The way that a mineral breaks can help to identify that mineral. Some minerals have a tendency to split evenly along specific or straight planes, this is called cleavage; other minerals break in more of an irregular pattern is called as fracture.

Answer: Option C

<u>Explanation:</u>

Cleavage refers to the manner in which a few minerals break along specific lines of shortcoming in their structure. Mica is a best example as it breaks along firmly divided level planes that yield slim sheets.

Calcite is another genuine model, breaking along three distinct planes that yield blocky pieces that resemble a rectangular box that has been twisted.  On the other hand, fracture is the propensity of a mineral to break along bended surfaces that don't have planes and break in a irregular pattern.

The thin segment of the nephron loop's descending limb ________. The thin segment of the nephron loop's descending limb ________
vovangra [49]

Answer:

The correct answer is ''aids in the passive movement of water out of the tubule''

Explanation:

The nephron loop has a descending branch, which goes to the renal medulla, and an ascending branch, which goes back to the cortex. The nephrons of these kidneys can have loops of Henle of different dimensions. The thin segment of the loop has thin epithelial membranes, its cells are highly permeable to water, but not to solutes. The water that exits from the descending portion of the nephron loop into the medullary space is immediately reabsorbed by the peritubular capillaries, causing osmolality to increase in both the tubular fluid and the medullary interstitial fluid. The characteristics of the descending branch differ from one species to another, the normal thing is that in one way or another, the osmotic concentration of the urine that moves through it is balanced with that of the interstitial fluid.

anzhelika [568]

Answer;

-Organizing the mitotic spindle in cell division

Explanation;

-A centriole is an organelle that helps cells divide, or make copies of themselves. Centrioles are only found in animal cells. All centrioles are made of protein strands called microtubules. Centrioles are made of nine triplets of microtubules arranged in a cylinder.

Describe an environmental factor that could influence natural selection and decrease genetic diversity
pashok25 [27]

Answer:

Usually, Populations have a genetic variation among individuals, which is important to the population's ability to survive in different situations that have an effect on the natural selection. There are different factors which can increase or decrease the genetic diversity, and influencing natural selection.

These factors include an environmental factor, one of the major factors, which may cause changes in the genetic variation of a population and influence the natural selection. A famous and important example of environmental factors affecting natural selection was during the Industrial Revolution, when many more grey moths made up the moth population.

This was so that they could blend in with the soot from factories to avoid predators.
