How is infiltration related to groundwater?

Answers

Answer:

Ground water comes from rain water and snow that land on the surface and perlocate down into the soil and than becomes ground water. Infiltration is the process of the water entering the soil therefore without infiltration ground water wouldn't be able to be made as no water would go through the soil

Explanation:

Basically inflitration is the process of water going through the soil and into the earth and once it goes deep enough into the earth and passes through more soil it is considered groundwater.

why are colonial organisms not truly multicellular?​

Answers

Answer:

Colonial Organisms

The difference between a multicellular organism and a colonial organism is that the individual organisms that form a colony or biofilm can, if separated, survive on their own, while cells from a multicellular organism (e.g., liver cells) cannot. This enables the colony to swim towards the light.

All based on research.

A researcher wishes to increase the half-life of a particular mRNA that she is transfecting into a eukaryotic cell line. How should this researcher accomplish this goal?

a. Inhibit RNA polymerase I.
b. Increase the length of the poly(A) tail of the mRNA prior to transfection.
c. Inhibit the spliceosomes in the cell.
d. Increase the length of the 5'; cap of the mRNA prior to transfection.

Answers

Answer:

b. Increase the length of the poly(A) tail of the mRNA prior to transfection.

Explanation:

Polyadenylation is the addition of a long chain of adenine (A) nucleotides at the 3' end during RNA processing. This resultant chain is known as poly(A) tail. A poly-A tail generally has a size of 100-250 residues long. The poly(A) tail increases the stability of the messenger mRNA prior to the translation by slowing down its degradation rate over time. The process of polyadenylation enables RNA transcripts to be exported from the nucleus in order to be translated by ribosomes in the cytoplasm.

Identify the locations within the human body for Hyaline, Elastic and Fibrocartilage.

Answers

Answer:

A flexible connective tissue, known as cartilage varies from bones in many ways, its microcomposition is less developed in comparison to the bone and is avascular. It is not supplied with nerves and thus depends upon the process of diffusion to attain nutrients. The three kinds of cartilage are fibrous, hyaline, and elastic.

Of these the most widespread kind is the hyaline cartilage, it looks like glass. It is witnessed in embryos, where the formation of bone takes place as hyaline cartilage, which ossifies later. In adults, it is found on the tips of the ribs, on the articular surfaces of the long bones, the parts of the skull, and the rings of the trachea.

Fibrous cartilage is witnessed in the pubic symphysis and intervertebral discs and exhibits many collagen fibers.

Elastic cartilage is witnessed in the internal support of the external ear and the epiglottis and is yellow, springy, and elastic in characteristics.

The retinohypothalamic path consists of a special population of retinal ganglion cells that have their own photopigment, called:

Answers

Answer:

melanopsin

Explanation:

this note might help you :

The retinohypothalamic tract (RHT) is a photic neural input pathway involved in the circadian rhythms of mammals. The origin of the retinohypothalamic tract is the intrinsically photosensitive retinal ganglion cells (ipRGC), which contain the photopigment melanopsin. The axons of the ipRGCs belonging to the retinohypothalamic tract project directly, monosynaptically, to the suprachiasmatic nuclei (SCN) via the optic nerve and the optic chiasm. The suprachiasmatic nuclei receive and interpret information on environmental light, dark and day length, important in the entrainment of the "body clock". They can coordinate peripheral "clocks" and direct the pineal gland to secrete the hormone melatonin.

information about melanopsin : Melanopsin is a type of photopigment belonging to a larger family of light-sensitive retinal proteins called opsins and encoded by the gene Opn4.[5] In the mammalian retina, there are two additional categories of opsins, both involved in the formation of visual images: rhodopsin and photopsin (types I, II, and III) in the rod and cone photoreceptor cells, respectively.

Explanation:

A 50 mL sample of soup was found to be contaminated with E. coli. A dilution of the soup was prepared by adding 14 mL of the soup to 20 mL of water. This was then diluted 1/60, and finally 10-3. Then .25 was added in to 2 plates. The first plate had a colony count of 72 and second had 65.


To do the dilution series does the 50 need to be added?

Answers

Answer:

The answer is "[tex]\bold{4.0 \times 10^7 \ \frac{CFU}{mL}}[/tex]"

Explanation:

The very first thing we must do is figure out where the plate was really a countable sheet.  By default, at least 30 and 300 colonists must have been on a computable plate. It is deemed incorrect beyond and below this range.  We also will pick the studded 0.25 size, leading towards 72 and 65 colonies. Now calculate the double average.

[tex]\to 72+ \frac{65}{2} = 68.5[/tex]

We need to calculate its dilution factor for both the second item. Increase for all of this  

All of the dilutions you also made:

[tex]\to \frac{7}{17} \times \frac{1}{60} \times \frac{1}{1000} \\\\= \frac{7}{1020000}\\\\= 6.8 \times 10^{-6}[/tex]

[tex]\to \frac{14 \ ml \ soup}{14 \ ml} + 20\ mL\\\\[/tex]

[tex]\to \frac{CFU}{mL} = \frac{Colonial \ number}{Dilution \ Factor \times Volume \ plated}\\\\[/tex]

            [tex]= \frac{68.5}{6.8 \times 10^{-6} \times 0.25 \ mL} \\\\ = 4.0 \times 10^7[/tex]

Which of the following is true of integral membrane proteins?
A. They lack tertiary structure
B. They serve only a structural role in membranes
C. They are loosely bound to the surface bilayer
D. They are usually transmembrane proteins
E. They are not mobile within the bilayer​

Answers

Answer:

D. They are usually transmembrane proteins

Explanation:

Membranes are made up of a phospholipid bilayer, cholesterol and various mimbrane proteins. The lipids consist of outward facing hydrophilic heads and inwards facing hydrophobic tails. Cholesterol molecules help maintain membrane fluidity.

Transmembrane proteins play an important role. These help to transport various molecules and ions like glucose, and Na+ across the selectively permeable bilayer. These are permanently embedded within the membrane as integral membrane proteins, and do not move around.

Compare the wind speeds of the edge of a hurricane on earth and the edge of the great red spot on jupiter what is your conclusion

Answers

Answer:

Jupiter is approximately 318 times bigger than the earth. So, it is expected that its hurricanes would be very massive as well.

Explanation:

A hurricane is a tropical cyclone, a storm with a very violent wind. It is labeled a cyclone because of its cyclic nature.

The Great Red Spot of Jupiter is a giant storm about twice as large as Earth, which in its southern hemisphere orbits the globe. This at least twice the speed of the most dangerous and most destructive hurricanes on Earth, which can produce wind speeds of approximately 280 km/h.

So it means that if there were to be a great red 'jupiterian' spot on earth it would blow the earth away.

where do plants get their nitrogen

Answers

Although there's plenty of nitrogen in the air, it's not in a form plants can use. They can only absorb nitrogen in the form of ammonium, nitrite, and nitrate. One way plants have access to these forms of nitrogens is decomposition of organic matter by soil organisms. Another source of usable nitrogen are mutualistic relationships between plants and bacteria. By providing nitrogen-fixing bacteria a place to live and feeding them with carbohydrates, plants get nitrogen in the form of ammonium. Plants that can do this include most legumes which form relationships with Rhizobium bacteria, and other plants like alder, bayberry, California lilac, and Russian olive that support Frankia bacteria on their roots.
There are also free-living nitrogen-fixing bacteria, as well as cyanobacteria that grow on the surface of plants or the soil, that add small amounts of plant-usable nitrogen to the soil. Lightning also generates usable nitrogen compounds.
Chemical fertilizer is a major source of plant-usable nitrogen. But other human activities, like the burning of fossil fuels and livestock operations, inadvertently produce widespread, nitrogen-enriched rainfall.

1 All of the following processes move carbon out of the biosphere and into the atmosphere, geosphere, or hydrosphere except:

a:respiration b:photosynthesis c:excretion d:decaying ​

Answers

Answer:

photosynthesis

Explanation:

it takes carbon into the biosphere

Photosynthesis doesn't move carbon out of the biosphere instead takes up carbon  and uses it for energy production in plants. Therefore, option (B) is correct.

What is photosynthesis?

During the process of photosynthesis, plants draw carbon dioxide (CO2) and water (H2O) from the atmosphere and the soil respectively. Within the plant cell, water undergoes oxidation, which results in the loss of electrons, whereas carbon dioxide undergoes reduction, which results in the accumulation of electrons. Because of this, the water is converted into oxygen, and the carbon dioxide is converted into glucose.

Photosynthesis powers plant growth. This mechanism transforms carbon dioxide, water, and soil minerals into cells. Plants generate oxygen and nourishment.

Therefore, option (B) photosynthesis move carbon out of the atmosphere and into the biosphere.

He stood for a moment, his lean, drawn face haggard in the light of the two hurtling moons.He looked hopelessly across the dark spaceport. It was a large one, for this ancient town of Syrtis was the main port of Mars. The forked light of the flying moons showed many ships docked on the tarmaca big liner, several freighters, a small, shining cruiser and other small craft. And for lack of one of those ships, his hopes were ruined!A squat, brawny figure in shapeless space-jacket came to Kenniston's side. It was Holk Or, the Jovian who had been waiting for him."What luck?" asked the Jovian in a rumbling whisper."It's hopeless," Kenniston answered heavily. "There isn't a small cruiser to be had at any price. The meteor-miners buy up all small ships here.""The devil!" muttered Holk Or, dismayed. "What are we going to do? Go on to Earth and get a cruiser there?""We can't do that," Kenniston answered. "You know we've got to get back to that asteroid within two weeks. We've got to get a ship here."Desperation made Kenniston's voice taut. His lean, hard face was bleak with knowledge of disastrous failure.The big Jovian scratched his head. In the shifting moonlight his battered green face expressed ignorant perplexity as he stared across the busy spaceport."That shiny little cruiser there would be just the thing," Holk Or muttered, looking at the gleaming, torpedo-shaped craft nearby. "It would hold all the stuff we've got to take; and with robot controls we two could run it.""We haven't a chance to get that craft," Kenniston told him. "I found out that it's under charter to a bunch of rich Earth youngsters who came out here in it for a pleasure cruise. A girl named Loring, heiress to Loring Radium, is the head of the party."The Jovian swore. "Just the ship we need, and a lot of spoiled kids are using it for thrill-hunting!"Kenniston had an idea. "It might be," he said slowly, "that they're tired of the cruise by this time and would sell us the craft. I think I'll go up to the Terra Hotel and see this Loring girl.""Sure, let's try it anyway," Holk Or agreed.With the Jovian clumping along beside him, Kenniston made his way from the spaceport across the ancient Martian city.Read the following lines from the text:And for lack of one of those ships, his hopes were ruined!This line suggests Kenniston isdesperate angry dramatic realistic In developing its future strategy, CVS is focusing on Amazon, which is expanding into the healthcare business.
