In examining an unknown animal species during its embryonic development, from the first development of mouth or anus, one can determine its protostome or deuterostome.

The oral end of the majority of coelomate invertebrates emerges from the blastopore, the first developmental opening, and is referred to as a protostome (Latin for "first mouth").

The oral end of the animal originates from the second aperture on the dorsal surface of the animal in the deuterostomes ("second mouth"), which include Echinodermata and the ancestors of the Chordata; the blastopore becomes the anus. The deuterostomes also exhibit indeterminate development, meaning that even if the eight cells of the embryo are split, each one would still be able to develop into a complete organism.

Aim on how does the dominant hand and non-dominant hand react to stimulus
Sergeu [11.5K]
The dominant hand will most probably be faster to react and will also react more strongly in comparison to the non-dominant hand. The reason for this is that our dominant hand tends to be better at reacting towards stimuli in comparison to our non-dominant hand.

Which of these are negative effects of global warming? Check all that apply
motikmotik

Answer:

When carbon dioxide is released into the environment, typically due to human activities and respiration in animals, it gets trapped in the atmosphere. Carbon dioxide is just one greenhouse gas, but as all of the gases accumulate in the Earth, the temperature begins to rise globally. There are many implications to this, including the melting of glaciers, bleaching of corals, and increasing necessity for air conditioning systems and ventilation. When glaciers melt, they become a part of the ocean, meaning that as more glaciers begin to thaw out, the ocean will being to grow up and out. As sea levels rise, humans and animals are left with no choice but to being moving to higher points of elevation to avoid sinking. Another consequence of glacial melting is the loss of habitat for animales in many environments. Those living in glacial areas will begin to lose the snow and ice they are built to withstand. Those living near the sea or at low points of elevation will lose their habitats as it sinks deeper into the ocean. Another problem with global warming is coral bleaching. As the ocean warms up from the rising temperature, corals will being to overheat until they become ”blaeched’ whihc essentially means that they die. Lastly, global warming will create an increasing necessity for air conditioning systems and ventilators. People who do not have access to these things or cannot afford them can risk health complications. Global  warming is a problem that cannot be ignore and the world needs to take more steps to plant trees and grasses that can photosynthesize the carbon dioxide into oxygen.
