A compound microscope has multiple lenses: the objective lens (typically 4x, 10x, 40x or 100x) is compounded (multiplied) by the eyepiece lens (typically 10x) to obtain a high magnification of 40x, 100x, 400x and 1000x. Higher magnification is achieved by using two lenses rather than just a single magnifying lens.
Answer:
B. Resources such as time and energy are limited, so survivorship and fecundity cannot both be maximized simultaneously.
Explanation:
Each species trade-off between the survival and the life history traits such as a number of offspring produced, parental care and frequency of reproduction. Both reproductive success (fecundity) and survival success cannot be maximized due to limited resources.
For instance, species such as mosquitoes spend minimum energy is parental care but produce a large number of relatively unprotected young ones when the growth conditions become favorable to ensure the continuity of the species. They cannot spend much time in acquiring reproductive maturity and post natal care due to a small period of favorable growth conditions. On the other hand, most of the mammals such as human beings spend their energy in pre- and postnatal care to their young ones.
The Rocky Mountains are a major mountain range located in the American Midwest that span more than 3000 miles. both a and c are correct. They are not part of the grand canyon.
UV.
The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. This energy with wavelengths too short to see is "bluer than blue". Infrared radiation has a longer wavelength than visible red light.
A neuron is a specialized cell, found in the brain, spinal cord and the peripheral nerves known as the nerve cell. The structure of a neuron varies with their shape and size and it mainly depends upon their functions
<h3>what is the structure of neuron ?</h3>
Dendrites which is A branch-like structure that functions by receiving messages from other neurons and allow the transmission
Cell Body has a cell body with a nucleus, Golgi apparatus, endoplasmic reticulum, mitochondria and other components.
Axon is a tube-like structure that functions by carrying an electrical impulse from the cell body to the axon terminals
Synapse functions by permitting the entry of a neuron to move an electrical or chemical signal from one neuron to another neuron.
