kolezko [41]2 years ago
4 0

The founder effect is the loss of genetic variety that happens when a new population is founded by a small number of individuals from a larger population, according to population genetics. Ernst Mayr was the first to thoroughly explain it in 1942, based on previous theoretical work by people like Sewall Wright.

nydimaria [60]

The answer is copper. Nonrenewable resources are those that cannot be readily/naturally replaced at rates that match those of consumption (an aspect that allow renewable resources to be sustainable). Copper are made deep in earth at very slow rates hence do not readily renew themselves. Organisms, on the other hand die, and are naturally replaced by offspring.

what were the historical reasons for the resistance to recognizing airborne transmission during the covid-19 pandemic?
ExtremeBDS [4]

Up until a 1962 demonstration of tuberculosis airborne transmission, airborne transmission of all major respiratory diseases was assumed to be of insignificant or moderate consequence over the following fifty years.

Before COVID-19, only a small number of diseases—those that were blatantly spread to people not in the same room—were generally acknowledged as airborne. This is because the contact/droplet paradigm remained popular.

<h3>What does the term "airborne transmission" mean?</h3>
  • The term "airborne transmission" refers to the propagation of droplet nuclei (aerosols) that retain their infectious properties after being suspended in air for a lengthy period of time and over great distances.
  • Bacteria or viruses that cause airborne infections are most frequently spread by tiny respiratory droplets. When a person with the airborne sickness sneezes, coughs, laughs, or exhales in any other way, these droplets are released.

1. Photosynthesis and cellular respiration are often described in two ways: (1) They are chemically opposite; and (2) They have
SVEN [57.7K]

Answer:

Photosynthesis and cellular respiration are chemically opposite. The reactants of photosynthesis are energy, carbon dioxide (6CO2), and water (6H2O). The products of cellular respiration are energy, carbon dioxide, and water. The products of photosynthesis are glucose (C6H12O6) and oxygen (6O2), and the reactants of cellular respiration are glucose (C6H12O6) and oxygen (6O2). So, the processes' equations are chemically opposite. The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. Without photosynthesis, cellular respiration couldn't take place, and without cellular respiration, photosynthesis couldn't take place. It's like a cycle.
