Answer:
The envelope come from the host cell membrane as the virus leaves the host cell
Explanation:
A virus is an organism that is incapable of replicating on its own without infecting a living host. A virus consists of a genetic material (DNA or RNA) , a protein coat called CAPSID, and sometimes some viruses possess an envelope, which is an outer covering or enclosure. Viruses that possess this envelope are referred to as ENVELOPED VIRUS.
The virus lacks the ability to produce any structure, hence, they gain this envelope made of phospholipid from the cell membrane of the host they infect. During the infection cycle of a virus, a process called budding enables a portion of the host's plasma membrane to cover or encapsulate the virion cells, hence, making them enveloped in the process.
Answer:
Hundreds of years ago, South American fishermen observed that every year around December or Christmas, coastal waters of the Pacific became warmer as a current flowed from north to south. This change often meant a smaller fish catch but more rainfall inland that translated to more abundant crop harvest .

Answer: The statement is false
Explanation:
Addition of concentrated sulfuric acid (H2SO4) to a beaker full of water (H2O) will release heat energy to the containing vessel due to the breakage of strong ionic bond present in the acid.
Thus, it is an evidence of a EXERGONIC REACTION (since energy is released spontaneously). So, the statement is false
Macronutrients are nutrients that provide calories or energy. Nutrients are substances needed for growth, metabolism, and for other body functions. Since “macro” means large, macronutrients are nutrients needed in large amounts. There are three macronutrients:CarbohydrateProteinFatso its not B
There are three<span> primary types of </span>antioxidants<span> found in nature. These include phytochemicals, vitamins, and enzymes.

So not C.
<span>The three micronutrients are vitamins, minerals, and water.
</span>
So not A.
And that leaves you with D.(D is the correct answer for num.1)
I think the answer would be because if there is an error in the DNA replication, it would affect one generation of cells. if the error would fall in the transcription or translation, there would only be one cell affected.
