The greenhouse effect is an essential phenomenon for life on earth. However, human activities such as pollution and burning of fossil fuels have caused an intensification of this effect, which has harmed the atmosphere and is directly related to global warming.

The greenhouse effect is formed by a layer of atmospheric gases that settle around the planet and allows a temperature suitable for life to reach the earth's surface. Therefore, we can guarantee that this effect is essential for our survival. It is necessary that the amount of these gases is kept in equilibrium for this temperature to be constant.

However, the burning of fossil fuels, industrial activities, pollution (caused by vehicles, aerosols, fires, among others), the use of non-renewable energy releases greenhouse gases into the atmosphere daily and in large quantities.

This causes the layer of greenhouse gases that circulates the earth to become more and more expanded, not being able to disperse solar radiation easily and causing an increasing temperature. All that heat is retained in the atmosphere, thus generating global warming, which allows the planet's temperature and ocean water to increase dramatically, which can cause various harmful effects to life on the planet.

For this reason, it is necessary to carry out public policies that reduce pollution and encourage the use of clean and renewable energy that does not increase the layer of greenhouse cases, promoting well-being and life on earth.

Internal membrane connected to the external membrane where energy production may occur and which may help cell division
Paha777 [63]
Mitochondria are unusual organelles. They act as the power plants of the cell, are surrounded by two membranes, and have their own genome. They also divide independently of the cell in which they reside, meaning mitochondrial replication is not coupled to cell division. Some of these features are holdovers from the ancient ancestors of mitochondria, which were likely free-living prokaryotes.

Glycolysis is active when cellular energy levels are _____; the regulatory enzyme, phosphofructokinase, is _____ by atp.glycolys
vampirchik [111]
<span>Glycolysis is a process that can be seen as occurring in eukaryotic cells. This process is active when cellular energy levels are low; and the regulatory enzyme is inhibited by ATP. This process releases energy that is labeled as 'free'. After this process the released energy goes to form ATP molecules, which are high in energy.</span>

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>

A continuing-care retirement community

A continuing care retirement community is a community that provides multiple care levels all on one campus. These multiple care levels which could include independent living, assisted living, memory care or skilled nursing and rehabilitation are set up to provide all of the care that one will need throughout his lifetime.  For the question given above, a continuing-care retirement community might be best alternative for this couple because it has the resources and staff available to meet their needs and they can rest easy if their health changes in the future.
