Answer:
Explanation:
Molecule is the general term used to describe any atoms that are connected by chemical bonds. Every combination of atoms is a molecule. A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds.
Atoms are the building blocks of molecules. A molecule is formed when two or more atoms chemically bond together.
What are they made up of?Atoms consist of a nucleus containing protons and neutrons, surrounded by electrons in energy levels or orbitals. When atoms combine, they share, donate, or accept electrons to achieve a stable electron configuration, forming chemical bonds.
These bonds can be covalent, where atoms share electrons, or ionic, where electrons are transferred between atoms. The arrangement and types of atoms in a molecule determine its chemical properties and behavior. Thus, molecules are composed of specific combinations of atoms held together by chemical bonds.

Give an example of haploid and diploid.Thanks
Answer:
Explanation:
In the higher organism, such as humans, haploid cells are only used for sex cells. In the higher organism, such as humans, all other cells beside sex cells are diploid. Examples of haploid cells are gametes (male or female germ cells). Examples of diploid cells include blood cells, skin cells and muscle cells.
Answer:
Haploid: Haploid cells contain a single set of chromosomes. Gametes are an example of haploid cells produced as a result of meiosis. Examples of gametes are the male and female reproductive cells, the sperm and egg cells respectively.
Diploid: Diploid cells, or somatic cells, contain two complete copies of each chromosome within the cell nucleus. The two copies of one chromosome pair up and are called homologous chromosomes. Examples of diploid cells include skin cells and muscle cells.

What term describes an allele that is masked or covered/dominated up by another allele?
A. Recessive Allele
B. Dominant Allele
C. Homzygous
D. Heterozygous
Answer:
B dominant allele
Explanation:
B is the correct answer, I just took the test
Mark Branliest PLEASE
Answer:
A.
Explanation:
A recessive allele is an allele that gets covered up by a dominant allele.
Example -
Lets say that two people were breeding. Brown hair would be the dominant trait, with blonde as a recessive. If the male has the allele Bb, and the female has bb, then you would put these into a table. Your outcome would come as
B b
b Bb bb
b Bb bb
So there would be a 50/50 chance of the offspring having brunette or blonde hair.

Give an example of how animals play a part in the carbon cycle.
Answer:
Organisms play an important role in the carbon cycle in the following ways: Animals obtain their carbon by eating plants; they release carbon in respiration. ... Micrororganisms (such as fungi and bacteria) return carbon to the environment when they decompose dead plants and animals.
Explanation:
The theory of evolution is controversial among some people, but not among scientists. Lots and lots of evidence support this theory. Some of the strongest evidence comes from the fossils of other hominids - human-like skulls, for example, have been found on many continents, revealing that we didn't always look the way we look now. We can also see why we evolved the way we did. For instance, humans (and other great apes) didn't grow thumbs because we thought they'd make it easier to pick things up. Instead, a series of likely hundreds of slight mutations moved the thumb to its current place because those animals with opposable thumbs were better able to survive and reproduce. That's what evolution is all about: tiny changes in organisms of a species over a huge amount of time.
Which of these would provide the best evidence for the theory of evolution?
A
fossils of ancient tigers that had larger ears than tigers have today
B
oil found deep under the ice sheets of Antarctica
C
a person’s hair growing faster in the summer than it does in winter
D
ancient maps that show that countries had different borders long ago
The following would provide the best evidence for the theory of evolution: fossils of ancient tigers that had larger ears than tigers have today, which are present in Option a.
What is evolution?The best evidence for the theory of evolution would be fossils of ancient species that show significant differences from modern species, as these fossils can provide direct evidence of the process of evolution. For example, if there were fossils of ancient tigers that had larger ears than modern tigers, this would suggest that the size and shape of the ears of tigers have evolved over time, likely due to some selective pressures such as environmental changes, predator-prey interactions, or sexual selection.
Hence, the correct answer is fossils of ancient tigers that had larger ears than tigers have today, which are present in Option a.

Choose one region on the world map. How does the climate their differ during El Niño and La Niña?
Answer:What are El Niño and La Niña?
El Niño and La Niña are opposite phases of a natural climate pattern across the tropical Pacific Ocean that swings back and forth every 3-7 years on average. Together, they are called ENSO (pronounced “en-so”), which is short for El Niño-Southern Oscillation.
The ENSO pattern in the tropical Pacific can be in one of three states: El Niño, Neutral, or La Niña. El Niño (the warm phase) and La Niña (the cool phase) lead to significant differences from the average ocean temperatures, winds, surface pressure, and rainfall across parts of the tropical Pacific. Neutral indicates that conditions are near their long-term average.
Maps of sea surface temperature anomaly in the Pacific Ocean during a strong La Niña (top, December 1988) and El Niño (bottom, December 1997). Maps by NOAA Climate.gov, based on data provided by NOAA View. large versions La Niña | El Niño
What happens during El Niño and La Niña?
During El Niño, the surface winds across the entire tropical Pacific are weaker than usual. Ocean temperatures in the central and eastern tropical Pacific Ocean are warmer than average, and rainfall is below average over Indonesia and above average over the central or eastern Pacific.
Rising air motion (which is linked to storms and rainfall) increases over the central or eastern Pacific, and surface pressure there tends to be lower than average. Meanwhile, an increase in sinking air motion over Indonesia leads to higher surface pressure and dryness.

Generalized Walker Circulation (December-February) anomaly during El Niño events, overlaid on map of average sea surface temperature anomalies. Anomalous ocean warming in the central and eastern Pacific (orange) help to shift a rising branch of the Walker Circulation to east of 180°, while sinking branches shift to over the Maritime continent and northern South America. NOAA Climate.gov drawing by Fiona Martin.
During La Niña, it’s the opposite. The surface winds across the entire tropical Pacific are stronger than usual, and most of the tropical Pacific Ocean is cooler than average. Rainfall increases over Indonesia (where waters remain warm) and decreases over the central tropical Pacific (which is cool). Over Indonesia, there is more rising air motion and lower surface pressure. There is more sinking air motion over the cooler waters of the central and eastern Pacific.

Generalized Walker Circulation (December-February) anomaly during La Niña events, overlaid on map of average sea surface temperature anomalies. Anomalous ocean cooling (blue-green) in the central and eastern Pacific Ocean and warming over the western Pacific Ocean enhance the rising branch of the Walker circulation over the Maritime Continent and the sinking branch over the eastern Pacific Ocean. Enhanced rising motion is also observed over northern South America, while anomalous sinking motion is found over eastern Africa. NOAA Climate.gov drawing by Fiona Martin.
Between the warm phase (El Niño) and cool phase (La Niña), scientists describe conditions as “ENSO-neutral.” Neutral means that the temperatures, winds, convection (rising air), and rainfall across the tropical Pacific are near their long-term averages.

Is glucose, C6 H12 O6, an organic or inorganic compound? How can you tell?
Glucose ([tex]C_6H_1_2O_6[/tex]) is definitely an organic compound. This is because it is made of atoms of carbon and hydrogen along with oxygen.
What are organic compounds?Organic compounds may be characterized as those large classes of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.
According to the context of this question, Glucose is a simple sugar that living cells definitely utilize for energy and accomplishment of their metabolic activities.
According to biochemistry, any natural molecule that consists of carbon and hydrogen atoms is considered organic. So, Glucose is also made up of carbon, hydrogen, and oxygen atoms, and hence it is an organic compound.
Therefore, Glucose ([tex]C_6H_1_2O_6[/tex]) is definitely an organic compound. This is because it is made of atoms of carbon and hydrogen along with oxygen.

Changes to an environment, such as drought or human activity, can reduce the available resources. What do you predict might happen if resources were to become reduced or unavailable?
Answer:
Animals and Human may die
Explanation:
If your talking about natural resources etc trees which give oxygen might not be here (The oxygen will still be in the air for awhile, but it may run out) Animals and us humans may suffocate or starve. Than we have the plants which we use for food or medicine. They wouldn't be here either and we wouldn't be able to take care of ourselves safely and go unharmed.
A person's basic material necessities for a happy existence, health, positive social relationships, security, and their freedom of choice and action are all impacted by changes to ecosystem services.
What are resources?A resource is an element or component of the environment that an organism needs for healthy development, maintenance, and reproduction in biology and ecology.
One organism's consumption of resources may make them unavailable to other organisms.
Human welfare and ecosystem services have a nonlinear relationship. A marginal increase in environmental services often makes only a small positive impact on human well-being when supply is abundant compared to demand.
However, a little reduction in the service's availability can have a significant negative impact on people's well-being.
Similar to trees, plants provide us with food and the oxygen we breathe; if they disappeared, people and other animals would go hungry and perish.
Thus, this may happen if resources were to become reduced or unavailable.
