What is the levels of kinetic energy in the particles in each state of matter
SSSSS [86.1K]

Solids, liquids, gases, and plasmas: these words should be quite familiar to you because they are the four phases of matter, which are simply the different forms matter can take on. What's neat is that many substances can exist as more than one phase. Take water, for example: water can exist as a solid (ice), a liquid (liquid water), and a gas (water vapor).

The difference between these states is the amount of energy. Solids have the least amount of energy, which is part of why their particles hang so tightly together. Liquids have more energy than solids, which is why they will take on the shape of their container but only up to the surface.

Gases have even more energy than liquids. So much more in fact that their particles spread out to fill the entire space of their container. Gas particles have so much energy that they just can't keep still. They fly around in all directions, putting as much distance as possible between themselves and the rest of the gas particles.

Plasmas are ionized gases, and in their natural form are uncommon on Earth. You've seen them as man-made things, like neon signs and fluorescent light bulbs. But in the rest of the universe, plasma is actually the most common phase of matter! Most stars are plasma, as are the northern lights you see around the Polar Regions. Plasma only exists under certain conditions though, so we'll end our discussion of it here for this lesson.

The presence of paired chromosomes makes a diploid/germ/haploid/gamete cell, while a single member of a pair of chromosomes make
geniusboy [140]
The presence of paired chromosomes makes a <u>diploid </u>cell, while a single member of a pair of chromosomes makes a<u>haploid </u>cell.

Diploid cells. Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number. </span>

Scientists often classify organisms based on their ability to perform certain processes
Mrac [35]

A. Plants can make their own food using energy from the Sun.

Animals cannot make their own food.

Explanation:

An example of the physiological capabilities of plants is their ability to make food on their own using the energy from the sun and chemical substances in the environment, animals do not make their own food.

  • Physicological ability refers the body functions of an organism. It refers to the life biochemical processes a body is able to carry out based on its design.
  • Metabolism is a living function attributable to all life.
  • Organisms can either build up energy such as seen in plants during photosynthesis. This process is called anabolism.
  • Some other organisms, makes use of the energy in their own life process and this is a catabolic process.
