Answer: Only some of the organisms survive and reproduce.
Natural selection is a process of differential survival and reproduction in which organisms bearing favorable phenotypic traits survive in changing environmental conditions. Therefore, only some of the organisms survive and reproduce which have suitable phenotypic trait. For example a population of beetle bearing two colors red and green. The green colored beetles mimic the color of grass will remain undetected by birds and those with red color easily observed and detected by birds. Hence, only green beetles are favored for survival over red beetles.
Answer:
Paleontologists may start their investigations by reading articles from the fossil record found in a specific region
Explanation:
Dina may examine the paleontological evidence that includes the study of the fossil record found in her hometown (or closest regions). Moreover, Dina may read research articles on the phylogeography of the species in this area, this information may also help to understand the past climatic conditions
Answer:
C. The graph supports this theory, as it shows a gradual decline in populations of Adelie penguins.
Explanation:
Since Adelie penguins depend on ice to survive, a decline of ice would spell chaos for their survival. And coupled with the fact global warming means a bigger fluctuation of temperatures and a faster melting of ice on Earth, that would line up with the data of the decreasing Adelie penguins.
Hope this helped!
Answer:
The most appropriate answer would be the first option.
Adaptive immunity is a part of the immune system which protects our body against infectious agents with the help of B lymphocytes and T lymphocytes.
It is characterized by its memory that is, it creates the memory of a lifetime for particular antigen or pathogen once it has come across.
As Adrian caught the virus a few years ago his immune system had developed a memory for the virus.
So, as soon as his body contracted the same virus his body recognizes it easily and produce quicker and higher amplitude immune response against it.
Answer:
Mist is made of water vapor.
Explanation:
The bathroom mirror and the fog that the bathroom presents after someone takes a shower, is formed by water vapor. This water vapor is formed by the hot water from showers, which evaporates. This water vapor is what forms the mist, however, when this mist touches the surfaces of the bathroom, such as the mirror, it becomes water again and that smothers the mirror. The mist becomes water when touching the mirror because of the difference in temperature between them, as the mist is hot and the mirror is cold. This happens through the condensation of water.
