Most enzymes are proteins. Many cells make and use an enzyme called catalase to facilitate the decomposition of hydrogen peroxide (H2O2). The products of the decomposition are hydrogen (H2) and oxygen (O2). Stephanie is investigating the structure and function of catalase, and she is comparing catalase to other proteins. What can Stephanie predict will distinguish the structure of catalase from the structures of the other proteins she is studying? A. many regions made entirely of hydrogen and oxygen B. the chemical properties of the peptide bonds C. the types of amino acids it contains D. the sequence of amino acids it contains
Answer:
The correct answer is - B. the chemical properties of the peptide bonds.
Explanation:
The difference between the structures of catalase from other proteins depends on the chemical properties of the peptide bonds present in between the amino acids which decide the pH and temperature by their disruption. These bonds present between two alpha-amino acids when carboxyl of one amino acid interacts with the amino group of the other to form an amide-type covalent bond.

Which chemical is released by (2) WBC's that produces a non-specific inflammatory response?
Answer:
cytokines
Explanation:
Non-specific immune responses are integral to host cellular defense mechanisms. It is a general response, mediated by white blood cells, where cells rapidly react to pathogenic infiltration.
Here receptors on cells recognise molecules shared by a broad spectrum of pathogens, or even react to signals from damaged, injured or stressed cells like inflammatory cytokines in a cytokine storm.

Write about an experience, either real or imaginary using these words chemical energy, electric energy, kinetic energy, mechanical energy, nuclear energy, potential energy, radiant energy, seismic energy, sound energy, and thermal energy
Answer:
I stopped to think for a moment, and realized chemical energy is found in food. Then, I thought about how the other day when I saw lightning, that is an example of electric energy. Then I thought about how when throw a ball, that is a form of kinetic energy. The other day, when I was hammering a nail into a piece of wood, that was a form of mechanical energy. An example of nuclear energy would be the nuclear power plant by our house. Before my book fell off my table, this is an example of potential energy. The energy from the sun is an example of radiant energy. Volcanoes and earthquakes around the world are an example of seismic energy. Sound energy would be the balloon that I popped the other day. Thermal energy would be the heat I feel from the heater.

Which procedure will determine if water temperature affects the weathering of sedimentary rocks?
A. Test 3 identical sedimentary rocks, 1 each in 3 different water temperatures.
B. Test 3 identical sedimentary rocks in 1 water temperature.
C. Test 1 crushed sedimentary rock and 1 whole sedimentary rock in water.
D. Test 3 identical sedimentary rocks, 1 each in acid, 1 in a base, and 1 in water.
Answer:
The correct option is A
Explanation:
To determine if water temperature has an effect on weathering of sedimentary rocks, different number (perhaps three) of identical sedimentary rocks should be obtained and then individually placed in different water temperatures (with at least one of the "water volumes" used for each having a temperature close to the room temperature so as to be used as the control).
Thus, each of the identical sedimentary rock can be broken into three and placed individually; as in one part of the rock in 20 °C of water (control), another part of the rock in 40 °C and another in 60 °C of water.
This above procedure should be repeated for the remaining two other identical sedimentary rock to confirm if there is any effect.

What is RNA ?
What is replication?
Answer:
ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.
Explanatioim smart now give brainliest plz
Answer:
Ribose, found in RNA, is a "normal" sugar, with one oxygen atom attached to each carbon atom. Deoxyribose, found in DNA, is a modified sugar, lacking one oxygen atom (hence the name "deoxy"). In ribose, carbon atom #2 carries one hydroxyl group (colored red).
RNA is a ribonucleic acid, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule.Explanation:
