Answer:
double helix
Explanation:
Deoxyribonucleic acid, commonly known as DNA, consists of two long polynucleotide chains composed of four types of nucleotide subunits i.e. A, G, C, T. Each chain is called a strand. Each nucleotide is made up of a pentose sugar, phosphate group and a nitrogenous base.
DNA is a double-helical structure that contains each strand in a spiral or coiled form. This double helix structure forms when two complementary strands are held together by hydrogen bonds. The bonding occurs between the nucleotide base portions of the complementary strands e.g G-C, A-T.
Answer:
B
Explanation:
process of elimination. The other ones were wrong tbh. Also, in natural selection genetic variation/mutations are a HUGE FACTOR according to darwins 3 principles of evolution.
Answer: The answer is BIOTIC
Explanation: I SHOULD BE BRIANLIEST ;)
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) = <u>Final volume</u><u> - </u><u>Initial volume </u><u> </u> x 60
Time

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.
<u> Time (min) White light volume </u>
0 3
5 4.3
10 5.6
15 6.9
<u> 20 8.2 </u>
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



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