The human body reserves creatinine phosphate as the energy source at the start of 100 yard dash (race).
The creatinine phosphate is converted into ATP, which is the energy package of our body. ATP is body's usable form of energy. Energy is stored in various forms in our body such as fats, carbohydrates and proteins. At a microscopic level, it is stored in molecules like creatinine phosphate. Carbohydrate and fats are the primary source of our body followed by proteins.
Our body uses three different forms of metabolism to convert these molecules in ATPs. These three processes are Phosphagen System, Aerobic Respiration and Glycolic/Anaerobic respiration.

When sound waves hit a solid surface they either reflect, refract, or absorb.
Echo's are caused by the reflection of sound waves.
Asbestos fiber accumulate in the <em>lysosomes.
</em>
Option: (b)
<u>Explanation:
</u>
Asbestos is a natural group of minerals and it is composed of thin and needle-like fibers. An asbestos causes several diseases like cancers and so on, including asbestosis and mesothelioma.
Although asbestos extend and fireproofs materials, this materials are banned in ‘many countries’. But asbestos are not banned in the United States.
Lysosomes are important part of the ‘endomembrane system’ because lysosomes are formed from the ‘endoplasmic reticulum’ and these products are synthesized and processed by the ‘Golgi’.
Answer:
The neutrophil forms multiple lamellipodia extensions
Explanation:
Neutrophils are white blood cells (granulocytes) which comprise the first line of defense in the innate immune system. The lamellipodium (in plural, lamellipodia) is a cytoskeletal actin extension found in mobile cells, whose main functions are cell motility and migration. Rac1 is a member of the Rho GTPase protein family which is involved in actin-myosin cytoskeletal reorganization of neutrophil cells in response to microorganism infections. In this regard, it has been shown that Rac1 controls the initial uncapping of actin ends in order to regulate cytoskeleton dynamics, thus regulating lamellipodia formation. By using mice as models, researchers observed that Rac1 constitutive activation may lead to the formation of multiple lamellipodia in neutrophils.
