High frequency has a ________ wavelength. low frequency has a ______ wavelength. question 1 options: short, long long, short medium, short long, medium
High frequency has a short wavelength. low frequency has a long wavelength.
Frequency is defined as the number of waves that pass a specific point in unit time. The SI unit used in case of frequency is Hertz (Hz). If the frequency is 1 Hz, it depicts that only 1 wave passed the point at a specific amount of time.
Wavelength is the distance between two consecutive crests or troughs of a wave. The representation of wavelength is done by the symbol λ (lambda). The frequency and wavelength have an inverse relation. This can be observed by the formula
ν (frequency) = c (speed of light) / λ (wavelength).

You have 23 pairs of chromosomes in your body cells. Why do your chromosomes occur in pairs? Where does each chromosome in the pair come from?
Answer:
You have your chromosomes in pairs because you get 23 from each parent.
Your chromosome pairs come from your parents, 23 from your mom (egg), 23 from your dad (sperm). Which totals to 46 chromosomes in your body.
how does the concentration of prokaryotic cells at the surface of pelagic water compare with the concentrations at depths below 1000 m?
The concentration of prokaryotic cells at the surface of pelagic water compare with the concentrations at depths below 1000 m as option B: there is a decrease in concentration with increasing depth.
Prokaryotic cell counts often peak in sediments close to the surface and then rapidly decline as depth increases. However, the average cell concentration is still extremely significant at the typical marine sediment depth of 500 m. Prokaryotic cells are believed to have decreased by 97% due to the preferential removal of the most easily degradable organic matter components during burial. As a result, the remaining organic matter becomes more resistant and can only support a smaller prokaryotic population.
The Proteobacteria genus contains the majority of prokaryotic organisms in the ocean. These creatures have a variety of adaptations, such as compressible lungs and swim bladders that resemble lungs, to help them deal with the intense water pressure in their deep-water habitat.

To reduce one molecule of o2 how many electrons passed through electron transport chain.
To reduce one molecule of O2 it takes 4 electrons.
Electron transfer is the last process of aerobic respiration that occurs in the inner membrane of mitochondria. In electron transport, the process of making ATP occurs which will later be used by cells to carry out activities in the body. The material for making ATP comes from NADH and FADH2 which are produced in glycolysis, oxidative decarboxylation, and the Krebs cycle. O2 acts as the final electron acceptor which will later form H2O which will be removed from the cell.
In electron transport, NADH and FADH are utilized in a series of oxidation-reduction reactions until finally used to reduce O2 to H2O. This redox reaction involving various protein complexes in the mitochondrial inner membrane is referred to as oxidative phosphorylation. The energy released in this redox process is converted into a high-energy molecule, namely ATP. To reduce one molecule of O2 it takes 4 electrons.

The definitions are matched according:
Water diffuses across a partially permeable membrane from a high water concentration area to a low water concentration area until equilibrium is established. Molecules move over a partially permeable membrane from a high concentration area to a low concentration area until equilibrium is attained.
Osmosis occurs when molecules flow via a Partially permeable membrane with the help of a transport protein from a high concentration area to a low concentration area until equilibrium is attained.
Facilitated Diffusion: Molecules that pass across a partially permeable membrane with the help of a transport protein and require energy to move from a low-concentration area to a high-concentration area without achieving equilibrium.
Active Transport: Molecules that flow over a partially permeable membrane with the help of a transport protein and require energy from a low-concentration area to a high-concentration area without achieving equilibrium.
What is the use of osmosis?
By balancing the levels of water and intracellular fluids, osmosis assists in the stability of the organism's internal environment. Additionally, nutrients and minerals enter the cell through osmosis, which is necessary for cell survival.
It is used to preserve the freshness of fruits and meat. Salt preserves meat, fish, and vegetables, but sugar preserves fruits. Bacteria that infect them attack them swiftly.

The final temperature started out at 25°C would be 27.9°C, if 3000 J of energy is released from 1kg of air.
Equation
The ratio of a material's capacity to absorb heat to the change in temperature is known as heat capacity. In terms of the actual amount of material being taken into account, which is most frequently a mole, it is typically stated as calories per degree (the molecular weight in grams). Specific heat capacity is the heat capacity expressed in calories per gram.

what is one thing that members of the same species can do, that the other peers of organism cannot
Breeding between different species, although possible, is often complicated as it results in infertile or non-viable offspring. This usually occurs due to the difference in the karyotype.
The karyotype is the set of chromosomes that an organism possesses, for example, the human has 23 pairs of chromosomes (46 chromosomes).
For reproduction to be successful and give rise to healthy organisms, the parents must be of the same species (have the same number of chromosomes and these chromosomes must be homologous, i.e. have similar genes).
Therefore, unlike organisms of different species, the reproduction of 2 organisms of the same species can result in fertile offspring capable of reproduction.

The Trichonympha is a protozoan that breaks down the wood eaten by the termite and both organisms absorb the nutrients.
Symbiotic relationships are close associations formed by two species. They take many forms, including parasitism (in which one species benefits while the other suffers) and commensalism (where one species benefits and the other is neither harmed nor helped).
The protozoan Trichonympha lives in the termite's shelter and space. The Protozoa in the gut digest the wood on which the termite feeds. Without Trichonympha, the termite is unable to digest wood and dies. Trichonympha is a symbiotic flagellate of many termite species as well as the wood-feeding cockroach.

To drive molecular movement along the actin subunits of the thin myofilaments, the myosin head groups hydrolyse ATP.
Myosin's head domains are located on the thick filaments' surface and interact with actin in the thin filaments. A change in the working stroke of the actin-bound myosin head's conformation, which causes filament sliding, occurs. The myosin heads bind and hydrolyze ATP in addition to binding actin, which gives filament sliding its energy. Changes in the structure of myosin brought on by ATP binding mediate the conversion of chemical energy to movement.
