The answer is sponge because all of the others have nervous tissue
The answer is plankton are floaters. Plankton and nekton are both marine aquatic organisms. The main difference between the two is that plankton tend to float and be carried by water currents while nekton are organisms that swim against the current of the water. Plankton are passive swimmers while neekton are active swimmers.
1) Generally speaking, bean plants have fewer than 100 nodules, soybean plants have several hundred, and peanut plants can have 1,000 nodules or more. Cut-open nodules from a legume displaying the reddish-pink colour of an active, healthy nodule.
2) Both of them have roots that extend far into the cup in an effort to find food to survive. Both of them have nodules.
3) The radish just occupies the cup's centre; the beans basically fill the entire space. not as many nodules as a bean plant.
what are nodules ?
On the roots of plants, particularly legumes, that collaborate with bacteria that fix nitrogen, root nodules can be seen. Capable plants develop a symbiotic association with rhizobia, a host-specific strain of bacteria, when nitrogen is scarce.

Answer: Blood to kidney excretory tubes,
- Air tubes to blood
- Blood to air tubes.
The body contains several internal exchange systems. In the kidney, metabolic wastes move from BLOOD to KIDNEY EXCRETORY TUBES. In the lung, oxygen moves from AIR TUBES to BLOOD, while carbon dioxide moves from BLOOD to AIR TUBES.
Explanation: In the kidney, metabolic wastes move from the blood to the kidney excretory tubes via the affarent arteriole into the glomerulus of the bowman's capsule from where there will be ultrafiltration of the wastes from the blood will take place followed by selective reabsorption and tubular secretion inorder for urine to be formed.
In the lungs,oxygen moves from the air tubes which are the bronchial tubes then to the alveoli where gaseous exchange takes place then the oxygen moves to the blood. While carbondioxide moves from the blood to the air tubes from where there is exchange of gases then the carbondioxide is exhaled/expired from the lungs.
