Answer:
D. The reaction will release energy the organism can use to do work.
Explanation:
A negative ∆G means that the products have less free energy than their reactants. This energy had to go somewhere, it can't just disappear. That means that 255kJ of energy was released, turning into free energy for the organism to use for work.
Answer:
A mass of nutrients enters a stomach full of strong, hydrochloric acid. The acid gets rid of all of the waste material, which is then expelled.
Explanation:
Answer:
Alveoli are tiny, balloon-shaped air sacs. Their job is to move oxygen and carbon dioxide (CO2) molecules into and out of your bloodstream.
Explanation:
Answer:
As rust or iron oxide absorbs moisture and becomes a poor conductor, its electrical conductivity decreases.
(1) All the genotypes are as follows: AABB, AaBB, AABb, AaBb, aaBB, aaBb, AAbb, Aabb, aabb.
(2) Assuming that Aa is dominant and Bb is recessive, there will be 9 phenotypes with both A and B allele dominant (i.e. AaBb, AABb); there will be 3 phenotypes with just the A allele dominant (i.e. Aabb, AAbb); there will be 3 phenotypes with just the B allele dominant (i.e. aaBb, aaBB); and there will be 1 phenotype with both alleles recessive (i.e. aabb). The phenotypic ratio in this case is 9:3:3:1.
(3) The probability of producing an offspring with the aabb genotype is 1/16 or 6%.
