natali 33 [55]

The explanations of natural phenomena, and additional hypothesis most often come about as a result of a scientific theory.

Explanation:

Scientific theory is a general explanation of natural phenomena developed through extensive and reproducible observations, more general and reliable than a hypothesis.

Answers:

1. Facilitated diffusion: the process by which some molecules that are not able to pass directly through a cell membrane are able to enter the cell with the aid of transport proteins.

2. Osmosis: the diffusion of water molecules through a selectively permeable membrane.

3. Diffusion: the spreading out of molecules across a cell membrane until to they are equally concentrated.

Step-by-step explanation:

Diffusion is the spontaneous movement of molecules across a membrane from an area of high concentration to one of low concentration gradient.

Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of low solute concentration to one of high solute concentration.

Facilitated transport occurs when molecules cannot diffuse directly through a cell membrane but can diffuse down a concentration gradient through transport channels in the membrane.

Trichodesmium is a nitrogen-fixing cyanobacteria. Why might this cyanobacteria be important to other organisms in nitrogen-poor
eimsori [14]
Cyanobacteria don't need oxygen to survive they produce oxygen. They where the first ever known organisms on the planet and they produced oxygen in the oceans which was absorbed by iron deposits and then once the iron had oxygen the ocean got the oxygen until it got into the atmosphere and Eukaryota bacteria evolved. So the answer would be: <span>They convert nitrates from the water into nitrogen gas (N2) that is released into the atmosphere.</span>

Explanation:

A two are eukaryotes, and four are prokaryotes. This answer is wrong because animalia, plantae, fungi and protista are eukaryotes.

B four are plants, and two are animals. This answer is wrong because only one kingdom is plants (plantae).

C two are prokaryotes, and four are eukaryotes. This answer is right there are two prokaryotes (eubacteria and archaebacteria) and the others are eukaryotes.

D four are bacteria, and two are eukarya. This answer is wrong there are only 2 bacteria not 4.
