a. Some of the energy stored in glucose will eventually be transformed into heat.
b. Carbon atoms from glucose could be exhaled by the person as carbon dioxide.
c. Carbon atoms from glucose could later be found in a plant cell.
d. Carbon atoms from glucose could be converted into oxygen during metabolism.

Answers

Answer 1

Answer: a.b.c-true.

              d-false.

a. Some of the energy stored in glucose will eventually be transformed into heat.

This is through  the process of Glycolysis (and Krebs's cycle )where the Carbon atoms in the glucose(substrate level phosphorylation) undergo metabolism with the liberation of ATPs as  heat during  metabolisms. The glucose serves as the substrate for the generation of heat.However,largest amount of ATP's  is expended as heat during oxidative phosphorylation,due to the glucose used as substrate in preceding stages of glycolysis and Kreb Cycle.

b. Carbon atoms from glucose could be exhaled by the person as carbon dioxide.

Yes, this is through glycoylsis and kreb's Cycle where  CO2 is given off as during metabolisms as one compound change from one form to another.E.g from Citric acid(6C) to Succinate(5C),some Carbon atoms are lost as C02. Like during glycolysis.

C. Carbon atoms from glucose could later be found in a plant cell.Yes this is because  the CO2 expired  by human could be trapped by green plants and react with water in the presence of sunlight trapped by chlorophyll to form carbohydrate in plants.This is photosynthesis.

Explanation:

Carbon can't not be converted to oxygen,big FALSE.

Is crick and Watson a type of genetic test

Answers

No, "Crick and Watson" is not a type of genetic test. Crick and Watson refer to James D. Watson and Francis Crick, who were scientists involved in the discovery of the structure of DNA. They proposed the double-helix structure of DNA in 1953, which provided the foundation for understanding genetic information and its role in heredity.

Genetic tests, on the other hand, are laboratory tests that analyze an individual's DNA or genes to provide information about their genetic makeup, potential genetic disorders, or predispositions to certain conditions.

These tests can be used for various purposes, such as diagnosing genetic disorders, predicting the risk of developing certain diseases, determining carrier status for genetic conditions, or providing ancestry and genealogical information.

While Crick and Watson made significant contributions to the field of genetics, they are not directly associated with genetic testing. Genetic tests are based on scientific advancements and technologies developed after their groundbreaking discovery of the DNA structure.

Compare and contrast transcription in bacteria and eukaryotes.

REAL ANSWERS ONLY! NO LINKS!

Answers

According to the research, the correct answer is the enzyme in charge of transcription in bacteria in the synthesis of any RNA is RNA polymerase, unlike eukaryotic cells, in which there are different types of enzymes depending on the type of RNA transcribed .

How is transcription in bacteria and eukaryotes?

Bacteria have a single type of RNA polymerase, which is a complex enzyme made up of several subunits, being responsible for transcription, polymerizes in the 5'-3' direction and does not need primers.

In this sense, transcription in eukaryotes is much more complex than in bacteria, it takes place in the nucleus, transcription is carried out by 3 types of RNA polymerases and it has a more complex regulation, in which numerous transcription factors participate that promote the initiation.

Therefore, we can conclude that in eukaryotes, DNA has to bind to transcription factors and there is a great deal of specialization of RNA polymerases, while in bacteria they have a single type of RNA polymerase.

State 5 effects of exercise with varying intensity on the immune system.

Answers

Varying intensity of exercise can result in different effects on the immune system, such as increased natural killer cell activity, decreased inflammation, improved antibody response, increased white blood cell count, and increased cytokine production.

What are the 5 effects of exercise with varying intensity on the immune system?

Here are 5 effects of exercise with varying intensity on the immune system:

Moderate Intensity Exercise: Regular moderate intensity exercise has been shown to enhance immune function by increasing the circulation of immune cells and antibodies in the body.

High Intensity Exercise: Short-term high-intensity exercise can lead to temporary suppression of the immune system. This is because intense exercise causes stress on the body, leading to the release of stress hormones that can suppress immune function.

Chronic Intense Exercise: Prolonged, intense exercise can lead to a decrease in immune function and increase the risk of infection if the body is not given adequate time to recover.

Resistance Training: Resistance training has been shown to boost immune function by increasing the production of immune cells.

Aerobic Exercise: Aerobic exercise has been shown to boost the immune system by increasing the number of natural killer cells, which are a type of immune cell that helps to fight off infections. Aerobic exercise can also increase the circulation of immune cells and antibodies in the body, improving immune function.

What's the difference between primary succession and secondary succession?​

Answers

Primary succession and secondary succession are two different processes of ecological succession that occur after a disturbance in an ecosystem.

Primary succession is the process by which a new ecosystem is formed on barren land where no soil or organisms exist, such as after a volcanic eruption or glacial retreat.

The process begins with the colonization of bare rock or sand by pioneer species like lichens and mosses. Over time, these organisms break down the rock or sand, creating soil that can support the growth of larger plants like grasses and shrubs. Eventually, trees and other complex organisms take root, creating a mature ecosystem.

Secondary succession, on the other hand, occurs when a disturbance, such as a wildfire or human activity, destroys an existing ecosystem but leaves behind soil and some organisms.

The process begins with the growth of pioneer species that can quickly colonize the area, such as weeds and grasses. As the ecosystem recovers, more complex organisms move in, and the ecosystem slowly returns to its previous state.

In summary, primary succession occurs on bare land without soil or organisms, while secondary succession occurs on land that has been disturbed but still contains some soil and organisms. The processes of succession are essential for the renewal and recovery of ecosystems after a disturbance.

Answers

As the temperature exceeds the optimal range, enzyme activity rapidly decreases due to the denaturation of the enzyme.

What is Temperature?

Temperature has a significant effect on enzyme activity, as enzymes have an optimal temperature range in which they function most efficiently. At temperatures below the optimal range, enzyme activity is reduced due to a lack of energy, resulting in fewer successful collisions between the enzyme and substrate molecules.

Enzyme proteins have a specific tertiary structure that is maintained by various weak chemical bonds and interactions such as hydrogen bonds, hydrophobic interactions, and disulfide bridges. A temperature of 60°C can cause the enzyme protein to denature, as the increased kinetic energy of the molecules causes the weak bonds to break.

Enzyme denaturation is not reversible because it involves the irreversible breaking of the weak chemical bonds and interactions that maintain the protein's three-dimensional structure. Once these bonds and interactions are broken, it is very difficult for the protein to return to its original shape.

This image shows a freshwater stream flowing into an ocean. How does the addition of fresh water affect the salinity of the ocean water?

Answers

The addition of fresh water from a stream reduces the salinity of the ocean water at the point of discharge.

When a freshwater stream flows into the ocean, it brings a lower concentration of salt compared to the seawater. This dilutes the ocean water, reducing its salinity at the point where the freshwater is discharged.

However, the effect on the ocean's overall salinity is usually insignificant as the ocean is a vast body of water with a huge volume and the addition of freshwater is relatively small.

Additionally, the movement of ocean currents disperses the freshwater, reducing the localized effect even further. Nevertheless, significant inputs of freshwater from melting glaciers or heavy rainfall can have a larger impact on the ocean's salinity in the affected regions.
