<h2>e) option is correct </h2>
Explanation:
- Cap Z is a capping protein which controls the access to the free barbed ends of actin filaments and is therefore a major factor affecting actin filament elongation
- Capping proteins have a high affinity for barbed ends and their micromolar concentration in the cytoplasm ensures that most barbed ends are capped
- Depletion of capping protein promotes increased filament assembly away from the leading edge in migrating cells
- Cap Z helps favor actin assembly by preventing the loss of actin subunits to the barbed end and also prevent annealing of severed or de-branched filaments and they block both the association and dissociation of subunits at the barbed end
Complex organic food molecules such as sugars, fats, and proteins are rich sources of energy for cells because much of the energy used to form these molecules is literally stored within the chemical bonds that hold them together. Scientists can measure the amount of energy stored in foods using a device called a bomb calorimeter. With this technique, food is placed inside the calorimeter and heated until it burns. The excess heat released by the reaction is directly proportional to the amount of energy contained in the food.

Answer:
Ok, so what electronegativity means is it measures the tendency of an atom to attract a shared pair of electrons. It is modified by both its atomic number and the distance at which its valence electrons equivalent from the charged nucleus.
