T. This is true because research is vital when it comes to diseases, infections, and other sicknesses. If the bacteria/viruses are strong enough and the treatments aren’t, they can become resistant to them. With research, we can develop a stronger treatment that will not be resisted by any bacteria/virus
Iodine solution is used to test leaves for the presence of starch. You need to: heat a plant leaf in boiling water for 30 seconds (this stops its chemical reactions) heat it in boiling ethanol for a few minutes (this removes most of its colour)
Answer:
sin a=-4/5
we have sina=perpendicularp/hypotenuseh=-4/5
let p=-4k
h=5k
by Pythagoras theorem
h²=p²+b²
(5k)²=(-4k)²+b²
25k²-16k²=b²
(3k)²=b²
b=√(3k)²=3k
now
cos a =b/h=3k/5k=3/5
Answer: Your senses are important because they work together to let your brain know what is going on around you. And they help to keep you safe by warning you of any danger. The way food looks not only entices you it actually affects they way you fell & act. For example diets high in refined sugars, for example, are harmful to the brain. In addition to worsening your body’s regulation of insulin, they also promote inflammation and oxidative stress. Multiple studies have found a correlation between a diet high in refined sugars and impaired brain function — and even a worsening of symptoms of mood disorders, such as depression.
