Answer:
The body parts are arranged like spokes on a wheel
Explanation:
Bilateral symmetry is when it is as two halves. And the other two options are not types of symmetries.
Answer:
The correct order from smallest to largest are: Molecule, Cell, Tissue, Organ, Organ system and Organism.
Explanation:
- <u>Molecule</u> : They are very small particles or substance specially at both structural and cellular level. These are made up of two or more atoms which are held tightly by strong chemical bonds. The four important molecules of life are proteins, carbohydrates, lipids and nucleic acids.Without any of these molecules,survival of organisms and cells is very difficult. These molecules are very important in both the ways structurally as well as functionally.
- <u>Cell </u>:Cell is the most important, structural and functional unit of life. A cell is blessed with a capacity to carry out the main functions like nutrition, excretion and respiration. Cell is the important membrane bound unit that includes fundamental molecules of life of which all living organisms are made up of. A single cell is sometimes a complete organism in itself like bacterium or yeast. The four main types of cells are Epithelial cells, nerve cells,muscle cells and connective tissue cells.
- <u>Tissue</u> : A tissue is an assembly of similar cells and their extracellular matrix belongs to the same origin which combines together and carry out a specific function. Organs are the formation of functional groups of multiple tissues.There are four main types of tissue: muscle, epithelial, connective and nervous. Each is made up of special cells which are combined together depending on their structure and function. Example of connective tissue include fat & loose connective tissue
- <u>Organ </u> : An organ is a self contained cluster or sets of tissues which perform a specialised functions in the body.Two or more organs are working together in order to perform a special body functions forming an organ system also known as body system.When organs began to shut down, person will feel drowsy and starts losing consciousness. When the heart and lungs stop working body also dies. Heart rate changes. Pulse becomes fast or irregular.
- <u>Organ System:</u> An organ system is a set/ cluster of organs which are working together to perform a certain function in the body of an organism.The 11 organ systems of the body are integumentary, muscular, nervous, circulatory, lymphatic, respiratory, endocrine, urinary, reproductive and digestive
- <u>Organism</u>: It is a creature like plant, animal or single cellular life form in comparison to a living creature. They reacts to stimuli, reproduce grow and also play a main role in homeostasis. It can be virus, bacteria, protist, fungi or animal.
Answer:
.D. two daughter cells with twice the amount of DNA.
Mitosis is a multiplication division with the daughter cells having twice(diploid) the amount of DNA present in the parent cells that is 2n, The Chromosomes number doubles in the daughter cells , and therefore the DNA also doubles with each successful generation in the daughter cells. It is this ability to multiply the genetic components that makes Mitosis to be called multiplication division.
The parents and daughter cells are exactly similar.
Each daughter cell with its double genetic composition can also pass on to its own subsequent generation the genetic composition since its DNA and chromosomes . Thus enough amount can be passed to its own daughter cells too, which explains the need for double DNA inherited from the parents
