Briefly explain how each layer interacts with electromagnetic radiation from the sun by describing the temperature changes that occur
Explanation:
The layers of atmosphere are differentiated on the basis of different temperature gradients.Thus,different layers within the atmosphere are created.
Toposphere is heated from the ground. Thus, with increase in altitude temperature decreases.
In the stratosphere, temperature increases with altitude. The direct heat source for the stratosphere is the Sun. Air in the stratosphere is stable because warmer, less dense air sits over cooler, denser air.
In Mesosphere temperature decreases with altitude. Few gas molecules present in mesosphere absorb sun's radiation.The heat source is the stratosphere below. The mesosphere is extremely cold, especially at its top, about -90°C.
Thermosphere which also contains ionosphere.The density of molecules is so low in here that one gas molecule could easily go upto 1 km before it collides with another molecule. It is so little energy is transferred, the air feels very cold

9. What type of bond is pictured in the image below?
a. covalent bond
b. ionic bond
c. metallic bond
d. electron bond
ONLY 9
Answer:
c. metallic bond
Explanation:
Metallic bonding, unlike other forms of atomic bonding, involves delocalized elections. The negatively charged electrons form a "sea" around metal cations. Electrons within the valence shells of metals are only held loosely within their molecular orbits- the metals are held together due to the strong attraction between these delocalized electrons and positive nuclei.
The electrons are typically described as mobile, free, and delocalized. These traits are responsible for several metallic properties such as:

How are rocks and air alike? A. People use them to build things. B. They are on the ocean floor. C. They are natural resources. D. People need them to live.
Answer:
i think its c
Explanation:
Answer: C.
Explanation: Natural resources are resources that exist without any actions of humankind. Basically materials or substances such as minerals, forests, water, and fertile land that occur in nature and can be used for economic gain. Rocks are a source of natural resources and so is air. If the answer is not correct, then it must be D.

Answer:
false
Explanation:
edge 2020
Conscious awareness of posthypnotic suggestions is a false statement because it creates a subconscious.
What are posthypnotic suggestions?The directive was given to the subject during a hypnotic trance that must be carried out once the subject awakens.
A post-hypnotic suggestion is essentially a specific directive to be followed after the hypnotherapy session to the subconscious.
An illustration of this would be going to a hypnotist for help with weight reduction and having the suggestion made that every time you feel like a sweet sort of meal, you will feel like drinking some water instead" ingrained in your subconscious.
Therefore posthypnotic suggestions of having conscious awareness are false statements.

Why is meiosis important in maintaining genetic diversity?
Question 6 options:
A Meiosis creates diversity by cutting each chromosome exactly in half.
B The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.
C It creates sex cells (eggs or sperm) that have exactly the same alleles (version of a gene) as the parents.
D The chromosomes in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy.
Answer:
We now know that meiosis is the process of chromosomal reduction which allows the production of haploid germ cells necessary for sexual reproduction. Meiosis is furthermore important for its role in enabling genetic diversity and facilitating the repair of genetic defects through recombination.
Explanation:
Brainliest please?
Meiosis is a specialized form of a cell division in which number of chromosomes is reduced to half. The reduction in chromosome number is achieved by one round of DNA replication and two rounds of chromosome segregation.
Meiosis produces genetic variation by the process of recombination.Recombination occurs when two molecules of DNA exchange pieces of their genetic material. The process of recombination occurs during the prophase stage of meiosis I. In meiosis, crossing over occurs between the non-sister chromatids in a homologous pair (one from each parent) of chromosomes.The correct answer is option B. The two different chromosomes of the organism producing the sex cell (egg or sperm) are mixed up during crossover, creating a new combination of alleles.
Other options-
A. Meiosis creates diversity by cutting each chromosome exactly in half - incorrect .In meiosis the chromosome number is reduced to half.
C. It creates sex cells (egg or sperm) that have exactly the same alleles (version of a gene) as the parents-incorrect. The sex cells produced are not genetically identical to the parent cell.
D. The chromosome in meiosis are copied so they are exactly the same as the organism producing the gamete, except they have just one copy-incorrect. In meiosis the chromosomes are not exactly copied.

Describe the way convection works and how it might work within the earth? -geology question
Answer:
Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements.

Which biomolecule provides the instructions to build enzymes?
A. Carbohydrates
B. Lipids
C. Nucleic acids
D. Proteins
Proteins are the building blocks of enzymes, and proteins are made up of amino acids that are linked together in one or more polypeptide chains. Therefore, option (D) is correct.
What are enzymes?Enzymes are proteins that aid in the acceleration of metabolic processes, also known as the chemical reactions that take place in our bodies. They are responsible for the creation of some chemicals while also decomposing others. Enzymes are present in everything that is alive. Enzymes are something that are produced by our bodies spontaneously.
Enzymes regulate most biochemical reactions in animals, plants, and microbes, thus there are many examples. Animal digestive enzymes are well-known. Gastric juices break down food with the enzyme pepsin. Salivary amylase turns starch into sugar, starting digestion.

When a bee visits a flower for sweet, sweet nectar, the plant's gametes are also spread to anoher plant. What kind of symbiotic relationship is this?
Answer:
Mutualism
Explanation:
Mutualism is a type of symbiotic relationship in which the two species of organisms involved benefit from one another i.e. the actions of one benefits the other.
In this question, a bee is said to visit a flower for sweet nectar, however, in the process of feeding on the flowers nectar, the plant's gametes are also spread to another plant by the bee. This is a type of MUTUALISTIC RELATIONSHIP because the plant is beneficial to the bee by providing food (nectar) while the bee also helps the plant by helping it pollinate.
Identify the control group for the rat experiments described in the Paralytic Shellfish Poisoning Scenario.
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, the control group of an experiment is the group in which every other group of the experiment is firstly compared with. This is because control groups are usually not administered with any form of treatment. Thus, the control group of the experiment/scenario referred to in the question will be the group that did not receive any form of treatment and was probably given water or placebo.

how is atmospheric carbon in the form of CO2 converted into a molecule that is usable to all organisms?
Answer:
The carbon-dioxide exists in the atmosphere, and it is dissolved in the water.
Explanation:
With the process of photosynthesis, it becomes organic, and by breathing, the organic gas goes back to carbon-dioxide.
The assimilation of carbon is the process when the carbon-dioxide converts to organic carbon with the help of living organisms. This organic carbon is then used for energy.
