Answer:
Migration is when animals move on a regular cycle. For example, caribou in the Arctic go south in winter and return in summer when it's warmer. Many birds migrate, such as geese and storks. Migration is the travelling of long distances in search of new habitat.
Explanation:
Answer:d
Explanation:only plants have cell walls
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.
The organisms that would most immediately be affected by acid rain would be phytoplankton in lakes. What would then occur would be diminished insect populations which use phytoplankton as a food source, and then to larger animals like frogs and other insect eating animals. As the interdependence of the food web relies on all these organisms to be in balance, the imbalance that is created by the introduction of acid rain into any part of the food chain will have effects on the entire food web.
