When the air pressure within the alveolar spaces falls below atmospheric pressure, air enters the lungs (inspiration), provided the larynx is open; when the air pressure within the alveoli exceeds atmospheric pressure, air is blown from the lungs (expiration).
Answer:
1. It is called the thermosphere because temperatures can reach up to 1,500 degrees Celsius (2,732 degrees Fahrenheit). However, despite the high temperatures, the pressure is very low, so satellites don't suffer heat damage.
2. The physical and biological changes that confirm climate warming include the rate of retreat in glaciers around the world, the intensification of rainfall events, changes in the timing of the leafing out of plants and the arrival of spring migrant birds, and the shifting of the range of some species.
3. Yet history is not the only reason why flood-prone locations are overpopulated. For one thing, rising sea levels and a changing climate are putting more cities' residents at risk. And what's more, new homes are still being built in flood-prone areas around the world.
4. A natural disaster is the consequence of the combination of a natural hazard (a physical event e.g. volcanic eruption, earthquake, landslide) and human activities. ... A natural hazard will hence never result in a natural disaster in areas without vulnerability, e.g. strong earthquakes in uninhabited areas.
5.
Carbon dioxide dissolve readily in sea water hence makes it high in carbonic acid concentration. The fresh water will dilute the concentration of carbonic acid thus preventing the crab from being exposed to high concentrations which can dissolve its shell.

Explanation:
<span>Although it is not mentioned the location, I found the exercise on the internet with the following options:
A)weathering and erosion of park pathways
B)deterioration of the man-made structures in the park
C)pattern and timing of leaf loss in the shade trees
D)exposure of rocks and minerals found in the soil
The only effect, out of this options, that would be studied by biologists is the "pattern and timing of leaf loss in the shade trees". This is the only effect related to life, which is the subject of biology - living organisms and their mechanisms. Leaf loss is a process undergone by many trees as colder seasons, or dry seasons in the case of trees in tropical forests, approach.</span>
Answer:
No
Explanation:
Like I said before in a question similar to this one no it is not alive. Although, Carbon is found in all living things and they move constantly through living organisms, the oceans, the atmosphere, and the Earth’s crust in what is known as the carbon cycle it does not consist of all 7 characteristics that are needed to be considered an organism. For example reproduction and response to stimulus...... it does neither
Answer:
Plants are autotrophs because they can prepare their own food. Photosynthesis takes place in leaves. Leaves contain stomata that allow for the exchange of gases during the process, and also help with the process of transpiration.
