Answer:
The correct option is A. Coal use in steam engines led to easier access to goods.
Explanation:
Coal is used in steam engines as a fuel. Coal is one of the cheapest source of energy and hence it has been serving mankind with various benefits since a long period of time.
The coal-based steam engines played a very important role in the developments made during the Industrial Revolution. Many industries started using coal as a power material and made progress.
The steam engines made it possible to transfer goods from one place to another very easily. As coal was a cheap source, hence trading of goods by steam engines was not very costly.
Explanation:
High-energy electrons are transported from the chlorophyll to other molecules by electron carriers beginning with pheophytin, P0 (a form of chlorophyll), then A1 phylloquinone etc.
The chloroplast is an organelle attached to the membrane found in plants. This comprises many plasma membrane invaginations called the thylakoid membrane. It contains chlorophyll pigments, called granum in rows, while the organelle's internal areas are called the lumen. Water fills the granum and the stroma is created.
Further Explanation:
<em>During the light reaction: </em>
- Photosystem II (PSII) contains pigments which consume light energy. This energy is exchanged between pigments until it enters the reaction core and is moved to P680; this transfers an electron to a higher level of energy where it then travels to a molecule of acceptors.
- For those removed from photosystem II, water supplies the chlorophyll in plant cell with substitute electrons. Additionally, water (H2O) divided into H+ and OH-by light during photolysis acts as a source of oxygen along with functioning as a reducer.
- The electron moves down the electron transport chain via several electron carriers
- The e- is delivered (to PS I) where it has a continuous loss of energy. Such energy drives the drainage of H+ from the stroma to the thykaloid, which results in a gradient creation. The H+ pass down their curve, passing into the stroma by ATP synthase.
- ATP synthase converts ADP and Pi to the ATP molecule, which stores energy.
- The electron enters Photosystem I where it heads to P700 pigments. It's. This consumes light energy, transfers the electron to a higher energy level, and moves it on to an acceptor electron. This leaves room for another electron which is then replaced by a photosystem II electron.
- In the ETC the NADP molecule is reduced to NADPH by supplying H+ ions. NADP and NADPH are vital to the Calvin cycle, in which monosaccharides or glucose-like sugars are produced after several molecules have been modified.

Answer:
begins even before the introduction of photography
Explanation:
cameras evolved from the camera obscura though many generations of photographic technology
A scientific hypothesis must be testable and yield results. It must state the intended or predicted result of the experiment
Answer:
You will have to find many different methods in which the resource is most useful. Some resources may be useful in one place and some may be useful in another its all about how you use the resource.
