Answer:
They live in fresh water, marine or soil. They feed off of bacteria and other protozoa.
Explanation:
Mendeleev organized the chemical elements based on their properties.
Mendeleev put elements in order in the periodic table according to their physical and chemical properties. He noticed that properties of elements were related to their atomic mass in a 'periodic' way, so he groups of elements with similar properties into vertical columns in the table. His periodic table had initial 63 elements which then expanded to 108 or 109 elements.
well it is not exactly essentioal but salmon need it
B = adds nucleotides
A = unwinds the DNA
C= joins Okazaki
D = tells where to build
Answer: Her acceleration is -0.8 m/s²
Explanation:
The initial velocity of Sandra ( u) = 10 m/s
The final velocity of Sandra ( v) = 2 m/s
Time taken by Sandra (t) = 10 s
Let the acceleration of Sandra be 'a'
Using the equation of kinematics, we have
v = u + at
⇒ 2 = 10 + 10a
⇒ -8 = 10a
⇒ 
⇒ a = -0.8 m/s²
Hence, her acceleration is -0.8 m/s².
