the base would be the beginning of a thing right?
and if it is then plants would be the base
but if it's not then I'm sorry,
but if it's the thing that all the things can eat (except plants) then maybe lizards

Production of ____________ allows streptococcus mutans to colonize the mouth.
The production of Dextran allows Streptococcus mutans to colonize the mouth.
What is Dextran?Dextran is a water-insoluble glucan that is created by some lactic acid bacteria using the enzyme dextransucrase. Streptococcus mutans are the most well-known producers of dextran. They contribute to the formation of dental plaque and tooth decay because dextran is water-insoluble and accumulates on the teeth's surface.
In summary, the production of Dextran allows Streptococcus mutans to colonize the mouth.

explain the basic functions of the human immune system , including specific and non spefic immune rewsponse , vaccines , and antibiotics
The basic function of the human immune system protects against foreign substances that cause infections and diseases, it is divided into two parts; non-specific (innate) immunity, and specific (adaptive) immunity.
The non-specific immune response is the body's initial response to an infection. It includes physical barriers like skin and mucus, as well as specialized cells such as neutrophils and macrophages that engulf and destroy invading pathogens. These cells are also responsible for releasing cytokines that help activate the immune system's specific response. The specific immune response, which is triggered by the presence of specific antigens on pathogens, involves the production of antibodies by B cells and the activation of T cells, which help coordinate the immune response.
Vaccines work by introducing harmless antigens to the immune system, triggering a specific immune response that generates memory cells. Antibiotics are drugs that help kill bacteria by disrupting their cell walls or metabolic pathways. In conclusion, the human immune system is a complex network of cells and molecules that work together to protect against foreign invaders, and its effectiveness can be improved by vaccination and antibiotics.

Which of the following is/are needed for initiation of RNA synthesis? Choose one: O A. Sigma factor alone OB. Neither RNA polymerase nor sigma factor O C. RNA polymerase and sigma factor O D. RNA polymerase alone
RNA polymerase and sigma factor are needed for initiation of RNA synthesis, option C is correct.
The initiation of RNA synthesis requires the presence of both RNA polymerase and a sigma factor. RNA polymerase is responsible for catalyzing the formation of RNA molecules during transcription. However, RNA polymerase alone is insufficient for proper initiation of transcription.
The sigma factor plays a crucial role in recognizing and binding to the specific promoter region of the DNA, thereby guiding RNA polymerase to the correct site for transcription initiation. It helps in positioning the RNA polymerase at the promoter site and assists in the separation of DNA strands, allowing the initiation of RNA synthesis, option C is correct.

what does a frequency of recombination of 50etween two genes indicate?
The genes are located on sex chromosomes. The two genes are likely to be located on different chromosomes. All of the offspring have combinations of traits that match one of the two parents, Abnormal meiosis has occurred.
The frequency of recombination of 50% between two genes indicates that the two genes are likely to be located on different chromosomes, and abnormal meiosis has occurred.
Meiosis is the process of cell division that generates gametes such as sperm and eggs. During meiosis, homologous chromosomes exchange genetic information, resulting in new combinations of alleles. This exchange is known as recombination. The frequency of recombination between two genes is a measure of the likelihood of these genes being inherited together. When the frequency of recombination is 50%, it indicates that the two genes are likely to be located on different chromosomes.
This is because chromosomes assort independently during meiosis, and the probability of crossing over between two genes on different chromosomes is approximately 50%. If all offspring have combinations of traits that match one of the two parents, it indicates that no new combinations of alleles have been generated by recombination. This could be due to abnormal meiosis, such as non-disjunction or other chromosomal abnormalities that prevent the proper separation of chromosomes during meiosis.

Two imbalances that are related are ____________ and hypochloremia because additional Cl- must be excreted to the kidney tubules to buffer the high concentrations of H+ in the tubules.
Two imbalances that are related are metabolic acidosis and hypochloremia because additional [tex]Cl^-[/tex] must be excreted to the kidney tubules to buffer the high concentrations of [tex]H^+[/tex] in the tubules.
Metabolic acidosis is a condition characterized by an imbalance in the body's acid-base balance, resulting in an increased concentration of hydrogen ions ([tex]H^+[/tex]) in the blood. This leads to a decrease in the bicarbonate ([tex]HCO_3^-[/tex]) levels, which act as a buffer to maintain pH balance. Hypochloremia, on the other hand, refers to a low concentration of chloride ions ([tex]Cl^-[/tex]) in the blood.
In the context of these imbalances, the kidneys play a crucial role in maintaining acid-base balance. To compensate for the excess [tex]H^+[/tex] ions in metabolic acidosis, the kidneys excrete more [tex]H^+[/tex] ions into the tubules. However, the excretion of [tex]H^+[/tex] ions requires a counter-ion, such as [tex]Cl^-[/tex].

why dont plants photosynthesise in the dark
Plants respire all the time, whether it is dark or light, because their cells need energy to stay alive. But they can only photosynthesize when they have light.
The oxidation of water occurs during photosynthetic electron transport during the light reactions of photosynthesis. In the absence of a source of light energy (dark reactions have no direct requirement for light energy), oxygen is not produced.
