Your science teacher has asked the class to make a cell city model. Which building or business in the city could represent the m

Marrrta [24]

The correct answer is <span>D) power company - produces energy.

The Mitochondria produce the energy used by the other parts of the cell - called the ATP - in a process called the Krebs cycle. The Krebs cycle produces ATP - like the energy that a power plant produces and a secondary product is </span> $CO_{23}$ , just like typical power plants also produce $CO_{23}$ while producing energy. Both in mitochondria and in power plants, the more energy is produced, the more $CO_{23}$ !

A stickleback fish will attack a fish model as long as the model has red coloring. What animal behavior idea is manifested by th

GalinKa [24]

Answer:

Sign stimulus

Explanation:

Sign stimulus is a stimulus that will always produce the same behavioral response of an organism. In this case, red coloring is a sign stimulus for the fish attack which is its behavioral response.

This type of innate behavior is called Fixed Action Pattern (FAP) because it is always the same (there is usually no variants in the behavioral response actions). If the model is colored differently, there is no behavioral response (attack).

What is a living cell?

Diano4ka-milaya [45]

Answer:

Though they are often debated, there are eight main characteristics that define a cell as living.

The first is genetic code. All living things contain DNA, which is like the instruction manual for life. DNA is contained in each cell, and passed from parent to offspring.

The second is growth and development. Whether by creating more cells or creating more organelles within the cell, all living things grow and develop.

The third characteristic is reproduction. Reproduction can be sexual or asexual, but in the case of single cells, it is asexual.

The fourth characteristic is response. All living things, including cells, react to external stimuli, such as temperature or salinity.

The fifth characteristic is homeostasis. Homeostasis is the condition by which living things maintain a stable internal environment in the midst of an ever-changing external environment.

The last three characteristics go hand in hand, and are sometimes combined, but in my mind they are distinctly separate.

Sixth is consumption, which is taking in food and other materials. A cell specifically takes in molecules such as water or glucose during consumption.

Seventh is metabolism, which is using materials consumed in order to create energy. Living cells use enzymes to break down materials to produce ATP (adenosine triphosphate), which is usable energy.

Finally, all living cells undergo excretion in some form. Some examples in cells include exocytosis and osmosis.

These 8 characteristics, though often controversial, determine a cell as living.
