Secretion is the process in urinary system that leads to the elimination of excessive substances like sodium and potassium in the urine.

Secretion is the process of transfer of waste substances from the blood capillaries into the renal tubule. The waste substances can be ions like sodium, potassium, or hydrogen. The segment of the renal tubule that performs secretion is the proximal convoluted tubule.

Urinary system is also called the excretion system where all the waste ions, minerals and water is transferred out from the body in the form of urine. Kidneys are the key organs of the urinary system. They filter out the impurities from the blood and excrete it out through the urethra by a process called micturition.

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

What happens during the first two stages of cellular respiration?
Artemon [7]

Answer:

Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. ... Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.

Clasificación bacteriana​
Nimfa-mama [501]

Answer:

Formas: todas las bacterias se pueden clasificar en una de las tres formas básicas: esferas (cocos), bastones (bacilos) y espirales o hélices (espiroquetas). Necesidad de oxígeno: las bacterias también se clasifican en dos grupos, según si necesitan oxígeno para vivir y crecer o no les es necesario.

State the two components of natural capital.
Mademuasel [1]

Answer:

I think

Abiotic natural capital comprises subsoil assets (e.g. fossil fuels, minerals, metals) and abiotic flows.

Biotic natural capital or ecosystem capital consists of ecosystems, which deliver a wide range of valuable services.

Hope this Help!:)
