In a natural area there's no human life, because of the protection of the fauna and the flora. In a rural area there's a little human life, in farms, camps etc.
The Earth can be divided into four main layers: the solid crust on the outside, the mantle, the outer core and the inner core. Out of them, the mantle is the thickest layer, while the crust is the thinnest layer.
hope this helps!

Matrix
Metalloproteases (MMPs) are a part of metalloproteinase enzymes family playing
an vital part in healing wounds such as physiological or pathological processes
and even in morphogenesis, reproduction, embryonic development, tissue
remodeling, arthritis, cancer and cardiovascular disease. MMPs are a product by
activated inflammatory cells (neutrophils and macrophages) and wound cells
(epithelial cells, fibroblasts and vascular endothelial cells).

MMPs (MT-MMPs) is a subgroup of MMPs which is helpful in breaking down of
extracellular material as well as in handling of biological molecules varieties. </span>
Explanation:
-increases genetic variation
-increases the fitness of a species
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.
Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell. During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:
- somatic: these only occur within certain cells, and arise from environmental factors such as UV light
- hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.
Like other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations are maintained within cells, as they form new traits called alleles, which may confer adaptations that increase the fitness of a species, along with ensuring survival by conferring a protective advantage
.
e.g. sickle cell anemia, a disease caused by a mutation, confers protection against the disease malaria.

Answer:
An enzyme refers to a kind of protein found inside a cell. The enzymes result in the chemical reactions within the body. The function to accelerate the rate of chemical reaction in order to support life. The enzymes in the body assist in performing very essential functions. These comprise eradicating toxins, building muscle, and dissociating particles of food at the time of digestion.
Enzymes are needed for performing the proper function of the digestive system. Digestive enzymes are primarily produced in the stomach, pancreas, and small intestine. However, even salivary glands generate digestive enzymes in order to dissociate the molecules of food at the time of chewing.
There are three prime kinds of digestive enzymes, which are classified on the basis of the reactions they catalyze. These are protease, amylase, and lipase.
