The diagram below represents a marine food web and a process that can harm the human population. each circle represents an organism and the smaller dots inside them represent a toxic substance. what is being represented and how does it harm the population? the diagram represents biological half-life, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents biomagnification, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents the process by which different organisms prey upon each other; this can impact the human population by reducing the number of organisms that do not contain the toxin. the diagram represents the way that toxins are metabolized by living organisms, with those at greater trophic levels able to metabolize more efficiently than those at lower levels. this means that those at higher tropic levels are safer for humans to consume compared to the organisms at lower trophic levels.

poison levels are being represented and it show how much poison the producer has and how much the consumer has   and damage the organisms in it, particularly in the predators at the end of the chain. this is because accumulating compounds cannot be excreted.

The dotted line shows a new potential energy diagram with a shorter activation energy hill than that in the original potential energy diagram.

Explanation:

Activation energy is the extra amount of energy required by the reactants to cross the energy barrier to get converted into products.

When a catalyst is added, it lowers down the activation energy which is shown by a dotted line. As now less energy is required,  more of reactants can cross the energy barrier and get converted to products and thus increase the rate of reaction.

A catalyst increases the rate of reaction for both exothermic and endothermic reactions.

Answer : The correct option is, diagram 1.

Explanation :

As there are four states of matter which are solid, liquid, gas and plasma.

Solid state : It is defined as the state in which the molecules are arranged in regular and repeating pattern. The molecules are closely packed that means they are arranged in symmetric manner and can not move freely from one place to another.

Liquid state : It is defined as the state in which the molecules are present in random and irregular pattern. The molecules are closely packed but they can move from one place to another.

Gaseous state : It is defined as the state in which the molecules are present in irregular pattern. The molecules are not closely packed and they can move freely from one place to another.

Plasma state : It is defined as the state in which the stars, atoms lose their electrons at high temperature. The combination of the electrons and the nuclei that result is the plasma state of matter.

The phase that occurs after a solid melts is, liquid state.

Thus,

The diagram 1 shows the liquid state.

The diagram 2 shows the gaseous state.

The diagram 3 shows the solid state.

The diagram 4 shows the plasma state.

The diagrams are shown below.

Thus,

The diagram 1 shows the liquid state.

The diagram 2 shows the gaseous state.

The diagram 3 shows the solid state.

The diagram 4 shows the plasma state.

The diagrams are shown below.

C

Explanation:

An atom consists essentially of three types of particles:

- Protons: these are contained in the nucleus, and they are positively charged

- Neutrons: this are also contained in the nucleus, but they have no electric charge

- Electrons: they orbit around the nucleus, and they have negative charge

Based on this diagram, we see that the particle labeled by C is a proton, since it is in the nucleus and it is positively charged. The particle labeled by B is a neutron, while the particle labeled by A is an electron.

the 1st answer cause there are 3 boxes shaded in for the first one out of 5 and 3 for the other one but since the 2nd one is divided into 110pieces there not equivalent
