A few of the positive particles aimed at a gold foil.
Mutualism is a way of life in which two species that could live independently come together permanently or sporadically and each one puts something on their side for the survival of both. In nature there are many types of mutualism, for example, the spider and the toad, the narrow-billed toad is an ally of a type of tarantula that usually devours small frogs, but what, in exchange for this small amphibian to eat the parasites that affect its eggs, the arachnid allows it to live in his burrow underground and in return defends him from possible predators, like owls, throwing to them urticating hairs in their eyes.
The soda contains CO2 that is dissolved CO2 reacts with water
CO2+H2O--->H2CO3
to form carbonic acid
this is a weak acid but it gives protons to water
H2CO3+H2O-->-HCO3+H30+
pH=-lg[H3O+]
[H3O+] is the molar concentration
Therefore the acid present in the solution causes the pH to be lower than 7. It can either be the H2CO3 if it is a carbonated beverage or citric acid from lime juice.
Answer: b. Water molecules
When sunlight is absorbed by one of many pigments present in photosystem II the light energy is distributed from pigment to pigment until it reaches the reaction center of photosystem II. The electrons present in the reaction center jumps to higher energy state on receiving light energy. Each high energy electron is passed to an acceptor molecule (plastoquinone) and replaced with an electron produced by splitting of water. The splitting of water produces oxygen and electrons. The high energy electrons are transferred to electron transport chain. The energy present in these electrons creates a gradient in the thylakoid membrane of chloroplast. The gradient facilitates the flow of H⁺ ions across thylakoid membrane and which lead to the production of ATP by enzyme ATP synthase.
Therefore, water is required to produce electrons in photosystem II.

Crop is the part of the digestive
system you would see in a cross-section anterior to the gizzard. The crop is a
large dilation of the oesophagus and is located just outside the body cavity in
the neck region. The crop stores swallowed feed and water which are then moved
to the rest of the digestive tract while the gizzard is located after the
proventriculus behind the left lobe of the liver. The gizzard contains hard
objects that help in the disintegration of food.
