2. What does letter B represent on the Earthquake model?
A:Epicenter
B:Focus
C:P wave
D:O S wave
Answer:
A.
Explanation:
The letter B represents the Epicenter of the earthquake.
The focus would be the letter A and C would be called the fault.
The epicenter is the point closest to the point where the earthquake originated but on the surface and not underground. The hypocenter is the point within the earth where an earthquake rupture starts.

How do greenhouse gases affect Earth?
A. They cause wind currents to increase.
B. They decrease ocean currents, cooling the planets.
C. They stop heat from escaping the atmosphere.
D. They reflect sunlight away from Earth.
Answer:
the answer is c
Explanation:
Greenhouse gases affect Earth because They stop heat from escaping the atmosphere.
Thus, A greenhouse is a glass-enclosed building that can be used to cultivate plants. The greenhouse's air and plants are warmed by the sun's rays.
The heat that is trapped inside is unable to escape, warming the greenhouse, which is necessary for the plants' growth. The atmosphere of the earth is the same.
The atmosphere of the planet warms during the day due to the sun. The heat is radiated back into the atmosphere at night when the earth cools. The greenhouse gases in the earth's atmosphere absorb the heat throughout this process.
Thus, Greenhouse gases affect Earth because They stop heat from escaping the atmosphere.

Answer:
Field study
Explanation:
I took the quiz and got it right. Hope this helps :)
The type of research method that would best answer the given question is field study. The correct option is C.
What is field study?Field studies are research activities that take place outside of your office or lab, in the context of the user.
There are numerous field-study methods and activities to choose from. Field studies also differ significantly in terms of how the researcher interacts (or does not interact) with participants.
Field research is a qualitative research method that involves observing and interacting with people in their natural settings in order to understand and interpret the social interactions of groups of people, communities, and society.
Field studies provide students with first-hand experiences that promote critical thinking, long-term retention, transferability, positive attitudes toward science, appreciation for nature, and increased scientific curiosity.

What does a cell have to do to move a substance from an area of low concentration to an area with high concentration
Answer:
The cell has to undergo a process called Osmosis
Cell performs diffusion and osmosis to move substances from an area of low concentration to an area with high concentration through the semi-permeable membrane.
What is Cell transport?
Cellular transport is the mechanism through which substances move from a region of low concentration to a region of high concentration. Cellular transport takes place through osmosis and diffusion.
In osmosis and diffusion, the particles such as water and ions move due to concentration gradient from a region of high concentration to the region of low concentration of particles through the cell membrane. The membrane allows the movement of non-polar substances through membrane however some particles are unable to cross the membrane and thus requires transport proteins which facilitates their movement.

What part(s) of photosynthesis would the plant not be able to perform if there were no rain?
Answer:
When plants are not watered properly they wilt. ... When a plant is properly hydrated, there is enough water pressure to make the leaves strong and sturdy; when a plant doesn't get enough water, the pressure inside the stems and leaves drops and they wilt. Plants also need water for photosynthesis.
Plants wilt when they are not adequately watered. When a plant receives enough water, the water pressure inside the stems and leaves rises and causes the plant to flourish.
What is photosynthesis?The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.
When a plant does not receive enough water, the water pressure inside the stems and leaves decreases and the plant wilts. Water is also required by plants for photosynthesis.
Photosynthesis is essential to most life on Earth. Plants, algae, and some types of bacteria carry out the process by capturing solar energy to create oxygen (O2) and chemical energy stored in glucose (a sugar).
Therefore, Plants wilt when they are not adequately watered. When a plant receives enough water, the water pressure inside the stems and leaves rises and causes the plant to flourish.

Compare the three types of RNA. Note significant similarities and differences. Use the table below to record your observations. basically just finish this table lol...
Answer: (Structure) mRNA: always single stranded, rRNA: single stranded, twisted upon itself in some regions, tRNA: cloverleaf-like structure
(Function) mRNA: carries the information in the DNA to the ribosomes where it is translated into amino acids of proteins, rRNA: helps assemble tRNA, mRNA, and amino acids to form the polypeptide chain during protein synthesis, tRNA: acts as an adaptor molecule, which identifies correct amino acids corresponding to the anticodon present on it
Explanation: Plato, you're welcome
(Structure) mRNA: always single stranded, rRNA: single stranded, twisted upon itself in some regions, tRNA: cloverleaf-like structure.
(Function) mRNA: carries the information in the DNA to the ribosomes, rRNA: helps assemble tRNA, mRNA, and amino acids to form the polypeptide chain, tRNA: acts as an adaptor molecule.
What is mRNA, rRNA and tRNA?mRNA carries instructions from the DNA to the ribosome work site. rRNA forms part of the structure of the ribosome and helps to connect pieces together. tRNA brings in the amino acids, which are the pieces that get strung together to make the final protein.
Moreover, the three major types of RNA are: mRNA (messenger RNA) : it provides the template for protein synthesis during translation, tRNA (transfer RNA) : it brings amino acids and reads the genetic code during translation, rRNA (ribosomal RNA) : it plays a structural and catalytic role during translation.
Therefore, the main difference between mRNA and tRNA is that mRNA serves as the messenger between genes and proteins whereas tRNA carries the specified amino acid into the ribosome in order to process the protein synthesis.

b) it will become the plant's seed leaves
c) it protects the plant embryo
d) it provides nourishment for the growing plant
Answer:
It's D
Explanation:

Endosperm regulates seed development and facilitates the transmission of maternal nutrients to the embryo. Therefore, option (D) is correct.
What is endosperm?The endosperm is a type of tissue that develops during fertilization and is found inside the seeds of most angiosperm plants. It gives the embryo the nutrients it needs to grow.
Endosperm is produced when the two sperm nuclei that are contained within a pollen grain make their way into the interior of a female gametophyte.
The endosperm contains carbs, protein, and minor amounts of B vitamins and minerals. These components affect our bodies differently: Bran and fiber inhibit starch digestion, preventing blood sugar increases.

PS: Love you babe ill see you when you get home.
A dry soil sample has a volume of 500 mL. After 400 mL of water are added to the soil, the soil becomes saturated with 150 mL of surface water left on top. The porosity of the soil is 50%. Thus, option C is correct.
What is Forest soil?Forest soil has more moisture than sandy soil therefore the types of plants that are grown in soil of forests are more qualitative and more superior than the sandy plants which are facing certain limitations and facing certain situations.
Forest soil supports plant life, but sandy soil does not support any plants. Forest soil produces more superior life and the plants life are found in the forest area and the sandy plants are lesser found in the sandy areas.
The reason for vegetation in forests is because of the supportive factors that are involved in the good plants life. The soil type that is the richest in organic material would be a dark-colored soil. Decaying matter turns brownish-black which makes this type of soil having a dark color even almost black.
Therefore, A dry soil sample has a volume of 500 mL. After 400 mL of water are added to the soil, the soil becomes saturated with 150 mL of surface water left on top. The porosity of the soil is 50%. Thus, option C is correct.
