all of the following cell components are found in prokaryotic cells except

Answers

Answer 1

The correct option is (D) because the purpose of the endoplasmic reticulum is to manufacture proteins and the proteins are synthesized in prokaryotic by ribosomes that are free within the cell's cytoplasm.

Single-celled microbes known as prokaryotic cells are estimated to be the oldest on the planet. Bacteria and Archaea are examples of prokaryotes. Cyanobacteria are photosynthetic prokaryotes that perform photosynthesis. Because a prokaryotic cell has a single membrane, all processes take place within the cytoplasm. They can be either free-living or parasitic. The following is the structure of a prokaryotic cell: In addition to the cell wall, capsules are an outer protective layer found in bacterial cells. It aids in moisture retention, cell protection when engulfed, and cell adhesion to nutrients and surfaces. Cell Wall is the cell's outermost layer that gives the cell form and the cytoplasm is a gel-like component and cell component that is mostly constituted of enzymes, salts, and cell organelles. Ribosomes are tiny particles found in bacterial cells. They are composed of ribosomal protein and act as a protein production site. Certain organelles, such as mitochondria, endoplasmic reticulum, and Golgi bodies, are absent in prokaryotic cells.

competitive inhibition vs noncompetitive inhibition

Answers

Competitive inhibitors compete for the binding site in protein with the actual ligand, whereas non-competitive inhibitors do not.

A competitive inhibitor competes with the substrate for binding at the enzyme's active site. A noncompetitive inhibitor binds at a site other than the active site.

Competitive inhibition occurs when molecules that are very similar to the substrate molecules bind to the active site and prevent the actual substrate from binding. Penicillin, for example, is a competitive inhibitor that inhibits the active site of an enzyme used by many bacteria to build their cell... In repression.

Noncompetitive inhibition, a type of allosteric regulation, is a type of enzyme inhibition in which an inhibitor binds to an allosteric site, resulting in decreased enzyme efficacy. An allosteric site is simply one that differs from the active site—the location where the substrate binds.

At what point during resuscitation is a cardiac monitor recommended to assess the baby's HR?.

Answers

The baby's heart rate should be checked once more after 60 seconds of chest compressions. The most precise way to measure heart rate while performing chest compressions is through continuous ECG monitoring.

International resuscitation guidelines for neonatal resuscitation advise determining a newborn's heart rate (HR) by using a stethoscope to listen to the precordium, feeling for pulsations at the base of the umbilical cord, or feeling the brachial or femoral pulses.

The Neonatal Resuscitation Program (NRP) and other international neonatal recommendations use predetermined HR targets of 100 and 60 beats per minute (bpm), respectively, to start PPV and chest compressions.

Biological evolution is the process by which populations of organisms change over time. In this lab, you were able to observe how a population of peppered moths can change based on their environmental surroundings. Why do these types of changes/adaptations occur?

Answers

Answer: These types of changes/adaptations occur in order for the peppered moths to camouflage which gives them a higher chance of surviving and producing offspring.

Explanation: When the environment changed, due to pollution, the color of the moth population shifted because light-colored moths became easier to see so they were eaten more often. The darker moths were better camouflaged and more likely to survive and produce offspring. Organisms that survive have a better chance of reproducing so the population continues to grow.

how does one side of the dna strand compare with the other side of the dna strand?

Answers

The two sides of a DNA strand, also known as the "backbone," are composed of alternating sugar and phosphate molecules. The sugar in one strand is called deoxyribose and the other strand is composed of a base, which can be adenine, thymine, guanine, or cytosine. These bases form the "rungs" of the DNA ladder and are held together by hydrogen bonds, which connect the two strands of DNA. The sequence of these bases on one strand determines the complementary sequence of bases on the other strand, which is what allows for DNA replication and the transmission of genetic information.

Pick one of these factors and explain what impact it has on how quickly a rock weathers.

Answers

Answer:

Thermal stress is one of the causes of weathering of rocks.

Explanation:

The disintegration or dissolving of rocks and minerals on the earth's surface is referred to as "weathering." Water, ice, acids, salts, plants, animals, and temperature variations are all weathering agents. After a rock has been broken down, a process known as erosion carries the rock fragments and minerals away. No rock on Earth is strong enough to withstand the pressures of weathering and erosion.

Weathering via mechanical means Rocks crumble as a result of mechanical weathering, also known as physical weathering and disaggregation. Water, whether liquid or solid, is a common mechanical weathering component. Liquid water, for example, can seep into cracks and fractures in the rock. Water will freeze if temperatures fall low enough. Water expands as it freezes. The ice then functions as a wedge. It gradually enlarges the fissures and breaks the rock. When ice melts, liquid water erodes the rock by taking away the microscopic pieces that were lost in the break. This particular process (the freeze-thaw cycle) is referred to as "frost weathering" or cryofracturing.

Temperature changes, known as "thermal stress," can also contribute to mechanical deterioration. Temperature changes cause rocks to expand (with heat) and compress (with cold). The structure of the rock diminishes when this occurs repeatedly. It collapses over time. Thermal stress is especially dangerous in rocky desert terrain. As the temperature varies from day to night, the exterior layer of desert rocks is subjected to repetitive stress. Exfoliation occurs when the outer layers flake off in thin sheets. Exfoliation contributes to the production of Bernhardt's, one of the most spectacular aspects of weathered and eroded landscapes. Bornhardts are towering, domed, solitary rocks that are commonly found in tropical regions.
