Answer:
Atoms are the basic units comprising matter, and interact in a variety of ways.
Explanation
The most fundamental unit of matter that makes up elements is called atoms. Atoms comprise nucleus-orbiting electrons- while protons and nuetrons make up a stable nuclues. Here, the neutrons are uncharged, while the negatively charged electrons are attracted to the positively charged protons at the atom's center
The number of protons the atom determines its atomic number, and the sum of protons and neutrons determine the atomic mass.
Elements in the periodic table, are typically represented by chemical symbols- abbreviations of their atomic name. They are arranged in order of valency- atoms in the same group typically have the same number f electrons on their valence shells, and thus their physical properties behave similarly (conductivity, melting points, boiling points).
Valence electrons, on outer valence shells, also influence bonding. The atoms donate, accept or share valence electrons in order to achieve more stable atoms. Bonding between elements form molecules, that may interact with molecules to form compounds.

What function are stomach cells adapted for
Answer:
The stomach is J-shaped and it can expand to temporarily store food. Partial digestion of the food takes place here. The churning action of the stomach muscles physically breaks down the food. The stomach releases acids and enzymes for the chemical breakdown of food.

In the light-I defendant reactions of photosynthesis
Answer: HOPE THIS HELPS!
In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process.
Explanation:
What process in prophase 1 causes DNA to switch
places on separate chromosomes?
Explanation:
Recombination Occurs During the Prolonged Prophase of Meiosis I. Prophase I is the longest and arguably most important segment of meiosis, because recombination occurs during this interval. For many years, cytologists have divided prophase I into multiple segments, based upon the appearance of the meiotic chromosomes.

1. how many chambers does the human heart have?
2. what close the valves in the heart and why should they do this?
3. what do we call a pulse?
4. describe blood capillaries
Your heart has four separate chambers that pump blood, two on the right side and two on the left.
2. When the ventricle relaxes, the aortic valve closes to prevent blood from flowing back into the ventricle. When the aortic valve is not working properly, it can interfere with blood flow and cause the heart to strain to send blood to the rest of the body.
3. In medicine, a person's pulse is a pressure wave caused by the expansion of the arteries as a result of the circulation of blood pumped by the heart.
4. Capillaries are tiny vessels that branch out from arterioles to form networks around body cells.
Capillaries are very tiny blood vessels — so small that a single red blood cell can barely fit through them.

A glacier advanced 12 feet during a 16-day period in January. The same glacier advanced 18 feet during a 24-day period in February.
Are the ratios of feet to days proportional for these two periods of time?
Drag and drop to correctly complete the statement.
Answer:
3 feet : 4 days
Explanation:
Ratio of feet to days in January: Ratio of feet to days in February:
12 feet to 16 days 18 feet to 24 days
Now let us reduce both to the lowest terms and compare;
Divide by 4 Divide by 6
3 feet : 4 days 3 feet : 4 days
For both time periods, the ratio of feet to days are the same.
Answer:
proportional

3. What temperature and density changes occur in a fluid or gas material that cause convection to occur?
Answer:
There is an increase in density and a corresponding increase in the temperature of the fluid
Explanation:
The temperature and density changes occur in a fluid or gas material that cause convection to occur include increase in density and a corresponding increase in the temperature of the fluid.
This is because convection involves the movement of fluids from a hotter area to a colder area and hot fluids usually have a lower density.

Scientists count the number of organisms in the tallgrass prairie. Which trophic level would you
expect to contain the smallest number of organisms?
A. Producers
B. Primary consumers
C. Secondary consumers
D. Tertiary consumers
Scientists count the number of organisms in the tallgrass prairie. The trophic level would you expect to contain the smallest number of organisms is Tertiary consumers. Thus, option D is correct.
Who are known as producers?The organisms that are capable of making their food like plants are called producers. The organisms that feed on the producers are known as primary consumers. The primary consumers include all kinds of insects, caterpillars, termites, etc.
Tussock larvae would be a primary consumer. The organisms that feed on the primary consumers are termed as Secondary consumers. In this example, the birds are eating the primary consumer i.e tussock larvae, hence birds would be the secondary consumers.
Therefore, Scientists count the number of organisms in the tallgrass prairie. The trophic level would you expect to contain the smallest number of organisms is Tertiary consumers. Thus, option D is correct.

Plants vs animal Behavior Examples
Answer:
Behavior is the way that all organisms or living things respond to stimuli in their environment. Stimuli include chemicals, heat, light, touch, and gravity. For example, plants respond with growth behavior when light strikes their leaves.
Examples of this kind include the nest-building behavior of birds and the dam-building behavior of beavers. Imprinting. An example of animal behavior that combines instinct and learning is imprinting, often seen in birds such as geese and ducks.
