Answer:
haploid
Explanation:
Meiosis is a type of cell division that occurs during the process of formation of gametes particularly sexually reproducing organisms.
Gametes are reproductive, sex cells that are haploid (having half the number of chromosomes as their parent cell).
Thus, during meiosis a diploid parent cell gives 4 haploid daughter cells, called gametes (such as eggs and sperms).
Answer:
the answer is haploid

What happens along a divergent boundary on the seafloor?
Multiple choice question.
cross out
A. Continental mountain ranges form.
B.Oceanic plates are subducted into the mantle.
C. New ocean crust forms.
D.Ocean basins become smaller.
Answer:
C. New ocean crust forms.
Explanation:
At divergent margins, it is true that new ocean crusts forms at the margins.
Along a divergent margin, two lithospheric plates are moving apart from one another.
Usually, when this occurs between two oceanic plates, the underlying mantle upwells to fill the void. The cooling and solidifying mantlic materials furnishes the formation of a new crust.
This is the oceanic crust.

A room is a cube that measures 4 meters in each dimension. If the temperature changes from 10 C to 30 C, and the pressure decreases from 760 mm to 718 mm Hg, would air be trying to enter or leave the room? Show tour work
Answer:
More air will enter the room since the volume of the room increases.
Explanation:
We'll begin by calculating the initial volume (V₁) of the room. This can be obtained as follow
Length (L) of room = 4 m
Initial volume (V₁) =..?
V₁ = L³
V₁ = 4³
V₁ = 64 m³
Next, we shall determine if there is an increase in the volume of the room or not. This can be obtained as follow:
Data obtained from the question include:
Initial volume (V₁) = 64 m³
Initial temperature (T₁) = 10 °C + 273 = 283 K
Final temperature (T₂) = 30 °C + 373 = 303 K
Initial pressure (P₁) = 760 mmHg
Final pressure (P₂) = 718 mmHg
Final volume (V₂) =?
P₁V₁/T₁ = P₂V₂/T₂
760 × 64 / 283 = 718 × V₂ / 303
48640 / 283 = 718 × V₂ / 303
Cross multiply
283 × 718 × V₂ = 48640 × 303
203194 × V₂ = 14737920
Divide both side by 203194
V₂ = 14737920 / 203194
V₂ = 72.53 m³
SUMMARY
Initial volume (V₁) of room = 64 m³
Final volume (V₂) of room = 72.53 m³
From the calculations made above, we can see that the volume of the room increases from 64 m³ to 72.53 m³. Thus more air will enter the room since the volume of the room increases.

When dissolved in water, all acids will
A

B

C

react with metals
When dissolved in water, all acids will form hydronium ions. The correct option is E.
Acids are chemicals that emit hydrogen ions (H+) when they are dissolved in water. However, in aqueous solutions, these hydrogen ions bond with water molecules to form hydronium ions (H3O+).
Both hydration and protonation are terms used to describe this process. The acidity of a solution is indicated by the emission of hydronium ions.
It is significant to remember that not all acids will have the same characteristics, such as changing the colour of litmus paper, feeling slick, or reacting with metals. Depending on the particular acid in question, these characteristics can change.
Thus, the correct option is E.

There are 5.5 moles of Argon gas in tank
Further explanationGiven
122.6 liters of Argon gas
Required
The number of moles
Solution
Assume at STP
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
So for 122.6 L :
= 122.6 L : 22.4 L

How many moles of silver metal are produced from 1.55 moles of copper metal? How many moles of copper(II) nitrate?
Answer:
1. 3.1 moles of silver, Ag.
2. 1.55 moles of Cu(NO₃)₂.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
Cu + 2AgNO₃ —> Cu(NO₃)₂ + 2Ag
From the balanced equation above,
1 mole of Cu reacted to produce 1 mole of Cu(NO₃)₂ and 2 moles of Ag.
1. Determination of the number of mole of silver (Ag) produced.
From the balanced equation above,
1 mole of Cu reacted to produce 2 moles of Ag.
Therefore, 1.55 moles of Cu will react to produce = 1.55 × 2 = 3.1 moles of Ag.
Thus, 3.1 moles of Ag is produced.
2. Determination of the number of mole of copper(II) nitrate, Cu(NO₃)₂ produced.
From the balanced equation above,
1 mole of Cu reacted to produce 1 mole of Cu(NO₃)₂.
Therefore, 1.55 moles of Cu will also react to 1.55 moles of Cu(NO₃)₂.
Thus, 1.55 moles of Cu(NO₃)₂ is produced

How many molecules are there in 5.9 moles of NaCl?
The number of molecules= 3.55 x 10²⁴
Further explanationGiven
5.9 moles of NaCl
Required
The number of molecules
Solution
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
So for 5.9 moles :
= 5.9 x 6.02 x 10²³
= 3.55 x 10²⁴

Which statement describes absolute and apparent brightness?
NOTES TO TAKE DOWN:
Apparent brightness is a human measurement, and it would change for each star if the measurement were taken from another location. The more precise counterpart of apparent brightness is called absolute brightness (or absolute magnitude) and is the measure of the luminosity of a star, but on a common scale.
ANSWER:
Absolute brightness is the actual amount of light produced by the star, whereas apparent brightness changes with distance from the observer.

What does the respiratory system do for
the human body?
Answer:It’s helps use take in fresh air and conduct it to carbon
dioxide.
Explanation:Our respiratory system not only helps us turn air to Co2 the frest air also helps refresh our blood when it passes through our heart.
The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system's means of getting oxygen to the blood. The respiratory system also helps to regulate the acid-base level in the blood. lastly, the respiratory system allows us to vocalize by the movement of exhaled air through the larynx.
