Invertebrates & Blogger - 7th Grade

Explanation
An invertebrate is an animal without a backbone. This means that it lacks the vertebral column, which is a defining characteristic of vertebrates. Invertebrates include a wide range of animals such as insects, worms, and mollusks, among others. They have different types of support structures, such as exoskeletons or hydrostatic skeletons, but they do not possess a backbone like vertebrates do.

Explanation
An invertebrate usually gets its body shape by a structure called a skeleton. A skeleton provides support and protection to the soft tissues of the invertebrate's body. It helps maintain the shape and structure of the organism, allowing it to move and perform various functions. Invertebrates have different types of skeletons, such as exoskeletons or endoskeletons, depending on their evolutionary adaptations. These skeletons can be made of various materials, including chitin, calcium carbonate, or even silica, and they play a crucial role in the survival and functioning of invertebrates.

Explanation
Sponges are called filter feeders because they obtain food by filtering small particles from the water. They have specialized cells called choanocytes that create currents to bring in water and trap food particles. The water is then expelled, while the trapped food is consumed by the sponge. This method of feeding allows sponges to extract nutrients from the water and capture microscopic organisms as their source of food.

Explanation
Jellyfish have a hydrostatic skeleton because they use water to support and fill their bodies. This means that their body structure is maintained by the pressure of the fluid inside their body rather than a rigid internal or external skeleton. The water provides support and allows the jellyfish to move and change shape easily.

Explanation
Invertebrates have complex nervous systems, but they do not have a well-developed brain like vertebrates. Instead, they have a simple brain called a ganglion. A ganglion is a cluster of nerve cell bodies that helps in processing sensory information and coordinating motor responses. It acts as a control center for basic functions in invertebrates, allowing them to respond to stimuli and carry out essential behaviors.

Explanation
Google's free Blogger accounts provide users with a subdomain that ends in .blogspot.com. This means that when users create a blog on Blogger, the URL of their blog will have the format "yourblogname.blogspot.com". Therefore, the statement "All of Google's free Blogger accounts end in .blogspot.com" is true.

Explanation
The statement is false because a blogger does not use an interface that is similar to a video game. A blogger typically uses a content management system or blogging platform to create and publish their content, which is different from the interface of a video game. In a video game, the interface is designed for gameplay and interaction with the game world, whereas a blogger's interface is focused on writing, editing, and managing their blog posts and content.

Explanation
The statement accurately describes what a link is. A link is a word or set of words that can be clicked on, and upon clicking, it transfers the user to another page. Therefore, the answer "True" is correct.

Explanation
In Blogger, you are not limited to using only one type of font. You have the flexibility to choose from a wide range of fonts and customize the appearance of your blog according to your preferences. Therefore, the statement that you can only use one type of font in Blogger is incorrect.

Explanation
If you push the "save" button, it does not necessarily mean that your words will be posted on your blog for anyone on the Internet to see. The act of saving may just mean that your words are being stored on your device or in a draft folder, without being published or made public. Therefore, the statement is false.
