Long legs (L) in racing horses is dominant to short legs (l). Good muscle tone (G) is dominant to weak muscle tone (g). Determine the phenotypes of the F1 generation resulting from a cross between a heterozygous long legged, weak muscled horse and a heterozygous long legged, strong horse
Answers
Answer:
See the answer below
Explanation:
Long leg (L) is dominant over short leg (l) and Good muscles (G) is dominant over weak muscles (g).
Heterozygous long leg, weak muscle = Llgg
Heterozygous long leg, strong muscle = LlGg
Llgg x LlGg
Offspring:
2 LLGg - Long leg, strong muscle
4 LlGg - Long leg, strong muscle
2 LLgg - Long leg, weak muscle
4 Llgg - long leg, weak muscle
2 llGg - short leg, strong muscle
2 llgg - short leg, weak muscle
Ratio of offspring with long leg and strong muscle = 6/16 or 3/8
Ratio of offspring with long leg and weak muscle = 6/16 or 3/8
Ratio of offspring with short leg and strong muscle = 2/16 or 1/8
Ratio of offspring with short leg and weak muscle = 2/16 or 1/8

Atoms of carbon-14 are radioactive. They decay into atoms of the element nitrogen. Suppose that a sample of rock is taken from a fossil. The sample has 500 atoms of carbon-14 and 1500 atoms of nitrogen. If carbon-14 has a half-life of 5700 years, how old is the fossil? 5700 years old 11,400 years old 17,100 years old 2850 years old
Answers
Answer:
11,400 years old
Explanation:
The total number of atoms present at the beginning = number of C-14 + number of N-14 atoms.
Hence;
1500 + 500 = 2000 atoms = No
At time t, N = 500 atoms of C-14 remains
Since the half life of C-14 (t1/2) = 5700 years
N/No = (1/2)^t/t1/2
500/2000 = (1/2)^t/5700
1/4 = (1/2)^t/5700
(1/2)^2 =(1/2)^t/5700
2 = t/5700
t = 2 * 5700
t = 11,400 years old

C. Each parent has two copies of each gene and passes on only one copy to its offspring.
D. Each parent has one copy of each gene. each offspring receives half of its genes from each parent.
Answers

Answers
Answer:

Glucose can pass through the semi permeable membranes where the molecules can pass because they are soluble in water enough. The molecules can pass through because of the solubility factors.
What is a semi permeable membrane ?It is the semi permeable membrane where the half of the molecules get passed through the membrane. The molecules are selectively present.
Cell membranes are an example of semi-permeable membranes. Cell membranes allow small molecules such as oxygen, water carbon dioxide and glucose to pass through, but do not allow larger molecules like sucrose, proteins and starch to enter the cell directly.
Transport is helped by certain molecules as well where the few of the ions, channels and the molecules are taken up by the membrane through the selected transportation of the ions.
