Next Sandra tests the hardness of each mineral by scratching it with different materials as shown in the chart. The values in the chart are based on the Mohs Scale of hardness, which ranks the hardness of minerals on a scale of 1 to 10. The harder the mineral is, the higher its rating will be. If the material is harder than the mineral, it will scratch the mineral. For example, according to this scale, if a mineral is unable to be scratched by a steel nail, then the mineral has a hardness greater than 6.5.

Which of the following structures would normally be found in a plant cell but not in an animal cell? A. cell wall B. cell membrane C. nucleus D. vacuoles
Answer: A) Cell wall
Explanation:
Please note that because it says normally not in an animal cell, the answer may be vacuole, which are rarely in animal cells. However, because cell walls are never found in animal cells, I went with that.
Hope it helps <3
Answer:
Cell Wall
Explanation:
Animals have only cell membrane due to which they move but Plants have cell wall due to which they don't move
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.

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.
why food chains cannot have a large number of trophic levels
Answer:
the energy is only taken at a fraction from the previous level because of the actual predation taking lots of energy. this keeps going until the top trophic level gets less energy that in needs to survive
Explanation:
Answer:
Because of the high rate of energy loss in food chains, there are usually only 4 or 5 trophic levels in the food chain or energy pyramid. There just is not enough energy to support any additional trophic levels.

Internal and External Structures
You are now going to construct an argument that plants have internal and external structures that support growth and reproduction.
Choose the internal and external structures you want to gather evidence and create a statement about.
subject: sciences
Explanation:
Some structures are internal, like the lungs, brain, or heart. Other structures are external, like skin, eyes, and claws. Some structures are unique, like the long neck of a giraffe. Other structures are more common, like a heartStructure and Function: Plants and animals have both internal and external structures that serve various functions in growth, survival, behavior, and reproduction.
A student is studying a gray pine (conifer/gymnosperms), an apple tree and an avocado tree. After conducting research about them she discovers some similarities and differences between them. What are some of the differences and similarities she probably discovered? (Hints: think about how they reproduce)
In terms of reproduction, what is an example of a dependent relationship between a plant species and an animal species? What do you think would happen if the population of one of the species decreased?
A dependent relationship between a plant species and an animal species is when the population of one of the species decreases. This can happen by disease, or by loss of habitat. The result of this decrease is that the population of the other species will increase.
For example, if a plant species is plentiful and an animal species is more scarce, then it will be less likely for an individual animal to find food. This could cause an increase in death rates among animals who are unable to find enough food or food sources that are not well-suited for their diet. In turn, this loss in population would lead to fewer births as well as lower survival rates.
If the population of one of the species decreased, it would mean that there would be less plants or animals to feed off of. This could lead to a decrease in food supply for either plant or animal species. It is possible that this could cause a decrease in population as well.

Explanation:
Label the Big Dipper, Little Dipper, and indicate the Polaris.
The Polaris lies in a direct line with the Earth's rotational axis, which is "above" the North Pole (north celestial pole). Its stands almost motionless in the sky, and all the stars of the northern sky appear to rotate around it. The attached image is a clear indication.
How can we describe the Polaris location in the sky?The Polaris appears to remain stationary in the sky while all other stars appear to rotate around it. To locate Polaris in the sky, one must first find the Big Dipper, which is a well-known group of seven stars that resemble a ladle or dipper. If one follows the two stars at the end of the bowl of the Big Dipper, they will point directly to Polaris.
Once located, Polaris can be used as a guide to determine one's direction when navigating at night. Because it is very close to the celestial north pole, its position in the sky is directly above the Earth's geographic North Pole. This makes it a reliable reference point for navigation in the Northern Hemisphere.

There is more than one way to produce the amino acids that build a protein. What does this mean?
The statement that there is more than one way to produce the amino acids that build a protein means that there are multiple ways that the body can obtain the necessary amino acids from the nutrients.
What is protein?There are two main ways that the body can obtain these amino acids: through dietary intake and through the breakdown of existing proteins in the body. The human body cannot produce all the amino acids it needs on its own, so it must obtain the remaining amino acids through the diet. These are known as essential amino acids, and they include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Hence, there is more than one way to produce the amino acids that build a protein, meaning that there are multiple ways that the body can obtain the necessary amino acids from the nutrients.
