Why are leaves of water lily coated with wax on the upper surface?

Answers

Answer 1

Answer:

The wax creates an outer layer of zero friction surface helping the water lily leaves float on the water surface, the wax also creates a shiny coating that reflects and lowers the temperature of the water and also prevents water loss by evaporation and helps in prevention of other plant diseases.

Identify one process that causes clouds to form in the moist air rising along the frontal boundaries of the low-pressure system.

Answers

Answer and Explanation:

The fronts are imaginary lines that separate two air masses of different temperatures. It takes too long for these two masses to mix, causing numerous atmospheric phenomena.

A hot air mass meets a cold air mass. The cold air is heavier and takes a wedge shape under the hot air that rises following a kind of ramp that constitutes the front line.

In the contact area, the hot air cools to the point of condensation and forms clouds that cause precipitation. These warm fronts originate weak but continuous rains.

To support the ecosystem in the previous question, botanical gardens are propagating these trees for sale. Although seeds have been collected, the commercially available plants are from cuttings and tissue culture. Based on the life cycle of conifers, why is it not practical to reproduce Wollemi pines from seed or even to sell the seeds?

Answers

Answer:

A tree that possesses scale or needle-like leaves and cones that remains green throughout the year is known as a conifer. Some of the examples of conifers are cedars, junipers, redwoods, pines, etc. These trees have great economic importance as they are the prime sources of turpentine and resins, and are also a great source of softwood.  

It is not practical to cultivate the Wollemi pines from their seeds, as the majority of the seeds that fall from the cones of Wollemi are not viable, and their cultivation may even consume many months. The species mentioned is also considered as endangered, therefore, it will not be feasible to cultivate them via the help of seeds.  

3. Which of the following are NOT types of microorganisms?
a. Prions
b. Viruses
c. Bacteria
d. Earthworms

Answers

Answer:

d. Earthworms

Explanation:

Think about it: have you ever actually seen a prion, virus, or bacterium? No, because they can't be seen with the naked eye. Microorganism means that it's too small (hence the prefix micro-) to see.

Prions are little misfolded proteins. Viruses are nonliving things made up of a protein and nucleic acid. Bacteria are little prokaryotic microorganisms.

How is electricity generated in the simulation?

Answers

Answer:

(LONG RESPONSE!)

In this work, several simulations and analyses are carried out to investigate the feasibility of generating electricity from underwater sea currents at Istanbul Bosphorus Strait. Bosphorus is a natural canal which forms a border between Europe and Asia by connecting Black Sea and Marmara Sea. The differences in elevation and salinity ratios between these two seas cause strong marine currents. Depending on the morphology of the canal the speed of the flow varies and at some specific locations the energy intensity reaches to sufficient levels where electricity generation by marine current turbines becomes economically feasible.

In this study, several simulations are performed for a 10 MW marine turbine farm/cluster whose location is selected by taking into account several factors such as the canal morphology, current speed and passage of vessels. 360 different simulations are performed for 15 different virtual sea states. Similarly, 8 different configurations are analyzed in order to find the optimum spacing between the turbines. Considering the spatial variations in the current speed within the selected region, the analyses are performed for three different flow speeds corresponding to ±10% change in the average value. For each simulation the annual energy yield and cluster efficiency are calculated.

Answer:

They waited before crossing a busy street

Explanation:

Assume the graph looks like the one below.

It shows that, from Point B to C, the distance they were from home did not change.  They had stopped.

A possible interpretation is that they waited before crossing a busy street.

If they had begun accelerating, BC would have been steeper than AB.

If they had slowed their walk, BC would still point up. However, its slope would be less than that of AB.

If they had returned home, BC would point down and to the right.

 

After the protein has fallen off the operon, the ____________ can then transcribe the DNA into mRNA.

Answers

Answer:

The genetic material of most organisms is DNA, which stores the information required for the development, functioning, and reproduction of the organism. DNA is a long piece of nucleotides where both coding and non-coding regions can be identified within the nucleotide sequence. The coding regions contain the information for the production of functional proteins in the organisms. The process of production of the polypeptide chain of the protein inside the cell is known as protein synthesis. Transcription of DNA into mRNA and translation of mRNA into an amino acid sequence of the protein are the sequential steps of the protein synthesis.

Explanation:

A patient is suspected of having low stomach acid, a condition known as hypochloridia. To determine whether the patient has
this condition, her doctors take a 16.00 mL sample of her gastric juices and titrate the sample with 3.76 x 10-4 M KOH. The
gastric juice sample required 5.87 mL of the KOH titrant to neutralize it.
Calculate the pH of the gastric juice sample. Assume the sample contained no ingested food or drink which might otherwise
interfere with the titration.

Answers

Answer:

pH of the gastric juice

[tex]3.86[/tex]

Explanation:

As we know,

In an acid base titration, the number of milimoles of acid is equal to the number of milimoles of base.

Milimoles [tex]=[/tex] Molarity [tex]*[/tex] Volume

Molarity of gastric juices [tex]*[/tex] Volume of gastric juices  [tex]=[/tex]  Molarity of KOH [tex]*[/tex] Volume of KOH

Substituting the given values in above equation, we get -

[tex]16 * X = 5.87 * 3.76 * 10^{-4}\\[/tex]

X represents the molarity of gastric juices

[tex]X = \frac{5.87 * 3.76 * 10^{-4}}{16} \\X = 1.379 * 10^{-4}[/tex]

pH of gastric juices is equal to log [tex]1.379 * 10^{-4}[/tex]

[tex]= - log 1.379 * 10^{-4}\\= - [-3.86]\\= 3.86[/tex]

As a scientist working for an anti-bioterrorism task force, you are asked to evaluate some biological samples for the presence of Yersinia pestis, the organism that causes the plague. After confirming that the samples do contain Y. pestis, you instruct your team to begin sequencing the strain. Since the genome sequence of Y. pestis is already known, why would sequencing this strain be useful?

Answers

Answer:

To gather relevant knowledge about their origin and to determine if the strain has been genetically modified.

Explanation:

A researcher researching with the anti-bioterrorism working group, they are required to assess certain blood specimens only for existence of Yersinia pestis, the organisms which causes the disease.

Since verifying that perhaps the varieties showed Y. Pestis, they are instructing their group to start sequence alignment the strains. So, this is to collect specific knowledge about their origin and to assess if the strain has also been genetically modified.

In the conifer forest just below the alpine zone of a mountain top, two closely related species of birds that feed on small flying insects have been living together for millions of years. A local naturalist notices that the beak sizes differ on the two birds. The species that eats mosquitoes has a small delicate beak, and the species that eats robber flies (bigger than mosquitoes) has a very large beak. By accident, the naturalist stumbles upon a fossilized bird on the mountain that looks like it could be the ancestor of both species except its beak is neither small nor large, but intermediate in size. What principle could be at work in shaping the beaks of these birds? a. competition b. ecological niche development c. coevolution d. character displacement e. all of the above

Answers

Answer: d. character displacement

Explanation:

Character Displacement this is an evolutionary divergence which usually occurs when two similar species inhabit the same environment. This circumstance occurs where differences among similar species whose circulation in an environment overlap geographically are feature in regions where the species co-occur, but tend to be minimized or lost where the species' circulations do not overlap. Which is same case as that of the birds.

Which of the following are features of nucleosomes? A nucleosome contains approximately 20 base pairs of DNA. The DNA in a nucleosome is wound around eight histone proteins. Between nucleosomes is a stretch of DNA called "linker DNA". A nucleosome contains 8 different types of histones. In a nucleosome, DNA is wrapped 4 times around the histone core. H1 seals off where DNA enters and leaves the nucleosome. Nucleosomes contribute to DNA packing. Nucleosomes in chromatin are arranged in straight, side-by-side chains. Nucleosomes are about 10000 Angstroms in diameter. Histones have tails that stick out and can be modified, affecting DNA expression.

Answers

Answer:

The correct answers are "The DNA in a nucleosome is wound around eight histone proteins", "Between nucleosomes is a stretch of DNA called "linker DNA", "H1 seals off where DNA enters and leaves the nucleosome", "Nucleosomes contribute to DNA packing", and "Histones have tails that stick out and can be modified, affecting DNA expression".

Explanation:

Nucleosomes are comprised of DNA and histones that in conjunction form structural units of the chromosomes. The DNA in a nucleosome is wound around eight histone proteins, which are known as the histone octamer.  Between nucleosomes is a stretch of DNA called "linker DNA", which is an unwrapped DNA that can be between 10 to 50 base pairs long. H1, one of the four types of histone, seals off where DNA enters and leaves the nucleosome serving as an anchor to the complex. Nucleosomes contribute to DNA packing by wrapping the DNA and forming the structural units of the chromosomes.  Histones have tails that stick out and can be modified, affecting DNA expression; which are known as "histone tails" located in the N-terminal side and where higher order structures are arranged.
