Answer:
The process shown in the model requires energy from the cell.
Explanation:
Active transport refers to the movement of materials across the cell membrane against concentration gradient.
The cell membrane remains intact. However, energy is required from within the cell to move materials into the cell against concentration gradient, hence the answer.
Answer:
Since curly hair is a dominant gene, there is a good likelihood that one or two curly-haired parents will produce a curly-haired cutie. But genetics are tricky, and there's a chance that two parents with curls could carry the straight hair recessive gene, and pass that onto their offspring.
Hope this helped you
Answer:
The reason the same expierament lead to different results is because the variable being expieramented on is not controlled
Explanation:
Controlled Variable
Experiments with faulty design or inconsistent data:
-decreases the experiment's reliability and validity
- wastes time and resources
- destroys the scientist's credibility in their field
- may lead to issues of safety to the experimenter/s due to faulty design
- is discouraged especially in hard sciences where data obtained should be accurate and precise
Explanation:
There are many<span> reasons that experiments with faulty </span>styles<span> or with incorrect </span>knowledge are<span> problematic for scientists. One reason for them to be problematic </span>is that if<span> he or she were to poorly </span>live<span> what </span>they're learning<span>. </span>as an example<span>, </span>somebody<span> measured the mass of a book </span>properly<span> to be </span>two<span> pounds, and </span>somebody else<span> measured it </span>erroneously<span> to be </span>one<span> pound. </span>differently<span>, that faulty designed experiments and inconsistent </span>knowledge will be<span> problematic is lack of accuracy and </span><span>exactness.</span>
