Rust is another name for iron oxide, which occurs when iron or an alloy that contains iron, like steel, is exposed to oxygen and moisture for a long period of time. Over time, the oxygen combines with the metal at an atomic level, forming a new compound called an oxide and weakening the bonds of the metal itself.
Answer:
Option C. Cellular transport that does not require cellular energy, is the correct statement.
Explanation:
Movement of molecules requires energy for transportation from one place to another.
Passive transport is a type of transport in which molecules moves from one place to another without the use of energy. In passive transport, one molecule pulls another molecule and as a result the molecule moves from one region to another.
<span>An electroencephalogram (EEG) machine
EEG machine works by tracking and recording electrical activity of the brain in form of wave pattern. The instrument has electrode discs which are placed on ones scalp and then the electrical activity of the brain is detected and signals send to the computer which shows the result in form of a wave pattern. The doctors can there be able to detect any abnormal wave pattern and be able to diagnose if one is having seizure, stroke, tumor, epilepsy, brain death, coma or any other brain related abnormality.</span>
The nucleus! hope this helps :)
Answer: Meiosis; fertilization
In the human life cycle, diploid cells undergo a cell division process called meiosis. The resulting haploid cells later fuse during fertilization which regenerates diploid cells.
Explanation:
Diploid cells possess two basic sets of chromosomes known as homologous chromosomes. They undergo a two-step meiosis (Meiosis I and II) to yield four haploid cells with half the original chromosome number of the parent cell. These haploid cells are called sex cells or gametes.
The male and female gametes (sperm and egg) then fuses during fertilization to form zygote, a single cell with two sets of chromosomes (diploid number). Then, it undergoes mitosis to regenerates diploid cells with the same chromosome number as found in the zygote.
