Answer:

The answer is "2:1".

Explanation:

The formula of the Starch is = [tex](C_6H_{10}O_5)n[/tex]

The ratio of Hydrogen (H) and oxygen (O) is= 2:1.

The ratio of Hydrogen (H) and oxygen (O) in all carbohydrates (starch and sugar included) are 2:1.

Answer:

I would say ATP is needed for active transport to occur

Answer:

The answer is B. To make glucose molecules

Answer:

Phospholipids are able to form cell membranes because the phosphate group head is hydrophilic (water-loving) while the fatty acid tails are hydrophobic (water-hating).

Answer:

A. Vitamins seem to cause an increase in ink production

Explanation:

Because the experimental group, the one given vitamins, produces more ink than the control group, no vitamins.

Answer:

They are....

Explanation:

Biotic and Abiotic --->

*Biotic is all living things such as plants, and animals

*Abiotic is all Non- living things such as water, glass, oil, etc

Hope this helps!

The two types of natural resources are biotic and abiotic. Biotic resources are ones derived of organic origins, or may be grown, that are gathered from the biosphere. Abiotic resources are nonliving resources, like metals, water, or oil.

I hope this answers your question! Happy learning, friend :)

Answer:

activation energy is the answer

Answer:

You would look for water air living life forms and suitable places to live on the planet you would also look for oxygen so living life forms can breath, and lastly see if you can grow food or if food can stay on that planet.

This is how a life forms stays alive

So while the U.S. tends to go all out celebrating freedom on the Fourth of July, independence on July 4 are a reminder of the country's hypocrisy on the matter and bloody than are the people of the United States, at this very hour.

Explanation:

Answer:

The main components that creates the hydrophobic and hydrophilic regions of the plasma membrane are phospholipids containing hydrophobic fatty acids tails.

Explanation:

Phospholipids are the main component of the cell membrane —lipid bilayer— and responsible for its selective permeability.  Each phospholipid is composed of one glycerol molecule, which forms the head, and two fatty acid tails, plus one phosphate molecule.

In the lipid bilayer, the phospholipid heads are oriented towards the surface, while the tails are located inside, allowing interaction with both polar and apolar molecules.

The hydrophilic regions of the membranes are in contact with the liquids of the extracellular and intracellular spaces, while the hydrophobic region is inside the membrane, limiting the passage of polar molecules or ions.

The other options are not correct because:

    a. Cholesterol molecules are part of the membrane, but are not responsible for the hydrophobic and hydrophilic regions.

    b. Carbohydrates for cell recognition do not determine membrane permeability.

    c. Glycolipids, like integral proteins, are part of the membrane, but do not determine the polarity of the regions.

Answer:

Viruses are not alive

Explanation:

Viruses are acellular structures capable of performing some biological functions.

Viruses are parasitic structures made of an outer protein capsid and genetic material which are able to replicate in a living cell and thus cause infection in the cell.

Viruses hijack the replicative machinery of the host to produce copies of its own genetic material. A single infected cell is capable of producing thousands of viruses.

The virus only injects the nucleic acid inside the target cell, the envelope and capsid are left outside. The hijacked genetic machinery of the host produces further copies of the nucleic acid, capsid and envelope.

These structures are assembled to give rise to new viruses.

If a large number of viruses are synthesized rapidly, it results in cell lysis. This type of infection is called the lytic cycle.

If the virus genome incorporates with the host genome, it is present there silently and being replicated. Upon receiving an activation signal lytic cycle is activated. It is called the lysogenic cycle

Therefore, viruses are acellular structures capable of performing some biological functions.

Explanation:

Answer:Temperate grassland, desert, temperate woodland, and shrubland, northwestern coniferous forest and temperate forest.

Explanation:

Answer:

Differences in the concentrations of ions on opposite sides of a cellular membrane lead to a voltage called the membrane potential. Typical values of membrane potential are in the range –40 mV to –70 mV. ... These concentration gradients provide the potential energy to drive the formation of the membrane potential.

Desalination

Explanation:

desalination is a technique where the excess salt are removed from salt water or brackish water.

Answer:

Most environmental issues are problems on a global scale, these include but are not limited to, global warming, ozone pollution, greenhouse gases and many more issues.

This affects the way we try to solve these issues because if we dont all play a part to help change the way things are going, then they will only get worse. We have to come together as a whole.

Unlike individual efforts, different countries can cooperate and implement legislation which limitates all the countries in the globe,solving environmental issue more efficiently.

If I were you, I would make my hypothesis something like:

"If the vegetation type is a savannah/woodland, then it will support the highest abundance of life."

Explanation:

I know that hypothesis can be tricky to write at first, but if you turn the research question into a sentence, then you can write your hypothesis. Best of luck with your experiment.

Explanation:

Answer:

O Food supply is high and the number of predators low.

Explanation:

Population density is defined as the population living in per square mile/km.

High population density indicate that the people living in an area have high food supply and the number of predators low. Predators are responsible to control the population but due to high food supply and low predators, there will be no control in the population and no control in the feeding behavior of the population that leads to High population density.

Hence, the correct option is "Food supply is high and the number of predators low."

Answer:

D; Food supply is high and the number of predators low.

Explanation:

As well as carbohydrates, lipids also contain carbon, hydrogen and oxygen (since they have a hydrocarbon chain and glycerol backbone)

Proteins can also contain nitrogen atoms (amino acids); proteins also have an 'R' group; proteins also are folded structures

The nitrogen, phosphate groups, carbon rings are component phospho(lipids)

Lipids also have fatty acid chains and glycerol

Answer:

A Carbon Dioxide ( CO2)

Explanation:

During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. ... Then, via respiration processes, cells use oxygen and glucose to synthesize energy-rich carrier molecules, such as ATP, and carbon dioxide is produced as a waste product.
