I believe the answer your looking for is they hang upside down all the time this is one of their survival skills! Hope this helps!
Answer:
Genetic drift
Explanation:
Genetic drift is defined as the random change in allelic frequencies from one generation to the other.
Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population, meaning that this effect is inversely proportional to the population size. Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to <u>randomly</u> fixate one of the alleles. Low-frequency alleles are the most likely to be lost. Genetic drift results in a loss of genetic variability within a population.
Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.
Answer:
The mechanism that Darwin proposed for evolution is natural selection. Because resources are limited in nature, organisms with heritable traits that favor survival and reproduction will tend to leave more offspring than their peers, causing the traits to increase in frequency over generations.
Explanation:
Answer:
An organism that eats another organism is called a consumer.
Explanation:
In food webs, consumers are characterized by not being able to produce their own nutrients, having to acquire them from the consumption of other living beings.
Consumers are found from the second level of the food web and can be primary consumers, or herbivores, and secondary, tertiary or even quaternary consumers, who are carnivores.
The other options are not correct, due to:
<em> a. Vertebrate
: which has an internal skeleton, of a bony or cartilaginous nature.</em>
<em> c. Invertebrate: lack of internal skeleton and spine
</em>
<em> d. Embryo: is the product of fertilization, whose development occurs in the uterine cavity or inside an egg.</em>
