<span>Water in the surface zone of the ocean is, for the most part well-mixed.
Zones are also known as layers. Ocean is divided into five layers:
Epipelagic zone (The sunlight zone), Mesoplagic zone (The Twilight zone), Bathypelagic zone (The midnight zone), Abyssopelagic zone (The Abyss) and Hadalpelagic zone (The trenches).

<h2>Function of Biotechnology</h2>
Explanation:
- <em>Biotechnology,</em> regularly abbreviated to biotech, is the zone of biology that utilizations living procedures, organisms or systems to manufacture products or innovation planned to improve the nature of human life
- <em>Biotechnology, as other cutting edge innovations, has the potential for misuse </em>
- Biotechnology is the utilization of<em> natural system,</em> found in organisms or the utilization of the living beings themselves to make innovative advances and adjust those advances to different various fields
- <em>These remember applications for different fields from farming practice to the medical sector</em>
Answer:
e. 1.6 ml
Explanation:
Gel cut weight = Weight before addition of gel - Weight after addition of gel = 1.895 g - 1.359 g
= 0.536 g
You need to add 3 volumes of QG buffer to 1 volume of Gel cut PCR product to completely dissolve the DNA.
Volume of QG buffer = 0.536 g X 3
= 1.6 g (1 g is approximately 1 ml)
= 1.6 ml
Answer:
A number of chipmunks die due to old age.
Explanation:
A mutation is any genetic change in the genome of an organism. When a mutation occurs in germline cells it may be passed from one generation to the next, thereby changing the gene pool in a population. Moreover, gene flow is the transference of genetic material among populations, which also have the potential to modify the gene pool in a population. Gene flow may be caused by the movement (migration) of individuals from one population to another and further reproduction of these organisms. Both mutations (i.e., germline mutations) and gene flow (i.e., migration) are evolutionary forces capable of changing the gene pool composition of a population. On the other hand, a pesticide that causes the death of many individuals may also potentially alter the gene pool in a population. Finally, old individuals that death by age are not expected to modify the gene pool of a population (since these organisms don't reproduce).
Answer:
11. Float
12. Bacteria
13. Polymer.
14. Hydrogen.
15. Water.
16. Climatic.
17. Prokaryotic.
18. Length.
19. Large.
20. Frequency.
Explanation:
11. Damaged seeds would float on top of water. This is because they are typically empty and as such lacking in any form of nutrient.
12. Cholera is caused by bacteria. This bacteria is scientifically called Vibrio cholerae.
13. Like synthetic fibre, plastic is also a polymer.
14. Metals react wih acids to produce hydrogen gas.
15. The Fire produced by oil cannot be controlled by water.
16. Migratory birds fly to far away places because of climatic changes.
17. Cell without well organised nucleus are called prokaryotic cells.
18. Time period of a pendulum depends on its length. Thus, the time period of a pendulum is directly proportional to its length i.e as its length increases, the time period also increase.
19. The size of pupil becomes larger when you see in dim light.
20. Shrillness of a sound is determined by the frequency of vibration. A shrill sound refers to a type of sound that is typically sharp, high pitched and as such has higher frequency.
