Matter can be broken down into two categories: pure substances<span> and </span>mixtures.Pure substances<span> are further broken down into elements and compounds. ... A chemical </span>substance<span> is composed of one type of atom or molecule. A </span>mixture<span> is composed of different types of atoms or molecules that are not chemically bonded</span>
Answer:
In the physical sciences, subatomic particles are smaller than atoms. They can be composite particles, such as the neutron and proton; or elementary particles, which according to the standard model are not made of other particles.
Explanation:
Answer:
A spade placed in the fire turns hot.
Explanation:
Answer:
Sulfur; nitrogen.
Explanation:
Acid precipitation results when sulfur and nitrogen compounds react with water in the atmosphere.
This acid precipitation is also known as acid rain and it is typically caused by the chemical reaction between sulfur oxide and nitrogen oxide which are released into the air as a result of burning fossil fuels, with water and other chemical elements present in the atmosphere.
Generally, acid precipitation (acid rain) usually have a pH of about 5.1 or below and as such, it is very acidic nature i.e possessing a large amount of hydrogen ions.
Hence, acid precipitation (acid rain) when washed to the earth has negative or harmful effects on various living and non-living organisms such as animals, plants, cars, buildings etc.
Fertilization and formation of the zygote occur Within the body of mosquito.
Zygote, from the Ancient Greek (zygtós), "attached, yoked," from (zygoun), "to join, to yoke," A fertilization between two gametes produces a eukaryotic cell. The genome of a zygote, which consists of the DNA from each gamete, is what makes up a new individual creature and holds all of its genetic material.
The zygote is the first developmental stage in animals with many cells. When an egg cell and sperm cell unite to produce a new, distinct organism, a zygote is created in humans and the majority of other anisogamous species. With the aid of mitosis, the zygote can divide asexually in single-celled organisms to create identical progeny. The chloroplast DNA (cpDNA) of a Chlamydomonas zygote is inherited uniparentally from the parent with the mt+ mating type; as a result, such cells are typically uncommon. The mapping of chloroplast genetics through recombination was made possible by these uncommon biparental zygotes.
