Answer:
Answer: Hyperoxic alligators show significantly lower breathing rates than their siblings in normoxic and hypoxic groups. Conversely, each breath supports greater oxygen consumption in hyperoxic animals than in other groups. Statistical significance between groups was calculated by ANOVA with post hoc Tukey-Kramer
The explanation regarding the less atmospheric oxygen levels impacted the alligators growth should be because of Hyperbolic alligators.
What is Hyperbolic alligators?There should be less breathing rate and the consumption of the oxygen should be high per breath.
The compensatory cardiopulmonary remodeling, the growth of the hypnotic alligators should be constrained by the less temperature with respect to the supply of the oxygen that should limited the food utilization capacity.

What effect does pollution have on condensation? A There are more particles in the air for water vapor to cluster around. B Areas with more pollution have more clouds and rain. C Pollution creates more ground level clouds. D It is harder for the sun to warm up the water vapor.
Answer:
A There are more particles in the air for water vapor to cluster around.
Explanation:
As the condensation process takes place more particles are added to the atmosphere for water vapour and condensation further leads to the build-up of clouds. If the sky is polluted with pollutants the condensation can raise the level of pollution by blocking the rays of the sun from reaching the ground. This affects the visibility of most of the cities.How many grams of hydrogen (H2) are needed to react with 92.00 grams of nitrogen (N2)?

Which element is the excess reagent when 3.00 moles of Mg is ignited in 2.20 moles of pure oxygen
in the reaction below?
2Mg + O2 -> 2MgO
Answer:
Oxygen is in excess.
Explanation:
The coefficients of the balanced equation create a mole ratio that shows the ratio of how many reactants are used up and products are created.
The mole ratio of Mg to O2 in this equation is 2:1, which means that for every two moles of Mg used, there will be 1 mole of O2 used.
If we have 3.00 moles of Mg, we will only need 1.5 moles of oxygen to completely burn the Mg. Therefore, when all 3.00 moles of Mg are used, there will still be some of the 2.20 moles of oxygen remaining.

in what two ways do minerals form
Answer:
Minerals can form in three primary ways being precipitation, crystallization from a magma and solid- state transformation by chemical reactions (metamorphism). Mineral Precipitation is when a mineral is formed by crystallization from a solution. Examples include quartz, halite (table salt), calcite, and gypsum.
Answer:
When magma cools slowly, deep below the surface, it has time to form large crystals in regular patterns. The second way that minerals form is through solutions. (A solution is when one substance is dissolved uniformly in a liquid.) When elements and compounds leave the solution, they can crystalize.
What volume of Nitrogen measured at s.T.P. Will be produced on heating 33.8g of calcium trioxonitrate
Answer:
9.2288 L
Explanation:
The equation of the reaction is given as;
2 Ca(NO3)2 → 2 CaO + 4 NO2 + O2
From the reaction;
2 mol of Ca(NO3)2 produces 4 mol of NO2
Converting 33.8g to Number of moles;
Number of moles = Mass / Molar mass
Number of moles = 33.8 g / 164.088 g/mol
Number of moles = 0.206 mol
2 = 4
0.206 = x
Solving for x;
x = 0.206 * 4 / 2
x = 0.412 mol
At STP;
1 mol = 22.4 L
0.412 mol = x
Solving for x;
x = 0.412 * 22.4 = 9.2288 L

If you are given 608 grams of calcium phosphate Ca3(PO4)2, how many moles would you have? *
Answer:
You would have 1.96 moles.
Explanation:
You are given 608 grams of calcium phosphate Ca₃(PO₄)₂.
Molar mass (M) is the amount of mass that a substance contains in one mole. This substance can be an element or a compound.
Since the molar mass of the compound Ca₃(PO₄)₂ is 310 g / mole, and taking into account the definition of molar mass, you can apply the following rule of three: if 310 grams of Ca₃(PO₄)₂ are contained in 1 mole, 608 grams of the compound in how many moles are present?
[tex]moles=\frac{608 grams* 1 mole}{310 grams}[/tex]
moles= 1.96
You would have 1.96 moles.
What is the mass of water released by the heating? Show your work or explain your reasoning.
Answer:
Dividing the mass of the water lost by the original mass of hydrate used is equal to the fraction of water in the compound. Multiplying this fraction by 100 gives the percent water in the hydrate.
Explanation:
The amount of water throughout the compound has been determined by dividing the mass of water wasted mostly by original quantity of hydrate used. The above fraction can be multiplied by 100 to get the hydrate's water content in percentages.
What is mass ?The proportion of matter that makes up an object is quantified by its mass. The kilogram, or kg, would be the fundamental SI unit of mass.
What is hydrate?Any substance that contains water through the form of H2O molecules is referred to as a hydrate. This water content by weight can vary, but it is typically fixed. The most well-known hydrates seem to be crystalline solids which decompose once the attached water is removed.
Therefore , The amount of water throughout the compound has been determined by dividing the mass of water wasted mostly by original quantity of hydrate used. The above fraction can be multiplied by 100 to get the hydrate's water content in percentages.

What is the main function of the part labeled Yin the model?
Answer:
The part labelled Y is the chloroplast and its main function is to produce food for the plant in the reactions of photosynthesis.
Explanation:
Plants are autotrophic organisms in that they are able to manufacture their own food. Plants are able to manufacture their own food due to the presence of the cell organelle known as the chloroplast. The plant chloroplast has its own DNA and can reproduce independently, from the rest of the cell. They can as well produce amino acids and lipids required for the chloroplast membrane.
Chloroplasts are green-colored membrane-bound organelles found within the plant cell. Their green color is due to the presence of the pigment, chlorophyll. Chlorophyll in the chloroplasts are responsible for absorbing light energy from sunlight and using this absorbed energy to make simple sugars (carbohydrates) from carbon (iv) oxide and water. This is the main function of the chloroplasts in plant cells.
Photosynthesis occurs in the chloroplasts in two reaction steps:
1. The light reaction - involves the splitting of e=water molecules using the energy of sunlight
2. The dark reactions - carbon (iv) oxide from the air is used to produce sugars.

Briefly describe each of the suns layers. I’ll give brainless
Answer: The inner layers are the Core, Radiative Zone and Convection Zone.
The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona.
Nuclear fusion of hydrogen in the core of the Sun produces tremendous amounts of energy that radiate out from the Sun.
The corona is the outermost layer of the Sun, starting at about 1300 miles (2100 km) above the solar surface (the photosphere). The temperature in the corona is 500,000 K (900,000 degrees F, 500,000 degrees C) or more.
The chromosphere is a layer in the Sun between about 250 miles (400 km) and 1300 miles (2100 km) above the solar surface (the photosphere). The temperature in the chromosphere varies between about 4000 K at the bottom (the so-called temperature minimum) and 8000 K at the top (6700 and 14,000 degrees F, 3700 and 7700 degrees C), so in this layer (and higher layers) it actually gets hotter if you go further away from the Sun, unlike in the lower layers, where it gets hotter if you go closer to the center of the Sun.
The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that. The temperature in the photosphere varies between about 6500 K at the bottom and 4000 K at the top (11,000 and 6700 degrees F, 6200 and 3700 degrees C)

What is the total number of grams of solute in 500 milliliters of 1M CH3COOH (formula mass = 60)?
Answer:
30 grams
Explanation:
Molarity of a solution represents its molar concentration, and can be calculated by using the formula as follows:
Molarity (M) = number of moles (n) ÷ volume (V)
Based on the information provided, volume of solution = 500 milliliters, molarity = 1M
Volume of solution in liters = 500mL ÷ 1000 = 0.50L
Molarity = n/V
1 = n/0.50
n = 0.50moles
Using mole = mass/molar mass
Molar mass of CH3COOH (acetic acid) = 60g/mol
Mass = mole × molar mass
mass = 0.50 × 60
mass = 30 grams.
If you have 12 atoms of hydrogen before a chemical reaction, how many atoms of hydrogen will be present
Answer:
12 atoms of hydrogen will be present in the product
Explanation:
12 atoms of hydrogen will be present in the product because the law of conservation of mass states that mass is neither created nor destroyed in chemical reactions.
The law of conservation states that the mass of the element remains the same during the course of the reaction.
The law of reaction conformed by the following:-
Mass of reactant Mass of productAccording to the question, the amount of hydrogen is 12 atoms in the reactant and the amount will remain the same at the end of the reaction, which is a product that is 12 atoms
Hence, the amount remains the same in the reaction that is 12 atoms
