<h2>Natural selection </h2>
Explanation:
Malthus's ideas about geometric population growth implied that: resources in every generation would be limited, therefore individuals in every generation would have to compete for those resources
- Thomas Malthus argued that the food supply increased linearly while population size increased exponentially
- The central theme of Malthus' work was that population growth would always overpower food supply growth, creating perpetual states of hunger, disease, and struggle
- The natural, ever-present struggle for survival caught the attention of Darwin, and he extended Malthus' principle to the evolutionary scheme
- Malthus’ writings ultimately inspired Darwin’s theory of evolution by natural selection
resources in every generation would be limited, therefore individuals in every generation would have to compete for those resources.
Answer:
The correct answer will be option-D
Explanation:
Pulmonary Surfactant is a complex substance produced by the pneumocytes epithelial II cells in the alveolar sac.
The surfactant is composed of the proteins and lipids which plays a role in keeping alveoli open by reducing the surface tension formed between the air and liquid.
The surfactant act by forming a monolayer surface film which helps reduce the surface tension.
Thus, option-D is the correct answer.
Answer:
B
Explanation:
I'm not entirely sure, it could be B, or D. my research has made me lean more to B though..
<h3>Answer:</h3>
Sample-C is the hydrogen.
<h3>Solution:</h3>
Data Given:
Volume = 5 cm³
Mass of Sample-C = 0.00045 g
Reference Density = 0.00009 g/cm³
Formula Used;
Density = Mass / Volume
Density = 0.00045 g / 5 cm³
Density = 0.00009 g/cm³
