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
The seed germination investigation during the students' summer vacation involves selecting various seeds (e.g., beans, peas, sunflower) and setting up an experiment. They will place the seeds in different conditions, like light vs. dark or wet vs. dry, and pot the same seed in multiple pots. Throughout the investigation, the students are expected to carefully observe and document the changes that take place over time, including the growth of roots and shoots. This hands-on approach allows them to gain practical knowledge of seed germination and develop essential scientific skills in observation, data collection, and documentation.

Look at the diagram of the rock cycle below.
Which part of the cycle is missing?
A.
sedimentation
B.
melting
C.
crystallization
D.
mineral integration
From the diagram of the rock cycle the missing part is ( B ) ; Melting
Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.
Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting
Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

Explanation:
Masks: As we can tell cities that have a mask mandate have lower corona numbers
Vaccines: Vaccines give your body the antibodies that it needs to protect your body from infection without the virus. RNA vaccines are better than the normal vaccines because they are going to be produced faster than normal vaccines
Masks and Vaccines technologies that have helped combat the spread of disease in cities.
What are the benefits of vaccines?A vaccine is a biological preparation that provides active acquired immunity to a particular infectious or malignant disease. The safety and effectiveness of vaccines has been widely studied and verified.
Vaccine: A preparation that is used to stimulate the body's immune response against diseases. Vaccines are usually administered through needle injections, but some can be administered by mouth or sprayed into the nose.
Subunit, recombinant, polysaccharide, and conjugate vaccines use specific pieces of the germ—like its protein, sugar, or capsid (a casing around the germ).

1.What are things that sound waves can travel through?
2.Can light waves travel through space? Explain.
Answer:
1) A few things that sound waves can go through pushing the particles of the medium, closer together, the particles that have been upset at that point push adjoining particles, prior to bobbing once again into their unique positions. An example can be a guitar string producing sounds.
2) Light waves can travel however space through a vacuum a totally airless space.
Explanation:
Answer:
1. air, water, wood, and metal
2. Yes!
Explanation:
1. because everything you can see has particles that can vibrate but if there are no particles, nothing to bump into to create that vibrate in this case sounds can't travel.
2. light waves can travel through a vacuum does not require a medium. In empty "space," the wave does not grow smaller no matter how far it "travels" because the wave is not interacting with anything else... As a "wave travels" from a source, it spreads outward in all directions.

What type of carbon cycling occurs when stored carbon in organisms is released when they die, and when carbon from dead organisms can be released underground in the form of coal, oil, or natural gas?
long-term carbon cycling
carbon storage cycling
carbon release cycling
short-term carbon cycling
Answer:
The type of carbon cycling that occurs when stored carbon in organisms is released when they die, and when carbon from dead organisms can be released underground in the form of coal, oil, or natural gas is called the geological carbon cycle. This cycle involves the long-term storage of carbon in rocks and fossil fuels like oil, coal, and natural gas. Carbon is also released back into the atmosphere through various mechanisms such as volcanic eruptions, fires, and burning of fossil fuels.
Explanation:
The carbon cycle can be divided into two main categories: the short-term carbon cycle and the long-term carbon cycle. The short-term carbon cycle involves processes that cycle carbon through the Earth system on roughly annual/decadal timescales. This includes photosynthesis, respiration, and decomposition of organic matter. The long-term carbon cycle takes millions of years to come full circle and involves the movement of carbon between rocks, soil, ocean, and atmosphere through a series of chemical reactions and tectonic activity. Carbon is stored in rocks and fossil fuels like coal, oil, and natural gas for a long time in the geological carbon cycle. Carbon is also released back into the atmosphere through various mechanisms such as volcanic eruptions, fires, and burning of fossil fuels in both short-term and long-term cycles

How did the Industrial Revolution contribute to global climate change?
A. It led to an increased use of alternative fuels other than fossil fuels.
B. It led to an increased use of coal, oil, and other fossil fuels.
C. It led to the release of chemicals that destroyed the ozone layer.
D. It led to the development of nonrenewable sources of energy. (I think it's B. Please correct me if I'm wrong.)
Answer: You're right its b.
Explanation:
Human activity has rapidly increased the emission of greenhouse gases to the atmosphere. Since the start of the Industrial Revolution, in about 1750, human activities such as burning fossil fuels, including coal and oil, have increased greenhouse gas concentrations in our atmosphere.
The idea of GMO sounds really good. Why might someone be opposed to making healthier food that lasts longer or doesn't need pesticides?
Answer:
Explanation:
Genetically engineered foods are inherently unstable. Each genetic insertion creates the added possibility that formerly nontoxic elements in the food could become toxic.
Genetic engineering can also alter the nutritional value of food.
Another hidden risk of GE foods is that they could make disease-causing bacteria resistant to current antibiotics, resulting in a significant increase in the spread of infections and diseases in the human population.
Answer:
Many people believe that GMOs are bad for their health – even poisonous – and that they damage the environment.
Explanation:
Moreover, most GM crops are either bred to withstand chemical pesticides or developed to generate insecticides themselves. When herbicides are applied on resistant crops, the weeds acquire resistance over time, necessitating the use of even more chemicals. Crops genetically modified to generate pesticides, on the other hand, create poisons that are toxic not just to pests but also to other insects such as butterflies, moths, and insect pollinators.

Were does all the energy start from ALL the organisms
Answer:
The sun
Explanation:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.
Answer:
from sun all the energy starts from All the organisms it is the fact that scientist had proven itAnalyze the given diagram of the carbon cycle.
