Answer:
3. extreme
Explanation:
A genetic engineer wants to isolate a gene from a scorpion that encodes the deadly toxin found in its stinger, with the ultimate purpose of transferring this gene to bacteria and producing the toxin for use as a commercial pesticide. Isolating the gene requires a DNA library. Should the genetic engineer create a genomic library or a cDNA library
Answer:
The correct answer is - Yes, the genetic engineer should create a genomic library or a cDNA library.
Explanation:
mRNA isolated from the toxin extracted from the venom gland of the scorpion to create a cDNA library. The cDNA sequence is reverse transcribed by the mRNA that lacks the introns as prokaryotic organisms such as bacteria cannot splice introns.
If the engineer wants to express the toxin in bacteria then he required a cDNA sequence as a genomic clone can not use to clone for making proteins. mRNA should be isolated from the venom gland so it can synthesize cDNA library enriched with toxin protein sequence.

What purpose of transportation? Where does it happen the cell
Answer:
Explanation: How do things move across a cell membrane?
Summary. Controlling the movement of things in and out of the cell is an important role of the plasma membrane. ... Osmosis is the diffusion of water molecules across a membrane. Water moves in or out of a cell by osmosis until its concentration is the same on both sides of the plasma membrane.
The plasma membrane is
Answer:
The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment. ... The plasma membrane consists of a lipid bilayer that is semipermeable. The plasma membrane regulates the transport of materials entering and exiting the cell.
Explanation:
In cellular respiration, the energy for most ATP synthesis is supplied by:
A. High energy phosphate bonds in organic molecules
B. A proton gradient across a membrane
C. Converting oxygen to atp
D. Transferring electrons from organic molecules to pyruvate
E. Generating carbon dioxide and oxygen in the electron transport chain
Answer:
B. A proton gradient across a membrane.
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.
In cellular respiration, the energy for most ATP synthesis is supplied by proton gradient across a membrane.
This ultimately implies that, most adenosine triphosphate (ATP) is formed due to the net movement of protons against a concentration gradient in the electron transport chain.
Imagine that you are trapped within the exclusion zone. As you hike your way out, you begin to feel hungry. Using what you know about biomagnification, which food source would be the
safest? Explain how you know.
a. Mushrooms, fruit, and berries
b. Moose or deer meat.
C. Wolf meat.
d. Eagle meat.
The food sources that would be the safest are mushrooms, fruit, and berries.
What do you mean by Biomagnification?Biomagnification may be defined as the process by which a compound such as toxins, pollutants, etc. increases its concentration in the tissues of organisms as it travels up the food chain.
Mushrooms, fruit, and berries are present at the lowest level of the trophic level because they are autotrophs. Due to their position, they contain the lowest amount of toxins in them, and hence are more safest.
Therefore, the food sources that would be the safest are mushrooms, fruit, and berries.

Which of these is evidence of global warming?
OA. Stable precipitation patterns
O B. Falling global temperatures
OC. An increase in the size of glaciers
OD. Overall rising sea levels
The evidence of global warming is best seen in the overall rising sea levels.
How high are the seas?The average height of the ocean's surface above the surface of the land is referred to as sea level. It is a crucial gauge of climate change on Earth and is influenced by a number of variables, such as variations in global temperatures, ocean currents, and land movements.
This is brought on by the melting of glaciers and polar ice caps as well as the thermal expansion of warming seas. Sea levels are increasing more quickly as the earth heats, which is a direct outcome of global warming.
The other possibilities, such consistent precipitation patterns, declining global temperatures, and an expansion of glaciers in size, are not necessarily signs of global warming.
