Answer:
They should ask a question, come up with a hypothesis then a testable explanation to address this question then do the experiment do the observations and see if they are right about their hypothesis
Explanation:
These are the things a scientist should do before going at it
Answer:
The correct answer is - option D. A person rubs a shoe on a rug, causing extra electrons to be transferred to the shoe.
Explanation:
Current electricity is a flow of charged particles that moves through space or any type of electrical conductor. Usually, the transfer of the electric current takes place through a wire. There are many examples of current electricity such as lightning and static electric charge.
Electric static charge is generated due to the imbalance of particles present on the surface or within the material, normally friction leads to this imbalance in particles of the material such as when a person rubs his shes on rug created an imbalance in the electrons and then transfer to the shoe.
<span>1. The bacteriophage is injecting its genetic material into the bacterial cell. The genetic material of the bacteriophage is DNA or RNA that could synthesize the protein needed for the virus replication. This will allow the virus to replicate itself inside the bacteria.
2. This type is called lytic cycle because the outcome of this cycle is the lysis(death) of the bacteria cell. In this phase, the genetic material of the virus will hijack the bacteria body and makes them replicate the virus. The lysis of bacteria allows the new virus to invade other bacteria.
3. Answer:3B
Prophage is a bacteriophage DNA that integrates with bacterial DNA. This will be found in the lysogenic cycle that was started at the 3B picture. In this cycle, the virus becomes dormant and won't replicate itself so the bacteria wouldn't lysis. The virus could become active and change into the lytic cycle if a certain condition met.</span>
Answer:
If all frogs were to die off, a valuable food source will go missing in the food chain of many animals around the world after that the number of animals that eat the frogs will die off, then the animals that eat them will go hungry, and their populations will be devastated as well.
Answer:
the ocean provides several important resources to its inhabitants
Explanation:
The majority of biomass in any ocean consists of microscopic organisms such as phytoplankton which are pivotal to aquatic ecosystems. These microorganisms are able to thrive in their habitat due to incredibly dense populations of the bacteria <em>phackingyurmom aquatica </em>present in most oceans. These bacteria provide a wide spectrum of vital nutrients. As a result many of the aforementioned microorganisms love <em>phackingyurmom</em>.
