The respiratory and circulatory systems work with each other in this manner, the respiratory system will obtain oxygen then the circulatory system brings the oxygen to different parts of the body then it also takes carbon dioxide from different tissues of the body and bring carbon dioxide to lungs then the respiratory system takes carbon dioxide outside the body during exhalation
Answer:
it comes from the sun and if you don't have sunscreen you're likely to get skin cancer
<h2>C) is the correct option </h2>
Explanation:
To best convey the exact name of an organism to others in same field one should as a group, decide on an alternative that everyone understands
Names are important because they allow people throughout the world to communicate unambiguously about animal species because there are sets of international rules about how to name animals and zoologists try to avoid naming the same thing more than once, though this does sometimes happen
These naming rules mean that every scientific name is unique
The genus is the first level of taxonomic organization, in a way, because all species that are thought to be most closely related, are placed together in a genus
Scientific names are often descriptive also, suggesting something about the animal
Common names are not unique because of which it can lead to confusion about what animal is being referred to and what their relationships are to other animals
For the first question-a bicep is a large muscle in the upper arm which flexes the arm and forearm, a tricep is a large muscle at the back of the upper arm and a deltoid is a thick triangular muscle covering the shoulder joint and used for raising the arm away from the body.
The answer is: B - archaea
Explanation:
The organisms found in the subtropical forests of southern China which were acid tolerant and lacked internal organelles are the Archaea. Archaea refers to the domain of life with organisms living in extreme conditions. Because of this, the Archaea are referred to as the extremophiles.
The cells are very small, prokaryotic and are similar to bacteria in lacking a nucleus and membrane bound organelles. The cell membrane is bounded by a cell wall. They reproduce by binary fission, fragmentation or budding.
They can tolerate high temperatures and survive in hot springs, anaerobic conditions and are acid-tolerant. These acid tolearting Archaea are called the acidophiles surviving in a pH of 2 or less than 2.
They pump out protons out of the intracellular space and thus keep their cytoplasm in a neutral pH or have an acidified cytoplasm. The example are Thiobacillus acidophilus, Crenarchaeota and others.
