Answer:
Myosin
Explanation:
Myosin are the major components of both muscle and non muscle cells in striated muscles which is responsible for contraction or movement that convert chemical energy (ATP) into mechanical work thereby generating force and movement.
During cellular movement , myosin filament will be the ones that are responsible for attaching and pulling the other filaments along because Myosin binds to actin at a binding site on the globular actin protein,it also have ATP binding sites which hydrolyses ADP to ATP , ATP binding causes myosin to release actin, which make actin and myosin to detach from each other thereby causing attachment and contraction of other filaments
Answer:
b. Red cars are more difficult to view in the evening and are therefore more prone to accidents in medium-light conditions
Explanation:
Red colored cars are more dangerous than other colored cars because red color cars can not be seen in the evening or dark environment so that's why more accidents were observed with red color cars as compared to another color cars. Red is a vibrant color and one of the most dangerous cars colors. People sometimes confused with traffic lights, brake lights etc and accident happen.
<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
Let us consider a drop of water in a river. The droplet flows to a larger body of water such as a lake. From here, or even from the river, the droplet changes from the liquid to the vapor phase via the process of evaporation and goes into the atmosphere. In the atmosphere, the droplet is condensed back into the liquid phase in the form of cloud. When a sufficient amount of water has been created in the clouds, it precipitates back on to the ground and flows into rivers and streams again.<span />
Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
