Density.
If the density is more than that of water than it sinks.
If it is less than it floats.
Density is the amount of mass in a certain space, therefore
D = M/V
Density = mass divided by volume
Option A, E
Photosynthesis is the only biological process that takes up carbon dioxide and Photosynthesis is the only process of the carbon cycle that involves energy are statements accurately relate photosynthesis to the other processes of the carbon cycle
<h3><u>
Explanation:</u></h3>
Cellular respiration and photosynthesis are essential components of the carbon cycle. The carbon cycle is the pathways by which carbon is reclaimed in the biosphere. Carbon passes from the atmosphere to plants. In the atmosphere, carbon is appended to oxygen in a gas termed carbon dioxide.
By the medians of photosynthesis, carbon dioxide is extricated from the air to create food produced from carbon for plant germination. While cellular respiration liberates carbon dioxide into the atmosphere. Cellular respiration global aids to hold atmospheric oxygen and carbon dioxide at constant levels.
The main structural difference between LDL and HDL is their compositions. Approximately 50% of the weight of an LDL particle is cholesterol and only 25% is protein. High-density lipoprotein particles, on the other hand, consist of 20% percent cholesterol by weight and 50% protein.

Answer is D. Nitrogen fixation.
The root nodules of some plants contains Rhizobium bacteria which fixes atmospheric nitrogen into soil as Ammonia. Ammonia is converted into nitrate which is the most usable form of nitrogen in the soil. Nitrate is absorbed by the roots of the plants, from plants nitrogen reaches to animals when they eat plants.
