Muscles have a bunch of nuclei because they need to use the DNA in the nuclei to make the large number of proteins that they must contain, so that they can relax and contract. What other organelle might muscles need a larger than normal number of?
Centrioles, so that muscle cells can retain a rigid structure during times of heavy stress (for example: lifting a heavy weight).
Mitochondria, so that muscle cells can quickly respond to the need to relax and contract.
Vesicles, so that muscle cells can ensure water availability if there is unusually low availability of water.
Answers
Answer:
it's the Mitochondria
Explanation:
The other organelle that might muscle needs a larger than normal number of is mitochondria, so that muscle cells can quickly respond to the need to relax and contract. The correct option is b.
What are mitochondria?Mitochondria is a cell organelle that is present in both plant and animal cells. It is not present in prokaryotic cells, as prokaryotic cells do not contain cell organelles. Besides storing ATP, it also generates energy that is generated from glucose.
Muscle cells have mitochondria to accommodate this energy demand. These organelles, often known as the “power plants” of the cell, transform nutrients into the molecule ATP, which serves as a form of energy storage.
Therefore, the correct option is b. Mitochondria, so that muscle cells can quickly respond to the need to relax and contract.

Vertebrates are complex animals, but they still share some characteristics with invertebrates. Mia volunteers at her city's aquarium for the summer. She likes observing the invertebrates. Which statement explains the pattern in the body structures of invertebrates, starting with the sponges and ending with echinoderms?
Answers
Answer: Their body structure becomes increasingly more complex.
Explanation:
In the classification of living things, all animals belongs to Kingdom Animalia. This is contains two main groups namely:
--> invertebrates and
--> Vertebrates.
The vertebrates are complex animals which are characterized with the presence of a backbone.
The invertebrates are less complex animals with no backbone. The phyla that exists in this group includes: porifera, coelenterata, platyhelminthes, nematodes,annelida, mollusca, arthropoda,echinodermata and many among others.
Their body structure becomes increasingly more complex from the phylum porifera to the phylum echinodermata. The Sponges are simple aquatic invertebrates that have ASYMMETRICAL BODIES (this makes them to lack specialised tissues that could prevent them from moving about). While the echinodermata have RADIALLY SYMMETRICAL body with body parts arranged around a central mouth and anus. They have a unique system of water canals for transport inside the body and numerous tube feet moving about.
