During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate). Summary, Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
Which statement describes an advantage of asexual reproduction?
O Asexual reproduction results in variations in DNA.
o Asexual reproduction causes less competition for resources.
o Asexual reproduction is faster tha sexual reproduction.
O Asexual reproduction requires more energy than sexual reproduction.
Activity
Asexual reproduction is faster tha sexual reproduction.
In asexual reproduction there is mitosis. There is prophase, metaphase, anaphase, and telphase. In sexual reproduction there is meiosis. Meiosis does have prophase, metaphase, anaphase, and telophase. But it has two stages of that. So it also has prophase 2, metaphase 2, anaphase 2, and telophase 2,

Which of the following would be a good choice of metal spoons to stir a
solution of lead(II) nitrate?
A. Silver
B. tin
C. nickel
D. Fe
Answer:
A. Silver
Explanation:
In order to answer this question accurately, we must have a good knowledge about the position of metals in the electrochemical series.
We must know that metals that are high above in the electrochemical series displace metals that are lower in the series from their aqueous solution. This means that tin, nickel and iron can all displace the lead from the solution of lead(II) nitrate.
However, silver is far less reactive than lead so it can not displace lead from its aqueous solution, hence the answer above.

Answer:
False
Explanation:
Just because their hair is their doesn't mean they where their during that time period or their at all. It could have been brought in by someone else's clothes.
Please award me brainliest
We can determine the culprits by extracting the fingerprints and DNAs from the hair strand taken from the crime location. But if suspected one's hair is not found from the scene does not indicated that he or she was not involved in the crime. Hence, the statement is false.
What is forensic tests?Forensic laboratories tests samples from crime scenes. There are various advanced testing methods which helps to identify the culprits of a crime. For example the hair and fingerprints, clothes or any chemical materials, blood etc. obtained from the crime scene are tested to identify its owner.
Hair is made of proteins. From each hair strand we can extract a number of DNA molecules. Thus a hair strand obtained from a crime scene can be tested and can identify its owner.
However, sometimes there will be no evidences such as hair or blood in the crime location or sometime the may some samples which are not related the culprits.
Hence, it cannot be said that if there is no hair or any sample related with the suspected one from the crime scene, that they could be exonerated. Thus the statement is falls and he/she can be a culprit which can be proved in another way.

Xenon-60 In order, what is the number of protons, electrons, and neutrons.
60,6,6
54,54,6
6,54,54
Answer:
I would say B?
54,54,6
Explanation:
The element in Group 14 Period 4 has how many neutrons and is it a metal, nonmetal, metalloid or noble gas.
Number of neutrons=41, and it is metalloid
Further explanationGroup 14⇒valence electron = 4(ns²np²)
Period 4⇒n=4
So electron configuration of the element :
1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p² = 32 electron=atomic number
The element with atomic number 32, which is in period 4 and group 14 is Ge-Germanium
There are seven elements that can be classified as metalloids, namely boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and polonium (Po).
While the mass number: 73
So the number of neutrons = mass number-atomic number

A 48.9 g piece of aluminum is dropped in a graduated cylinder partially filled with water. The original volume of water in the cylinder was 41.8 mL. The water rose to 54.4 mL when the aluminum was dropped in. What is the density of the aluminum?
Answer:
3.88g/mL
Explanation:
Density could be understood as the mass of a compound when it occupies 1mL.
To find the mass in 1mL we need to determine the volume that the piece occupies:
Based on Archimedes' principle, the volume of water displaced is equal to volume of the aluminium piece, that is:
54.4mL - 41.8mL = 12.6mL
As the piece has as mass 48.9g, the density is:
48.9g / 12.6mL =
3.88g/mLIs this equation completely balanced?
2C8H8 + 25O2 = 8CO2 + 18H2O
A. No, because the number of carbon, hydrogen & oxygen atoms on both sides of the equation are not equal.
B. No, because the number of oxygen atoms on both sides of the equation are not equal.
C. Yes, because all of the coefficients are in their lowest whole number ratio.
D. No, because the number of hydrogen atoms on both sides of the equation are not equal.
E. Yes, because the number of products is equal to the number of reactants.

A ring made of pure gold contains 5.29 x 1022 atoms. How many moles are in the ring?
Answer:
0.088 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\ [/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have

what happens to the radius of the atoms of an element as you go down a column of the periodic table ?
Answer:
Increases
Explanation:
The atomic radius increases as you go down a periodic table. Across a period which is a row, the atomic radius reduces.
The atomic radius is taken as the half of the inter-nuclear distance between two covalently boned atoms of non-metallic elements. It is also, half of the distance between two nuclei in the solid state. Across a period in the periodic table, atomic radii decreases progressively from left to right. Down a group it increases from up down.This woman is riding a bicycle down a hill at a constant speed and in a straight line. Which change will increase the speed of the bicycle?

what happens to the radius of the atoms of an element as you go towards the right in a row of the periodic table ?
Answer:
It decreases
Explanation:
As one moves from left to right on the periodic table, the radius of atoms reduces due to the nuclear pull.
The size of an atom estimated by the atomic radius is taken as half of the internuclear distance between the two covalently bonded atoms of non-metallic elements. Across a period, atomic radius decreases progressively from left to right. This is due to the increasing nuclear charge without attendant increase in the number of electronic shell.
