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.

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.

Answer: Earth's shadow extends about 870,000 miles (1.4 million km) into space

Explanation:Like all shadows, the shadow of Earth is always opposite the sun. So you'll want to look eastward after sunset for the shadow (or westward before sunrise). Earth's shadow is the dark blue line above the horizon in this photo by Jörgen Andersson in Sweden. View larger.

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.

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.

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.

Answer:

1) transport process, 2) removing waste, 3) reproduction, 4) produce energy

Answer: the core of the earth heats up the more dense part of the mantle making it less dense. When the less dense part of the mantle rises, the more dense part of the mantle falls, and cools off. This motion continues creating convection currents

Answer:

A. Crab

Explanation:

The animals which are most likely to have an open circulatory system belongs to the Arthropoda Phylum of the animal kingdom. Crab belongs to this phylum. Thus, the correct option is A.

Arthropoda is the phylum of the animal kingdom. It consists of all the invertebrate animals which have an exoskeleton, a segmented body, and paired jointed appendages. It is the largest phylum of the animal kingdom.

The distinguishing characteristics of arthropods are their jointed limbs and cuticle made of chitin, and often mineralized with calcium carbonate.

Arthropods have an open circulatory system, it means the blood does not circulate in closed blood vessels however it is pumped into a cavity called a hemocoel. The blood is also known as hemolymph as it mixes with the other interstitial fluids.

Therefore, the correct option is A.

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.

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.

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.
