Sponges are similar to other animals in that they are multicellular, heterotrophic, lack cell walls and produce sperm cells. Unlike other animals, they lack true tissues and organs, and have no body symmetry.
The shapes of their bodies are adapted for maximal efficiency of water
flow through the central cavity, where it deposits nutrients, and leaves
through a hole called the osculum. Many sponges have internal skeletons of spongin and/or spicules of calcium carbonate or silicon dioxide. All sponges are sessile
aquatic animals. Although there are freshwater species, the great
majority are marine (salt water) species, ranging from tidal zones to
depths exceeding 8,800 m (5.5 mi).
Answer:
A multi carpellate ovary consists of more than one carpel and may have one or more locules. Ovary position is a useful feature in classification. An ovary attached above other floral parts is termed superior; when it lies below the attachment of other floral parts, it is inferior.
Explanation:
The key function of classical conditioning is to allow an organism to <span>learn new species-typical behaviors.
Classical conditioning refers to when two or more different stimuli are joined in order for an organism to learn something it didn't know before. The more you repeat the conditioning, the faster the organism will learn. For example, Pavlov experimented with dogs - each time they were presented with food, they would also hear a bell. So each time dogs heard the bell, they knew that they would be getting food soon.

Because soap is more basic, adding the acidic solution of lemon juice will decrease the pH value and cause it to become more acidic.
Answer:
The question refers to the classification of enzymes, which can be found in plants or in plants and animals, despite the evolutionary differences some examples in nature can be found that are mentioned below
Only enzymes are found in plants:
1. Malate synthase
2. Isocitrate lyase
In plants and animals we can see that there are:
1. succinate dehydrogenase
2. citrate synthase
3. fumarase
4. aconitasa
5. malate dehydrogenase
