can someone pleasee choose the correct answer xx

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.

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.

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.

A bird is flying at 10 miles per hour east: Speed = 10 miles per hour, velocity = 10mph in eastward direction, Acceleration = 0 m/s².

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)

Plants are multicellular eukaryotic organisms with cell walls made of cellulose. Plant cells also have chloroplasts. In addition, plants have specialized reproductive organs. These are structures that produce reproductive cells. Male reproductive organs produce sperm, and female reproductive organs produce eggs. Male and female reproductive organs may be on the same or different plants.

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.

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.
