The answer is B.
Sex cells are formed by a process called meiosis, not mitosis.
Answer:
The correct answer is option B. The contraction forces of the innervated muscle fibers.
Explanation:
Electromyography or EMG is the study of muscle activity with the help of analyzing electric signals that are burst or generated by the contraction of the muscle fibers. In other words, it is the electrical activity of the skeletal muscles in response to a nerve's stimulation of the muscle.
EMG uses the myoelectric signals to analyze muscle that is generated during the contraction forces of the inverted muscle fibers of the skeletal muscle.
Thus, the correct answer is option B. The contraction forces of the innervated muscle fibers.
Answer:
The conclusion is that different matters have different biomass percentages.
Explanation:
Different matters have different biomass percentages because they are formed from different elements. each biomass is formed from the elements such as carbon, oxygen, hydrogen and nitrogen. for example, the human body is composed of 30 percent of biomass while 70 percent is water. the percentages of different elements are carbon (12%), nitrogen (0.6%), hydrogen (62.9%), oxygen (24%), calcium (0.24%) and phosphorus (0.14%). At each level, only 10 percent of biomass is transferred to another level and remaining 90 percent releases in the form of heat.
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.
