Answer:
Some cells can support life independently, while other cells support life collectively
Explanation:
The cell theory, now universally accepted, contains three main statements: 1-all life forms are composed of cells, 2-cells always come from pre-existing cells, and 3-cells are considered as the basic units of all organisms. Cells are highly specialized structures that can perform specific functions. One single cell may contain all required materials to sustain life in a single-celled organism (e.g., prokaryotic bacteria and protists), where each cell is able to perform all metabolic functions, i.e., growth, development, reproduction, etc. Moreover, cells can also be organized into tissues, organs and systems of organs in multicellular organisms (e.g., plants and animals), in order to perform specific tasks such as, for example, gas exchange in specialized organs called lungs of terrestrial animals.
Answer: Between 1,000 and 11,000.
Explanation: The normal white blood cell count in a healthy adult is between 4,000 and 11,000 WBCs per microliter or cubic millimeter (mm3) of blood, but this may be different between males and females, as well as healthy children and other young people due to the possibility that they usually have more.
Hope I helped!!
Answer: Many left-handed people report being able to use their right hand very well for a certain burden(task), because of needing to adapt to tools which are usually designed for right-handed people like scissors, golf clubs, and some people are also mix-handed, where they perform some tasks with one hand and other tasks with the opposite hand. Some people have true ambidexterity where they can perform burden(task) equally well with both hands. Learning Point is were children begin to develop hand dominance around about 2 to 3 years and this should be well developed by the age of 5 and fully developed by the age of 6. Use of a dominant hand before 2-3 years time may occur because of abnormal fine motor development. It could also be the result of an intracranial injury or an injury to a limb with appropriate compensation by the other limb. The development of hand dominance after the age of 6 years, again may indicate abnormal development.
