Write a summary about the cell theory
julia-pushkina [17]

Answer:

Over the next two centuries after the discoveries of Hooke and Leeuwenhoek, biologists found cells everywhere. Biologists in the early part of the 19th century suggested that all living things were made of cells, but the role of cells as the primary building block of life was not discovered until 1839 when two German scientists, Theodor Schwann, a zoologist, and Matthias Jakob Schleiden, a botanist, suggested that cells were the basic unit of structure and function of all living things. Later, in 1858, the German doctor Rudolf Virchow observed that cells divide to produce more cells. He proposed that all cells arise only from other cells. The collective observations of all three scientists form the Cell Theory, which states that:

all organisms are made up of one or more cells,

all the life functions of an organism occur within cells,

all cells come from preexisting cells.

Though no one point of the Cell Theory is more important than another, the theory clearly states that the functions necessary for life occur in the cell. Findings since the time of the original Cell Theory have enabled scientists to "modernize" the theory, including points related to biochemistry and molecular biology. The modern version of the Cell Theory includes:

all known living things are made up of one or more cells,

all living cells arise from pre-existing cells by division,

the cell is the fundamental unit of structure and function in all living organisms,

the activity of an organism depends on the total activity of independent cells,

energy flow (metabolism and biochemistry) occurs within cells,

cells contain hereditary information (DNA) which is passed from cell to cell during cell division,

all cells are basically the same in chemical composition in organisms of similar species.

The Cell Theory is one of the main principles of biology. The points of the theory have been found to be true for all life. As with any scientific theory, the Cell Theory is based on observations that over many years upheld the basic conclusions of Schwann’s 1839 paper. However, one of Schwann’s original conclusions stated that cells formed in a similar way to crystals. This observation, which refers to spontaneous generation of life, was discounted when Virchow proposed that all cells arise only from other cells. The Cell Theory has withstood intense examination of cells by modern powerful microscopes and other instruments. Scientists continue to use new techniques and equipment to look into cells to discover additional explanations for how they work.

1. Why is the moon’s gravity weaker than Earth’s gravity?
vfiekz [6]

1 The Earth's Moon has considerably less mass than the Earth itself. Not only is the Moon smaller than the Earth but it is only about 60 percent as dense as Earth. Thus the gravitational attraction on the Moon is much less than it is here on Earth and a person weighs less on the Moon

2 The strength of the gravitational force between two objects depends on two factors mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled the force of gravity between the objects is doubled increases, the force of gravity decreases.

3 If the mass of one of the objects is doubled, then the force of gravity between them is doubled.  If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power).

The muscular system helps with ____ and the skeletal system helps with ____. Question 1 options: movement; oxygen exchange movem
Anna007 [38]

Answer:

The correct answer is movement; structure.

The muscular system helps with <u>movement</u> and the skeletal system helps with <u>structure</u>.

Explanation:

The human muscular system constitutes 40% of the total weight of our body and is made up of three types of muscles, which, together with different tendons and thanks to their contraction capacities, allow us to move. The muscular system and the function of the muscles allow the movement of our body and it is the one that works in tune with other systems of our body to guarantee normal general functioning..The skeletal system is the set of organs that support, shape, structure and protect the body. The skeleton is a dynamic structure, specifically the axial skeleton, it is to serve as a support or as a scaffold that supports the organs and structures of the body. This is how bones together with muscles work as a team to allow the mobility of the human body.
