Answer:
According to the image, the approximate QT interval is 0.4 seconds.
Explanation:
The QT interval is the space between the beginning of the QRS complex and the end of the T wave, which represents from the beginning of depolarization to ventricular repolarization.
Considering that the extandardized measurements of an EKG, where the paper circulates at a speed of 25 mm/s, 1 mm horizontal —measuring time— has an equivalence of 0.04 s.
In the image, there is 10 mm between the beginning of the QRS and the end of the T wave, so:
0.04 seconds X 10 mm = 0.4 seconds.
Then, the estimated QT interval is 0.4 seconds.
All of them are correct soil erosion turns grains of soil into mere grains of sand which when placed in water makes the water much cloudier, biodiversity will decrease as soil erosion leads to a more Barron and dry landscape, respiratory disease may be caused by inhaled particles of dust which can be create from soil erosion, and desertification as mentioned earlier soil erosion leads to a more baron and dried out landscape as the soil can’t hold water as much as it used too.
Answer:

Explanation:
If you are talking about adapting to an environment then yes, like how we train to strengthen our muscles to get stronger. If you mean by evolving then no, a single organism can not evolve their traits in a lifetime, like a human can't naturally grow gills to breathe underwater
Answer:
C. Water
Explanation:
The cells in our bodies are full of water. The excellent ability of water to dissolve so many substances allows our cells to use valuable nutrients, minerals, and chemicals in biological processes. Water's "stickiness" (from surface tension) plays a part in our body's ability to transport these materials all through ourselves.
