Afina-wow [57]

The correct sequence is option (c)

All the living organisms in the world responds to the environmental conditions and that condition could be temperature, pressure, etc. The changes in the environmental conditions are first observed by the cells of the body and then by the tissues and then from tissues it gets transferred to the organ then to organ system and finally the organism responds to the change.

Mucus would most likely accumulate in the respiratory tract as a result of ciliary destruction.

Pertussis (whooping cough) is a highly contagious respiratory tract infection. A severe hacking cough is followed by the a high-pitched breath intake that sounds like "whoop" in many people. Before the vaccine, whooping cough was thought to be a childhood disease. Whooping cough now primarily affects children who have not received the full course of vaccinations, as well as teenagers and adults whose immunity has waned.

Deaths from whooping cough are uncommon, but most commonly occur in infants. That is why it is critical for pregnant women and others who will have close contact with an infant to be immunized against whooping cough. The best way to avoid pertussis is to get vaccinated. Check that you and your loved ones have received their pertussis vaccines.

Biology Photosynthesis questions

Mazyrski [523]

I cannot do the part A task...... I can do the chart (: annddd the questions below..

Glucose: Glucose is a sugar made from sunlight, with the molecular formula C6H12O6.

chloryphll: The energy that is absorbed of the photon is transferred to an electron in a process called charge separation.

ATP: is a product of the first stage of photosynthesis, and it provides energy for the second stage. energy transfer; that is, ATP is able to store and transport chemical energy within cells.

Carbon dioxide: is involved in the production of refrigeration systems, welding systems, water treatment processes

chloroplast: contains the molecule chlorophyll, which absorbs sunlight for photosynthesis.

stomoata: control the flow of gases in and out of leaves.

Thylakoid: A thylakoid is a membrane-bound compartment inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. surrounded by a lunon.

stroma; involved in the Calvin Cycle – carbon fixation, reduction and regeneration. the stroma the supportive tissue of an epithelial organ, tumor, gonad, etc.

----------------------------------

Q2: oxygenic photosynthesis and anoxygenic photosynthesis.

Q3: The general principles of anoxygenic and oxygenic photosynthesis are very similar, but oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria.

Q4: water, light and carbon dioxide, while the products are oxygen and sugars.

Q5: carbon dioxide + electron donor + light energy ==> carbohydrate + oxidized electron donor + water

CO2 + 2H2A + photons ==> [CH2O] + 2A + H2O
