Give two examples of how abiotic factors are influenced by biotic factors.
Answer:
Ecosystems are influenced by both biotic and abiotic factors. Biotic factors include animals, plants, fungi, bacteria, and protists. Some examples of abiotic factors are water, soil, air, sunlight, temperature, and minerals.
The utilization of resources by the living organisms which are biotic factors influence the abiotic factors, which are the resources.
What are biotic and abiotic factors?The term biotic factors means the factors of components of the ecosystem which are living. Therefore it can be said that all living organisms present on earth are biotic components.
Examples of biotic factors are plants, animals, human beings, decomposers, yeast, insects, etc. All of these factors or biotic components interact with each other for the development of new generations. That means reproducing new organisms to maintain the food chain.
The components of the ecosystem that are non-living are termed abiotic factors. They play a very important role in the maintenance of ecosystems. The interaction of the biotic and abiotic factors is important for the stability of the ecosystem.
Some examples of abiotic factors are air, weather, water, temperature, humidity, altitude, pH, level of soil, types of soil and more, water flow rate, water depth, etc.
Therefore, the use of water and land by living organisms are some of the many examples by which biotic factors affect abiotic factors.

3.)Dependent is water
Independent is mass
4.) Indepent is the whole scenario
Dependent is the speed and how it affects the cars.
5.) Independent is the wet or dry enviroment
Dependent is the time spent
Explanation:
Dependent variable is weight and Independent variable is growth hormones.2.) Independent variable is mosquito repellent and Dependent variable is number of bites.
What is Dependent variable?The dependent variable is the variable that is being measured or tested. For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores since that is what is being measured.
This is different than the independent variable in an experiment, which is a variable that stands on its own. The independent variable (tutoring) doesn't change based on other variables, but the dependent variable (test scores) may.
One way to help identify the dependent variable is to remember that it depends on the independent variable. When researchers make changes to the independent variable, they then measure any resulting changes to the dependent variable.
Therefore, Dependent variable is weight and Independent variable is growth hormones.2.) Independent variable is mosquito repellent and Dependent variable is number of bites.

SOLVE Suppose you are helping scientists conduct a study of a population of Clear Lake
hitch, which is a fish species that lives in Californian lakes. The scientists initially capture
80 hitch from a lake and tag all of them. After 30 days, they capture 100 hitch and count
20 tags. Use the space below to calculate the estimated number of hitch in the lake. Show
your work
Answer:
400
Explanation:
Scientists tagged 80 hitch. When they capture 100 hitch, 20 are tagged. In order to estimate the population of hitch, we can assume that this proportion is consistent.
This means for every 20 tagged hitch, there are 80 untagged. We know there are 80 tagged total, so we need to multiply 20 by 4 to get it to 80. To keep the proportion equal we also need to multiply the untagged hitch.
[tex]\frac{20}{80}[/tex] * [tex]\frac{4}{4}[/tex] = [tex]\frac{80}{320}[/tex]
Still following the proportion, we have 80 tagged hitch and 320 untagged hitch. 80 + 320 = 400 hitch total.

How do polar molecules form Hydrogen Bonds?
What determines whether a compound will dissolve in water?
How do polar molecules differ from non-polar molecules?
Describe an example of cohesion or adhesion that you might observe in your daily life.
Answer:
How do polar molecules form hydrogen bonds?
Polar molecules form hydrogen bonds when hydrogen is bonded to Nitrogen, Oxygen, or Fiorina. This is because these atoms are highly electro-negative meaning they often have the electron they have sharing with hydrogen. Hydrogen atoms bonded with these atoms are attracted to the partial negative charge of similar atoms.
What determines whether a compound will dissolve in water?
Water is a polar molecule and transmits a partial positive and negative change between its atoms, enabling it to easily dissolve other ions and polar molecules.
How do polar molecules differ from non-polar molecules?
Polar molecules have charged regions due to unequal sharing of electrons/ Nonpolar molecules do not have charged regions because electrons are shared more equally. The charge differences tend to keep the molecules separate.
Describe an example of cohesion or adhesion that you might observe in your daily life.
Cohesion: water beading on a surface.
Adhesion: water sticking to the side of glass.
