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.
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?
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.

punto de vista sobre la ley de mendel
Answer:
Las leyes de Mendel son leyes que describen la herencia de rasgos hereditarios. Las leyes forman la base de la genética clásica. Asumen que cada individuo posee dos alelos para el mismo rasgo y los recibe al azar de los cuatro alelos diferentes de los padres. El fenotipo (apariencia física) del individuo depende de cuál de los dos alelos es dominante y cuál es recesivo. Dado que los individuos pueden transmitir ambos alelos a su descendencia, la descendencia incluye tanto individuos con fenotipo dominante como recesivo.
What purpose does numerous microvilli serve?
A) Absorbs nutrients
B) Absorbs vitamin/s minerals
C) Absorbs foods/glucose
D) Increases surface area for absorption
E) All of the above
Answer:
D) Increases surface area for absorption
Explanation:
Microvilli are microscopic structures found mostly attached to the epithelial cells of certain organs. Microvilli helps the organs their found to increase the surface area for the diffusion of substances.
For example, microvilli in the epithelial cells of the small intestine helps to increase the surface area for the absorption of nutrients in the blood.

Why does the thermosphere increase in temperature as altitude increases?
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.
Explanation:
If an environment changes rapidly, organisms with _____ will be more likely to survive and reproduce.

Raghavan has two identical plants. He plants one outside in the ground. The other is growing indoors without direct light. Raghavan predicts the weight of the carbon dioxide and water taken in by the plant and the oxygen given off by the plant.
Raghavan notices that a rabbit family has been eating the outdoor plant and that small insects are eating the indoor plant. He sees a fox hunting rabbit, but nothing is eating the insects.
The diagrams show Raghavan’s plants. Raghavan predicted the weight of carbon dioxide and water taken in by the plant. He predicted the weight of oxygen given off by the plant. What should he predict for the weight of the sugar the plant made?

Which statement about the cell membrane is true?
A) It contains cellulose and sugars that are involved in communication.
B) It is present in animal cells only.
C) It is rigid and elastic for supporting the cell's shape.
D) It prevents harmful substances from entering a cell.
Answer:
Its D, The cell membrane(also known a the plasma membrane) has a job in which it has to allow passage in and out of the cell. Therefore it can prevent harmful substances from entering the cell. Think of it as security, either allowing you access or denying you depending on if you're a threat
Answer:
D) it prevents harmful substances from entering a cell
Explanation:
The entire purpose of the cells membrane is to contain its organelles, the structures within it and prevent them from getting harmed by outside material.
¿Cómo transformamos las fuentes de energía renovable en energía eléctrica necesarias para el desarrollo sostenible de nuestro país?
Answer:
Answer to the following question is as follows.
Explanation:
Natural energy is used to generate power in renewable technologies. Wind, wave, ocean, hydro, biomass, and solar energy are all potential sources of energy. ... A variety of technologies, such as floating offshore wind farms, biomass power plants, and hydroelectric systems, will be required to achieve this.
Renewable energy production and utilisation will enhance energy security, the environment, the economics, mechanical production, construction, transport, and industry, as well as assist in the creation of new employment. Solar, wind, and biomass energy can fulfil local energy demands while also helping to enhance environmental protection.

Organic compounds contain carbon atoms bonded to other atoms. The correct option is A.
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.
Thus, the correct option is A.

help me ..it's a MCQ
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!

A food chain consists of several organisms. Suppose one of the organisms in the chain disappears. What effect can this have on the other organisms in the food chain?
Answer:
All organisms in that food chain would starve until they die unless they could possibly move to a different habitat.
Explanation:
And because of all those organisms not being able to properly feed due to an organism missing in the food chain of that habitat, the population of those animals would decrease as well.
