Answer: 25 of the chicks will be black
Explanation: Since the chickens are intermediate in colour, that is they are not black, they are heterozygous. Let B represent the allele for black colour and B represent the allele for blue colour, therefore the genotype of a chicken with an intermediate colour is Bb. A cross between two Bb chicken will produce 1 BB, 2 Bb and 1 bb chicks. 1 BB will manifest outwardly as black, 2Bb will manifest outwardly as intermediate colored while 1 bb will manifest outwardly as blue colored chicks.
Since one out of four chicks are black colored, if the two chicken produced 100 chicks, the number of chicks that will be black is 1/4 x 100 = 25. Therefore, 25 chicks out of 100 will be black.

Answer:
A
Explanation:
The thrifty gene hypothesis postulates that due to dietary scarcity during human evolution, people are prone to obesity by storing energy as fat, an ability to take advantage of rare periods of abundance and this is advantageous during times of food availability. individuals with greater adipose reserves would more likely survive famine. This tendency to store fat could lead to obesity.
FTO is an enzyme that is encoded in humans by FTO gene located on chromosome 16. Increase in this enzyme is associated with the regulation of energy intake but not feeding reward. Also, the set point theory indicates that bodies are meant to stay within a narrow weight range but it is susceptible to chnage overtime.
Complete question:
You hang a swing from a live tree branch that is roughly parallel to the ground. What will likely happen over time as the tree grows? Check All That Apply
- The swing will move farther away from the tree trunk.
- The swing will move up. away from the ground.
- The swing will remain in its original position.
- The swing's ropes will become embedded in the branch.
Answer:
The swing's ropes will become embedded in the branch.
Explanation:
The trunk or branch strangulation sadly occurs very often. When people tie a young tree with different materials, such as a rope, or a cable, or a wire, and leave it there, the leash will eventually strangulate the tree.
Strangulation occurs because the tree keeps growing, applying pressure on the leash. The vascular system is in the trunk perimeter under the crust. Through the years, the pressure increases, the trunk is even more strangulated, and the vascular system is affected. One of the first and principal effects of strangulation is the increase in the trunk or branch diameter over the leash. This diameter change is because elements of the sap can not go back to the roots and keep near the strangulation. At this point, there are two options:
- The tree can sort this by including the leash in its tissues, surrounding and absorbing it, and keep growing normally
or
- The vascular system is so affected that the tree can not sort this problem and so, those parts of the tree located over the leash dye.
<em>In the exposed example, it seems that the tree could make it and included the swing's ropes in the branch. </em>
Answer: The Principle of Original Horizontality
Explanation: The Principle of Original Horizontality states that layers of sediment are at first deposited horizontally below the movement of gravity. It is a relative relationship technique. The precept is critical to the evaluation of folded and tilted strata.
