Answer:

The rusting of iron may be defined as the process of formation of the oxide layer by the attack of oxygen and moisture on the surface of iron. This rusting changes the color and reduces the value of iron.

The iron turns into the brownish red powder due to the oxidation of iron. The oxygen in the presence of moisture reacts with iron to form a brown layer known as rust. The reactants are oxygen, water and iron. The products are iron oxide (brown rust).

The brownish-red powder on iron is called rust. It is formed by the reaction of iron and oxygen in the presence of water or air moisture. It is called oxidizing or rusting due to exposure to water and air.

The reactants are oxygen and iron the products are carbon dioxide and water and the process is oxidization.

Answer:

Please find the similarities and differences between these cells below.

Explanation:

According to this question, six specific cells are examined. They are: neuron, red blood cell, osteocyte, skeletal muscle cell, sperm cell, and egg cell.

SIMILARITIES:

These cells are cells that make up different tissues and systems in living organisms. They perform different functions in their respective locations, however, they are similar in the sense that they all possess some cellular components called organelles. The organelles that are common to all these types of cells are CELL MEMBRANE, RIBOSOMES, MITOCHONDRIA, GENETIC MATERIAL (DNA), NUCLEUS,

They also possess two set of chromosomes in their nucleus i.e. diploid.

DIFFERENCES:

However, they differ in their functions. For example;

- neuron: nerve cell whose function is related to the nervous system

- red blood cell: blood cell whose function is related to circulatory system

- osteocyte: bone cell whose function is related to the skeletal system

- skeletal muscle cell- muscle cell whose function is related to the muscular system

- sperm cell: a male sex cell whose function is related to reproduction

- egg cell: a female sex cell whose function is related to reproduction

Species X and species Y belong to the same domain. Species Y and species Z belong to the same kingdom. Based ONLY on this inform

Stells [14]

Species X and species Z belong to the domain.

Answer: Option A.

<u>Explanation:</u>

Species which belong to the same domain, they also belong to the same kingdom and also to the same phylum. These species are very similar to each other and can also produce offspring together.

In the information given, species X and species Y belong to the same domain. The next column says that the species Y and species Z also belong to the same domain. So species X and species Z will also belong to the same domain.

The Earth is about 4.6 billion years old. However, the oldest sea floor is only about 180 million years old. What do you think i

natita [175]

Answer:

The seafloor is only 180 million years old due to the process of subduction. The floor of the sea's tends to get colder and denser with the passage of time. At a certain time, the seafloor becomes so dense that it sinks in the upper mantle. The Earth's crust cannot undergo this process and hence has oldest rocks. We can say that the seafloor is less than 180 million years old because it is typically recycled back into the mantle of the Earth.

If 84 J of work are exerted to pull a wagon, how much force does it take to pull the wagon 7.0 m? Round your answer to the neare

nirvana33 [79]

Work is said to be done when an object moves due to a force applied. Work is calculated by multiplying the force applied and the distance traveled due to the force. It is expressed as:

W = Force x distance

W = 84 J = F (7.0 m)
F = 12 N

Hope this answers the question.
