Answer: Option A) 99% of that in the entire atom

Explanation:

An atom consists of three subatomic particles named protons, neutrons and electrons. The protons and neutrons are found in the nucleus of the atom, while the mass of electrons is 1/1840 (negligible).

Thus, the mass of protons and neutrons in the nucleus makes 99% of the entire atom

Which information can be determined from the chemical formula C6H12O6?; What is the correct formula for photosynthesis?; How are
3241004551 [841]

The chemical formula C6H12O6 is the chemical formula of glucose which is a monosaccharide containing an aldehyde group (-CHO) with 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms. Glucose is a product produced from photosynthesis.

The chemical molecular formula for the photosynthesis process is 6CO2+6H2O→C6H12O6+6O2. The synthesis process is a reaction that occurs in plants to produce food to be used as energy for cells. The process of photosynthesis requires materials in the form of air which is represented by H2O and carbon dioxide which is represented by the formula CO2 in the chemical formula of the photosynthesis process. The products of photosynthesis are glucose which is represented by C6H12O6 and oxygen which is represented by O2 in the chemical formula.

Some people often refer to the chemical formula of photosynthesis as CO2+H2O→C6H12O6+O2, this formula is an unbalanced equation. Because the auction will produce glucose with the chemical formula C6H12O6 having 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms, then should the chemical formula carbon dioxide H2O and water O2 also have a total of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.

Leaves curving towards sunlight are examples of _____.
aleksklad [387]


The correct answer is phototrophism.

Phototrophism is said to be the growth of a plant toward a source of light.

It is response to the stimulus of  light and is seen when a plant bends towards the direction that light is coming from. Response by plants to a stimulus is called tropism. The  word or prefix "photo" means or refers to light. Therefore phototropism simply means response to light.

Phototropism can be especially evident in the jungle where the jungle floor gets very little light. If a tall tree falls to the ground, it leaves a gap in the canopy through which sunlight streams to the ground. Many jungle plants growing on the ground will bend towards the  gap  and rapidly grow towards the source of  light.
