(you can trust my answers if YOU want too)
-coconut

Answer 1

why did you post the questions and answers allso what grade are you in

Answer 2

100% correct, thanks again coconut!

Answer 3

thank you so much coconut again you are a grade saver

Answer 4

coconut is right but some of the questions are changed.
10. During which phase of Celluar Resperation is Carbon Dioxide released? (Krebs Cycle)
12. How many glucose molecules can undergo cellular resperaation when 13 O2 molecules are available to react? (2)
15. Which activity uses ATP to lower body temperature? (panting)

Answer 5

girl and coconut are both right 100%

Answer 6

also if u have nevada conecctions, #8=electrolysis

Answer 7

So the conclusion I've come to is to 100% trust coconut

thanks coconut whoever you are <3

Answer 11

do we need to do the essay questions?

Answer 12

Epiy yes we do. Duh 🙈

Answer 13

Epiy, no we dont, view the teachers note or ask if there is none. (SCCA 2021 October - Cell Work Unit Test - Honors Biology 1A)

Answer 14

Does someone have the answers for the short essay questions? Here are the questions...

1. Plants in different environments have challenges that only they have. For example, the growth of a plant in a rain forest (e.g., an orchid) might be more affected by different things than a plant in a desert (e.g., a succulent). In three to five sentences, compare environmental challenges that could affect the photosynthetic process of a rain forest plant versus a desert plant.

2. In 3 to 5 sentences, describe the relationship between a glucose molecule and the products it makes during cellular respiration.

3. Remember the law of conservation of mass. The human body uses cellular respiration to make energy. Using the chemical equation for cellular respiration, explain how the amounts of oxygen and carbon dioxide inhaled by the lungs is different from the amounts exhaled. Explain your answer in 1-2 sentences.

4. Dragonflies are flying insects. In the summer, dragonflies can be seen perched on tree branches in an obelisk pose (i.e., a handstand position with the tip of their abdomen pointing upward). In 3–5 sentences, describe how dragonflies might control their body temperature and give reasons for why they might perch in this pose.

Answer 20

ANYOOOOOONNNNNEEEEE

Answer 21

100% thanks to girl and coconut!

Answer 22

Alright, I have the essay answer to number 2...

Aerobic cells use glucose molecules to create ATP (energy) during cellular respiration. This process (cellular respiration) has three main stages: glycolysis, the Krebs cycle and oxidative phosphorylation. Glycolysis occurs in the cytoplasm, whereas the Krebs cycle and oxidative phosphorylation occur in the mitochondria. During glycolysis, a glucose molecule is used to produce 2 ATP, 2 NADH and 2 pyruvate.

The pyruvate is converted to acetyl CoA, which is then converted to oxaloacetate in order to enter the Krebs cycle. The Krebs cycle produces 1 ATP, 3 NADH, and 1 FADH2.

During oxidative phosphorylation, the inner mitochondrial membrane is used to create a proton (H+) gradient, which is used to drive the synthesis of more ATP molecules.

Answer 23

Haha coconut back at it again!!

Answer 24

100% thanks to Coconut again thanks so much!!!!

Answer 25

thanks coconut they were all correct except I had two alternative questions

8. The following are steps of cellular respiration except
C) electrolysis

15. Which activity uses ATP to lower body temperature?
C) panting

these are 100% correct

Answer 26

thank you

Answer 27

number 12 is wrong. It's Ectotherms cannot insulate (stop heat loss from) their bodies and can only control their body temperature by choice.

Answer 28

ESSAY ANSWERS!??????

Answer 29

thank you coconut!!!

Answer 30

i have 12 on cells unit test

Answer 31

i have 15
