Write a hypothesis about the worms and lima
bean plants. Be sure to answer the lab
question, “How can the presence of one
species benefit another in the same
ecosystem?"
Hypothesis: If plants are grown in soil
containing worms, then...
because ..
Answer: If plants grow in soil containing worms, then plant growth will be greater, because worms help decompose organic matter
Explanation: just did it and got it right
If plants are grown in soil containing worms, then they will develop strong and healthy because worms provide the necessary elements to the soil by degrading organic matter.
What is a hypothesis?
A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact.
A hypothesis must express what is expected to occur in a perfectly comprehensive manner. There must be a logical relation between variables. It must be objective.
There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.
In this example we need to consider how the presence of the worms affect the bean plants development.
The variables are the presence of worms and the plants' development.
Hypothesis:
If plants are grown in soil containing worms, then they will develop strong and healthy because worms provide the necessary elements to the soil by degrading organic matter.

Which is not an element of weather that is measured and analyzed to make accurate forecasts? a: relative humidity/dew point b: time c: cloud cover/visibility d: wind direction
Answer:
b: time
Explanation:
When meteorologists need to make a forecast they analyze different measurements in order to accurately make a forecast, these include patterns of winds, pressure, pressure change, temperature, humidity, clouds, and hygrometers. From the answers provided the one measurement that is not used is time. Mainly due to the fact that weather does not depend on the time of day, and any type of weather can be present at any time if the right circumstances exist.
Answer:
Wind direction
Explanation:
Weather forecast is simply known to be a way of telling the people of how the weather condition of a particular place will be at a particular time. This usually shows whether the day or time will be rainy or sunny.
In this case, what is not normally considered in whether forecast is wind direction. While other factors are always ingredients of weather forecasting.
How can photosynthesis be related to cellular respiration?
-What's produced (made) by one is needed (the reactants) for the other.
-They both produce the same products.
-They both have the same reactants (need the same things).
-These two processes have nothing in common.
Answer:
These two processes are related because what's produced by one is needed for the other.
Explanation:
In photosynthesis, O2 and glucose are produced. Autotrophs (and heterotrophs too) use cellular respiration to make carbon dioxide and water from organic compounds - glucose - and oxygen; therefore, we can say that the glucose and oxygen are acting as reactants in the process of cellular respiration.
Photosynthesis can be related to cellular respiration because What's produced (made) by one is needed (the reactants) for the other.
What is photosynthesis and cellular respiration?Photosynthesis is a process by which plants produce oxygen and energy in the form of carbohydrates by combining sunlight, water, and carbon dioxide.Cellular respiration is a series of metabolic reactions and activities that occur within organisms' cells to transform chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP) and then release waste products (CO2).How are Photosynthesis and cellular respiration interrelated?A significant link exists between photosynthesis and cellular respiration. The reactants of one process are the products of another. It's worth noting that the equation for cellular respiration is the total opposite of the equation for photosynthesis:Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O2
Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O
Photosynthesis produces the glucose required for cellular respiration and the production of ATP. After that, the glucose is converted to carbon dioxide, which is subsequently used in photosynthesis. During photosynthesis, water is broken down to generate oxygen, but during cellular respiration, oxygen is mixed with hydrogen to form water. Cellular respiration requires oxygen produced by photosynthesis and releases carbon dioxide, whereas photosynthesis requires carbon dioxide and releases oxygen.

How do erosion and deposition work together to create a moraine?
Waves cause erosion along coastlines and deposit sand away from the shore.
Surface water in rivers causes erosion, carrying sediment that gets deposited near an ocean.
Glaciers cause erosion as they melt, carrying sediment that gets deposited in a thick layer.
Winds cause erosion by blowing around sand that gets deposited in large piles.
Answer:
Glaciers cause erosion as they melt, carrying sediment that gets deposited in a thick layer.
Explanation:
Glaciers are dynamic ice structures that change their size and shape as they grow and melt. Glaciers cause erosion as they melt, carrying sediment that gets deposited in a thick layer.
---------------------------------------
Glaciers have a high capability of soil denudation and erosion. They are capable of transporting many materials of varying sizes y drive them down the hills.
Remember that in the glacier's interior, there are melted ice streams that acquire a high velocity. They can move material from the base of the glacier and produce erosion.
The term moraine refers to the material deposition caused by glaciers. According to the glaciers' dynamics and the material deposited, there can be several types of moraines.
Fontal moraineBasal moraineEndoglacier moraineLateral moraineCentral moraineBasically, moraines types depend on how materials get deposited as the glacier melts, or stays stable, or gets closer to another glacier, etcetera.
Materials can get deposited when falling from the surface of the ice in different directions. Material can sink into the interior of the ice and get deposited from there. Material can be driven directly along the glacier's base, as internal streams carry them and the glacier melts.---------------------------

The population of frogs and mice would increase which would cause the population of grasshoppers to decrease. D. The population of frogs and mice would increase which would cause the population of grasshoppers to increase.
Answer: the population of frogs and mice would increase which would cause the population of grasshoppers to decrease
Explanation: I’m on the test right now and I’m looking at the web, the mice and frog get eaten by the snake, and the grasshopper get eaten by the frog and the mice, so if the mice and frog population increases the populating of the grasshopper would decrease :)
If snakes were removed from the food web, the population of frogs and mice would increase which would cause the population of grasshoppers to decrease.
Snakes predate on frogs and mice. Thus, if they are removed from the food chain, the population of frogs and mice would be less pressured and, therefore, thrive.
With the thriving population of frogs and mice comes the pressure on the population of grasshoppers. Frogs and some species of mice feed on grasshoppers.
Thus, if the population of frogs and mice thrives as a result of the absence of snakes, more grasshoppers will be eaten and the population of grasshoppers will decrease as a result.
