Which of the following are examples of tissue? (Select all that apply.)
Maurinko [17]

Answer:

Blood and Nerves

Explanation:

Blood is a connective tissue that has a fluid matrix, called plasma, and no fibers. Erythrocytes (red blood cells), the predominant cell type, are involved in the transport of oxygen and carbon dioxide. Also present are various leukocytes (white blood cells) involved in immune response.

Nervous tissue is one of four major classes of tissues. It is specialized tissue found in the central nervous system and the peripheral nervous system. It consists of neurons and supporting cells called neuroglia. The nervous system is responsible for the control of the body and the communication among its parts.

Researchers have crossed two true-breeding lines of peas that differ in the color of their leaf tissue: dark green vs pale green
amid [387]

Answer:

150 individuals

Explanation:

If the dark phenotype is determined by a dominant allele at a single locus, the ratio of dark green phenotype to pale green phenotype at F2 should be 3:1 according to the Mendelian standard.

200 to 3:1 = 150:50

<u>Hence, if 200 F2 individuals were characterized, one would expect the number of dark green individuals to be 150 while the pale green would be expected to be 50.</u>

There are two properties that affect the conduction speed of an action potential along an axon: die axon's diameter and whether
Rom4ik [11]

Answer:

 Axons with high  diameter, and myelinated will conduct action potential faster.

Axons with low diameter but myelinated will be  relatively  slow in the speed of action potential transmission

Axons with high diameter and unmyelinated will be relatively slow in action potential transmission.  

Axons with low diameter, and unmyelinated will conduct action potential slowly .

Explanation:

Diameter of Axon affects conduction speed of Action Potential; the thick axons with  high diameter conducts action potential at a faster speed than thin neurons. This is because of the less resistance to the transmission of action potential along the thick axon. However, thin neurons with   lower diameter has more resistance to the action potential conduct along the axon, thus the speed of transmission is slow.  

Myelinated neuron transmits action potential faster because of   jumping of action potential at the nodes of Ranvier where there is highest concentration of all channel proteins and pump proteins, Therefore action potential is conducted at a faster rate as it jumps from one node to another. This is salutatory conduction. It increases the conduct about 50 times compare to unmyelinated neuron. In neuron of human it increases the speed to 100ms-1

.Conversely, unmyelinated neurone  conducts action potential slowly. About 0.5ms-1 . This is because no salutatory conduction takes place because there is no myelin interruption as Nodes of Ranvier
