5.Do the differentiated teeth of the dolphin have specialized functions like our teeth and most other mammals
Answer and Explanation:
Dolphins are homodont. This means that all their teeth are all equal. They do not differentiate between each other as the human´s teeth or other mammal´s teeth.
Dolphins have different feeding strategies according to the species. They might be suction feeders, or they might catch their prey using the jow and mandible occlusion strenth.
Dolphins that catch their prey by using their jow and mandible do not chew, so they use teeth mostly to catch their prey and manipulate them before swallowing them. This is why they do not need differentiated teeth. Because they just use them to catch and manipulate.
Those dolphin species that are suction feeders do not need teeth to catch their prey because they just suck them. Most of these species only have a few teeth, mostly in their jows. These teeth are used for fighting with other individuals. Inter- and intra-specific fights among animals of the same gender and age are very common. It is believed that as these species do not need teeth for catching their prey, they evolved loosing most of them but those needed during confrontations. This is the case of Grampus griseus, Risso´s Dolphin, that only have 5 to 7 teeth in their jows.

The percentage of monocytes is increased from the normal range. The normal range for monocytes is 2-8%, but Alexi's count is 21%. This suggests that his body is fighting an infection.
How to explain the informationMonocytes are a type of white blood cell that helps to fight infections. They do this by engulfing and destroying bacteria and other foreign invaders.
In Alexi's case, the percentage of monocytes is still elevated, suggesting that the infection is still ongoing. The type of microorganism causing Alexi's infection is not known for sure, but it is likely to be a bacteria. Bacteria are the most common cause of infections, and they are typically more difficult to fight off than viruses.
Paolo would report that his throat is sore. This is a common symptom of a viral infection. The pain is caused by inflammation of the tissues in the throat. Two signs of inflammation that would be observed in Paolo's throat are redness and swelling.
In conclusion, Alexi's increased percentage of monocytes suggests that he has a bacterial infection that has been going on for some time. Paolo's sore throat, redness, swelling, and increased body temperature are all signs of a viral infection.

The above carbohydrate (cellobiose) is properly categorized as:
A. a heteropolysaccharide sugar
B. a homopolysaccharide sugar
C. a heterodisaccharide sugar
D. a homodisaccharide sugar
E. a monosaccharide sugar
Cellobiose is properly categorized as a heterodisaccharide sugar, as it consists of two glucose units linked together through a β-1,4-glycosidic bond.
The correct answer is option C.
The above carbohydrate, cellobiose, is properly categorized as a heterodisaccharide sugar. A heterodisaccharide is a type of carbohydrate composed of two different monosaccharide units joined together by a glycosidic bond. Cellobiose consists of two glucose molecules linked together through a β-1,4-glycosidic bond.
To understand why cellobiose is classified as a heterodisaccharide, let's break down the options provided:
A. Heteropolysaccharide sugar: Heteropolysaccharides are complex carbohydrates composed of different types of monosaccharides. However, cellobiose is a disaccharide, not a polysaccharide, and it consists of two identical glucose units, making it a homodisaccharide rather than a heteropolysaccharide.
B. Homopolysaccharide sugar: Homopolysaccharides are carbohydrates made up of repeating units of the same monosaccharide. Since cellobiose is composed of two glucose units, it is not a homopolysaccharide.
C. Heterodisaccharide sugar: Heterodisaccharides are carbohydrates formed by the combination of two different monosaccharide units. In the case of cellobiose, it is formed by the linkage of two glucose units, which are the same type of monosaccharide. Therefore, cellobiose is a heterodisaccharide sugar.
D. Homodisaccharide sugar: Homodisaccharides are carbohydrates composed of two identical monosaccharide units. Since cellobiose is formed by the linkage of two glucose units, it is not a homodisaccharide.
E. Monosaccharide sugar: Monosaccharides are single sugar units and cannot be further broken down into simpler sugars. Cellobiose is a disaccharide, consisting of two glucose molecules, and is therefore not classified as a monosaccharide.
Therefore, the carbohydrate (cellobiose) is properly categorized a: C. a heterodisaccharide sugar

Why can’t a purine hydrogen bond with another purine within the sugar phosphate backbone of DNA? State your reason with all the details that are required to answer the question for full credit.
Answer:
due to the structural-binding properties of the nitrogen bases
Explanation:
Adenine and guanine are purines (two-carbon nitrogen ring bases) that pair with thymine and cytosine pyrimidine nitrogen bases (one-carbon nitrogen ring bases), respectively. These specific base-pair rules are due to their hydrogen bonds (i.e., van der Waals forces), which stabilize the structure of the DNA helix. Cytosine and guanine have three sites to form hydrogen bonds to each other, while adenine and thymine have only two sites. The specific interactions between purines and pyrimidines are critical for proper bonding and attachment to the sugar-phosphate DNA backbone (i.e., for the formation of the DNA double-helical arrangement).
Which of these decreases as greenhouse gas pollution increases?
A. Rate of ice-sheet melting
B. Ocean salinity
C. Ocean surface temperature
D. Sea levels
The climate-changing gases present in the atmosphere are greenhouse gases. An increase in greenhouse gas decreases the salinity of the oceans and sea. Thus, option B is correct.
What are greenhouse gases?Greenhouse gases are the major factor contributing to global warming and climate change. They are present in the atmosphere and have increased with a rise in the level of pollution.
The greenhouse gases have an inverse effect on the salinity or the thermohaline circulation. The increased temperature affects the glaciers and results in the melting of the ice caps thereby increasing the water level and surface temperature.
The increased water level and temperature increase the evaporation rate and elimination along with the circulation rate of the water from the poles and equator resulting in decreased salinity.
Therefore, the greenhouse gases decrease salinity.
