How is DNA expression regulated in individual cells?

Answers

Answer 1

Answer:

Gene regulation can occur at any point during gene expression, but most commonly occurs at the level of transcription (when the information in a gene's DNA is transferred to mRNA). Signals from the environment or from other cells activate proteins called transcription factors.

Explanation:

Answer 2

Gene regulation can take place at any stage of gene expression, although it often happens during transcription when the data from a gene's DNA is converted to mRNA.

What is gene regulation?

Proteins known as transcription factors are activated by signals from the environment or from other cells.

Limiting the amount of mRNA that is generated from a certain gene regulates transcription.

Eukaryotic gene expression is regulated by the nucleus-based mechanisms of transcription and RNA processing and the cytoplasm-based activities of protein translation.

Therefore, the translation of mRNA into proteins is regulated by post-transcriptional processes, which constitute the second level of regulation.

1. Describe how photosynthesis and chemosynthesis differ in terms of how energy is converted,

Answers

Answer:

1) Photosynthesis:

Reactants- 6CO2 (carbon source), 6H2O, light energy

Products- C6H12O6 (organic molecule), 6O2

2) Chemosynthesis:

Reactants- 6CO2 (inorganic carbon source), 6H2O, 3H2S ( chemical energy source)

Products- C6H12O6 (organic molecule), 3H2SO4

Please find the difference in terms of how chemosynthesis and photosynthesis convert energy below

Explanation:

Photosynthesis and Chemosynthesis are both autotrophic forms of nutrition. They differ in the form of energy and reactants' used to power their respective processes.

- Photosynthesis is the process whereby plants synthesize their food (glucose) from carbon dioxide (CO2) and water (H20) in the presence of sunlight as energy, releasing oxygen gas (O2) as a product.

6CO2 + 6H2O -> C6H12O6 + 6O2

- Chemosynthesis, on the other hand, is the process whereby certain bacteria and fungi that lacks access to light synthesize organic food (glucose) from an inorganic carbon soure (carbon dioxide, CO2), water (H2O), and hydrogen sulfide (H2S), used as chemical energy source, releasing sulfates (H2SO4) as a product

6CO2 + 6H2O + 3H2S -> C6H12O6 + 3H2SO4

However, photosynthesis converts solar energy (energy in sunlight) to chemical energy (in glucose) while chemosynthesis converts inorganic chemical energy to organic chemical energy.

The chemical reaction(reactant and product) for photosynthesis and chemosynthesis are  as follows:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

18H₂S + 6CO₂ + 3O₂ → C₆H₁₂O₆ (carbohydrate) + 12H₂O + 18S

Photosynthesis reaction:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

This reaction is a reaction between carbon dioxide and water to form sugar and Oxygen in the presence of sunlight.

The chemical equation of photosynthesis can be interpreted as 6 molecules of  carbon dioxide reacting with 6 molecules of water to form a simple sugar and 6 oxygen molecules in the presence of sunlight . The names of the reactant and products are as follows:

carbon dioxide + water → Sugar + oxygen

Chemosynthesis reaction:

Chemosynthesis is the conversion of carbon compounds and other molecules into organic compounds.

Using H₂S as an energy source a chemosynthetic reaction can be represented below:

18H₂S + 6CO₂ + 3O₂ → C₆H₁₂O₆ (carbohydrate) + 12H₂O + 18S

From the reaction Hydrogen sulphide was used as a source of energy and it reacts with carbon dioxide and oxygen to produce sugar, water and sulphur.

Hydrogen sulphide + carbondioxide + oxygen →  Sugar + water + sulphur.

Glucose reaches each and every cell through the circulation of ____ .

Answers

Answer:Blood

Explanation:

Glucose reaches each and every cell through the circulation of blood, which is present in Option A as the primary function of the circulatory system, which includes the heart, blood vessels, and blood, is to transport essential nutrients.

What is blood?

After food is digested and absorbed into the bloodstream, glucose is transported to cells throughout the body by the circulatory system, which consists of the blood, heart, capillaries, etc., where the heart pumps blood throughout the body via arteries, which branch into smaller vessels called arterioles and then into even smaller capillaries. The circulatory system also plays an important role in removing waste products, including carbon dioxide, from the body's tissues, so glucose has been used by cells for energy, the waste product, carbon dioxide, is transported back to the lungs, where it is exhaled.

what is an abiotic factor and a biotic factor? ​

Answers

Answer:

Explanation:

The biotic factor or biotic component is the living organism that shapes an ecosystem. Abiotic factors or abiotic components of an ecosystem are the non-living physical and chemical composition of nature. The abiotic factors will define which organisms are able or not to live in a specified place. The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment. So, the abiotic factors are controling the biotic factors of an environment. The biotic factors refer to all the living beings present in an ecosystem, and the abiotic factors refer to all the non-living components like physical conditions (temperature, pH, humidity, salinity, sunlight, etc.) ... Therefore, both the abiotic and biotic resources affect survival and reproduction process.

In biology, abiotic factors can include water, light, radiation, temperature, humidity, atmosphere, acidity, and soil.

Biotic factors include animals, plants, fungi, bacteria, and protists. Some examples of abiotic factors are water, soil, air, sunlight, temperature, and minerals.

Why can water have no net charge but have slight
charges in different parts of the molecule?

Answers

Water molecule is made up of one atom of oxygen and two atoms of hydrogen. The water is a polar compound and has slight charges due to differences in the charges.

Water molecule is composed of hydrogen and oxygen and is inorganic transparent liquid. The hydrogen and oxygen in a water molecule are linked by covalent bonds.

The oxygen is electronegative and attracts electrons. There is however no overall charge on the water molecule, but atoms of the compound have slight charges.

The unequal sharing of electrons between hydrogen and oxygen can give them slight positive and negative charges, respectively.

Thus, there are slight charges present on oxygen and hydrogen.

Answers

Answer:

B.They will break down.

Explanation:

Entropy is defined as the thermal energy per unit temperature that contribute to doing useful work in a system. The concept of entropy says that entropy is measured by the random or disordered motion of molecules of a system.

As the entropy will increase over time, the molecules will break down into two or more due to the random and disordered motion of molecules.

Hence, the correct answer is "B.They will break down.".
