circulation
Cnidarians, such as jellyfish, use diffusion to transport nutrients and gases. Arthropods have an open circulatory system where blood bathes the organs directly. Fish have a closed circulatory system with a two-chambered heart, while mammals have a closed circulatory system with a four-chambered heart that efficiently circulates oxygen and nutrients to all parts of the body.
Sperm cells are produced in the testes of male mammals through a process called spermatogenesis. This process involves the division and maturation of germ cells in the seminiferous tubules of the testes.
Yes, beavers are mammals.
Beavers are mammals.
Yes, mammals can help trees in several ways. For example, as mammals move through forested areas, they can help disperse tree seeds through their droppings, promoting tree regeneration. Additionally, some mammals may engage in behaviors like digging or rubbing against trees, which can help with seed germination or create necessary disturbances for new growth.
Absorption
circulatory system
Some can be dangerous but generally mammals are scared of us.
Heart
Glucose is transported through the blood
because they are samller
Bacteroides are commonly found in the gastrointestinal tract of animals, including humans. They are an important part of the gut microbiota and play a role in digestion and nutrient absorption.
Mammals do not have feathers and generally do not lay young in eggs.
No, not to humans or mammals.
No. Generally speaking mammals are more intelligent than non-mammals
Carbohydrates are transported in mammals in the form of glucose. Glucose is carried in the blood to tissues where it is either used for energy or stored as glycogen. Transport of glucose is facilitated by specific transport proteins called glucose transporters.
No, their skeletons are generally bone.
