Which organisms are eukaryotes?
animals
plants
archaea
fungi
Answers
Answer:
Bacteria and archaea are prokaryotes, while all other living organisms — protists, plants, animals and fungi — are eukaryotes.
Explanation:
Among the mentioned types of organisms, animals, plants and fungi are eukaryotes and archaea are prokaryotes.
What are eukaryotes?The organisms having a true membrane-bound nucleus with membrane-bound organelles in their cell are called eukaryotes. Eu - true, karyon - nucleus. So the word eukaryotes mean the organism having a true nucleus.
In the 5 kingdom system of classification, every kingdom except Monera consists of eukaryotes. Monera consists of unicellular prokaryotes and this includes two groups of organisms, they are archaea and bacteria.
Protista, fungi, Plantae and Animalia kingdoms consist of eukaryotes. Protists are unicellular eukaryotes and the rest are multicellular eukaryotes.
Kingdom fungi include saprophytic multicellular eukaryotes. The kingdom Plantae includes photosynthetic multicellular eukaryotes. The kingdom Animalia includes heterotrophic multicellular eukaryotes.
Therefore, the correct options are animals, plants and fungi.

Where does the energy that powers the nitrogen cycle come from?
Answers
Answer:
When nitrogen is absorbed by the soil, different bacteria help it to change states so it can be absorbed by plants. Animals then get their nitrogen from the plants. Fixation - Fixation is the first step in the process of making nitrogen usable by plants. They absorb nitrates from the soil into their roots.

What is the role of the carbon cycle? (100 points) Detailed answers please!
Answers
Answer:When new life is formed, carbon forms key molecules like protein and DNA. It's also found in our atmosphere in the form of carbon dioxide or CO2. The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again.
Explanation:
Answer:
the carbon cycle is the process in which co2 i
travels from the atmosphere to organisms and back to the atmosphere. The four steps of the carbon cycle are photosynthesis, decomposition, respiration, and combustion. Then carbon cycle starts by carbon moving from the atmosphere to plants. The carbon then moves from plants to animals. And then it moves from plants and animals to soil. The carbon then moves from living things back to the atmosphere. Carbon also moves to the atmosphere from the burning of fossil fuels. carbon also moves from the atmosphere to the oceans. Carbon is a life sustaining element . The carbon cycle is important because it move carbon throughout different ecosystems.

HELP PLS First, Demetri will test the three solutions containing milk (lactose).
He begins the experiment by preparing the lactase enzyme solutions. In one beaker he dissolves 1 lactase tablet in 100 mL of water at room temperature. He stirs the mixture until the tablet has dissolved completely. He repeats this process in a second beaker, and then heats the beaker until the solution is boiling.
Demetri then tests these three milk (lactose) solutions for the presence of glucose:
milk in water
milk and lactase enzyme in water
milk and heated lactase enzyme in water
Test Tube 1 - Milk (Lactose): Demetri fills the first test tube one-quarter full of milk. Then, he slowly adds water to the milk until the test tube is three-quarters full. Using the stirrer, Demetri thoroughly mixes the solution. Then he inserts the test strip for 30 seconds and records its color.
Test Tube 2 - Milk (Lactose) and Lactase Enzyme: Demetri fills the second test tube one-quarter full with milk. He then adds the lactase-and-water solution until the test tube is three-quarters full. He uses a stirrer to thoroughly mix the solution. Next, Demetri inserts the test strip for 30 seconds and records its color.
Test Tube 3 - Milk (Lactose) and Heated Lactase Enzyme: Demetri fills the third test tube one-quarter full with milk. He then adds the heated lactase-and-water solution until the test tube is three-quarters full. After stirring, Demetri inserts the test strip for 30 seconds and records its color.
According to the test strips, which of these milk solutions contained glucose?
Answers
Answer:
2nd test tube, because test strip color turned to green, which indicates this test tube solution contained glucose.
Explanation:
Lactase will break down the lactose into glucose and galactose. In first test tube there is no such activity because there is no lactase presented. In 3rd test tube as the enzyme is heated so it is get decomposed so in this case also there is no activity of lactase enzyme.
The second tube is the tube that contained glucose.
We can arrive at this answer because:
Lactase is a protein.This protein has the function of breaking lactose into smaller molecules, which are glucose and galactose molecules.This protein is sensitive to high temperatures and loses functionality in very hot environments.In the case of the tests used in the question above, we can say that in the first test tube, the lactase solution was not added, so the lactose was not broken down. The lactase solution was added to the second test tube, where the lactose was broken down generating glucose and galactose. In the third test tube, the heated water prevented the lactase from acting and therefore it cannot break down the lactose.
Therefore, only the second tube has glucose.

What is the percentage of Thymine if you have 18 % Guanine in a strand of DNA?
32

22
18
Answers
Answer: 32%
Explanation: Remember the base pairing rules: cytosine with guanine and adenine with thymine, in equal amounts. That being said, the amount of cytosine is equal to the amount of guanine, meaning that it is 18% as well. Since 18+18=36, you know that the remaining 64% is adenine and thymine collectively. To figure out how much of each base there is, you could divide 64% between each nitrogenous base to get 32% each.

If a DNA strand has 26% cytosine, what percent thymine will each new strand have after replication?
Answers
Answer: Each new strand would have 24% thymine
Remember the base pairing rules: cytosine with guanine and adenine with thymine, in equal amounts. Since you know that there is 26% cytosine, the amount of guanine is also 26%. 26+26=52, so that means that 52% is cytosine and guanine collectively, which means that the remaining 48% is adenine and thymine. Since these are also equal, you could divide 48% between the two bases to get 24% each.

A city is considering switching to geothermal power for their electricity needs. Which of the following is an advantage of this plan?
1. It is commonly used across the entire United States.
2.It uses less land area than gas power plants.
3.It uses water to power large turbines.
4.It in inexpensive to build.
Answers
It uses water to power large turbines.
Geothermal power taps on the energy of natural steam from the earth's lithosphere.
Explanation:
The heat from deep in the the lithosphere heats up underground water into high-pressure steam trapped in within the rocks. Boreholes are sunk to tap on the potential energy of this high-pressure steam to turn large dynamo turbines that convert the steam energy into electricity.
The biggest advantage, moreover, is the fact that this method of electricity generation does not emit greenhouse emissions as compared to gas plants that burn hydrocarbons that release CO₂.
