Why are phase changes considered physical and not chemical
changes?

Answers

Answer 1

Answer:

Phase changes are physical changes that take place when matter changes energy states, but chemical bonds are not broken or formed. ... The phase of a substance depends on the amount of energy the atoms contain. All atoms are in motion. The higher the temperature of an atom, the faster the motion

Answer 2
Because it physically change like humans and animals duuh

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."

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.

1. Mitotic cell division

Explanation:

Embryonic development is the formation of organisms that starts from the process of fertilization. The stages of development represent mitosis.

What is mitosis?

Mitosis is a part of the cell cycle, that produces two identical nuclei and daughter cells from the division of the cell and replication of the parent cell.

From the diploid parent cell, two diploid daughter cells are produced in mitosis. This process is the first and the initial stage of embryonic development that initiates the growth and development of the embryo from the parent cell.

Therefore, option 1. mitosis is the process of embryonic development.
