Answer: There are two ways to determine the age of a dinosaur fossil. One is called relative geologic time, which involves deciding whether one dinosaur fossil is older or younger than another. Geologists then measure the proportion of parent and daughter atoms present in the ash crystals to determine the crystal's age.

Explanation:
<em>Hemophilia typically affects more males than females because the disorder is </em><em>X-linked </em><em>and </em><em>recessive</em><em>. </em>
<u>Females have two X chromosomes (XX) while males only have one X and one Y chromosome (XY). The two X chromosomes in females are capable of carrying alleles while the Y chromosome in males is hypothesized not able to carry alleles. </u>
Consequently, the two X chromosomes in females will both need to carry the recessive allele of hemophilia in order for any female to be affected for hemophilia while the males only need their single X chromosome to carry the recessive allele in order to be affected.
In order words, the presence of a single recessive allele is not enough for a female to be affected while it is more than enough for a male to be affected. Hence, more males are affected b hemophilia disorder than females.

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
