<u>Answer:</u>
Recent evidence suggest that feathers evolved from scales and suggest that 'feathers and pycnofibers' could be homologous.
<u>Explanation:</u>
- One of the major difficult issue related to bird evolution is the evolution of feathers.
- Feathers are considered as the most 'complex integumentary structures' which are found in vertebrates.
- Evolutionary developmental biology suggests that the 'planar scale structure' is been modified for developing into feathers by 'splitting' to form web like structures.
- Scales and Feathers consist of 'two distinct form of keratin' so it was thought that 'each type was exclusive skin structure' but recent study suggests that they are developmental expressions of same skin structures.
Evolutionary theory predicted that bacterial resistance would happen. Given time, heredity and variation, any living organisms including the bacteria will evolve when a selective pressure, in this case an antibiotic is introduced. However it also gives doctors an patient some specific strategies for delaying even more widespread evolution of antibiotic resistance; these strategies include; avoid mild doses of antibiotics over long time periods, don't use antibiotics to treat viral infections, when treating bacterial infection with antibiotics, take all the pills, and also using combination of drugs to treat a bacterial infection.
Answer:
Aerobic respiration;this is the process of breaking down of glucose <u>with Oxygen</u> to generate energy as ATPs in living cells
Location- Matrix and inner membranes of mitochondria
Energy source_oxidative phosphorylation of glucose
Waste product-water( oxygen accept the final electron to form water)
.
38 ATPs from 1 glucose molecule
Explanation:
Photosynthesis; this is the process of reducing C02 with hydrogen ion, from water i<u>n the presence of sunlight , enzymes and green pigment chlorophyll</u> to form <u>glucose</u>
Location- stroma and thylakoid membranes of chloroplast
Energy source-photo-phosphorylation(sunlight)
Waste product-Oxygen
18ATPs
