Note: This is an answer to the last line of your question. A classical example of animals adapting to the influence of humans on their environment is the adaption of the Peppered Moth. Here is a brief summary: The peppered moth was originally a mostly unpigmented animal (<1800). During the industrial revolution in the southern parts of the UK a lot of ...

Many insects (as well as some other animals) have documented resistance to pesticides. For example, the German cockroach (Blattella germanica) can be resistant to multiple insecticides1. In addition, some populations of this cockroach are now repelled by glucose, which leads to them avoiding traps2. References: 1: Fardisi, M., Gondhalekar, A. D., Ashbrook,...

Bighorn sheep are developing smaller horns and elephants are becoming tuskless in Africa: The horns of some bighorn sheep are getting smaller, because hunters are picking off the most impressive rams before they reach their breeding peak Elephant poaching, for example, is thought to have led to an increase in the number of tuskless animals in Africa....

Nightingales have adapted to city noises by singing louder. Given that one function of singing is finding a mate there must indeed be a high, direct selection pressure to make oneself heard. Other birds have adapted in a similar fashion, e.g. by singing in a higher pitch, or at different times.

In the terms of the question, this can be regarded as calcium hydroxide, with the carbonate being in the form of calcium carbonate. Calcium hydroxide is a stronger base (pH of aqueous solution at 1mm = 11.27) than carbonic acid is an acid (pH of aqueous solution at 1mm = 4.68), so that 1mm calcium carbonate has a pH of 9.91. (Values from Aquion) Calcium ...

I'm pretty sure It's a millipede from the Julida order, that includes 750 species distributed in the northern hemisphere. https://en.m.wikipedia.org/wiki/Julida

Depends on the species and their age. All birds have fat reserves that can keep them alive for a relatively long time. It's when fledglings are left for many hours or days that one should start worrying about their survival. The following link explains more detail on how frequently birds must be fed, even if in your case I suppose you aren't the one feeding ...

no animal smaller than 5 cm can jump higher than 1 meter. grasshoppers and locusts have wings which supposedly disqualifies them. https://www.guinnessworldrecords.com/world-records/highest-jump-by-an-insect. The immense mechanical power that would be required for any animal to jump so high with such a small size is unbelievably high which is why they have ...

Wool serves as a good insulator, meaning it doesn't allow warmth to escape the wearer easily allowing the wearer to remain warm. Furthermore, wool helps maintain a dry environment by absorbing moisture from the air (and sweat) which can also keep you cool during summer. Here's a link that talks more about this for both wool wearers and sheep: https://...

The first picture is of a Clothes Moth (Tineola bisselliella). The uniform gold colour of the wings (with shiny dust that easily comes off) is diagnostic. The second and third pictures appear to be Pantry moths. I could not find a scientific reference, so I describe my own observations below. Happy to delete this if it is not appropriate. Both species ...
