Double fertilization occurs in Angiosperms
Answer:
Blood sugar, also known as blood glucose, comes from the food you eat. Your body creates blood sugar by digesting some food into a sugar that circulates in your bloodstream. Blood sugar is used for energy. The sugar that isn't needed to fuel your body right away gets stored in cells for later use.
Explanation:
1. The carbon-dioxide increases in atmosphere by fossil-fuels, decaying-dead, automobiles etc. and when animals or plant die they get buried and carbon content increases under the ground.
2. Greenhouse gas are those gases which trap heat in the atmosphere and maintain the temperature of the earth.
3. Diamond and graphite are solid forms of carbon.
4. Dry ice is the carbon as liquid.
5. Autotrophs make simple sugar glucose via photosynthesis and this sugar is used by heterotrophs as a substrate for respiration in the presence of oxygen.
Explanation:
When the fuels from automobiles, fossil-fuel, dead decaying organism release carbon in the atmosphere, the increase in carbon dioxide is the cause of global warming.
Greenhouse gases absorb the infrared radiations from the earth's surface and reradiate it back to the atmosphere. In short greenhouse gases allow sun's rays to pass through and maintain the earth's temperature otherwise the earth will become too cold to sustain lives.
Answer:
b. Synergistic dominance
Explanation:
The stabilizing muscles will always be <u>synergistic</u>, since only from the synergies (hence the term synergist) that arise from joint work is efficient and controlled movement possible. However, not all synergists will be stabilizers. Stabilizer will be one that, thanks to the geometric arrangement of its fibers, will have the ability to maintain alignment in the joint and stable the axis of rotation.
In the case of knee extension, we would have as stabilizers all the antagonists who, because the flexion axis is virtual and not physical, must maintain the stability of said axis. If the axle were physical, such as the wheel in a horse carriage, or on a skateboard through the bearings, the antagonistic muscles would not be necessary for this purpose, because the fixed axis would maintain the position. Since the joints of living beings do not have a fixed physical axis, it is the muscles themselves, specifically the antagonists, who must be responsible for maintaining the stability of the joint creating a virtual axis on which rotation occurs.
