Answer:
you could be strict or just have consequenes like taking stuff away
Explanation:
Modelling refers to using a diagrammatic representation to present a particular event or biological activity.
The two maps shown are very good for representing/modelling mitosis.
Advantages
- They clearly lists the various steps involved in mitosis and as well included the process of cell division starting from the interphase stage (for the second diagram).
- The M phase was also clearly explained in the first diagram.
Disadvantages
- The first pictorial diagram had to labelling to depict the name of each particular phase and makes understanding difficult.
- The second diagram fails to show pictorial representation of what could have exactly happened in each stage in the process of cell division.

Answer:
In the Amazons, plants and trees are provided with more nutrients and they tend to grow much better.
Explanation:
In the African Savanas, there is mostly dry lands, so it’s harder to find a source of water for the plants and trees. But in the Amazon, there is plenty of nutrients and there are many water resources for the plants to use. So, the climates in the Amazon are much greater and keep the plants growing tall, than in the African savanna.
Hope this helps :D

Answer: The correct option is B (self-replicating molecules, such as RNA and DNA)
Explanation:
The current theory of the process of evolution makes use of present day knowledge of genes and chromosomes to explain the source of genetic variation upon which natural selection works. These genes are discrete units of inheritance which determine hereditary characteristics. All the information for the inheritable characteristics of an individual are contained in these genes.
When a cell divides, the genes duplicate themselves so that each daughter cell has an identical set of genes as the original parent cell. These genes are passed from parents to offspring in the gametes of the parents.
Gene are found in the DNA( Deoxyribonucleic acid) molecules or RNA (Ribonucleic acid) molecules. These molecules are capable of self replication due to a process called mutation. Mutations are random changes in DNA that alter genetic information and sin introduce new characteristics. They may occur
--> in body cells or
--> during gamete formation.
Thus, evolution from vesicles to true cells is through self replicating molecules through the process of mutation which is the raw material for evolution
