The carbon emission can be reduced and natural diversity can be preserved by constructing homes as “green buildings”.
A "green building” is one that minimizes or eliminates negative effects on our climate and natural environment all through design, construction, or operation and can create a positive impact. Green buildings protect valuable natural resources and raise our standard of living.
The carbon footprint is the total amount of greenhouse gases including carbon dioxide that is generated by human activity.
Following improvements in house designs can help in reducing the emission of carbon dioxide:
Use of renewable energy resources like solar energy, hydraulic energy, etc because these forms of energy do not emit any greenhouse gases while their production and operation.
Planting indoor plants and creating a garden to absorb the carbon dioxide produced in the house and improve the quality of air.
Installing appliances with more energy stars, these types of appliances have low CFC emissions and hence decrease carbon dioxide trapping in the environment.
Planting a garden with no usage of chemical fertilizers or pesticides to preserve natural diversity.

Gene expression can be regulated differently along the central dogma. Which regulation type would have the fastest effect
Post-translation modification regulation type would have the fastest effect.
Gene expression can be defined as a process in which the information stored in genes in the form of nucleotides gets translated into proteins. This whole gene expression process takes place in multiple steps which are combined as central dogma where the process of formation of new DNA (deoxyribonucleic acid) from pre-existing DNA molecules is termed Replication, the process of transcribing this DNA into mRNA is termed Transcription and the process of translating these mRNA into functional proteins is known as translation.
Post-translation modifications (PTM) as their name suggests are the modifications to the newly synthesized proteins that occur after the completion of the translation process. Phosphorylation, acetylation, hydroxylation, and methylation are some of the commonly known PTMs.

During an action potential, activation of voltage-gated sodium and potassium channels occurs at different rates. What is the effect of this difference on ion flow across an axon membrane?.
K+ departs the cell after Na+, which enters the cell first. Ions can move freely across the axon membrane because of the difference during the action potential.
Because sodium contains a positive charge, the neuron becomes more positive and depolarized. Potassium channels take longer to open. As soon as the cell does open, K+ rushes out, reversing the depolarization.Sodium channels close during the peak of the action potential when potassium leaves the cell. When potassium ions are effluxed, the membrane potential is lowered or the cell becomes hyperpolarized.Because it depends on adenosine triphosphate (ATP) for power, the sodium/potassium pump is sometimes referred to as an ATPase. Outside of the cell, the concentration of Na+ is greater than inside the cell. while the concentration of K+ is is greater inside the cell than outside.learn more about action potential here: https://brainly.com/question/6705448

How are proteins built using the information provided by a molecule of RNA?
Answer:
Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. They also bind tRNAs and various accessory molecules necessary for protein synthesis.
Explanation:
Fatty acids, in particular, essential fatty acids alpha-linolenic and linoleic acid are intimately related to managing inflammation in the body.
Answer:
A cell's messenger RNA molecules contain instructions that are read by the ribosome, which then uses these mRNAs to assemble amino acids into proteins in the precise order specified by the mRNA.
⇒ How are proteins formed?
In essence, proteins are very long sequences of chemicals known as amino acids. A protein's specific amino acid arrangement defines the form it will take, which in turn affects what it will accomplish. For instance, certain proteins have the ideal structure to grasp two more molecules and smush them together in order to combine them (these proteins are called enzymes). Other proteins have the ideal structure to transport significant substances (like hemoglobin, which is a protein that carries oxygen around your blood). Your DNA is also a long chain of molecules, but these molecules are called nucleotides. There are four main nucleotides that make up the chain, and each is represented by a letter (A, C, T, and G). The sequence of "letters" in DNA contains all the information to make proteins in your body. Scientists represent DNA by writing out the sequence of "letters," like ATCTGCCATCCCGT. Now here's the important bit: these letters are arranged in 3-letter words that "mean" an amino acid. For example, "ATC" in DNA corresponds with an amino acid called glutamine. A long chain of these three letter words will match perfectly the chain of amino acids in a protein. So if a protein has amino acids 1, 2, and 3, the DNA corresponding to that protein will have the 3-letter words that mean amino acids 1, 2, and 3 in order. A sequence of DNA that matches a protein is called a gene. When it's time to make a protein, your body unravels the DNA and makes a copy of the gene on a different, very similar molecule called messenger RNA (mRNA). This copying is called transcription--like you're transcribing your notes from your notebook to your computer. This mRNA flies out to a thing in your cells called a ribosome, which actually goes through and READS the RNA sequence and attaches amino acids in the right order. So it will go "okay, these 3 letters mean this amino acid, the next 3 letters mean this amino acid, etc." and just attach all the amino acids in a row.* So you end up with a long long chain (hundreds, even thousands!) of amino acids in the exact sequence of the DNA letters that you had originally. This process of matching DNA "words" to amino acids is called translation--like you're translating from the "language" of DNA to the "language" of proteins/amino acids. This long chain of amino acids then detaches itself from the ribosome, folds itself up, and voila! You have a protein! This is happening millions of times constantly all around your body as all your cells make all the proteins they need to function. Now in reality, it's actually a lot more complicated than that--the DNA isn't always in the right order, the protein can get "cut" and shaped by other things after it detaches, etc. But this is the basic process and is what you need to know!
⇒ How does DNA/RNA store information?
Adenine, guanine, cytosine, and thymine/uracil are the four bases that make up the quaternary code, which is the sort of coding used by DNA and RNA to store information. Ribonucleic acid (more particularly, messenger RNA) is introduced when a cell needs to code for a protein. Temporarily attaching to the DNA bases, the mRNA bases duplicate the DNA's instructions. The mRNA next exits the nucleus and enters the ribosomes. Then transfer RNA, or tRNA, enters the picture. It has a three-base region (a codon) that binds to the mRNA and an amino acid linked to the end. The amino acid is then released once the tRNA attaches to the mRNA. After that, it joins a protein or polypeptide chain.

Frozen red blood cells that have been thawed, deglycerolized and reconstituted in an open system must be used within 24 hours.
The classical way of preserving the blood cells is to store them at low temperatures. The phenomenon by which the red blood cells are frozen and defrosted is called cryopreservation. This process requires the use of glycerol to safeguard the RBCs from damage. The glycerol is washed off prior to transfusion to avoid hemolysis. After removal of glycerol, the shelf life of RBCs in case of an open system is only for 24 hours. This creates the need of immediate use of the frozen RBCs.

What is the RPR test?Rapid Plasma Regain, or RPR, is a syphilis screening test. It evaluates the presence of molecules (proteins) known as antibodies in the blood of individuals who may have the disease. It is frequently used to test pregnant women for the condition and is used to check people who exhibit signs of STDs. The effectiveness of syphilis therapy is also evaluated using the test. Antibody levels for syphilis should decrease following antibiotic therapy. Another RPR test can be used to keep track of these values. Levels that stay the same or increase may indicate an ongoing infection. Infectious mononucleosis: The Epstein-Barr virus is the common infectious agent that causes infectious mononucleosis (EBV). The term "glandular fever" is used more frequently. Young adults between the ages of 15 and 25 are most commonly affected by infectious mononucleosis.

What are convective cells?At a global level, it occurs unequal warming of the atmosphere, which depends on many factors and varies with latitude. This effect occurs because solar radiation reaches the earth differently at different latitudes.
Unequal warming of the atmosphere results in convective circulation cells: Hardley cell, Ferrel cell, and Polar cell.
The term convective cell refers to air getting warm, expanding, and ascending. As it gets to higher altitudes, it gets colder and thicker, and hence descends again.
In each hemisphere,
Warm air ascends at the equator and approximately at 60º latitude. Cold air descends at approximately 30º latitude and at the poles.These air masses' circulation generates superficial winds that blow toward the equator between 0º-30º latitude and toward the poles between 30º-60º latitude.
Hardley cell ⇒ It occurs between 0º and 30º latitude (north and south).While the tropical air gets warmer, it ascends and produces a low atmospheric pressure area over the equator.
The dense air coming from the north and south moves to a low-pressure area and forms the superficial winds that blow toward the equator.
As the warmed air ascends, it is pushed by new masses of warm air that are also rising. The equator turns to be the divergence point where warm masses of air rise and get separated as they get colder and pushed to the different poles.
When the air gets cold enough, it descends again at approximately 30º latitude (north and south). This is the horse's latitude. And the cycle starts all over again.
The Ferrel cell ⇒ It occurs between 30º and 60º latitude The polar cell ⇒ occurs between 60º and the poles.High-pressure zones send cold winds from the poles to lower latitudes toward the equator.
As these winds go to lower latitudes they get warmed, and they start accumulating humidity.
Approximately at 60 degrees latitude, they meet with warm winds coming from the horses' latitude (30 degrees latitude). They both ascend while getting cooled. They cannot maintain humidity, so it precipitates.
Then winds move back to the poles, where they get cold again, so the cycle continues.
In conclusion,
0º and 60º latitude ⇒ low pressure30º and 90º latitude ⇒ high pressureThe correct option is C.
Low pressure areas at the equator result in high rainfall and produce Africa's rainforests.
High pressure areas occur at 30 degrees north and south, resulting in very little rain and produce Africa's deserts.
