Answer:

The tree is the autotroph.

Explanation:

First, let's define what autotrophs are.

Autotrophs are organisms that make their own food, not relying on other organisms to eat.

Now let's explain why trees are the answer.

Trees use photosynthesis to make their own foods in the form of glucose (or sugar). The plant then uses these to sustain themselves. This process makes them an autotroph.

Answer:

Pretty sure its a tree, an autotroph is an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide. which would be a tree

Explanation:

Desalination is a process that takes away mineral components from saline water. More generally, desalination refers to the removal of salts and minerals from a target substance

Answer:

True.

Explanation:

The chloroplasts' function is to take energy to perform photosynthesis. That is why there are no chloroplasts in animal cells.

Answer:

True

Explanation:

Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.

In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

Answer:

The answer would be A. The claims are based on empirical evidence and are likely to be pseudoscientific. They are not particularly useful

Explanation:

hope this helps

The claims are based on empirical evidence and are likely to be pseudoscientific. They are not particularly useful. Therefore, option A is correct.

A statement, discovery or explanatory system that is presented as pseudoscience lacks the objectivity required by the scientific process. Research that is based on dubious ideas, a defective experimental design, or unreliable data can also lead to pseudoscience.

Pseudoscience may be presented in good faith due to incomplete or inaccurate data analysis. However, it is also possible to deliberately apply scientific methods incorrectly in order to instill unjustified confidence in conclusions that would not be supported by a more rigorous approach.

These claims are pseudoscientific. Hence, option A is correct.

Which characteristic best explains why lotic ecosystems tend to have more dissolved oxygen than lentic ecosystems?

⋆Lotic ecosystems tend to be warmer, which increases dissolved oxygen levels.

⋆Lentic ecosystems contain still water, which decreases the solubility of oxygen. ✓

⋆Lentic ecosystems tend to have a larger variety of species using up the oxygen.

⋆Photosynthetic organisms use most of the dissolved oxygen in lentic ecosystems.

The characteristic that best explains why lotic ecosystems tend to have more dissolved oxygen than lentic ecosystems is lentic ecosystems contain still water, which decreases the solubility of oxygen. The correct option is b.

Lotic ecosystem refers to environments with flowing water, such as rivers and streams, lentic (from the Latin lentus, meaning sluggish or motionless), refers to standing waters such as lakes and ponds (lacustrine), or swamps and marshes (paludal).

Examples of Lentic ecosystems are ponds, marshes, etc. and examples of lotic ecosystems are streams and rivers. Rivers are always moving and ponds are still.

Therefore, the correct option is b. Still, water is a component of lentic ecosystems, which reduces oxygen solubility.

Answer:

Members from 197 nations meeting at the summit of the United Nations Environment Programme in Kigali, Rwanda reached a legally-binding accord to phase out HFCs in an amendment to the Montreal Protocol due to HFCs potential for global warming.

Explanation:      

The Phase-out Management Plan (HPMP) for Hydrochlorofluorocarbons (HCFCs)  

Under the Montreal Protocol on Substances Depleting the Ozone Layer, in particular the Executive Committee (ExCom) 53/37 and ExCom 54/39, the Parties to this Protocol agreed to set 2013 as the time for developing countries to freeze consumption and development of HCFCs. For developing countries, the decline in consumption and production of HCFCs started in 2004 and 2010, respectively, with a decline of 100% set for 2020. Developing countries have agreed to start reducing their HCFC consumption and output by 2015, with a reduction of 100% set for 2030.

Hydrochlorofluorocarbons are a category of man-made compounds containing hydrogen, chlorine , fluorine and carbon, generally referred to as HCFCs. In nature, they are not found anywhere. After countries decided to phase out the use of CFCs in the 1980s, which were found to be damaging the ozone layer, HCFC production began to take off. HCFCs are used for refrigeration, aerosol propellants, foam processing and air conditioning, much like CFCs. However, unlike CFCs, most HCFCs in the lowest part of the atmosphere are broken down and pose a much smaller danger to the ozone layer. Nonetheless, considering their very low atmospheric concentrations, HCFCs are very potent greenhouse gases, measured in parts per trillion. Compared to CFCs with ODP 0.6-1.0, these HCFCs have lower ODPs (0.01-0.5) in terms of ozone depletion potential (ODP). Compared to CFCs with a GWP of 4,680-10,720, HCFCs have lower GWPs (76-2,270) in terms of global warming potential ( GWP).

Hydrofluorocarbons (HFCs), manufactured mostly in developing countries, have replaced CFCs and HCFCs. HFCs do not cause damage to the ozone layer because they do not contain chlorine, unlike CFCs and HCFCs. However, they are greenhouse gases, similar to that of CFCs and HCFCs, with a strong global warming potential ( GWP).

In the other three options ,there is no role of the members from 197 nations meeting at the summit of the United Nations Environment Programme in Kigali.

Hence, the correct option is A.

The role of deep-sea coral reefs in the environment is to provide critical habitat for many other organisms. So, the correct option is C.

A coral reef is an underwater ecosystem characterized by reef-building corals.

Coral reefs provide critical habitat for many invertebrates and fishes. These organisms are also known as cold-water corals, as they are found in the deeper and darker part of the ocean where the temperature is extremely low.

Therefore, the role of deep-sea coral reefs in the environment is to provide critical habitat for many other organisms.

Due to continuous global warming, the oceans tend to gain more heat, and hence the temperature rises. In the current century, the heated conditions of the oceans can be threatful for the human population. Also, the increase in the sea levels will have serious consequences on the health of mankind and their quality of life.

Explanation:

As the overabundance heat and energy warms the ocean, the temperature change causes unprecedented cascading effects such as ice melting, sea-level rise, marine increased temperatures, and ocean acidification.

The massive quantity of carbon dioxide absorbed by the ocean dissolves as carbonic acid in seawater.

This is known as ocean acidification, and it is literally causing a sea change that is threatening the basic chemical balance of ocean and coastal waters from pole to pole.

Changing ocean chemistry, according to laboratory studies, will

As the ocean warms due to an abundance of heat and energy, the temperature change causes unprecedented cascading effects such as ice melting, sea-level rise, increased marine temperatures, and ocean acidification.

Thus, the human population can be widely affected as a result of impacts of climate changes.
