You can see in this particular structure, there is a hydrogen bond between a hydrogen on the hydronium ion and the oxygen on the other water molecule.
Hydronium ions don’t exist in on their own, they’re required to have some way of balancing the charge that comes from the additional hydrogen ion. This balancing is typically done by the water surrounding the hydronium ion (H3O+H3O+) since water will outnumber the amount of hydronium atoms by orders of magnitude (there’s a lot more water than ions).
The hydronium ion in cold water is typically surrounded by 6 water molecules (probably oxygen towards the extra hydrogen but I can’t access the journal to confirm). There are some other structures like the one above, and another called the Eigen cation where the hydrogen is at the center of four water molecules (one is technically the hydronium). There’s also a very large structure that’s called the magic structure that has a hydronium ion surrounded by twenty water molecules (it’s called magic because it’s extra stable for its size).

The best and most correct answer among the choices provided by your question is the fourth choice or letter D "The thin membrane that closes the cavity of the middle ear from the outside changes position."
Your ears pop in airplanes because the air high above the surface of Earth is less dense than air near the surface, because air near the surface has all the air above it pushing down. Your inner ear has air trapped in it and as the atmospheric pressure changes, it causes pressure on your eardrum.

Answers
Answer:
The answer is A
Explanation:
All the the different limbs all have an upper arm bone which is the humerus and two forearm bones which are the ulna and the radius.
The limbs of Whales, horses, birds, cats, and humans provide evidence of common ancestry because they have the same basic structure. Thus, the correct option for this question is A.
What is a common ancestor?A common ancestor may be defined as an ancestral organism that is significantly shared by two or more descendent lineages. In a more simple term, an ancestor that they have in common. These ancestors follow each taxon's lineage back in time until all the lineages meet up.
A Common Ancestor is a lineage that undergoes cladogenesis, that is, branching evolution, such that more than one species can trace its ancestry back to the common ancestor or, more accurately, to multiple common ancestors.
Therefore, the limbs of Whales, horses, birds, cats, and humans provide evidence of common ancestry because they have the same basic structure. Thus, the correct option for this question is A.

Explanation:
A.
The transpiration stream that passes through a plant may follow an apoplastic route, with low resistance to flow, or a cell-to-cell route, in which cellular membranes impede water flow. However, passage of water through membranes can be facilitated by aquaporins thereby decreasing resistance. We investigated the relationship between transpiration, which can be down-regulated by abscisic acid (ABA) or by high humidity, and the osmotic water permeability (Pos) of protoplasts. By using leaf protoplasts of wild-type (wt) Arabidopsis thaliana plants and of mutants that are low in ABA (aba1) or insensitive to ABA (abi1 and abi2), we found that protoplasts from aba1 and abi mutants have very low Pos values compared with those from wt plants when the plants are grown at 45% relative humidity. High values of Pos were found 3 h after the addition of ABA to the culture medium of aba1 plants; addition of ABA to abi plants did not restore the Pos to wt levels. There was no such increase in Pos when excised leaves of aba1 plants were treated with ABA. When the transpiration stream was attenuated by growing the plants at 85% relative humidity, the Pos of protoplasts from all plants (wt and mutants) was higher. We suggest that attenuation of the transpiration stream in whole plants is required for the up-regulation of the Pos of the membranes, and that this up-regulation, which does not require ABA, is mediated by the activation of aquaporins in the plasma membrane.
B.
The influence of abscisic acid (ABA) on carbon metabolism, rate of photorespiration, and the activity of the photorespiratory enzymes ribulose bisphosphate oxygenase and glycolate oxidase in 7-day-old barley seedlings (Hordeum vulgare L. var. Alfa) was investigated. Plants treated with ABA had enhanced incorporation of labeled carbon from 14CO2 into glycolic acid, glycine, and serine, while 14C incorporation into 3-phosphoglyceric acid and sugarphosphate esters was depressed. Parallel with this effect, treated plants showed a rise in activity of RuBP oxygenase and glycolic acid oxidase. The rate of photorespiration was increased twofold by ABA treatment at molar while the CO2-compensation point increased 46% and stomatal resistance increased more than twofold over control plants.
