Answer:
Proteins are responsible for the <u>mass </u>and <u>fat </u>of much of our bodies (and other organisms). The instructions for making protein are encoded in <u>DNA</u>. These genes provide the sequence of building blocks known as <u>nucleotides</u>. This string of amino acids then folds into different shapes. The structure of proteins determines what a <u>molecule </u>can do. Proteins contain carbon, hydrogen, oxygen, and nitrogen.

Answer:
Jean-Baptiste Lamarck
Explanation:
Jean-Baptiste Lamarck was a French biologist which developed the first theory to understand how species change (evolve) over time. This evolutionary concept was published under the name of 'Theory of the Transmutation of Species' in the early 19th century. Subsequently, Darwin published his famous and widely accepted evolutionary theory in the book 'On the Origin of Species' (1859).
The correct answers are as follows:
1. A.
There are basically two types of succession, they are primary and secondary succession. Primary succession refers to the type of succession that occurs in new and bare areas where the soil present is unable to sustain the growth of plants. An example of primary succession area is an area with sand dunes that is freshly formed. Primary succession usually occur over a long period of time. Secondary succession is a type of succession that occur on a land which was disturbed by hazardous events such as fire outbreak, flood, etc. Secondary succession occurs much faster than the primary succession.
2. D
There are two types of factors that affect any particular ecosystem, these are abiotic and biotic factors. The abiotic factors refers to non living factors such as temperature, relative humidity, rainfall, etc. while the biotic factors refer to the living factors. Looking at the options given above, one will see that only option D has living factor, which is predators. All other options have abiotic factors.
