D. there are similarities in where the fossils were found.

Answers

Answer:

B,C,A

Explanation:

The statement that is not true regarding Ambulocetus is it lacked hind limbs. The correct option is B.

What are Ambulocetus?

This cetacean ancestor was semiaquatic. It spent most of its time in the water but reproduced on land. Thewissen worries Ambulocetus natans resembled modern crocodiles in appearance and hunting style, consuming marine fish and maybe ambushing animals that wandered too near the water's edge.

It could have observed prey above water even while submerged thanks to the high, sideways-facing eyes on its head that resemble hippos.

2. Scientists can determine whether an extinct animal gave birth on land or underwater by the position of the head of the fetus.

3. Fossils of Basilosaurus resemble that of modern whales because there are similarities in both anatomy and size.

Therefore, the correct option is B, C, and A.

in a supermarket it is likely that the store will be divided into many categories to ensure the customer is able to find what they are looking for promptly. for example, at Walmart, you may find a clothing section, a toy section, a produce section, toiletries section, makeup section and bakery section among many others. this style of organization allows for customers to know exactly where they must go to find what they are looking for - if they would like to purchase an apple they would go to produce etc.

A.The male will be more attractive to females and predators.
B.The female is more attracted to the male and the predator.
C.The female is less likely to get eaten and less likely to reproduce.
D.The male will be less likely to attract predators and more likely to reproduce.

Explanation:

For the quiet males that intercepted the female the other males that are chirping act like a distraction for predators. So he has more chance to reproduce with the female because he is not the acual prey of whatever predator is lurking around.

Hope this helped! :D

Male crickets chirp to attract a mate, and chirping is dangerous because it can also attract predators such as birds or bats, but due to the sound, the male cricket will be less likely to attract predators and more likely to reproduce, which is in option D.

What is the significance of the mating calls?

Here, the crickets chirping sound that is a mating call represents an example of an adaptive and evolutionary strategy that has evolved in response to the challenge of attracting mates while avoiding predation, and by using it, male crickets increase their chances of survival and reproduction.

Hence, male crickets chirp to attract a mate, and chirping is dangerous because it can also attract predators such as birds or bats, but due to the sound, the male cricket will be less likely to attract predators and more likely to reproduce, which is in option D.

Which is the practice of inserting the DNA of another species into an organism's DNA so that the organism gains a new trait?
Cloning
Gel Electrophoresis
Genetic Engineering
DNA Fingerprinting

Answers

Answer:

Genetic Engineering

The practice of inserting the DNA of another species into an organism's DNA so that the organism gains a new trait is called genetic engineering. Therefore, option C is correct.

What is genetic engineering?

Genetic engineering, often known as genetic alteration, is a technique that modifies an organism's DNA using technology developed in labs.

Human insulin, human growth hormone, and the hepatitis B vaccination are examples of products produced using genetic engineering techniques. Other genetically engineered species including disease-resistant plants have also been created using these techniques.

Likewise, genes can be transferred from an animal to a plant or the opposite. GMOs, or genetically modified organisms, are another term for this. Selective breeding is not the same as the procedure used to make GE foods. Therefore, option C is correct.

describe how the abiotic factors faced in the desert differ from those in the rainforest

Answers

Answer:

Deserts and rainforests have vastly different climates and rainfall. There is more water and sunlight in a rainforest than in a desert. etc.

Explanation:

Abiotic elements in a marine ecosystem would be salinity and ocean currents. Examples could be light, water, and temperature in a terrestrial habitat.

What are the different abiotic factors

The animals are suited to live in the circumstances of the environment in both deserts and tropical rainforests.

Because of the heavy rain in the tropical rainforests and the severe heat in the deserts, neither tropical rainforests nor deserts are habitable for people.

The desert has low biodiversity since there are so few living things there. There may be no living things and hence no biodiversity in some desert regions.

The rainforest, on the other hand, contains the most diversity of any biome on Earth.

Therefore, the abiotic factors faced in the desert differ from those in the rainforest.

What is the equation of a line that is perpendicular to a line with a slope of 2 and passesthrough the point (-2, 0)? giving brainlist A Big YearBy Bob KowalskiWould you go to the ends of the earth to see a bird? What if it were a really special bird: one with beautiful feathers, an entrancing call, or a silly dance? What if seeing that one special bird would allow you to win a contest?If that contest doesn't get you on television or win you any cash prizes, would you still do it? For those who participate in the "Big Year," the honor of beating the previous record is the only reward they get or even want.A "Big Year" is a year in which a person attempts to see as many different species of birds as possible within a particular region. For most in North America who participate in a "Big Year," this region is the lower 48 American states, plus Alaska, Canada, and a couple of French islands off the Canadian coast.You may be thinking that looking at birds is silly, but just think about the numbers of the recent record holders and the commitment it takes to get these numbers. One recent "Big Year" winner managed to see 744 birds in one year, missing the record by just one bird. Big Year birders travel by train, plane, boat, car, bicycle, and of course, by foot. They can cover over 150 thousand miles to get numbers of sightings this high. They can also spend a small fortune.Just to clarify, the birds these contestants are counting are the number that they see in a particular year. You see, the contest is based on an honor system. No pictures or other evidence is required as proof of a sighting. Most birders take great pride in their reputation and their abilities to see or hear and then identify a bird. Usually, important sightings of the rare birds needed to get counts in the 700s are visited by hundreds of birders. It is pretty hard to cheat your way to a record-breaking year, but in general, few are interested in cheating.You don't have to be able to travel a continent to have a big birding experience though. Have a big month. Or a big weekend. Set a personal record, learn to identify the species that live in your part of the world, or try to learn the calls of just two species of birds. You will soon find looking at birds isn't such a strange way to spend your time.Extra! Extra! Backyard BirdingMany schools, families, and young birders across the country participate in the "Great Backyard Bird Count." While not as long as a "Big Year," the "Great Backyard Bird Count" happens every year. It depends on birders and families across the country to watch feeders and other areas in their yards and count the number of birds they see. Unlike the "Big Year," the goal is not to see who can count the most birds. Instead, participants in this event work together to help bird experts get a good idea of how birds are doing. Participants are given checklists and enter their sightings on a website. Called a "citizen-science" project, this event is open to anyone, requires no travel, and happens every year over one weekend in February.Which of the following best states the main idea of the article "A Big Year"?A)"Big Year" birders compete for honor, love, and record-setting.B)"Big Year" birders get very competitive about seeing rare birds.C)"Big Year" birders have a list of important birds to see.D)"Big Year" birders compete to see more birds than others. is y=x^8 an exponential function who is the Prime Minister of the great "India" Which of the following relations is a function?O A{(-1, - 4), (-1,0), (- 1,5), (- 1, 7), (-1,9)B.{(-2, - 4), (-1,7), (1, - 1), (1, 1), (3,9)}C.{(-4,9), (- 3, 1), (- 2, 3), (- 2, 12), (0, 6) }D.{(0, - 4), (1, - 4), (2, 4), (3, 4), (4, - 4)} O Beth walked 10 7/8 miles one week. she walked 2 1/4 fewer miles the following week.
