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.
Therefore, the statement is false.

Why must DNA replication have to occur before a cell can divide by mitosis?
A. to cause one of the cells produced to have double the number of chromosomes as the parent cell
B. to allow crossing over to occur in each of the cells produced
C. to maintain the same number of chromosomes in the daughter cells as in the parent cell
D. to cause all of the cells produced to have half the number of chromosomes as the parent cell
Answer:
C
Explanation:
DNA replicates because the second set of DNA will move into the new cell during telophase. double-check in your text but C is the most accurate answer given. A doesn't happen unless there's a breakdown in cell division, and D is for meiosis when a diploid cell divides into a haploid cell. B could be correct but it's not entirely accurate.
Which of the following BEST explains why Earth is tectonically active?
Answer:C Earth's solid surface layer sits on a moving, semiliquid layer.
Explanation:
Earth is highly tectonically active because the solid layer of the earth sits on a moving, semi-liquid layer.
The earth's crust is broken into slabs. Together with part of the upper mantle, they form a layer called the lithosphere. These solid lithospheric bodies are called tectonic plates.

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.
A primary reason that the kidneys have one of the highest metabolic rates of all body organs is that

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"

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.
