Sharks and dolphins are not closely related, and their comparable body types were not inherited from a single ancestor. Their dorsal fins, flippers, and sleek bodies are the consequence of convergent evolution.
What animal is the closest cousin to dolphins?According to a team of scientists, an extinct deer-like creature the size of a fox or raccoon is more closely related to whales, dolphins, and porpoises than the hippopotamus, which is the assumption made by the public.
You might not be aware of the intimate relationship between dolphins and whales. The zoological group Cetacea is made up of mammals including whales, dolphins, and porpoises.
There are 36 species of dolphin in the Delphinidae family. Because several dolphin family members share the word whale in their common name, it can occasionally be confusing.
Even-toed ungulates like camels and cows are today's closest living cousins of dolphins, with the modest hippopotamus being the next-closest.
Therefore, Sea turtles animal is the closest cousin to dolphins.

Which of the following do we get from biodiversity?
Explanation:
Utilitarian values include the many basic needs humans obtain from biodiversity such as food, fuel, shelter, and medicine. Further, ecosystems provide crucial services such as pollination, seed dispersal, climate regulation, water purification, nutrient cycling, and control of agricultural pests.
Biodiversity supports human and societal needs, including food and nutrition security, energy, development of medicines and pharmaceuticals and freshwater, which together underpin good health. It also supports economic opportunities, and leisure activities that contribute to overall wellbeing.
Why are protists, plants, fungi, and animals classified into the same domain but into different kingdoms ?
They are the same domain because they are all Eukaryotes. They are different from each other because they are not all Multicellular.
Protists, plants, fungi, and animals are classified into the same domain but into different kingdoms, because they share certain characteristics but are completely different in other traits.
Protists, plants, fungi, and animals are eukaryotic organisms because all their cells have a cell nucleus and they have membrane-bound organelles.Protists are unicellular (single-celled) eukaryotes that generally live in water environments.Plants, fungi, and animals are multicellular and exhibit evolutionary differential features (e.g., cell wall).In conclusion, protists, plants, fungi, and animals are classified into the same domain but into different kingdoms, because they share certain characteristics but are completely different in other traits.

Jupiter's Great Red Spot is believed to be ____________.
a. a volcanic area
b. the effect of a mountain system on Jupiter's wind system
c. a zone of high ammonia concentration
d. a large rotating hurricane-like storm (cyclone)
e. none of these
The Great Red Spot, a permanent region of high pressure in Jupiter's atmosphere, is responsible for producing the largest anticyclonic storm in the Solar System. Thus, option D is correct.
What Jupiter's Great Red Spot rotating hurricane-like storm?In Jupiter's atmosphere, there is a huge, rotating storm known as the Great Red Spot. It is similar to an Earthly hurricane, but considerably bigger.
The Great Red Spot on Jupiter is larger than Earth by more than two times! Within this storm, winds can gust as high as 270 miles per hour (ca. 435 km/h).
When astronomers first focused their telescopes on Jupiter in the 17th century, they discovered a striking reddish patch on the massive planet. More than 300 years later, the Great Red Spot is still visible in Jupiter's atmosphere. It is now understood to be a big storm that is rotating like a cyclone.
Therefore, Jupiter's Great Red Spot is believed to be (a large rotating hurricane-like storm (cyclone)).

A)Ocean temperatures are relatively stable. During the day, the ocean cools the hotter air temperatures above land.
B)Ocean temperatures are relatively stable. During the night, the ocean heats the cooler air temperatures above land.
C)Ocean temperatures experience high fluctuations. During the day, the land cools the hotter air temperatures above the ocean.
D)Ocean temperatures experience high fluctuations. During the night, the land heats the cooler air temperatures above the ocean.Option 4
Answer:B
Explanation:
Ocean temperatures experience high fluctuations. During the day, the land cools the hotter air temperatures above the ocean. So, the correct option is C.
What is Ocean?Ocean is defined as a body of salt water that covers about 70.8% of the Earth's surface and contains 97% of Earth's water. It can also refer to any of the large bodies of water into which the World Ocean is conventionally divided.
The warmest oceanic region is present in the Persian Gulf, where surface water temperatures exceed 90 degrees Fahrenheit in summer. Another hot zone exists in the Red Sea, where a temperature of 132.8 degrees Fahrenheit has been recorded at a depth of about 6,500 feet.
Thus, Ocean temperatures experience high fluctuations. During the day, the land cools the hotter air temperatures above the ocean. So, the correct option is C.

A microbe from an ecosystem that exists in the same arctic region has infected the whale population. The graph below shows the new carrying capacity for the whale population.
Explain how these microbes have affected the whale population. Does this new evidence change the seal and killer whale relationship? Does this new relationship represent a sigmoid or peak phenomenon? Please provide supporting details.
Answer:
Decrease population.
Explanation:
These microbes decrease the whale population by causing infection that leads to the death of the whale. The seal and whale relationship is the relationship of prey and predator. In this relationship, seal is prey and whale is predator that feeds on seal. Whale is considered as the predator that is present at the top of the food chain which feeds on fish and squid, seals and sea birds etc.
The whale population would decrease because of the microbes and this could possibly cause too many seals, which would be an overpopulation. This relationship wouldn’t be stable until later so it would be a peak phenomena.

Which of the following changes are linked to an increase in ocean water temperature?
Answer A: An increase in metabolism in marine species and a decrease in dissolved oxygen in ocean water
Answer B: A decrease in metabolism in marine species and a decrease in dissolved oxygen in ocean water
Answer C: An increase in metabolism in marine species and an increase in dissolved oxygen in ocean water
Answer D: A decrease in metabolism in marine species and an increase in dissolved oxygen in ocean water
The changes that are linked to an increase in ocean water temperature are an increase in metabolism and a decrease in dissolved oxygen in ocean water.
What do you mean by Dissolve oxygen?Dissolve oxygen may be defined as a relative measure of the amount of oxygen that is dissolved in a given medium.
It is universally accepted that a lack of oxygen leads to a rise in temperature. The process of metabolism internally requires energy but on completion of it, the temperature may get slightly increased in the surroundings.
Therefore, the changes that are linked to an increase in ocean water temperature are an increase in metabolism and a decrease in dissolved oxygen in ocean water. So, the correct option is A.
