Answer:
natural selection and adaptation
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:
A potometer measures water loss from leaves. A bubble potometer measures the rate of water loss from a plant by transpiration. A weight photometer measures the amount of water lost by a plant through transpiration. The washing line method is used to prove that most water loss occurs from the lower surface of the leaf.
potometer' (from Greek ποτό = drunken, and μέτρο = measure), sometimes known as transpirometer, is a device used for measuring the rate of water uptake of a leafy shoot which is almost equal to the water lost through transpiration. The causes of water uptake are photosynthesis and transpiration
They basically do most of the work in the cells and are required for the structure, function, and regulation of the body's tissues and organs. (made up of thousands of smaller units called amino acids)
<span><span>Mitosis is the process in which cells divide to
form new cells. The cell that is being described under the microscope is
already in the Anaphase stage in mitosis.
Anaphase is the process in which two sister chromatids separate and move to
opposite poles of the cell. These two sister chromatids contain identical
copies of DNA that are joined at the middle called centromere. The chromosomes
are separated by the mitotic spindle. Towards the end of the anaphase</span> the two sister chromatids now have their two
separate poles. The mitotic process then proceeds to the
Telophase.</span>
