Which class of organic compound is most likely to be used in anesthetics?
ether
ester
alkyl halide
carboxylic acid
Answer:
A.ether
Explanation:
i got it right on edg 2020 and they use ether in pokemon games to heal PP so that makes logical sense lol
The class of organic compounds that are used in anesthetics is:
A. Ether
It is a functional group consisting of C and O.
What are Anesthetics?Anesthetics are an assorted gathering of medications with especially unique synthetic designs, going from basic inorganic atoms like nitrous oxide to additional perplexing natural specialists.
Organic compound is one that contains a bond with a carbon particle. In ethers, the practical gathering that is available is C=O. Ether, as a fluid, discharges fumes that are breathed in. Another very powerful fluid sedative is propofol, controlled intravenously.
Thus, correct option is A.

vertebrate paleontology
paleobotany
these are the chocies
Answer:
The study of fossil mammals comes under vertebrate paleontology
(aka vertebrate paleontology)
Answer:
The study of fossil mammals comes under vertebrate paleontology.
Explanation:
Paleontology is the study of fossils which tries to explain the evolution of organisms, their environment and interactions with each other. The various sub divisions of paleontology are vertebrate paleontology, invertebrate paleontology , micropaleontology, paleobotany, palynology etc.
The study of vertebrate fossils, from primitive fishes to the immediate ancestors of modern mammals is known as vertebrate paleontology. Invertebrate paleontology deals with the study of invertebrate animal fossils, such as molluscs, echinoderms, arthropods and annelid worms. Paleobotany studies fossil plants which includes the study of fossil algae and fungi in addition to land plants. Micropaleontology is the study of microscopic fossil organisms, regardless of the group to which they belong.

Answer: 6
Explanation:
Mark brainliest plzzz if correct
In C₃H₅( NO₃ )₃ there are total six number of oxygen atoms are present and three atoms of carbon, 5 atoms of hydrogen and 3 atoms of nitrogen present.
What is oxygen ?The chemical element with the atomic number 8 and symbol O is called oxygen. It belongs to the periodic table's chalcogen group, is a very reactive nonmetal, and an oxidizing agent that easily produces oxides with most elements as well as other compounds.
Dioxygen is the name given to the colorless, odorless, and tasteless gas that is oxygen at standard pressure and temperature.
Chemical elements are substances that only contain one kind of atom, such as oxygen. Since oxygen has an atomic number of 8 and the official chemical symbol O, an oxygen atom has eight protons in its nucleus. At room temperature, oxygen is a gas that has no flavor, color, or odor.
Thus, In C₃H₅( NO₃ )₃ there are total six number of oxygen atoms are present.

Which is the first step that geologists must do to compare rock layers at distant locations?
find the absolute age of rocks at both locations
compare a layer at one location to layers at other locations
identify index fossils in one or more layers at one location
collect fossils from different locations to study the organisms’ lifestyles
Answer: Comparing rock layers in distant places can be a challenge for geologists since these layers may have different environmental factors that caused different transformations in them.
Therefore, when it is necessary to establish a comparison between layers of rocks in different ligands, geologists must establish steps to make an efficient comparison and have results consistent with reality. To do this, they must first compare a layer in one location with layers in other locations, assign relative age to a layer in one location, and identify index fossils in one or more layers in one location.

Answer:
True
Explanation:
I just took that last year, and got a100%
True, Plants don't have brains, but they still adapt to their environments.
What is adaptation?Adaptation is a process where they are changing their nature to suit the environment.
We have seen that plants do adaptation according to the environment, as in the summer season their leaves are hanging down but in the rainy season they show blossoms and green leaves. So, according to the environment for the survival and reproduction they adapt their body.
Hence, plants have no brains, but they still adapt.

By the IUPAC Naming Convention followed by every chemical standards, the structure from the question is named as 4,4-dimethyl heptane.
IUPAC Stands for International Union of Pure and Applied Chemistry.This organisation issued some standards for naming any chemical components that is followed world wide.
According to the IUPAC Standards:
First of all we have to identify the longest carbon chain which is an alkane group according to this question.As a result of 7 carbon linked with single bonds it will be named heptane.Now moving to the other parts:
[tex]-CH3[/tex] is termed as methyl
As the both the methyl group( [tex]-CH3[/tex] ) is linked with the fourth carbon the numbering is 4 for methyl.So,the IUPAC name of this compound in the image is 4,4-dimethyl heptane.

3) Effect on Litmus paper - Dip a blue litmus paper in soda
4) Electrolysis - Add two electrodes to soda and connect a battery.
Does Soda show acidic properties?Soda, specifically carbonated beverages like cola or soda pop, typically exhibits acidic properties. The acidity of soda is primarily due to the presence of carbonic acid (H₂CO₃), which forms when carbon dioxide gas (CO₂) dissolves in water.
When carbon dioxide is dissolved in water under high pressure, it forms carbonic acid through the following reaction:
CO₂ + H₂O ⇌ H₂CO₃

Which of the following terms best describes an atom which is chemically unreactive?
A static
B full

D invert
Option D is the correct alternative.
We have a chemically unreactive element.
We have to determine which term best describes this atom.
What is Reactivity ?Reactivity in chemistry is the impulse for which a chemical substance undergoes a chemical reaction, either by itself or with other materials.
According to the question -
An atom that that does not react with the other atoms belongs to those elements which are chemically unreactive or inert elements. The reason behind their inertness is their completely filled outermost shell which can accommodate a maximum of 8 electrons which is as shown by their electronic configuration - 1s²2s²2p⁶. Hence, they are highly stable and don't react with other elements. Ex - Helium, Argon, Neon etc.

Fossils of sea creatures have been found near the top of Mount Everest (8848m above the sea level). How do you think they could have got there?
Explanation:
The fossils can be found on top of mount Everest due to regional uplift of the crust.
Mount Everest is located a along a convergent margin between two tectonic plate. Due to similarity in density between the two margins, when they collide, there is tectonic build up.
Sedimentary rock layers originally at sea levels are uplifted to those tower peaks as the plate continues to grind against each other.
Most sedimentary rocks contains fossils. As the grinding continues, the uplift and deformation continues.
