D) an invasive species

Answer:

The correct answer is option B, that is, Calvin cycle.

Explanation:

The light-independent reaction or photosynthetic carbon reduction of photosynthesis is termed as the Calvin cycle. In this reaction, the compounds get transformed to glucose, and at the same time regenerated ribulose bisphosphate gets produced as the end product with ADP from ATP.

ADP is obtained from the molecules of ATP, and 1 molecule of glucose is generated as the end product in the reduction phase of the process. On the other hand, in the regeneration phase, the molecules of RuBP regenerates and the molecules of ATP get convert again to the molecules of ADP.

Dmitri Mendeleev first organized the periodic table by atomic mass. Later, Henry Moseley improved the design of the periodic table by organizing the columns into families.

Dmitri Mendeleev (1834-1907), in 1869, while in Russia, had the same idea as Meyer, who was studying in Germany. He more meticulously arranged a periodic table where the 63 known chemical elements were arranged in columns based on their atomic masses.

With this information, we can conclude that Dmitri Mendeleev first organized the periodic table by atomic mass. Later, Henry Moseley improved the design of the periodic table by organizing the columns into families.

Answer:

What I expect to happen to Peru's fishing industry during El Niño and La Niña is it will suffer greatly because with less nutrients there will be the less  plankton and without this important food source for the fish hence there will be no fish to catch.

Explanation

Sorry this answer probably won't be of use to you anymore.

Peru's fishing industry will be on a decline if there are less plankton present in the water ecosystem.

They are referred to diverse collection of organisms found in water and serves as food source for fishes.

When there are less plankton, there will be less food for fish which will lead to a decrease and also a decline in Peru's fishing industry.

Trisomies occur due to errors in meiosis where chromosomes fail to separate properly, resulting in an abnormal number of chromosomes in the resulting cells.

During meiosis I, homologous chromosomes separate and are distributed to two different daughter cells. This results in the formation of haploid cells, each with one set of chromosomes. In meiosis II, sister chromatids separate and are distributed to different daughter cells, resulting in the formation of four haploid cells.

Trisomies occur when there is an error during meiosis, specifically during the separation of homologous chromosomes or sister chromatids. In the case of trisomy 21, also known as Down syndrome, there is an extra copy of chromosome 21. This occurs when the homologous chromosomes fail to separate properly during meiosis I, resulting in one cell with an extra chromosome 21 and another cell with one less chromosome 21. When these cells divide in meiosis II, the cell with an extra chromosome 21 will produce two daughter cells with an extra chromosome 21, resulting in trisomy 21.

Similarly, poly X syndrome occurs when there is an extra X chromosome in females. This occurs when there is a failure in the separation of sister chromatids during meiosis II. The resulting cell will have an extra X chromosome, resulting in poly X syndrome.

Astronomers have learned about elements in stars by analyzing their spectra.Spectroscopy is the scientific analysis of electromagnetic radiation of a material or an object.

It is the analysis of the distribution of colors of a light source or other electromagnetic radiation components, as a function of frequency or wavelength. It may be divided into different categories on the basis of the wavelength range it spans, including ultraviolet, visible, near-infrared, and infrared spectroscopy.

Astronomers use spectroscopy to study the spectra of stars to determine their chemical composition. When a beam of light is passed through a prism, it is dispersed into its component colors, producing a spectrum. Each element emits light at a specific wavelength, creating a unique spectral fingerprint that can be used to identify it.

One way that ancient people did not use to classify plants and animals is based on their genetic or evolutionary relationships.

Ancient classifications of plants and animals were typically based on observable characteristics such as appearance, behavior, and usefulness. They relied on morphological features like shape, size, color, and habitat to group organisms together.

Ancient classifications often focused on practical aspects such as medicinal uses, edible properties, or cultural significance. For example, plants might have been classified based on their healing properties or their suitability for food or construction materials. Animals might have been categorized based on their physical traits, such as their ability to fly or swim.

However, ancient people did not have access to the scientific understanding of genetics or the tools to study DNA sequences, which are fundamental in modern taxonomy. They lacked the knowledge of shared ancestry and evolutionary relationships that form the basis of modern classification systems such as cladistics and phylogenetics.

Therefore, the genetic or evolutionary relationships between organisms were not considered in ancient classifications, distinguishing them from the approach used in modern biological taxonomy.

The macromolecule that carries genetic information is DNA (Deoxyribonucleic acid).

The macromolecule that carries genetic information in living organisms is Deoxyribonucleic acid (DNA). DNA is a double-stranded helical structure composed of nucleotides. Each nucleotide consists of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases: adenine (A), thymine (T), cytosine (C), or guanine (G). The specific sequence of these bases along the DNA molecule forms the genetic code.

DNA carries the instructions for the development, functioning, and reproduction of all living organisms. It contains the information that determines an individual's inherited traits, such as physical characteristics, susceptibility to diseases, and various biological processes. DNA is found within the cell nucleus, organized into structures called chromosomes.

During cell division, DNA is replicated and passed on to daughter cells, ensuring the transmission of genetic information from one generation to the next. Through the process of gene expression, DNA provides the template for the synthesis of RNA and proteins, which are vital for the structure and function of cells and organisms. Thus, DNA serves as the primary carrier and custodian of genetic information.

Answer:

Explanation:

The number of organisms near the top of the energy pyramid is usually small, because most of the energy produced is lost due to factors such as exercise and heat. This energy loss occurs multiple times when passing through the pyramid, forcing consumers near the top to require more food. This creates a pyramid with the third consumer at the top and the producer at the bottom.

The anesthesia has blocked the Inter-neurons from carrying signals to the brain.

They deactivated nerves in a certain area

The anesthesia has blocked sensory neurons from carrying signals to the brain.    

Anesthesia is usually given during tooth extraction, a root canal procedure, or while performing a tooth surgery. When anesthesia is injected it causes loss of sensation, temporarily without depressing the consciousness.

They inhibit the sodium inflow which is necessary for generating impulse. Without the generation of nerve impulses, the signal for pain is not transmitted.

Apart from being useful in certain medical procedures, anesthesia can cause several side effects such as headache, nausea, dizziness, insomnia, fever, and itching.

For a dental procedure like a root canal, anesthesia is usually injected into the inner cheek or gums.

Unpasteurized fruit juice can be contaminated if there are pathogens in or on the fruit used to make it. True.

Pasteurization, also known as pasteurisation, is a method of food preservation in which foods, both packaged and unpackaged (such as milk and fruit juices), are subjected to a mild heat treatment, typically at a temperature of less than 100 °C (212 °F), in order to destroy pathogens and increase shelf life. Although most bacterial spores survive the procedure, it is designed to kill or inactivate microorganisms and enzymes, including vegetative bacteria, that contribute to food spoiling or disease risk. The procedure bears the name of Louis Pasteur, a French scientist who discovered via his study in the 1860s that heating wine would destroy undesirable germs.
