Answer:
75% brown, 25% white
Explanation:
This question involves a single gene coding for color in chickens. The allele for brown color (B) is dominant over the allele for white color (b).
According to this question, a brown rooter with genotype 'BB' was crossed with a white hen (bb). The offsprings in the F1 generation will all possess the 'Bb' genotype and be brown colored. However, if these F1 offsprings are self-mated i.e Bb × Bb, the proportion of F2 offsprings will be 1BB, 2Bb, 1bb.
Since BB, Bb and Bb offsprings are Brown in color and bb is white in color, this means that the expected phenotypic appearance of the F2 offsprings will be:
¾ or 75% brown and ¼ or 25% white

Potassium-40 has a half-life of 1.3 billion years. If a rock was
determined to be around 3.9 billion years old what percentage
of the original potassium-40 would be left in that rock sample?
Answer: The 3.9 billion year old rock has undergone three half-lives (3.9 divided by 1.3 = 3). After 3 half-lives, 12.5% of the potassium-40 remains undecayed.

A protein being built from individual amino acids would be an example of
A. Anabolism
B. Catabolism
C. Cell Division
Answer: A
Explanation:
Anabolism is the synthesis of a complex molecules from simplier ones. An example of this is the production of proteins from indiviudal amino acids.
Catabolism is the breakdown of complex molecules into simplier units. An example of this would be breaking down a protein into its individual amino acids.
Answer:
The breaking down of starch into its component sugars would be an example of
✔ catabolism

How do weathering and erosion work together to change or build landforms
Answer:
Erosion is another geological process that creates landforms. When mechanical and chemical weathering breaks up materials on the Earth's surface, erosion can move them to new locations. For example, wind, water or ice can create a valley by removing material. Plateaus can also be formed this way.

The advantage of being able to clone the gene for human insulin is that
A) using human insulin increases the probability that, in the future, the person suffering from diabetes can be weaned from a dependence on insulin.
B) human insulin is less likely to cause harmful side effects than cow, pig, or horse insulin.
C) cow, pig, or horse insulin cannot keep a diabetic alive for more than three months.
D) there are too few cows, pigs, and horses to provide an adequate supply of their insulin.
The advantage of being able to clone the gene for human insulin is that using human insulin increases the probability that, in the future, the person suffering from diabetes can be weaned from a dependence on insulin. Thus, option A is correct.
What is clone?The term clone has been defined as the exact copy of organism. The first clone is the dolly ship which has been created in the scientific manner. Human insulin is less likely to cause harmful side effects than cow, pig, or horse insulin.
There are too few cows, pigs, and horses to provide an adequate supply of their insulin and by using human insulin increases the probability that, in the future, the person suffering from diabetes can be weaned from a dependence on insulin.
Genetically engineered insulin is the synthetic human insulin which has been manufactured from the DNA sources in the laboratory. One advantage of the using genetically engineered insulin has been that it causes fewer allergic reactions as compared to animal insulin.
Therefore, option A is the correct answer.
