Explanation:
A) The mud in Amal's beaker will settle down at the bottom of the muddy water if left overnight with clear water occupying the surface. This is because the particles of mud are insoluble in water and will settle down at the bottom of the muddy water if left undisturbed for a while.
B) The process is called sedimentation. The settled mud particles are referred to as the sediments and the clear water at the top can be decanted off to separate the sediment from the water.

A food chain consists of several organisms. Suppose one of the organisms in the chain disappears. What effect can this have on the other organisms in the food chain?
Answer:
All organisms in that food chain would starve until they die unless they could possibly move to a different habitat.
Explanation:
And because of all those organisms not being able to properly feed due to an organism missing in the food chain of that habitat, the population of those animals would decrease as well.

Organic compounds contain carbon atoms bonded to other atoms. The correct option is A.
What are organic compounds?Any of a wide area of chemical compounds in which one or many carbon atoms are covalently connected to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.
Carbides, carbonates, and cyanides are among the few carbon-containing compounds that are not classified as organic.
The main distinction between organic and inorganic compounds is that organic compounds always contain carbon, whereas most inorganic compounds do not.
Furthermore, almost all organic compounds contain carbon-hydrogen or C-H bonds.
Organic foods are grown without the use of synthetic pesticides, fertilizers, or herbicides.
Organic meat, eggs, and dairy products are derived from animals that have been fed natural feed and have not been given hormones or antibiotics.
Thus, the correct option is A.

A) Absorbs nutrients
B) Absorbs vitamin/s minerals
C) Absorbs foods/glucose
D) Increases surface area for absorption
E) All of the above
Answer:
D) Increases surface area for absorption
Explanation:
Microvilli are microscopic structures found mostly attached to the epithelial cells of certain organs. Microvilli helps the organs their found to increase the surface area for the diffusion of substances.
For example, microvilli in the epithelial cells of the small intestine helps to increase the surface area for the absorption of nutrients in the blood.
Empty stomachs contract, causing both hunger pangs and the secretion of chemical messages that travel to the brain to serve as a signal to initiate feeding behavior. This is an example of ________. Group of answer choices
Answer:
How physiological mechanisms serve as the basis for hunger
Explanation:
Physiological mechanisms are able to provide explanations to body functions, events and outcomes. Such mechanisms could be altered voluntarily when there's the need to. Hunger is on example of such. When a person is hungry the muscles of the stomach contracts and messages are sent to the brain. This process is what tells the person thaat he needs to feed.

Why does the thermosphere increase in temperature as altitude increases?
Answer:
The thermosphere is the outer layer of the Earth's atmosphere, extending from about 53 miles to more than 370 miles above the surface. The temperature increases rapidly in this layer due to the absorption of huge amounts of incoming high energy solar radiation by atoms of nitrogen and oxygen.

Explanation:
help me ..it's a MCQ
Explanation:
I think your answer is D, and let me explain why.
Heat can denature proteins quickly because proteins have very specific temperatures at which they act best. If the temperature rises too high/falls too low with respect to that threshold, then that will cause the proteins to stop working properly and eventually die.
pH is also very important with how proteins work, and it's the same reason as heat. Proteins have a certain range of pH's that keep them healthy and working, but as soon as the pH changes dramatically outside of that range, the proteins will be quickly denatured.
And lastly, organic solvents can denature proteins as well (e.g. alcohol), which makes sense because they are solvents (a solvent is something that dissolves other substances). I'm not sure about the exact chemistry / biological responses behind it, but it's what would be expected of a solvent.
With all of this in mind, I think your answer should be D!
The continental crust covers ____ of the earth's surface a. 40% b. 50% C. 60% d. 70%
Answer:
a. 40 percent
Explanation:
Answer:
a. 40%
Explanation:
The continental crust covers 40% of the Earth's surface.
At 25 to 70 km, continental crust is considerably thicker than oceanic crust, which has an average thickness of around 7–10 km. About 40% of Earth's surface area and about 70% of the volume of the Earth's crust is the continental crust. Most continental crust is dry land above sea level.

Which of the following adaptations enables deciduous trees to produce more food?
a.
broad leaves
b.
thick bark
c.
leaf loss
d.
color change
The presence of broad leaves, which is present in Option A, enables deciduous trees to produce more food. Broad leaves have the benefit of increasing the photosynthetic rate, resulting in more food production.
What is the role of the leaves?Leaves are of many types, such as the neddle-shaped leaf and flat leaves, and all these leaves are adapted to different climatic conditions. The plants that are present in the tropical area have comparatively flat leaves compared to those that are present in the cold areas in order to control transpiration and heat.
Leafy plants that are green in color have chloroplasts and chlorophyll pigments that help in the photosynthesis process. Because the photosynthesis process produces food, if the leaf is green, it has more chloroplasts and thus produces more food.
Hence, The presence of broad leaves, which is present in Option A, enables deciduous trees to produce more food.

Recently discovered genetic evidence shows that multicellular land plants such as corn and wheat, are all of one lineage – they all arose from a single type of algae. Fossil evidence suggests that other types of algae did not have the needed complexity to move into terrestrial ecosystems. Explain at least 3 adaptations that algae would need to be able to survive on land.
Answer:
1) they would need a host or vessel to stay on and feed of of their body
2) they would need some for of reproduction in the host ( mitosis whatever the algae my use )
3) they would need to wisely choose there hosts and of what they feed on so there host doesn’t die quickly
I don’t know if this is what your looking for but these are 3 things that algae would need to live
