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.
Answer:
the chemicals needed to produce molecules comes from the food which an organism eat.

Answer:
True
Explanation:
Meiosis is a type of cell division that occurs in gametic cells. In this cell division, one cell is divided into four cells and the chromosome number is reduced to half therefore it is also called reduction division.
During meiosis crossing over occurs between homologous chromosomes that allow the exchange of genetic material between them that results in the formation of genetically unique daughter cells.
In spermatogenesis during the first meiosis division, the homologous chromosomes get separated into two daughter cells reducing the chromosome number by half and during second meiotic division sister chromatids separate into two more cells. Therefore four genetically different cells are generated.
The answer is chemical energy
