What else can I help you with?
Is every living thing's respiratory system the same as ours?
No, not all living things have a respiratory system like humans. Different organisms have evolved various methods to exchange gases with their environment, such as through gills, spiracles, or direct diffusion through the skin.
how has the body evolved to avoid ingesting toxins?
The body has evolved to avoid ingesting toxins by developing mechanisms such as taste aversion, which causes a dislike for foods with potential toxins, and by increasing the sensitivity of the digestive system to detect and expel harmful substances. Additionally, the liver plays a crucial role in detoxifying ingested toxins by metabolizing and eliminating them from the body.
What evolved from prokaryotes?
Eukaryotic cells evolved from prokaryotes.
What is the correct interpretation of the cladogram shown below?
Koalas evolved after trout
Why do most animals have the same kinds of organ systems?
Many animals derived from one ancestor I believe it is because most animals are the relatively the same if we are assuming that all animals evolved from the same previous life form. Most animals need the same nutrients and are composed of CHNOPS (Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, and Sulfur). The molecules of life are carbohydrates, lipids, proteins, and nucleic acids which perform the functions needed for living things to survive. This answer is kind of confusing, but... a shortened version is: Animals are composed of mostly the same substances, and the substances all need the same thing. To get the same nutrients, they have created organs to perform the functions needed to get these nutrients. *Don't quote me on this though. This is my opinion and I have nothing to back me up currently*
Does a snake have an open circulatory system?
no they dont. They have a closed circulatory system because they are so long.
Why were changed in the respiratory and circulatory systems so important to vertebrate evolution?
they improved oxygenation of tissues
What would happen if humans evolved without blood?
Humans are primates. Long before any species of primate evolved a replacement for the mammalian circulatory system, they would probably no longer be considered mammals. Actually, virtually all vertebrates possess a similar circulatory system. I think some invertebrates may get along without blood.
How come we don't gets scoushed by air pressure?
We don't get squished by air pressure because our bodies are also filled with air, so the pressure inside and outside our bodies remains balanced. Our bodies have evolved to withstand the external air pressure, and any small changes in pressure are easily managed by our respiratory and circulatory systems.
What would have happened if humans had not developed a circulatory system?
Humans didn't develop a circulatory system. Early forms of circulatory systems developed in the first animals and organisms to roam the earth. As these species evolved through speciation and genetic variation, new species came to exist that also had circulatory systems. Over time, the systems became more complex and efficient (compare the cardiopulmonary circulatory system of the human compared to the circulation of a fish). Therefore, without circulatory systems there would be no humans nor would there be life as we know it
Are small amounts of carbohydrates needed for good health?
It is better with large amounts of carbohydrates. That is what our digestive system has evolved to digest. Complex carbohydrates and not simple sugars.
Is every living thing's respiratory system the same as ours?
No, not all living things have a respiratory system like humans. Different organisms have evolved various methods to exchange gases with their environment, such as through gills, spiracles, or direct diffusion through the skin.
How does a fluke protect itself from the digestive enzymes of its hosts?
Flukes have a protective covering called a tegument that helps them evade the digestive enzymes of their hosts. The tegument acts as a barrier, preventing the enzymes from reaching the fluke's body. Additionally, some flukes have evolved mechanisms to neutralize or resist the effects of digestive enzymes.
Choose two animal organ systems and write an expository essay explaining how they show evolution change?
The respiratory and circulatory systems in vertebrates illustrate significant evolutionary changes that enhance survival in diverse environments. For instance, fish possess gills to extract oxygen from water, a system that has evolved into lungs in amphibians and mammals, allowing for efficient breathing in air. Additionally, the circulatory system has transitioned from a two-chambered heart in fish to a more complex four-chambered heart in mammals, facilitating the separation of oxygenated and deoxygenated blood. These adaptations showcase how organ systems evolve in response to environmental challenges and the demands of different lifestyles.
What does a cat's anatomy look like?
A cat has the same muscles, organs and basic bone structure like most other animals: Cats have short limbs and strong muscles for pouncing and sprinting, the circulatory and digestive system works just like other mammals', although a cat's intestinal tract is shorter than omnivores and herbivores as a cat has evolved to be very efficient at digesting meat.

What are the differences between the internal anatomy of a bird and human?
Birds have evolved to be lightweight for flight, so their bones are hollow and some organs are reduced in size. They also have a unique respiratory system with air sacs that facilitate efficient gas exchange. Additionally, birds lack a diaphragm and have a crop for storing food before digestion. Humans have a diaphragm and solid bones that support weight-bearing and movement. Our respiratory system consists of lungs with alveoli for gas exchange. Humans have a longer digestive tract with a well-developed stomach and intestines for processing food efficiently.
Why are red blood cells built to carry oxygen?
Something has to do this job, so if it wasn't red blood cells then it'd need to be something else. Unless, of course, mammals had evolved in some other way which did not have a circulatory system.
