the squid population could decrease, because the tuna population is increasing and they would eat more squid, so the dolphin population would also decrease because there would be less squid to eat, and because there are less squid the herring population would increase.
Answer:
Density = 
Explanation:
Given that,
Mass of the object, m = 1000 g
Volume of the block, V = 50 cm³
We need to find the density of the object. Density is equal to mass per unit volume.
d = m/V
So, the density of the object is .

A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). Other particles exist as well, such as alpha and beta particles (which are discussed below). The Bohr model shows the three basic subatomic particles in a simple manner.
