The answer is between A and C.
Answer:
21 m
Explanation:
La energía potencial de un cuerpo es la energía que posee el cuerpo en virtud de su posición.
La energía potencial se da como;
E = mgh
Dónde;
m = masa del cuerpo
g = aceleración por gravedad
h = altura del cuerpo
Aquí necesitamos obtener la altura del cuerpo.
h = E / mg
h = 10500/50 * 10
h = 21 m
Fundamental niche is the job/role that one species can have in the environment .
The realized niche is the role of a species influenced by several factors in the environment.
Example:
The fundamental niche of Yellow Warblers is found in a spruce tree.
The realized niche of the Yellow warblers is when they are "forced" to share the spruce tree and remain in one particular area of the tree while other warbler species play defense different niches in other parts of the tree.
:v it is like :
•Fundamental niche: [yellow warbler] "I got my home, all for me..."
~new species arrive to the spruce tree~
•Realized niche: [yellow warbler] oh, shoot! I gotta stay in the upper part/move to the upper part as the others warbler "struggle" to get territory :v or they just choose their own . :v
Answer:
Homeostasis is the process of maintaining a constant internal environment of the body with the help of certain mechanisms such as feedback loops.
Explanation:
Homeostasis refers to the maintenance of a relatively constant internal environment of the body. It includes maintaining several parameters such as acid-base balance, blood glucose level, body' temperature, etc. within the narrow range.
Homeostasis is mainly maintained with the help of negative feedback loops wherein the deviation of any parameter from the normal physiological range is counteracted and restored.
For example, the blood glucose level remains within the range of 70 and 110 milligrams of glucose per 100 milliliters of blood under normal physiological conditions. Any deviation from the range is restored with the help of pancreatic hormones insulin and glucagon.
Microscopes have been used for centuries in order to see specimen scientists cannot see with their unaided eye. Antón VanLeeonhoeuk is given credit for designing the first lenses for microscopes in the 16th century. He looked at “animacules” which we would now call bacteria and protists. Robert Hooke first coined the term cell, as he looked at cork and thought it looked like cells that monks slept in. Improvements were made in the following centuries, and Ernest Leintz in the 1800s creates a way to have differing magnification lenses on one microscope. Continuing into the 1900s and 2000s there are now electron scanning microscopes, ultraviolet microscopes, atomic force microscopes, and electron tunneling microscopes—all which allow scientists to have better resolution and to see smaller and smaller things. Microscope technology will continue to improve as scientists discover more ways to magnify the microscopic world.
