Explanation:
The length of the sperm in a few species is much larger or giant than the size of the animal-like observed in the <em>Drosophila bifurca.
</em>
In this fruit-fly, the tails of the sperm are too long which could be accounted for many reasons:
1. The sexual selection prefers the long tails over the small tail.
2. The large sperms can displace the small sperms in the female reproductive organ.
3. The female reproductive organ increases the promiscuity of the large sperms that is favour the large sperms over the small sperms.
Population extinction is a natural occurrence, but because the pace of extinction on a global scale is increasing, understanding extinction is crucial for conservation. To evaluate proposed extinction processes, the rate of extinction in experimental populations of brine shrimp (Artemia franciscana) was evaluated. As was predicted, the chance of extinction was decreased by a larger initial population, a larger maximum population size supported by the environment, and less change in environmental variables. However, contrary to popular belief, maximum population size and environmental variation were more significant than initial population size. Unexpectedly, the importance of deterministic population oscillations brought on by inborn nonlinear dynamics and overcrowding was equal to or greater than that of the assumed processes.
<h3>What is
extinction?</h3>
Extinction happens when species become endangered due to environmental factors such habitat loss, climate change, natural disasters, human overuse, and pollution, or because of evolutionary changes in its constituent parts.

Answer:
d. Most climate scientists believe that there is evidence that explains global warming.
Explanation:
From the passage, we know that a whooping 97% of climate scientists agreed that human activities is causing global warming.
From this, we know that climate change is caused by human activities.
The study clearly shows that there is known cause of climate change and it is due to human activities.
a. Most climate scientists dispute the theory of human influence on global warming.
This is false and does not agree with the passage. Infact most climate scientists agree to the fact that humans contribute the most to global warming.
b. Global warming is most likely alarmist propaganda based on false data.
The paragraph shows a scientific study from which the conclusion was drawn
c. Global warming is definitely not caused by human influence on nature.
This is false
Hello!
In order to find the correct answer, you need to find a hypothesis that cannot be proven wrong. Out of the options in the prompt, all but one can indeed be proven wrong. The correct answer is A because there is no way anyone can tell if there is a teacup orbiting the Milky Way galaxy or not. We know that it can be proven wrong there is no life on Mars, the human species started in Africa and that humans cannot live without a certain amino acid. The only thing that really can’t be proven wrong (that is quite stupid) is the one about a teacup.
Upon studying the theory of falsifiability, I came across an example of a person who claimed they had invisible unicorns in their digestive tract. We know that this (incredibly dumb) example cannot be proven wrong because, well, there is no way to actually know what’s in someone.
