What element is common to all macromolecules
Answer:
The four main classes of organic compounds (carbohydrates, lipids, proteins, and nucleic acids) that are essential to the proper functioning of all living things are known as polymers or macromolecules. All of these compounds are built primarily of carbon, hydrogen, and oxygen but in different ratios
Carbon is the common element in all the macromolecules.
• The four prime classes of macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
• All the macromolecules comprise atoms of carbon as their main structural components. The carbon is an atom that possesses the tendency to bond with all the four other atoms.
• The biological macromolecules comprise carbon in the form of chain or ring.
• The majority of the macromolecules are formed of single subunits or building blocks known as monomers.
• All the four macromolecules exhibit atoms of carbon. It is the fundamental constituent of all these macromolecules.
• Carbon is a versatile element that functions to act as the fundamental structural constituent or backbone of the macromolecules.
Thus, it is the carbon, which is the common element found in all the macromolecules.

Which property allows water to resist changes in temperature?
a) high specific heat
b) cohesion
c) adhesion
d) polarity
The property that allows water to resist changes in temperature is its high specific heat (Option a is correct).
Specific heat refers to the amount of heat that one substance needs absorb or lose to change (either rise or decrease) its temperature by one (1) degree Celsius (°C).The high heat capacity of the water is due to the hydrogen bonds among H2O molecules.When heat is absorbed, these hydrogen bonds are broken down and then H2O molecules move freely.In conclusion, the property that allows water molecules TO RESIST CHANGES in temperature is its high specific heat (Option a is correct).

What is diffusion and how does it work? What is osmosis and how does it work?
Answer:
Diffusion is the net movement of anything from a region of higher concentration to a region of lower concentration. Diffusion is driven by a gradient in concentration. The concept of diffusion is widely used in many fields, including physics, chemistry, biology, sociology, economics, and finance
Explanation:
Osmosis is the movement of water through a semipermeable membrane according to the concentration gradient of water across the membrane, which is inversely proportional to the concentration of solutes. ... The semipermeable membrane limits the diffusion of solutes in the water

can someone please help!!
Answer:
either B. or D. but i think its B.
Explanation:
Answer:
B.
Explanation:
The passage specifically mentions that "In natural condition,'' with this information we can use the process of elimination.
A is incorrect, how can humans genetically engineer an animal that has been in the wild its whole life.
C. is incorrect, the shape of this dog, nay any animal can not change in one generation. If this had happened the dog would be considered having a disability.
D. is incorrect, again how could humans interfere and breed dogs if they have not had any human contact. unless they cross bread, which is very unlikely, due to the descendants of this specific breed, and their location in the globe.
with all of this information it is safe to assume that option B is correct; most likely the ancestors of this dog became used to not running and easily finding food so the dog had a beneficial mutation, where it got rid of a body part it did not need, like long legs, but kept or enhanced things it needed like a long nose.

The map shows the distribution of wild boars in the United States (shaded area).
A map of the United notes showing the distribution of wild boars in dark orange. Wild boars appear most often in Texas, California, and Florida, and along the southern notes.
Which of these facts about wild boars is best supported by the evidence provided?
Wild boars were brought to the United States by humans.
Wild boars have quickly spread through the United States.
Wild boars have established successfully mostly in areas with warm climates.
Wild boars have a high reproductive rate and no natural predators.
Answer:
Regarding wild boar, the fact that is best supported by the evidence provided is wild boars have established successfully mostly in areas with warm climates.
Explanation:
The wild boar (Sus scrofa) is a mammal from Africa, whose capacity to adapt to the environment is high. However, it is usually found in warm climates where it has a good supply of water and food.
According to the description of its distribution on the map, the states where it is found —predominantly Texas, California and Florida— verify the fact that they can be found mostly in warm climates, where they have found an ideal environment for their development..

Which pair of Earth's sphere's interact the most when ocean waves break onto a beach?
-atmosphere and biosphere
-geosphere and atmosphere
-hydrosphere and biosphere
-geosphere and hydrosphere
Answer: geosphere and hydrosphere
Explanation:
The pair of Earth's sphere's interact the most when ocean waves break onto a beach are the geosphere and hydrosphere.
The geosphere includes the landforms, minerals, rocks, and every other process which gives the surface of the Earth its shape.
The hydrosphere is the part of the Earth's sphere which consists of water. It is made up of underground water, water on the Earth's surface and also the water that is in the air.
Why is the boundary between two air masses called a front
Answer:
The boundary between two air masses with different temperatures and different property is called front.
Explanation:
The boundary between two air masses is regarded as a weather front. Weather fronts can be either warm or cold fronts. The characteristics either side of a front would display the characteristics you’ve listed. So typically, if you considered an air mass ahead of a warm front which could be a polar maritime, this would be cold air so would have high density, and because it’s cold it’s ability to hold water (humidity) would be low. Conversely the air mass behind the warm front could be a tropical maritime air mass. So it would be warm, less dense and very humid.
A weather front is the line separating two air masses when they come together. The two air masses at a front have different densities depending on temperature and are difficult to mix.
What is front?A front is the line separating two adjacent air masses that is clearly delineated by their unique features. The two air masses should be distinct in terms of density, pressure, and temperature, and they should have come from sources that are located in latitudes that are apart.
The characteristics of the air mass that is replacing the previous air mass are used to identify fronts.
Therefore, the boundary between two air masses called a front, a cold front, is the boundary between two air masses traveling in opposite directions.

Consider these scenarios. Scenario A: Carmen reads an article in Tasty Food magazine stating that eating an apple can help you feel awake and alert. Scenario B: Yuki reads an article in the Professional Journal of Medicine stating that ginger root can help prevent some types of cancer. Which article is more likely to have been peer reviewed? How do you know?
Answer: The article read by Yuki is more likely to have been peer-reviewed because this article is part of a Journal Medicine and peer-review is mandatory in most Academic journals before publication.
Explanation:
Peer-review implies academic works such as research papers or articles are verified by peers of the author. For example, a medical article is evaluated by other experts in the same field with similar knowledge and competences. This process is essential to guarantee the information is accurate and reliable. Moreover, peer-review is used mainly in academic journals or academic papers. Indeed, most academic journals require new articles or papers to be peer-review before these are published in the journal.
In this context, it is likely the article red by Yuki has been peer-reviewed because this is part of a Medicine journal and it is a general standard for articles in journals to be reviewed. Also, this is not a requirement for articles published in regular magazines such as Tasty Food magazine.
