<span>Vacuoles are organelles present in plant cells, some animal, and some prokaryotic cells. There is a difference in size between plant and animal cells. Plant cells usually have one large vacuole while animal cells have a number of small vacuoles. If the term "small vacuoles" is used for vacuoles in animal cells, then they are involved in overcoming the foreign particles, storage of waste and during the exocytosis, and invagination of the cell membrane during engulfing the bacteria.</span>
Answer: Wind-blown sand grains striking any solid object in their path can abrade the surface. Rocks are smoothed down, and the wind sorts sand into uniform deposits. The grains end up as level sheets of sand or are piled high in billowing sand dunes.
Explanation:
then it means that they have a survival trait or otherwise known as an inherited trait for survival .. since animals do not have warm houses like us they need to develop fur or something else which means that the skill that is favorable to the environment is an inherited trait

Answer:
they are machines or devices build to find la DNA trace and copy it multiple times.
Explanation:
DNA machines are machines built to find a DNA line and copy it multiple times, so scientists can read, observe, and find information about the DNA strand. For example, DNA machines can determine if someone is related, if someone has cancer, and it can distinguish a person’s ancestry. Mainly this is how forensic science uses to determine when there's a suspect in a crime.
Answer: Beaks---->Evolution, Natural Selction, Genetic Drift, Behavioral Isolation, n Non-random mating...
Explanation:
Darwin observed many discoveries like the Galapagos tortoises, iguanas, penguins, crabs, etc...But one of the most important ones that definitely helped to see the evolution and the process of natural selection is the Galapagos finches they changed a lot mainly because of environmental changes. The Galapagos Islands are special to evolutionary history firstly because there are a lot of different sizes and colors in birds but the main focus was that after Earth was a Pangea, all land united, genetic drift occurred in the Galapagos island meaning that a small population was 'trapped' inside with no way of getting new traits though that's not exactly right because we not only change genetically but also by environmental changes and humans change it too of course(like hunting). Another important discovery that was found there wasn't only hints of evolution and natural selection but also behavioral changes especially in mating, some birds sing or dance it really depends but if some animals don't mate then new species are formed that's one of the reasons why it created a lot of diversity; Another reason to the topic of reproduction is non-random mating, some organisms are looking for some specific location or phenotypes in their mates if they don't find it they look for them in their own species which can cause the extinction of that species or spread it.
