The Correct Answer Is C

Explanation:

All Three Aspects are related to Air.

Air has mass, applies pressure, and takes up space. Therefore, option (C) describes the characteristics of air.

Air has particular qualities or features and is a mixture of gases, water vapor, and other elements. Gases make up air, which has mass, pressure, and weight as well as the ability to be compressed and be affected by temperature.

Nearly all of the air is made up of the molecules of two separate elements, nitrogen and oxygen. Carbon dioxide and argon, in trace levels, make up the remainder. (Trace amounts of other gases, including neon, helium, and methane, are also present.)

Answer:

Answer is bile

Cholecystokinin is secreted by cells of the upper small intestine. Its secretion is stimulated by the introduction of hydrochloric acid, amino acids, or fatty acids into the stomach or duodenum. Cholecystokinin stimulates the gallbladder to contract and release stored bile into the intestine.

Depending on the phylogenetic tree, the two species that are most closely related are option c. Angus cattle and white-tailed deer.

Angus cattle and white-tailed deer should be considered as the two species as these are closely related since it should both be taxa species that represent the close relationship in the phylogenetic tree.

Also, phgmy hippotamus and while tail dear should be less closely related as compared to the option c.

Hence, the option c is correct.

Answer:

The effects of anoxia on water and solute transport across excised roots of young maize plants (Zea mays L. cv. Tanker) grown hydroponically have been studied. With the aid of the root pressure probe, root pressure (Pr), root hydraulic conductivity (Lpr), and root permeability (Psr), and reflection (σ sr) coefficients were measured using potassium nitrate (a typical nutrient salt) and sodium nitrate (an atypical nutrient salt) as solutes. During a period of 10–15 h, anaerobic treatment (0.0–0.2 g O2·m-3 in root medium) caused a decrease of root pressure by 0.01–0.28 MPa (by 10–80% of original root pressure) after a short transient increase. For a time period of 5 h, the decrease in the stationary root pressure was not reversible. Under anaerobic conditions, roots still behaved like osmometers and were not leaky. The root hydraulic conductivity measured in osmotic experiments (osmotic solute: NaNO3) was smaller by one to two orders of magnitude than that measured in the presence of hydrostatic gradients. Both the osmotic and hydrostatic hydraulic conductivity decreased during anaerobic treatment by 28 and 44%, respectively, at a constant reflection coefficient of the solutes (σ sr=0.3−1.0). As with root pressure, changes in root permeability to water and solutes were not reversible within 5 h. Under aerobic conditions and at low external concentrations (31–59 mOsmol·kg-1), osmotic response curves were monophasic for KNO3, i.e. there was no passive uptake of solutes. Response curves became biphasic at higher concentrations (100–150 mOsmol·kg-1)- For NaNO3, response curves were biphasic at all concentrations. Presumably, this pattern was a consequence of the fact that potassium had already accumulated in the xylem. During anoxia, accumulation of potassium in the xylem was reduced, and biphasic responses were also obtained at lower potassium concentrations applied to the medium. The results are discussed in terms of a pump/leak model of the root in which anoxia affects both the active ion pumping and the permeability of the root to nutrient salts (leakage). The effects of anaerobiosis on the passive transport properties of the root (Lpr, Psr, σ sr) are in line with the recently proposed ‘composite transport model of the root’.

Answer:

The temperature of the beaker with water should change very little compared with the beaker with just air, demonstrating that the heat capacity of water can resist changes in air temperature.

Explanation: EDMENTUM/PLATO ANSWER

The two beakers unequally respond to the hot air. This is because the beaker full of water has a heat holding capacity that can resist the alteration in the temperature when hot air is blown onto it.

A Thermometer may be defined as an instrument that can measure the temperature of a particular location significantly.

According to the question, the temperature of the beaker which is full of water changes very little as compared to the beaker which is empty.

Therefore, it is well described above.

Answer:

Root tubers

Explanation:

Firstly, amyloplasts are a type of plastids whose function is to produce and store starch granules. Amyloplasts are found to be numerous in the cells of storage tissues in certain plants. The ROOT TUBERS of some plants like potato stores carbohydrate in form of starch in the amyloplast organelles present in their cells.

According to this question, the ROOT, which contains numerous starch-storing organelles called AMYLOPLAST, primarily functions to store food for the plant.

Answer:

Green house effect.

The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things that makes Earth a comfortable place to live.

Answer:

it is the natural process that warms the Earth's surface. The process is called the greenhouse effect because the exchange of incoming and outgoing radiation that warms the planet works in a similar way to a greenhouse

Explanation:

Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"1 — warming that results when the atmosphere traps heat radiating from Earth toward space.

Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as "forcing" climate change. Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as "feedbacks.

Water vapor. The most abundant greenhouse gas, but importantly, it acts as a feedback to the climate. Water vapor increases as the Earth's atmosphere warms, but so does the possibility of clouds and precipitation, making these some of the most important feedback mechanisms to the greenhouse effect.

Carbon dioxide (CO2). A minor but very important component of the atmosphere, carbon dioxide is released through natural processes such as respiration and volcano eruptions and through human activities such as deforestation, land use changes, and burning fossil fuels. Humans have increased atmospheric CO2 concentration by 47% since the Industrial Revolution began. This is the most important long-lived "forcing" of climate change.

Methane. A hydrocarbon gas produced both through natural sources and human activities, including the decomposition of wastes in landfills, agriculture, and especially rice cultivation, as well as ruminant digestion and manure management associated with domestic livestock. On a molecule-for-molecule basis, methane is a far more active greenhouse gas than carbon dioxide, but also one which is much less abundant in the atmosphere.

Nitrous oxide. A powerful greenhouse gas produced by soil cultivation practices, especially the use of commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass burning.

Chlorofluorocarbons (CFCs). Synthetic compounds entirely of industrial origin used in a number of applications, but now largely regulated in production and release to the atmosphere by international agreement for their ability to contribute to destruction of the ozone layer. They are also greenhouse gases.

Answer:

Dominant: 20, Recessive: 20

Explanation:

The case shown in the question above explores simple Mendelian traits, since it shows a population where individuals of the same species present the dominant allele (R- red) and the recessive allele (r- white). We can project, then, that this population has an allele balance, where it is possible to find 20 red beans, which have the dominant allele and 20 white beans, which present the recessive allele.

Answer:

a high ionization atom

Explanation:

Answer

It would be more likely to react with an atom with low ionization energy. Electronegativity refers to an atoms ability to attract electrons to it. If it has a high electronegativity, it has an easier time attracting electrons. This is important when it comes to forming bonds in which electrons are being shared (like in covalent bonds).

Answer:

b.

Explanation:

Answer:

The proper order is:

A. DnaA proteins bind to the origin of replication, resulting in the separation of the AT-rich region.

B. DNA helicase breaks the hydrogen bonds between the DNA strands, topoisomerases alleviate positive supercoiling, and single-strand binding proteins hold the parental strands apart.

C. Topoisomerases unravel the intertwined chromosomes, if necessary.

D. Primase synthesizes one RNA primer in the leading strand and many RNA primers in the lagging strand, and DNA polymerase III synthesizes the daughter strands of DNA.

E. DNA polymerase I removes the RNA primers and fills in that region with DNA, and DNA ligase covalently links Okazaki fragments together.

F. Replication continues until the two replication forks meet on the other side of the circular bacterial chromosome.

Explanation:

The process of DNA replication in prokaryotes starts at a point called ORIGIN OF REPLICATION. This site is where certain proteins recognize and bind to in order to kickstart the replication process. The following are orderly processes of DNA replication.

- DnaA proteins bind to the origin of replication, resulting in the separation of the AT-rich region.

- DNA helicase breaks the hydrogen bonds between the DNA strands to form two replication forks, topoisomerases prevent supercoiling of these separated DNA, and single-strand binding proteins hold the parental single strands apart, hence, making sure that they do not rewind again.

- In case DNA rewinds, topoisomerases unravel or disentangles the intertwined chromosomes, if necessary.

- DNA Primase synthesizes one RNA primer in the leading strand and many RNA primers in the lagging strand,which allows DNA polymerase III synthesize the daughter strands of DNA. Note that the synthesis of nucleotides on threading strand is continuous while nucleotides are synthesized in small fragments called OKAZAKI FRAGMENTS, on the lagging strand.

- DNA polymerase I removes the RNA primers and replaces with synthesized DNA in that region, and DNA ligase covalently links the Okazaki fragments (small fragments of DNA) together.

- Replication continues until the two replication forks meet on the other side of the circular bacterial chromosome.
