The correct answer is: sea stars
All animals listed above are invertebrates. One of the characteristic of invertebrates are that they are protostomes with the exception of Echinodermata (sea stars). The difference between protostomes and deuterostomes is in their embryonic development (orgin of mouth and anus).
In protostomes the mouth forms first: the oral end of the animal develops from the first developmental opening. On the other hand in deuterostomes the first opening (the blastopore) becomes the anus, and the oral end of the develops from the second opening.
Humans are also deuterostomes.
Answer:Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.
Explanation:
Photosynthesis allows autotrophs to make their own food, then in turn heterotrophs eat the autotrophs giving them food. It's like a big cycle!
The correct answer is - because it increases production of glucose, which is the plants' food.
The main reason why the plants started to move from the water towards the land was that on the land they were able to produce more glucose, and the glucose is the food that the plants produce for themselves.
The increase of glucose production on the land was possible because the plants received more sunlight. The sunlight is crucial for the process of photosynthesis, in fact this process is not possible if there isn't sunlight. By using the sunlight, as well as gases from the atmosphere, the plants manage to create their own food, glucose, and the more they produce of it, the better for them, as they can grow more, live longer, and be in better condition.
Microglia! Microglia help protect neurons from pathogens and infection. :) I highly suggest looking up the different glia online and studying their shapes features. It helps enormously! :)
Glad I could help, good luck!
