Answer:
1. TEF
2.RMR
3.TEA
Explanation:
The major components that contribute to the body daily expenditure are as follows
1. TEF(Thermal effect of feeding)
2.RMR( Resting metabolic rate )
3.TEA(Thermal effect of activity)
Generally resting metabolic rate consume 60 to 75% of energy for maintenance thwe body temperature.
When body is doing this some physical work then it is called activity related expenditure.
Answer:
It indicates that core histone genes were present in the last common ancestor of yeasts, plants, and animals
Explanation:
Histones are highly basic proteins that can strongly interact with DNA, which is packaged into nucleosomes, the basic structural and functional unit of chromatin. Each nucleosome is composed of approximately 147 base pairs of DNA wrapped around a core of eight histone proteins (two copies of four types of histones H3, H4, H2A, H2B). These core histones are evolutionarily conserved across eukaryotic kingdoms in terms of sequence and structure. Therefore, DNA-packaging into nucleosomes is considered a constraint for the evolution of core histones. Moreover, the presence of conserved core histones in eukaryotic kingdoms (e.g., yeast, plant, and animal kingdoms) is strong evidence that histone-mediated DNA packaging was presumably present in the last common ancestor of eukaryotic genomes.
the answer could not be D because a Golgi Apparatus is a tiny structure, or organelle, in a cell that "packages" nutrients for use inside the cell. The answer could not be c. because a nucleus is a tiny structure, or organelle, in a cell that "packages" nutrients for use inside the cell. The answer could not be Endoplasmic Reticulum because that is where proteins are transported from one part to the other. So the only answer left is Mitochondria, because the Mitochondriamain function is to produce ATP, the energy currency of the cell.
First helicase separates the two strands of DNA and then DNA polymerase adds nucleotides following the base pair rule.
