Answer:
10m/s
Explanation:
Given parameters:
Frequency of wave = 2Hz
Wavelength = 5m
Unknown:
Speed of the wave = ?
Solution:
The speed of a wave is derived from the product of wavelength and frequency;
speed = frequency x wavelength
Insert the parameters and solve;
speed =2 x 5 = 10m/s
Answer:
gene pool or gene frequency
Explanation:
Biological Evolution has to do with how a population's gene pool changes over time.
Answer: Hills are elevations of the earth's surface that have distinct summits, but are lower in elevation than mountains. Hills may be formed by a buildup of rock debris or sand deposited by glaciers and wind. Hills may be created by faults. Faults are a slight crack in the earth which can cause earthquakes.
The answer is skeletal muscles. Skeletal
muscle—multinucleated, striated, long cylindrical cells called fibers; located
in deltoid, gastrocnemius, biceps brachii, etc. There are three types of muscle
tissue. Skeletal muscle—multinucleated, striated, long cylindrical cells called
fibers; located in deltoid, gastrocnemius, biceps brachii, etc. Smooth
muscle—no striations, spindle-shaped cells, single nucleus located centrally;
located in wall of arteries, arrector pili muscle, iris, walls of hollow
organs.
Answer:
Embedded in the lipid bilayer are large proteins, many of which transport ions and water-soluble molecules across the membrane. Some proteins in the plasma membrane form open pores, called membrane channels, which allow the free diffusion of ions into and out of the cell.
