Please Helppp Im So Confused

Answers

Answer 1
The answer would be 2 Na+ MgCl2–> 2 NaCl+ Mg

To balance out the equation you can see that the Chlorine isn’t balanced so you find a number that can be the coefficient, which is 2.

Na+ MgCl2—> (2)NaCl+Mg

Then you need to balance out the Na in the reactant part, which will also be 2.

(2)Na+ MgCl2–> (2)NaCl+ Mg

And there’s your answer

Definitely the answer is B

UAGOUU is a messenger RNA strand that encodes this information.

What is Messenger RNA?

Single-stranded RNAs of the type known as messenger RNA, or mRNA, are used to make proteins. mRNA is created during transcription from a DNA template.

The function of mRNA is to transport protein information from DNA in the cell's nucleus to the cytoplasm (watery center), where the machinery responsible for producing proteins reads the mRNA sequence and converts each three-base codon into an amino acid that will eventually create a protein.

mRNA, or messenger RNA. Therefore, mRNA is actually a type of nucleic acid that aids in the cellular machinery's ability to read the human genome, which is encoded in DNA.

Can you give the definitions to the words below?

Frequency, wavelength, and energy

Electromagnetic energy

Reflection, Refraction, Absorption

3 States of Matter

Categories of Biodiversity

Answers

Answer:

Frequency: The rate that sound or other waves vibrate at

Frequency: The rate at which something happens

wavelength: wavelength -- the distance (measured in the direction of propagation) between two points in the same phase in consecutive cycles of a wave

wavelength: wavelength -- a shared orientation leading to mutual understanding; "they are on the same wavelength"

energy: Power that makes machinery work

energy: The physical and mental effort used to do things

Electromagnetic energy is a term used to describe all the different kinds of energies released into space by stars such as the Sun. These kinds of energies include some that you will recognize and some that will sound strange. They include: Radio Waves. TV waves.

Reflection: A reflection shows what something is like

Reflection: The image that reflected from or in something

Refraction: refraction -- the change in direction of a propagating wave (light or sound) when passing from one medium to another

Refraction: deflection, deflexion, refraction -- the amount by which a propagating wave is bent

Absorption: absorption, soaking up -- a process in which one substance permeates another; a fluid permeates or is dissolved by a liquid or solid

Absorption: absorption -- the physical process in which incident radiated energy is retained without reflection or transmission

Absorption: concentration, engrossment, absorption -- complete attention; intense mental effort

Absorption: preoccupation, preoccupancy, absorption, engrossment -- the mental state of being preoccupied by something

Absorption: assimilation, absorption -- the absorbing of one cultural group into harmony with another

3 States of Matter: There are three very well-known states of matter: Solids, Liquids, and Gases.

Categories of Biodiversity: Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms.

Explanation:

Sorry for being late, I was answering but had to do something.
