymine, and has a double helical structure.
RNA and DNA, which can both be found in cells, have several significant differences. To answer your question, the correct choice would be (d) all of the above because:
