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.

Breakdown of dead/decomposing materials into ammonia?
Answers
Answer:
Breakdown of dead materials into ammonia occurs due to decomposers.
Explanation:
Decomposers are the organisms which are responsible for the breakdown of dead bodies of plants and animals produces ammonia by consuming the nitrogen present in that dead body of plant and animals through the process of ammonification. The ammonium produced is then converted into nitrates by the nitrifying bacteria and this nitrates is used by the plants for making amino acids and enzymes.

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.

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]

chemical composition of the Rough endoplasmic reticulum
Answers
Answer:
The rough endoplasmic reticulum consists of two dimensional flattened sacs formed from phospholipids and ribosomes.
Explanation:
Genes within DNA are expressed through transcription and translation of the genetic code.
The rough Er contains important machinery in gene expressions, Ribosomes embedded in a lipid membrane. These are small sub cellular organelles that carry out a specific function of protein manufacturing and modulation. They contain the translocon complex, integral to the translation process
The endoplasmic retuculum consists of folded phospholipid membrane sheets or cisternae- these are mainly two dimentional, and form flat sacs.These provide small specific environments from the cytosol in the cytoplasm- they span the entire cytoplasm.

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.

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.
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.

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.
