Answer:
Adaptations
Explanation:
1). "White" fur- Polar bears are well known for this adaptation, white fur. Their fur is actually clear, but gives the appearance of being white. This is so they can blend into their environment.
2). Fur and fat- They have very thick layers of fur and fat, to help keep them warm(insulate them), as their habitat is extremely cold. This prevents things like hypothermia and frostbite.
3). Large feet- Their feet are quite large, which gives them an advantage. It results in more even, spread out weight distribution, and gives them a better grip on the ice.
Here's an extra:
4). Greasy coat- Polar bears are excellent swimmers, and as a result of their swimming habits, they actually have a greasy coat. This grease is much like oils a duck or goose(or other aquatic aviary species) have. It causes water to roll off of them, meaning they're considered hydrophobic.
Identify the independent variable by highlighting it red. Identify the dependent variable by highlighting it yellow. 1. If I increase the temperature of the seeds, then germination will increase,
Answer:
Independent variable: temperature ; Dependent variable: germination
Explanation:
The independent variable is what is being changed in an experiment. The dependent variable is what you are measuring in an experiment.
When the independent variable is changed (in this case, temperature), it effects the dependent variable (germination).

A researcher observes the enzymatic polymerization of an organic molecule in a cell. Which enzyme is
MOST likely responsible for catalyzing the reaction?
A. a protein
O B. a nucleic acid
O C. a lipid
D. a carbohydrate
Answer:
A. a protein
Explanation:
Proteins function as enzymes in most of the catalyzing reactions, that increases the rate of reaction within cell.
Proteins are consist of multiple numbers of amino acids and the twisting and folding amino acids provide a unique identity to enzymes. Not all the proteins are enzymes but all the enzymes are proteins.
For example: Trypsin, Pepsin, and Lipases.
Hence, the correct option is "A. a protein".

An adult panda bear must eat at least 30 pounds of bamboo in a day. There are 12 adult pandas living in part of a
bamboo forest.
How many pounds of bamboo, at minimum, must be available each day in order to support the population of
pandas?
12
30
348
360
Answer: (D) 360
Explanation:
An adult panda bear must eat at least 30 pounds of bamboo in a day. There are 12 adult pandas living in part of a bamboo forest 360 pounds must available each day.
Why does panda only eat bamboo?Panda comes under the specialist because its eats only bamboo because it's present abundantly and Thus they don't have to fight with other animals to get it.
Bamboo is rich in fibre but has less nutrients, so pandas have to eat 20 to 40 pounds of the elements every day just to get by.
Thus, option "D" is correct, 360.

A-Covered shoes
B-Contact lenses
C-Goggles
D-Loose hair?
Answer:
D, loose hair.
Explanation:
If your hair is long enough, it could easily drift into the flame and catch on fire.
Answer:
D. Loose hair
Explanation:
Loose hair would be the most likely to cause an accident with an open flame.
Especially if the hair is long, it can dip down into the flame and catch on fire.
The other objects would not be interacting with the flame because they would be far away, while loose hair can reach into the area where the flame is.

Glucose is a building block of carbohydrates. Which of these best describes glucose?
A. nucleotide
B. protein
C. monosaccharide
D. lipid
Answer:
monosaccharide
Explanation:
Glucose is called a simple sugar or a monosaccharide because it is one of the smallest units which has the characteristics of this class of carbohydrates.
Glucose is the simplest monosaccharide which cannot be broken down further. Thus, option C is correct.
What is Glucose?Glucose is the primary component of carbohydrates. Glucose is a monomer made up of carbon, hydrogen and oxygen. Molecular formula of glucose is C6H12O6.
The functional group in glucose is an aldehyde present at the first carbon atom.
Glucose is called monosaccharides because it cannot be hydrolysed further. It is the simplest carbohydrate also referred as simple sugars.
Glucose molecules are chiefly linked together forming a glycosidic bond by removal of water molecule and form a disaccharide.
Glucose is chiefly produced by plants during the process called photosynthesis.
Glucose is the key component in metabolism. It provides energy to the body cells to carry out physiological activities. Glucose is found in blood.
Excess of glucose in the blood results in a medical condition called diabetes. It can be life threatening if not managed on time.

Which toy car had the greatest applied force?
A 1
B 2.
с 3
D4
Answer:
the answer is 4
Explanation:
i dont know how to explain it but i took the test and it was right.
The car with the greatest applied force is : ( D ) Car 4
Given that :
Force applied is calculated as : Mass * acceleration
Calculating the force applied on each carFor Toy car 1
mass = 0.19
acceleration = 0.15
Force = 0.19 * 0.15 = 0.0285 N
For Toy car 2
mass = 2.0
acceleration = 1.5
Force = 2 * 1.5 = 3 N
For Toy car 3
mass = 0.25
acceleration = 0.21
Force = 0.25 * 0.21 = 0.0525 N
For Toy car 4
mass = 2.5
acceleration = 3
Force = 2.5 * 3 = 7.5 N
From the answers above the car with the greatest applied force is car 4 with a force of 7.5 N
Hence we can conclude that The car with the greatest applied force is : ( D ) Car 4

What conclusions can be drawn about the existence of carbon-12, carbon-13, and carbon-14? A) These are forms of carbon and they accommodate 6 neutrons and 6 electrons but each contains a difference number of protons - 6, 7, and 8 respectively. B) These are configurations of carbon and they have 6 protons and 6 neutrons but each contains a difference number of electrons - 8, 7, and 6 respectively. Eliminate C) These are isotopes of carbon and they all contain 6 protons and 6 electrons but each contains a difference number of neutrons - 6, 7, and 8 respectively. D) These are allotropes of carbon and they consist of 6 protons and 6 electrons but each contains a difference number of neutrons - 8, 7, and 6 respectively.
Answer:
C.
Explanation:
All these carbon atoms are isotopes: they have the same amount of protons (in this case, 6 because carbon always has 6 protons) and the same amount of electrons (6 because the carbons given have a neutral charge).
Therefore, the only thing we are changing is the atomic mass and the amount of neutrons present in each isotope.
In Carbon-12, there are 6 protons, 6 neutrons, and 6 electrons.
In Carbon-13, there are 6 protons, 7 neutrons, and 6 electrons.
In Carbon-14, there are 6 protons, 8 neutrons, and 6 electrons.
Answer:
These are isotopes of carbon they both contain 6protons and 6electrons but each contains a diff about of neutrons 6,7 and 8 respectively
