Much of our world is made up of plants, soil, and water. What do you think is
important about these three things? How do they interrelate?

Answers

They are all things found in nature and they help us live

Plants, soil, and water are interrelated to one another and help humans to sustain themselves on the earth's surface.

What do you mean by Soil?

Soil may be defined as the loose surface material that covers most land. It consists of inorganic particles and organic matter.

Water makes the soil moisturized which increases its fertility. When soil becomes fertile, the number of plants grows which directly absorbs water through the xylem and mediates the process of photosynthesis. In this way, all plants, soil, and water are connected to one another.

Therefore, Plants, soil, and water are interrelated to one another and help humans to sustain themselves on the earth's surface.

Answers

Explanation:

sana po nakatulong sainyo thanks❤

Cells are the basis of the survival of human beings. We, the living organisms are made up of cells. If cells won’t divide no new organisms would originate.

What is cell division?

Cell division is the process by which a parent cell divides, when a mother cell divides into two or more daughter cells. Cell division usually occurs as part of a larger cell cycle. Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.

The existing cells will die and no new cells will be produced as there is no cell division.

A strain of Neisseria gonorrhea has a mutation which has caused it to lose the ability to produce fimbriae and become less virulent as a consequence. What function has this pathogen lost

Answers

Answer: The pathogen has lost the function of the ability to adhere to cells of the body.

Explanation:

Neisseria gonorrhea is a gram negative bacteria that has the ability to attack and cause disease in man using its virulent factors. It is know to attack the urethra of both male and female producing an acute urethritis and tenda to spread locally if not treated. The virulent factors determines the ability of the organism to infect or damage it's hosts tissues and they include:

--> endotoxins

--> pilli

--> fimbriae

--> capsule polysaccharide expression

The fimbriae is one of the virulent determinants which the organism uses to attach to the host cells. As these bacteria multiple and grow, there are chances of mutation occuring. MUTATION is defined as the errors during DNA replication or induced by exposure to mutagens (like chemicals and radiation)

If the bacteria is affected by mutation, which can cause the gene for fimbriae production not to be expressed, the virulent factor of the organism will be highly affected as the first step to cause an Infection which is attachment is lost.

And also tell what is 1dm3​

Answers

Explanation:

1 dm3 is a cube with dimension 1 deci meter

One cubic decimeter is the unit of volume which is exactly equal to one litre.

What is meant by volume ?

Volume of an object is defined as the amount of space within the object which the matter can be occupied.

Here,

It is said that volume is a derived quantity.

Volume is said to be a derived quantity because, volume is the product of length, breadth and height of a three-dimensional shape.

It is given that,

1 L = 1000 mL

1 L = 1 dm³

1L = (10cm)³ = 1000 cm³

We know that, 1 cm = 10⁻²m

So, we can write that,

1L = 1000 x (10⁻²m)³

1L = 10³ x 10⁻⁶m³

Therefore,

1L = 10⁻³ m³

Or

1 m³ = 1000 L

1 dm³ or 1 cubic decimeter is the unit of volume, which is equal to one litre.

Hence,

One cubic decimeter is the unit of volume which is exactly equal to one litre.
