Answer:
Option C
Explanation:
Let the allele for long fin trait be "L" and the allele for short fin trait be "l"
Given L is dominant over l
If he crosses a long fish and short fin to produce three fourth long fins and one fourth short fins, it is not confirmed that the long fin species are homozygous as represented in the cross below
Ll * Ll
LL, Ll. Ll, ll
The two parent species are long (but not homozygous). Hence, option A is incorrect
However, if this test cross is carried out several times, the recessive trait may disappear thereby producing only homozygous long finned species.
Hence, option C is correct
Answer:
High mountains
Explanation:
Because they are high up in the air
That's because it helps migrate the serves in 2 important purposes: conserve (save) energy and it is easy to keep track for the birds to fly in the group.

Answer:
b. The number of each type of atom is the same for both the reactants and products.
Explanation:
A balanced chemical equation is characterized by each of the atoms of the reactants and the products being equal to each other. The atoms present in the reactants are also present in the products but are just rearranged. The equal number of atoms from both sides of the equation (reactants and products) follow the Law of Conservation of Mass.
Answer:
The mass number is the sum of protons and neutrons. This means to find the number of neutrons you subtract the number of protons from the mass number. On the periodic table, the atomic number is the number of protons, and the atomic mass is the mass number.
