the data collected over the years clearly confirm depletion of ozone in the stratosphere. what do scientists still need to learn

Answer:

Ozone is the layer (blanket) on the atmosphere that protects lives on earth, from the harmful incoming ultraviolet solar radiation. This are UV rays can damage the skins of humans. It is denoted by O₃ and is located at the stratosphere.

This ozone layer has been significantly affected due to the emission of green house gases. The use of chlorofluorocarbon (CFC), methane gas (CH₄) as well as emission of carbon and sulfur has depleted the ozone layer.

<u>Scientists have studied and examined why this depletion is going on and have suggested many steps to avoid ozone depletion and are still trying to find out the best solution to stop this ozone depletion. The use of products that contains CFC and releases methane gas must be avoided</u>.

The ozone depletion is observed to be maximum in Antarctica because the environment there is suitable for the events that leads top the depletion of the ozone layer.

<span>Ozone is simply a molecule consisting of 3 oxygen atoms, which reacts strongly with other molecules. Ozone is created in the stratosphere when high energy uv radiation causes on O2 molecule to split. The free oxygen atoms collide and react with other O2 molecules to form O3.</span>

Production is highest where the solar uv is the greatest eg near the tropics, but once created, the ozone is then circulated towards the poles by the atmosphere. The amount of ozone in the stratosphere can vary with location, season and even day to day climatic conditions.

<span>The process of ozone creation is what makes the O3 in the atmosphere very effective at shielding the Earth from harmful uv radiation, which can cause many biological problems, such as skin cancer. However, due to its high reactivity, the uv found in the tropospher at ground level can aslo be dangerous as a toxic pollutant which is harmful to plants and lung tissue, and is a major cause of smog.</span>

When mammals get an infection, their internal body temperature often rises 2 to 3 degrees Celsius. The body gets the energy it n
Paladinen [302]

Answer:

The correct answer is increasing the rate of cellular respiration in mitochondria.

Explanation:

In mammals like humans, the infection causes a rise or hike in the body temperature of an individual up to 2 - 3 degrees Celsius. Infection results in thermoregulation strategies control by the hypothalamus, of the host by immune system transmitted integration signals, hormonal and neuron lead and increase in metabolic reactions by the increase the rate of the cellular respiration takes place in the mitochondria and that elevate body temperature. Mitochondria releases energy in the form of ATP that helps in body temperature as it is an exothermic reaction.

The correct answer is increasing the rate of cellular respiration in mitochondria.

Suppose that a late succession plant that is surrounded by early succession plants grows at a rate of 0.5 cm per day. If the ear
inessss [21]

Answer:

negative, inhibition

Explanation:

The experiment in the illustration shows that early succession plants have a <u>negative </u>effect on the late succession plants, and the observation is most consistent with the <u>inhibition</u> model of succession.

<em>That the late succession plant thrives better in the absence of the early succession plants means that the early succession plant has been impacting the growth of the late succession plant negatively. This is consistent with the inhibition model of succession.</em>

There are 3 different models of succession. These include;

  1. Facilitation model in which colonists modify the environment to favor the growth of later successional species.
  2. Tolerance model in which early colonists' modification of the environment has no positive or negative impact on the growth of later successional species.
  3. Inhibition model in which early colonists modify the environment to inhibit the growth of later successional species.

why does the presence of 22 large herbivore species at Mpala seem to contradict the competitive exclusion principle Dr. Pringle
stealth61 [152]

Dr. Pringle suggests that there's only very few large herbivorous species that can survive in certain area. The reason behind his claim is that according to him there will be only enough food for few large species, so there's natural limitations in the food sources, as there should be enough to support them in order for them to survive.

On the other hand, in Mpala, there's 22 large herbivorous species, which directly contradicts Dr. Pringle's hypothesis. The reason why so many large species of herbivores an survive in Mpala and always have enough food for all of them, is that they have all specialized in eating certain types of plants or parts of plants, thus they are not direct competition to one another, and there's always enough food for all of them.

In photosynthetic cells, synthesis of atp by the chemiosmotic mechanism occurs during _________.
NikAS [45]
In photosynthetic cells, synthesis of ATP by the chemi-osmotic mechanism occurs during photosynthesis and respiration. Plants can only achieve photosynthesis during the day and then respire during the night because photosynthesis requires the sun's energy to perform the necessary reaction to produce oxygen.
