Predict what would happen to other organisms in an ecosystem in which all the decomposers went extinct?
Answer:
the other organism when they died with would not able to be decompose the they dead bodies would be left to rot . And then they food cycle would not be able to grow .In short food chain would disssolve
Explanation:
When organisms die, decomposers break down the dead bodies and the nitrogen is released and another type of bacteria breaks it down into gaseous nitrogen. Without decomposers and other types of bacteria, the nitrogen cycle would not be maintained. Plants would die off and the food chain would dissolve. As plant are primary producers

why farmers are manuring at the roots of the plant
Answer:healthy plants
Explanation:the farmers use raw manure on their fields because it is an excellent source of nitrogen (N), phosphorus (P) and potassium (K), which are all nutrients necessary for plants to grow and thrive.
Answer:
The reason why farmers put manure at the roots of the plants is because that is how most of the nutrition is taking up into the plant. Most of the minerals in the earth are absorbed into the plant for usage by the roots which is why the manure would be placed where the roots are. However, it's important to not put too much because that can actually cause the roots to get burned because there is too much minerals so it's important to keep a balance.
n this experiment the bag contains a hypertonic solution (sucrose), while the beaker only contains water. If you leave the bag inside of the beaker for approximately 45 minutes; the movement of water will occur from the ________ to the _________.
The water will move from beaker to the bag of sucrose due to concentration difference.
In which direction the water will move?The movement of water will occur from the beaker to the bag because the concentration of water is lower in the bag and higher in the beaker. So due to the process of diffusion, the water will move from the higher concentration region to lower concentration region.
So we can conclude that the water will move from beaker to the bag of sucrose due to concentration difference.

What does it mean that Oxygen and Water can exist in a gas state but at vastly different temperatures?
Answer: Water molecules are strongly attracted to each other, so they remain condensed (that is, a liquid, and not a gas) at higher temperatures. Dihydrogen and dioxygen have no strong attractive forces to hold the molecules together, so they exist as gases at room temperature and pressure (that is, in our everyday lives).
Explanation:
Typical gram-negative bacteria are more impervious to the action of antimicrobial chemicals than are gram-positives because gram-negatives have a(n)
As gram-negative bacteria have an extra layer of cell wall therefore it is less sensitive towards antimicrobial chemicals than gram-positive bacteria.
Why gram-positives are less impervious to the action of antimicrobial chemicals?Gram-positive bacterial cell wall is made up of only the peptidoglycan layer and it does not have an extra barrier that protects it from some antimicrobial chemicals.
Gram-negative bacteria have two layers of cell wall peptidoglycan layer and a lipopolysaccharide layer.
Thus, gram-negative bacteria have an extra layer of cell wall.

1. A 42,000 kg train car travelling at 10 m/s toward a stationary train car with a mass of 40,000 kg. After collision, the two sticked and moved together with the same speed. Solve for the final speed of the combined object after collision and identify their direction.
Given,
A 42,000 kg train car travelling at 10 m/s toward a stationary train car with a mass of 40,000 kg.
What is momentum?Momentum is a product of the mass of a particle and its velocity. Momentum is a vector quantity which means it has both magnitude and direction. Its formula = mass × velocity.
Solve for momentum:
M= (42,000kg)(40,000kg) / (10m/s)
M = 42,000 kilograms - 40,000 kilograms
M = 2,000kg
M = 2,000 kg ÷ 10m/s
= 200m/s
-Thus they collison at the same speed of 200m/s.

This is how a SIM medium looks after 24 hours and the addition of indole reagent. Is the unknown bacterium positive or negative for H2S production, indole production, and motility
In the test tube pink colour shows that it is indole positive and H2S positive bacteria and it is non motile.
What is the indole positive?Within seconds of introducing the reagent, a pink color appears in the reagent layer on top of the agar deep, indicating a positive indole test. The reagent layer will stay yellow or slightly hazy if the culture is indole negative.
When an organism converts sulfur to hydrogen sulfide, the hydrogen sulfide reacts with iron to generate ferric sulfide, a black precipitate. The presence of blackening in the medium suggests a reduction in sulfur, which is a +ve sign.
