1). Under Classifying Life, click Launch Interactive. Scientists use a tool called a phylogenetic tree to show the evolutionary pathways and relationships between organisms. A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms.
2). Sometimes referred to as DNA-DNA hybridization, this process hybridizes the genetic information from two different organisms to determine similarities between them. Scientists separate strands of DNA from both species using heat, which breaks the bonds between the base pairs that link the two sides of the double helix.
Answer:
The correct answer is : The concentration of solute in the environment is equal to the concentration inside the cell.
Explanation:
Isotonic environment is an environment the amount of solute concentration is equal on both side of the semipermeable membrane or the cell. in such condition there would be no water movement towards particular direction or will take place and as there is no water movement so there would be no change in shape or size of the cell. The osmotic pressure in an isotonic environment would be same on both side of the membrane.
Thus, the correct answer is : The concentration of solute in the environment is equal to the concentration inside the cell.
Answer:
a. every muscle has a varying number of motor units so they can generate different frequencies.
e. each motor unit can innervate a different number of muscle fibers.
Explanation:
Electromyography (EMG) is a diagnostic procedure used to measure the response of muscles and nerves to electrical activity. A motor unit is composed of one motor neuron and muscle fibers it innervates. The number of muscle fibers in each motor unit can vary among different muscles and even among motor units within the same muscle. Each motor unit is known to innervate a variable number of muscle fibers, but each single muscle fiber is innervated by only one motor.
Answer:
Saudi Arabia is a major producer and supplier of oil, a major energy source. Thus, the statement "The Great Plains states have been
called the Saudi Arabia of wind energy" simply means that the output of wind energy from the Great Plains is massive.
