What elements are needed to carry out photosynthesis? Select all that apply.
Answers
Answer:
You need carbon dioxide, sunlight, and water.
Explanation:
Answer:
1.
1.Light or photochemical reactions.
They require the presence of sunlight, which is transformed into chemical energy usable by organisms in the form of ATP, these reactions occur in thylakoids, and for their more detailed study, photochemical reactions are classified as cyclic photophosphorylation and non-cyclic photophosphorylation.
2.Carbon fixation reactions or reactions in the dark.
They require or not the presence of sunlight, and they are reactions that will occur in the stomata.
3.Chemosynthesis.
They take inorganic compounds and O2 from the environment and combine them inside their cells and as a result of these reactions energy is released (exergonic reactions) applying it in the synthesis of ATP (endergonic reactions), forming inorganic by-products.
Biological importance of photosynthesis:
Photosynthesis is surely the most important biochemical process in the biosphere for several reasons:
1. Every year some 200,000 million tons of carbon is used in the photosynthetic process.
2. The synthesis of organic matter from inorganic is carried out mainly through photosynthesis; that will go from some living beings to others through the food chains.
3. Produces the transformation of light energy into chemical energy, necessary and used by living beings.
4. Oxygen is released, which will be used in aerobic respiration as an oxidant.
5. It is the cause of the change produced in the primitive atmosphere, which was Anaerobic and reductive.
6. The energy stored in fossil fuels such as Coal, Oil, and Natural Gas also depends on it.
7. It is responsible for maintaining the necessary balance between Autotrophic and Heterotrophic beings.
8. During the process, dioxygen is released into the atmosphere, which implies:

Which space telescope is used to see distant objects?
The Hubble Space Telescope, often known as HST or Hubble, is an observatory that was put into low-Earth orbit in 1990 and is still in use today.Although it wasn't the first space telescope, it is one of the biggest and most useful ones. It is famous for being both an essential scientific tool and a public relations success for astronomy.The only telescope made with astronaut maintenance in mind is Hubble. Five Space Shuttle trips have been used to replace, improve, and repair the telescope's systems.Since Hubble is orbiting outside of Earth's distorted atmosphere, it can take extraordinarily high-resolution pictures with a lot less background light than ground-based telescopes can.The Hubble telescope and other space telescopes can be used to zoom at distant objects.

What are the qualities of greenhouse gas? Select the two correct answers.
A. transparent to infrared radiation
B. three or more atoms in a molecule
C. produced by human activity
D. absorbs and re-emits infrared radiation
E. composed of single atoms, not molecules
Answers
I agree with the user's answer above ^. I think both choices suit the qualities of a greenhouse gases. So, yes 'absorbs and re-emits infrared radiation' and 'transparent to infrared radiation' are correct.
Infrared radiation is emitted by greenhouse gases. Therefore, option"A" is correct.
What are greenhouse gases?A gas that can absorb infrared light is referred to as a greenhouse gas. Only molecules with three or more atoms have the capacity to absorb infrared light. Homonuclear diatomic molecules like N2 and O2 don't absorb or emit infrared light because their dipole moments don't alter much.
The quantities of greenhouse gases are influenced by numerous factors. Fossil fuels release CO2 . Since the Industrial Revolution, human activities, particularly the burning of fossil fuels, have led to persistent increases in the atmospheric concentrations of different greenhouse gases, including carbon dioxide, methane, ozone, and chlorofluorocarbons (CFCs).

It needs to be revisited because of the random acts of violence that it enables.
Explanation:
People that have access to weapons of mass destruction use them to kill people for no reason. For example, the sandy hook shooting, the recent Stoneman Douglas shooting, and the Christchurch shooting. All these shootings could have been prevented if there was stronger gun control.
