Answer:
The correct answer is option a. "Double-stranded regions of RNA typically take on an B-form right-handed helix".
Explanation:
Most of the native double-stranded DNA is on an B-form right-handed helix, following the structure proposed by Watson and Crick with about 10–10.5 base pairs per turn. However, double-stranded RNA does not follow this structure, and most regions have an A-form structure. The A-form right-handed helix have slightly more base pairs per turn, which makes it 20-25% shorter than B-DNA.
Answer:
C. Cheaper than producing electricity from coal oil gas.
Explanation:
Nuclear plants and energy has been proven to be cheaper than most, Low fuel costs have from the outset given nuclear energy an advantage compared with coal and gas-fired plants. Uranium, however, has to be processed, enriched and fabricated into fuel elements, accounting for about half of the total fuel cost.

Explanation:
Due to the increasing temperature in ocean it is more advantageous for start fishes to reproduce asexually because they can regenerate via a process called fragmentation.
In fragmentation, a part of arm or a part of disc is separated from the parent body and grows into a complete new organism; an individual star fish.
Moreover, regeneration is the ability of an organism to renew, or re-grow any part of the body, makes it resilient to environmental fluctuations.
Answer:
C) three eudicots and one monocot.
Explanation:
Flowering plants are generally divided into two based on the number of seed leaves. These are:
- Monocots: <em>these are flowering plants with only one seed leaf. Their leaves are usually long and narrow with parallel veination. Seed germination mode is hypogeal. Their stems are usually flesh and without branches and their roots are usually fibrous. Monocots' flowers are usually trimerous, that is, the flower parts are usually in threes.</em>
- Eudicots: <em>as opposed to monocots, they are flowering plants with two seed leaves. The mode of seed germination is epigeal, leaves are usually broad with net veination pattern and they posses tap root system. Flower parts are usually in fours of fives and their stems are usually wide with branches.</em>
Let us look at which of the 2 groups the bunch of flowers collected by the florist belong:
Lilies have parallel vein - monocot
Wild carrot has large taproot - eudicot
Buttercups has five petals - eudicot
Daisies with two cotyledons - eudicot.
<em>Hence, the bunch of flowers contain three eudicots and one monocot.</em>
The correct option is C.
