What is a tissue?

• A group of similar cells working together.

• A group of similar organs working together.

• A specific structure inside of an organism.

• The largest structure in a eukaryotic organism.

Answer explanation

A tissue is defined as a group of similar cells working together to perform a specific function, making the first answer choice correct. The other options refer to organs or structures, which are not accurate definitions of tissue.

Why would less oxygen make someone feel tired?

• Cells need oxygen for cellular respiration, which gives us energy

• Oxygen helps your heart pump faster to keep your blood flowing

• Oxygen goes to your lungs and gives you energy

Imagine you're a scientist like Abigail, and you're curious about how the powerhouse of the cell, the mitochondria, helps muscles work. Propose a fun hypothesis on how having lots of mitochondria in muscle cells might be like having extra batteries for your favorite toy, and design a cool experiment to test this idea.

• Hypothesize that mitochondria do not affect muscle function and observe muscle cells under stress.

• Hypothesize that more mitochondria provide more energy for contraction and measure ATP levels in muscle cells after exercise.

• Assume mitochondria have no role in energy provision and just observe natural cell death.

• Suggest that fewer mitochondria make muscles stronger and test by chemically reducing mitochondria in cells.
