Answer:
I. Overall magnification (TM) = x40
II. Overall magnification (TM) = x100
III. Overall magnification (TM) = x400
IV. Overall magnification (TM) = x1000
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
Mathematically, the overall (total) magnification of a microscope is given by the formula;
Overall magnification (TM) = Eyepiece magnification(EM) X Objective magnification (OM).
I. When EM = x10 and OM = x4
TM = EM * OM
TM = x10 * x4
<em>TM = x40</em>
II. When EM = x10 and OM = x10
TM = EM * OM
TM = x10 * x10
<em>TM = x100</em>
III. When EM = x10 and OM = x40
TM = EM * OM
TM = x10 * x40
<em>TM = x400</em>
IV. When EM = x10 and OM = x100
TM = EM * OM
TM = x10 * x100
<em>TM = x1000</em>
The addition of dynactin caused dynein to travel farther along the micro tubule.
<u>Explanation:</u>
Dynein is a family of cytoskeletal motor proteins that move along micro tubules in cells. They convert the chemical energy stored in ATP to mechanical work. Dynein transports various cellular cargo, provides forces and displacements important in mitosis, and drives the beat of eukaryotic cilia and flagella.
Dynactin is a 23 sub unit protein complex that acts as a co-factor for the micro tubule motor cytoplasmic dynein-1. It is built around a short filament of actin related protein-1.
Answer:
homeostasis keeps you alive ex: shivering produces heat in cold temperatures
Autotroph produce their own food ex: plant
Heterotroph consume other organisms: humans
Explanation:
D) Ecological systems often remain in balance if only one factor is altered.
Ecological system can affect one another regardless of how small or great the factor that was altered. This can have gradual and insidious effects on the ecosystem. <span>Ecosystem is
encompassing all the life on earth in the physical environment that
supports it. An ecosystem involves both the biological (plants, animals,
human beings) and non-biological (land, water, soil, and atmosphere)
community which interacts as a system. More importantly, the living
things are very dependent on the abiotic community since it cannot
survive by itself.</span>
