Answer:

The skeletal muscle with the shorter sarcomere length would shorten faster under a very light load.

Explanation:

A sarcomere is the unit of contraction in a striated muscle. Types of striated muscles include cardiac muscles and skeletal muscles.

All striated muscles are connected to the skeleton and the characteristic sarcomeres are functional in creating force and contractility.

The length of muscle sarcomeres affects how much and how fast the muscle contracts. A muscle with a longer sarcomere length, though having greater force, has a shorter range of contraction when compared to a muscle fiber with shorter sarcomere length.

Sarcomeres, are associated with protein fibres; myosin and actin. Myosin binds to actin after a calcium influx. The calcium influx serves to expose the binding sites of actin, enabling both proteins to bind in a cross binding pattern.

it has said that bacteria set the stage for other life forms to evolve on earth. what do you think is meant by that statement
3241004551 [841]

The statement, <em>“Bacteria set the stage for other life forms to evolve on earth” </em>was made probably because Earth was populated exclusively by single-celled organisms (Archaea and Bacteria) at the time that it was oxygenated, and only one of these can perform photosynthesis that separates a water molecule and results in oxygen gas, which is called Cyanobacteria, which has a blue-green color that comes from chlorophyll. Today, Cyanobacteria can practically be found everywhere on Earth, possibly in the soil right outside your door, and still play a vital role in producing the oxygen that we breathe. Another reason could be, billions of years ago, single-celled creatures had the planet to themselves. Then, they established different ways for cells to share and communicate resources. These intricate and complex multicellular creatures were the very first animals, and they were totally a major success. Consequently, animal life evolved about 540 million years ago.

Digest excess or Worn-out cell parts, Food particles, and invading viruses or bacteria.
nataly862011 [7]

the answer could not be D because a Golgi Apparatus  is a tiny structure, or organelle, in a cell that "packages" nutrients for use inside the cell. The answer could not be c. because a nucleus  is a tiny structure, or organelle, in a cell that "packages" nutrients for use inside the cell. The answer could not be  Endoplasmic Reticulum because that is where proteins are transported from one part to the other. So the only answer left is Mitochondria, because the Mitochondriamain function is to produce ATP, the energy currency of the cell.
