Based on the characteristics above, this toxin can be categorized as EXOTOXIN. These toxins (exotoxins) are produced by different types of bacteria.
Exotoxins are a broad category of proteins produced by bacteria that enter host cells in order to alter their physiological properties.
These toxins (exotoxins) can be secreted by Gram-negative bacteria and Gram-positive bacteria.
Examples of exotoxins include botulinum toxin secreted by Clostridium botulinum bacteria, tetanospasmin toxin secreted by Clostridium tetani bacteria, etc.

which is not part of the conducting portion of the respiratory system?
Answer:Which is not part of the conducting portion of the respiratory system? The epithelial lining of the oropharynx and the superior larynx (vocal cords) is nonkeratinized stratified squamous. In general, respiratory zone structures are lined with a thicker mucosa than conducting zone structures.
Explanation:
brainliest pls
The part that is not the conducting portion of the respiratory system is the alveoli, which is in option D, as this is not a part of the conducting portion but a part of the respiratory system. So, option d is correct.
The alveoli are small, thin-walled sacs located at the end of the bronchioles in the lungs. They are responsible for gas exchange, where oxygen is taken up from the inhaled air and carbon dioxide is released into the exhaled air. While the alveoli are an essential part of the respiratory system, they are not considered part of the conducting portion. Instead, they are part of the respiratory portion, where gas exchange occurs. So, option d is correct.

Which molecule supplies chlorophyll with electrons
In light reactions, a molecule of chlorophyll absorbs one photon of light, causing a chlorophyll electron to transfer to a higher energy level. The energized electrons from the chlorophyll molecules flow down a transportation chain to a compound called nicotinamide adenine dinucleotide phosphate or NADP.
▪▪▪Cutest Ghost▪▪▪Water is the molecule that supplies chlorophyll with electrons.
What happens during photosynthesis?Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose (sugar) and other carbohydrates. This process also produces oxygen as a byproduct.
During the process of photosynthesis, chlorophyll absorbs light energy, which is used to split water molecules into oxygen and hydrogen atoms. The hydrogen atoms are then used to generate ATP and NADPH, which are used to power the process of carbon fixation. The oxygen atoms are released as a byproduct of water splitting and become a part of the oxygen in the Earth's atmosphere.

2. Write a micro-theme(short paragraph 100-300 words) using and explaining the following terms.
a. "Survival of the fittest"
b. Adaptation
c. Evolution
Answer:
The process through which creatures evolve is known as evolution. Mutations cause genetic variety throughout populations, and the ecosystem works with this diversity to select people who are most suited to their surroundings. Eventually, a species can develop into a plethora of others; as a theory suggests that sapiens started as monkeys but evolved into the humanoid beings that we are today. In biology, adaptation is the procedure where a species fits to its habitat; it is the outcome of natural selection acting on hereditary diversity over numerous generations. Survival the fittest is a saying that suggests the fittest survive, not the weak. This is commonly seen in everyday life, whether with humans, animals, plants, it holds the same meaning. An example would be that a person in better physical and mental health would go farther and live longer than one with weak physical and mental health.
The concept of "survival of the fittest" is a key tenet of evolution, which refers to the idea that individuals with traits that provide them with a competitive advantage in their environment are more likely to survive and reproduce than those without these traits. This process of natural selection leads to the gradual accumulation of beneficial traits in a population, resulting in adaptation and evolution over time.
What is adaptation?Adaptation refers to the process by which organisms develop characteristics that allow them to better survive and reproduce in their environment, such as camouflage or the ability to digest new types of food.
Evolution refers to the broader process of change over time in a population's genetic makeup and physical characteristics, resulting from the interaction between genetic variation, natural selection, and other factors. Together, these concepts help explain how organisms are able to adapt and change over time, resulting in the diversity of life that we see today.
The study of evolution has important implications for understanding the history and development of life on Earth, as well as for addressing modern challenges such as biodiversity loss and climate change.

Describe an example of how island biogeography principles were used to explain biodiversity changes in areas that were not specifically islands.
Answer:
How Biogeography Affects Biodiversity
Alfred Russel Wallace, Father of Biogeography
Figure 1: Alfred Russel Wallace, Father of Biogeography
Some places contain more species than others. For example, Antarctica has fewer species than a temperate deciduous forest, which in turn has fewer species a tropical rainforest. For over 150 years, researchers have sought to make sense of the gross and fine scale spatial patterns in biodiversity, and to elucidate both the proximate and ultimate causes for these patterns.
This article describes some of the major geographic patterns in species richness, and the processes and theories that are thought to account for these patterns. Much of this knowledge has emerged from the tremendous body of work from one scientist, Alfred Russel Wallace (Figure 1), widely regarded as the “Father of Biogeography.” Aside from co-originating the process of Natural Selection with Charles Darwin, Wallace spent extended periods studying the distribution and diversity of plants and animals in Amazonia and Southeast Asia in the mid 1800s. Many of the patterns and processes featured in this article were initially described by Wallace, and careful study of his work indicates that his ideas presaged many of the discoveries made by his numerous successors.
Many of the spatial patterns in biodiversity are overt, others are subtle and yet additional patterns remain undetected. While the existence of these patterns may be obvious — and changes in the environment that are paired with these patterns may also be obvious — the mechanisms that cause the differences in biodiversity along environmental gradients are under still the subject of scientific debate. Because large-scale patterns are the emergent result of complex interactions at many spatial and temporal scales, no single answer is likely to ever emerge, but with continued research our understanding of the processes shaping these patterns increases.
Historical Processes Affecting Biogeography
Darwin's finches of the Galapagos Islands are a classic example of adaptive radiation.
Figure 2: Darwin's finches of the Galapagos Islands are a classic example of adaptive radiation.
All species occurring in at a given place and time either arrived from another place or originated in that location from ancestral species. This fact applies to extinct species that were ancestors of all extant species. Species richness in a given location is the result of three factors — the rate of speciation, the rate of extinction, and the dispersal of species from other locations. In principle, if biogeographers could understand how the current and past environment has shaped these three factors, we would then obtain a comprehensive understanding of what generates all biogeographic patterns of species richness. However, numerous environmental and organismal parameters can drive these historical factors, in both complex and interacting fashions.
