I believe it’s b but correct me if I’m wrong
Natural selection is the differential survival and
reproduction of individuals due to differences in phenotype. It provides a
viable explanation for adaptation and speciation as it explains the change in
heritable traits characteristic of a population over time. Changes that allow an organism to better adapt
to its environment will help it survive and have more offspring. Natural
selection can change a species in small ways, causing a population to change
color or size over the course of several generations. Given enough time and
enough accumulated changes, natural selection can create entirely new species. It
can turn dinosaurs into birds, amphibious mammals into whales and the ancestors
of apes into humans.
<u>Answer</u>: 2.soil minerals, oxygen, rain, sunlight.
<u>Explanation</u>:
- <em>Abiotic factors </em>are the non-living and physical factors of the environment. For example, rocks, wind, soil etc.
- The<em> biotic factors </em>are the living components of the environment for example plants, animals etc.
- Since <em>soil minerals, oxygen, sunlight, and rain are all non-living components they all fall under the category of abiotic factors. </em>
Answer:
An older female squirrel that sounds an alarm call to warn her relatives of an approaching aerial predator
Explanation:
Kin selection is the evolutionary adaptive strategy that increases the survival rate of the organism by increasing the reproductive success of the genes and other close relative genes.
The organism increases the chance of survival of the close relatives and their offspring at their own cost.
The kin selection behavior is observed in many species including humans, bees, wasps, squirrels, and many others.
In the given question, the squirrel especially an old squirrel gives an alarming call when a predator comes in their range which allows enough time to run away from the predators and increase the reproductive rate of the population.
Thus, the selected option is correct.
<span>Homologous structures refer to structures that have similar characteristics in terms of morphology, anatomy, genetics, and embryology yet still different when their functions are concerned. On the other hand, analogous structures are those organisms that have similar lifestyle because they live in the same habitat yet they belong in different groups.</span>
