Answer:
Carbon dioxide, Oxygen
Explanation:
The circulatory system of our body works following two pathways -
In pulmonary pathway the deoxygenated blood is carried to the lungs while in the second pathway, known as systemic pathway, the oxygenated blood is carried to the various parts and organs of our body. Thus the completed sentence in the question will be -
Blood being pumped by the heart is circulated in two circuits. One circuit carries blood with high levels of carbon dioxide to the lungs, and the other circuit carries blood with high levels of oxygen to the body.
The correct answer is animal waste and fertilizers
Ans.
Animals are multicellular, eukaryotic organisms that belong to domain eukarya. They have cells with membrane-bound cell organelles, such as mitochondria, endoplasmic reticulum, nucleus, Golgi body, and lysosomes. In these organisms, genetic material is present inside the nucleus (known as true nucleus), which is surrounded by double-membrane system.
Thus, the correct options are:
-They contain a nucleus.
-They are eukaryotic.
-They contain membrane-bound organelles.
Because of the small fillaments.
<h2>c) option is correct </h2>
Explanation:
- Each synovial joint has a fibrous capsule surrounding the joint, which helps hold the bones together, along with the ligaments (which join bone to bone) and tendons (which join muscle to bone)
- The joint capsule is lined by the synovial membrane, which manufactures the synovial fluid
- The synovial fluid is located within the joint cavity of a synovial joint and has three primary functions: Lubrication
, nutrient distribution and shock absorption
