Thick myosin filaments of muscle are associated with the characteristics of contractility.
Explanation:
The muscle contractility is provided mainly the thick and the thin muscle filaments. Thick muscle filaments are constituted by the contractile protein, myosin. Thin filament is composed of actin.
Owing to its thickness, myosin protein is made up of six chains of polypeptides with four lighter (molecular mass is low) ones and two heavier (molecular mass is high) ones.
The two heavier polypeptide chains twist together like two twisted golf clubs and forms a coiled-rod like structure. This coiled structure looks like a two stranded double helix.
The globular heads point out from the main body in each coiled structure and adheres with the head of the actin filaments. The tails made up of lighter chains point towards the M lines of the sarcomere.
During muscle contraction, the myosin head will attach with its myosin-binding site.

The rapid change in the climate would potentially lead to ecological problems because evolution is unlikely to occur quickly enough to keep pace with biome changes.
<h3>What do you mean by Evolution?</h3>
Evolution may be defined as the process of growth and development or the theory that organisms have evolved and developed from past organisms.
Biome changes occur due to the fact of evolution. Both evolution and biome changes synergistically move forward to support organisms' life in a much better way.
Therefore, the rapid change in the climate would potentially lead to ecological problems because evolution is unlikely to occur quickly enough to keep pace with biome changes.

Answer:
Rate of photosynthesis will be increased
Explanation:
Photosynthesis is a process whereby plants manufacture their food (in form of carbohydrates) in the presence of sunlight. The photosynthetic process, which occurs in the chloroplast of plant cells, require carbon dioxide (CO2) as one of the reactants, from the atmosphere. The general photosynthetic equation is given below:
6CO2 + 6H2O → C6H12O6 + 6O2
Based on the above equation, it shows that carbon dioxide (CO2) as a reactant can either increase or decrease the rate at which photosynthesis in plants occur depending on whether it is increased or decreased in the atmosphere respectively.
According to this question, the concentration of carbon dioxide in the atmosphere has been increasing for many years. This means that the rate at which photosynthesis by plants occur will also be INCREASED.
“Factors Affecting Enzyme Activity. ... Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.” I hope this helps you
