Meg researched the biodiversity in four water ecosystems. Which ecosystem likely has the highest biodiversity?
The ecosystem that likely has the highest biodiversity is a small pond with a variety of plant and animal species. The correct option is A.
The choice with the maximum biodiversity is probably a small pond with a wide range of plant and animal species.
Ponds frequently have a variety of ecosystems that offer a variety of habitats for various creatures. several plant species are present, and water is readily available, which creates niches for several animal species as well.
As opposed to the rich environment seen in a little pond, the other possibilities, such as a huge river with a modest number of species, a stagnant lake with few species, or a fast-flowing stream with few species, reflect lesser levels of biodiversity.
Thus, the correct option is A.

Which sentences describe the logistic growth model?
There are three different phases of the S-shaped curve. At first, growth is exponential because Individuals are few and resources are plenty.
This growth model occurs in a situation where resources are plenty and individuals are few to consume the resources. Population growth
decreases as resources become limited. When a population size reaches the carrying capacity of its environment, the population growth slows
down or stops completely. The model looks like a j-curve.
Reset
Next
Answer:
When a population size reaches the carrying capacity of its environment, the population growth slows down or stops completely.
Explanation:
This is true for the S-curve, but not the J-curve
The logistic growth model depicts the carrying capacity at its maximum level. It is best described as " a population size reaches the carrying capacity of its environment, the population growth slows down or stops completely."
What is logistic growth?Logistic growth has been defined by the growth of the population in ana areas that have to reach their carrying capacity. The growth curve has been limited by food and water resources (environmental factors).
Unlike the exponential curve model, it is an S-shaped model that increases first and then shows a slower growth rate and eventually termination of the population growth due to mortality and natality rate.
It is also called sigmoidal growth where the population size shows an increase at first till the population stabilizes. It is not the same for the J curve as the population does not slow down at the carrying capacity.
Therefore, the affirmation of the slow population size at the carrying capacity is true for the logistical curve (S-shaped) but not for the J-curved model.

What forensic investigator studying a tool mark?An item with a tool mark may occasionally be gathered as proof (e.g., a doorknob bearing marks from pliers is removed from the door and placed into evidence).
The examiner will use the comparison microscope to compare examine tool marks in a manner similar to how they are examined for bullets and cartridge cases.
The toolmark examiner will contrast the test mark's microscopic characteristics with the tool mark on the supporting documentation.
Therefore, Even if it is decided not to cast the tool markings, minor crime scenes should nonetheless have their tool marks photographed.

It is important to survival that both unicellular and multicellular organisms are able to maintain homeostasis. Which is not example of organisms maintain homeostasis?
A.cells always stay the same.
B.cell division allows or organisms to grow and repair damaged parts.
C.food is made during photosynthesis, and energy is produced from during respiration.
D.materials move into and out of the cells though the cell membrane.
Answer:
A.cells always stay the same.
Explanation:
Homeostasis is the ability of an organism to maintain a stable internal state despite changes in external conditions. The process of homeostasis is important to the survival of both unicellular and multicellular organisms, as mentioned in this question.
Examples of homeostatic process undergone by organisms include:
- Cell division, which allows organisms to grow and repair their damaged parts.
- Making of food during photosynthesis, and production of energy during cellular respiration. This two processes are necessary for the survival of organisms as one produces food and the other synthesizes energy.
- Movement of materials into and out of the cells though the cell membrane, which is required to bring in needed substances and remove unwanted ones.
However, a cell staying the same does not depict any HOMEOSTATIC PROCESS.
Use scientific reasoning and the food web to explain why, in general, it makes sense that the lion population is taking longer to recover than the herbivore populations.
Answer:
Explanation:
Herbivores are able to come back easily when they are search for food because their are more than enough food for them to prey on while in lion population, their main feed also take longer period to be produced since they also feed on animal that take time to give birth such as zebras, so they go for other smaller organisms such as waterbucks which take them more time to be completely feeds on to gain required energy.

Answer:
conduction and radiation.
Explanation:
I looked it up on quizlet
hope this helped
The ice-cream melts after hitting the sidewalk due to the processes of conduction and radiation.
What is conduction?
Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules .
When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:
1) heat conduction
2) electrical conduction
3)sound conduction

Answer:
Independent variable: CALCULATOR
dependent variable: SPEED AT SOLVING LONG DIVISION PROBLEMS
controlled variable: SAME GRADES, SAME PROBLEM
Explanation:
Independent variable is the variable that is changed or manipulated by the experimenter in an experiment. In this experiment, the independent variable is the CALCULATOR, which was changed in the experiment.
Dependent variable is the variable that is measured in the experiment. It is the variable that responds to changes made to the independent variable. In this experiment, the dependent variable is the SPEED AT SOLVING LONG DIVISION PROBLEMS.
Controlled variable or constants are variables that are kept unchanged for all groups throughout the experiment. In this experiment, the controlled variables are: SAME GRADES, SAME DIVISION PROBLEM

Describe the path of a nitrogen atom through four parts of the nitrogen cycle. Be sure to explain the processes involved in the transfers. Note when a form of nitrogen is available to plants.
Answer: One of the ways the path of a nitrogen atom begins is as a part of an ammonium ion. A plant takes up the ion and uses it to make an organic molecule through assimilation. The organic molecule falls back to the ground as part of a leaf. The leaf is decomposed by bacteria, and it is converted back to ammonium by ammonification. The ammonium ion is then converted to nitrite by nitrifying bacteria through nitrification.
Explanation: That's what popped up after I hit submit so that's the answer hope this hepls.
Answer:
A nitrogen atom can start its journey as part of an ammonium ion, for example. Through assimilation, a plant absorbs the ion and uses it to create an organic molecule. As part of a leaf, the organic molecule returns to the earth. Bacteria breakdown the leaf, which is then turned back to ammonium by ammonification. Through nitrification, the ammonium ion is transformed to nitrite by nitrifying bacteria.
