Jenny brings home a plant with an internal concentration of 25g/ml. She puts the plant in her aquarium and fills the aquarium with water from the tap.
The plant will swell and possibly burst if the cell walls are weak.
B
The plant will wilt and possibly break apart if the cell membranes are weak.
C
The plant will thrive in a new type of environment.
D
The plant will become a creeping vine and grow out of the aquarium.
The plant will swell and possibly burst if the cell walls are weak. So, the correct option is A.
What is Cell wall?A cell wall is an external structural layer that surrounds some types of cells. It may be hard, flexible, or occasionally rigid. It serves as a filtration system as well as structural protection and support for the cell. The cell wall composition varies according to the organism which is permeable in nature
The cell wall isolates the inner elements from the surrounding environment. The cell as well as its organelles are also development in the context, support, and protection by it. But only eukaryotic plants, fungi, and a few prokaryotic creatures have this cellular component. If the plant's cell walls are insufficient in the case above, it will enlarge and possibly burst.
Therefore, the correct option is A.

The diagram below represents levels of organization in living things. Which term would best represent X?
A. Stomach
B. Human
C. Tissue
D. Chloroplasts
The correct answer is C. Tissue
Explanation:
In the diagram, x is between organ and cell level. This implies this level of organization is smaller than an organ but no as small as one cell. In this context, the most suitable term to add to this level is a tissue because these are structures composed of specialized cells, which shows this level encloses cells. Also, a group of tissues forms an organ; this implies the organ is the level that follows the tissue. Examples of this include muscle tissue composed of muscle cells and that is part of organs including the heart.
The term that would best represent X would be tissue.
The simplest level of organization of living things is the cell followed by tissue, organ, organ system, and then the organism itself.

The amount of carbon on this Earth does not change. However, where the carbon is located does change. These locations are referred to as sources and sinks. Sources are areas that add carbon to the atmosphere and sinks are areas that remove carbon from the atmosphere. The sources and the sinks are important to the regulation of green house gasses. Carbon dioxide is one of several green house gasses that keep our planet warm. Too few greenhouse gases in the atmosphere would allow our planet to freeze, too many cause our planet to warm up too much. In the space below describe how humans are disrupting the natural cycle and contributing to the green house gasses in the atmosphere.
Answer:
In this stylized representation of the human-intensified greenhouse effect, human activities, predominantly the burning of fossil fuels (coal, oil, and gas), are increasing levels of carbon dioxide and other heat-trapping gases, increasing the natural greenhouse effect and thus Earth’s temperature.
Explanation:
One problem that was brought about by human action and is definitely affecting the hydrosphere globally is that of the greenhouse gases (so called because of their heat-trapping “greenhouse” properties) emitted to the atmosphere. Of the greenhouse gases released by anthropogenic activities, carbon dioxide has received much attention.

Answer:
Equation
Explanation:
the last word is Equation
Considering the definition of chemical reaction and chemical equation, A chemical reaction can be mathematically represented by showing the required amount of products and resulting reaction components using a chemical equation.
Chemical reactionA chemical reaction consists of the formation of new substances (products) from others (reagents). In this process bonds of the reactants are broken and new ones are formed in the products.
In other words, a chemical reaction occurs when the substances participating in it are transformed into different ones. The mass of the participating substances is the same before and after the reaction, that is, it is conserved because only a rearrangement takes place between the atoms of the reactants, which break and form new bonds.
Chemical equationChemical reactions are represented by chemical equations. In them, the reactants are determined, the products are predicted, and the proportions of the substances that participate in the reaction are indicated.
SummaryA chemical reaction can be mathematically represented by showing the required amount of products and resulting reaction components using a chemical equation.

LH₂O
Answer:
[tex]\boxed {\tt B. \ Isotonic}[/tex]
Explanation:
We can see that the H₂O or water is leaving the cell and entering the cell at the same rate.
An isotonic solution has the same amount of solute outside the cell and solution inside cell. Therefore, when the water moves across the membrane, the water inside the red blood cell does not change.
Therefore, the best answer choice is B. Isotonic

knowing what you know about how a substance travels in diffusion in order for carbon dioxide to leave the blood and enter the alveoli there would be higher or lower concentration of carbon dioxide
Answer:
CO2 moves down its concentration gradient by simple diffusion. Therefore, CO2 would have to be high in the blood, and low in the alveoli for simple diffusion to happen, this would be done by passive diffusion and thus, simple diffusion.
Remember that in simple diffusion you go from an area of a high concentrated solute towards an area of low concentrated solute.
Explain why populations tend not to continue to increase exponentially in an environment: 2. Explain what is meant by environmental resistance: 3. (a) Explain what is meant by carrying capacity: (b) Explain the importance of carrying capacity to the growth and maintenance of population numbers: 4. Species that expand into a new area, such as rabbits did in areas of Australia, typically show a period of rapid population growth followed by a slowing of population growth as density dependent factors become more important and the population settles around a level that can be supported by the carrying capacity of the environment. (a) Explain why a newly introduced consumer (e.g. rabbit) would initially exhibit a period of exponential population growth: (b) Describe a likely outcome for a rabbit population after the initial rapid increase had slowed: 5. Describe the effect that introduced grazing species might have on the carrying capacity
Answer and Explanation
Explain why populations tend not to continue to increase exponentially in an environment: The exponential growth model is based on unlimited resource availability which means that there is no effect depending on density. There is no competition for resources. Natality and mortality rate do not depend on density. There is a constant growth rate per capita and it is proportional to the population size. A population that exhibits exponential growth model increases in proportion to its size. In the Logistic growth model, the population growth depends on density, the natality and mortality rate depends on the population size, which means that there is no independence between population growth and population density.
When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population's per capita growth rate decreases as population size increases. The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
Explain what is meant by environmental resistance: It refers to the limiting factors. There are factors and conditions that regulate the population growth, that might be biotic or abiotic, and that avoid the over-growth of a population in a certain space. It results in a natural equilibrium of its biotic potential.
Explain what is meant by carrying capacity: The carrying capacity K is the maximum point delimited by available resources, such as food or space.
K is a constant that coincides with the size of the population at the equilibrium point when the natality rate and the mortality rate get qual to each other.
Explain the importance of carrying capacity to the growth and maintenance of population numbers: If the population size, N, is inferior to K (N<K) the population can still grow. When N approximates to K, the population´s growth speed decreases. When N=K, the population reaches equilibrium, and when N is superior to K (N>K) the population must decrease in size because there are not enough resources to maintain that size.
Explain why a newly introduced consumer (e.g. rabbit) would initially exhibit a period of exponential population growth: The example of the rabbit is a case of invasion. Biologic Invasions refer to new species that disperse and establish in a new area far or out of their original distribution range. Once established, these species expand their distribution from the first invaded spot and overgrows. Once stablished, they expand. In the new area, they have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-, and these factors favor their overgrowth and consequently uncontrolled expansion. At this point, the population is exhibiting exponential growth. They have enough food available, they might not have predators, they do not have enough competitors for food or space, and if they do they are adapted to live under harder conditions so they are able to compete. The new species is not suffering from the effects of limiting factors yet.
Describe a likely outcome for a rabbit population after the initial rapid increase had slowed: There are some typical steps in an invasion process:
1) Introduction or dispersion to the new area,
2) Naturalization. The new species establishes in the new area. It can grow, reproduce and make use of resources.
3) Overgrowth and uncontrolled expansion. Exponential growth
4) Interaction with other species. At this point, they compete for limiting factors such as food or space. Their population is big enough to be affected by resource availability and by other species that interact with them. The invasive species reach the point in the curve where they stabilize.
5) Stabilization. They reach an equilibrium point.
Describe the effect that introduced grazing species might have on the carrying capacity. The introduced species expand fast and consume too many resources. Available resources, such as food or space, decrease.
The populations tend not to continue to increase exponentially in an environment due to various environmental factors which restricts or limits its growth.
Environmental resistance refers to environmental factors that restrict the biotic potential of an organism or limit the increase in population. Carrying capacity refers to average population of specie's size in a particular habitat. The importance of carrying capacity to the growth and maintenance of population number because carrying capacity provides resources to a specific population of organisms.
Newly introduced consumer (e.g. rabbit) would initially exhibit a period of exponential population growth because of no predator present in the environment. The introduction of predators which feeds on rabbit is the outcome for a rabbit population after the initial rapid increase had slowed
There is a great effect of introduced grazing species might have on the carrying capacity because more introduced grazing species removes all the vegetation present in that environment which leads to imbalance of ecosystem.
