How does animal cell structure differ from that of humans?
Animal cell structure differs from that of humans because humans have several billion cells and animals sometimes only have one. However, the basic structure of each cell is similar.
What is a structure that don't seem to have any function but may once function in an ancestor?
An appendix in humans is a structure that seems to have little function, but it may have been more important in our ancestors for digesting cellulose. Similarly, the tailbone (coccyx) in humans is a remnant of a tail that was functional in our primate ancestors for balance and mobility.
What type of structure has no clear function in some modern species?
The human appendix is an example of a structure with no clear function in some modern species. It is believed to have been important for digesting hard-to-digest plant materials in our evolutionary ancestors but has lost its function in humans over time.
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
This type of structure has no clear function in some modern species?
Vestigial structure. These are remnants of organs or anatomical features that had a purpose in ancestor species but no longer serve a clear function in modern species. Examples include the appendix in humans or the hip bones in whales.
How is an insect's exoskeleton similar to a humans?
They both perform the function of providing a rigid structure.
What type of circulatory system do African lions have?
Their circulartion system is very similar to humans (closed circulatory system)
What is function of the abomasum?
Digests protein much like monogastrics like cats dogs and humans are able to. The Abomasum is the "true stomach" of a ruminant.
How are the three points of the cell theory to explain how humans and bacteria are similar.?
*there are made of cells *there the basic unite of structure and function *there are cells produced from other cells
What the same about the dog's and human's circulatory system?
Both dogs and humans have a closed circulatory system, meaning that blood circulates within a network of vessels, including arteries, veins, and capillaries. They both rely on a heart to pump blood throughout the body, delivering oxygen and nutrients to tissues while removing waste products. Additionally, both systems involve red blood cells that carry oxygen and white blood cells that play a role in the immune response. Overall, the fundamental structure and function of the circulatory systems in dogs and humans are quite similar.
Do lions breathe like humans?
Yes, lions and humans have a similar respiratory structure.
Use the three points of the cell theory to explain how humans and bacteria are similar.?
*there are made of cells *there the basic unite of structure and function *there are cells produced from other cells

How similar are rats to humans in terms of genetic makeup and physiological characteristics?
Rats and humans share about 90 of their genetic makeup, making them genetically similar. Physiologically, rats and humans also have many similarities, such as organ structure and function, making rats valuable models for studying human diseases and treatments.
Consider the process by which bacterial populations grow What process performs a similar function in humans?
Mitosis performs a similar function in people.
Humans arms are most similar which physical structure of bird?
The wings.
What is the function of a chickens trachea?
The function of a chicken's trachea is similar to humans. It is the windpipe, and it carries air into their lungs.
