Which of the following is not a function of a vertebrate’s endoskeleton?
a.) Increase speed of digestion
b.) Protect major organs
c.) Offer support and structure
d.) Connect with muscles to create movement
Increase speed of digestion is not a function of a vertebrate’s endoskeleton. So, the correct option is (A).
What is Endoskeleton?
The rigid part which provides internal support of the structure is called endoskeleton which develops from endoderm and is called a living structure. Some examples of endoskeleton are cartilage, bone etc. The hard part that is on the outside of the body that protects the soft tissues and muscles is called the exoskeleton.
Vertebrates are animals that have a backbone and an endoskeleton which is a skeleton inside their body while invertebrates are animals that do not have a backbone. Invertebrates may have a skeleton on the outside of their body called an exoskeleton, while some invertebrates have no skeleton at all.
It protects major organs, offer support to the structure, connect the muscles to create movement.
Thus, Increase speed of digestion is not a function of a vertebrate’s endoskeleton. So, the correct option is (A).

Name three reasons why the atmosphere is important to life on earth and explain your reasoning.
The atmosphere ensures that all living things can carry out daily processes that are vital to survival, such as breathing. Photosynthesis, for example, could not be possible without an atmosphere, because all of the gasses in our atmosphere stay there due to Earth's gravity.
The atmosphere is vital because it plays a role in the water cycle as well, allowing rain to keep falling and giving life-giving water to organisms that need it.
Life would not be possible without an atmosphere on this planet, along with other vital things, like gravity, sunlight, and water.
