Sorry for your wait! The second choice “ large scale insulin can be produced in relatively lesser time” seems to be the correct answer.

Since this bacteria can produce insulin identical to that which humans make, we could quickly and more effectively produce more of it at a more rapid rate.

I hope this helped! If it did, would you consider marking my answer Brainliest?

After soaking for one hour in a solution of unknown concentration, a slice of potato appears to be very soft and limp. you can d
MAVERICK [17]

If the potato slice becomes soft and limp after soaking for one hour in the solution, the solution is hypertonic.

<h3>What is a hypertonic solution?</h3>

In biology, a hypertonic solution is a solution with more solute concentration than it is found in the sap of any other cell placed in it.

Such solutions have lower water potential than the cells placed in them. Thus, water will readily move by osmosis from the sap of the cells into the solution.

Cells that are placed in hypertonic solutions, therefore, usually end up becoming flaccid as a result of water loss.

So, if after soaking for one hour in a solution whose concentration is not known, a slice of potato becomes soft and limp, it means the solution is hypertonic.

Answer:

750m/s

Explanation:

The wavelength of a wave can be calculated by using the formula:

λ = v/f

Where;

λ = wavelength (m)

v = speed of wave (m/s)

f = frequency (Hz or s-¹)

According to the information provided on the wave in this question, λ = 5m, f = 150Hz, v = ?

v = λf

v = 5 × 150

v = 750m/s

Hence, the velocity of the wave is 750m/s.

True/false mummifying their dead required ancient Egyptians to understand the biological concept of anatomy
yarga [219]
They definitely had to know anatomy, because they removed the organs, and they didn't want to totally ruin the corpses, because they were supposed to come alive in the after life. If their body was butchered, they couldn't enjoy the afterlife. They put their organs in jars, so you would think that they knew anatomy.
