Answer:

I don't exactly know too much about fossils and current animals, so I'll try my best.

Explanation:

Fossils provide evidence about life on Earth that currently extinct. Through fossils, we've discovered several species of animals and plants that previously existed. We also learn how life on Earth changed throughout the years. Fossils found in younger rocks look like animals and plants that are living today. Fossils in older rocks look less like the current living animals and plants. Some fossils found look either more or less like current species we know today.

Considering the body’s organization from atoms to organ systems, in which level of organization are proteins like collagen? Desc
storchak [24]

Answer:

According to the levels of organization in the body, the level of organization in which proteins, like collagen, are found is the molecular level, allowing the structural support and the performance of other essential functions.

Explanation:

Proteins are biological macromolecules, polymers of units called amino acids. These molecules belong to the molecular level of organization in living organisms.

The level of organization where proteins are found allows them:

  • <em>Form an essential part of cells.</em>
  • <em>Contribute to the construction of tissues and organs.</em>
  • <em>Participate in metabolic reactions, as enzymes. </em>
  • <em>Defense of the organism, in the form of antibodies.</em>
  • <em>Regulation of vital functions, forming hormones.</em>

Other functions of proteins are to integrate the cell membranes and perform transport function, to form receptors and to be an energy reserve.

does a cross bridge in a sarcomere of a fast fiber produce the same amount of forces as a cross bridge in a sarcomere of a slow
Zolol [24]

Answer:

Cross bridge in a sarcomere of a fast fiber produce higher amounts of force as compared to a cross bridge in a sarcomere of a slow fiber

Explanation:

When a muscle contracts, a cross bridge is formed between actin and myosin. The sarcomere shortens when a muscle contracts by reforming cross bridge. In general a muscle fiber is of three types – a) slow, b) Fast and c) intermediate.  

The sarcomere of fast fiber generates high force but for a short period of time. On the other hand, sarcomere of slow fiber generate lower amounts of force but this force lasts for a longer period of time. Due to this difference, fast fibers are the predominant fibers in the body
