Answer:
Hemophilia
Explanation:
Hemophilia is a disorder in which the blood fails to clot normally because it lacks enough blood-clotting proteins resulting in excessive bleeding from injuries. Other symptoms include:
- Unexplained and excessive bleeding after surgery
- Large or deep bruises
- Pain or swelling in knees and joints
- Presence of blood in urine or stool
- Bleeding into the brain which could sometimes occur from slight knocks to the head
It is a genetic disorder in that it occurs due to a defect in the genes. The disorder is located in the X chromosome found in females. Diagnosis is through genetic testing.
Answer :3. similarities among vertebrate forelimbs suggest that they evolved from a common ancestor.
Explanation:
The study of differences and similarities in the anatomy of different species is comparative anatomy. It is based on the concept that
1.)Homologous structures which are present in different species, because they have a common decent and must have evolved divergently from a shared ancestor. Theses anatomic structures may not be used for the same purposes. For example the forelimb of fox and whale.
2. Some structures (Analogous)which are similar in different organisms must have evolved ,(acquired through natural selection) through convergent evolution in similar environment, and not inherited from a recent ancestor. These organisms usually use these structures for a common purpose. For example the streamline body shape of shark and porpoises, which though are used for a common purpose of swimming, were inherited from different ancestors.
. Example of comparative anatomy is the common bone structures in forelimbs of fox, whales, bats, and humans. These appendages is made up of the same basic parts; despite serving different functions.
Comparative anatomy helps scientists in classification of organisms based on their similar characteristics of their anatomical structures.

Answer;
C. 100 - 125 mg/dL
A person with prediabetes has a fasting blood glucose level of 100-125 mg/dL.
Explanation;
-A fasting blood sugar level below 100 milligrams per deciliter (mg/dL) — 5.6 millimoles per liter (mmol/L) — is considered normal.
-A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 7.0 mmol/L) is considered prediabetes. This result is sometimes called impaired fasting glucose. A fasting blood sugar level of 126 mg/dL (7.0 mmol/L) or higher indicates type 2 diabetes.
