Correct Answer: C) a tissue

Explanation

The question is asking about a group of similar cells that work together to perform the same function. The options are enzyme, organ, tissue, and organelle. The correct answer is option C, a tissue. A tissue is a group of similar cells that work together to perform a specific function. For example, muscle tissue is made up of muscle cells that work together to contract and produce movement. Another example is nerve tissue, which is made up of nerve cells that work together to transmit messages throughout the body. Enzymes, on the other hand, are proteins that speed up chemical reactions in the body. They are not made up of cells and do not perform the same function as tissues. An organ is a structure in the body made up of different tissues that work together to perform a specific function. For example, the heart is an organ made up of muscle tissue, nerve tissue, and connective tissue that work together to pump blood throughout the body. An organelle is a specialized structure within a cell that performs a specific function. Examples of organelles include the mitochondria, which produce energy for the cell, and the nucleus, which contains the cell's genetic material. So, in summary, a group of similar cells that work together to perform the same function is called a tissue.

Correct Answer: B) Hawks

Explanation

This question is asking about the food chain consisting of grasses, grasshoppers, lizards, snakes, and hawks. The food chain represents the transfer of energy and nutrients from one organism to another. In this food chain, grasses are eaten by grasshoppers, which are eaten by lizards, which are eaten by snakes, which are eaten by hawks. The question is asking which organism is the least in number in this food chain. The answer is option B, hawks. This is because as we move up the food chain, the number of organisms decreases. There are generally fewer predators at the top of the food chain because they require a large amount of prey to sustain themselves. It's important to note that the food chain is not always a straight line from one organism to another. It can be more complex and involve multiple organisms at each level. Also, the food chain can be affected by various factors such as human activities, environmental changes, and natural disasters. To learn more about food chains and their importance in ecosystems, please see the relevant sections of your recommended textbooks.
