The secound week my water was more of a green color and not as much brownish clear. There was also some green stuff growing which i think that was alge.The third week my water was all the way green and i noticed there was some stuff floating in the water but i dint see any living organisms. There was also more alge in it than last time.

An image of a wooly mammoth and a mastodon is shown here. Analyze the similarities and differences between these species and
present-day elephants. Evaluate the statements below and select the one(s) that accurately describe the evolution of these
species. Select ALL that apply.
Several factors were important for the extinction of mammoths to mastodons, and natural selection of the elephant, mainly the ecosystem they lived in and the search for food.
What are the differences between the mammoth and the elephant?The mammoth is an animal that was once extinct and belonged to the genus Mammuthus and the family Elephantidae which included the proboscidians. Elephants differ from mammoths in that mammoths had their bodies covered with hair. Also, elephants are slightly smaller than mammoths.
What are the differences between the mastodon and the elephant?Both were herbivores, but the mastodons had conical-shaped teeth designed to crush leaves and branches more easily. Mammoths had rough molars, allowing them to cut through vegetation and graze like modern elephants.
Whit this information, we can conclude that several factors were important for the extinction of mammoths to mastodons, and natural selection of the elephant, mainly the ecosystem they lived in and the search for food.

explain why norepinephrine requires a protein receptor to exert its effects.
Answer:
I'm going off the top of my head for this one, and this is an educated guess, so check it if you would like to. When the norepinephrine binds to a protein, then the protein relays the info to the cells that are required to do the specific action. This is why we feel a sense of stress, elevated heart rates, or high alertness.

Answer:
Soil living organisms compromise from mammals (such as rats) to micro organisms (such as nematodes and protozoa). Soil organisms help in the modification of soil, and also in the decomposition of organic matter. However they can also pose as a treat to to some crops, as they are responsible for some plant diseases.

When living organisms breathe they give out carbon dioxide gas as a waste product. Carbon dioxide gas can be detected (identified) using a carbon dioxide indicator solution called bromothymol blue. To find out if there are living organisms present in the four different levels of soil takenfrom the deciduous forest.

How to do a dichotomous key
Answer: I hope this helps you! :3
Explanation:
Step 1: List down the characteristics
Pay attention to the specimens you are trying to identify with your dichotomous key. List down the characteristics that you can notice. For example, say you are trying to classify a group of animals. You may notice that some have feathers whereas others have legs, or some have long tails and others don’t.
Step 2: Organize the characteristics in order
When creating your dichotomous key, you need to start with the most general characteristics first, before moving to the more specific ones. So it helps to have identified the more obvious and less obvious contrasting characteristics among the specimen before creating your dichotomous key.
Step 3: Divide the specimens
You can use statements (i.e. has feathers and no feathers) or questions (does it have feathers?) to divide your specimens into two groups. The first differentiation should be made on the most general characteristic.
Step 4: Divide the specimen even further
Based on the next contrasting characteristic, divide the specimen further. For example, first, you may have grouped your animals as have feathers and have no feathers, in which case the ones with feathers can be categorized as birds while you can further subdivide the ones that have no feathers as having fur and having no fur. Continue to subdivide your specimen by asking enough questions until you have identified and named all of them.
Step 5: Draw a dichotomous key diagram
You can either create a text-based dichotomous key or a graphical one where you can even use images of the specimen you are trying to identify. Here you can use a tree diagram or a flowchart as in the examples below.
Step 6: Test it out
Once you have completed your dichotomous key, test it out to see if it works. Focus on the specimen you are trying to identify and go through the questions in your dichotomous tree to see if you get it identified at the end. If you think the questions in your dichotomous key needs to be rearranged, make the necessary adjustments.

A space where water from various sources drains is called a watershed. The water from streams and rivers gets drained to a common outlet. The answer should be blank 1 factors, blank 2 human and blank 3 is food web.
What is a watershed?A watershed is a section of drainage basin or "sheds" water into a particular body of water.
A watershed exists for every body of water. Rainfall and snowmelt are channeled into streams and rivers by watersheds.
These smaller bodies of water drain into larger bodies of water, such as lakes, bays, and oceans.
Abiotic and biotic factors enter and flow through the watershed. These can include plants, small microorganisms, soil, small rocks, and so on.
Human impacts have an impact on the food chain because activities such as deforestation, industrial emissions, and fuel combustion cause environmental changes that harm animals and plants in the ecosystem.
The food web depicts the energy flow in an ecosystem from producers to consumers and represents how energy is passed from plants to consumers as well as their interdependence.
Thus, it can be concluded that the blanks are factors, human and food web respectively.

Why is an ecosystem with higher levels of biodiversity more stable than an ecosystem with lower levels of biodiversity?
O because species are more adaptable
O because they are better able to withstand stresses like disease or climate change
because changes affect every species the same way
because species are constantly replacing one another
An ecosystem with higher levels of biodiversity is more stable than another with lower levels because they are better able to withstand stresses like disease or climate change.
What is biodiversity?The term biodiversity refers to all of the variations (both genetic and phenotypic) in a given population.
Biodiversity is a fundamental subject to maintaining the equilibrium (homeostasis) of the whole ecosystem.
