The average speed of the zebra during time between 0s and 40s is 34 seconds.
The average speed, a scalar value which is greater than or equal to the magnitude of the average velocity of a substance.
In general speed = distance / time
it is calculated by dividing the total distance travelled by the
total time taken for the substance to reach the destination.
If the average speed is zero which is equivalent to average velocity.
If the direction of the path has been changed then the average speed will be greater than the magnitude of the average velocity

Answer:
disruptive/diversifying selection
Explanation:
Disruptive (also known as diversifying) selection is a type of natural selection where extreme phenotypic values are more favored rather than intermediate phenotypes. The disruptive selection favors the survivance and reproduction of organisms with extreme phenotypic traits, and in turn impairs the reproduction of organisms with intermediate traits, thereby changing the allele frequencies in the population in order to favor extreme values. An example of disruptive selection is the beak size of Galapagos finches, where extreme phenotypes of this trait have shown to be adaptive according to the type of food found in each island.
Answer:
fibrin
Explanation:
Fibrin is a protein that acts as a first response whenever your body is injured in order to play an important role in the blood clotting process. When any type of injury that causes blood leakage occurs and coagulation begins, an alert is then sent to the body to start producing fibrin.
In the form of long strands, each fibrin molecule intertwines to form a thin mesh around the lesion. As a result, this mesh stops the blood by capturing red blood cells, leukocytes and platelets, generating a clot and forming a kind of tampon at the injured site.
In summary, we can say that fibrin is a yarn-like protein that binds to platelets in blood clotting.
B. Thiamine pyrophosphate
C. Biotin
D. FAD
Answer: Option B.
Thiamine pyrophosphate.
Explanation:
Pyruvate dehydrogenase is an enzyme that catalyses the oxidative decarboxylation of pyruvate to acetyl coA , NADH and CO2. Pyruvate dehydrogenase uses NAD, biotin, FAD and lipoic acid.
Thiamine pyrophosphate is not a cofactor for pyruvate dehydrogenase . It is a cofactor in living systems. Thiamine pyrophosphate is a coenzyme that function in carbohydrates, Amino acids and lipids metabolism.
Biotin is not a cofactor in the reaction catalyzed by pyruvate dehydrogenase. NAD+, Thiamine pyrophosphate, and FAD do function as cofactors in this reaction.
The cofactors used in the reaction catalyzed by pyruvate dehydrogenase are NAD+, Thiamine pyrophosphate, and FAD. The compound that is not used as a cofactor in this reaction is Biotin. Biotin functions as a cofactor for carboxylase enzymes, and it is involved in fatty acid synthesis and gluconeogenesis but not in the process involving pyruvate dehydrogenase.
