Answer: Cells.

Explanation:

A tissue is a group of cells that have a similar structure and work together to have the same function. These groups of cells make up organs such as lungs, heart, skin or brain.<u> So it is an organisational level between cells and a complete organ</u> because it ensembles similar cells and their extracellular matrix. To fully understand this, we have to consider that a cell is the smallest structural and functional unit of all organisms. So when they are aggregated together, they form tissues.

The release of an inorganic phosphate from the myosin molecule directly results in ________
zhuklara [117]

Answer:

power stroke

Explanation:

  • The process of muscle contraction requires several steps.
  • The most famous theory on how the contraction and relaxation of muscles take place is the sliding filament theory.
  • However, this theory has been refined and one important addition to it is the mechanism by which myosin can pull actin and cause shortening of the sarcomere.
  • For the movement of myosin, it binds and releases actin and forms cross bridges.
  • Myosin is subdivided into two regions - S1 and S2. The contraction of the S1 region is what constitutes the power stroke.
  • An important requirement of the power stroke is the hydrolysis of ATP to release an inorganic phosphate which provides energy for the process.

Fofino [41]

Answer:

a. A hypothesis that does not generate a testable prediction is not useful.

Explanation:

In the scientific method, we generate a hypothesis to explain a phenomenon. After this, it is necessary to create a method to test the hypothesis and make predictions. Moving forward, we test this methodology, generating results and reject or not reject the hypothesis. If the hypothesis can't be tested, the scientific method can't be applied.
