Answer:

Choice C. Sodium bicarbonate acted as a pH buffer in Solution 2.

Explanation:

Sodium carbonate is used as pH buffering agent. Buffering agent is a type of solution which contains weak base or acid which stabilize the solution when another strong acid or base is added to the solution. If acid is added, the weak base that is present in the solution reacts with it and when base is added, weak acid reacts with it.

Which of the below features was not used to identify the early Homo distinction from Australopithecines
Jlenok [28]

The correct answer is reduction in tooth size.

The anatomy of the foot and pelvis are the feature of Australopithecus afarensis that is used to definitively classify this species as a hominin.

<h3>Australopithecines</h3>

Australopithecines are an adaptive radiation of early hominins, all of which were to some extent bipedal, had brains that were only slightly larger than those of apes, and had adaptations to a diet that included at least occasionally hard-to-chew items. They have been identified through research on perhaps ten species that lived in central, eastern, and southern Africa between 4.2 million and 1.0 million years ago. Understanding australopithecines is essential to comprehending not only the diversity of early hominins but also the origins of Homo. Our genus Homo probably originated from this radiation, albeit we are unsure from which species.

In a cell with defective chaperones, Question 14 options: proteins would not be able to exit the ribosome. the concentration of
BartSMP [9]

Answer:

the concentration of misfolded proteins would be higher than normal.  

Explanation:

Chaperones proteins are required for the correct protein folding of proteins. These proteins were first discovered in bacteria. The level of chaperones is increased under thermic stress conditions, it is for that reason that they are also known as heat shock proteins (Hsp). For example, Hsp70 is a chaperon protein constitutively expressed under stress conditions that is involved in the folding of protein precursors and the refolding of misfolded proteins. In humans, Hsp70 is encoded by the HSPA1A gene, and its increased expression level is related to different health problems including neurodegenerative diseases, cerebral ischemia and epilepsy.
