Phytoplankton contribute positively in the oceanic ecosystem as they are a source of food for oceanic animals. Moreover, they remove carbondioxide from the carbon cycle and utilize it for the process of photosynthesis.
Answer:
Atoms are electrically neutral as a result of having an equal amount of positive (due to the protons) and negative (due to the electrons) charges on it.
An ion generally is an electrically unbalanced atom (i.e an atom with a net charge on it)
A negative ion called an anion is produced when an atom gains an extra electron from a neighboring atom, giving it an extra negative charge. This can be produced by ionization with a radioactive radiation or simply by dissolution.
A positive ion is called a cation and it is produced when an atom loses electron to a neighboring atom. The loss of this electron causes the positive charges to outweigh the negative charges in the atom. Cations can be produced by radioactive radiation ionization of an atom or by simple dissolution.
The subatomic particle that is negative is the 'electron'.
The answer is semiconservative replication. Semiconservative meaning that half of the original molecule (one of the two strands in the double helix) is conserved in the new molecule. Replication is the process by which double stranded DNA molecule is copied to produce two identical DNA molecules. It is one of the most basic process that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each stand of existing DNA acts as a template for replication.
I believe it is D, hopefully this helps. I could be wrong but that’s what it looks like to me I only added 40 and 50
i would say it means how would organisms would react in an ecosystem. think of everyday life in your backyard perhaps. the grass uses the energy from the sun to grow. another organism, lets say a horse, eats the grass as a main source of food. lets say another grass eater lives there too-like a cow. the cow and the horse would naturally compete as they both rely on the same food source, and the same living space that is close to that food source, and so on as you move up in the food chain.
