During adaptation to lower temperatures, an organism may increase its production of lipids with less saturated acyl chains.
a. True
b. False
Answers
It is wrong, because lipids are formed with more saturated acyl chains. During adaptation to low temperatures, organisms may increase the production of lipids with more saturated acyl chains. So it's false.
As temperature decreases, the composition of membrane lipids (phospholipid fatty acids) is expected to become more unsaturated to maintain homeostasis. Although they differ in function, storage lipids (triacylglycerol fatty acids) are expected to respond to temperature changes in a similar manner.
When saturated fatty acids are compressed by a drop in temperature, they are compressed together to form a dense and fairly hard membrane. When unsaturated fatty acids are compressed, their terminal 'kinks' displace adjacent phospholipid molecules, maintaining membrane fluidity.

Not even all viruses have an envelope-like membrane surrounding the capsid. Viruses do have a wall outside of the capsid, but it originates from the host.
What do viruses possess?
A virus's outer layer is formed of a nutrient coat that serves as the nucleus of its mitochondrial Genome, either RNA or Genetic material. The second spikey coat of the mailbox is occasionally seen around the virus. Viruses are able to attach to and enter new hosts.
How do viruses become made?
It's probable that mobile genetic elements that had the ability to move between cells gave rise to viruses. They might be related to organisms that were once free-living but later switched to a parasitic mode of reproduction. It's possible that viruses existed before cellular life developed and helped to shape it.

cellulose is not highly branched because it ________.
Answers
Cellulose is not highly branched because it does not have alpha(1-->6) linkages.
Long chains of monosaccharides connected by glycosidic linkages are known as polysaccharides. Glucose makes up starch, glycogen, and cellulose, three significant polysaccharides. In plants and animals, respectively, starch and glycogen serve as temporary energy reserves. Glycosidic linkages bind together the glucose monomers.
A linear polymer glucan, cellulose is made up of over 100,000 glucose units connected by -beta (1-4)-glycosidic bonds. The cellulose chain's regular arrangement of hydroxyl groups causes the formation of H-bridges, which results in a fibrillar structure with crystalline properties.
Hydrogen bonds are used to bind the parallel-arranged cellulose molecules together. When combined with other cellulose molecules, these long, cable-like structures create the robust support structure.

What term is given to the projections of gray matter toward the outer surface of the spinal cord?.
Answers
The gray matter in the spinal cord is shaped like a butterfly. The dorsal process is called the dorsal horn and the ventral process is called the ventral horn.
What is a dorsal horn?The dorsal horn of the spinal cord contains the first relays for afferent input from the skin, muscles, and internal organs of the body. The superficial dorsal horn contains at least some neurons that maintain selectivity for modalities encoded by primary afferent terminals. The intermediate processing center for this information is the dorsal horn, which consists of a complex network of excitatory, inhibitory, and projection neurons that transmit processed somatosensory information from the spinal cord to the brain.
At the back of the spinal cord, the central gray matter forms her two arms, each known as the dorsal horn. The dorsal horn consists of the cell bodies of sensory neurons. The front two arms of the spinal cord, located in the central gray matter, are called the anterior horns.

Coral reefs look like they are made of rocks. They are actually made of animals. The animals are tiny.
Answers
Coral reefs are huge underwater structures composed of the skeletons of colonial marine invertebrates called coral.
The coral species that constructed reefs are known as hermatypic, or "hard," corals because they draw out calcium carbonate from seawater to produce a hard, durable exoskeleton that safeguards their soft, sac-like body.
Other species of corals that are not intricated in reef-building are known as soft corals. These types of corals are pliable organisms often similar to plants and trees and comprise species such as sea fans and sea whips.
Each coral is referred to as a polyp. Coral polyps thrive on the calcium carbonate exoskeletons of their ancestors, putting their exoskeleton to the existing structure.

During photosynthesis, the energy used to pump protons comes from ___________, whereas in cellular respiration it comes from _____________.
Answers
During photosynthesis, the energy used to pump protons comes from ______light_____, whereas in cellular respiration it comes from ______NADH/FADH₂_______.
What are the steps in photosynthesis?The first step in photosynthesis is the absorption of light by chlorophyll bound to chloroplast thylakoid proteins. The absorbed light energy is used to remove electrons from electron donors such as water to form oxygen.The electrons are then transferred to the primary electron acceptor, quinine (Q.). Electrons are further transferred from the primary electron acceptor to the final electron acceptor (usually NADP⁺).Proton transfer from the thylakoid lumen to the stroma via the F₀F₁ complex generates ATP from ADP and Pi.The NADP and ATP produced in steps 2 and 3 provide the energy, and the electrons power the process of reducing the carbon to a six-carbon sugar molecule.The first three steps of photosynthesis, are directly dependent on light energy and are thus, called light reactions, while the reactions in the last step are independent of light and thus are termed dark reactions.

2 liters of 2% sucrose solution from 10% concentrated stock solution
Answers
In order to get 2 liters of 2% sucrose solution from 10% concentrated solution, 0.4 liters of the stock would be taken and diluted with 1.6 liters of water.
DilutionThe problem here is that of a simple dilution. The dilution principle affirms that the number of moles before and after dilution must be constant.
[tex]m_1v_1[/tex] = [tex]m_2v_2[/tex]
where:
[tex]m_1[/tex] = initial concentration or concentration of the stock solution.
[tex]m_2[/tex] = final concentration or concentration of the diluted solution.
[tex]v_1[/tex] = initial volume or volume of the stock solution to be diluted.
[tex]v_2[/tex] = final volume or volume of the diluted solution
In this case:
[tex]m_1[/tex] = 10%
[tex]m_2[/tex] = 2%
[tex]v_2[/tex] = 2 liters
[tex]v_1[/tex] = [tex]m_2v_2/m_1[/tex]
= 2 x 2/10
= 0.4 liters
Thus, 0.4 liters of the 10% stock solution would be taken and diluted up to the 2 liters mark (by adding 1.6 liters of water) to make a 2% solution.

Answers
In bacteria, a partially diploid strain may result from acquiring an F' factor and specialized transduction.
Specialized transduction and the acquisition of an F' factor lead to the emergence of a partly diploid strain in bacteria. Due to this, some of the bacteria's genetic components can exist in duplication (2 copies) (Chromosomes). One of those copies can be discovered on the bacteria's chromosome, while the other copy can be found in its plasmid.
Merodiploids are bacteria that have been found to have the partial diploid strain.
A genetic mechanism called specialized transduction allows genes to be transferred between bacteria. The F factor is also a plasmid that encourages bacteria to conjugate with one another and exchange genetic material.

You are studying a drug that blocks translation in bacteria. You want to know more about its mechanism of action. You treat bacteria with the drug and isolate mrnas with their associated proteins from the treated bacteria. In bacteria treated with the drug, you find that small ribosomal subunits are bound to the mrnas, but not the large subunits. In which stage does this drug arrest translation?.
Answers
According to the study, the drug arrest translation of proteins in the initiation stage. Thus, the correct option is A.
What is Translation?Translation is the process of formation of proteins from the mRNA which is synthesized by the DNA in the nucleus of cell. Here, the drug which blocks translation in bacteria and the small ribosomal subunit (30S) binds to the mRNA but not the large ribosomal subunit (50S). So we can say that large ribosomal subunit binds to mRNA after the formation of the 30S initial complex. However, if it was treated with the drugs such as (clindamycin, macrolides, etc) in the translation process then this drug bind to the large ribosomal subunit (50S) and blocks the peptide bond formation between the amino acid and thus stop the initiation step of the translation.
So, we can say that if we use the drug in the bacterial translation process then the drug bind to the large ribosomal subunit and stop the initiation step of the translation.
Therefore, the correct option is A.

Why does a shaved camel standing in the sun require more water than an unshorn camel?.
Answers
In order to lower the bog, sweat essentially cools the air around the body as it evaporates. The shaved camel needs more water because it dries out more quickly than an onshore camel.
What justifies the process of evaporation?The process of evaporation causes a liquid to become a gas. The phenomenon is easy to visualize when raindrops "vanish" on a hot day and when wet clothing dry in the sun. In these situations, the liquid water isn't truly dissipating; instead, it's evaporating into such a gas known as the water vapor. We experience global evaporation.
