Answer:

Viruses are not alive

Explanation:

Viruses are acellular structures capable of performing some biological functions.

What are viruses?

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.

What does a high population density indicate?

O The area is being overfished.

O The species is likely to face extinction.

O There is no other place for that species to live.

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

Answers

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."

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

The main components of the plasma membrane contain hydrophobic and hydrophilic regions that give the membrane selective permeability. Which of the following is the
main component that creates the hydrophobic and hydrophilic regions? (3 points)
a. Cholesterol molecules creating membrane fluidity
b. Carbohydrates for cell recognition
c. Glycolipids containing hydrophobic lipid portion
d. Phospholipids containing hydrophobic fatty acids tails

Answers

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.

Answers

EXPLANATION:

Modern monoculture requires vast amounts of rain for irrigating crops as moisture retention is limited in the soil. A lack of topsoil also increases rain runoff. To achieve this vast amount of extra water it means draining from lakes, rivers, and reservoirs, which is exhausting natural resources and aquatic ecosystems.

Answers

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.
