Carbon Cycle - Please answer the following using the words in the word bank

(Word bank words can be used either once, or not at all).

Plants and other photoautotrophs use CO2 (carbon dioxide) in the process of to make and oxygen. Both plants and animals use oxygen in the biological process of and make CO2. The is the main regulator of CO2 in the atmosphere, because it covers most of the Earth, and CO2 dissolves easily in it. Millions of years ago, huge deposits of carbon were stored, which were formed from dead plants and other organisms. Today these carbon rich deposits are burned as fossil fuels, which include , , and . More CO2 is released in the atmosphere today than in the past because of the .

Question 1

Plants and other photoautotrophs use CO2 (carbon dioxide) in the process of photosynthesis to make glucose and oxygen. Both plants and animals use oxygen in the biological process of respiration and make CO2. The ocean is the main regulator of CO2 in the atmosphere, because it covers most of the Earth, and CO2 dissolves easily in it. Millions of years ago, huge deposits of carbon were stored, which were formed from dead plants and other decayed organisms. Today these carbon-rich deposits are burned as fossil fuels, which include coal, oil, and natural gas. More CO2 is released in the atmosphere today than in the past because of the burning of fossil fuels. But carbon dioxide is a greenhouse gas, as is water, and methane, and too much CO2 and other greenhouse gases produced by human activities in the atmosphere may be responsible for human-accelerated climate change.

Question 2

Scientists who study meiosis are most likely trying to answer which question?

  • d What enables the creation of unique genetic combinations?

Question 3

What is the percent chance that the offspring will have a single comb?

  • Since the parents have genotypes Aa and Aa, we can set up a Punnett square. The possible offspring genotypes will be: AA, Aa, Aa, aa. Thus, one of the four combinations will result in a single comb (aa).

Question 4

Based on the information in this table, which men could not be the father of the baby?

  • Without specific genotypical data concerning the men's genetic traits compared to the baby's, it's not possible to determine the answer. Generally, you would analyze the possible combinations via a Punnett square. Assuming you have options, select ALL correct answers based on the existing information and Punnett squares you've constructed.

Question 5

This bacteria is an example of...

  • a asexual reproduction

Question 6

Which species most likely performs photosynthesis?

  • a Species Q (assuming this species is found in shallower depths where light penetrates)

Question 7

  • b The arrows represent the flow of energy in one direction from producers to consumers.

Question 8

Which is a negative impact of destroying the rainforests?

  • b decreased oxygen in the atmosphere

Question 9

As DDT (or other persistent chemical that can biomagnify) moves up the trophic level in food chains, or food webs, its concentration ____.

  • c increases
