Agricultural activities in our community makes use of livest wastes which contains ammonia that enters the air as a gas and further combines with toxic atmospheric gases.
When these gases are inhales by people in the community,it goes deep down the lungs to cause heart and pulmonary diseases.
WATER POLLUTION; This occurs when fertilizers we use for agricultural practices,sewages and waste waters finds themselves in water bodies and thus promote algae and weed growth due to the presence of nutrients in the wastes making the water unhealthy and unfit for drinking.
When this unhealthy water is consumed by the community,it causes rashes, stomach and liver diseases, respiratory problems, neurological problems and other serious health problems.
LAND AND SOIL POLLUTION; This is seen when lands are destroyed or made toxic through varying human activities like:
Application of herbicides and pesticides to the soil, and disposal of wastes improperly.
These causes varying skin problems, respiratory problems and different kinds of cancer.
NOISE POLLUTION; Social events and heavily industrial machines produces noise that causes ear problems and hearing loss for people on the community.

6) ____ Many glands such as sweat glands and salivary glands are composed of this tissue.
7) ____ protein junctions from cell to cell create a continuous sheet
8) ____ Matrix is usually abundant in this general tissue type.
Answer:
1) Epithelium lines cavities, tubes, covers body
2) Nervous tissue conducts electrical impulses
3) Muscle has contractile properties
4) Connective tissue binds and connects body parts
5) Epithelium one side of this sheet of cells is embedded in a basement membrane of extracellular "glue"
6) Epithelium. Many glands such as sweat glands and salivary glands are composed of this tissue.
7) Connective tissue provide junctions from cell to cell create a continuous sheet
8) Connective tissue. Matrix is usually abundant in this general tissue type.
Explanation:
- Epithelial tissue is made up of a group of differentiated cells whose function is to cover the external surfaces of the body, as well as the interior of the internal organs. All epithelia are firmly attached to a tissue called the basal lamina.
Additionally, epithelial cells can synthesize and secrete substances, as occurs with glandular or mucosecretory epithelium.
- Connective tissue is named for its function of maintaining intercellular attachment and providing support to the various tissues and organs of the body. It is made up of collagen, elastic fibers and microfibers, in addition to fundamental substance, forming the extracellular matrix.
- Muscle tissue is formed by muscle cells, called fibers, whose main characteristic is to contract and provide movement to the body —striated muscle— and internal organs, such as smooth muscle.
The muscle fibers are grouped into fascicles that can form muscle tissue.
- Nervous tissue is formed by neurons and glia cells, which provide support and nutrition to the former. Neurons are highly specialized cells that are capable of transmitting electrical impulses through their axons and dendrites, which is the main way of functioning of the nervous system.

1. Obtain your maximum heart rate (MHR) 220 by subtracting your age from 220.
2. At what percent of maximum heart rate do you wish to train? The lower limit is 60% for training effect, and the safe upper limit is 90%.
3. Multiply Step 2 times the value of Step 1. HRR X 50% and HRR x 85%
4. A is results lower limit of target heart rate zone for training effect, and B is the safe upper limit.
Answer:1You can calculate your maximum heart rate by subtracting your age from 220. For example, if you're 45 years old, subtract 45 from 220 to get a maximum heart rate of 175. This is the average maximum number of times your heart should beat per minute during exercise.
2To be effective, exercise should be at the right intensity (about 60% to 70% of your maximum heart rate) for your age and fitness. In other words, it should not be too easy or too hard. You also must exercise long enough (20 minutes or more in your zone) to burn enough calories to lose weight.

4It is possible to exceed the upper limit of your zone without any ill effects, as long as you do not have coronary artery disease or are at risk for a heart attack. What it may do, though, is leave you with a musculoskeletal injury. Exercising above 85% of your target heart rate could bring you sore joints and muscles.

It is advisable for kids to stay at home until a treatment is already given for the lesions.

Which of the following is an EXOGENOUS source of injury to a cell?
A fever
B bacterial toxins.
C ultraviolet radiation.
D genetic malformation
Answer:
C. ultraviolet radiation.
Explanation:
Cell injury occurs when cells undergo specific changes when subjected to an internal factor or an external factor. Such change causes "illness" to the person.
Under "toxic injury," two sources may cause an injury to the cell. These are endogenous and exogenous factors. Endogenous factors originate within the body while the exogenous factors originate from the environment.
Among the choices above, it is only the ultraviolet radiation that is considered an exogenous factor because it originates from outside the person's body. Prolonged exposure to UV light damages the cells which can lead to cancer.

3- While a one-rep maximal test is an effective way to measure muscular strength, testing for muscular endurance is trickier. One way to test endurance is through exercises that ask you to lift a certain percentage of your body weight. For example, the pushup test, in which you see how many pushups you can complete in a set amount of time, is a common test of muscular endurance. Another way is to lift a fixed percentage of your one-repetition max for a certain exercise – such as measuring how many weighted squats or bench presses you can complete in 60 seconds.
