Misha Larkins [42]3 years ago
5 0

In simple diffusion, small molecules without charges such as oxygen and carbon dioxide flow through a plasma membrane without assistance and without expending energy. Other substances such as proteins, glucose and charged particles called ions cannot pass through the selectively permeable membrane.

How does the body of a 100m sprinter produce energy for this event?
mafiozo [28]
Its estimated that during sprint events approximately 95% of energy production comes via the anaerobic system (85% phosphate, 10% anaerobic glycolysis), and only 5% from aerobic oxygen. Thus, the 100m sprint is an anaerobic event relying heavily on energy supply from the ATP-PC system!

What are your 3 best evidences for evolution?
Semmy [17]

Answer:

Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).

Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.

Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.

Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.

Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).
