Explain how gaseous exchange is achieved in plants (10 marks).
Explanation:
Gaseous exchange in plants is achieved by stomata and lenticels. The epidermis has tiny pores called stomata (singular, stoma) that control transpiration and gas exchange with the air. During the day when photosynthesis occurs, the oxygen released from the process is utilized for respiration

Why do you think An enzyme in a cell became dysfunctional because of an alteration. As a result, the DNA strands would not separate to begin the replication process. Which enzyme has been affected?The eukaryotic DNA requires multiple origins of replication?
Answer:
1. helicase enzyme
2. Eukaryotic DNA is much larger and replication at multiple origins helps reduce the time required for whole genomes to replicate.
Explanation:
1. During DNA replication helicase enzyme is the enzyme that unwinds 2 DNA strands. Hydrogen bonds present between two strands of the DNA helical which are broken by the helicase enzyme and separate both the strands. Unwinding is essential here as it initiates the replication process.
2. There are multiple origin sites in the eukaryotic DNA due to the larger amount of material to be replicated. To reduces the replication time of the entire genome requires multiple origins of replication.

In order for yeast to undergo alcoholic fermentation, what energy
molecule do they need to produce ethanol and CO2?
Answer:
Alcoholic fermentation begins with the breakdown of sugars by yeasts to form pyruvate molecules, which is also known as glycolysis. Glycolysis of a glucose molecule produces two molecules of pyruvic acid. The two molecules of pyruvic acid are then reduced to two molecules of ethanol and 2CO2.

Geological evidence like fossils can be used as evidence for evolution. Which statements below correctly explain how? Choose all that apply. Question 13 options: The relative age of an ancient organism can be used, based on the order of the rocks. The absolute age of a fossil can be determined using carbon dating. Comparative anatomy of fossils provide evidence for common ancestry. Rocks contain creatures that have been living since the beginning of time.
Applied statements that justify the Geological evidence like fossils can be used as evidence for evolution are:
The relative age of an ancient organism can be used, based on the order of the rocks.
The absolute age of a fossil can be determined using carbon dating.
Comparative anatomy of fossils provides evidence for common ancestry.
What are fossils?Fossils are the conserved residues of flora and fauna whose soma were buried in sediments, such as sand and mud, under ancient seas, lakes and rivers. with the passage of time, the newer fossils form a layer above the older ones.
Thus, the relative age of an ancient organism can be used, based on the order of the rocks. the comparative study of fossils do reveal the line of evolution and the common ancestry and The age of fossils can be evaluated by the process of carbon dating.

Answer:
B. cladogram
Explanation:
"A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny. A cladogram is used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors."
The image above represents a cladogram.
A cladogram is an evolutionary tree that diagrams the traditional connections among organisms.
What is a cladogram?
A cladogram is a type of chart that shows theoretical relationships between classes of organisms.
A cladogram compares a tree, with branches off the main trunk. Key elements of a cladogram are the root, clades, and nodes. The root is an initial progenitor that is familiar to all groups branching off from it.
