What is litmus paper? How is it used to determine if a compound is an acid or base?
Answers
Answer:
Litmus paper is a tool used to test whether a substance is an acid or base. When a substance is dissolved in water, the resulting solution causes the litmus paper to change color. The acidity or alkalinity of a solution is determined by the concentration of hydrogen ions, or power of hydrogen, expressed as a pH value.

A bird is flying at 10 miles per hour east: Speed = 10 miles per hour, velocity = 10mph in eastward direction, Acceleration = 0 m/s².
What is speed, velocity and acceleration?Speed is the rate at which an object covers distance; Velocity is the rate at which an object changes its position in a particular direction and Acceleration is the rate at which an object changes its velocity over time.
(1) Speed = 10 miles per hour
Velocity = 10mph in eastward direction
Acceleration = 0 m/s²
(2) Speed = The car's speed when traveling at 50 miles per hour is 50 miles per hour. When the car slows down to 20 miles per hour, its speed becomes 20 miles per hour.
Velocity = initial velocity is 50 miles per hour in the direction of travel. When it slows down to 20 miles per hour, its velocity becomes 20 miles per hour in the same direction.
Acceleration = Acceleration = (20 miles per hour - 50 miles per hour) / 10 seconds
= -3 miles per hour per second
(3) Speed = 2 feet per second
Velocity = Cannot determine
Acceleration = Cannot determine
(4) The distance traveled in a given time is known as "displacement"
(5) Speed = 2 meters per second east.
Velocity = 2 meters per second north
Acceleration = zero
(6) Speed = 5 meters per minute.
Velocity = 5 meters per minute east
Acceleration = cannot determine
(7) Speed = 70 miles per hour
Velocity = 70 miles per hour (North)
Acceleration = cannot determine
(8) Speed = 1/3 miles per hour
Velocity = 1/3 miles per hour
Acceleration = 0 miles per hour per hour
(9) Speed = Cannot be determined
Velocity = Cannot be determined
Acceleration = Cannot be determined
(10) Speed = 3 meters per second
Velocity = 3 meters per second
Acceleration = 0 meters per second per second (since light always travels at a constant speed and does not accelerate)

1. What factors shaped the cliffs of Victoria, Australia over time?
2. How do you know a rock has been or is being weathered?
3. How are weathering and erosion different?
Answers
Answer:
Explanation:
1.The powerful surf and the salt of the erratic and moody Southern Ocean started to erode the rugged limestone cliffs along Victoria's Coastline.
2.Animals that burrow underground, such as moles, gophers or even ants, can also cause physical weathering by loosening and breaking apart rocks. Dens and tunnels are signs of this type of weathering. Other animals dig and trample rock on the Earth's surface, causing rock to slowly crumble apart.
3.When the smaller rock pieces (now pebbles, sand or soil) are moved by these natural forces, it is called erosion. So, if a rock is changed or broken but stays where it is, it is called weathering. If the pieces of weathered rock are moved away, it is called erosion.

describe the cellular evidence that both plant and animal cells obtain energy through cellular respiration.
Answers
Answer:
Explanation:
The glucose required for cellular respiration is produced by plants. Plants go through a process known as photosynthesis. Photosynthesis can be thought of as the opposite process of cellular respiration. Through two processes known as the light reactions and the dark reactions, plants have the ability to absorb and utilize the energy in sunlight. This energy is then converted along with water and carbon dioxide from the atmosphere into glucose and oxygen. Since this is the opposite process of cellular respiration, plants and animals are said to have a symbiotic relationship. This means that plants and animals live together and benefit from each other.
The rate of photosynthesis can be determined by measuring the rate that reactants are used up by a plant or by measuring the rate that products of photosynthesis are produced by a plant. How would placing a plant in a dark room for 24 hours affect the rate of photosynthesis?
A. The rate of photosynthesis would increase and the plant would take in more water.
B. The rate of photosynthesis would decrease and the plant would produce more sugar.
C. The rate of photosynthesis would increase and the plant would produce more oxygen.
D. The rate of photosynthesis would decrease and the plant would take in less carbon dioxide.
Answers
Answer:
The answer is D.
The photosynthetic reaction produces oxygen and sugar. When a plant is placed in the dark then the rate of photosynthesis decreases due to less intake of carbon dioxide, Thus, option D is correct.
What is photosynthesis?Photosynthesis has been said a reaction that uses light energy to form chemicals like glucose and carbon dioxide. The rate of photosynthesis is determined by the product formation from the reactants consumed.
Light is a factor that determines the rate of photosynthesis as solar energy is used to split the water molecule and carbon dioxide to produce oxygen and sugar molecules.
The concentration of carbon dioxide and sunlight are rate-determining limiting factors. Less amount of carbon dioxide will be available for plants to intake and hence less reactant will be produced.
Therefore, option D. less carbon dioxide will be present in the room.
