Marianne is conducting an experiment on homeostasis in paramecium which is a type of single celled organism. Which of these observation

Answers

Answer 1

Answer:

Contractile vacuole is responsible for maintaining the homeostasis in paramecium.

Explanation:

The observation of this experiment is that contractile vacuole is responsible for maintaining the homeostasis in paramecium because the contractile vacuole regulates the quantity of water inside a cell. Contractile vacuole controls the water balance in the body by absorbing and removing the excess amount of water out of the cell. This function of contractile vacuole allows the cells to survive under hypotonic stress that is present in the pond water or any other stressful environment.

Beaker A= Isotonic

Beaker B = Hypotonic

Beaker C= Hypertonic

Explanation:

ISO means the same on each side.

Hypo means less.

Hyper means more.

Beaker A= Isotonic

Beaker B = Hypotonic

Beaker C= Hypertonic

what is the difference between Isotonic Hypotonic Hypertonic?

Isotonic: Isotonic solutions are solutions having equal osmotic pressures.Hypotonic: Hypotonic solutions are solutions having lower osmotic pressures.Hypertonic: Hypertonic solutions are solutions having comparatively higher osmotic pressures.

The main difference between isotonic hypotonic and hypertonic solutions is that isotonic solutions are solutions having equal osmotic pressures while hypotonic solutions are solutions having lower osmotic pressure and hypertonic solutions are solutions with high osmotic pressure.

What force or forces constitute the fundamental source of energy that generates wind movement and circulation?

Answers

Answer:

The movement of wind is the result of the action of one or more forces on a particle of air, fundamentally the forces of the solar radiation, pressure gradient, coriolis, friction and centrifugal are recognized.

Explanation:

Air movement is caused by differential heating of the earth's surface and the atmosphere, which presents significant variations in time and space. Wind specifically refers to the horizontal movement of air parcels (which reach great distances and can persist on different time scales)Solar radiation is absorbed by the Earth, and this process is uneven. This irregular heating is what generates the wind. Pressure Gradient Force is determined by the pressure differences between two points in the atmosphere and tends to move the parcels of air from high to low pressure centers, in order to achieve barometric equilibrium. This force is responsible for causing the initial movement of the air. The Coriolis Force is an apparent force that occurs perpendicular to the direction of movement, generating a deviation in the wind path due to the rotation of the Earth (around its axis with an angular velocity). Centrifugal Force manifests itself as a radial pushing action from the center of a circle. In the atmosphere, it occurs in high- and low-pressure systems, leading outward from high- or low-pressure centers. The Friction Force is caused by the friction of the air with the earth's surface, causing a delay in the flow of air masses and changes in the direction of movement.

Oxygen gas production will happen within me

Answers

Answer:

Almost all the oxygen you breathe comes from green plants. They produce oxygen during a process called photosynthesis. During photosynthesis green plants manufacture the sugar molecules fructose and glucose. Green plants use energy from sunlight to build sugar molecules from carbon dioxide and water.

Plant cells contain organelles called chloroplasts that are essential for photosynthesis. Within chloroplasts, oxygen gas production will take place. So, the answer is chloroplast.

Plants use sunlight, water, and carbon dioxide to produce oxygen and sugar-based energy through a process known as photosynthesis. The process of photosynthesis results in the emission of oxygen gas.

Photosynthesis and release of oxygen processes occur within chloroplasts that generate energy that support plant growth and crop yield.

Although mitochondria are organelles that can be found in plant cells, they do not produce oxygen. Cellular respiration is carried out by mitochondria. Although cellular respiration consumes oxygen gas, it does not create oxygen gas.

Therefore, chloroplasts is the answer to the question "Oxygen gas production will happen within."

Which of the following data would support the claim that the gravitational force
between objects depends on mass?
O An object's weight can change depending where it is on Earth.
O A rocket can escape Earth's gravity by traveling at high speed.
O The further a planet is away from the sun, the smaller the gravitational force.
O Gravitational force is stronger on more massive planets.

Answers

Answer:

D.

Explanation:

gravitational force of attraction is stronger on more massive planets such as Jupiter

Gravitational force is stronger on more massive planets, the claim that the gravitational force between objects depends on mass, hence option D is correct.

What is gravitational force?

The force that pulls things toward the center of a planet or other body is called gravity. All the planets are kept in orbit around the solar by gravity.

Earth is subject to the same gravity pull that you are. But your force doesn't really affect our globe because Earth is so much larger than you are.

In our world, gravity the moon is maintained in its circle around Earth by gravity, as are the planets in their orbits around the sun. The gravitational force is equivalent to your weight when you are at rest on or near the Earth's surface.

Therefore, gravitational force is stronger on more massive planets, hence option D is correct.
