What is blood vessel in humans body?​
OlgaM077 [116]

Answer:

Blood vessel, a vessel in the human or animal body in which blood circulates. The vessels that carry blood away from the heart are called arteries, and their very small branches are arterioles. Very small branches that collect the blood from the various organs and parts are called venules, and they unite to form veins, which return the blood to the heart. Capillaries are minute thin-walled vessels that connect the arterioles and venules; it is through the capillaries that nutrients and wastes are exchanged between the blood and body tissues.

Which method involves breeding animals in a controlled environment? a. inbreeding b. captive breeding c. outbreeding d. crossbre
zhannawk [14.2K]

The answer is captive breeding.

Captive breeding involves breeding animals in a controlled environment.

What is captive breeding?

The technique of keeping plants or animals in confined spaces, such as zoos, botanical gardens, and other conservation facilities, is known as captive breeding, sometimes known as captive propagation. It is occasionally used to support species that are under threat from human activities including climate change, habitat loss, fragmentation, excessive fishing or hunting, pollution, predation, illness, and parasitism.

Relatively little is known about the circumstances necessary for effective breeding in many species. The success of a captive breeding program may depend on knowledge of a species' reproductive biology. Captive breeding programs have the potential to preserve some species from extinction, but they depend on a variety of criteria, including genetic, ecological, behavioral, and ethical considerations.

How does this sentence violate the principles of objectivity in writing a summary?
Mnenie [13.5K]
You didn't provide the sentence that is relevant in this case, however, generally if you would like to be objective in a sentence, you shouldn't include possible issues such as subjective thoughts, judgments, and similar things which have a negative impact on objectivity (and in reality destroy any remaining objectivity in a sentence).
