Answer:
This question lacks options; the options are:
A) Artificial selection
B) Stabilizing selection
C) Disruptive selection
D) Directional selection
The answer is D) Directional selection
Explanation:
Changes in the environmenal condition affects the distribution of organisms phenotypes. Via this change, organisms with certain traits are naturally selected. The types of natural selection are; stabilizing, disruptive and directional.
Based on the description of the selection in this question, the type of selection is DIRECTIONAL. Directional mutation is that in which one of the two extreme phenotypes in a population is selected against while the other is favored by the occurrence of a natural environmental hazard. The distribution gradually shifts to favour one extreme over the other until the other unselected extreme gets extincted.
This is the case regarding a population of finches affected by drought caused by flood causing all their food source to disappear leaving only ant hills that certain finches with thin beaks can access. This environmental change favorably selects one extreme phenotype (finches with long thin beaks). Hence, a type of DIRECTIONAL selection
Answer:
Please see below for answer
Explanation:
As the new flock of birds arrives in the city, there will be a sudden surge in the population of these birds. Since there are no predators of the birds around in this city, the population will remain at a higher number as time passes by during the next decade or so.
Answer:
Cell organelle
Explanation:
The cell organelle is the small organ-like structure present inside the cell in the cytoplasm.
Different types of cell organelles are present in the cell which performs specific functions like of storage, of digestion of biomolecules like lysosomes, of protein synthesis and many others.
The organelles are usually enclosed by either a single phospholipid membrane like in lysosomes, Golgi apparatus or two lipid layers like in nucleus and chloroplast.
Thus, cell organelle is the correct answer.
Answer:
Convergent.
Explanation:
The collision between two lithosphere plates on the surface of earth results in the formation of convergent plate boundaries. The process of subduction occurs when one plate converges over the other plate.
The diagram given in the question shows the convergent plate boundary. The collision of two lithospheric plates have been represented in the picture.
Thus, the correct answer is option (A).
