Answer:
Frequency of dominant allele is 0.9029
Explanation:
Total number of organisms = 12,845
Number of organisms representing dominant trait = 11,596. These organisms might have heterozygotes with one dominant allele and one recessive allele.
Hence, Number of organisms with recessive alleles = 12845 – 11596 = 1249
Frequency of recessive allele (q) = 1249/12845 = 0.0971
Frequency of dominant allele (p) = 1- q = 1- 0.0971 = 0.9029
Answer:
Humans cannot occupy the lowest levels.

Answer:
Option C
Explanation:
Please see the image attached
In this image we can see that the Primate A is waking through the tree by using all its four limbs i.e rear and front limbs. Such primates have Arboreal quadrupedalism. Their hand and feet bend towards the direction of the curve of the support. They have long lever arms which provide gear ratio for grasping and greater leaping distance. However, their feet are also able to grasp.
Option C is correct
Answer:
t= 3886.18 years old
Explanation:
Whenever an animal dies de C14 and N14 begin to disintegrate in such a way that the proportion between C14 and C12 decreases, with a semi-disintegration period of 5.730 years, T. To get to know how long it takes an element to disintegrate, we must use this semi-disintegration period, which is the time it takes until the amount of the element is reduced to its half.
We can find the age of the fossil, t, by using the next formula:
t = - (T x ln (C14))/ ln (2)
t = - (5730 x ln (0.625)/0.693
t= - (-2693.12)/0.693
t= 3886.18
