How is radioactive dating used to measure Earth’s age?
Answer:
The age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample. Radioactive isotopes break down in a predictable amount of time, enabling geologists to determine the age of a sample using equipment like this thermal ionization mass spectrometer
BRAINLIST What did the Magdeburg experiment demonstrate about air pressure?

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

C. Its teeth resemble modern whale teeth.
D. It was slow.
2. How can scientists determine whether an extinct animal gave birth on land or underwater?
A. Location of the hind limbs of the fetus
B. Position of the nostrils
C. Position of the head of the fetus
D. Location of the fossils
3. Fossils of Basilosaurus resemble that of modern whales because–
A. there are similarities in both anatomy and size.
B. they both have the exact same fossil coloring.
C. they lived during the same time period.
D. there are similarities in where the fossils were found.
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.

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
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.

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.
