In microscopy, the term resolution In microscopy, the term resolution refers to the ability to distinguish fine structure and detail in a specimen. is only observed in stained specimens. refers to magnification when using the electron microscope. is the same as the total magnification of a specimen. is improved when longer wavelengths of light are employed.
Answer:
refers to the ability to distinguish fine structure and detail in a specimen
Explanation:
Resolution can be defined as the capacity of a microscope to distinguish detail. Resolution can be measured as the minimum distance between two distinct objects of a specimen which can still be observed as separate entities. Some important factors influencing microscope resolution include 1- objective numerical aperture, which is related to the angles of light that are collected by a lens (can be improved by using immersion oil), 2- degree of aberration correction, 3-magnification (i.e., degree of visual enlargement of an observed object), 4- contrast methodology, etc. In a light microscope, for example, the maximum resolution that can be reached is 200 nanometers (nm), being this limited by the wavelength of light waves due to diffraction, while the maximum magnification is generally x1500.

Dancing lemurs have an upright posture with legs that are much longer than their arms. They are great aerial acrobats as they swiftly leap from tree to tree. On the ground, they are not able to walk on their four legs instead they perform a sideways bounce on their two legs while holding their arms out for balance, mimicking their leaps from tree to tree. This is an example of ___________.
Answer:
Suspensory locomotion (suspensory behavior)
Explanation:
Suspensory locomotion, also known as suspensory behavior, is a concept that refers to several specialized forms of locomotion observed in some primates, and in other arboreal mammals, which involves hanging the body among tree branches, thereby distributing the body weight to different branches of the trees. Suspensory locomotion includes three specialized types of locomotion: brachiation, climbing, and bridging. It is an adaptive strategy that enables suspensory animals to travel faster and avoid predators during arboreal movement and foraging. Some examples of suspensory primates include, among others, lemur, spider monkey, Bornean orangutan, etc.

Answer:
A. The process of photosynthesis moves carbon from the atmosphere to the biosphere.
The ocean is the greatest carbon sink, storing about 38,000 gigatons of carbon per year.
D. Geologic processes such as eruptions move carbon from the geosphere to the atmosphere.
Explanation:
Photosynthesis is a process in which carbondioxide gas that is present in the atmosphere moves into the plant body for the production of food in the presence of sunlight. Volcanic eruption releases high amount of carbondioxide and carbonmonoxide gases in the atmosphere. The ocean is the greatest storage of carbon, storing about 38,000 gigatons of carbon per year.

This biome has the highest net primary productivity in part because of consistently warm temperatures and abundant sunlight
Answer:
The correct answer is Tropical Rainforest.
Explanation:
A Tropical Rainforest is described as a tall, warm, and dense forest near the equator. A tropical rainforest biome has several characteristics that identify it, they have rains that can occur throughout the year, their high average temperatures are identified, their abundant rainfall, they are constant throughout the months, which can reach 5000 mm in a only one year, in addition to having dense vegetation.Trees in the emergent layer enjoy as much sunlight as possible, enduring strong winds, extremely high temperatures, and little humidity. Tropical Rainforest aid in the absorption of carbon dioxide from the atmosphere, helping to maintain most of the natural life cycles necessary for subsistence on Earth.

Briefly describe an experiment that would allow you to test the hypothesis that increased predation by killer whales was the cause of the sea otter decline. Keep in mind the following key components of any good experiment:
a control (something to which to compare the treatment), replication (do it more than once), and consideration of confounding factors (what differences other than what you manipulate in your experiment?).
Answer:
Control environment having no fish, seal or squid only sea otter.
Explanation:
If a killer whale is present in the control environment means no food except sea otter so we can see a decrease in the population of sea otter because the killer whale feed on it. If a killer whale has more food available in the form of fish, squid and seal etc so they will not feed on sea otter and their population will be increasing with the passage of time but when the killer whale is present in an environment which has no fish, squid and seal etc to eat so they feed on the sea otter to survive and as a result the population of sea otter decline.

Explanation:
You are studying the genomes of deep sea organisms when you come across a brand new species of lantern fish. In the lab, you measure the percent of nucleotides in the nucleus that contain adenine as their base and that percent is 30%. 10. Calculate the percent of thymine nucleotides: _______________ 11. Calculate the percent of guanine nucleotides: _______________ 12. Calculate the percent of cytosine nucleotides: _______________
Answer:
Thymine = 30%
Guanine = 20%
Cytosine = 20%
Explanation:
DNA is a double-stranded molecule made up of long chains of nucleotides (A, T, G, C). Each chain is the strand. However, According to Chargaff, the amount of adenine in a DNA is equal to the amount of thymine while the amount of guanine equals the amount of cytosine. That is:
(A = T) + (G = C) = 100%
All together, they all make up 100%. According to this question, the percent of nucleotides in the nucleus was measured to contain adenine as their base which is 30%.
If Adenine is 30%,. Then Thymine is 30% as well.
A = T = 30+30 = 60%
Hence,
60% + G + C = 100%.
G + C = 100 - 60
G + C = 40%
Since, G = C, 40/2 = 20%. Hence, G = 20% while C = 20%
All together,
A = 30%
T = 30%
G = 20%
C = 20%

Explanation:
identify the individual who most likely exhibits symptoms of cystinuria
Answer: Individuals with a high concentration of cysteine in their urine, show symptoms of cystinuria.
Explanation:
Cystinuria is an hereditary and rare disease in which stones of an amino acid called cystine form mostly in the kidney but also in the ureter and bladder. This is a dimeric amino acid which is formed by two cysteine molecules linked by a disulfide bond. L-cysteine is a non-essential sulfuric amino acid found in a wide variety of foods, some of which are proteins. This condition is passed from parents to children so it is hereditary, the person must inherit the defective gene from both parents.
Cystinuria is caused when there is a high concentration of cystine in the urine. Normally, most cystine dissolves, enters the kidneys and returns to the bloodstream. However, people with cystinuria have the genetic defect that interferes with this process. This condition is due to a defective transport of cystine in the apical membrane of the intestinal epithelium and proximal renal tubule. The result is an absence of cystine reabsorption in the renal proximal tubule producing an excess of cystine in urine and with the consequent formation of kidney stones. Cystine stones are very difficult to remove by lithotripsy unlike the rest of the stones. Therefore, a non-invasive therapy should be carried out to prevent the recurrence of stone formation. This therapy would be based on a high intake of liquids, alkalization of urine, and use of chelating agents. In order to preserve kidney function, a combination of these three therapeutic measures is necessary to reduce both the recurrence and the morbidity of the disease.

What is the importance of testicular self exam
Answer:
Testicular self-exam is important because it helps detect abnormalities, especially cancer. Physicians don't check the testicles as much, so it is important to self-exam more often. Testicular cancer is more likely to be found if checked monthly. Besides cancer, routine exams create a feel for the characteristics of the testicles and would be easier to detect a sudden change.
