Answer:
False; The levels of carbon dioxide have significantly increased since the industrial revolution.
Answer No 2:
c c
C Cc Cc
c cc cc
The genotype of the offsprings would be Cc, Cc, cc, cc i.e heterozygous cleft chin and no cleft chin. The phenotype of the offsprings could be 50% cleft chin and 50% without cleft chin.
there will be 50% chance of the child to have cleft chin.
Answer No 3:
A a
A Aa Aa
a Aa aa
There will be 25% chance for the offspring to have arched feet. As arched feet is a recessive trait, so for this trait to occur both the alleles of the gene should be recessive i.e aa.
Answer No 4:
B b
b Bb bb
b Bb bb
As blonde is a recessive trait, so both the alleles for this gene should be recessive for this trait to occur. Hence, according to the punnet square, there will be 50% chance for the offspring to be blonde.
Answer No 5:
F f
F FF Ff
f Ff ff
As normal vision is a resessive trait, hence both the alleles of the gene should be recessive for the trait to occur. According to the punnet square, there is 25% chance that the child will have normal vision.
Answer:
When you heat proteins in water that is 100°C they denatures and the enzymes change shape.

Answer:
B. Jejunum
Explanation:
The segments constituents of the small intestine, in order from stomach to large intestine are: C. Duodenum, B. Jejunum, and E. Ileum.
The statement that is false about base stacking is; B. Stacking interactions are hydrophilic in nature.
<h3>What is the truth about Base Stacking?</h3>
Base stacking is defined as a common arrangement of nucleobases that are found in the three dimensional structure of nucleic acids. Bases (or base pairs) are planar, and these planes stack at contact distance , excluding water and maximizing Van der Waals interactions.
Looking at the given options, the only one that can be said to be false about the defined base stacking above as regards nucleic acids is option B.
The missing options are;
A. Stacking interactions occur when two or more bases are positioned with their rings parallel to each other.
B. Stacking interactions are hydrophilic in nature.
C. Stacking involves a combination of van der Waals and dipole-dipole interactions between bases.
D. Base stacking helps to minimize contact of the bases with water.
E. Base stacking interactions are important in stabilizing the three-dimensional structure of nucleic acids.
