How increased levels of CO2 in our oceans

Biology
1 answer:
dem82 [27]3 years ago
7 0
The problem is that a vast number of marine organisms build their skeletons and shells from calcium carbonate. But calcium carbonate dissolves in acidic solutions! Many researchers have shown that when these organisms are exposed to high levels of CO2, they cannot build their shells/skeletons properly.

Other than the modern horse, what was important of the evolution of an organism?
Marat540 [252]

Answer:

Evolution is considered a way in which past generations were able to adapt to the difficulties and changes that the world around them imposed, from the need to seek food to survival in the face of different climatic and landscape changes, becoming stronger and therefore allowing the enduring and transcendence of it.

Explanation:

The importance of evolutionary studies is very large, since all organisms and their characteristics are products of evolution. It has an enormous interest applied in topics such as biodiversity conservation, medicine, agriculture, livestock, etc. Evolutionary biology is concerned with understanding the processes that have given rise to the current characteristics of organisms, and explaining why the characteristics of those organisms are what they are and not different ones.

According to the image below, which season is about to begin in the northern hemisphere?
vova2212 [387]

Answer:

winter

Explanation:

On this image, we can see the Earth being tilted away by 23.5 degrees from the Sun. This tilting puts the Northern Hemisphere in a situation where it is the one that is tilted away from the Sun, thus it will receive less sunlight, as well as less direct sunlight. That will cause lower temperatures on the Northern Hemisphere, thus the winter season will start, and it will last for around three months, at least at the mid-latitude zones. On the other side, the Southern Hemisphere is more exposed to the Sun during this tilting, so t receives more sunlight, and more direct sunlight, resulting in summer in this half of the planet.
