An organic molecule will always contain _____.

1 answer:

5 0

The subject area of Chemistry is a very broad area. So, it is classified into sub-branches like inorganic chemistry, organic chemistry, physical chemistry, quantitative chemistry and many more. But when the basis is on the composition of elements, it is divided into inorganic and organic chemistry. Compounds containing the element Carbon are all under organic chemistry. If they do not contain carbon, they are considered as inorganic.

During the early times, the only differentiation between these two sub branches is the vital theory. This theory proposes that all things that have life can be only made by nature alone are inorganic. But thing was disproved by Wohler when he was able to synthesize urea from inorganic compounds. Thus, today the only differentiation is the carbon atom.

Explanation:

The cerebral cortex of the brain has four paired lobes.
one of these four paired lobes is the frontal lobe and it occupies 2/3rds of the entire human brain.
the frontal lobe is associated with performing tasks such as speech and language production, walking and running, classifying and identifying objects, reacting to feelings, forming memories, forming the personality of a person, and attention involving tasks.
Since after the injury, Zack has an altered personality and his reaction to the situation has changed, this points out to the fact that he is most likely suffering from frontal lobe injury.

members of the gram-negative genera aquifex and hydrogenobacter are hydrogen-oxidizing bacteria. an example of their metabolism

melomori [17]

Hydrogen-oxidizing bacteria are the members of gram-negative bacteria, metabolism involves using hydrogen as an electron source and oxygen as a terminal electron acceptor, hence forming water.

Gram-negative genera Aquifex and hydrogenobacter stand for "water-maker" to indicate hydrogen oxidation and terminal electron transfer to oxygen. They are chemoautotrophs, that share the ability to oxidize H₂ and fix CO₂ to provide energy and synthesize cellular material. Applicatated for resource recovery and pollution removal.

They are known to grow at the highest temperature and grow usually at neutral or slightly acidic pH. These microorganisms use CO₂ assimilation pathways. They are metabolically versatile chemolithoautotrophs, using reductive tricarboxylic acid (rTCA) cycle.
