Answer: "Decreasing the salt concentration of the solution lowers DNA's melting point (Tm)" is not a true statement
Explanation:
Increasing salt concentration would lower the DNA's melting point (Tm), not otherwise.
For instance:
- In 8M urea (8M means 8 Moles per dm3), Tm is decreased by nearly 20°C.
- 95% formamide at room temperature would completely denature the double stranded DNA.
Thus, higher concentration of salts like urea or formamide lowers Tm, not otherwise
True
A genotype is the combination of genes in its DNA of the organism that determines its traits
Explanation:
Gametes from parents contribute different alleles of genes to their offspring. This why gametes carry only one copy of genetic material of the organism. They later fuse to form a zygote with a full genetic copy and capable of developing into an full organism.
Depending on which kind of alleles the parents pass down to the offspring will determine the offspring's genotype. The genotype of the offspring will, on the other hand, affect its phenotype which is the outward characteristic. An example is the sickle cell trait. If both gametes from the parents contribute the recessive alleles of the gene, then the offspring will be homozygous recessive for sickle cell genotype and this will show in the phenotype pf the person who will have sickle cell shaped blood cells.

B!!!!!!!!!!!!!!!!!!!!!!!!!!
The correct answer is: [B]: "decreased" .
________________________________________________________
<u>Note</u>:

In a graph of "coal reserves in the United States" vs. "time" ;
→ the "time" is the "independent variable" that belongs on the "x-axis" .
→ The quantity or amount of "coal reserves in the United States" is the "dependent variable" that belongs on the "y-axis" .
If the graph "slopes downward" ; this would indicate a "decrease" in the amount/quantity of "coal reserves" over "time" .
→ As the value of "x" increases — "time" increases — and; as "x" increases, the value of "y" {the amount/quantity of "coal reserves"} decreases.
→ This would be represented by a "downward sloping" graph;
→ and, among the answer choices given, could indicate that coal production:

→ "decreased" ;

→ which is: Answer choice: [B]: "decreased" .

Answer:
Explanation:
a) the cardiovascular condition is sabacute endocarditis
b) It is caused by a type of streptococcus called streptococcus viridians and transmitted through the opening of the wound
c) rheumatic fever can lead to damage to the heart and this damage allows bacteria to attach itself to the heart. Streptococcus viridians are often caused by bacteria hence there growth can be favorite by rheumatic fever.
d) the nails is used to check the blood stream, and should be check for capillary heamorrhage
e) He would order for BAP- Bacteria Agar plate that is used mostly to classic streptococcal bacteria.
