<span>The answer is letter c. Artificial erosion causes a loss of fertile soil. Natural erosion is considered to be a beneficial process, since it helps create more fertile soil. While an Artificial Erosion causes fertile loss on the soil, artificial erosions causes drastic changes to the whole soil, that causes infertile soil.</span>
Answer:
Genetics has a role in the development of neurodegenerative diseases like Parkinson's disease
, ALS and Alzheimer's disease.
Explanation:
Neurodegenerative diseases are disorders caused by the progressive loss of structure or function of neurons (degeneration) in the peripheral nervous system or the central nervous system. The neurodegenerative diseases like Parkinson's disease
, ALS and Alzheimer's disease are caused by various genetic and environmental factors.
Amyotrophic lateral sclerosis (ALS)
is a neurodegenerative disease in which the motor neurons degenerate and the muscles begin to waste away as they no longer receive signals from the brain. It is characterized by stiff muscles, muscle twitching, progressive muscle weakness from muscle wasting where most patients are unable to walk or use their arms and eventually develop difficulty in speaking, swallowing and breathing. The genetic factors related to ALS include altered RNA metabolism, presence of protein aggregates in motor neurons due to gene mutations etc.
Alzheimer’s disease (AD) begins with short term memory loss and is characterized behaviorally by progressive decline in cognitive function resulting in dementia. The characteristics of this disease includes buildup of misfolded tau protein, associated neurofibrillary tangles, and amyloid-beta senile plaques in the brain. Several genetic factors contributing to AD include mutations to the amyloid precursor protein (APP) and presenilins 1 and 2 genes.
Parkinson's disease (PD) is a degenerative disorder that mainly affects the motor system and the symptoms are shaking, rigidity, slowness of movement, difficulty with walking and dementia. Genetic factors include mutations to the alpha-synuclein gene.
Interphase i think let me know if its right
Danish scientist Hans Christian Gram devised a method to differentiate two types of bacteria based on the structural differences in their cell walls. In his test, bacteria that retain the crystal violet dye do so because of a thick layer of peptidoglycan and are called Gram-positive bacteria. In contrast, Gram-negative bacteria do not retain the violet dye and are colored red or pink. Compared with Gram-positive bacteria, Gram-negative bacteria are more resistant against antibodies because of their impenetrable cell wall. These bacteria have a wide variety of applications ranging from medical treatment to industrial use and Swiss cheese production.

<h3>What is anatomy?</h3>
Anatomy is a science that deals with the structure of the body of living organisms. We know that the structure of the body of an organism holds a lot of connection to the evolutionary history of the organism hence it can be used to predict the behavior of an organism such as the kind of things that organism may feed on.
When you are able to compare the jaw structure of all the organisms, then you could clearly see the relationship between the given jaw structure and that of other species hence what the specie eats can be obtained by extrapolation.
