Answer:
Mass is the measurement of what amount of matter is contained in an object. Whereas
weight is the measurement the pull of gravity on an object.
Another way to differentiate both is Mass is measured on a balance comparing a known amount a matter of to an unknown amount of matter and weight is measured on a scale.
Unlike weight, mass never changes due to the location of something. The mass of an object is measuring how much matter is in it.
Weight usually is denoted by W. Weight is mass multiplied by the acceleration of gravity.
Scalar quantity: one dimensional measurement of a quantity, like temperature, or mass. Vector: more than one number associated with it. Ex: Displacement, speed, velocity.
Answer:
Cross a red flower (AaBB) with a pink flower (AaBb). What are the expected phenotypic ratios of offspring?
AaBB x AaBb= AABB, AaBb, AaBB, aaBb
Phenotyic ratio is 3:1
Explanation:
A.Transmission electron microscopes are a versatile tool for many fields, including medicine, biology, nanotechnology, metallurgy, forensics, electronics, material science, and much more. A biologist might use a TEM to look at the internal structure of a cell.
b. Industries including microelectronics, semiconductors, medical devices, general manufacturing, insurance and litigation support, and food processing, all use scanning electron microscopy as a way to examine the surface composition of components and products.
c.Brightfield Microscope is used in several fields, from basic biology to understanding cell structures in cell Biology, Microbiology, Bacteriology to visualizing parasitic organisms in Parasitology. Most of the specimens to viewed are stained using special staining to enable visualization.
d.A dissecting microscope is used to view three-dimensional objects and larger specimens, with a maximum magnification of 100x. This type of microscope might be used to study external features on an object or to examine structures not easily mounted onto flat slides.
