Answer:
Among the following statements shown, the most accurate concerning the founder effect is that (b) It results when a small population breakers away from a larger one. Founder Effect is defined as the reduced genetic diversity which is most likely caused when a population is descended from a small number of colonizing ancestors.
Answer:B flammability
Explanation:
Its a chemical change because the chemicals in the substance change when being lit on fire (example burning wood)
Answer:
20 ( B )
Explanation:
Given data:
a and b are 10 map units apart
b and c are 20 map units apart
a and c = 30 map units apart
<em>condition </em>; Triple heterozygote testcrossed
number of progeny = 1000
<u>Determine the number of double crossover result </u>
P( crossover between a and b ) = 10/100 = 0.1
P( crossover between b and c ) = 20/100 = 0.2
p( double crossover ) = 0.1 * 0.2 = 0.02
hence number of double crossovers = number of progeny * 0.02
= 1000 * 0.02 = 20
Answer:
A.
Explanation:
In water, the reaction between ammonia (NH3) and Hydrochloric Acid (HCl) is an example of acid-base chemistry. By its chemical nature, the nitrogen in ammonia prefers to be attached to four hydrogens rather than the three it has, so it receives them from the hydrogen from HCl
I think this means that nucleotide sequences at the restriction sites are the same when read forward or backward. Restriction sites, or restriction recognition sites, are locations on a DNA molecule containing specific (4-8 base pairs in length) sequences of nucleotides, which are recognized by restriction enzymes. Palindromic sequence is a nucleic acid sequence on double-stranded DNA or RNA wherein reading 5' to 3' forward on one strand matches the sequence reading 5' to 3' on the complementary strand with which it forms a double strand.
