When pre-existing rocks are altered by heat, pressure, or reactive fluids like hot, mineral-rich water, the resulting rocks are known as metamorphic rocks. Thus, option A,B is correct.
What are the characteristics of metamorphic rocks?Metamorphic rocks are produced when rocks are subjected to conditions such as high pressures, high temperatures, hot fluids rich in minerals, or, more usually, some combination of these.
The most prevalent elements in the Earth's crust, silicon and oxygen, are found in the majority of the minerals that make up rocks. One of the most common sedimentary rocks is limestone.
Therefore, extreme heat and pressure and existing rocks are the characteristics of metamorphic rocks.

6. What is a homogeneous solution? What is another name for this? What is the other type of solution? Find and example of both
Answer:
A homogenous solution is uniform throughout. Meaning that it has the same composition/looks the same through out the solution. It can be called a homogenous solution or mixture. The other type of solution is a heterogenous solution. This solution is is visibly different looking, so it does not look the exact same throughout.
eg:
Milk is an example of a homogenous solution. It looks the same all throughout but when you look at it under a microscope you can then see it is actually consisted of different things.
Sand in a cup of water is a heterogenous solution. You are able to visibly see the different compounds that make up the solution.

Which two body systems maintain the level of glucose in the blood?
Answer:
The endocrine functions of the pancreas and liver coordinate efforts to maintain normal blood glucose levels.
The pancreas and liver regulate the level of glucose in the blood.
What is diabetes?Maintaining blood glucose is important for the body. The body needs glucose for the production of energy. The inability of the body to regulate blood glucose results is a result of diabetes. The blood glucose in our body is maintained by two hormones.
Insulin reduces the amount of glucose in the blood and glucagon increases the amount of glucose in the blood. Insulin and glucagon work together, in people without diabetes to maintain the blood glucose level of the body.
But in people affected by diabetes, insulin has either stopped working or insulin production by the body is inadequate compared to the body's requirements.
In type 2 diabetes, insulin production is low and in type 1 diabetes, there is resistance to insulin.
Insulin and glucagon are produced by the islets of Langerhans cells of the pancreas. In excess of insulin, the liver stores glucose from the blood, and in excess of glucagon, glucose is released by the liver into the blood.
Therefore, the pancreas and liver regulate the level of glucose in the blood.

The image shows a spruce tree, which is a gymnosperm.
Which characteristic can be used to classify the tree as a gymnosperm rather than "any other type of seed" plant?
naked seeds
green leaves
thick bark
tall height
Answer: Naked Seeds
Explanation:
Gymnosperm means 'naked seed' and these were the earliest trees to evolve. They do not produce flowers and have seeds which are directly exposed to the air for wind pollination. Pine cones are one example. For ease you might think of the gymnosperms as conifers, such as yew and Scots pine.
The exposed seeds characteristic can be used to classify the tree as a gymnosperm rather than "any other type of seed" plant.
What is gymnosperm?Gymnosperms are a small category of plants that don't blossom and produce "exposed seeds."
Unlike angiosperms, or flowering plants, whose seeds are enclosed by fully developed ovaries, or fruits, gymnosperms, or any vascular plant, reproduce by the use of an exposed seed, or ovule.
Many gymnosperms bear their seeds in cones, which are known as "exposed seeds" because they are not visible until they are fully developed.
This means that unlike in a fruit, where the seeds are formed inside the reproductive structure, they are produced on the surface of the reproductive structure.
Therefore, option A is correct.
