Compare and contrast the structures and functions of DNA, mRNA, and tRNA

1 answer:

7 0

In DNA the sugar used is called deoxyribose whereas in RNA the sugar is ribose (hence DNA and RNA). The important structural difference between the two types of RNA is that mRNA takes on the shape of a line whereas tRNA has a clover-like shape.

Peat is a mixture of partially decomposed plant and animal material found in waterlogged, acidic, anaerobic environments. people

Verizon [17]

because the total time for restoration is lengthy, peat can be considered a fossil fuel. The correct option is B.

<h3>What exactly are fossil fuels?</h3>

Fossil fuels are fuels derived from the remains of dead plants and animals that decomposed over time under intense heat and pressure.

Because their replenishment time is longer than a human lifetime, fossil fuels are non-renewable energy sources.

Some examples of fossil fuels are petroleum, coal, etc.

The missing options of the question are:

peat is a fossil fuel because rewetting it takes only 3-5 years.
peat is a fossil fuel because the total time for restoration is lengthy.
peat is not a fossil fuel because it has biologic origins, making it a biofuel.
peat is not a fossil fuel because humans can promote the replenishment of peat.

The restoration process of peat takes a long time of more than 100 years. As a result, because the total time for restoration is lengthy, peat can be considered a fossil fuel.

Thus, the correct option is B.

Photosynthesis transforms blank into chemical energy by blank sugars. Cellular respiration releases the blank from food by blank

creativ13 [48]

Photosynthesis and Cellular respiration, both cellular processes are important for life, however, we need to understand what happens to confirm this information....

<h3>Photosynthesis</h3>

Most life on Earth depends on photosynthesis. The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.

Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight. Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color. During photosynthesis, chlorophyll absorbs energy from blue- and red-light waves, and reflects green-light waves, making the plant appear green.

<h3>Cellular respiration</h3>

Cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

One objective of the degradation of foodstuffs is to convert the energy contained in chemical bonds into the energy-rich compound adenosine triphosphate (ATP), which captures the chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.

With this information, we can say that photosynthesis transforms solar energy into chemical energy through sugars. Cellular respiration releases energy from food through sugars.
