Answer:
Synthetic
Explanation:
Synthetic drugs are drugs that are man-made and chemically-created in a lab by modifying the molecular or chemical structure of another substance. The synthetic drug now has properties and effects that are similar to that of the substance that is being mimicked.
Various illicit drugs such as marijuana and cocaine are being synthesized to create synthetic drugs to mimic them. An example of a synthetic drug is synthetic marijuana also called Spice or K2.

Some viruses uses Lysogenic cycle to insert the viraldna into the host cell dna before it enters a lytic cycle.
The lysogenic cycle also referred to as nonvirulent infection, includes the virus integrating its genome with the genome of the host cell in order to replicate without destroying the host. An example is the structure of a bacteriophage. To reproduce, the phage should first penetrate the host cell.
The lysogenic cycle is characterized by The phage infecting a bacterium and inserting its DNA into its chromosome, enabling the phage DNA (now known as a prophage) to be replicated and transferred on alongside the cell's own DNA.
The lytic cycle includes virus reproduction by utilizing a host cell to produce more viruses, which then ruptured out of the cell. The viral genome is incorporated into the host cell genome during the lysogenic cycle, infecting it from within.

b. tundra
c. arctic
d. taiga
Answers
The correct option is D.
The Taiga biome, which is also known as the coniferous forest has been described as the largest terrestrial biome because it extends across some continents of the world. The biome typically has short summers, which can be very wet and winters, which are long and can be very cold. The majority of plants in taiga biome are conifers and these plants are described as ever green because they remain green all year round.
Chaparral is not really a biome, it's too small for that.
So it must be taiga, and it is! Taiga has temperatures raging from -30 to +30!

Answer:
The diagram of the virus is given below.
Explanation:
Virus may be defined as the simple organism that contain DNA or RNA as their genetic material, surface area is covered with protein coat. Body is divided into head, neck collar and tail fibers. Virus requires a host organism for its growth and reproduction. Virus can affect plants, animals, bacteria and microorganisms.
Viruses are very small, typically between 20 and 300 nanometers in diameter and are so small that they can only be seen with an electron microscope.
How do we explain?
Viruses are not considered to be living organisms because they do not have their own metabolism. They need to infect a host cell in order to reproduce. Once a virus infects a host cell, it takes over the cell's machinery and uses it to make more copies of itself.
Viruses can cause a wide variety of diseases, including the common cold, the flu, and AIDS. There is no cure for most viral diseases, but there are treatments that can help to relieve the symptoms.

b. turn red and orange
c. fall off
d. expand and soften
Answers
Chaparral biome is characterized by evergreen shrubs. They leaves are hard and they do not turn red or orange and eventually fall off in the autumn. So, in the winter, these shrubs leaves will remain green.
Final answer:
Chaparral shrubs retain moisture efficiently, enabling them to keep their leaves green during winter. This adaptation allows them to continue photosynthesis even in harsh winter conditions.
Explanation:
In the winter months, the leaves of chaparral shrubs actuallyremain green. The reason for this is that chaparral shrubs are adapted to dry climates and can retain moisture efficiently. This enables them to keep their leaves green year-round, despite changes in the season. In fact, the green leaves serve as an important resource for the shrubs as they continue photosynthesis even in harsh winter conditions. Therefore, the correct answer to your question is: 'In winter the leaves of chaparral shrubs remain green.'
