White arctic hares blending in with the white snow in their environment is an example of what type of camouflage?
A. hiding
B. protective resemblance
C. mimicry
D. protective coloration
Answers
Answer:
The answer to your question is A.
D. Protective coloration. Protective coloration, also known as "crypsis," is a defense mechanism used by animals to avoid detection by predators or prey.
An illustration of protective coloration, which is a sort of camouflage, is how white arctic hares blend in with the white snow around them. Animals use protective coloration, commonly referred to as "crypsis," as a defensive strategy to evade being seen by predators or prey.
In this instance, the white arctic hares' fur is the same shade as that of their snowy environment. Their chances of survival are increased by this merging, which enables them to remain unnoticed and effectively hidden from predators like polar foxes or birds of prey. They have a better chance of escaping or avoiding detection when they are well-camouflaged, making it difficult for predators to see them against the white background.

Imagine you are at your favorite beach. The sun is shining and you are enjoying the ocean breeze. The temperature is about 89F. You take your shoes off and realize that the sand is almost too hot to walk on. You run to the water's edge to wet your feet after the walk over the sand and realize that the water is almost too cold. Explain the temperature difference between the sand and water using Thermodynamics.
Answers
Answer:
The specific heat of water is more specific than the heat of sand, therefore, it will take more energy to raise the same amount of water with the same temperature.
Explanation:
The temp is 89 F so, 31.67° C
The specific heat of the water is 4.184 J/g° C
The specific heat of the sand is 0.290 J/ g° C
The heat is the amount of energy that is needed to raise the temp. of the substance
You will need a lot more energy to raise the temp of the water then of the same amount of sand, therefore, because of the specific lower heat of the sand it will raise it's temperature quicker compared to water.

Answers
Answer:
[tex]\boxed {\boxed {\sf A. \ SiCl_4}}[/tex]
Explanation:
We are given the compound name: silicon tetrachloride.
Silicon is a metalloid and chlorine is a nonmetal, therefore we must use the rules of molecular compounds. Molecular compounds use prefixes to name the compounds. Break up the compound into 2 parts.
1. Silicon
The first element: silicon, has no prefix. Therefore, a prefix of mono (1) is implied.
2. Tetrachloride
The -ide suffix is added to the second element, so this is really chlorine. The prefix of tetra means 4.
So there is 1 silicon (Si) atom and 4 chlorine (Cl) atoms. The formula must be SiCl₄

What volume will 3.50 mol of ammonia gas occupy at conditions of standard temperature and pressure?
Answers
Answer:
Q:
What volume will 3.50 mol of Xe gas occupy at STP?
A:
78.4 L
Explanation:
The volume occupied by 3.5 moles of ammonia gas at standard temperature and pressure (STP) is 78.45 L
Data obtained from the question Number of mole (n) = 3.5 moles Pressure (P) = STP = 1 atm Temperature (T) = STP = 273 KGas constant (R) = 0.0821 atm.L/Kmol Volume (V) =? How to determine the volume
The volume of the gas at standard temperature and pressure (STP) can be obtained by using the ideal gas equation as illustrated below:
PV = nRT
1 × V = 3.5 × 0.0821 × 273
V = 78.45 L

find out the number of moles and use the molar ratio (numbers in front of formulas (in this case they are all 1) to determine how many moles of each product you are going to get theoretically
n=m/M is the equation to use to get moles here
30.8 gm/32.04 g/mol=0.9612 moles of the methanol and also of the formaldehyde so
0.9612 moles of the formaldehyde x molar mass (M) 30.73 g/mol= 29.54 gm which is the theoretical yield you already have the actual yield of 24.7 gm
then divide the actual by the theoretical to get the % yield which is 83.6%

Using the concept of Avogadro's number, the number of atoms present is 4.4 * 10^24 atoms.
What is Avogadro's number?Professor Avogadro provided a nice way of calculating the number of atoms in a molecules by the use of the Avogardro's number. Now we know that 1 mole of a substance contains about 6.02 * 10^23 atoms, molecules ions etc.
Hence;
1 mole of sulfur dioxide contains 6.02 * 10^23 atoms
7.32 moles of sulfur dioxide contains 7.32 moles * 6.02 * 10^23 atoms/1 mole
= 4.4 * 10^24 atoms.

Answers
Answer:
C
Explanation:
For an organism scientific names the first part is the genus and the second is the species
For an organism’s scientific names, the first part is the genus and the second is the species. Therefore, the correct option is option C.
What is organism’s scientific name?The genus name and particular epithet make up the binomial name. Italicization is used for species names. The specific epithet comes after the genus name and therefore is not capitalized; the genus name is usually capitalized and written first. This is true without exception.
A scientific name has two components. Genus name comes first, followed by species name. If typed, it is always in italics or underlined (handwritten). Genus names always begin with a capital letter. The initial letter of the word species is not capitalized, though. For an organism’s scientific names, the first part is the genus and the second is the species.
Therefore, the correct option is option C.
