Purple sea stars are found in the pacific ocean. they prey on common mussels, suppressing the mussel population in the intertidal zone of the pacific northwest. by controlling the mussel population, sea stars enable the ecosystem to support other invertebrates. experimental data suggests that purple sea stars are a keystone species in the intertidal zone of the pacific northwest. what will most likely happen to this ecosystem if the purple sea star is permanently removed? a. invertebrates in the area will undergo rapid speciation. b. vertebrates in the area will assume the role of preying on mussels. c. mussels will dominate the area, causing a net decrease in biodiversity. d. other starfish will migrate to the area and establish themselves in the purple sea star's place.

integrated circuit (ic) is defined as a set of electronic circuits on one small flat piece of semiconductor material, normally silicon. a functional electronic circuit requires transistors, resistors, capacitors, inductors, etc., and the connections between them.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
