QUESTION 1 1.1 Define Kinetic energy. (2) 1.2 Explain how energy is
transferred in an ecosystem. (2) 1.3 What is the main purpose of
photosynthesis in plants? (2) 1.4 What is cellular respiration? (2) 1.5
Compare aerobic and anaerobic respiration. (4) 1.6 What is the role of ATP in
cellular processes? (2) 1.7 Explain how ATP is synthesized in the
mitochondria. (3) 1.8 What does ADP stand for? (1) 1.9 Explain the process of
converting ADP to ATP. (2) 1.10 Insert a screenshot to show your
contributions to one of the engagements in the first unit. (Take this from the
discussion forum based on unit 1) (2) [22]
QUESTION 2 State whether the statements below are True or False. 2.1
Energy cannot be created or destroyed, only transferred or converted from
one form to another. 2.2 Photosynthesis occurs in the mitochondria of plant
cells. 2.3 Cellular respiration produces oxygen as a byproduct 2.4 ATP is the
primary energy currency of the cell. 2.5 ADP has more stored energy than
ATP. 2.6 A phylogenetic tree is used to show evolutionary relationships
among species. 2.7. Human somatic cells are diploid, containing two sets of
chromosomes. 2.8 Gametes are haploid cells, meaning they contain two sets
of chromosomes. 2.9 Summative assessment is conducted during the
learning process to provide ongoing feedback to students. [9x2=18]
QUESTION 3 3.1 Using your understanding of the principles of evolution,
analyze the evolutionary relationship between two hypothetical species,
Species A and Species B. Species A is found in tropical rainforests, while
Species B inhabits arid deserts. Consider the following components in your
response: 4 3.1.1 Describe two specific adaptations each species has
developed to survive in their respective environments. Explain how these
adaptations enhance their survival and reproduction. (4) Distribution of
marks: Identification of Adaptations 2 Explanation of Survival and
Reproduction 2 3.1.2 Discuss the possible evolutionary mechanisms (e.g.,
natural selection, genetic drift, mutation) that could have led to the
divergence of Species A and Species B from a common ancestor. Provide
examples to illustrate your explanation. (4) Distribution of marks: Discussion
of Mechanisms 2 Examples and Illustration 2 3.1.3 Insert a screenshot to
show your contributions to one of the engagements in the first unit. (Take
this from the discussion forum based on unit 2) (2) 3.2 Read the following
statements and identify whether each one describes a formative or
summative assessment. 3.2.1 A teacher provides ongoing feedback during a
project to help students improve their work before the final submission. 3.2.2
At the end of the term, students take a comprehensive exam covering all the
material studied throughout the course. 3.2.3 Students participate in peer-
review sessions where they give and receive constructive feedback on their
