Some protozoans have special organelles called contractile vacuoles that continually eliminate excess water from the cell. The presence of these organelles tells you that the environment Group of answer choices is hypotonic to the protozoan. contains a higher concentration of solutes than the protozoan. is isotonic to the protozoan. is hypertonic to the protozoan.

Answers

Answer 1

Answer:

is hypertonic to the protozoan.

Explanation:

The presence of contractile vacuoles tells us that the environment  is hypertonic to the protozoan that contains a higher concentration of solutes in the outside environment than the protozoan. The water moves outside the cell if its concentration is higher inside the cell so due to diffusion and no need of extra water, the water removes by the contractile vacuole to the outside environment so we can say that the environment is is hypertonic to the protozoan.

help me ..it's a MCQ

Answers

Explanation:

I think your answer is D, and let me explain why.

Heat can denature proteins quickly because proteins have very specific temperatures at which they act best. If the temperature rises too high/falls too low with respect to that threshold, then that will cause the proteins to stop working properly and eventually die.

pH is also very important with how proteins work, and it's the same reason as heat. Proteins have a certain range of pH's that keep them healthy and working, but as soon as the pH changes dramatically outside of that range, the proteins will be quickly denatured.

And lastly, organic solvents can denature proteins as well (e.g. alcohol), which makes sense because they are solvents (a solvent is something that dissolves other substances). I'm not sure about the exact chemistry / biological responses behind it, but it's what would be expected of a solvent.

With all of this in mind, I think your answer should be D!

Why does the thermosphere increase in temperature as altitude increases?

Answers

Answer:

The thermosphere is the outer layer of the Earth's atmosphere, extending from about 53 miles to more than 370 miles above the surface. The temperature increases rapidly in this layer due to the absorption of huge amounts of incoming high energy solar radiation by atoms of nitrogen and oxygen.

Answers

Answer:

See the answers below

Explanation:

A) The mud in Amal's beaker will settle down at the bottom of the muddy water if left overnight with clear water occupying the surface. This is because the particles of mud are insoluble in water and will settle down at the bottom of the muddy water if left undisturbed for a while.

B) The process is called sedimentation. The settled mud particles are referred to as the sediments and the clear water at the top can be decanted off to separate the sediment from the water.

What are organic compounds?

Any of a wide area of chemical compounds in which one or many carbon atoms are covalently connected to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.

Carbides, carbonates, and cyanides are among the few carbon-containing compounds that are not classified as organic.

The main distinction between organic and inorganic compounds is that organic compounds always contain carbon, whereas most inorganic compounds do not.

Furthermore, almost all organic compounds contain carbon-hydrogen or C-H bonds.

Organic foods are grown without the use of synthetic pesticides, fertilizers, or herbicides.

Organic meat, eggs, and dairy products are derived from animals that have been fed natural feed and have not been given hormones or antibiotics.

Which greenhouse gas has an average lifetime in the atmosphere of a few weeks to thousands of years and is the largest contributor to climate change?

Answers

Answer:

Greenhouse gases from human activities are the most significant driver of observed climate change since the mid-20th century.1 The indicators in this chapter characterize emissions of the major greenhouse gases resulting from human activities, the concentrations of these gases in the atmosphere, and how emissions and concentrations have changed over time. When comparing emissions of different gases, these indicators use a concept called “global warming potential” to convert amounts of other gases into carbon dioxide equivalents.

Explanation:

Why does it matter?

As greenhouse gas emissions from human activities increase, they build up in the atmosphere and warm the climate, leading to many other changes around the world—in the atmosphere, on land, and in the oceans. The indicators in other chapters of this report illustrate many of these changes, which have both positive and negative effects on people, society, and the environment—including plants and animals. Because many of the major greenhouse gases stay in the atmosphere for tens to hundreds of years after being released, their warming effects on the climate persist over a long time and can therefore affect both present and future generations.
