In a flock of birds, parents can raise small clutches on their own but can increase their clutch size if they have a helper. You want to see if altruistic behavior is likely to spread. To do this you observed a male bird that stayed at his birth nest for a year to help raise the offspring of his father and his stepmother (the original mother died) and then built his own nest the following year. You calculated direct fitness (cost) for the male bird by counting the number of offspring he produced in one year and multiplied it by ½ due to the relatedness between parents and offspring. To calculate his indirect fitness (benefit), you took the total number of offspring produced in his birth nest by his father and stepmother when he assisted them and multiplied it by ½. To determine if this altruistic behavior would spread you subtracted the cost from the benefit to determine whether it was greater than 1. What did you do wrong
Answers
Answer:
The mistakes made
Altruistic behavior is measured as ; b - c > 0 and not b - c > 1 relatedness for half siblings = 0.25 and not 1/2Explanation:
The relatedness between ; Mother, father, daughter and son = 0.5 ( 1/2 ) which is included in the direct fitness category ( For the MALE bird )
The relatedness for the Half brother and Half sister of the male bird = 0.25 ( 1/4 ) ( indirect fitness )
hence applying Hamilton's rule
Relatedness = rb - c > 0
where b = benefit , c = cost
∴Total fitness = ∑ direct fitness + ∑ indirect fitness
= 0.5x + 0.25y
hence the mistakes made

g Sickle-cell anemia arises from a mutation in the gene for the beta chain of human hemoglobin. The change from a GAG to a GTG in the mutant eliminates a cleavage site for the restriction enzyme MstII, which recognizes the target sequence CCTGAGG. These findings form the basis of a diagnostic test for
Answers
Answer:
The sickle-cell gene.
Explanation:
The sickle cell mutation is in the gene encoding the β subunit. The sickle cell gene is located on the short arm (p) of chromosome 11, at position 15.5. Sickle cell anemia is a genopathy caused by a single mutation that results in the substitution of an amino acid in the β chains of the tetrameric protein hemoglobin. It characterized by the presence of sickle cells in the bloodstream, which are red cells or sickle-shaped erythrocytes. This form causes difficulty in the circulation of red blood cells. Confirmation of sickle cell anemia is obtained through tests that determine the presence and relative amount of hemoglobin S in a blood sample, that is, by checking the phenomenon of sickle cell disease, in a drop of blood between the slide and covers objects, or the presence of hemoglobin S by means of electrophoresis.

Hope this helps!
Measure the volume of a balloon filled with room temperature air; place the balloon in a freezer for an hour and measure its volume again would best investigate the effect temperature has on the volume of a gas. So, the correct option is C.
How volume effect the temperature of the gas?The ideal gas law states that the temperature of a gas is directly proportional to its volume. Specifically, the temperature of a gas will increase if its volume is decreased while its volume and pressure remain unchanged. If the volume of a gas is increased, its temperature will fall but its volume and pressure will remain unchanged.
This relationship can be explained by the fact that when a gas is compressed (that is, its volume decreases), the molecules are confined to a smaller area and move more away from each other and the walls of the container. Bars collide. Due to the increasing frequency of impacts, there is also an increase in kinetic energy, which increases the temperature.
So, the correct option is C.
