If the size of an ecosystem decreases because of a hurricane, how are the organisms living in the ecosystem affected?
A. The carrying capacity of the ecosystem increases because there are more resources, decreasing competition among organisms.
B. The carrying capacity of the ecosystem decreases because there are more resources, decreasing competition among organisms.
C. The carrying capacity of the ecosystem decreases because there are fewer resources, increasing competition among organisms.
D. The carrying capacity of the ecosystem increases because there are fewer resources, decreasing competition among organisms.
If the size of an ecosystem decreases because of a hurricane, then the organisms living in the ecosystem are affected since the carrying capacity of the ecosystem decreases because there are fewer resources, increasing competition among organisms (Option C).
What is the carrying capacity of the ecosystem?The carrying capacity of the ecosystem makes reference to the ability to support a given number of organisms and populations in a particular region.

cellulose is not highly branched because it ________.
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.

The polymerase chain reaction can only be used to amplify genes that have already been cloned and sequenced. Why is this true?.
This is True as the primers for the gene must first be obtained in order to abundantly segment a gene using PCR.
Genomic DNA (gDNA), complementary DNA (cDNA), and plasmid DNA are only a few examples of the types of DNA sources that may be used as PCR templates for replication. However, the DNA's structure or complexity influences the ideal input levels for PCR amplification. The sample is heated in order to cause the DNA to denature, or separate into two pieces of single-stranded DNA before the PCR is used to amplify a section of DNA.
Then, using the first two strands of DNA as templates, an enzyme called "Taq polymerase" creates or constructs two new strands of DNA. Instead of amplifying DNA using PCR, this method creates circles by cloning a collection of DNA fragments onto a retroviral vector.

Giant tube worms living near vents on the ocean floor do not have a functioning intestine. Instead they have a modified gut full of bacteria that provide the worms with carbohydrates. What is the energy that the bacteria use to make the carbohydrates?.
The energy that bacteria use to make carbohydrates by consuming small bacteria that, through a process known as chemosynthesis, obtain all of their energy from the substances in the water, because of the dark hue of the material that these hydrothermal vents emit, they are also referred to as "black smokers."
Prior to the discovery of odd hydrothermal vents by scientists examining the deep Pacific Ocean floor, the enormous tube worm, also known as Riftia pachyptila, was completely unknown to science. These vents circulate water that seeps down through fractures or faults in the rock and is heated by volcanic activity. The water that comes out of the vent is incredibly chemical and mineral-rich. Scientists were startled to see entire ecosystems of species surviving near these vents because this deadly soup of chemicals would be fatal to the majority of animals.
These critters were prospering in total darkness despite the water's temperature being close to boiling. Because they do not rely on sunlight for energy, the species that dwell close to these vents are distinct from all other living beings on earth. Instead, the several smaller species of tube worms that live in shallower waters are closely linked to the big tube worms.

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.

what makes agglutination by antibodies possible?
Answer:
The presence of agglutinins is what makes agglutination by antibodies possible.
Explanation:
The unique binding characteristics of antibodies and their ability to cross-link antigens enable agglutination by antibodies.
The immune system reacts to the presence of foreign substances known as antigens by producing Y-shaped proteins called antibodies. Agglutination occurs when antibodies recognize and bind to multiple antigens present on the surface of cells or particles. Because each antibody molecule has two antigen-binding sites, it can bind to two different antigens at once. This binding leads to the deposition or aggregation of cells or particles, which form cross-links between the antigens.

During adaptation to lower temperatures, an organism may increase its production of lipids with less saturated acyl chains.
a. True
b. False
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.

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?.
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.
