Select all of the arrows in the model that represent the movement of nitrogen from an abiotic system to a biotic system.

Answers

Answer:

Nitrogen compounds in the soil ---> Plants

Nitrogen compounds in the soil ---> Denitrification bacteria (convert nitrogen compounds to N2)

Nitrogen in the atmosphere ---> Nitrogen fixing bacteria (convert N2 to nitrogen compounds)

Explanation:

This model in the image section is portraying the nitrogen cycle, which involves the transfer of nitrogen within biosphere, atmosphere, and lithosphere etc. The abiotic components of this model are the non-living parts while the biotic components are the living parts.

In this model, the movement of nitrogen from abiotic or non-living component of an ecosystem to the biotic or living component is as follows:

Nitrogen compounds in the soil ---> Plants

Nitrogen compounds in the soil ---> Denitrification bacteria (convert nitrogen compounds to N2)

Nitrogen in the atmosphere ---> Nitrogen fixing bacteria (convert N2 to nitrogen compounds)

These always contain DNA as the main genetic material

A. Virus
B. Both
C. Cells

Answers

Answer:

C

Explanation:

The one that always contain DNA as the main genetic material is cell nucleus. The correct option is C.

What is genetic material?

The genetic material is the molecule that contains genes and is passed down from parents to children. It contains instructions for the growth and function of living organisms.

DNA and RNA are the two main types of genetic material. DNA is stored in the nucleus of eukaryotic cells, which have a nucleus and membrane-bound organelles, and is wrapped around round proteins called histones. DNA is ended up finding in the cytoplasm of prokaryotic cells.

A virus is composed of a core of genetic material surrounded by a protein-based protective coat called a capsid.

Viruses have either RNA or DNA as their genetic material, but neither. Single-stranded or double-stranded nucleic acid

Thus, the correct option is C.

Metalloids that can conduct electricity at higher temperatures are called semiconductors. Silicon is an example of a semiconductor.

Hope that helps

Metalloids that can conduct electricity at high temperatures are called semiconductors.



Semiconductors are a group of elements that have properties intermediate between those of metals and nonmetals. They have some characteristics of metals, such as being able to conduct electricity, but also some characteristics of nonmetals, such as having lower conductivity than metals.

At low temperatures, semiconductors have very low conductivity. However, at high temperatures, they can conduct electricity more effectively. This is because at higher temperatures, the thermal energy causes more electrons to break free from their atoms and become available for conduction.

One example of a semiconductor that can conduct electricity at high temperatures is silicon. Silicon is widely used in electronic devices, such as computer chips and solar cells, due to its ability to control and amplify electrical signals.

In summary, metalloids that can conduct electricity at high temperatures are known as semiconductors. They have properties intermediate between metals and nonmetals and can conduct electricity more effectively at high temperatures. Silicon is an example of a semiconductor commonly used in electronic devices.

it would be cryosphers and hydrosphere

The climate change increases the overall temperature of the earth, glaciers can melt into the ocean. The spheres involved cryosphere and hydrosphere. Thus option A is correct.

What is cryosphere?

Cryosphere is defined as solid precipitation, snow,  sea ice, lake and river ice, icebergs, glaciers and ice caps, ice sheets, ice shelves, , and seasonally frozen ground are all components of the Earth's climatic system.

It can also be defined as the area of the earth's surface marked by the presence of water.

Hydrosphere is defined as the total mass of water on, beneath, and above the surface of a planet, minor planet, or natural satellite.

It can also be defined as the component of the Earth made up of all liquid water.

There are basically three types of hydrosphere.

Climate change is defined as the long-term temperature and weather pattern shifts These changes could be natural, such as oscillations in the solar cycle.

Answers

Answer:

The reason why Dr Naskrecki thinks he suspects there are so many more than the 2,829 species they have already identified living in the park is because there are many species that has been identified in the world because humans haven’t gotten to most parts of the earth which makes it a lot undiscoverable.

What macromolecules can be found in plant cells

Answers

Answer:

ANIMALS: There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell's mass.

PLANTS: The three main classes of macromolecules found in plants are thus proteins, polysaccharides and nucleic acids. However, mixed polymers are also known. such as the glycoproteins, which contain both sugars and amino acids in covalent linkage.

The macromolecules found in animal cells are carbohydrates, proteins, lipids, nucleic acids, and water. Each of these macromolecules has specific functions in the body of kingdom Animalia.

What are Macromolecules?

Macromolecules may be defined as a molecule that contains a very large number of atoms that are held together by specific bonds.

The macromolecules found in animal cells are polysaccharides, proteins, nucleic acids, water, and some types of mixed polymers.

All such macromolecules perform specific functions in the structure of kingdom Plantae and meet the need for metabolic activities.

The lytic and the lysogenic cycles are the two methods that bacteriophages reproduce.  They both begin with a bacterium that has been infected with bacteriophage DNA.

Lytic:

The phage DNA reinstructs ribosomes and the bacterium begins producing many bacteriophages.The bacterium eventually lyses and releases the bacteriophages into the environment

Lysogenic:

The phage DNA is incorporated into the bacterium's chromosome.The bacterium eventually duplicates this DNA when it undergoes fission, producing two infected daughter cells.Eventually, the phage DNA will be read by the bacterium and it will go into the lytic cycle, described above.

To sum it up, the lytic cycle ends the bacterium's life by producing offspring, yet the lysogenic cycle allows for multiple bacteria to divide and eventually undergo the lytic cycle.

Would you need 1 x 10° or 1 x 10' stadiums to hold


the same number of people as the number of atoms in


a grain of iron? Explain your answer,

Answers

Answer:

1 x 10^13 stadiums will be needed in this scenario

Explanation:

We are told that

1 stadium holds = 1 × 10^5 people and

Number of iron atoms = 1 × 10^18 atoms

If the stadium carries an equivalent number of atoms as that of people.

We can infer that 1 stadium will carry 1 × 10^5 atoms.

The calculation to determine the number of stadiums would then be 1 × 10^18 divided by 10^5 atoms/stadium which was gotten by dividing the total number of atoms by the number of atoms per stadium.

Number of stadiums = Total number of atoms ÷ Number of atoms per stadium

= 1 × 10^18 atoms ÷ 1 × 10^5 atoms/stadium

= 1 × 10^13 Stadiums

This means that 1 × 10^18 atoms would occupy 1 × 10^13 stadiums
