Answer: it is slowly decreasing in speed
Explanation:
Answer:
Pulmonary artery
Explanation:
The pulmonary artery delivers oxygen poor blood to the lungs that comes from the right ventricle of the heart. The pulmonary artery is also the only artery in the body that carries unoxugenated blood. When the blood goes to the lungs, it picks up oxygen and drops off carbon dioxide to be expelled from the body. The pulmonary vein then takes the oxygen-rich blood and brings it back to the heart.
Answer:
1. Chlorophyll absorbs light
2. Water split to start electron transport chain
3. ATP produced
4. ATP used to build glucose form carbon dioxide
Explanation:
Photosynthesis is the process whereby green plants synthesize their food (glucose) in the presence of sunlight. This photosynthetic process occurs in two major stages viz: light dependent and light independent phases.
In the light dependent phase, the following occurs sequentially:
- Chlorophyll absorbs light energy from sun
- The energy is used to split water molecule in a process called PHOTOLYSIS OF WATER in order to start electron transport chain.
- The electron transport chain yields ATP and NADPH, which will be used in the next phase.
In the light independent phase, also called, CALVIN CYCLE, ATP is used to power the formation of glucose from carbon dioxide
Infection occurs when viruses, bacteria, or other microbes enter your body and begin to multiply. Disease occurs when the cells in your body are damaged as a result of infection and signs and symptoms of an illness appear. Pathogenic microbes challenge the immune system in many ways.The adaptive immune system ( antigens) reacts specifically to pathogens (germs). It is able to recognize attacking pathogens and fights against certain antigens or foreign substances. The next time a known antigen is encountered, the adaptive immune system can respond faster.
The climate in Singapore is equatorial, ie hot, humid and rainy, throughout the year. The country, which is at the same time an island, a city and a state, is actually at the Equator, in an area where there is always the opportunity for the formation of showers and thunderstorms.
Although the climate is fairly uniform, you may notice some changes in the course of the year, due to the two monsoons: the one from the north-east, occurring from November to early March, is more rainy especially in the first part, and the one from the south-west, occurring from June to September. The first period between the two monsoon, from March to early June, is the hottest and the most unpleasant of the year.
