Ionic and covalent bonds help arrange atoms into unique structures for proteins like hemoglobin. Why is this necessary?(1 point)
Answers
Answer:
Ionic bonds can be important to protein structure because they are potent electrostatic attractions. In the hydrophobic interior of proteins, ionic bonds can even approach the strength of covalent bonds
Covalent bonds in amino acids are useful to stabilize the structure of the proteins and their interactions. The ionic bond formed as the atoms in amino acids with opposite charges accompanied strong electrostatic attractions.
What types of bonds are involved in protein structure?Proteins are 3D structures of amino acids that are further made of an amine and a carboxyl group, and are arranged in specific structures in four levels to give rise to the complete protein molecule.
Proteins can be described as the polymers of polypeptides which are structured by arrangements of these chains in a three-dimensional structure. They are folded and are driven by special non-covalent interactions such as peptide bonds, ionic bonds, hydrogen bonds, Van der Waals interaction, and disulfide bridges.
The primary structure is the sequence of amino acids through peptide bonds to form a polypeptide chain. The secondary structure is a sub-structures made by hydrogen bonding between the main chain peptide groups on the polypeptide backbone chain.
Tertiary structure is the 3D arrangement of protein in which α and β helices are folded into a globular structure with the interactions such as hydrogen bonds, salt bridges, disulfide bonds, and tight packing of side chains.

B. Desert canyons collect all water and funnel it out of the desert.
C. Desert lakes absorb all the water.
D. Mountains block the winds that bring rain clouds.
Answers
Answer:
As I'm Not % Sure I Can Say C & D don't seem Right, Leaving A & B Having Me to Think the Answer is A (Hope I'm Right Good-Luck)
Explanation:
Answer: Mountains block the winds that bring rain clouds.
Explanation: By acting as obstacles to the flow of air masses, mountains contribute significantly to the dryness of deserts. Orographic lifting is a process that occurs when moist air is forced to ascend as it approaches a mountain range. The moisture in the air condenses and forms clouds as the air cools as it climbs. As a result, on the windward side of the mountains, the air loses a lot of its moisture as precipitation. The air has already lost a significant amount of moisture by the time it reaches the leeward side of the mountains, creating a rain shadow effect. On the leeward side of the mountains, this impact results in a dryer area that is often a desert. Consequently, the existence of mountains influences

What happens to the atoms that make up hydrogen fuel as it burns?
Answers
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.

In the following images, a blue circle represents an atom of one type of element, and a red square represents an atom of a second type of element. Determine which of them represent a pure substance, a homogenous mixture, and a heterogeneous mixture.
Are these in the right order?
Answers
Answer: No they are not. "Pure substance" is supposed to be placed in the middle picture. "Homogenous mixture" is supposed to be placed in the right picture. "Heterogenous mixture" is supposed to be placed in the left picture.
Explanation:
Pure Substances:
There are two categories of pure substances: elements and compounds (In our case, we have a compound).
Element (e.g. the blue circles or the red squares):
An element is a fundamental substance.An element cannot become simpler than itself, even if chemical separation methods are used.Compound (e.g. the blue circles bonded together with the red squares in the middle picture):
A compound is a substance made of two or more elements in fixed proportions (i.e. One element has the same amount as the other).A compound can be made into individual elements or simpler substances using chemical methods of separation.Mixtures:
There are two categories of mixtures: homo- and hetero- genous.
Homogenous mixture:
The substances or elements are mixed to look like one single substance and cannot be told apart (e.g. When salt dissolves in water, the water still looks like water).The substances or elements are distributed evenly throughout the apparatus. The number of different types of substances or elements can vary (e.g. There is more water than salt) The substances or elements do not bond together.Heterogenous mixture:
The substances or elements are mixed and can be told apart (e.g. When oil is mixed with water, the oil is "water-hating" so it forms its own layer on the bottom, while the water forms another layer on top of the oil layer).The substances or elements are distributed where one type of substance or element is bunched up in one spot and another substance or element in another spot.The number of different types of substances or elements can vary.The substances or elements do not bond togetherThe second Image is not a homogenous mixture, it is a heterogenous mixture as two different types of elements are mixed together.
The mix of two different types of elements in the heterogenous mixture is not uniform and has uneven mixed types.
The third image is a homogenous mixture as even though two different types of elements are together, they are not mixed with each other.
Unlike in the heterogenous mixture, in a homogenous mixture, there is a uniform mix of two different types of elements.
The first image is correct, the image depicts a pure substance.

Answers
Answer:
d
Explanation:
a) Atom 1 has 35 protons and 45 neutrons, which means it is the element bromine (Br). Atom 2 has 12 protons and 12 neutrons, which means it is the element magnesium (Mg).
What is a metalloid?A metalloid is an element that acquires both metal and nonmetal properties. Metalloids have some characteristics of metals, such as being good conductors of electricity, while also having some nonmetallic properties such as being brittle and lacking the ability to be hammered into shape. They are located along the "staircase" on the periodic table, between the metals and nonmetals, and include elements such as boron, silicon, germanium, arsenic, antimony, and tellurium. Metalloids are important in various applications such as semiconductor industry, in which silicon is the most widely used metalloid for the production of computer chips and solar cells.
b) Bromine (Br) is a nonmetal and magnesium (Mg) is a metal.
c) Magnesium (Mg) is a metal and bromine (Br) is a nonmetal, so they would form an ionic bond.
d) The compound formed between magnesium (Mg) and bromine (Br) would be named magnesium bromide.
e) The formula for magnesium bromide is MgBr2, since magnesium (Mg) has a +2 charge and bromine (Br) has a -1 charge.
