Answer:
B) speciation.
Explanation:
The Galapagos island is known for the different varieties of finches (species of birds) which could be distinguished on the basis of different beak shapes and size.
This is the result of the selection pressure which led to the divergence of the species on the island through a mechanism called adaptive radiation.
Since the adaptive radiation leads to the formation of different species on the same island, the process of formation species is known as the speciation.
Thus, speciation is the correct answer.
<u>Avions</u>.
Step by step Explanation:
This is because, terrestrial animals live only on land, while aquatic animals live only in water and amphibians like frogs live both in land and water.
From the above the options, they live either in land or water but not in air or fly.
Therefore, the answer is <u>Avions</u>
The youngest rock is found near mid-ocean ridges since a new rock is formed near the mid-oceanic ridge as oceanic plates diverge or separate from each other. Hot rocks rising from the asthenosphere melt from decompression as they rise, filling the fault and forming new basaltic oceanic <span>crust. As new crust is added, older crust is pushed away. Hope this answer helps.</span>
Answer:
An aqueous solution of carbohydrates, proteins , lipids, nucleic acids and inorganic salts surrounded by a cell membrane is called as cytoplasm.
The cytoplasm has three main components:
Cytosol:
It includes 70% of the total cell composition. Water is the main composition of the cytosol. It dissolves in it various inorganic and organic salts in it which bears ionic charge in them and carry out chemical reactions necessary for cellular metabolism. It contents macromolecules like proteins and lipids. Other than lipids all the macromolecules are dissolved in the water based on their polarity and can be used as a storage reservior for energy.
Organelles:
Cytoplasm contained within it many organelles like mitochondria, golgi apparatus, ribosomes, plastids, lysosomes, vacuole. Organelles like ribosome and mitochondria produces nucleic acids DNA and RNA. These organelles synthesize carbohydrates, proteins, nucleic acids, enzymes, non-organic salts.
Cytoplasmic inclusions:
These are the tiny particles suspended in the cytosol. Example include lipid droplets these are the spherical droplets made up of lipids and proteins are present in both prokaryotes and eukaryotes as a medium for storing lipids like fatty acids and sterols. These particles are chief components for adipocytes, the fat storing cells.
