You get home from school and grab a bag of potato chips before settling onto the couch to binge watch your newest Netflix series. A few hours later, you notice that all of the chips are gone and you feel very thirsty. You get up to go to the bathroom before grabbing a drink and notice your urine is exceptionally dark in color. Apply what you know about osmosis to explain what has happen to the cells in your body. Include the name for the type of solution the cells were in after eating and how the cells attempted to maintain homeostasis despite these salty conditions.
Answer:
Explanation:
Osmosis is the process in which the molecules of a solvent move from a region of low concentration to a region of higher concentration through a semi-permeable barrier.
While eating the chips, the salt content from the chips makes the surrounding solution of the cells to have an increase in salt concentration causing an hypertonic solution. An hypertonic solution is a solution that has more solute (salt) than the (solute in a) cell. This increase in salt concentration around the cells causes the cells to release water to neutralize the high salt concentration in the solution around the cell (in order to maintain homeostasis) which causes dehydration in the individual and hence making the individual to be thirsty. The body attempts to maintain balance by passing this excess salt out of the body in the form of urine hence the reason for the dark colour in the urine (because if the body doesn't rid itself of the high salt concentration, the cells could shrink and die as a result).

How would pepsin activity be affected if it were put in a neutral solution?
Answer:
pepsin would either work at extremely slow pace or get denatured.
The activity of pepsin would be inhibited if put in a neutral solution.
Pepsin is one of the enzymes found in the gastric juice of the stomach. It is a protease that digests protein into polypeptides , which are intermediate products of protein digestion.
A neutral solution is a solution that contains hydrogen ions and hydroxide ions at equal concentration.
But Pepsin works best in an acidic medium which is provided by the hydrochloric acid secreted in the stomach.
Therefore when pepsin is put in a neutral solution, the activities would be inhibited.

Below are the seven properties of water that make life possible on Earth. Describe five of these properties and provide an example of each:
Hydrogen bonding, cohesion and adhesion, surface tension, heat of vaporization, specific heat, density, and universal solvent
Answer:
Water in its liquid form has a boiling point temperature close to 100°C. As a result of the network of hydrogen bonding present between water molecules, a high input of energy is required to transform one gram of liquid water into water vapor, an energy requirement called the heat of vaporization.
Cohesion is responsible for the transport of the water column in plants. Adhesion is water attracted to other material.
Water has a greater surface tension than most other liquids because hydrogen bonds among surface water molecules resist stretching or breaking the surface.
Specific Heat is the amount of heat that must be absorbed or lost for one gram of a substance to change its temperature by 1*C.
Density is when hydrogen bonds in water expand as it warms and contracts as it cools. The hydrogen bonds keeps the molecules far enough a part to make ice have fewer molecules.

certain substances are placed in the beaker in given picture if the following items are placed in a water filled beaker then state in what condition it remain 1 gravel of the sand. 2 drop of sunflower oil? pls ans
Answer:
1. gravel of the sand: a part is dissolved and the remainder is grouped at the bottom of the beaker.
2. drop of sunflower oil: It is not absorbed and heaps on the surface of the water contained in the beaker.
Explanation:
Gravel of the sand is a polar substance. This means that this substance has the ability to dissolve and mix with water in a system in which both were placed together, such as a beaker, for example. However, the beaker limits the amount of water, which limits its ability to dissolve polar substances. Therefore, depending on the quantity, the gravel of the sand, when placed in a beaker with water, will dissolve, in parts, what is not dissolved will accumulate in the bottom of the beacker, because the gravel of the sand is denser than the water.
With the drop of sunflower oil the exact opposite happens. This is because drops of oil are nonpolar substances, which means that they do not have the ability to be dissolved in water. This means that when dropped into the beaker with water, the drop of sunflower oil will not dissolve, but will pile up on the water surface, because it is less dense than water.

of a marine habitat?
A.
depth of light penetration
B.
daily fluctuations in temperature
C. size of predators
D. average annual rainfall
Answer:
depth of light penetration
Explanation:
light is important in marine habitat, the distribution of organism, density and the type of organism is determined by the depth of light, the energy and how well the light can travel because most of the organism depends on light.
Green Plants, some algae and cyanobacteria survive through the production of their own food via photosynthesis. Photosynthate produced through photosynthesis is what is transported from area of production to other plant part where it is needed.
Photosynthesis can not be achieved without light penetration because light is what supplies the energy needed for the reaction.
Marine habitat refers to the distribution of organisms, plants, and aquatic animals in the oceans, seas, lakes, and ponds.
The factors such as oxygen demand and light penetration play a crucial role in determining the type and distribution of organisms in the different regions of the habitat.
Light penetration affect the marine ecosystem as:
Plants are autotrophic organisms, as they carry out photosynthesis. They are the primary producers in the aquatic ecosystem. The plants need light to perform photosynthesis. Light is directly dependent on the distribution of food, as the predators require light to find the food or prey for their survival.
Thus, light penetration plays a crucial role in determining the variety and distribution of organisms at different depths.
The correct answer is Option A.
