This graph represents the velocity of a car that is exiting the highway. Which best describes its motion?
it's slowing down because of the time increase
it's speeding up because of the straight line
it's moving at a straight line
it's not moving at alll
Answer:
It's slowing down because of the time increase
Explanation:
As shown by the graph, as more time passes, the velocity slowly decreases. This means that as the time goes on, the car is slowing down.
Answer: It's speeding up because of the straight line

Analyze the model of the cell membrane below. Which of the following statements is true about the phospholipid components of the cell membrane? Both components of the phospholipids are hydrophobic. Both components of the phospholipids are hydrophilic. The tails are hydrophilic while the heads are hydrophobic. The tails are hydrophobic while the heads are hydrophilic.
Answer:
This question appears incomplete but The correct option is the last option
Explanation:
Cell membranes are made up of a lipid/phospholipid bilayer in which each layer consists of an hydrophilic head (water loving) and a hydrophobic tail (water fearing). The hydrophobic tail of each layer is oriented inward and the hydrophilic heads are oriented outward so the cell can interact with water molecules inside (the cytoplasm) and outside the cell environment. This orientation forms a critical part of the function of the cell membrane that makes it a selectively permeable barrier that regulates what goes in and out of the cell.
In a chemical
compound, what things are being
put together?
The different atoms are being put together in a chemical compound.
What is a Chemical compound?A chemical compound may be defined as any form of substance that is composed of similar types of molecules comprising atoms of two or more chemical elements. These compounds have specific characteristics based on their appearances and chemical structure.
These different atoms are linked together covalently to each other in a linear or somehow branched chain in order to construct chemical compounds. Such chemical compounds are derived as pure substances.
Chemical compounds are derived in such a way that when two or more elements of either similar or diverse characteristics are combined through a chemical reaction. Such types of compounds are definitely formed with the help of numerous chemical bonds.
Therefore, the different atoms are being put together in a chemical compound.

Answer:
a) x4 b) Eyepiece x10 Objective x40
Explanation:
a) x4 magnification
The 4x objective lens has the lowest power and, therefore the highest field of view. As a result, it is easier to locate the specimen on the slide than if you start with a higher power objective.
b)
Eyepiece Lens: the lens at the top of the microscope that you look through. The eyepiece is usually 5x, 10x or 15x power.
Objective Lenses: Usually you will find 3 or 4 objective lenses on a microscope. They almost always consist of 4x, 10x, 40x and 100x powers.
To get 400 we need to use a combination that, multiplied together, will give us 400.
If the eyepiece lens is 10x then 400/10 = 40
So if we use the 10x Eyepiece lens with the 40x Objective Lens we will get a total magnification of x400.

O leaves
O sand
O dogs
PLEASE HELPPP
Answer:
sand :)
Explanation: Because leaves and dogs have cells but sand isn't made of cells but it is made of chemicals. Sand is not a living thing but leaves and dogs are .
Answer:
Sand
Explanation:
All living things are made up of one or more cells.
Leaves are plants and dogs are animals. Plants are animals are living things, therefore they must have cells.
Sand is made up of rocks and minerals that have been broken down into small pieces. Sand is not living, so it doesn’t have any cells.
Therefore, the correct answer is sand. Sand is not alive and has no cells.

Elizabeth and Steven are pushing the cabinet to the right. Elizabeth applies 5 a force of 40 N and Steven exerts a force of 55 N. What is the Net Force? O 15 N Left 15 N Right 95 N Left O 95 N Right
Answer:
95 N right
Explanation:
Given that,
Both Elizabeth and Steven pushes the cabinet to the right. Elizabeth applies 5 a force of 40 N and Steven exerts a force of 55 N.
As both forces are acting in same direction, they will add up. Net force is given by :
F = 40 N + 55 N
F = 95 N in right direction
Hence, the correct option is (d) "95 N right".
