The clownfish is a species of fish that lives between the stinging tentacles of sea anemones. The clownfish protects the anemone from anemone eating fish, while the anemone’s tentacles protect the clownfish from predators. The relationship between clownfish and anemone is an example of

Answers

Answer:

mutualism

Explanation:

Mutualism is a type of symbiotic relationship between two organisms in which both benefit and neither is affected negatively in any way.

Mutualism can be in the form of resource-resource when it involves an exchange of resources between the organisms, service-resource when a resource is being swapped for a service or, service to service when it involves exchange of services between the two organisms.

In this case, the clownfish offers protection service to the sea anemone while the sea anemone in turn also offers protection to the clownfish. This is a service-service mutualism.

Mutualism, both of the animals benefit from the relationship.

Why are some samples stained before viewing them?

Answers

With DNA and small samples of organisms they are often transparent or very difficult to see. When you are viewing samples with a microscope the samples are so small that they are near about invisible to see as they are about half a micrometer thick or at times even smaller. The sample is placed in paraphin or epoxy, allowed to harden and then cut by a glass or crystal knife. The samples are then stained and placed under a microscope for viewing. The staining process can produce brilliant and beautiful designs from the crosssamples of these organisms.

Some samples are transparent, or very difficult to see, therefore, they are stained in order to be seen more clearly and easier to work with.

During eye surgery, the clear layer of the eye is stained to be easily extracted, if it was clear then the surgeon might cut the eye instead of just the layer.

A goat can produce milk containing the same polymers present in the silk produced by spiders when particular genes from a spider are inserted into the goat's genome. Which of the following reasons describes why this is possible?(A) Goats and spiders share a common ancestor and, thus, produce similar protein excretions
(B) The opposite is true, too - when genes from a goat are inserted into a spider's genome, the spider produces goats' milk instead of silk.
(C) The proteins in goats' milk and spiders' silk have the same amino acid sequence
(D)The processes of transcription and translation in the cells of spiders and goats are fundamentally similar.
(E)The processes of transcription and translation in the cells of spiders and goats produce exactly the same proteins anyway.

Answers

Answer:

(D)The processes of transcription and translation in the cells of spiders and goats are fundamentally similar.

Explanation:

The genetic information present in the spider DNA can be inserted, transcribed and translated using similar machineries to that present in spiders. This produces the same protein, but the protein is likely processed and exported differently, meaning it plays different roles in each organism.

This is true for lots of scenarios, scientists frequently insert human genes into mice, and even cells in culture!

In which cell is the removal of waste occurring

Answers

Waste is removed in the kidney, which contains specialized cells called nephrons that is present in option A; waste is also released through sweat; and waste is also removed through breathing as carbon dioxide is removed, etc.

What is the waste removal process?

The removal of waste occurs in various types of cells in the body, such as the nephrons of the kidney; they are the basic functional units of the kidney, and they play a crucial role in filtering waste products from the blood and excreting them in the urine, and here, blood enters the nephron through a network of tiny blood vessels called glomeruli, and as blood flows through the glomeruli, waste products and excess fluids are filtered out. Waste is also removed through sweat and fecal materials.

Hence, waste is removed in the kidney that is present in option a, and also released through sweat, etc.
