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.

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.

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.
