6. I don't know this one, sorry.
Explanation:
Answer:
1.) Water; carbon dioxide
2.) Sugar; oxygen
3.) Pigment
4.) An electron
5.) ATP, NADPH, and oxygen
6.) NADP+
Explanation:
The photosynthesis chemical equation states that the reactants (carbon dioxide, water and sunlight), yield two products, glucose and oxygen gas. Molecules called pigments absorb energy from light. The main pigment in photosynthesis is called chlorophyll. Chlorophyll exists in several different forms in different organisms. Chlorophyll a is the main photosynthetic pigment found in land plants and algae. A photon of light energy travels until it reaches a molecule of chlorophyll. The photon causes an electron in the chlorophyll to become “excited.” The energy given to the electron allows it to break free from an atom of the chlorophyll molecule. Chlorophyll is therefore said to “donate” an electron. In light-dependent reactions, the energy from sunlight is absorbed by chlorophyll and converted into chemical energy in the form of electron carrier molecules like ATP and NADPH. The final electron acceptor is NADP. In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product.

why are antibiotics unhelpful for treating the common cold?
Antibiotics unhelpful for treating the common cold because they only fight bacteria, not viruses. However, a cold can sometimes result in a bacterial infection. In that case, antibiotics would be beneficial if they could prevent that type of infection.
ANTIBIOTICSAntibiotics are medications that aid in the prevention of bacterial infections. They accomplish this by either killing the bacteria or preventing them from replicating or reproducing themselves.Antibiotics are drugs that kill germs in your body. However, most people use the term when referring to antibiotics.Answer:d

What would happen to a phospholipid bilayer if the phosphates instantly lost their charge?
I
Answer:
The phosphate group is the negatively-charged and polar head present in the phospholipid bilayer.
The phosphate group is attracted to water in the intracellular fluid in the phospholipid bilayer and helps to maintain the fluidity of the bilayer. if phosphates instantly lost their charge then it will lose its attraction towards an intracellular fluid and phospholipid bilayer will lose its bilayer structure.

Overfishing is causing the decline of fish populations, such as Eastern Atlantic bluefin tuna in the Mediterranean. Eastern Atlantic bluefin tuna are caught faster than they can reproduce. Which statement describes themost likely effect that overfishing will have on this ecosystem?
Overfishing decreases the stability of the ecosystem by disrupting food chains.
How does overfishing affect the environment?The fishing enterprise affects a number of marine preservation issues, including fish populations, water pollution, and habitat degradation.
Some investigators have claimed that the size of the fishing industry needs to be seriously decreased in order to maintain healthy marine environments around the world.
Thus, Overfishing decreases the stability of the ecosystem by disrupting food chains.

https://brainly.com/question/5142437
Overfishing of Eastern Atlantic bluefin tuna in the Mediterranean is likely to result in decreased ecosystem stability due to disruptions in food chains and ecological balance. Thus correct option is A.
By significantly diminishing the population of a crucial species, such as the Eastern Atlantic bluefin tuna, overfishing has the potential to upset the ecosystem's delicate equilibrium.
Being the top predators that they are, the reduction of these tuna might result in an increase in the population of their prey, which would have a ripple effect across the entire food chain. This imbalance may lead to resource depletion, an overabundance of some species, and ultimately the instability of the entire ecosystem.
The most likely impact of overfishing on the environment is, in essence, option A. It's crucial to keep in mind that ecosystems are intricate, interconnected systems, and that the eradication or decline of one species may have reverberating consequences on the entire biological web.

What is the environmental impact of allulose sugar?
Commercial allulose is most often derived from corn, long criticized as an industrial farmed monocrop that rapidly depletes both water supplies and soil health. Once the corn is grown and harvested, it gets fermented to pull out the fructose. From there, enzymes (often proprietarily created by various allulose manufacturers) are added to convert the fructose to allulose. Even if these manufactures are using solar power to offset carbon producing energy costs, and many are, with marketing surveys showing that 7 out of 10 people worldwide are looking to reduce their sugar intake, the fossil fuel energy required make the allulose to fill that need, is still likely to be significant. At this point in time, this eater is going to plan to reduce her sugar intake by just not having it. And when I do want something sweet, I’m going to stick to Maine maple syrup as my local sugar alternative.

Melinda had two slides of unknown cells. She recorded her observations of each one on the chart below.
According to the information in the given chart, what type of cell is cell X?
a
prokaryotic cell
b
bacteria cell
c
animal cell
d
plant cell
Answer:
According to the information given by Melinda on the chart, about the observed cells, cell X is an animal cell.
Explanation:
Animal cells are eukaryotic cells, with the ability to differentiate and unite to form tissues.
An animal cell contains elements such as a cell membrane, cytoplasm, nucleus and organelles —including mitochondria— by which it can be identified and differentiated from other cell types.
An important feature of animal cells is the existence of cytoplasmic compartments that form the endomebrane system, in relation to the cytoplasmic membrane and organelles.
The other options are not possible because:
Bacterial and prokaryotic cells lack nuclei and organelles. Plant cells possess chloroplasts and cell wall, as described for the Y cell.What is a variation for a shark
