Answer:
The answer is A.
Explanation:
In the case of cyanide poisining which prevents the oxygen from being used by the body, the brain is one of the first organs that gets effected because it uses around 20% of the total oxygen intake of the body and the other systems and organs mostly depend on the brain to function properly so the brain runs out of oxygen before the other parts of the body.
I hope this answer helps.
In this experiment, researchers compared how fast the junco populations adapted.
<h3>What is the focus of the study?</h3>
This study focuses on the adaption process of Juncos (a specific bird population) in urban environments and how they behave in terms of stress and boldness behavior (interest in exploring unknown areas).
<h3>How did the study work?</h3>
In this study, scientists compared the behavior of a population of birds in an urban area with the behavior of another population of birds that lived in a novel urban area to determine the adaptation process of the second population.
Note: This question is incomplete because the information about the study is missing; here is the name of the possible study: Boldness behavior and stress physiology in a novel urban environment suggest rapid correlated evolutionary adaptation

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.
Answer: Hydrogen bonds
Explanation: The CAS9 enzyme affect the bond between the deoxyribose sugar and the phosphate backbone of the PAM sequence in the target DNA
The undulations on the cerebral cortex (the outer layer of the brain) are called gyri (ridges) and sulci (gorges). Also called the grey matter, the cerebral cortex is the core of brain functioning region with approximately 20 billion neurons.
It is believed that the cerebral cortex is highly folded to accommodate many neurons.
