Answer:

Both have two circuits for circulation.

Explanation:

  • The two circuits of circulations are known as the systemic circuit and the pulmonary circuit.
  • In the<u> systemic circuit</u>  oxygenated blood from the heart is pumped to all parts of the body through the blood vessels and then the blood is pumped back to he heart.
  • In the<u> pulmonary circuit</u>  deoxygenated blood from all parts of the body is pumped from the heart to the lungs to be oxygenated and after it is oxygenated it is pumped back to the heart.

Time on earth is divided into 6 eras. Three are considered "Precambrian" Which eras are NOT Precambrian?
bulgar [2K]

Explanation:

<u>the  Paleozoic Era </u>

The Precambrian era describes a period of time that pre-dates Cambrian. This time typically references the entire period of the history of earth before the formation of rocks containing identifiable fossils occurred. It covers the majority of Earth’s history and is divided into the Hadean, Archean and the Proterozoic era.

Just before the Cambrian eruption, in the  Paleozoic Era the environment was oxygenated, culminating in an explosion of new life in the Proteozoic Eon (2500-541 million years ago) in the form of primitive blue-green algae named cyanobacteria and oxygen based species. Multicellular species followed later, along with structure at higher levels, and complex life. Oxygen levels grew gradually over this period of time, from low levels.

2. When diffusion has reached equilibrium, we say that
madam [21]

Answer:

See Below.

Explanation:

The key word here is <em>net. </em>The net movement has reached zero when a system is in equilibrium but there are still motion's going back and forth due to statistics and just random brownian motion.

Think of it this way, if there are 100 people walking forwards in a crowd but 2 are moving against the crowd, the net movement is still forwards because the bulk of people are going in that direction. However, there are still 2 people moving against.

Same here, if we are talking about a diffusion, let's say in the case of osmosis, if most of the solute is moving across a membrane then we'd say its net direction is that way but that doesn't mean that there aren't processes happening in the other direction. Water molecules in osmosis mostly diffuse, chemically speaking (because you can say this biologically in a different way), from the probability of water molecules colliding with each other and passing the membrane so even if there is a net movement in a certain way their random motion can make them go to the other side just as well. If the fact that motion stops at equilibrium were the case a lot of systems, both chemical and biological, would not exist as we know it.

Think net = bulk <u>NOT</u> <em>total</em> or <em>entire.</em>
