Answer:
Option D, spatial reproductive isolation—the only reason these two species don’t mate is because of the inability of the middle land to be occupied
Explanation:
It is clear from the question that the two bird populations with different color are able to mate and reproduce viable and fertile offspring when brought together. Hence, the only problem due to which these two bird population were not breeding with each other was their distant location and habitat.
Location and habitat are characteristic of spatial distribution and hence they were separate because of spatial reproductive isolation
Hence, option D is correct
The correct options are:
- Matter is made of small particles.
- Matter's particles are in constant random motion or vibration
- There is empty space between matter's particles.
Anything which has mass and occupies shape is a matter. Matter is composed of particles. The particles of matter are very small in size and they attract each other. There is space between the particles. The particles are in continuous random motion, thus they have kinetic energy. on absorbing energy their movement increases.
Answer:
Hello!
The answer is B. It is made up of amino acids.
Explanation:
Collagen:
Collagen is the most abundant protein found in mammals and makes up 25%of the entire protein count. Collagen is mostly present in the form of collagen fibers which give the extracellular matrix structure and support.
Amino acids:
Amino acids are organic molecules that possess the amino (-NH2) functional group. Amino acids are the building block of proteins. They combine together through peptide linkages to form polypeptides and polypeptides link together in the form of complex proteins.
Collagen possesses a complex structure of amino acids arranged in three alpha-chains wound around each other to give a triple-helix.
Answer:
Evaporation and Transpiration
Explanation:
Evaporation occurs when water molecules transfer from liquid water into the air and transpiration is water vapor escaping from pores in plants
Physical Factors:Physical factors that affect population distribution include altitude and latitude,relief,climate,soils,vegetation,water and location of mineral and energy resources.
