Answer:

electrons/ions

Explanation:

The electric current is produced by flow of any charged particle. These charged particle can be electron, ion etc. The current produced by flow of electron is also called as electron current. The electrons/ions flow from a region of high concentration of “negative charges” to a region of low concentration of “negative charges” . This movement of electron takes place across a wire.

2. How has genetics, combined with paleontology, added to our understanding of evolution?

motikmotik

Answer:

To find the extinct species and their divergence of characters can be studied using molecular genetic techniques.

Explanation:

Paleontology is the study of ancient species and their remaining that were found millions of years ago. These species extinction can be found and manipulated to find out the origin or divergence of species from their origin
The samples of these species may contains their remains that help the biologist to isolate and analyze their protein or DNA. when the DNA is isolated their sequences can be generated using molecular biology techniques.
When the sequences are identified by advanced molecular biology techniques, the existence and similarities of different species due to their convergence or divergence can be identified.
By identifying the convergence or divergence the characteristics, evolutionary change in behavior, variation in appearance can be studied.
By using these techniques, biologist have found that homo sapiens are 99% have their similarities with chimpanzee
Thus, using genetics in paleontology helps us to understand adaptation a species is changing according to the evolutionary changes.

Different microbes grow in a wide variety of environmental conditions; however, most have preferences for certain temperatures,

lesya692 [45]

Answer:

this is a TRUE statement.

Explanation:

Different microbes grow in a wide variety of environmental conditions; however, most have preferences for certain temperatures, pH, and atmospheric gases because although microbes are widespread in their occurrence,they are found almost everywhere,in the air,water,soil,food,decaying matter,oil deposits,in plants etc.

but their number and their types vary according to the locality and environmental conditions.

Although, some microbes are always present and contribute towards natural flora BUT besides this others are present in specific environments such as some in hot springs bearing very HIGH TEMPERATURE RANGES for example: Thermus aquaticus.

some of them inhabit the acidic or alkaline soil feeding on HUMUS.

Most of the microbes prefer ATMOSPHERIC GASES i.e some require oxygen for their survival .For example: Pseudomonas.

some don't require O2 for survival i.e Spirochete.

IN SHORT, most of the microbes have preferences for various environmental conditions.
