Some animals can hear higher frequencies than humans can. This is why animals can hear things like dog whistles, and we can't hear them. In all, animals can hear differently than humans in the way that they can hear more. Some animals can hear lower frequencies than humans can. Elephants can hear much lower frequencies than humans.
The most common element in plant tissues is Carbon. This is why plants and animals are called carbon-based life forms; because we are made predominately out of carbon.
Mesoderm is a type of tissue that arises in most animals during development. It gives rise to structures such as muscles, bones, and connective tissues.

Chimpanzees and bonobos are the animals most genetically similar to humans, sharing about 98 of our DNA.
Animals that are most similar to humans share characteristics such as complex social structures, advanced cognitive abilities, tool use, communication through language or gestures, and the ability to experience emotions.
Chimpanzees are the most similar animals to humans in terms of genetic makeup and behavior. They share about 98 of their DNA with humans and exhibit complex social behaviors, tool use, and communication skills similar to humans.
There are many tissues that are similar, but for the most part there is no one tissue that is exactly the same between humans and even chimpanzees.
Most of animals are killed by humans
tissues. Tissues are groups of cells that work together to perform specific functions in an organism. They are organized into organs, which are then part of organ systems that contribute to the overall functioning of the organism.
Animals are used because scientists want to spare humans. Most animals have similar genes to humans so animals give the same reaction humans would if the experiments were being tested on the humans. Using animals is a way to help keep the human population up and still be able to find cures for those everyday diseases.
rats and humans respond similarily to ingesting many medications/chemicals/etc, but pigs are the most physiologically similar to humans
msost animals are nasty that's how they are similar
