Answer:
19 gram of molecule are present in NaOH
Explanation:
because of 10 gram we put in NaOH it is incomplete if we put 9 gram in NaOH it is complete NaOH =11+8+1 =19
Answer:
The correct answer would be C. ³⁵S has more neutrons than ³²S; Hershey and Chase used it because it is radioactive and can be easily traced.
Sulfur-35 (³⁵S) is one of the isotopes of the sulfur which has 16 protons (same as sulfur-32) but 19 neutrons as compared to the 16 neutrons of sulfur-32.
It is a radioactive isotope which breaks down by beta-decay and gets converted into ³⁵Cl.
They used ³⁵S for radioactive labeling of the protein coat of the bacteriophage. It helped them to trace the movement or transfer of protein efficiently.
Answer:
Metamorphic rocks are almost always harder than sedimentary rocks. They are generally as hard and sometimes harder than igneous rocks. They form the roots of many mountain chains and are exposed to the surface after the softer outer layers of rocks are eroded away.
Because their mineral grains grew together tightly during metamorphism, they're generally strong rocks.
Answer:
The first one
When pulling a tree from the ground
Answer:A good index fossil is one with four characteristics: it is distinctive, widespread, abundant, and limited in geologic time. Because most fossil-bearing rocks formed in the ocean, the major index fossils are marine organisms. That being said, certain land organisms are useful in young rocks and specific regions.
