Answer the following question given this paragraph: Inside the atom, two types of subatomic particles have electric charge: electrons, which have an electric charge of -1, and protons, which have an opposite but equal electric charge of +1. The model of an atom in the Figure below shows both types of charged particles. Protons are found inside the nucleus at the center of the atom, and they give the nucleus a positive charge. (There are also neutrons in the nucleus, but they have no electric charge. ) Negative electrons stay in the area surrounding the positive nucleus because of the electromagnetic force of attraction between them. Q: What kind of charges do protons give the nucleus? Choices: - negative - dynamic - neutral - positive A:
(Answer)
positive
Ques: Answer the following question given this paragraph: The survival of every ecosystem is dependent on the producers. Without producers capturing the energy from the sun and turning it into glucose, an ecosystem could not exist. On land, plants are the dominant producers. Phytoplankton , tiny photosynthetic organisms, are the most common producers in the oceans and lakes. Algae, which is the green layer you might see floating on a pond, are an example of phytoplankton. Q: Where do producers in an ecosystem generally get their energy from? Choices: - predators - chlorophyll - consumers - the sun A:
Ans: the sun

Answer the following question given this paragraph: Biological organization exists at all levels in organisms. It can be seen at the smallest level, in the molecules that make up such compounds as DNA and proteins, to the largest level, in an organism such as a blue whale, the largest mammal on Earth. Similarly, single celled prokaryotes and eukaryotes show order in the way their cells are arranged. Single-celled organisms such as an amoeba are free-floating and independent-living. Their single-celled "bodies" are able to carry out all the processes of life such as metabolism and respiration without help from other cells. Q: What is the largest mammal on earth? Choices: - tiger shark - water buffalo - giraffe - blue whale A:
(A).
blue whale

Ques:Answer the following question given this paragraph: Not all wetlands are alike, as you can see from Figure below . Wetlands vary in how wet they are and how much of the year they are soaked. Wetlands also vary in the kinds of plants that live in them. This depends mostly on the climate where the wetland is found. Types of wetlands include marshes, swamps, and bogs. Q: Marshes, swamps, and bogs are types of what? Choices: - grasslands - rivers - ponds - wetlands A:

Ans:
wetlands
