Name two ways that living things use proteins

Answers

Answer 1
Answer:

Proteins catalyze reactions, part of the immune system, transport molecules such as oxygen, and transmit messages from cell to cell.

What is protein?

Proteins are very large molecules made of basic units known as aminoacids. Proteins consist of carbon (C), hydrogen (H), nitrogen (N), oxygen (O), and sulfur (S).

Protein molecules are produced by twisted and folded strands of amino acids. Proteins are actively involved in the most important as well as basic aspects of life. These include metabolism, cellular communication, movement, molecular recognition, and defense.

The shape of structural proteins allows them to form essential structures of the body. Collagen holds most of the body tissues together, a protein with a fiber shape. Structural protein Keratin creates a network of waterproof fibers on the outer layer of the skin.

The shape of functional proteins enables them to contribute to the chemical processes of the body. Functional proteins include cell membrane receptors, hormones, growth factors, and enzymes.

How does the absorption and release of energy affect temperature change during a chemical reaction?  PLEASE HELP!!!!!!!!!!!!!!!

Answers

heat is a form of energy. if the system absorbs heat/ energy it is endo thermic if it releases heat or energy it is eothermic

Answer:

Heat is a form of energy. BUT if the system absorbs heat/energy it is endothermic if it releases heat or energy it is exothermic.

What types of atoms form cations

Answers

Cations are formed when atoms lose electrons, resulting in a net positive charge.

Generally, cations are formed by atoms of metals. Metals tend to have relatively low ionization energies, allowing them to easily lose electrons and form positively charged cations. Examples of metals that commonly form cations include sodium (Na⁺), calcium (Ca²⁺), iron (Fe²⁺ or Fe³⁺), and aluminum (Al³⁺), among others. It is important to note that not all metals form cations, as some metals can exhibit variable oxidation states or form anions in certain compounds.

Hence, Cations are formed when atoms lose electrons.

positively charged atoms

Explanation:

Scientists predicted Adamantium would have an Atomic radius of 327 pm. Once the element was measured experimentally, they found that the atomic radius was really 312 pm. Calculate the percent error of their prediction

Answers

The actual atomic radius of Adamantium is 327pm. The experimentally estimated value of atomic radius of adamantium is 312pm. The percent error can be calculated as,

Percent error = (actual value-estimated value)/actual value *100

                       = 327-312/327*100

=Approx. 5 percent error in their prediction.

what would happen if the cell wall in a plant cell just broke like all of them at the same time would it change the color or will it grow faster or will it die what will hapen

Answers

It would not change the color and it would not grow anymore. The cell wall is the outside layer of a plant, so if it eventually breaks off for some reason, it cannot grow anymore. Some plants can survive if their cell wall broke off, like a cactus. Cactuses can keep growing because it can be tall or short. (if someone like cut it in half or something, the cactus can still grow) Cactus does not have any leaves or anything connected to it (except for thorns) and if you break it, it can still grow.

Answer:

the cell will either
