Water
Soil
The sun
Atmospheric Gases
Temperature.
These are just a few of many, but all abiotic factors are not living. Hence A-Biotic
Biotic means living, so when you put the ''a'' prefix it means the opposite of living.
Answer:
O sal tem uma grande capacidade de absorver água do ambiente.
Explanation:
A passagem de oxigênio pelas guelras de um peixe é um exemplo de difusão porque a difusão ocorre quando a concentração de uma substância é maior em uma região e menor em outra região, de modo que as partículas se movem da região superior para a região inferior. A glicose entra na célula por meio do processo de transporte passivo facilitado porque passa por uma membrana semipermeável por uma proteína específica. O transporte iônico nas células nervosas é o exemplo do transporte ativo porque se move pelo uso da energia contra o gradiente.
O sal tem uma forte capacidade de absorver água do seu entorno, então quando a alface temperada com sal, o sal absorve a água presente no interior da alface, portanto a retirada da água é a retirada da água é a causa do murchamento.
Answer:
Fungus
Explanation:
Chitin is a fibrous substance consisting of polysaccharides and forming the major constituent in the exoskeleton of arthropods and the cell walls of fungi. This would point to it most likely being a fungal agent. Hope this helps!
Answer:
When the molecules are too large.
Explanation:
Facilitated diffusion refers to the passive transport of substances down the concentration gradient via specific transport proteins present in the membrane. The large, polar, charged substances and ions cannot pass through the small spaces present between hydrophobic tails of membrane phospholipids. The transport proteins transport these substances in energy independent manner.
Answer:Evidence for evolution comes from many different areas of biology:
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)
