When compared to eukaryotic cells, prokaryotic cells are:

60% Answer Correctly

	more complex
	none of these
	less complex
	similarly complex

Solution

Cells are classified into one of two groups based on whether or not they have a nucleus. Eukaryotic cells have a nucleus, prokaryotic cells do not have a nucleus and therefore have a less complex structure than eukaryotic cells.

Which of the following is not part of the carbon cycle?

59% Answer Correctly

	decomposition
	precipitation
	respiration
	photosynthesis

Solution

The carbon cycle represents the ciruit of carbon through Earth's ecosystem. Carbon dioxide (CO₂) in the atmosphere is absorbed by plants through photosynthesis. Plants then die and release carbon back into the atmosphere during decomposition or are eaten by animals who breathe (respiration) the carbon into the atmosphere they exhale and produce waste which also releases carbon as it decays.

This skeletal system is common in arthropods like insects, spiders, and crustaceans.

81% Answer Correctly

	endoskeleton
	vertebrate
	bone
	exoskeleton

Solution

An exoskeleton (external skeleton) is common in arthropods like insects, spiders, and crustaceans.

"An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force." This describes which of Newton's laws of motion?

73% Answer Correctly

	first
	third
	fourth
	second

Solution

Also known as the law of inertia, Newton's first law of motion states that An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

In the food chain, bacteria and fungi convert the organic matter in the dead bodies of plants and animals into simple nutrients. Bacteria and fungi are:

86% Answer Correctly

	producers
	scavengers
	primary consumers
	decomposers

Solution

Decomposers (saprotrophs) are organisms such as bacteria and fungi that break down the organic matter in the dead bodies of plants and animals into simple nutrients.
