How many elements are there in a molecule of
Ethanol shown in the above formula?

Answers

Answer 1

Answer:

9 elements

Explanation:

there are 2 C

6 H

1 O

Answer 2
There’s are 3 elements: Carbon, Hydrogen and Oxygen

Ethanol consists of 9 atoms:

2 Carbons
6 Hydrogens
1 Oxygen

2 + 6 + 1 = 9 atoms in total

Although the question doesn’t ask for atoms I just wanted to make things clear between them so you don’t get the numbers mixed up. Apart from that, there are 3 elements present in Ethanol.

All the DNA from a desired organism is isolated to form recombinant DNA for use in a host. C. Different sections of DNA from a desired organism are inserted into a host so that beneficial traits will be expressed. D. One strand of DNA is isolated and inserted into a host so recombinant DNA can be formed.

Answers

Answer:

A. Fragments of DNA that have desired genes are isolated to form recombinant DNA for use in a host.

Explanation:

Genetic engineering, also known as genetic modification, is a technique that involves the manipulation of an organism's genome using biotechnology procedures. The purpose of genetic engineering is to create an organism with desirable traits.

Genetic engineering involves series of steps, however, the very first step is that of DNA EXTRACTION. The fragments of DNA that have desired genes are isolated from the involved organism. The extracted DNA called the recombinant DNA, which is inserted into the host genome.

The sputum (fluid coughed up from the lungs) of many smokers contain cells with mutations in the genes for p53. The smoking-induced mutations appear to be an early signal showing that cancer of the lungs will follow. What is the likely relationship between early p53 mutation and the development of lung cancer

Answers

Answer:

The correct answer would be - mutations in the p53 would prevent abnormal cells from dying by apoptosis.

Explanation:

P53 or tumor protein 53 gene is the gene that produces a protein that controls DNA repair and apoptosis in the cell cycle if there is an error in the DNA or cells growing abnormally therefore known as tumor suppressor gene.

If there is a mutation in this gene will prevent it from performing its function of DNA repair or stimulating apoptosis and then p53 would prevent abnormal cells from dying by apoptosis.

Thus, the mutation in P53 would lead to the growth or development of lung cancer.

Kate and Sam are using a scanning electron microscope to study photosynthesis in algae. Which is a benefit of this type of microscope compared to
a light microscope?

Answers

Answer:

B. Produces highly magnified images

Explanation:

Trust me

Kate and Sam are using a scanning electron microscope to study photosynthesis in algae, and the benefit of using this type of microscope rather than a light microscope is that the scanning microscope gives clearer details of the process.

What are the benefits of using a microscope?

The microscope gives a better view of the smaller things, and there are different types of microscopes, such as the light microscope, the electron microscope, etc., and other high-quality microscopes that are helpful for the better viewing of the samples. The light microscope has a lower magnification range than the electron microscope, and the species can be better viewed in the electron microscope. Depending on the application, different microscopes should be used, and photosynthesis can be seen better in a scanning microscope than in a light microscope.

Hence, the benefit of using this type of microscope rather than a light microscope is that the scanning microscope gives clearer details of the process.

Explanation:

In meiosis,  Each chromosome will divide to produce two diploid daughter cells, each of which has the same number of chromosomes.

What do you mean by meiosis?

Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells.

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.

Therefore the purpose of meiosis is to produce gametes, the sperm and eggs, with half of the genetic complement of the parent cells.

Ecosystems Unit Test 8 of 8 Items Item 8 Discuss an ecosystem in which there is a producer, a consumer, a secondary consumer, and a decomposer. Name the ecosystem and specific organisms for a producer, consumer, secondary consumer, and decomposer

Answers

Answer:

The ecosystem, in this case, is a forest. The producers are plants. The deer, who eats the plants, is the consumer. The wolf, who eats the deer, is the secondary consumer, and earthworms are the decomposers.

Explanation:

An ecosystem is a group of beings that are in a certain area where they interact with each other and with their surroundings. In this case, we describe a trophic level with beings that are in the forest.

Producers are beings that produce their food, like plants.Consumers or primary consumers are animals that eat producers. They are herbivores.Secondary consumers eat primary consumers. They can be omnivores, or like in this case, carnivores.Decomposers are bacterias, mushrooms, or earthworms. They act on all levels breaking down the rest of the animals and plants, obtaining nutrients to nourish the soil, and start the cycle again.

What is one way that Earth's ocean currents help regulate global climate?
A.
by creating an uneven distribution of the Sun's energy across Earth's surface
B.
by moving warm water and precipitation from the Equator toward the poles
C.
by carrying cold water and floating ice from the Equator toward the poles
D.
by transmitting sunlight from the ocean surface to the ocean floor

Answers

The correct answer is “B” ;)

By moving warm water and precipitation from the equator to the poles and cold water from the poles back to the tropics, ocean currents function much like a conveyor belt, hence option B is correct.

What are Earth's ocean currents?

Global climate is regulated by ocean currents, which also assist to balance out the unequal distribution of solar energy hitting Earth's surface.

Sunlight energy is absorbed and stored by the ocean, which controls the temperature of the Earth's atmosphere. More than half of the solar energy that reaches Earth's surface is absorbed by the ocean, which both absorbs and releases heat more slowly than land.

By moving warm water and precipitation from the equator to the poles and cold water Global climate is regulated by currents, which assist balance out the unequal distribution of solar energy that reaches the surface of the Earth.

Therefore, by moving warm water and precipitation from the equator to the poles and cold water from the poles back to the tropics, hence option B is correct.

Michael and Jose are studying about plate tectonics. They learned that plates usually move a few centimeters every year. They learned that the movement of heated material caused the plates to move. In which layer does the heated material move?

Answers

Answer:

Mantle layer

Explanation:

The movement of heated materials on the mantle layer of the earth helps in the movement of the tectonic plates. The earth is made up of four layers and they are the crust, the mantle, the outer core, and the inner core. The tectonic plates are always in motion which is very slow but constant.

The convection currents emanating from the mantle layer of the earth aids the movement of the tectonic plates. Natural disasters like earthquakes can result from the intense pressure emanating from the movement of the plates.

Which kind of organism is an autotroph? consumer producer decomposer herbivore

Answers

Answer:

Producer

Explanation:

An autotroph is a type of organism that is capable of producing its own food from inorganic substances. The correct answer is "producer."

Describe autotroph.

Autotrophs utilize various processes to convert energy into usable forms. The most common and well-known method is photosynthesis, which involves capturing sunlight and using it to convert carbon dioxide and water into glucose (a type of sugar) and oxygen. Plants, algae, and some bacteria are examples of autotrophs that perform photosynthesis.

They are often referred to as producers because they can convert energy from sunlight (or other forms of energy) into organic compounds through processes like photosynthesis or chemosynthesis.

Autotrophs, such as plants, algae, and some bacteria, are able to synthesize their own nutrients and energy sources, typically using sunlight, water, and carbon dioxide. They form the foundation of food chains and provide energy for other organisms in ecosystems.

Therefore, the correct answer is "producer."
