Answer:      When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.

Explanation:

hopes this helps

The electron can come back down to the lower energy shell releasing heat and light energy seen as bioluminescence.

According to the Bohr theory, atoms absorb energy and move from a lower to a higher energy level. The energy absorbed during this transition is equal to the difference in energy between the two levels.

This innermost shell is called the ground state of the atom while the higher energy level is called the excited state. Since atoms are unstable in the excited state, the atom quickly returns to the ground state, emitting energy in the form of heat and light in the process.

Both the chloroplast and the mitochondrion are organelles found in the cells of plants, but only mitochondria are found in animal cells. The function of chloroplasts and mitochondria is to generate energy for the cells in which they live. The structure of both organelle types includes an inner and an outer membrane

Answer:

This approach is a technique used to appraise the environmental impact associated with all stages of a product's life. (from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal-recycling).

Explanation:

Everything that  is produced goes through these five main stages:

1.) material extraction

2.) manufacturing

3.) packaging

4.) transportation

5.) use and end of life

At each of these stages, there are inputs and outputs, flow-throughs, value losses, and potential gains.

Answer:

Dogs and dolphins have a lot in common. Even though these animals may be from different species, and live in entirely different environments, they do share one commonality: they're friendly and curious. Both dogs and dolphins will be the first to investigate a new person or situation

Explanation:

The dolphin fin is similar to a dog's leg in the following ways: Both are used for movement.

The dolphin fin helps the dolphin to swim and navigate in water, while the dog's leg is used for walking and running. Both are composed of bone and muscle. The dolphin fin has a skeletal structure made up of bones and muscles, which allow it to move in different directions. The dog's leg also has a skeletal structure made up of bones and muscles, which allow it to support the dog's weight and move in different directions.

Both are adapted to their respective environments. The dolphin's fin is shaped to help it move quickly and efficiently through water. The dog's leg is adapted to help it run and navigate on land. Both have joints. The dolphin fin has a joint where it connects to the body, which allows it to move in different directions. The dog's leg has joints that allow it to bend and move in different directions.

Answer:

Cytolysis does not occur under normal conditions in plant cells because plant cells have a strong cell wall that contains the osmotic pressure, or turgor pressure, that would otherwise cause cytolysis to occur.

Explanation:

:)

Answer:

Plants have a natural defense mechanism against cytolysis because they contain a tough cell wall. When a plant cell is placed in a hypotonic environment and water rushes in, the cell wall exerts an opposing pressure on the cell membrane, preventing it from expanding or rupturing. i hope this helps

Explanation:

Answer:

Dalton's experiments on gases led to his discovery that the total pressure of a mixture of gases amounted to the sum of the partial pressures that each individual gas exerted while occupying the same space. In 1803 this scientific principle officially came to be known as Dalton's Law of Partial Pressures.

Answer:

it needs energy to do mechanical work and respond quickly

Answer:

Water, organic molecules, and inorganic ions are the constituents of cells. Water constitutes the greatest fraction of the three, accounting for almost three-quarters of the total mass of a cell. The interactions between the various components of a cell and its water content is key to biological chemistry.

Sodium, potassium, magnesium, calcium, phosphate, and chloride, are among the chief inorganic ions of a cell, and represent not more than 1% of the cell mass. But the organic molecules are the really novel components of a cell. Most such organic compounds belong to one of the following molecule classes:

Carbohydrates

Lipids

Nucleic acids

Proteins

Within individual cells, there exist thousands of different types of macromolecules, or organic compounds. These will be different, even among the cells of the same person. The variations are more extensive among different people. Macromolecules - proteins, nucleic acids, and polysaccharides - are formed by the polymerization of hundreds of their low-molecular-weight precursors - amino acids, nucleotides, and simple sugars.

The diversity among macromolecules evolves from the vast potential to form different combinations of the 50 or so common monomers which make up a macromolecule. These macromolecules may constitute up to 90% of a cell’s dry weight. It is possible to comprehend the basic chemistry of a cell’s makeup by understanding the functions and structures of the four major types of organic compounds, or macromolecules.  

Carbohydrates

Carbohydrates are the basic building materials and nutrients of the body. Simple sugars and polysaccharides compose this group. Glucose is an example of a simple sugar that is an important cellular nutrient. Decomposition of the simple sugars by chemical reaction generates cellular energy as well as initiating the synthesis of other constituents of a cell. The polysaccharides, or complex carbohydrates, represent the form that sugar takes when it is stored. Polysaccharides are the structural components of a cell. Moreover, polysaccharides and other sugars may function as markers for certain cellular recognition processes, including the intracellular movement of proteins.

Lipids

Lipids are hydrophobic molecules. They are a highly efficient form of energy storage, and are major constituents of the cell membrane. They are important in cell signaling, function as the starting point for various biosynthetic processes such as the synthesis of estrogen and testosterone. Some lipids are able to convey signals from cell surface receptors to targets in the same or other cells. Phospholipids contain two fatty acids joined to a polar head group. Besides the phospholipids, cells have glycolipids and cholesterol.

Nucleic acids

Nucleic acids store and transmit hereditary data. DNA and RNA represent the informational molecules of a cell. DNA plays a crucial role as the genetic material of humans and many other species. RNA takes part in various cellular activities. Messenger RNA (mRNA) transports information from DNA to the ribosomes, where they are involved in synthesizing proteins. In addition, ribosomal RNA and transfer RNA are involved in protein synthesis. Other RNA molecules process and move both proteins and RNA. RNA can also catalyze chemical reactions, such as those involving the synthesis of proteins and the processing of RNA.

Proteins

Proteins play an important role in most of the tasks that an organism performs. Proteins carry out the work of a cell, directed by the genetic information carried by the nucleic acids. A cell holds many thousands of proteins, which function as a cell’s structural elements, storing and transporting small molecules, transmitting data among cells, and defending the body against the onset of infections. But proteins also function as enzymes that accelerate most chemical reactions. In this manner, proteins guide most cellular activities.
