Answer:
0.1m/s
Explanation:
The speed, which refers to how fast an object moves within a period of time, can be calculated as follows:
Speed (m/s) = distance (m)/time (s)
Based on the provided information in the question, distance = 10m, time = 100s
Hence, the speed will be:
Speed = 10/100
Speed = 0.1m/s
 
        
             
        
        
        
Answer:
a. The directionality of the complementary strand is antiparallel. The double-stranded DNA is antiparallel comprising two strands, which run alongside each other, however, point in reverse directions. In a double-stranded molecule of DNA, the 5 prime ends of one strand align with the 3 prime ends of the other strand, and vice versa.  
b. The mediation of base pairing is done by non-covalent hydrogen bonds. It is reversible, that is, the strands can separate and can come combined again without any chemical modification.  
The specificity of base pairing is illustrated by hydrogen bonds that is, the first strand produces hydrogen bonds only with a particular base in the second strand, and these two bases produce a base-pair.  
c. The interaction or association of non-covalent type, that is, hydrophobic interaction and hydrogen bonding. Collectively, they both are strong. In the process, one base associate with the other base on the complementary strand.  
d. The phosphate backbone possesses the tendency to associate with water on the outside of the molecule, and this is favorable chemically as both the strands are held together by hydrogen bond and hydrophobic interaction.  
The polar molecules of sugar can produce hydrogen bonds with the surrounding molecules of water. The negatively charged phosphate group associate with the positively charged ions. The nonpolar nitrogen bases are found within the molecule and associate favorably through stacking interactions.  
 
        
             
        
        
        
Answer:
Yes 
Explanation:
Because dominate always tops recessive, recessive isn't as popular as dominate traits.
 
        
             
        
        
        
Answer:
A. It contributes to global warming
Explanation:
- Solar power is the power of the future and is an essential nonrenewable source of energy for man. Solar power is driven by the incoming solar energy in the form of solar rays.  
- Solar power is eco-friendly and doe not cause any harm can be sued in the summer season and has ample scope for greenhouse gases. 
- As per the statement, the solar power should be used as the main energy source in U.S can be contradicted by saying it contributes to global warming.
 
        
             
        
        
        
Answer:
B
Explanation:
CRISPR-Cas9 is a gene-editing mechanism that is harnessed from bacteria’s immune system used to cut apart foreign genetic material such as that of bacteriophages. CRISPR-Ca9 has a guide sequence that is used to identify the target sequence. The Cas9 enzyme cuts this target DNA and is replaced with the required piece.
In cancer treatment, the mutated DNA can be replaced, this way, with the wild type.
