Answer:
(a) Symbiotic, as both benefit each other for food
Explanation:
Symbiosis is a close relationship between two species in which at least one species benefits. For the other species, the relationship may be positive, negative, or neutral. There are three basic types of symbiosis: mutualism, commensalism, and parasitism.
Mutualism is a symbiotic relationship in which both species benefit. An example of mutualism involves goby fish and shrimp. The nearly blind shrimp and the fish spend most of their time together. The shrimp maintains a burrow in the sand in which both the fish and shrimp live. When a predator comes near, the fish touches the shrimp with its tail as a warning. Then, both fish and shrimp retreat to the burrow until the predator is gone. From their relationship, the shrimp gets a warning of approaching danger. The fish gets a safe retreat and a place to lay its eggs.
Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected. One species typically uses the other for a purpose other than food. For example, mites attach themselves to larger flying insects to get a “free ride.” Hermit crabs use the shells of dead snails for homes.
Parasitism is a symbiotic relationship in which one species (the parasite) benefits while the other species (the host) is harmed. Many species of animals are parasites, at least during some stage of their life. Most species are also hosts to one or more parasites.
So. we can easily say that the relationship between them is symbiotic.
The right answer is DNA is located in the nucleus.
The genome is the whole genetic material of an organism. It contains both the coding sequences, i.e. those that encode proteins, and the non-coding sequences. In most organisms, the genome is the DNA in the cells. However, in some viruses called retroviruses (eg HIV), the genetic material is RNA.
Having two copies of the mutated genes cause sickle cell anemia, but having just one copy does not, and can actually protect against malaria - an example of how mutations are sometimes beneficial.
The majority of mutations have neither negative nor positive effects on the organism in which they occur. These mutations are called neutral mutations. Examples include silent point mutations. They are neutral because they do not change the amino acids in the proteins they encode.
Hope this helped :)
Answer: I think weather front is bascially the air density, wind, and humidity.
Explanation:
Answer:
(b) - False
Explanation:
Prochlorophyte bacteria are photosynthesizers and have the same chlorophyll found in algae and vegetables, studies claim that these bacteria are the most abundant beings on the planet, accounting for half of all photosynthesis performed in the oceans.
Prochlorophyte bacteria can be divided into <em>Prochloron</em>, <em>Prochlotrix</em> and <em>Prochlorococcus</em> genera.
However, <u>prochlorobacteria</u> are not responsible for the production of dairy products, in which the most associated bacterial genera are <em>Lactobacillus</em> and <em>Streptococcus</em>. This last statement implies that alternative b is the correct one.
