Transmitted, vertical

A transparent specimen is viewed through a microscope using transmitted light while an opaque object requires vertical illumination.

Transmitted light is the light that passes through an object. Transmitted light microscopy is any kind of microscopy in which the light is transmitted from a source located directly across the specimen from the objective. The light is commonly passed through a condenser in order to focus it on the specimen to obtain very high illumination. After the light passes through the specimen, the image of the specimen moves through the objective lens and later to the oculars where the enlarged image is viewed.

25. Review the graph below. Blue Jays and Robins do not interbreed. Assuming that both birds live in the same habitat, what woul
kolbaska11 [484]
We do quite often have mutt birds. (the correct name for such a mutt is a hybrid. <span>They are way more common than most people think, but unless you are a birdwatcher you probably wouldn’t even spot them. People often see an odd looking birds and simply think it’s a type they haven’t seen before, when in fact it is a hybrid of two well-known species. 

Having said that, for birds to hybridized they have to be fairly closely related to start with. Robins and blue jays are no more closely related than humans are to baboons. You wouldn’t expect a human and a baboon to be able to mate and produce babies would you? So no, robins and blue jays can’t interbreed.

However there are many different species of animal that CAN interbreed and produce offspring. But the different species need to be fairly closely related, far more closely than human and baboon… or a blue jay and a robin.

For example we can interbreed horses and donkeys to produce baby mules, and we can breed cattle and buffalo, or camels and llamas. And the same is true of birds. While blue jays can’t be bred with robins in the wild we quite frequently find mutt birds.

<span> Ducks are particularly noted for forming wild mutts and many if not all north American mallards for example are of mixed species ancestry.</span>

Name two strengthening/support tissues. Explain your answer
kompoz [17]

Cartilage and bone, two key types of supporting connective tissue, assist the body to maintain its posture and protect internal organs.

The collenchyma, which is made up of living cells, the sclerenchyma, which is made up almost entirely of dead cells, and the vascular tissue, which is made up of both living and dead cells. It's in charge of transporting and dispersing water, nutrients, and assimilates.
