These are plants.

The human heart is made up of multiple tissues that work together to perform a specific function. It is not just a single cell or a muscle, but rather a complex structure that has different components and functions. Therefore, the correct answer is that the human heart is an organ.

The correct answer is "it is the basic unit of living things." This answer is correct because cells are indeed the fundamental building blocks of all living organisms. They carry out essential functions and processes necessary for life, such as reproduction, growth, and metabolism. Each cell contains all the necessary components and organelles to perform these functions, making it the smallest unit capable of sustaining life on its own.

The given correct answer for this question is "Algae". This is because sea palm is a type of brown algae that is commonly found along the Pacific coast of North America. Algae are simple, photosynthetic organisms that can be found in various aquatic environments, including oceans, lakes, and rivers. They play a crucial role in marine ecosystems by providing food and habitat for many marine organisms. Sea palm, being a type of algae, fits this description and is therefore the correct answer.

A lichen is a type of organism that is formed by a symbiotic relationship between algae and fungi. The algae provide food through photosynthesis, while the fungi provide structure and protection. This combination allows lichens to survive in various environments, such as rocks, trees, and soil. Lichens are important for ecological balance and are often used as indicators of environmental health.

This is a union of many muscle cells, we call this a muscle. A muscle is made up of many muscle cells that work together to produce movement. These muscle cells are connected and organized into a tissue, which is a group of similar cells that work together to perform a specific function. Therefore, the correct answer is tissue.

Human beings use fungi to make this food. Fungi, such as yeast, are commonly used in the production of various food products, including bread, cheese, and beer. Fungi have the ability to break down complex organic compounds, making them important in the fermentation and decomposition processes involved in food production. They contribute to the flavor, texture, and preservation of these food items.

The correct answer is that human beings and other mammals share the characteristics of being born from their mother's womb, using the five senses to perceive the world, and feeding on their mother's milk during their first stage of life. This answer is supported by the information provided in the question, which states that these three characteristics are shared by human beings and other mammals.

The question says that this is NOT a characteristics of Morel. All living organisms have cells.
