Answer:
Explanation:
Decontamination is a process of cleaning the materials to an extent to remove the contaminants from them like microorganism, chemicals, dust, dirt and radioactive substances.
The decontamination of the given material can be done for each of the following:
1) Decontamination of pillow - Sterilizer called as UVC sterilizer can be used which uses the UV light to detect and destroy the germs of bubonic plaque that is transmitted by the bite of the flea. After sterilization vaccuming of the pillow can be done to remove the dead germs.
2) Used disposable syringes- It should be placed in a sharp heavy duty plastic container like detergent or bleach bottle. The bottle must be puncture resistant.
Explanation:
An environment's biology includes both abiotic factors like atmosphere, water, soil, sunlight and temperature; and biotic factors which are living components of the ecosystem. These factors lead to a gradual change of an ecosystem over time; however, humans drastically impact the environment through over-exploitation and pollution- we disrupt normal abiotic and biotic interactions. Furthermore, human impact can lead to population die-offs and extinction events, along with food and water scarcity.
Human impact on the environment can manifest as:
- overpopulation- natural resources are over used, and habitats cannot support human communities;
- urban communities also expand by cutting down trees in deforestation- this leads to erosion and flooding;
- burning fossil fuels- this reduces air quality and adds carbon dioxide to the environment leading to global warming;
- pollution- adding contaminants to the atmosphere, waterways, soil etc.
Leaves change in the fall via a natural process; in green leaves the photosynthetic pigment, Chlorphyll a is produced in significantly lower amounts. Other pigment molecules that absorb and reflect different wavelengths exist in larger concentrations- their effect is more apparent, leading to visibly orange-red leaves.

The data you will collect is the blood phenotype.By adding serums that each contains a particular antibody such as anti-A, anti-B, or anti-D ... to see if there's an agglutination with erythrocytes' antigen and the antibodies, proving the presence of the appropriate antigen in the blood.
This will help to confirm the blood grouping if this technique is done in parallel with the plasma test ( of Simonin-Michon).
