Seed Germination Investigation
The students are to investigate the process of seed germination during their summer
vacation.
They will select different types of seeds, such as beans, peas, or sunflower seeds.
Encourage students to set up a germination experiment by placing the seeds in
different conditions, such as light vs. dark, or wet vs. dry. Moreover, they need to
pot the same seed in more than one pots.
They should observe and document the changes that occur over time, including the
emergence of roots and shoots.
Answer:
Okay...In this case I suggest you use corn seed or beans seed
Explanation:
It should take about 6 weeks to see the Germination, until then continue watering it and giving it sunlight

create a new species.
Answer:
b) cause a mutation
Explanation:
here's my thinking- since the DNA looks as if it's going through a change, i know that another word for change is mutation and also by g00gle definition-
transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). the newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation.
good luck :)

What best describes ribosomes?
Ribosomes are cellular structures that synthesize proteins from amino acids. They are composed of ribosomal RNA and proteins and are found in both prokaryotic and eukaryotic cells.
Ribosomes are essential for gene expression and cell growth. They can be free in the cytoplasm or bound to the endoplasmic reticulum or the nuclear envelope.
An example of a ribosome function is the translation of a messenger RNA (mRNA) sequence into a polypeptide chain. The ribosome reads the mRNA codons and matchesthem with the corresponding transfer RNA (tRNA) anticodons that carry the amino acids. The ribosome then forms a peptide bond between the amino acids and releases the tRNA. This process continues until the ribosome reaches a stop codon on the mRNA and terminates the protein synthesis.
Answer:
A ribosome is a intercellular structure made of RNA and protein

why are all solar eclipses visible from a much smaller part of Earth than lunar eclipses?
The ocean is one of Earth’s biomes. A biome is an area that is characterized by the plants and animals that live there. There are five major oceans—the Atlantic, Pacific, Indian, Arctic, and Southern—that are all connected in what is known as the World Ocean. The ocean, sometimes called the marine biome, is huge, covering 70% of the Earth’s surface. However, humans have only explored about 5% of it. Scientists know less about the ocean than they do about the dark side of the moon. In this way, the ocean is considered the Earth’s final frontier.
Which of the following is true?
A
The Atlantic, Pacific, Indian, Arctic, and Southern Oceans are completely separate from each other.
B
The ocean covers about half of the Earth’s surface.
C
Scientists have studied most of the ocean, but a tiny bit remains unexplored.
D
Scientists know more about the moon than they do the ocean.
The statement that scientists know more about the moon than they do about the ocean is true. Therefore, the correct option is D.
While the ocean covers a significant portion of the Earth's surface, human exploration and understanding of its depths are still limited. Only about 5% of the ocean has been explored and studied, leaving a vast majority uncharted.
In contrast, scientific missions, including manned and unmanned missions, have provided substantial information about the moon's geology, surface composition, and other characteristics.
This knowledge is largely due to the numerous space exploration missions that have been conducted over the years, allowing scientists to gather data and insights about the moon's features and history.

C. Regions near the equator are highest in elevation.
D. Regions near the equator receive fewer hours of direct solar energy.
Answer: Hi! The correct answer for Question 1 is C, and for 2 is A. Brainliest?
Explanation:
Question 1: The correct answer is C. The Gulf Stream current brings warm water to the western coast of Europe, which helps to moderate the climate and keep temperatures warmer than other areas at the same latitude.
Question 2: The correct answer is A. Regions near the equator receive solar energy at a more direct angle, which results in more intense heating of the surface and warmer temperatures. This is why areas near the equator are generally hotter than areas at higher latitudes.
Answer:
Question 1: C.
Question 2: A.
Explanation:
Question 1:
Warm water is brought in by the Gulf Stream to western Europe, making the air and the climate warmer as well.
Question 2:
At the equator, the Earth is closer to the Sun, and so the energy released from the Sun is focused more on the equator than it is on other parts of the Earth.
List 3 negative impacts does plastic pollution have on the ocean?
Answer:
Negative physical impact on marine life, chemical impact on the water, and transport of native species.
Explanation:
Negative physical impact on marine life:
Plastic can be dangerous to creatures living in the ocean. Marine animals can fatally swallow plastic, become entangled in it, and even become physically impaired for the rest of their life.
Chemical impact on the water:
Plastics carry chemicals such as PCBs and DDT that can invade the water and cause harm to marine ecosystems.
Transport of native species:
Plastic can carry organisms from one part of the ocean to a relatively remote area. By introducing new organisms to an ecosystem, the flow can be disrupted and result in major consequences.

what is the geocentric model (please give simple answer and this is for my notes so there is no choices to pick from)
The geocentric model is a cosmological model that places the Earth at the center of the universe. This model was the prevailing view of the cosmos for centuries, and it was supported by the apparent daily movement of the Sun, Moon, and stars across the sky.
However, the geocentric model was eventually disproven by the heliocentric model, which places the Sun at the center of the universe.
The geocentric model was first proposed by the ancient Greek philosopher Ptolemy in the 2nd century AD. Ptolemy's model was based on the observation that the Sun, Moon, and stars all appear to move across the sky in a regular and predictable way.
He also observed that the planets appear to move in a looping pattern, which he explained by proposing that they orbit the Earth in a series of nested spheres.
Ptolemy's model was very successful in explaining the apparent motions of the Sun, Moon, and stars. However, it was not without its flaws.
For example, the model required the introduction of a number of epicycles, which were small circles that were attached to the larger circles that the planets orbited. These epicycles were necessary to explain the looping motion of the planets.
The geocentric model was eventually disproven by the heliocentric model, which was proposed by the Polish astronomer Nicolaus Copernicus in the 16th century.
Copernicus's model was based on the observation that the planets all orbit the Sun in the same direction, and that they all have nearly circular orbits. He also observed that the Earth rotates on its axis once every day and that it orbits the Sun once every year.

Describe how heat moves in a convection current. How is this process responsible for moving earth’s tectonic plates?
Explanation:
Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat. ... Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.
Existing rocks are buried and forced toward the mantle, increasing heat and pressure. This is the first step in the formation of metamorphic rocks.
(PLEASE HELPPPP 90 POINTS!!)
Which best describes the next step in the formation of metamorphic rocks?
Buried rocks melt deep within the mantle.
Lava melts underlying rocks, which crystallize into new minerals.
Rocks that were buried are exposed at Earth’s surface, where they are weathered and eroded.
Magma pockets rise, which increases heat, and minerals change due to temperature and pressure.
