Which of the following molecules is the primary product of photosystem I?a) Carbon dioxideb) Oxygenc) NADPHd) ATP
Lina20 [59]

<u>Answer:</u>

The primary product of the photosystem I is NADPH.

<u>Explanation: </u>

NADPH is the acronym of Nicotinamide adenine Dinucleotide Phosphate. This NADPH plays a vital role in many chemical reactions that take place during  photosynthesis process. NADPH is released as a product in Photosystem I.

In the photosystem I process, the molecule present will absorb sunlight energy and transfers it to electrons to produce NADPH. This NADPH molecule is used as fuel for the chemical process that occurs during the 2nd stage of the photosynthesis process. Its molecular formula is C_{12} H_{30} N_{7} O_{17} P_{13}. It acts as a fundamental metabolite.

Which of the following statements about photophosphorylation is FALSE? Energy from oxidation reactions is used to generate ATP f
kolbaska11 [484]

Answer:

The FALSE statement is: It requires CO2.

Explanation:

Photophosphorylation is a process during which solar energy, in the form of a proton, impact on chlorophyll, exciting one electron. The excited electron pass along different carriers (Ferredoxin, cytochrome b6f and Plastocyanin) and eventually return to its origin. This electron passage promotes the formation of ATP from ADP (one molecule ATP is formed when three electrons pass throug the cycle).

What is sandy soil? which crops are suteble to grow in sandy soil
Viktor [21]
<h3>Answer:</h3><h3>Sandy Soil is light, warm, dry and tend to be acidic and low in nutrients. Sandy soils are often known as light soils due to their high proportion of sand and little clay (clay weighs more than sand). These soils have quick water drainage and are easy to work with.</h3><h3>Explanation:</h3><h3>CARROTS </h3><h3>Carrots have tap roots, which means that carrots grow better when their root systems can easily penetrate the ground. That need for depth makes sandy soil a perfect medium for growing carrots. Clods of soil, like those present in clay-based soil types, can impede and disrupt the development of carrot root development. </h3><h3> </h3><h3>RADISHES </h3><h3>Like carrots, radishes also have tap roots, which need to be able to easily burrow into the ground. Sandy soils are porous and more malleable than clay-based mediums, so they are therefore suited to be a habitat for radishes, carrots, and other root vegetables. </h3><h3> </h3><h3>POTATOES </h3><h3>Potatoes are another root vegetable that thrives in sandy soil. This is mainly because sandy soils have an acidic soil pH balance. Acidic soils eliminate the possibility of scab, a disease that plagues potatoes, often affecting entire crops. </h3><h3> </h3><h3>LETTUCE </h3><h3>Lettuce, more than many other leafy green vegetables, tends to tolerate the dryness of sandy soils as long as gardeners make sure that plants are watered daily and regularly, never allowing the soil above the roots to completely dry out. Hydration is especially on abnormally hot or windy days.  </h3><h3> </h3><h3>COLLARD GREENS </h3><h3>Like lettuce, collard greens are able to tolerate the dry conditions of sandy soils better than other leafy greens. Collards also perform well in the early spring, which makes them more suited for sandy soils, which warm up faster than clay-based or loam-based soil types. </h3><h3> </h3><h3>TOMATOES </h3><h3>Tomatoes are sun-loving fruits that perform exceptionally well in the heat-retaining, well-draining habitat that sandy soils provide. Though they’re sometimes grown as annuals in the summer, tomatoes are usually grown as perennials that are harvested throughout a long growing season.  </h3><h3> </h3><h3> </h3><h3>ZUCCHINI </h3><h3>Zucchini is an annual summer crop and a heavy feeder that enjoys the warmth and excellent drainage of sandy soil habitats. As long as the plant’s fertilizer needs are met when it’s grown in sandy soil, zucchini will produce fruit that can be harvested in abundance. </h3><h3> </h3><h3>CORN </h3><h3>Like zucchini, corn is a heavy-feeding annual summer vegetable that thrives in sandy soil as long as it is well fertilized.   </h3><h3> </h3><h3>ASPARAGUS </h3><h3>Grown best from the crowns in a sandy soil medium, asparagus is well-suited to growing in trenches. Use bone meal or rock phosphate to fertilize your asparagus twice per week when growing in sandy soils for the highest yields. </h3><h3> </h3><h3>WATERMELON </h3><h3>Watermelon requires a longer growing season than other fruits of its type but enjoys the warmth and well-draining environment that sandy soil provides. Just make sure you provide sufficient space between plants for each watermelon to develop, as these plants will only thrive if they are not having to battle other plants for water and nutrients. </h3><h3> </h3><h3>BEANS </h3><h3>Though beans do best in a loose, well-draining soil, such as a sandy one, be sure to add in lots of compost to your sandy soil before planting beans for maximum yield.  </h3><h3> </h3><h3>CUCUMBER </h3><h3>Cucumbers need fast-draining soil to thrive, so a sandy medium is a great fit. However, you will need to go the extra mile in providing lots of water and nutrients for your cucumbers to keep them happy. A trellis must also be provided to give the cucumber vine a support to attach itself to and grow upon.</h3>
