b. They burst as one to move from outside to inside the cells as a result of osmosis
c. No change occurs as water freely diffuses back-and-forth across the cells membrane
d. DeSales expand energy pumping water out in response to the great external salt concentration
Answer:
The correct answer would be a. They shrink as water moves from inside to outside the cells as a result of osmosis.
Osmosis refers to the movement of water from the region of high solvent or water concentration to the region of low solvent or water concentration.
In this condition, the concentration of water in a concentrated salt (hypertonic) solution would be less as compared to that of a red blood cell.
Thus, the water from inside the cell will move outside the cell. Consequently, the cell would shrink in size.
If we place human red blood cells in a concentrated salt solution, then they shrink as water moves from inside to outside the cells as a result of osmosis.
Further Explanation:
Osmosis refers to the spontaneous movement of the solvent particles via a semi-permeable membrane from a lower to the higher region of concentration, in the direction which tends to maintain equilibrium onto both sides.
For a cell to survive, the ion concentrations outside and inside the cell should be the same. Also, the water concentration is limited because a higher concentration of water can burst and swell the cell. Osmosis is crucial in the biological systems as the membranes are semi-permeable. Also, focus on maintaining the equilibrium on both sides and prevent the bursting of the cell. If a blood cell is placed in a beaker that is filled with the concentrated salt solution then the solvent present in the cell moves outside to the cell to maintain the homeostasis of the cell this phenomenon is mainly known as exo-osmosis.

b. A monarch's power comes from God.
c. God ensures that bad things don't happen to good people.
d. God created an ordered universe but does not intervene in people’s affairs.
Correct answer: D. God created an ordered universe but does not intervene in people's affairs.
Further detail:
Deism and rational religion were popular approaches to religion by philosophical thinkers during the Enlightenment. John Locke was one of the early proponents of this sort of approach to thinking about God. Deists (or we could say "God-ists") believed in God, but as a rather remote Being who had created the universe by his power and embedded in it natural laws that allowed it to run on its own from there. Some have compared it to viewing God as the "great watchmaker" who designed the universe as a perpetual watch or clock that could run on from there without needing his personal intervention in daily affairs of earthly life.
Answer: "The synovial fluid in my joint capsule acts as a lubricant and helps the movement of the joint's articulating surfaces."
Explanation:
Synovial fluid is also called Synovia. It is produced by the synovial membrane. It is a thick liquid found in the cavities of synovial joints. It's function is to reduce friction by acting as a natural lubricant between the articular cartilage of synovial joints and allows ease of movement, they act as shock absorber and nourishment in the joints. Each of the joints contain synovial fluid.
B) it gets more direct sunlight.
C) the Earth is closer to the Sun.
D) it is tilted away from the Sun.
Answer:
Option (B)
Explanation:
When the tilt of the earth is towards the sun, then it is called summer in the northern hemisphere. In this position, the sunlight is directly over the earth, as a result of which it absorbs more amount of heat. Spring is the season that starts from about 21st March to 21st of June or it can be considered as the season that exists between the summer and winter. Here, a high amount of sunlight is absorbed due to which the temperature eventually rises.
This is the reason why the northern hemisphere is relatively warmer during the spring season than in winter.
Hence, the correct answer is option (B).
The completed question is,
Identify the biotic factor of an ecosystem from the following:
a. soil composition
b. trees
c. temperature
d. sunlight
Option b. trees are the biotic factor of an ecosystem.
An ecosystem includes all the organisms and the physical environment with which they interact. These biotic and abiotic components exist linked together through nutrient cycles and energy flows. The energy penetrates the system through photosynthesis and exists incorporated into plant tissue.
The primary types of ecosystems are forests, grasslands, deserts, tundra, freshwater, and marine. The word “biome” may even be used to represent terrestrial ecosystems that extend across a large geographic area, such as the tundra.
With the provided choices. it exists trees that are categorized as biotic factors of an ecosystem. Biotic factor guides living things found in the ecosystem. Trees exist as living things that furnish oxygen for humans and animals to live.
Hence, Option b. trees are the biotic factor of an ecosystem.
