The correct answer is gliding joint.
<span>
A gliding joint or a plane joint is a type of synovial joint formed between bones that meet at flat or nearly flat articular surfaces. These joints allow the bones to glide past one another in any direction along the plane of the joint (twisting, turning, and sliding). </span>
Answer:
Advanced,
Decomposers, producers, consumers
Skin
Explanation:
Decomposers are primary energy source by decomposing matter, this energy is released to the soil for plants absorb it to manufacture their food through photosynthesis and these food are consumed by man who gains energy in the process.
Higher layers should have more complex features than lower layers.
Answer:
The three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart.
Explanation:
In Anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
All amphibians and reptiles except for crocodiles (having four-chambered heart) have three-chambered hearts, which typically comprises of a partially divided ventricle and two atria.
Hence, the correct statement about the three-chambered hearts of amphibians and nonbird reptiles is that, the three-chambered hearts of amphibians and nonbird reptiles are facultative, allowing variation in blood flow through the heart due to the partially divided ventricle.
I believe that the basic unit of structure and function in protists and monerans is the cell. This is because cells are basic unit of structure and function of all living things. A cell is the smallest unit of life, it is the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed.
