Answer: fracture

Explanation:

Minerals are formed by crystallization from magmatic liquids or thermal solutions, by solid-state recrystallization and further, as the product of chemical reactions between solids and liquids. Fracture: When minerals do not break flat but according to an uneven surface. The types of fracture can be classified into:

• Conchoidal: when the mineral breaks, leaving curved marks similar to the growth lines of shells. Ex: quartz.

• Irregular: When the mineral breaks randomly, forming rough and uneven surfaces. Ex: tourmaline.

• Fibrous: when the mineral breaks down in the form of fibers. Ex: chrysotile.

• Serrated: when the mineral breaks up according to a jagged surface with sharp edges. Ex: gold.

Which regions of the nephron function independently of hormonal control for the most part?
alexgriva [62]

Answer:

Renal corpuscle, proximal tubule, and loop of henle.

Explanation:

Renal corpuscle is blood filtering part of the nephron which consist of Bowman's capsule and glomerulus. It works independently of hormonal control and filter the blood circulate through this glomerulus.

Proximal tubule is the component of nephron which starts from the renal pole of Bowman's capsule to the loop of henle and it involves in the selective reabsorption of glucose, peptides, water and other nutrients from tubule to the blood. It works independently of hormonal control.

Loop of henle is the U shaped part of nephron which is responsible for absorption of water and sodium chloride from urine to back into blood circulation. It is also work independently of hormonal control.

What advantage is there to phosphoglycerate kinase having an open and closed configuration?
Andrej [43]

Answer:

The correct answer is "The induced-fit mechanism maximizes accessibility of active site without sacrificing hydrophobic environment".

Explanation:

Phosphoglycerate kinase is an enzyme that participates in a step of glycolysis by transferring a phosphate group from 1,3-bisphosphoglycerate (1,3-BPG) to ADP, generating the following intermediary compound and a molecule of ATP. The phosphoglycerate kinase has an open and closed configuration, which has the advantage that the induced-fit mechanism maximizes accessibility of active site without sacrificing hydrophobic environment. This help the enzyme to have a more stable configuration and regulates its use in glycolysis.

Humans and apes have five fingers they can use to grasp objects. do you think these are analogous or homologous structures? expl
zavuch27 [327]
Analogous structures are structures with different evolutionary ancestries but they have the same function. Examples include; wings of birds, insects and bats. On the other hand homologous structures have similar ancestries and common traits but may not have the same function in an organism. Well; in the above question Human apes have five fingers they can use to grasp objects, which i think these are homologous structures.
