Answer:

Explanation:

So basically genes are made of DNA molecules. DNA molecules are the building blocks of genes.... if you think about legos for a second the building blocks of legos would be plastic right? because without plastic you don't have legos which is same here... genes are legos and DNA molecules are the plastic that make them (if you get my analogy).

So genes are the information carriers because they carry information on how to make a certain protein or express certain characteristics. Gene directs the cell to make certain proteins and proteins are the key players that are involved in many cellular process because they carry out major functions hence, the protein determine the function of cell because without protein the cell would have no function

What does the plasma do? Name three things.

Vedmedyk [2.9K]

Answer:

Plasma carries water, salts and enzymes.

Explanation:

The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma. The plasma then helps remove this waste from the body.

You are conducting a CRISPR-Cas9 experiment. You transform a cell with Cas9 and a guide RNA (contains the scaffold and guide seq

SOVA2 [1]

Answer:

Cas9-sgRNA cannot align with targeted DNA sequence

Explanation:

Without a PAM sequence, the CRISPR-sgRNA (small guide RNA) complex cannot align with the targeted DNA sequence. Therefore, you cannot perform experiments (e.g. gene editing) using CRISPR-Cas9.

Determining rate in white light. Calculate rate of volume change for Elodea in white light. Record in lab data

Masja [62]

The rate of volume change can be used to find out how different lights (different wavelengths) affect photosynthesis and plant growth. To calculate it, we just need to record data of volume change and time.

------------------------------------------------------

To determine the rate of volume change, you need to use the following formula.

Rate of volume change (mL/hr) = Final volume - Initial volume  x 60

Time

$\\ Rate of volume change (mL/hr) = ((Final volume - Initial volume)/ Time (min)) x 60 (min/hr) \\$

To calculate the rate of volume, we will use the following data.

If these values are different from yours, you just need to replace them acoording to the data in your table.

Time (min) White light volume

0 3

5 4.3

10 5.6

15 6.9

20 8.2

So, according to these values

Final volume, Vf = 8.2 mL
Initial volume, Vi = 3 mL
Time, T = 20 min

Rate of volume (mL/hr) = ((Vf - Vi)/ T) 60

$\\ Rate of volume (mL/hr) = ((Vf - Vi)/ T) 60\\$

$\\ Rate of volume (mL/hr) = ((8.2 - 3)/ 20) 60$

$\\ Rate of volume (mL/hr) = 15.6 mL/hr$

The rate of volume change for Elodea in white light is 15.6 mL/hr.
