Explain the effect of ingesting an extremely large amount of water at the cellular, including the role of osmosis in this process
Hi, you've asked an incomplete question. Here's the full question:
In extreme cases, it is possible to die from drinking too much water. The consumption of several liters of water in a short amount of time can lead to brain edema (swelling) and death. Explain the effect of ingesting an extremely large amount of water at the level of the brain cells, including the role of osmosis in this process.
Explanation:
Note, the term Osmosis in biology refers to the movement of solvents such as water through a semipermeable membrane to a higher solute (what is dissolved in the solvent) concentrated region.
For example, when one ingests an extremely large amount of water, the osmosis process begins as the water (which is the solvent) would travel down into the cell membrane and then into the cell (which is the semipermeable membrane in this case), because of the imbalance in the concentration the cell/water level, the cell may dysfunction possibly leading to death.
The effect of ingesting an extremely large amount of water at the cellular, including the role of osmosis in this process - It creates a hypotonic environment for your body due to osmosis.
Osmosisa process in which solvent such as water moves from its higher concentration to its lower concentrationIt must be separated by a semipermeable membrane or differentially permeable membraneit does not require any extra energy, only depends on the concentration gradient.When someone ingests an extremely large amount of water at the cellular, water will diffuse into the cell and the cell will begin to swell which is known as a hypotonic environment.Learn more:

A wave hits an object as shown.
Which kind of wave interaction is shown?
Answer:
Refraction
Explanation:
The wave interaction shown is called refraction.
Refraction occurs when a wave crosses the boundary between two mediumIn this process the ray becomes bent. The density difference between the two medium accounts for the bending of the rays. When a ray crosses the boundary from a less dense to a denser medium, it is deflected to the normal as the ray slows down.Answer:
refraction

Judy used the following soil triangle to identify a sample of soil as silty clay.
Soil texture triangle. Clay soil is approximately 45 percent or less sand, 50 percent or more clay, and 40 percent or less silt. Silty loam soil is approximately 50 percent or less sand, 30 percent or less clay, and 50 percent or more silt. Sandy clay soil is approximately 45 to 65 percent sand, 35 to 55 percent clay, and 25 percent or less silt. Sandy clay loam soil is approximately 45 to 80 percent sand, 20 to 35 percent clay, and 35 percent or less silt.
Which description of soil likely allowed Judy to make this identification? (2 points)
a
Mostly large particles, with a gritty texture, 75% clay, 15% sand, and 10% silt
b
Mostly large particles, with a sticky texture, 65% clay, 10% sand, and 25% silt
c
Mostly small particles, with a sticky texture, 50% clay and 5% sand, and 45% silt
d
Mostly small particles, with a smooth texture, 30% clay, and 25% sand, 45% silt
Answer:
its C
Explanation: I worked it our w/ the triangle and this seemed the most logical answer. plus had the same question on a test ~5min before this post so I know for sure its right.
Soil texture or Soil profiling is referred to as the proportion of primarily three different types of particles, clay, sand, and silt.
The description that is similar to Judy's soil triangle is that most small particles, with a smooth texture, are 10% sand, 50% clay, and 40% silt.
The soil profiling can be explained as:
1. Clay is one of the smoothest and fine particles of the soil. It has a diameter of fewer than 0.2 millimeters. Clay soil is 40% or more is clay, less than 40% is silt, and 45% or less is sand.
2. Sand is a coarse particle and is the largest mineral in the soil. The particle is gritty and has a diameter of 0.05 to 0.02 mm.
3. Silt is found in a high percentage of the soil and gives a smooth texture to the soil.
Thus, the correct answer is Option C.

Moose populations would decrease as the moose emigrate to safer habitats
Moose populations would increase since the moose and deer can breed creating resistant moose.
Moose populations would decrease as the worm is a biotic factor that will limit the growth of their population
Moose populations would increase as weak moose are killed allowing stronger moose to give birth or immigrate into the area.

A ball bounces on the ground. How do the ball and the ground act on each other?
Explanation:
It will continue to fall under the influence of gravitational acceleration, but now, a normal force from the ground surface, opposing the force due to gravity, will act on the ball.This all means that the ball is pushing on the ground with a force greater than its own weight, so acceleration must point upward.

An organism's DNA determines the traits it will haveWhich statement correctly explains how DNA determines the organism's traits?
Answer:
This question is incomplete as it lacks options, the options are:
1- The sugar and phosphate groups that make up the backbone are used in different sequences to encode an organism’s traits.
2- The bases A, T, C, and G are always present in equal amounts, so each organism is unique.
3- The bases A, T, C, and G in DNA are used in different sequences to encode an organism’s traits.
4- The bases A, T, C, and G are always in the same order in each organism, so each organism is unique.
The answer is 3. The bases A, T, C, and G in DNA are used in different sequences to encode an organism’s traits.
Explanation:
Deoxyribonucleic acid (DNA) is the genetic material in the cells of living organisms. It is a polymer biomolecule made up of nucleotides monomers. The DNA contains information that encodes the synthesis of useful products (proteins), which determines the traits in organisms.
A DNA molecule is made up of four nucleotide subunits viz: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). These bases, which are used in different sequences, carry the information that encodes an organism's trait.

The diagram below shows two different forces acting on a cyclist riding a bicycle the total mass of the cyclist and the bicycle is 100.0 kg based on information what is the acceleration of the cyclist?
Answer:b
Explanation:
The diagram below shows two different forces acting on a cyclist riding a bicycle is 150 N and another force acting opposite to moving cycle is 84 N the total mass of the cyclist and the bicycle is 100.0 kg based on information. Thus, option B is correct.
How net force will be calculated?
The net force acting on the bicycle is:-
F net = Total force acting on bicycle
In above question,
Given the F1 = 150 N and F2 = -84 N (Negative sign shows that force is acting opposite to the motion)
So,
Fnet = F1 + F2
Fnet = 150 N -84 N
Fnet = 66 N
Now the acceleration will be
Fnet = mass X acceleration
In above question,
Fnet = 66 N
Mass = 100 Kg
So,
Acceleration = Fnet/Mass
Acceleration = 66/100
Acceleration = 0.66 m/sec^2
Therefore, The diagram below shows two different forces acting on a cyclist riding a bicycle is 150 N and another force acting opposite to moving cycle is 84 N the total mass of the cyclist and the bicycle is 100.0 kg based on information. Thus, option B is correct.
