which best vestigial structures
Answers
Answer:
Probably D
Explanation:
A "vestigial structure" or "vestigial organ" is an anatomical feature or behavior that no longer seems to have a purpose in the current form
•Vestigial structures are small structures that are not present in close relatives. Vestigial structures have not yet been identified in humans, so that means they really do nothing for us which makes them useless.

Name at least two extinct species that share a close evolutionary relationship with humpback whales.
Explain the similarities and differences that exist between these species and humpback whales.
Is the fossil record complete for humpback whales? Explain your answer.
Answers
The two extinct species that share a close evolutionary relationship with humpback whales include dorudon and basilosaurus.
The similarities between these species and humpback whales include the fact that they had tailfins and their elbow joints were able to lock and this allowed the forelimb to have better control and resist the oncoming flow of water as the animal propelled itself forward.
It should also be noted that the hindlimbs of these animals were almost nonexistent and they were so tiny that many scientists think they served no effective function and may have even been internal to the body wall.
The fossil record shows whales' history from the extinct species that lived on land to cetaceans.

Come up with another myth about the classification of organisms. Then, give two to three reasons why the myth is untrue. Use complete sentences and support your answer with
evidence, using your own words.
Answers
Answer:
Myth: A dead organism is the same as a nonliving thing in science.
Fact: According to science when an organism dies it not different from a non-living thing
Evidence: Non-living things are fundamentally different than living organisms mainly because of the differences in their chemical and biological structures. Living things are made of biomolecules, complex polymers like lipids, proteins, and polysaccharides based on carbon and non-living things are usually made of minerals and other inorganic compounds. So, even if an organism is dead, we can determine that it was a living thing by analyzing its chemical structure.
Myth: The Linnaeus system of classification will always stay the same.
Fact: Carl Linnaeus, a Swedish scientist from the 18th century came up with the perfect classification system that is used up to this day unchanged.
Evidence: Although this system is still widely used to classify living organisms, it has gone through some changes. Linnaeus considered kingdoms to be the utmost level of classification, but biologists today recognize a level above kingdoms, the level of domains. Some scientists also argue that classifying organisms into kingdoms should be abandoned, because not all organisms traditionally divided into kingdoms have the same origin.
Myth: Tigers and goldfish are not related.
Fact: Tiger is a top predator in the jungles of Asia and the goldfish is a small species of fish selectively bred in China and they are not at all related.
Evidence: All living things have the same way of transferring genetic information, trough the DNA molecule. Genetic analyses showed that the last common ancestor (LUCA) of all organisms on Earth has lived 3,5 billion years ago. After that, all living things diverged into separate groups. Tigers and goldfish both are animals and have a common ancestor. Tigers may be in a close relationship with other big cats like lions and cheetahs, but they all have a common ancestor with the goldfish since all vertebrates have a common ancestor that was an ancient fish species.Myth: An organism's kingdom only describes physical characteristics.
Fact: It is commonly believed that organisms are classified into kingdoms only based on their physical characteristics.
Evidence: Before the rise of molecular biology and genetics, this may have been true, but with new scientific methods and techniques, evolutionary relationships and genetic similarities are also taken into consideration when classifying an organism.
Myth: Mammals and plants don't belong in the same domain.
Fact: Mammals, being a group of animals do not belong in the same domain as plants. Evidence: All living organisms are divided into three domains: Bacteria, Archaea and Eukarya. All of the organisms that possess a eukaryotic cell, plants, animals, protists, and fungi are in the Eukarya domain. Therefore, mammals and plants belong to the same domain, the Eukarya domain.
Your myth: Humans are not animals.
Fact: Human beings are not at all related to other species and are completely different than animals.
Evidence: Although humans possess some unique features not found in other species, we are very closely related to apes, and broadly to primates, other mammals, animals, and organisms. The chimpanzee is our closest relative, and we share up to 98% of DNA sequence with them. It is estimated that our common ancestor lived around 6 million years ago.

How Antibiotic Resistance Happens
Antibiotic resistance is a naturally occurring process. However, increases in antibiotic resistance are driven by a combination of germs exposed to antibiotics, and the spread of those germs and their resistance mechanisms.

Answers
Answer:
In the book I read, I learned about dolphins. The title is "Whales Dolphins and Porpoises" by Mark Carwardine. I learned that when a dolphin is sick or injured, the rest of the pod will ban together to make sure their friend will get air by raising the dolphin up and down for air. I learned that if enough ban together, they can drive away a great white shark. They use echolocation to find their food which is fish, squid, shrimp, jellyfish, and octopus. Finally, I learned that each dolphin has its own name for each memebr of the pod. They comunicate with clicks, whistles, and splashes.

What distinguishes angiosperms from all other plants? Have flowers Have seeds Have a vascular system Have spores
Answers
Angiosperms are distinguished from all other plants by the presence of flowers. Therefore, option (A) is correct.
What are angiosperms?Angiosperms are flowering plants that produce seeds enclosed in an ovary. They are the most diverse group of plants, with over 300,000 species.
Flowers are reproductive structures that contain both male and female reproductive organs and are responsible for the production of seeds. Unlike other plants, which rely on wind or water for pollination, angiosperms have co-evolved with animals to ensure successful pollination of their flowers.
Angiosperms also have seeds, which are protected by a fruit, and a highly developed vascular system that allows for efficient transport of water and nutrients throughout the plant. While other plants may also have seeds and a vascular system, it is the presence of flowers that truly sets angiosperms apart. They do not rely on spores for reproduction.

O Heat will flow from the water in the glass to the copper until both reach the same temperature.
O The final temperature of the water in the glass and the copper will be 10 °C.
O The final temperature of the water in the glass and the copper will be 35 °C
Answers
Answer:
The correct answer is option B, that is, heat will flow from the water in the glass to the copper until both reach the same temperature.
Explanation:
Let us see a perfectly thermal insulation system with a glass of water at higher temperatures and a piece of copper at a lower temperature, and when both encounters each other than water will lose some of the heat and that heat will be gained by the copper. The procedure will take place until and unless both attain a similar temperature. After attaining a similar temperature, there will be no change in temperature or heat between the two. The change in heat is a function of temperature difference.

The relationship deer and rabbits have in common with the squirrels and chipmunks is that of competition and not by parasitism, mutualism and predation.
What is competition?When the two species depend on same resources both of them suffers.To avoid competition the species evolve mechanisms that can benefit both of themSuch mechanism is called 'resource partitioning', i.e., the species avoid competition by choosing different times for feeding.What is parasitism?When one species benefits and other suffers.What is mutualism?When both species benefits.Example: lichensWhat is predation?When one species benefits and other suffers.Hence, Competition explains the relation deer and rabbits have in common with the squirrels and chipmunks.
