Answer:
from the intermembrane space to the matrix
Explanation:
In the electron transport chain (ETC), electrons flow from one protein complex to another. However, as this electrons are transfered, protons (H+) is built up from the intermembrane space of the mitochondria to the mitochondrial matrix.
Hence, according to this question, a proton gradient is formed when hydrogen ions (H+) are moving from the intermembrane space to the matrix of the mitochondrial.
Answer: Option A) Clade
Explanation:
A clade refers to a group of animals or other organisms that have evolved from a common ancestor species. It could have taken several millions of years since the first ancestor lived.
Examples of clade include
- all the birds descended from a common ancestor specie
- all apes descended from a common ancestor specie.
Also, a clade is best identified using a phylogenetic tree.
The range of evidence in firearms-related cases can be as small as a piece of a bullet fragment which has rifling marks or as large as hundreds of bullets and cartridge cases and numerous firearms. Even from small samples, information can be developed to indicate the type of firearm used and possibly identify the actual firearm that was used.
Other firearms evidence that could be found at a shooting scene includes shotshell wads and shot pellets; these can indicate the gauge of the shotgun. Wads and pellets can be gathered and preserved in the same manner as bullets and cartridge cases.
By examining wadding materials, the examiner may be able to determine
- The gauge of the shotgun
- The manufacturer or marketer
- A range of possible shot sizes based on impressions in the shotshell wad
- individual characteristics (in some cases)
