Enzymes tend to denature at high temperatures thus they cannot operate under a wide range of temperature and work efficiently at optimum temperature. Option (b)
Enzymes are proteins that function as biological catalysts, speeding up chemical processes. Substrates are molecules on which enzymes can function, and the enzyme changes the substrates into various molecules known as products. Almost all metabolic activities in the cell require enzyme catalysis to occur at fast enough rates to support life. Enzymes catalyze individual stages in metabolic processes.
Enzymology is the study of enzymes, and pseudoenzyme analysis acknowledges that certain enzymes have lost their capacity to carry out biological catalysis over evolution, which is often reflected in their amino acid sequences and strange 'pseudocatalytic' features.

When students are working in the lab, they have the option to view prepared slides or to make their own. There are two common slides that students make: a dry slide and a wet slide.
Dry slide: On a slide, either with or without a coverslip, a specimen is placed. wet slide: On the slide, a specimen is placed on a drop of water and covered with a coverslip.
To produce a viewable image of microscopic organisms and samples, a microscope is required. When looking at transparent objects that can fit on a microscope slide, the compound light microscope is often used. A thin, rectangular glass plate that can hold a variety of microscopic specimens is called a microscope slide. Depending on the kind of specimen you're looking at, you can prepare a microscope slide in a number of different ways. Just like its name suggests, a dry mount is A cover slip placed over the item you intend to observe on the slide. Water is not required. When a sample is placed on a wet-mount slide with a drop of water and covered by a coverslip, surface tension holds it in place.

explain why the templating region of the rna includes one and a half repeats of the telomeric sequence
A primer for the trailing strand is created when the leading strand doubles back on itself. The typical start of RNA and polymerase activity can produce the lagging strand.
The DNA ends of linear chromosomes, known as telomeres, are made up of tandem repeats of basic DNA sequences. DNA polymerases are unable to duplicate the 5' ends of linear DNA molecules because they can only stretch primers in a 5' to 3' direction. The telomeres must be replicated using a reverse transcriptase known as telomerase. As a component of the enzyme complex, this telomerase carries its own RNA template that is complementary to the repetitive sequences in the telomeres. The free end of the telomeric DNA links to the telomerase's ARN, which later serves as a template for the extension of the conductor strand of the template in yet another unity of repetition. A typical beginning of DNA synthesis can be used to create the lagging strand.

What is a breakwater used for?
A breakwater is an offshore shore-parallel structure that "breaks" waves to lessen the force of the waves that reach the beach and to promote sediment accretion between the beach and the breakwater.
What are the advantages of a breakwater?By soaking up wave energy during storm events, living breakwaters lessen the consequences of storm surge and coastal erosion. As waves crash against the structure, their energy is diminished, calming waters on the breakwater's shoreward side and lowering the direct impacts on the shoreline.

where does the energy come from that drives water transport in plants?
The energy that drives water transport in plants comes from the process of photosynthesis.
Plants use the energy from sunlight to transform carbon dioxide and water into glucose (sugar) and oxygen during the process of photosynthesis. The oxygen is discharged into the atmosphere while the glucose serves as a building block and energy source for the plant.
Water flows from the roots to the leaves and evaporates from their surfaces during the process of water transport in plants, commonly known as transpiration. The transpiration pull, a process that results in a suction pressure that draws water from the roots upward, is caused by this. The glucose created by photosynthesis serves as a source of energy for this activity. Thus, photosynthesis serves as an indirect source of energy for plants' requirement to move water.

Girls' legs are longer than boys' in relation to the rest of the body.
Boys start to add fat on their arms, legs, and trunk.
The statement "Girls' legs are longer in relation to the rest of the body than boys'" is true.
During adolescence, girls typically go through a period of growth spurt, during which they experience a rapid increase in height. This growth spurt is often accompanied by changes in body proportions, with the legs becoming relatively longer compared to the rest of the body. This difference in body proportions between boys and girls is a normal aspect of human growth and development and is due to a combination of genetic and hormonal factors. However, it is important to note that these differences are averages and there is significant variability within each gender.

How do the lungs and kidneys, respectively, compensate for metabolic acidosis?
Lungs and kidneys, respectively, Option C: Hyperventilation; excrete hydrogen ions in order to compensate for metabolic acidosis.
Since the majority of the acid in the body is carbonic acid, which is created from carbon dioxide during metabolic activities, the lungs do this by exhaling carbon dioxide. The rate at which you breathe determines how much carbon dioxide is expelled. This is termed as hyperventilation in lungs. When the kidneys are not eliminating enough acid from the body or when the body produces too much acid, metabolic acidosis develops. Thus, option C is the appropriate choice.
If left untreated, metabolic acidosis can progress to acidemia, which is characterized by low blood pH (below than 7.35) as a result of either increased body production of hydrogen ions or the body's inability to produce bicarbonate ([tex]HCO^{3}[/tex]) in the kidney.
