However, if the animal encounters prey 2, it should reject it to look for a more profitable prey 1, unless the time it would take to find prey 1 is too long and costly for it to be worth it. Thus, the animal should eat prey 2 only if E 2 /h 2 > E 1 /(h 1 +S 1), where S 1 is the search time for prey 1.
Developmental psychobiology posed this question since the lack of knowledge about the precise coordination of all cells, even those not related anatomically, in space and time during the embryonic period does not allow us to understand what forces at the cellular level coordinate four very general classes of tissue deformation, namely: tissue ...
In a study conducted and published, "In total, 161 participants played a series of games focused on the “life of a plant”, and were given both a pre and post quiz to determine if the game helped them retain and/or change what they knew about scientific processes like plant cell anatomy and photosynthesis. Participants showed statistically ...
Domestication was not a single event, but a process repeated at various periods in different places. Sheep and goats were the animals that accompanied the nomads in the Middle East, while cattle and pigs were associated with more settled communities. [3] The first wild animal to be domesticated was the dog.

[161] Later philosophers examined the changing practices of eating meat in the modern age as part of a process of detachment from animals as living beings.

Generally, "hogget" and "sheep meat" are not used by consumers ...
For example, the Livestock Mandatory Reporting Act of 1999 (P.L. 106–78, Title IX) defines livestock only as cattle, swine, and sheep, while the 1988 disaster assistance legislation defined the term as "cattle, sheep, goats, swine, poultry (including egg-producing poultry), equine animals used for food or in the production of food, fish used ...
Spider wasps paralyse and eventually kill their hosts, but are considered parasitoids, not predators.. At the most basic level, predators kill and eat other organisms. However, the concept of predation is broad, defined differently in different contexts, and includes a wide variety of feeding methods; moreover, some relationships that result in the prey's death are not necessarily called pre
