Answer: a. increased energy efficiency

Explanation:

Ahat [919]1 year ago
3 0

Answer:

a) increased energy efficiency

if you consider it, increased energy efficiency is also helping to produce <em>positive </em>changes in the global climate

(increased resource use means an increase of the use/removal of naturally occurring materials [it messes with water, soil, wood, animal, etc.] and is <em>not </em>a benefit of scientific advancements)

increased urbanization isn't an objective benefit [and it is not contributed to by scientific advancements]

so, scientific advancements have increased energy efficiency

(a few examples):

- we've invented new ways to harvest energy [solar, nuclear, wind, etc.]

- better operated / more resourceful inventions (we've replaced a lot of very wasteful [mainly car] engines)

hope this helps!!

What do we mean when we refer to a cell as differentiated?
Otrada [13]

Answer:

We mean that a cell changes to another type of cell.

Explanation:

<em>Stem cells </em>are a type of cell that has the potential to become a specialized cell, this change or differentiation, is possible thanks to the activation or deactivation of certain genes that promote (or inhibit) the expression of certain proteins that origins different types of cells (fmuscle cells, osteocytes, neurons). This differentiation happens when the cells receive cues internally ( through signals or contact between a group of cells and another or through transcription factors) or externally.

Then, a differentiated cell is a cell that had gone under the previously described process.

I hope this information is useful to you!
