How are atoms and molecules related?
Answers
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.

B- Deposition uses the small particles in the soil to create rocks.
C- Precipitation causes soil to stick together and form rocks.
D- Erosion takes away parts of the rocks that are not useful to the soil.
Answers
Weathering breaks off small pieces of rock that become part of the soil.
What are High plains?
The High Plains is a region in the United States that includes the southern Great Plains and, more specifically, the northern Llano Estacado.
The northernmost Panhandle of Texas, northeastern New Mexico, eastern Colorado, and westernmost Kansas might all be considered parts of the High Plains in the latter meaning.
The Platte, Arkansas, and Canadian rivers drain the high plains, which are typically flat grasslands. Cattle, irrigated and dry farming, as well as some natural gas and petroleum extraction, form the foundation of the economy.
Therefore, Weathering breaks off small pieces of rock that become part of the soil.

Which environment will experience the LEAST amount of change over time?
A. an ecosystem with a climax community
B. an ecosystem that is in secondary succession
C. an ecosystem that is in primary succession
D. an ecosystem with only pioneer species
Answers
Answer: D
Explanation: the pioneer species is the first species to live in an environment
An ecosystem with a climax community will experience the least amount of change over time. Therefore, option A is correct.
Why climax community ecosystem experience the least amount of change?A climax community is a stable community of plants and animals that has reached a state of equilibrium with its environment. In such a community, the number of species and their relative abundance tend to remain relatively constant over time, barring any major disturbances such as fire or human intervention.
In contrast, ecosystems in primary and secondary succession are undergoing significant changes as they transition from bare rock or disturbed land to a stable, self-sustaining community. Ecosystems with only pioneer species may also experience significant changes over time as more complex plant and animal communities develop.
Therefore, option A is correct.

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.

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

D

Answers
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?
Answers
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.
