Answer:
Trees have to adapt to their environments in order to survive them, from the shape of their leaves to the size of their branches. They also have had to adapt the shape of their crowns to the kind of climate they live in so that they may have better chances at survival.
In warm areas with lots of sunlight for instance, you will see broad cones as the tree takes advantage to get as much sunlight as it can. In colder areas where snow is abundant, trees will be conical in shape so as not to gather too much snow when it falls.
Answer:
Oil and gas production are among the main culprits of air pollution – one of the world's biggest killers according to the United Nations. When fossil fuels are burned by power plants, automobiles and industrial facilities, they generate toxic gases.
The basic unit of macro-evolution is SPECIE.
Macro-evolution refers to the theory of evolution in which changes that occur at or above the level of specie recognizes the need to better understand the patterns and processes which operate at the specie and higher levels within a hierarchical framework. Macro evolution is an evolutionary phenomenon, which can include any of the following: origination of new designs, large scale events such as extinction, broad trend and major transitions.

9. Lysogenic
Explanation:
Viruses are set of organisms classified as NON-LIVING (1) because they do not exhibit the characteristics that living things exhibit. Viruses are incapable of REPRODUCING (2) on their own, and hence, need a living host to infect in order to replicate itself.
In the structural composition of a virus, it is made up of only one type of NUCLEIC ACID (3), which can either be DNA or RNA (4). The nucleic acid is surrounded by a PROTEIN (5) coat called CAPSID (6).
There are two ways a virus can infect its host. First, it can replicate itself causing the host cell to BURST (7) or lyse in a process called LYTIC CYCLE (8). Also, the virus can remain dormant in the host cell and continually replicate with the host cell in a process called LYSOGENIC CYCLE (9).
