B. Single-celled eukaryotes that sometimes grew in colonies
C. Multi-cellular organisms that were probably autotrophic.
D. Multi-cellular organisms with an alternation of generations lifecycle.
The correct answer is B. Single-celled prokaryotes that sometimes grew in colonies
Answer:
The probability of having offspring that have wrinkled seeds and yellow seed color for the cross RRYY ´ RrYy is zero
Explanation:
Given
Round see (R) is dominant to wrinkled seed (r)
While Yellow seed (Y) is dominant to green seed (y)
Now a cross is carried out between RRYY * RrYy, the following offspring are produced
RRYY * RrYy
The gametes of RRYY are RY, RY, RY, RY
The gametes of RrYy are RY, Ry, rY, ry
RY Ry rY ry
RY RRYY RRYy RrYY RrYy
RY RRYY RRYy RrYY RrYy
RY RRYY RRYy RrYY RrYy
RY RRYY RRYy RrYY RrYy
Genotype Ratio
RRYY: RRYy: RrYY: RrYy
4:4:4:4
1:1:1:1
Phenotype
All are round and yellow
The probability of having offspring that have wrinkled seeds and yellow seed color for the cross RRYY ´ RrYy is zero
Answer: B) Limited
Explanation:
Especially in drier regions, water is a limited resource.
a. the products have been rearranged to form reactants
b. AC is a reactant
c. CD is a product
d. the products have less potential energy than the reactants
e. entropy has decreased
Answer:
d. the products have less potential energy than the reactants
Explanation:
AB + CD → AC + DB
Reactants → Products
AC is a product not a reactant
DC is a reactant not a product
Entropy always increases in products
The products have not been rearranged to form reactants
In this reaction d. the products have less potential energy than the reactants
The potential energy of a molecule is the energy stored in the bonds between the atoms in the molecule. When two molecules react, the bonds in the reactants are broken and new bonds are formed in the products. If the bonds in the products are stronger than the bonds in the reactants, then the potential energy of the products will be lower than the potential energy of the reactants.
In this reaction, the potential energy of molecules AB and CD is higher than the potential energy of molecules AC and BD. This means that the bonds in the products are stronger than the bonds in the reactants.
