Answer:
frontal lobe
Explanation:
There are four types of lobes of the brain: the frontal lobe; the occipital lobe; parietal lobe; and the parietal lobe. Occipital, parietal and temporal lobes control and regulates functions of that has to deal with touch, movement, taste, temperature, and vision.
The frontal lobe, which is the largest lobe, is primarily responsible for cognition and emotional functions.
Answer:
Given:
Number of colonies on plate = 40
Amount of DNA used for transformation = 100ng
Volume of competent cells used = 100ul
Total volume = 1ml (1000ul)
Volume plated for growth = 200ul
The amount of cells transformed per 1 µg of DNA is called the transformation efficiency
(CFU is colony forming units) => (number of colonies on plate/ng of DNA plated) X 1000 ng/µg = CFU/µg of DNA
Amount of DNA used for plating = 100ng * (200/1000)
= 100ng * (1/5)
= 100/5 = 20ng
Efficiency calculation = 40 colonies / 20ng = 2 colonies/ng
(2 colonies/ng) * (1000 ng/µg) = 2000 CFU/ug DNA
Transformation efficiency = 2000 Transformants / ug DNA
= 2 x 10³ Transformants / ug DNA
Explanation:
Efficiency of transformation is highest in the 100 pg-1 ng range, so Low transformation efficiency could be because of high amount of DNA used for transformation.
Based on my observations, the earth rotates from west to east about the axis of rotation. The counter-clockwise rotation of the earth is as viewed from the North Pole star Polaris.
My observations supporting the counter-clockwise rotation of the earth are:
- The Sun rises in the east and sets in the west.
- All celestial objects including the stars and the moon rise in the east and set in the west.
The rotation is the result of the strong geomagnetic field of the earth. It is also responsible for the formation of day and night on the planet.

<h2>
Answer</h2>
The monosaccharides is formed by just bounding of C, H and O.
<h2>
Explanation</h2>
Monosaccharides are simplest molecule or unit in the carbohydrates group which united with each other to form di, tri or polysaccharide structure. As these are the simplest unit in carbohydrates, they are only formed by numbers of carbon, oxygen and hydrogen atoms. The number of atoms in the chain of monosaccharides varies with changing required compound. for example in deoxyribose, one of hydrogen is not present in its structure but present in ribose.
