How is infiltration related to groundwater?
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?
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.
Explanation:
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.
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.
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:
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.
A DNA sequence that is responsible for the initiation of transcription in a cell-type specific manner is:_____.
Answer:
Promoter.
Explanation:
It is promoter because Promoter is a DNA sequence where's the gene transcription begins. It is the
DNA sequence which RNA polymerase binds or join to
so as to begin transcriptionn of a gene . It is a region where the regulatory elements i.e protein will bind to and the Promoter sequences are found directly upstream or at the end of 5' of the transcription initiation site. This can also encode RNA such as mRNA, trans and so on.

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?
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
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
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.

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
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.
