Answer:
A
Explanation:
There are different mechanisms for transport of molecules across the cell membrane. One kind of this transport is facilitated diffusion, this is a form of passive transport, not requiring any ATP (the opposite would be active transport, where it does require ATP.
Simple diffusion does require special transport proteins, and neither does osmosis. Filtration is a technique used for sterilisation of water, where any impurities can be drawn out of the liquid
The correct answer is: Events that occur early in the fossil record are represented by branching events nearer to the root of a phylogenetic tree.
Fossil records explain the history and evolution of life based on fossils. Fossils are remains of organisms preserved in sedimentary rock. In fossil records they are analyzed and arranged chronologically and in taxonomic order, so that can represent the evolution.
Phylogenies describes the relationships between organisms (species): from which organisms it is evolved, to which species it is most closely related etc. and it is represented as a diagram or phylogenetic tree. It is used to organize living organisms into specific categories. Characteristics of fossils are used to generate a phylogenetic tree, more precisely their roots that represent common ancestors.
Answer:
Ов. H,0
Explanation:
Hydrogen is present in our body about 9.5 percent while oxygen is present in large amount about 65 percent of the total human body. Oxygen mostly present with hydrogen in the form of water. About 70 percent of our body is composed of water. Water is present in every cell. Some oxygen is also present in gaseous form in the cell. This oxygen comes in the body through breathing.
The dependent variable is the part of the experiment that depends on the other part, the independent part. The dependent variable would be the plant because it's growth depends on the light wavelength.
