irina [24]

Answer:

b. False

Explanation:

All biomes, even the most remote, are affected by the impact humans have on the environment.

Humans have been causing deforestation, pollution, agricultural expansion, mining, desertification, extinction of animals and plants, burning and other practices that have had extremely negative impacts on biomes around the world.

But if the temperature, the quantity of nutrients are the same in both containers, so the volume is not a variable to affect the speed or low the reproduction rate.

Which structure allows the spinal nerves to exit from the spinal cord?
n200080 [17]

Answer:

Intervertebral foramen

Explanation:

These structures are found in between pairs of vertebrae  and not only do spinal nerves pass through them, the spinal artery, veins, and transforaminal ligaments do too. While the spinal cord passes through the vertebral foramen, the spinal nerves exit and enter the spine through these intervertebral foramen to 'serve' the rest of the body.
