Autotrophs are organisms that make their own food. Example: plants
The path taken by pollen as it fertilizes a plant would be:
anther ---> stigma ---> style ---> ovule
The fertilization process in plant starts by pollination. Pollen grains move from the anther of a flower to the stigma of the same or different flower. On the stigma, the pollen germinates and the cells of the pollen tube grows through the style to reach the ovule.
The generative cell of the pollen travel through the pollen tube to reach the embryo sac of the ovule. The cell divides by mitosis to form sperm cells and one of the sperm cells fertilizes the egg cell to form the zygote.

Answer:
A potentiometric pH meter is used to measure the pH of a solution.
Explanation:
A pH meter is an common instrument that is used to measure the hydrogen-ion concentration in aqueous solutions , the meter indicates its acidity or alkalinity and is expressed as pH.
The pH meter measures the difference in electrical potential between a pH electrode and a reference electrode, hence the pH meter is often called a potentiometric pH meter. The difference in electrical potential is related to the pH of the solution.
Potentiometric pH meters consists of a simple electronic amplifier and a pair of electrodes, alternatively it may consist of a combination electrode, and some form of display calibrated in pH units. It usually has a glass electrode and a reference electrode, or a combination electrode. The electrodes, or probes, are inserted into the solution to be tested and pH values are read off.

Answer:6.12 x 10¹⁴ s⁻¹
Objects get their colors from reflecting only certain wavelengths when hit with white light. Light reflected from a green leaf is found to have a wavelength of 4.90 x 10⁻⁷ m. What is the frequency of the light?
