Answer:

All living organisms are composed of cells

Explanation:

Before the invention of advanced and complex microscopes used today, scientists like Anton Van Leeuwenhook observed some living organisms e.g Protista using his invented lens (now ancient) but later in 1665, Robert Hooke, was able to coin the term "cell" for the box-like structures he observed when viewing corked tissues through a lens.

However, in the 1800s, this view began to change thanks to the advancement in lens and the construction of microscope, which enabled scientists to see components of the cell. Microscopes allowed early scientists to view and postulate about the cells they could see. In 1839 specifically, Scientists like Mathias Schleiden and Theodor Schwann formulated a general theory of how cells work that is very simple, which was later spiced up by Rudolf Virchow.

The universally accepted historic scientific theory called Unified Cell theory states that:

1. All cells are made up of one (unicellular) or more (multicellular) cells.

2. The cell is the basic and fundamental unit of life and;

3. New cells arise from previously existing cells

Answer:

hydrogen bond

Explanation:

by weak electrical attraction between two polar molecule hydrogen bond is developed between them

the example is water molecule in case of water two water molecules are attracted toward each other by strong hydrogen bond which is developed between highly electronegative oxygen of one water and electropositive hydrogen of another water molecule

if a mutation occurs in the somatic tissue, approximately how many of the gametes will carry the mutation?
Mrac [35]

None: Only those mutations that occur in the germ line and result in gametes will have a chance of being passed on to progeny. An alteration in DNA that occurs after conception.

Somatic mutations can occur in any of the body's cells except germ cells (sperm and egg) and are therefore not passed on to children. These alterations can (but not always) cause cancer or other diseases. Mutations in somatic cells are called somatic mutations. Because they do not occur in the cells that give rise to gametes, the mutation is not transmitted to the next generation sexually. Human somatic cells have 46 chromosomes: 22 pairs and 2 sex chromosomes that may or may not form a pair. This is the 2n or diploid condition. Human gametes have 23 chromosomes, each of 23 unique chromosomes, one of which is a sex chromosome. Somatic cells are the cells in the body other than sperm and eggs (called germ cells). In humans, somatic cells are diploid, meaning they contain two sets of chromosomes, one inherited from each parent. Mutations in a somatic cell occur in somatic cells and are transmitted by mitosis, resulting in cancer. However, mutations in a gamete are passed on by meiosis, resulting in mutated offspring. A genetic mutation occurs during DNA replication, and chromosomal mutations occur during meiosis.
