Answer:
The light speckled moth
Explanation:
<em>Biston betularia</em> or peppered moth is a moth that is very commonly present in Asia, Europe and North America. Normally it occurs in two forms:
1) A dark morph
2) A light, speckled morph
The peppered moths are a frequent target of birds but they are smart enough to rescue themselves against predator birds by selecting appropriate location for their habitats. For example: If a forest contained mostly light colored trees , light, speckled morphs will be more abundant there because due to a matching color with trees they will be less visible to birds and other predators. Similarly, If a forest contained mostly dark colored trees,dark morphs will be more common so that they rescue themselves due to camouflage from the attack of birds.

Answer:
A) within the lumen of the small intestine.
Explanation:
The pancreas produces a variety of hormone-like amylase, proteases, lipases which can digest the food material.
The proteases like chymotrypsinogen and trypsinogen are produced by the pancreas in their inactive form as if active will digest the organ itself. Therefore these zymogens are stored in the secretory vesicles which release the enzymes in the pancreatic duct.
These zymogens are not activated until they reach the digestive tract that is when these enzymes enter the lumen of the small intestine, the enterokinase present there catalyzes the trypsinogen to trypsin. Trypsin converts the chymotrypsinogen to the chymotrypsin.
Thus, Option-A is the correct answer.
Explanation:
the plant in the sunlight will receive green color due to chlorophyll and the plant in the dark will have yellow or white color due to the lack of chlorophyll
<span>Hersey and Chase labeled the outer protein coat of a bacteriophage with radioactive sulfur, and the inner DNA with radioactive phosphorous. After allowing the bacteriophage to infect E.coli bacterium and undergoing a heavy blender process, the empty "ghost" phages were separated from the bacteria. The infected E.coli were positive for radioactive phosphorous, indicated that DNA was the genetic material inserted from the bacteriophage. The radioactive sulfur was not present in the infected bacteria, indicating that protein was not the genetic material.</span>
