Explanation:

In the geological cycle, the CO2 that is in the atmosphere, dissolves in rainwater, producing H2CO3 which is an acidic solution. This facilitates the erosion of the silicate rocks by releasing the calcium and HCO3 that are later carried to the oceans where marine organisms assimilate both to build their carbonated shells. When these organisms die, the shells settle and accumulate. This bottom sediment can migrate to an area where pressure and heat partially melt the carbonates. The formation of this magma releases CO2 that escapes into the atmosphere again. It can be combined again with rainwater, completing the cycle.

In the terrestrial environment, the carbon cycle is closely linked to the respiration of living things and plant photosynthesis that removes carbon dioxide from the atmosphere and transforms it into biomass, which feeds herbivorous animals, which will also serve to carnivorous animals. After death, both animals and vegetables suffer the action of decomposers. If the decomposition of this organic matter is total, there is a release of carbonic gas, methane gas, and water, if it is partial, there is a transformation into combustible material (oil and coal). The combustible material, when burned, returns carbon to the atmosphere in the form of CO2. That is, carbon fixed by photosynthesis sooner or later returns to the atmosphere by the decomposition of dead organic matter.

What was the Cretaceous tertiary extinction attributed to what major events that triggered the extinction of dinosaurs

vfiekz [6]

Cretaceous extinction also known as Paleogene extinction was a period of time when suddenly around three quarter of the animal and plant species began to get extinct from the land. The event happened around 66 million years ago and is considered as the end of cretaceous era that lead to the beginning of Mesozoic era.

Reasons for the mass extinction:

Scientists think that a major asteroid or comet hit the surface of earth which deteriorated the earth’s environment, especially by making it difficult for plants to perform the process of photosysnthesis. This is called as Impact hypothesis and scientists think that it was the reason of extinction of so many species because they found debris of asteroid in the land.
There could also be some other reasons like climate changes,volcanic eruptions and changes in the sea level which made the environment unfavorable for the survival of living organisms.
One of the best known organism that is thought to extinct in cretaceous period was dinosaur.

Extinction of Dinosaurs:

As stated above the exact cause of dinosaur extinction can not be stated with confidence. This is because cretaceous period was the time when so many unfavorable circumstances took place like diseases, geologic events ,climate change etc.

However, the most believed theory is that some Asteroid hit the surface of earth and turned the climate very very old. Therefore, those amazing creatures were not able to survive that climate.

Because of a birth defect, Adam’s little cocker spaniel has an eyelid that is undeveloped and causes irritation and constant inf

photoshop1234 [79]

Adam looks for a natural remedy for eye infections. What herb is Adam likely to use to help his poor pup? In this case it has 3 options, mallows, chamomile and elderflower, but to better understand this issue we need to know that ......

<h3>Mallows</h3>

Mallows are spontaneous plants, the most effective and most used to treat all types of inflammation.

It can also be consumed internally, in soups and salads. The tender, aphid-free leaves, the flowers and the roots are consumed, which produce a lot of mucilage and which, for this reason, soothe irritated tissues of the stomach, intestines and skin.

Drinking a cup of infusion of mallow leaves on an empty stomach protects the mucous membranes of the stomach against the harmful effect of excessive intake of chemical drugs.

<h3>Chamomile</h3>

Chamomile, in addition to being useful for treating eye problems, is also recommended for other types of skin, mouth or digestive tract inflammation.

<h3>Elderberry flower</h3>

Elderflower (Sambucus nigra) is recommended for the relief of allergy symptoms such as

Hay fever
Rhinitis
Sinusitis
Cough
Colds
Fever or skin problems.

<h3>How to use? Make an infusion, let it cool and wash your eyes several times a day.</h3>

Never pass the cotton or the compress from one eye to the other because sometimes only one eye is inflamed and when we do that we are infecting both. Compresses or sachets of these plants over the eyes for about 15 minutes also have good results.

With this information, we came to the conclusion that these three herbs are excellent to help the puppy with his eye problem.
