Answer:
Hypotonic solution
Explanation:
hypertonic solution is the one you get when the solute concentration of the water is higher than that of the cells.
isotonic solution is the one you get when the solute concentration of the cell and the water are the same.
hypotonic is the one that you get when the solute concentration of the cell is higher than that of the waters.
Solute concentration being low reminds me of water. Hypo kind of sounds like hippo and hippos love water. You can use this to memorize the difference between hypertonic and hypotonic solutions.
sorry if the grammer is bad i tried my best.
The mass extinctions that occurred 250 million years ago and 65 million years ago may have been due to gradual process or Catastrophic events.
Answer:
Explanation:
<em>The anatomy of a child's brains can be divided into three parts:
</em>
<em>
</em>
<em>- Cerebrum;
</em>
<em>
</em>
<em>- Brainserm;
</em>
<em>
</em>
<em>- Cerebellum.
</em>
<em>
</em>
- <em>The Cerebrum has the Cerebral cortex that is responsible for functions as coordination of movement, temperature, touch, vision, hearing, speech and language, judgment, reasoning, emotions and memory.
</em>
<em>
</em>
- <em>The Brainstem includes the medulla, midbrain, and the pons, being responsible for most of the involuntary movements.
</em>
<em>
</em>
- <em>The Cerebellum coordinate vonluntary muscle movements, and the balance of the body.</em>
<u><em>The part that stores the memory for a toddler as they are learning to walk is the cerebral cortex while the cerebellum coordinate and balance their movement to improve the walk with time.</em></u>

Answer:
D. Changes in the environment changed each morph's ability to evade predation in different ways.
Explanation:
The moth species<em> Biston betularia</em> has two color morphs, or variants. One has a speckled white and black color, while the other is all black. Over the period of time, the distribution of moths dramatically changed between 1900 and 1950 in such a way that black morph became dominant but speckled morphs became very much declined in abundance. The reasons behind this change was heavy industrial pollution in UK between 1900 and 1950.
When the environment became very polluted, dark and blackish, the speckled moth had more chanced of getting eaten by predators thats why they declined in number as compared to black morphs. On the other hand, backgrounds of grime and soot made black morphs less visible to the predators and they survived well. This is an excellent example of natural selection that only those specie better survive that have the ability to cope better with adverse environmental fluctuations.
Therefore, option D is best option.
Hope it help!
