Identify ways in which the environment can both nurture and thwart ( and hinder) mental ability.

Hi

Here we will review some environmental factors that can affect mental ability of organisms either positively or negatively.

1)Poor Parental Care

If there will be less parental care towards the child care at the time of pregnancy like a mother who is smoking or drinking, a mother who is malnourished or who is taking certain drugs. It will pose the health of child at serious stake and the child will have poor IQ. The situation is vice versa when the mother will be healthy it will effect on child by improving his cognitive abilities and IQ level.

2) Malnutrition  

Research and different studies have shown that malnourishment pose hazardous risks on the mental development of a child. A diet that lacks important minerals and nutrients like Calcium and phosphorus can badly affect the child’s mental health. It is also reported that well-nourished children can have an IQ that is 20 points higher than a child who is malnourished.

3) Healthy environment containing fewer toxins

It has been reported that if a person is living in a healthy environment with less pollutants and toxic elements around, he /she has better chances to have more peace of mind and healthy mind. This is because a polluted environment is a source of several toxins like dust, lead paints and lead pipes that can severely damage the brain and neurological system.

4) Stressful family environment

Latest studies suggest that the family system and environment also affects the mental behavior of a child. For example, if a child comes from a family that are living happily with each other and appreciate each other’s existence, there are chances that the child will have healthy brain because of all the positive thoughts and brought up. However, a child from broken family or a family that practices domestic violence is more likely to have less intellect and brain health.

Hope it help!

question#1

ans:

cell is the basic unit of organization of all living things. cells are often called the building block of life and it is the smallest unit of life. the study of cell is called cell biology. cell consists of cytoplasm enclosed within membrane, which contain bio-molecules such as proteins and nucleic acid.

two third of cell is water, which means that two-third of your whole body is water. the rest is the mixture of molecules, mainly proteins, lipids and carbohydrates.

question#2

ans:

organ:

an organ is a group of tissues specialized to form a functional unit. an example is the heart in animals.

organ system:

an organ system is a group of several organs whose functions are synchronized to release an effective action in a living organism. an example is digestive system.

question#3

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#4

question#5

our body works because of the interactions that happen between organs and organ systems.  

for example:  

the heart to regulate blood flow throughout the body. the blood carries oxygen and nutrients to the cells and carries carbon dioxide and waste away from the cells. body systems work together in maintaining a constant internal environment. when this balance is disrupted, the body systems may not function properly, and human health can suffer.   you start to feel bad.
