Does sustainability cause environmental pollution in plants
Answer:Environmental pollution is any discharge of material or energy into water, land, or air that causes or may cause acute (short-term) or chronic (long-term) detriment to the Earth's ecological balance or that lowers the quality of life. Pollutants may cause primary damage, with direct identifiable impact on the environment, or secondary damage in the form of minor perturbations in the delicate balance of the biological food web that are detectable only over long time periods.
Air pollution is the process which the substances and the energy forms are not present in normal atmospheric composition reach the atmosphere, or are present but in much lower concentrations.Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or cause damage to the natural environment or built environment, into the atmosphere.
More than 3,000 substances that are not part of the atmospheric composition, falling in the atmosphere can be considered air pollutants.
Some substances that are normally present in the atmosphere in a certain concentration can be considerate pollutants because their concentration is much higher than usual concentration.
Also certain substances that are normally present in certain layers of the atmosphere (e.g. ozone in the stratosphere), once arrived in the troposphere is pollutant.
Some gases, such as oxides of nitrogen may have beneficial effect on vegetation, after hydration may affect the leaf fertilizer.
The air pollutants factors can be chemical (chemicals), mechanics (particles in suspension) physical (ionizing radiation) and acoustic (noise).

Explanation:
The DNA or deoxyribonucleic acid also referred to as Double-Helix is found in the nucleus of the cell. It holds the genetic code passed from parents to offsprings during reproduction. DNA strands and proteins form a complex in the nucleus. The DNA polymerase as well as ligase and helicase help in the replication and repair of DNA strands.
The RNA is complementary to its DNA counterpart. It is synthesized from the DNA by the RNA polymerase during the process of transcription. A sequence of three DNA or RNA is called a condon, and each condon is an Amino acid or stop bit. The RNA has a single-helix shape
Central Dogma is crucial for the transfer of genetic information as well as for the proper functioning of the organisms. Central Dogma mainly comprises Replication, Transcription and Translation.
Replication is a process in which the DNA makes a copy of itself with the help of enzymes DNA polymerase, ligase, helicase and many more.The replicated DNA undergoes transcription in which DNA gets transcribed into mRNA with the help of RNA polymerases and many other factors. The transcribed mRNA then forms amino acids and the amino acids produce codons and protein which is essential for cell structure and functioning.

Calvin cycle:
In Calvin cycle number of carbon atoms are constant in CO₂ and used to construct three-carbon sugars. This manner is fueled by, and established on, ATP and NADPH from the mild reactions.The Calvin cycle reactions occurs in three main stages: carbon fixation, reduction, and regeneration of the starting molecule.So, in the question it is asked how many G3P would be produced if there are 36 carbon dioxide that enters the Calvin cycle. Thus the answer is 12
In order for one G3P to go out the cycle (and move in the direction of glucose synthesis), 3 CO₂ molecules need to input the cycle, imparting 3 new atoms of constant carbon.

In marsupials, X inactivation occurs exclusively to paternally derived chromosomes. Which genes will
ALWAYS be expressed in this situation?
A. maternal X-linked genes
B. paternal X-linked genes
C. maternal Y-linked genes
D. paternal Y-linked genes
Answer:A maternal x linked genes
Explanation:
In marsupials, X inactivation occurs exclusively to the paternally derived chromosome. The genes which are always expressed in this situation is that of maternal X linked genes (option A).
The gene that will be expressed in the situation is maternal X-linked genes. The correct option is A.
What is maternal gene?Maternal genes are those whose RNA or protein products are produced or deposited in the oocyte or are present in the fertilized egg or embryo before zygotic gene expression begins.
The phenotype of the offspring is determined by the maternal genotype. Maternal effects are frequently observed because the mother provides a specific mRNA or protein to the oocyte, and thus the maternal genome determines whether the molecule is functional.
X inactivation occurs only on the paternally derived chromosome in marsupials. Maternal X linked genes are the only ones that are always expressed in this situation.
Thus, the correct option is A.

How many CO2 molecules are produced when three glucose molecules undergo cellular respiration? Explan
Answer:
18 molecules of [tex]CO_{2}[/tex]
Explanation:
In heterotrophic nutrition, organisms ingest or absorb food made by autotrophs to obtain energy. Planta and other photosynthesizing organisms make sugars via photosynthesis, in a form of (partly) light-dependent biosynthesis.
In mitochondria, they break down sugars through aerobic respiration. For the sugar glucose, this results in the production of carbon dioxide and water along with energy in the form of ATP or adenosine triphosphate.
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
For 3 molecules of glucose, multiply the number of reactants and products...
(C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP ) x 3
Thus...
3 C6H12O6+ 18 O2 → 18 CO2 + 18 H2O + ≅114 ATP
Which two substances are produced during photosynthesis?
Answer:

What two factors cause natural gas to form?
What happens to the particles of a liquid when energy is removed from them?
Answer:
When liquids boil the particles must have sufficient energy to break away from the liquid and to diffuse through the surrounding air particles. As these particles cool down and lose energy they will condense and turn back to liquid.
When energy is removed from the particles of liquid. They become condensed and convert into liquid from vapor.
What is liquid?The liquid is one of the states of matter. It can be identified as it takes the shape of the container in which it is poured. The particles of a liquid are farther from each other than the particles of gas.
The particles of liquid contain energy when they are heated or boiled. The particle gets energy and turns into vapor particles. When the heat is removed and the particle cools down, it again becomes liquid.
More kinetic energy causes particles to travel more quickly and widely apart. Less energetic particles move more slowly and maintain their proximity.
Thus, when liquid molecule particles lose their energy. They go from vapor to liquid as a result of condensation.

If warmer oceans soak up less CO2, what effect do you think rising ocean temperatures will have on the amount of CO2 in the atmosphere ?
Answer:
Warmer water cannot hold as much carbon dioxide, so the ocean’s carbon capacity is decreasing as it warms. In watching for effects of increasing atmospheric carbon on the ocean’s uptake, many people have looked for indications that the carbon content of the ocean is rising faster than that of the atmosphere.
Explanation:
If warmer oceans soak up less CO2, rising ocean temperatures will lead to more CO2 in the atmosphere.
CO2 is being released into the atmosphere both from natural and anthropogenic sources. The natural sources include volcanic eruption, cellular respiration, etc. while anthropogenic sources include all human actions that lead to CO2 emission such as the burning of fossil fuels, agricultural burnings, deforestation, etc.
As net amounts of CO2 is being released into the atmosphere and warmer oceans soak up less CO2, the atmospheric concentration of CO2 will keep increasing.

A student claimed that the following two proteins are the same protein because they contain the same amino acids: (1) Pro-Arg-Lys-Iso-Gly and (2) Pro-Arg-Lys-Gly-Iso. Do you agree or disagree with the student?
Answer:
Disagree
Explanation:
Proteins are made up of chains of amino acids, these fold up and join up with other polypeptides to form the final structure of the protein.
The amino acids are in a different order (Iso and Gly are swapped around). This means the polypeptide chain is different, meaning the final structure and likely the function of the protein will be different.
Therefore, the proteins are certainly not the same protein.
