Dead zones are areas along the coasts where rivers spill excess nutrients into the oceans. Microorganisms feed on these nutrient

s, which in turn causes them to use up all the ________ in the water and kill larger organisms like fish.
1. sediments
2. phosphorus
3. oxygen
4. nitrogen

1 answer:
Gnesinka [82]3 years ago
3 0

Answer:

3. oxygen

Explanation:

<em>Dead zones are hypoxic (lacking oxygen) water bodies</em> (oceans, lakes, rivers) where there is an increase in nutrients (generally nitrogen and phosphorous) that lead to an excessive population of algae that lowers oxygen levels. These conditions make life impossible in these areas, therefore, their name.

I hope you find this information useful and interesting! Good luck!

In neuroscience, depolarization is an "all or nothing" response; what does that
Tom [10]

Answer:

The correct answer is - The neuron's intracellular charge must get more positive to meet a certain  thresh hold in order to depolarize. If the neuron does not hit that threshold, then the  neuron will not fire

Explanation:

In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.

If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.

scientists believe the earth likely warmed between 0.65 celsius and 1.05 celsius with an average value of 0.85 celsius between y
scoray [572]

Answer:

The lower limit is 0.65°C

The upper limit is 1.05°C

the average is 0.85°C

The difference between the average and the lower limit is:

0.85°C - 0.65°C = 0.20°C

the difference between th average and the upper limit is:

0.85°C - 1.05°C = -0.20°C

Then we can write the change in temperature as:

T = 0.85°C ± 0.20°C

Now we want to find the error bar.

The error bar would be the total distance between the lowest value and the largest value.

Then the error bar is:

1.05°C - 0.65°C = 0.40°C

notice that the error bar is twice the error, which makes a lot of sense because the error (± 0.20°C) goes up and down.

Then the error bar in this measure has a magnitude of 0.40°C.

which type of molecule stores the main source of energy used by animals? a) lipids b) proteins c) glycogen d) starch
Flauer [41]

The correct answer is option C-glycogen

Glycogen is an immediate source of energy in animals. Glycogen is formed of small sub-units called glucose monomers. The process of formation of glycogen is called glycogenesis.  

Glycogen is animal equivalent to starch.  

When body need energy, the stored glycogen breaks down into small monomers called glucose and provide energy to the cell.  

The excessive amount of glycogen is stored in muscles and liver.
