Which of the following functional groups contains only carbon, hydrogen, and oxygen? A) carboxyl group B)amino group C)sulfhydryl group

Answers

Answer 1
A. carboxyl group

amino - is nitrogen containing
sullf - is sulfur containing
Answer 2

The functional group that only contains carbon, hydrogen, and oxygen is carboxyl group. The correct option is A.

What is a functional group?

Functional groups are groups of atoms in a substance that control the complex's chemical behavior include groupings like the hydroxyl group in an alcohol.

The functional group refers to the area of a substance that interacts with another component.

An atom or group of atoms known as a functional group is in charge of a certain chemical characteristic of an organic molecule.

Functional groups are a way to categorise organic molecules. An organic compound with a functional group has a different attribute from what it would otherwise have.

The two functional groups hydroxyl (single-bonded OH) and carbonyl (double-bonded O), which are both connected to one carbon atom, are combined to form carboxyl groups.

The amino group have nitrogen along with carbon, hydrogen, and oxygen, while sulfhydryl group have sulfur in addition.

Thus, the correct option is A.

Photographs of the surface of Mars reveal the presence of sand dunes that shift over time. These dunes demonstrate the presence of what phenomenon on Mars?
f Magnetic pole reversals
g Winds
h Plate tectonics
j Precipitation

Answers

the answer is g
hope this helps
Final answer:

The presence of shifting dunes on Mars is evidence of wind activity on the planet. Martian winds are capable of redistributing surface material and forming dunes, and the photographs of these dunes indicate active wind-driven processes.  So the correcct option is g.

Explanation:

The shifting dunes on Mars demonstrate the presence of winds on the planet. These winds play a crucial role in redistributing surface material. As described, much of the material stripped from Martian canyons has been deposited into extensive dune fields, primarily at high latitudes.

Mars experiences various wind-related phenomena, such as dust devils, which are responsible for creating patterns on the surface by moving dust and sand. These dust devils and windstorms have enough power to move sand and create dunes, which change shape and position over time. The passage of Martian winds over loose sediments can also result in cross-bedded sandstone formations, as have been interpreted from images taken by the Curiosity rover in Gale Crater, indicating past interactions with liquid water.

In summary, Mars' winds are integral to the planet's surface dynamics, creating and shifting the dunes observed in high-resolution photographs. These winds are an essential factor in understanding the Martian climate, surface erosion, and geological history.

Trees use narrow tubes to transport water upward. Which property of water allows the water to rise in these narrow tubes?

a.net charge of molecules
b.high boiling point
c.cohesion of molecules
d. high vapor pressure

Answers

Answer:

C. Cohesion of molecules

Explanation:

Cohesion is the interaction of molecules of the same substance together. By the force of cohesion if two drops of water come together they form one. Water has high rates of cohesion due to hydrogen bonds.  

This phenomenon also called surface tension and is what allows small insects to stand on water.

Cohesion along with adhesion of water to the walls of the narrow tube generate what is called capillarity. This allows liquids to ascend inside the narrow tubes. As long as the cohesion is less than the adhesion, the liquid will rise until both forces are equal.

what effect has breast cancer research had on society

Answers

Breast cancer research has no impact outside of a lab.

But today in my own opinion breast cancer has started movements and now more cancers are out here today and there are no cures, so people are now investing more money to scientists to find treatments, and also scientists now don't have the solution to everybody's problems and this is causing distress to people.

Final answer:

Breast cancer research has led to advancements in early detection, treatment, and awareness. It has improved survival rates, influenced societal attitudes, and addressed healthcare disparities.

Explanation:

Breast cancer research has had a significant impact on society. It has led to advancements in early detection methods, improved treatment options, and increased awareness about the disease. For example, research has contributed to the development of mammography and genetic testing, which help in the early detection of breast cancer. It has also led to the development of targeted therapies, such as Herceptin, that have improved the survival rates of patients with HER2-positive breast cancer (BCA, 2012).

Furthermore, breast cancer research has influenced societal attitudes and behaviors. Awareness campaigns, like the pink ribbon movement, have raised public consciousness about breast cancer and encouraged support, fundraising, and advocacy for the cause. Research has also highlighted the importance of addressing inequalities in access to healthcare, leading to efforts to reduce health disparities and improve the quality of care for all individuals.

What distinguishes one element from another

Answers

The number of protons in the atom of an element (is that confusing) corresponds with the atomic number of the element, say hydrogen (#1) would only have one proton.

(Well that's the simplest way)

The main factor that distinguishes one element from another is its atomic number.

Each element on the periodic table has a unique atomic number, which corresponds to the number of protons found in the nucleus of an atom of that element.

For example, hydrogen has an atomic number of 1 because it has one proton, while carbon has an atomic number of 6 because it has six protons.

Other properties that help distinguish elements from one another include their atomic mass (the total mass of protons, neutrons, and electrons in an atom), electron configuration (the arrangement of electrons in atomic orbitals), and physical properties such as melting point, boiling point, density, and color.

Thus, it is the atomic number that serves as the primary characteristic distinguishing one element from another.

Answers

Final answer:

An invasive species is a species that arrives in a habitat it had not previously occupied and establishes a population that spreads autonomously. It has specific needs or requirements to survive, grows rapidly and competes with other plants or animals, and produces large numbers of seeds/offspring at a young age. However, the characteristic that is NOT associated with invasive species is having a native region with a climate similar to the invaded area.

Explanation:

An invasive species is a species that arrives in a habitat it had not previously occupied and establishes a population that spreads autonomously. It has specific needs or requirements to survive, grows rapidly and competes with other plants or animals, and produces large numbers of seeds/offspring at a young age. However, the characteristic that is NOT associated with invasive species is having a native region with a climate similar to the invaded area.

Final answer:

Invasive species are adaptable and not characterized by having specific survival needs. They threaten biodiversity due to rapid growth and competitive advantages, but don't necessarily originate from areas with similar climates to the regions they invade.

Explanation:

The characteristic of an invasive species that is NOT true is that they have specific needs or requirements to survive. Invasive species are typically successful exactly because of their ability to thrive in a variety of conditions and do not have highly specific environmental requirements. These species are adaptable, grow rapidly, and often compete with native plants or animals, often causing conservation problems as they threaten biodiversity in invaded ecosystems. Their successful spread usually depends on their reproductive strategies, such as producing large numbers of seeds or offspring at a young age. Moreover, invasive species do not necessarily come from a native region with a climate similar to the affected invaded area; they often have broad environmental tolerances.

What is photosynthesis?

Green plants and certain other creatures convert light energy into chemical energy through a process called photosynthesis. Light energy is gathered and utilized during photosynthesis in green plants to change the water, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.

It is hard to overstate the role that photosynthesis plays in sustaining life on Earth. There might eventually be little food or other organic materials on Earth if photosynthesis stopped. The majority of life would vanish, and eventually, the atmosphere of Earth would contain almost no gaseous oxygen. Only chemosynthetic bacteria, which can use the chemical energy of certain inorganic substances and are not reliant on the conversion of light energy, would be able to survive in such an environment.

The fossil fuels (coal, oil, and gas) that drive modern society today were created by plants using energy from photosynthesis carried out millions of years ago. Green plants and tiny critters that fed on plants grew more rapidly in the past than they were eaten, and as a result, sedimentation and other geological processes buried their remnants in the Earth's crust. These organic residues were gradually transformed into fossil fuels there, shielded from oxidation.

Therefore, the two measurements taken here are the size of the bubbles and their rate of production.

Final answer:

Scientists must always endeavor to avoid biases in their experiments. Biases can impede the objectivity of the scientist and the validity of the experiment's results.

Explanation:

A scientist must always try to avoid biases in scientific experiments. A bias is a prejudice in favor of or against one thing, person, or group compared with another, usually in a way that's considered to be unfair. Biases can affect the objectivity of the scientist and the credibility of the experiment. For example, if a scientist is testing a new drug and they unconsciously favor positive results because they want the drug to succeed, that can introduce bias into the process, skewing the results. This is why it's crucial for scientists to recognize and mitigate biases when conducting research.

Explain how the amount of direct sunlight hitting a location near the equator would be different than a location near to one of the poles

Answers

Places located near the equator receives more sunlight than those located near one of the poles. This has something to do with the angle and how the sun casts its light. The more that you are at the center, the more direct the sunlight is shining on you. As you go further from the center, the angle of sunlight bends, giving an uneven distribution of sunlight to areas far from the equator. This is why most countries that are located far from the equator experience snow. They receive less sunlight than those who are living in tropical countries.
