What is hybridization?

Hybridization is the process of breeding two individuals of different varieties, strains, or species to produce offspring with traits from both parents. This can occur naturally, through the cross-pollination of flowers or the natural mating of animals, or it can be artificially induced by humans through techniques such as selective breeding or genetic engineering.

Hybridization is often used in agriculture and horticulture to produce crops or ornamental plants with desirable traits from different varieties or species. For example, hybrid corn was developed by crossing different varieties of corn to produce plants with improved yields, disease resistance, and other beneficial traits. In animal breeding, hybridization is used to produce animals with specific characteristics, such as hybrid dogs that have traits from different purebred parent breeds.

Hybridization can also occur in nature when two different species come into contact and are able to breed. This can lead to the creation of hybrid species, which are offspring that have characteristics of both parent species. Hybridization can sometimes lead to the creation of new and unique species, but it can also cause problems, such as the introduction of invasive species or the erosion of genetic diversity.

#7 A cuckoo bird lays its eggs in a warbler bird's nest. Once hatched, the cuckoo chicks displace the warbler chicks, tricking the parent warbler into caring for them over their own young. What type of ecological interaction does the cuckoo have with the warbler?



a. Commensalism


b. Competition


c. Mutualism


d. Parasitism

Answers

Answer:

Parasitism

Explanation:

Parasitism is a kind of interaction between organisms in which only one organism gains from the interaction. Usually one organism gains at the expense of the other organism.

In this case, the cuckoo bird gains at the expense of the warbler bird. The cuckoo bird lays its eggs in the warbler bird nest and also tricks the warbler bird to care for its young at the expense of the warbler bird's young.

This is parasitism.

Answer:

Parasitism

Explanation:

This type of relationship is the brood parasitism, a clear example of the parasite-host relationship. Instead of building their own nest for their living, the cuckoo will lay their eggs in what is known as reed warbler’s nest.  This leaves the warbler to take care of the egg together with her own children. When the eggs get hatched, the chick of the cuckoo will then ejects the young of the warbler from the next, which paves way for it to get all the food that its adopted mother will provide.

what do oceanographers use echo-sounding devices to study?

Answers

Echo sounding is a type of sonar used to determine the depth of water by transmitting sound waves into water. ... Echo sounding can also refer to hydroacoustic "echo sounders" defined as active sound in water (sonar) used to study fish.

Echo-sounding device are used by the oceanographers to study the distance and depth of the water to know how fast the sound waves travel.

What is an echo-sounding device?

Echo sounding is the measure of the depths using sound waves. Echo- sounders use different frequencies of sound to find out the different things present in the seafloor. Scientists typically use echo-sounders which transmit sound at the frequency of 12 kiloHertz (kHz) to determine how far down the seafloor depth lies.

The sound waves through the device travels down through the water column until they hit the seafloor where they are reflected back up to the echo-sounder. By recording the time it takes for the sound to travel down to the seafloor level and back again, it is possible to calculate the depth of the water as we know how fast the sound travels.

It was going to be a hot day, but the boys preferred sitting outside to unpacking more boxes inside. Their mom was unpacking kitchen stuff, and the boys had grown tired of hearing her exclaim every time she unwrapped another of the teapots she hadn't seen in months. "You'd think she'd have enough teapots by now," said James. "Yeah," said Noel, "I don't get that excited about my Godzilla collection and that is way more interesting than any teapot." "And I'm sorry," said James, "but I know way too much about teapots for a boy my age." James then started listing all the things he knew about teapots. "There's the spout and the pouring angle," he began. But Noel had already tuned James out. The heat was rising and as tired as he was of his mother's teapots, he was more tired of James' complaining. Besides, there was a raggedy old dog down the street. Noel could tell, even from far away, this was a dog that belonged to no one. Its coat was matted. It had no collar. All he could see of the dog's face was its nose sticking out. Its coat was all brown, but a dirty, grayish brown, not the deep dark warm brown that made you feel safe. "And there's that teapot with the flowers. The brown one with the little dots all in a row," James continued on his rant, now listing all the teapots he had unwrapped for Mom. Noel continued ignoring James and watched the dog. It was moving slowly in their general direction. It stopped at various spots along the curb to smell things. Sometimes the smelling took a very long time. Every now and then it would sit down to scratch behind its ear. Noel wondered if it was looking for something to eat.
