Answer:
As a cell grows bigger, its internal volume enlarges and the cell membrane expands. Unfortunately, the volume increases more rapidly than does the surface area, and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.
Explanation:
. Unlike animal cells, plant cells have ________________¬¬¬¬¬¬¬¬¬¬, vacuoles, and a ____________ wall.
Answer:

Organ _____
are made of multiple organs that work
together to maintain homeostasis in an organism.
Answer:
systems
Explanation: Cells are organized into tissues, and tissues form organs. Organs are organized into organ systems such as the skeletal and muscular systems. All of the organ systems of the body work together to maintain homeostasis of the organism. If homeostasis fails, death or disease may result.
Organ systems are made up of multiple organs that work together to maintain homeostasis in an animal or multicellular animals. In animals, organ systems are seen, which coordinate to form an organism.
What is an organ system?Multicellular animals are made up of multiple cells, and these cells work together to make a tissue. All the cells in a tissue have a single function, such as epithelial tissue or nervous tissue; these tissues form the organs. An example is the stomach, which is made up of different types of tissue such as longitudinal smooth muscle, circular smooth muscle, etc.
These organs collaborate to form organ systems like the digestive system, which includes the stomach, small intestine, pancreas, liver. Organs such as the stomach digest food in the organ system, and the small intestine aids in the process by allowing it to absorb into the blood along with digestion. Organ systems are interdependent, such as the digestive system, which is dependent on the nervous system, the circulatory system, and so on.
hence Organ systems are made up of multiple organs that work together to maintain homeostasis.

How has the development of a pine and then a hardwood forest affected populations of shrubs?
A The development of the two types of forests has negatively affected populations of shrubs by decreasing the amount of pollinators in the area.
B The development of the two types of forests has positively affected populations of shrubs by increasing the amount of water available to shrubs.
С The development of the two types of forests has negatively affected populations of shrubs by decreasing the amount of space available to shrubs.
D The development of the two types of forests has positively affected populations of shrubs by increasing the amount of sunlight in the area.
Answer: Option C.
The development of the two types of forest has negatively affected the populations of shrubs by decreasing the amount of space available for shrubs
Explanation:
The development of the two types of forest has negatively affected the populations of shrubs by decreasing the amount of space available for shrubs because pine and hardwood are huge trees bigger than shrubs and occupy space. As they occupy space the received most of the sunlight, their roots is very extensive and draw water and nutrients from the soil which makes these resources not very much available for shrubs and hence it drastically affected the populations of shrubs. Because of their heights, wideness and big leaves, little sunlight gets to shrubs and hence shrubs photosynthesis is reduced.
The removal of one seral stage to another is called ecological succession.
The place which is used by the shrubs is now used by the tree and give the competition for the land. The development of the two types of forest has negatively affected the populations of shrubs by decreasing the amount of space available for shrubs.

Which abiotic factors would you expect to influence the growth of trees in the mountains?
Number of deer and insects
Types of trees and plants
Rainfall and the location on the mountain
Predator and prey population
Answer:
Rainfall and the location on the mountain
Explanation:
This is the answer because:
Rainfall highly helps the trees on the mountains grow. The location of a tree also matters a lot because it has to be in a spot where it can reach sunlight and lots of rain.
Therefore, the answer is Rainfall and the location on the mountain.

In an experiment, 1000 rodents were released into a light brown sandy area where no rodents previously existed. The rodents' fur color was either brown, black, or tan. There was a known predator of the rodents in the same area. After several generations, what fur color frequency would a researcher expect to see?
Answer:
It is expected that rodents with brown color have more chances to increase their frequency in the population
Explanation:
The cryptic coloration (or camouflage), is an adaptation that organisms have developed to disguise their appearance, thereby blending in with the surrounding environment. The cryptic coloration is used by organisms as a strategy to hide their identity, movement, and location from their predators. In this case, it is expected that organisms with the same color of the surrounding environment would be the best to be selected by natural selection, i.e., these organisms would have more chances to survive and to reproduce.
When does species richness increase at the fastest rate? Why is this possible?
Explanation:
As temperature increases, species richness tends to increase up to a maximum, beyond which water deficits then begin to depress richness
As temperature of the waterbody increases, the species richness tends to increase up to a maximum level, beyond this value water deficits which begins to depress the species richness.
What is Species Richness?Species richness is the number of different species present within a defined region. Species richness is commonly described by an index known as the Shannon's index 'H'.
Temperature has an important influence on the distribution of organisms in an area because it determines the physical state of the water body. Most organisms cannot live in conditions when the temperature remains below 0°C or above 45°C. The organisms cannot adapt to these extreme temperature ranges.
Temperature has been shown to increase the species interactions by increasing attack rate on species.

Suppose a human blood cell containing a 0.9 percent solute concentration were put into a container of 0 percent solute solution (i.E., distilled water). Would the blood cell get bigger or smaller? Why? In your explanation, you must tell me which area has the hypotonic solution (inside the blood cell or outside the blood cell), which area has the hypertonic solution (inside the blood cell or outside the blood cell), and which direction the water would be moving (into the cell or out of the cell).
Answer and explanation:
If a human blood cell with a 0.9% solute concentration were to be put into a container of 0% solute solution, the cell would get BIGGER.
The cell contains a more concentrated solution than the solution in the container. The difference in concentration would produce an osmotic gradient that would cause water from the container to get inside the cell to even the concentrations - this is going to make the cell much bigger because the entering water would bloat the cell.
In this example, the solution in the container is hypotonic in relation to the cell, while the solution inside the cell is hypertonic in relation to the solution in the container. This is why the water will be moving from outside of the cell to the inside of the cell.

Budding. Organisms reproduce by splitting off new individuals from existing ones, resulting in genetically identical parent and daughter organisms.
What do you mean budding?Budding is an asexual mode of organism formation. A new organism is formed from a small part of the parent's body during this process. A newly formed bud separates to form a new organism. The newly formed organism remains attached as it grows.To create an advantageous variety (cultivar) and rootstock combination, a single bud from a desirable plant is inserted into an opening in the bark of a compatible rootstock.Budding, also known as bud grafting, is a type of vegetative or clonal plant propagation that produces an exact replica of the parent plant. Chip budding and T budding are two slightly different methods of budding.To learn more about : Budding
