Answer: Congestive Heart Failure
 Congestive heart failure is the inability of the heart muscle to pump blood at a life-sustaining rate. Such conditions as high blood pressure and narrowed arteries of the heart leave your heart stiff to pump efficiently.

There are lots of signs of heart failure which you should not ignore. Better see your doctor and seek emergency treatment if you experience chest pain, fainting, rapid or irregular heartbeat coupled with shortness of breath.

Answer:

how changes in biodiversity impact an ecosystem

Explanation:

Water hyacinth is a free-floating perennial aquatic plant. This plant is native to tropical and sub-tropical South America. As an invasive species, when it grows in the new environment causes severe ecological or economic harm. By growing where it not native, it can spread extremely fast, blanketing a water surface in a very short period of time. It can limit boat traffic, swimming, and fishing, and it can deprive native plants and animals of sunlight and oxygen, thus reducing the local biodiversity.

This is how an ecosystem effects biodiversity impact. When a biological species grows in the new environment, It can affect the biodiversity or environment that can affect the biological species.

Aminosyn is an amino acid often times used in tpn orders to provide protein for cellular repair and growth. a physician writes a

love history [14]

I think theres a few methods to do it, but this is probably the most efficient.

Physician has prescribed 2.5% of 500ml
Actual amount of Aminosyn in this prescription is
500*0.025= 12.5ml of Aminosin

Therefore you need to ensure when you pour your solution of the 8.5% Aminosyn, it has 12.5 ml of Aminosyn.

To work out how much 8.5% Aminosyn you should pour, you must think of the 12.5ml as 8.5%

Therefore 1% = 12.5/8.5= 1.470588

Therefore the amount of 8.5% solution you need to pour is 100* 1.470588= 147.1ml

Then make up the rest(352.9ml) by adding distilled water. You now have 500ml of 2.5% aminosyn.

emily wants to know how green, blue and red color light affects plant growth compared to natural light. (Hint: what light affect

MArishka [77]

Red and blue colored lights are most effective for plant growth.

Plant Growth is the dependent variable and light color is the independent variable. The rest are control variables.

A Control variable is the part of the experiment that we keep the same throughout all of the test subjects. An independent variable does not depend on other variables and a dependent variable does.

Allow me to explain. When we perform an experiment, many factors that can change the results, For this reason, it is common practice to keep many of them the same for all test subjects (In this case for all of the plants). This way we know that if changes are measured, they were not caused by these variables. These are what we call control variables.

An independent variable does not depend on other variables to remain the same. For example, the species of plant would be an independent variable, given that a plant cannot change its species because of other factors.

A dependent variable does change according to other variables and is often what we try to measure. For this example given, the dependent variable is how much the plant will grow with each colored light.

Knowing that plants rely on light to produce the energy needed to grow, we can hypothesize that applying different colors of light will have an effect on plant growth. To test this, we can create an experiment where we use:

Soil
amount of water
amount of light
species of plant
length of experiment

As control variables.

One group of plants will have blue light, another green, and another red. We can identify the color of light as an independent variable.

Since what we seek to measure is plant growth, we identify this as our dependent variable and measure it for each plant after a set amount of time, to compare results.

With this, you can confidently identify the control, dependent, and independent variables and how to use them in your experiment.
