Over time, most lakes grow larger due to erosion. Please select the best answer from the choices provided T F.
Erosion is the scientific and environmental condition in which the surface layer of the soil gets eroded. No, lakes do not grow larger due to erosion.
What is the effect of erosion?Erosion is the abrasion process in which the top of the surface layer of the dissolved minerals, rock and soil gets eroded by the strong force of the wind and water.
Lakes or the other water bodies do not get grows larger due to erosion but gets affected by the deposition and accumulation of the soil and other materials that got eroded from the land surfaces to the sea. It can affect aquatic life and pollute the water.

A muscle moving a load goes through two phases of contraction. Which phase occurs first, and what happens inside the muscle during this phase
The phase that occurs first when a muscle carries load is called the contraction phase.
Phases of muscle contractionWhen lifting up a load, the muscle passes through some phases of contraction such as:
contraction phase andrelaxation phaseThe series of events that occurs in the contraction phase include the following:
Depolarisation and calcium ion release.Actin and myosin cross-bridge formation.Sliding mechanism of actin and myosin filaments.Sarcomere shortening (muscle contraction)Therefore the phase that occurs first when a muscle carries load is called the contraction phase.

Quincy is conducting an experiment with limestone rock. He works with five rocks and begins by recording the mass of each rock. He treats each rock with a 7 milliliters of a different liquid. Quincy added these liquids to the limestone each day for a week. At the end of the week, he measured and recorded the mass of each rock.
Mass of Rock Before (grams) Mass of Rock After (grams)
Rock 1 (Distilled Water) 20 20
Rock 2 (3% acid) 20 18

Suppose you are a chemist lost in the desert and desperately in need of water. If you had a chemistry set available, which type of reaction could you use to make water?
A) dehydration
B) exothermic
C) hydrolysis
D) redox
Answer: Hydrolysis tell me how I'm wrong
Explanation: Hydrolysis is any chemical reaction in which a molecule of water breaks one or more chemical bonds. The term is used broadly for substitution, elimination, and solvation reactions in which water is the nucleophile
Dehydration is the absence of a sufficient amount of water in your body. The best way to beat dehydration is to drink before you get thirsty. If you're thirsty, you're already mildly dehydrated, and that can cause symptoms like headache, fatigue, dizziness, and more.
Exothermic: ----> (of a reaction or process) accompanied by the release of heat.
(of a compound) formed from its constituent elements with a net release of heat.
Redox: ---> a process in which one substance or molecule is reduced and another oxidized; oxidation and reduction are considered together as complimentary processes.
"redox reactions involve electron transfer"

HELP PLS/ A large bottle with a layer of mud on the bottom is filled with pond water. Several fish and some green plants are then added and the bottle is made airtight.
When a fish in this bottle dies, the nitrogen from its body is released through the action of ______________.
A
Producers
B
Algae
C
Decomposers
D
Virus
Answer: C: Decomposers
Explanation: The mud and pond water likely contain some sort of decomposing bacteria. These bacteria can break down the complex nitrogen compounds in the dead fish, producing simple nitrogen compounds. These simple nitrogen compounds can then be used by the plants added to the terrarium.
A is wrong because producers (such as the green plants added to the terrarium) can not break down the complex nitrogen compounds in the fish's body.
B is wrong for a similar reason. Algae are primary producers. Because of this they also lack the ability to break down the complex nitrogen compounds found in the fish's body.
D is also wrong. A virus may be able to infect the fish and cause disease, but it lacks the ability to break down the complex nitrogen compounds found in the fish's dead body.
Since A, B, and D are wrong, along with the fact that we know that decomposers can break down the complex nitrogen compounds in the dead fish, we can conclude that C is the correct answer.

Write a main idea paragraph about cells in general (5 sentences) I'll mark brainliest !
Biologists recognize five levels of cell organization. The lowest and simplest is the cellular level. Organisms here are either unicellular organisms, like protozoa, or colonial organisms. Colonial organisms are composed of single-celled individuals that stay together to sustain the life of the whole colony. Next on the scale of complexity is the level occupied by tissue. A tissue is a group of similar cells that perform a similar activity. Tissues that are organized around a common function together make up an organ, the third level of complexity. The fourth level of organization is the system, formed by a group of organs that together perform a specific bodily process. The fifth and highest level is the organism level, in which body systems work together in a structure capable of independent life.
