Total magnification of objects is 12x.
Dissecting microscopes are microscopes with only one set of lenses so they have less magnification than a compound microscope.
The eyepiece, or ocular lens of microscope, usually has a magnification of 10x. The numbers on magnification knob range from about 0.7 to 3. So, when you want to calculate the total magnification multiply the magnification on the eyepiece with the number on the magnification knob.
Ovulation is the process in which eggs are released from the ovary.
The environmental factors leading to injuries are often associated with other environmental health risks. For example, home and school construction and furnishing materials can lead to unintentional injuries, and poisoning may result from exposure to chemicals unsafely used or stored.
Answer:
water is essential for life as we know
Explanation:
Water (H2O) is essential for life (i.e. carbon-based life) because this molecule has unique chemical properties. First, water is a universal solvent that helps cells to transport and use essential molecules (e.g., oxygen and nutrients). Second, water molecules help cells to maintain their shape/structure by generating pressure within the cells. Third, the polarity of water helps the formation of phospholipidic membranes because phospholipids have polar heads that interact with water and nonpolar tails that interact with each other. Fourth, water has a high heat capacity, thereby helping to regulate the temperature in the (intracellular) environment. Finally, water molecules also have unique adhesion and cohesion properties that enable the movement of substances against gravity (adhesion) and create a surface tension (cohesion) that helps to the formation of bubbles with water.
