Answer:
D, or hornfels.
Explanation:
Hornfels is a metamorphic rock formed by the contact between mudstone / shale, or other clay-rich rock, and a hot igneous body, and represents a heat-altered equivalent of the original rock. This process is termed contact metamorphism. It's not like animal metamorphism.

4. How would having a high blood viscosity affect your ability to climb stairs? Explain your answer interms of homeostasis of oxygen/carbon dioxide levels
Having a high blood viscosity will slow down ability to climb stairs. This is
because high blood viscosity is associated with high blood pressure.
The binding of oxygen to the blood is reduced in a blood with high viscosity
as there is difficulty in the transport of blood for oxygenation due to its
higher density. This allows fro accumulation of carbon dioxide in the blood
which is harmful to body cells.
High blood viscosity will therefore reduce one's ability to climb stairs and
perform other activities.

explain how redox reactions are involved in energy exchanges
Answer:
In redox reactions, energy is released when an electron loses potential energy as a result of the transfer. Electrons have more potential energy when they are associated with less electronegative atoms (such as C or H), and less potential energy when they are associated with a more electronegative atom (such as O).

what is the specific function of the structure labeled f?
Answer:
The muscle spindle indicated by F functions as a proprioceptor that is responsive to changes in the length of the surrounding muscle.
Explanation:
The specific function of the structure labeled f is proprioceptor that is responsive to changes in the length of the surrounding muscle.
What is the function of the muscle spindle?The muscle spindle is activated whenever the weight of the body, tending to bend the knees, stretches the muscles. Stimuli are sent to the spinal cord and through the motor nerve and the muscles contract to counteract the action of gravity.
The Muscle spindle is a proprioceptive sensory receptor spindle composed of muscle bundle fibers. Its main function is to signal changes in the length of the muscle on which it is located. Muscle Spindles are structures responsible for mechanical myo-integrity and regulation of muscle contraction/distension.

1. Why does the angle of the sun at noon seem to change at different months throughout the year?
2. How does this create seasons?
Answer:
1. The earth orbit is slightly elliptical, and the earth axis is tilted by roughly 23.5° to the orbit. These to factors combine to make the an analemma. But in the winter, When the Earth is on the other side of orbit, the Earth's north pole is tipped away from the Sun, so at noon the sun doesn't get as high.
2. The earth's spin axis is tilted with respect to it's orbital planet. This is what causes the season. When the earth's axis points towards the sun. it is summer for that hemispheres. Midway between these two times in spring and autumn, the spin axis of earth points 90 degrees away from the Sun.
Which mechanism allows lipid-soluble substances to move through the membranes of endothelial cells of capillaries
Answer:
Diffusion.
Explanation:
The mechanism that allows lipid-soluble substances to move through the membranes of endothelial cells of capillaries is simple diffusion.
Simple diffusion is a passive transport mechanism that allows lipid-soluble substances to move across the membranes of endothelial cells in capillaries. This process occurs down a concentration gradient, from an area of higher concentration to an area of lower concentration, without the need for energy expenditure.
The membranes of endothelial cells, which make up the walls of capillaries, are composed of a lipid bilayer. Lipid-soluble substances, such as oxygen, carbon dioxide, steroid hormones, and certain lipid-soluble drugs, can readily diffuse through this lipid bilayer due to their ability to dissolve in and pass through the hydrophobic interior of the membrane.
Unlike lipid-soluble substances, water-soluble substances, such as ions and polar molecules, are unable to passively diffuse through the lipid bilayer. Instead, they rely on specific transport mechanisms such as facilitated diffusion or active transport to cross the endothelial cell membrane.
In the context of capillaries, simple diffusion allows lipid-soluble substances to move from the bloodstream through the endothelial cell membranes and into surrounding tissues or vice versa. This process plays a crucial role in the exchange of gases, nutrients, and waste products between the bloodstream and the tissues.
It is important to note that while simple diffusion allows for the passage of lipid-soluble substances, the movement of these substances can also be influenced by factors such as concentration gradients, molecular size, solubility, and the presence of transport proteins. However, the primary mechanism by which lipid-soluble substances traverse the endothelial cell membranes of capillaries is through simple diffusion.

what would happen to the carrying capacity of the ecosystem & why
Q-a volcano covers an area with 2 feet of lava
Answer:
The carrying capacity would shoot downward.
Explanation:
The area would no-longer be able to support organisms or the ground until the lava cools off. Even after then, any plants that may have been there will be gone, meaning that the ecosystem can now support less herbivores, as well as less primary producers (plants).
Less plants, means less herbivores, which means less of the animals that eat the herbivores (secondary and tertiary consumers).
