Ionic and covalent bonds help arrange atoms into unique structures for proteins like hemoglobin. Why is this necessary?(1 point)
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.

Explanation:
Hope this helps :\
A renewable resource is a substance of economic value which can be replenished or replaced either through natural recurring processes or biological reproduction.
This happens due to the renewable energy. Now let us understand the renewable energy are those energy that can be used again and again and it re-new after a short period of time. it is generally defined as that kind of energy resources that can be renewed naturally.
Renewable sources of energy can replace conventional sources of energy which produce harmful gasses which is harmful as well as costly.
We divide this energy in few sectors like: residential, commercial, transportation, and industrial. People use these resources for many different things which are used daily.
One of the major resource is the UV rays and people use it to produce the electricity. Many of such resources are also used in different chores like cooking, driving vehicles, etc.
Example: biomass is a biological material taken from plants or plant-based materials.
Biomass is considered a renewable resource because plants and plant-based materials can be found everywhere and once used these plants will continue to grow and supply the demand for biomass consumption.
Therefore, these resources are the most useful resources which can be renewed easily and thus used in different ways.

A net external force must be applied to get an object moving because an object at rest will remain at rest unless acted upon by a net external force.
What is newtons law ?Newton's laws of motion are three fundamental classical mechanics laws that describe the relationship between an object's motion and the forces acting on it. These laws are summarized as follows: Unless acted upon by a force, a body remains at rest or in motion at a constant speed in a straight line.
Balanced forces result in zero velocity; unbalanced forces result in constant velocity.
An acceleration of an object depends on the mass that allows it to unbalance a change in motion or a change in resting state.
Mass of an object is a measure of an object's inertia-the motion the mass, the force it is to change its motion.
Thus, To move an object, a net external force must be applied because an object at rest will remain at rest unless acted upon by a net external force.

Which fossil in the second simulation could be an index fossil? Make an evidence-based claim. 1.
In the first simulation, where can you infer that there may have been a mass extinction? Make an evidence-based claim. 2.
Answer: A valuable index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time.
Explanation:
An index fossil is any animal or plant preserved in the Earth's rock record that is characteristic of a particular span of geologic time or environment. A valuable index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short-range through time. Index fossils are the basis for defining boundaries in the geologic time scale and for the correlation of strata. In marine strata, index fossils that are commonly used include the single-celled Protista with hard body parts and larger forms such as ammonoids. In terrestrial sediments of the Cenozoic Era, which began about 65.5 million years ago, mammals are widely used to date deposits. These animal forms have hard body parts, such as shells, bones, and teeth, and evolved rapidly.
Answer:
Ammonites, trilobites and graptolites are often used as index fossils.
Mass extinction can be identified by traces in the fossil record. The strata corresponding to this time period contain a variety of life forms when compared to a younger layer. it can be inferred that mass extinction is a possibility.

Scientists are looking for ways to help increase the amount of calcium carbonate in oceans so that coral reefs can be healthy ecosystems again. Why is the amount of calcium carbonate in the ocean decreasing? (1 point)
Responses
Increased amounts of carbon dioxide cause reactions to happen in the water that decrease the pH and the amount of calcium carbonate.
Decreased amounts of carbon dioxide cause reactions to happen in the water that increase the pH and decrease the amount of calcium carbonate.
Increased amounts of carbon dioxide cause reactions to happen in the water that increase the pH and decrease the amount of calcium carbonate.
Decreased amounts of carbon dioxide cause reactions to happen in the water that decrease the pH and the amount of calcium carbonate.
Answer:
As ocean acidification increases, available carbonate ions (CO32-) bond with excess hydrogen, resulting in fewer carbonate ions available for calcifying organisms to build and maintain their shells, skeletons, and other calcium carbonate structures.Ocean acidification describes the lowering of seawater pH and carbonate saturation that result from increasing atmospheric CO2 concentrations. There are also indirect and potentially adverse biological and ecological consequences of the chemical changes taking place in the ocean now and as projected into the future.There are fewer carbonate ions available for calcifying organisms to construct and maintain their shells, skeletons, and other calcium carbonate structures as ocean acidification progress because more of the available carbonate ions (CO32-) link with more hydrogen.
Ocean acidification is the term used to describe the decrease of seawater pH and carbonate saturation brought on by rising CO2 levels in the atmosphere. Indirect and potentially harmful biological and ecological effects are also a result of the current and anticipated chemical changes in the ocean.

What can scientists use to determine the relative order of events on the geologic timescale?
Answer:
Scientists use a geologic time scale to illustrate the order in which events on Earth have happened.
Explanation:
Scientists can use the geologic time scale to determine the order in which several events on Earth have happened or taken place.
What is a geologic timescale?The geologic time scale can be described as a representation of time based on the rock record of Earth and is a system of chronological dating that uses chronostratigraphy and geochronology.
The geologic time scale can be used by scientists to observe changes in the fossils by examing the oldest to youngest sedimentary rocks or layer by layer.
The geologic timescale also used relative dating to divide Earth’s past into many layers of time and utilized absolute dating to know the actual number of years ago that specific occurrences took place.
Relative dating does not show any specific dates but it allows us to know if a fossil or stratigraphic layer is older than another while Absolute dating methods provide more specific origin dates and timelines.

a. solar radiation moves freely
b. open
c. closed
d. due to gravity matter cannot freely move
i dont know the subject help
Answer: D and it should be C or A I'm second guessing-
Explanation:
Because the Earth is round, the frigid polar regions never get a high sun, and because of the tilted axis of rotation, these areas receive no sun at all during part of the year. The Earth revolves around the sun in an elliptical orbit and is closer to the sun during part of the year. When the sun is nearer the Earth, the Earth's surface receives a little more solar energy. The Earth is nearer the sun when it is summer in the southern hemisphere and winter in the northern hemisphere.
Earth is described as an open system and due to gravity matter cannot move freely and the correct options are option B and D.
Earth can be described as an open system due to its interactions with its surroundings. It receives solar radiation from the sun, which provides energy to sustain various processes on Earth. This energy drives the Earth's climate, weather patterns, and the cycling of substances such as water, carbon, and nutrients. However, Earth is not a closed system because it exchanges matter with its surroundings.
For example, it gains meteorites and cosmic dust from space and loses gases, such as hydrogen and helium, from its upper atmosphere.
Additionally, Earth's gravity holds its atmosphere and prevents the escape of gases and most solid materials into space. Thus, Earth's system is characterized by the exchange of energy and matter within the constraints of gravity.

This simulation contains rock layers and fossils from several different locations. Arrange the rock layers in the correct order, from the oldest at the bottom to the youngest at the top. Once a fossil disappears, it’s gone from the fossil record and does not reappear.
ill give brainlist if your answer is correct.
Answer:
The arrangement of fossil in the earth helps one understand the age of the rock.
Explanation:
To arrange the rock layers correctly, begin with the oldest layer at the bottom and proceed to work chronologically up.
The rock strata and fossils in this simulation provide information about the Earth's geological history. The theory of superposition helps us explain why the oldest rock layers are at the bottom and the youngest layers are at the top. We can establish the relative ages of the rocks by studying the fossils within each stratum. Fossils from earlier strata are no longer detected as new layers form, indicating that they have vanished from the fossil record and will not resurface. We can learn about the properties of the rock strata and the fossils they contain by carefully investigating their characteristics. We can reconstruct the timeline of Earth's geological past, understanding the changes that occurred over time.

Soap is a weaker base than bleach and it has more hydronium ions than bleach. It lies closer to a neutral pH. Therefore, option (A) is correct.
What are acids and bases?An acid is capable of donating a proton to another substance and is generally identified by its sour taste. A base is capable to accept a hydrogen ion from acid and is characterized by a bitter taste and a slippery texture.
Acids can turn blue litmus paper into red while Bases can turn red litmus paper into blue. A base can dissolve in water and when bases chemically react with acids, yield salt, and water as products.
pH = -log [H⁺]
The pH value of the bases lies between 7 to 14. The more the pH value stronger will be the base. The concentration of hydronium ions will be less if the pH value is higher. Therefore, soap has less pH value so it has more hydronium ions.
