Answer:
4900 J
Explanation:
Potential energy is the product of the mass, gravitational constant and the height of the object.
U=mgh=10 kg×9.8 m s^(-2)×50 m=4900 J
So, the potential energy of the object is 4900 J.
Answer: The correct option for the fill in the blank is B) Transcript, ribosome.
mRNA is formed by a template of DNA in the nucleus of eukaryotic cells. The genetic information from DNA is transferred to mRNA in process called Transcription. mRNA is transported outside nucleus and helps in protein synthesis at the site called ribosomes.
mRNA thus carries a transcript of DNA instruction out of the nucleus. It helps in the formation of synthesis at ribososme ( present in the cytoplasm of the cell).
Thus, option B) is the right answer.
Answer:
at its typical resting length.
Explanation:
Muscle fibers are elongated cells that can have one or more nuclei. They will form muscle tissues, which can be of three types: striated cardiac muscle, skeletal striated muscle or smooth muscle, each having its own functional and morphological characteristics. However, these types of muscle fibers have in common the ability to generate movement by contraction.
Contraction occurs at the moment of maximum tension of these muscle fibers and a muscle fiber develops its maximum tension when it is at its typical resting length before being stimulated.
Cell division, also called mitosis , occurs in multicellular organisms to create tissues, organs and organ systems.
