How do biological organisms use energy worksheet answer key?

Answer:

B) the correct sequence of amino acids in the synthesized protein.

Explanation:

The given DNA sequence is ATG GCC CAA TCG TGA. Its corresponding mRNA sequence would be UAC CGG GUU AGC ACU.

However, the point mutation has replaced the "C" from forth codon and the mutated codon is "AGU".

Both AGC and AGU code for amino acid "Serine". So, there would not be any change in the amino acid sequence encoded by mRNA which is transcribed from mutated DNA.  

Correct answer: B). It occurs in producers

Breathing is known to be the biological function of the organism that allows the absorption of oxygen from the environment and release of carbon dioxide. It occurs in consumers as well as producers.

Photosynthesis only occurs in the plant also called as producers in which they prepare their own food with the help of carbon dioxide and water in the presence of sunlight.

Hence, the correct answer would be it occurs in Producers.

Answer:

It transports nutrients in the body. It circulates macrophages in the body.

Explanation:

Main functions of lymph is to maintain the fluid balance and absorption and transport of nutrients. Lymph is the fluid of lymphatic system that serves to absorb the digested fats as well as lipid soluble vitamins and transport them to the blood vessels. The white blood cells such as macrophages are transported along with lymph through lymphatic vessels.

The Calvin cycle uses CO2 from the light reactions to make sugars, and the light reactions use the sugars made by the Calvin cycle to make ATP.

To create three-carbon sugars, the Calvin cycle reduces the power of NADPH from light-dependent processes while utilizing the chemical energy of ATP.

The Calvin cycle is a set of chemical events that occur in plants as carbon dioxide is reduced or converted into glucose.

The Calvin cycle, the latter phase of photosynthesis, produces sugars using ATP and NADPH from the light-dependent processes.

The energy-storing two molecules are then used in the light-independent processes.

Therefore, ATP and NADPH are energy molecule is produced during the light reactions and helps to power the Calvin cycle.

The muscle fibres use several substrates in order to perform contractions. ATP is one of them. It binds to the myosin head and causes contraction. Creatine phosphate is another substrate that works in the "background" storing energy to convert ADP into ATP quickly as ATP is being used. Glycogen is another of the muscle fibres' substrates. It's used to produce energy quickly when creatine phosphate runs out of phosphates to use on ADP. The use of glycogen leads to the deposition of lactic acid on the muscles.

When these substrates run low there is muscle fatigue (or also called, in this case, metabolic fatigue) - there's no energy. Another cause may be from the deposition of lactic acid that also leads to such fatigue.

Matter is defined as anything that has mass and occupies space. This includes solids, liquids, and gases. Elements, which are pure substances that cannot be broken down by ordinary chemical means, are the building blocks of matter.

Matter is defined as anything that occupies space and has mass, and it is all around us. Solids, liquids, and gases are all forms of matter. We can see that solids and liquids take up space, and their weight tells us that they have mass. Gases are also matter; if gases did not take up space, a balloon would not inflate (increase its volume) when filled with gas.

The substance of the universe from a grain of sand to a star-is called matter. An object's mass is the amount of matter contained in the object, and the object's mass is the same whether that object is on Earth or in the zero-gravity environment of outer space. An object's weight, on the other hand, is its mass as affected by the pull of gravity.

All matter in the natural world is composed of one or more of the 92 fundamental substances called elements. An element is a pure substance that is distinguished from all other matter by the fact that it cannot be created or broken down by ordinary chemical means. Some familiar elements are oxygen, sodium, and iron. Each element's name can be replaced by a one- or two-letter symbol; you will become familiar with some of these during your studies.

As this instruction is heard, the brain processes the information and sends signals through nerves to the muscles to initiate movement.

Answer:

false

Explanation:

Sarin inhibits the enzyme that breaks down acetylcholine, leading to continuous muscle stimulation and thus constant release of calcium ions from the sarcoplasmic reticulum. This can lead to muscle spasms and problems with calcium regulation over time.

Sarin and similar chemicals are known as nerve gases. They function by inhibiting the enzyme acetylcholinesterase, which normally breaks down acetylcholine (ACh) in the synapse. When ACh is not broken down, it continues to stimulate the muscle, causing continual contraction or spasms. In terms of calcium (Ca2+) ions and the functioning of the sarcoplasmic reticulum (SR), sarin would ultimately cause more calcium ions to be released from the SR.

During normal muscle contraction, an action potential triggers the release of calcium ions from the SR. This increase in intracellular calcium concentrations triggers muscle contraction. However, if a sarin-like chemical is present, the continual stimulation of the muscle by unbroken acetylcholine can also trigger constant release of calcium from the SR, overwhelming the normal calcium ion cycling and leading to potential muscle spasms or convulsions.

Furthermore, the sarcoplasmic reticulum cannot effectively store calcium ions for future muscle contractions because the ions are constantly being used. Over a longer period, this could lead to issues with calcium ion regulation and muscle fatigue.

Exposure to sarin or similar chemicals disrupts the normal muscle contraction and relaxation process in a way that it keeps the calcium ion channels open, preventing calcium ions from returning to the sarcoplasmic reticulum, and leading to a persistent contraction of the muscles.

The effect of sarin or sarin-like chemicals on Ca2+ levels in the sarcoplasmic reticulum (SR) can be observed in the change of muscle cell activity otherwise governed by the controlled release and uptake of calcium ions. Normally, an action potential stimulation triggers the release of calcium ions (Ca2+) from the SR. These ions then bind to troponin, which results in muscle contraction. The muscle fibers will continue to shorten and contract as long as Ca2+ ions remain available to bind and ATP is available to drive the process.

When the action potential ends or otherwise stops transmitting its chemical signal, repolarization begins, resulting in the cessation of calcium ion release from the SR. Using ATP-driven pumps, Ca2+ is moved out of the sarcoplasm and back into the SR, causing a drop in calcium levels in the sarcoplasm, and as a result, muscle relaxation.

Exposure to sarin or similar chemicals interferes with this process. These agents can inhibit the repolarization process, thus keeping the calcium ion channels open and preventing the return of Ca2+ back to the SR. This leads to a sustained contraction of the muscles, a condition known as tetany, which can cause severe and often life-threatening disturbances in muscle activity.

the answer is bacteria and archaea

All these options apply except for fossil evidence. This is because according to fossils records tertrapods arose in the Devonian period.

DNA analysis shows that fish are tetrapods’ closest relatives. It has been confirmed by genetic tests that out of the 30,000 types i.e. The closet relative of tetrapods is the lungfish.

Both fish and four-limbed animals are vertebrates.

According to the ‘drying pond’ hypothesis, when water became scarce in the, Devonian, period, tertrapods arose from fishes, and this is based on the fossil record showing more and more tetrapod-like fish before the appearance of tetrapods about 365 million years ago.

Fish and four-limbed animals have very similar embryos. As both fish and human embryos have gill slits.

The evidence supporting the evolution of four-limbed animals from fish includes DNA analysis, a fossil record of transitional forms, similar embryological stages, and the shared vertebrate characteristics. Fossils like Acanthostega and Ichthyostega demonstrate both fish and tetrapod features.

The hypothesis that four-limbed animals, or tetrapods, originated from fish is supported by several lines of evidence:

Key fossil specimens such as Acanthostega and Ichthyostega from the Devonian period show both aquatic and terrestrial adaptations, bridging the gap between fish and later terrestrial vertebrates.
