Question 1: Purpose of Aerobic Respiration

Answer:

To release energy from food and store it in ATP for cellular use

Question 2: How are traits passed through chromosomes?

Answer:

Genes on chromosomes are inherited from parents, carrying the genetic information for traits

Question 3: Example of homologous structures

Answer:

Forelimbs of humans, whales, and birds have similar bone structures due to common descent Question 4: Evidence: cooperative hunting

Answer:

Predators like lions hunt in groups to take down larger prey more successfully

Question 5: How do mutations and sexual reproduction contribute to variation?

Answer:

Mutations introduce new traits; sexual reproduction shuffles genes creating diverse trait combinations

Question 6: Gene

Answer:

A segment of DNA that codes for a specific protein

Question 7: New Ecosystem Formation

Answer:

When changes are severe, the original ecosystem may be replaced by a different one with new species and interactions

Question 8: Stem cell research

Answer:

Studies stem cells' ability to treat diseases and repair damaged tissues by directing differentiation

Question 9: Multicellular Organism

Answer:

An organism made up of many specialized cells and systems working together

Question 10: Investigation of Feedback

Answer:

Can include measuring changes in heart rate, stomate opening, or root growth in different conditions

Question 11: Aerobic Cellular Respiration

Answer:

A process where cells break down glucose using oxygen to release energy

Question 12: What effect does competition have on evolution?

Answer:

It favors individuals with traits better suited to obtain limited resources

Question 13: Carbon in the Biosphere

Answer:

Carbon is stored in living organisms and released through processes like respiration and decomposition

Question 14: Structural Proteins

Answer:

Proteins that provide support and shape to cells and tissues (e.g., collagen)

Question 15: Role of endocrine system in reproduction

Answer:

Regulates reproductive hormones that influence sexual development and function

Question 16: Computational Models

Answer:

Simulations and computer models that predict ecosystem responses to different environmental conditions

Question 17: Elements in Sugar Molecules

Answer:

Carbon, hydrogen, and oxygen

Question 18: Evaluating Solutions

Answer:

Monitoring environmental indicators and biodiversity to assess effectiveness of solutions

Question 19: Root Growth and Water

Answer:

Plant roots grow toward areas with more water to maintain hydration and support survival

Question 20: How does natural selection change gene frequencies?

Answer:

Natural selection changes gene frequencies by increasing the frequency of alleles that contribute to advantageous traits and decreasing those linked to less favorable traits.

Question 21: Mathematical Representations

Answer:

Graphs, charts, and data analysis tools used to support and revise explanations about biodiversity and populations

Question 22: Improved reproduction

Answer:

Migrating or breeding in groups improves chances of finding better breeding grounds and higher offspring survival rates

Question 23: Structure of DNA

Answer:

composed of two strands that form a double helix. The strands are made up of nucleotides, which include a sugar, a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine)

Question 24: Human Impact on Carbon Cycle

Answer:

Activities like burning fossil fuels increase atmospheric CO2 and affect climate balance

Question 25: Heart Rate and Exercise

Answer:

Heart rate increases during exercise to supply more oxygen, helping maintain stable oxygen levels

Question 26: Formation of Complex Molecules

Answer:

Chemical reactions rearrange elements from simple molecules to build lipids, proteins, starches, and nucleic acids

Question 27: Carbon in the Geosphere

Answer:

Carbon is stored in rocks and fossil fuels and released through geological processes and combustion
