Answer:
Endocrine and Cardiovascular system
Explanation:
Excess fat intake leads to different health hazards. They affect the body and cause lipids to clog the arteries thereby preventing blood from quickly delivering oxygen to the body parts.
Excess fat intake causes fatty pancreas and decreases its function.
It also causes series of cardiovascular diseases such as heart attack; elevated cholesterol/atherosclerosis,abnormal heart rhythms, hypertension, stroke etc
Answer: The colour of A before the starch test is GREEN while after the starch test is BLUE- BLACK. The equation for photosynthesis is
6CO2 + 6H2O → C6H12O6 + 6O2.
Explanation:
PHOTOSYNTHESIS is the process by which green plants use energy from sunlight to manufacture their own food. It is a building up process since simple inorganic compounds such as carbondioxide and water are built up into large organic compounds such as glucose and OXYGEN is given off as a by product.
Oxygen given out in photosynthesis occurs in the light stage during the process of photolysis of water. This occurs when the chlorophyll traps, absorbs and captures light energy and become energised. The energised chlorophyll supplies energy which is to split molecules of water into hydrogen ion ( H+) and hydroxyl ion ( OH-). The hydroxyl ion is reconverted to water and oxygen is given out as a by product.
To show that chlorophyll is NECESSARY for photosynthesis, a variegated leaf with green and yellow patches is used for an experiment.
The green portion is marked A and the yellow portion marked B. The leaf is tested for starch using the procedure below:
--> place leaf in boiling water for half a minute to kill it.
--> decolorize leaf by placing it in hot alcohol.
--> dip decolorize leaf in hot water to soften it.
--> place leaf on tile and add iodine solution to it.
RESULT: It would be found that only the green parts contain starch as blue+black colouration is observed while yellow area is unaffected by iodine.
Answer:
Cilia
Explanation:
The element which is responsible for this is the Cilia. The form found in a human's respiratory system are known as Motile Cilia and basically act as brooms on the respiratory epithelium lining the respiratory tract. Huge waves of Motile Cilia communicate with one another in order to be able to effectively clean up all dirt and mucus from the lungs in a very organized and unified manner. This helps maintain our respiratory system running as effectively as possible.
The glands which are associated with alimentary canal are
1. Salivary glands: These produce saliva
2. Gastric glands: These secrete gastric juice
3. Intestinal glands: These secrete intestinal juice
4. Liver: It secretes bile
<span>5. Pancreas: It secretes pacreatic juice and hormone</span>
