When bacteria reproduces asexually are the offspring uniform or diverse?
Bacteria reproduces asexually and produce genetically identical offspring. They produces a large number of offspring quickly and all will be uniform.
What is binary fission?Binary fission is the asexual method of reproduction in bacteria. Asexual reproduction creates clones of the original parent, which results in kids that are genetically identical to the parent.
Asexual reproduction allows for the rapid production of vast numbers of children by a single person. Asexual reproduction is a successful method of reproduction in a stable or predictable environment since all the children will be suited to that environment.
Asexually reproducing organisms may be at a disadvantage in an unstable or unpredictable environment since all of the progeny are genetically similar and might not have the genetic diversity to survive in new or changing settings.

What does c represent in the carbon cycle diagram?
Answer:
carbon
Explanation:
I'm pretty sure if not
Answer:
The adjacent diagram shows the carbon cycle with the mass of carbon, in gigatons of carbon (Gt C), in each sink and for each process, if known. The amount of carbon being exchanged in each process determines whether the specific sink is growing or shrinking.
Lithium hydroxide reacts with hydrobromic acid(HBr) to produce lithium bromide and water. If you
start with 3.00 moles of lithium hydroxide, how many moles of lithium bromide will be produced?
Answer:
3.00 moles of Lithium bromide will be produced
Explanation:
The reaction that takes place is:
LiOH + HBr → LiBr + H₂OBy looking at the reaction equation, we can see that the reaction of 1 mol of lithium hydroxide (LiOH) produces 1 mol of lithium bromide (LiBr). Thus, 3.00 moles of LiOH would conversely produce 3.00 moles of LiBr.

A field of science that studies atoms and molecules is called _______
A field of science that studies atoms and molecules is referred to as chemistry.
What is chemistry?Chemistry is the discipline of science that examines the attributes, composition, and framework of elements and compounds, as well as the energy released or absorbed once they change.
Food, apparel, shelter, health, power, and clean air, water, and soil are all dependent on chemistry.
Chemical technologies improve our quality of life in a variety of ways by fixing issues in health, equipment, and energy usage.
Respiration, digestion, photosynthesis, cooking food, burning fuel such as coal and petroleum, cleaning garments and utensils, and many more are examples of chemistry in everyday life.
All of these activities occur in our daily lives and are subjected to chemical reactions.
Thus, chemistry is the field of science that studies atoms and molecules.

Explanation:
complete combustion of wax takes place in non-luminous zone of a candle flame.
Answer:
A complete combustion of wax takes place in outer zone of a candle flameExplanation:
The middle zone is yellow and luminous because As it is an oxygen-depleted zone, insufficient oxygen exists to burn all of the wax vapor. ... The outer zone is the area where the flame is the hottest and complete combustion of wax takes place.How many moles is 118 grams of Argon
Answer:
[tex]\boxed {\boxed {\sf About \ 2.96 \ moles \ of \ Argon}}[/tex]
Explanation:
To convert from grams to moles we must use the molar mass, which is found on the Periodic Table.
Argon: 39.9 g/molUse the molar mass as a ratio.
[tex]\frac{39.9 \ g \ Ar}{1 \ mol \ Ar}[/tex]
Multiply by the given number of grams: 118
[tex]118 \ g \ Ar *\frac{39.9 \ g \ Ar}{1 \ mol \ Ar}[/tex]
Flip the fraction so the grams of argon will cancel each other out.
[tex]118 \ g\ Ar * \frac{1 \ mol \ Ar}{39.9 \ g \ Ar}[/tex]
[tex]118 * \frac{ 1 \ mol \ Ar}{39.9 \ g \ Ar}[/tex]
[tex]\frac {118 \ mol \ Ar }{ 39.9 }[/tex]
[tex]2.95739348 \ mol \ Ar[/tex]
The original measurement of grams had 3 significant figures, so our answer must have 3 sig figs.
For the number we calculated, that is the hundredth place. The 7 in the thousandth place tells us to round the 5 to a 6.
[tex]2.96 \ mol \ Ar[/tex]
There are about 2.96 moles of Argon in 118 grams.

B)Ocean water to the south of Arizona is warm.
C)Winds at this latitude tend to blow from west to east.
D)Land masses heat up more quickly than oceans.
Answer:
B)
Explanation:
This should be the correct answer, lmk if it's not
As in the given image, the weather pattern known as Arizona monsoon is caused by the winds at this latitude tend to blow from west to east. Thus, option C is correct.
What is Arizona monsoon?The Arizona Monsoon is a well-defined meteorological phenomenon that affects the southwest region of North America during the summer. It is scientifically referred to as a meteorological "singularity."
Arizona experiences its strongest wind flow during the winter months from the west or northwest, coming from California and Nevada. The winds change to a southerly or southeasterly direction as the summer months approach.
From the Pacific Ocean and the Gulf of Mexico, moisture moves northward. Statewide moisture conditions are drastically altered as a result of this alteration.

Mr. Avogadro has set up 4 jars with one mole of each the following substances:
1. Iron
2. Sodium Chloride
3. Sodium Bicarbonate (NaHCO3)
4. Aluminum
His clever and intelligent students notice that all of the amounts of the various
substances are different from one another, even though they are all ONE MOLE.
Explain the reason why each amount in the jar is different in terms of the mole. Then,
calculate the molar mass for each of the substances. Circle your your answers and
include the unit used for molar mass.
Answer:
Although they have the same mole, they have different molar masses because of their chemical composition.
1. Iron: 55.845 g/mol
2. Sodium Chloride: 58.44 g/mol
3. Sodium Bicarbonate (NaHCO3): 84.006 g/mol

What mass of Na2CO3 is required to create 750 mL of an aqueous solution where the concentration of the carbonate (CO3-2) ions is 1.75 M? (assume complete dissociation)
Answer:
139.11 grams
Explanation:
The molarity (M) is equal to m (moles) /L (liters).
Notice how it is in mL so converting it would be 0.75 L (750*10-3)
Now plug in the information
1.75=m/0.75
m=1.3125
Now m is in moles so convert to grams to get the mass
1.3125 mol Na2CO3 * 105.9888 g Na2CO3 = 139.1103
