Answer:
There is an increase in density and a corresponding increase in the temperature of the fluid
Explanation:
The temperature and density changes occur in a fluid or gas material that cause convection to occur include increase in density and a corresponding increase in the temperature of the fluid.
This is because convection involves the movement of fluids from a hotter area to a colder area and hot fluids usually have a lower density.
please help Which diagram illustrates metaphase? A B C D
C diagram best illustrates metaphase.
What is mitosis and its stages?Prophase, metaphase, anaphase, and telophase are the four stages of mitosis.
1) Prophase: chromatin forms chromosomes, the nuclear envelope breaks down, and chromosomal centromeres bind to spindle fibers.
2) Metaphase: the chromosomes align on the metaphase plate (center of the cell)
3) Anaphase: sister chromatids are drawn to opposing poles of the cell;
4) Telophase: nuclear envelope recovers, chromosomes unroll into chromatin, and cytokinesis can begin.
hence A shows anaphase, B shows prophase and D shows telophase and cytokinesis

Answer:Peptide Bond and Water
Explanation:
The two amino acids animated above are joined together by a peptide bonds.
What do you mean by peptide bond?Along a peptide or protein chain, a peptide bond is an amide-type covalent chemical bond that connects two consecutive alpha-amino acids from C1 of one alpha-amino acid to N2 of another.
A covalent bond between two amino acids is known as a peptide bond. Peptide bonds are used by living things to make long chains of amino acids called proteins. Proteins play a variety of roles, including providing structural support, catalyzing crucial reactions.
When the carboxyl group of one molecule reacts with the amino group of the other molecule, a molecule of water H20 is released, forming a peptide bond between the two molecules.

What is the amu of a nitrogen atom?
!PLZ I WILL REWARD BRAINLIEST!
Answer:
14amu
Explanation:
Given subatomic particles:
Number of protons = 7
Number of Neutrons = 7
Number of electrons = 7
Unknown:
Atomic mass unit; amu of nitrogen
Solution:
The atomic mass unit of a substance is the number of protons and neutrons in such an atom;
Atomic mass unit = number of protons + number of neutrons
This is because the mass of an atom is concentrated in the nucleus;
For the given specie;
Atomic mass unit = 7 + 7 = 14amu

Which statement best describes the Earth’s energy budget?
The temperature increases when energy in is greater than energy out, and temperature decreases when energy out is greater than energy in.
The temperature decreases when energy in is greater than energy out, and temperature increases when energy out is greater than energy in.
Energy in never equals energy out.
Energy in and energy out are unrelated.
Answer:
Earth's energy budget accounts for the balance between the energy that Earth receives from the Sun, and the energy the Earth radiates back into outer space after having been distributed throughout the five components of Earth's climate system. This system is made up of Earth's water, ice, atmosphere, rocky crust, and all living things. Read It And Get your answer

Which two stars are most similar in luminosity?
Answer:
Procyon B and Proxima Centauri
Explanation:
Procyon B and Proxima Centauri are most similar in luminosity but Alpha Centauri and the Sun have most similar luminosity and temperature.
The primary star in the system, Procyon A, is a bright yellow-white star and one of the brightest stars in the night sky. The two stars that are most similar in luminosity are Procyon B and Proxima Centauri.
Procyon B is a white dwarf star that is part of the Procyon binary star system, located approximately 11.4 light-years away from Earth in the constellation Canis Minor.
Proxima Centauri is a red dwarf star and the closest known star to our solar system, located approximately 4.24 light-years away in the southern constellation of Centaurus. It is a part of the Alpha Centauri star system, which also includes the binary pair of stars, Alpha Centauri A and Alpha Centauri B.
To compare the luminosity of stars, astronomers often use a classification system called the Hertzsprung-Russell (H-R) diagram. This diagram plots stars based on their luminosity and temperature. Stars of similar luminosity can be found within the same region of the H-R diagram.
Therefore, the two stars that are most similar in luminosity are Procyon B and Proxima Centauri.

Predict which temperature 20 degrees Celsius, 39 degree Celsius, 50 degree Celsius you would expect a human to function best. Plan a simple investigation to test your hypothesis
Answer:
39 degree Celsius
Explanation:
Human body functions well at 36 degree Celsius. All the body functions and the enzymes secretion and processes works best on the temperature 36 degree Celsius.
The enzyme of humans will function good on temperature 39 as it is the very near to the body temperature of the human. The optimal temperature would be between temperature 35 to 40 degrees for most of the enzymes.
Testing hypothesis :
Add amylase which is an enzyme present in the saliva to a concentration sugar, which acts as the reactant in a small container having a lid. Use a thermometer to mark the changes in the temperature. We have to take two identical samples of our experiment. Place one sample at a room temperature of 25 degree Celsius and the other to be heated to 40 degree Celsius. Now we have to check the concentration of the product for each temperature. And while checking the sample which is heated, we see that at some point, the rate where the substrate is being converted in to product decreases as the enzyme denaturation and the reaction will stop. The optimal temperature is the one where the product is produced at the maximum rate.

Read the sentences.
I always spill on myself when cooking dinner. However, professional chefs themselves tend to maintain clean aprons and work areas when they cook.
Which choice correctly identifies two pronouns from the sentences?
I (reflexive), they (intensive)
I (intensive), they (reflexive)
myself (reflexive), themselves (intensive)
myself (intensive), themselves (reflexive)
Answer:
myself (reflexive), themselves (intensive)
Explanation:
"Reflexive Pronouns" refer to pronouns that are used when the subject and the object in the sentence are the same. The reflexive pronoun above is "myself." This pronoun functions as an object, but also refers to the subject "I."
"Intensive Pronouns" refer to pronouns that emphasize the noun that was already mentioned. In the example above, the intensive pronoun is "themselves" because it emphasizes the "professional chefs," which was mentioned beforehand.
It is easy to spot the reflexive and intensive pronouns because they end in "self" or "selves."
Examples: myself, yourself, himself, herself, itself, ourselves, yourselves, themselves.
Answer: myself (reflexive), themselves (intensive)

It drops as you go higher.
It is usually higher on summer days.
Its low and high are usually shown on weather map.
Which weather component is Jade describing?
Air temperature
Humidity
Precipitation
Wind speed
Answer:
Air temperature
Explanation:
Air temperature is being described by Jade according the properties highlighted.
The degree of hotness or coldness of a body is known as its temperature.
As you go higher it becomes cooler. The surface causes the warming of the air around. With height, the surface is distant from the body of air. On summer days, air temperature is higher due to more insolation. Weather maps gives a good description of air temperature from places to places.[tex]\mathrm {Hey, there!}[/tex]
Your answer is: air temperature
Air temperature drops as you go higher above.Air temperature is Higher on sunny days.Air temperature's low and high are usually shown on weather map.The answer is air temperature.
