1. gravitational potential energy
Yes, motion energy (kinetic energy) is transformed into gravitational potential energy as the rock falls.
2..When we push a huge rock, there is no transfer of muscular energy to the stationary rock. Also, there is no loss of energy because muscular energy is transferred into heat energy, which causes our body to become hot. From the conservation of energy we know that energy can neither be created nor destroyed, it can only be transformed from one form to another.
3 When the rock starts rolling down the hill it has kinetic energy. When the rock gets to the bottom of the hill and stops, it is no longer in motion therefore it no longer has kinetic energy, the energy has been converted back into potential energy.
Potential energy is transformed to kinetic energy.
Answer:
c) Alternative splicing
Explanation:
Eukaryotic genes have protein-coding sequences called exons and non-protein coding sequences called introns. Introns are removed from the primary transcript after transcription. Some sequences may serve as both introns and exons. These sequences may be removed as introns or may be retained as exons producing mRNA with different combinations of exons from the single primary transcript. The process of called alternative splicing and allows the formation of more than one mRNAs from a single gene.
Therefore, alternative splicing allows one protein-coding sequence to code for more than one type of related proteins. It does not allow to correlate the number of protein-coding genes with the total number of proteins produced by a species.
Answer:
I) Nematodes lack body cavity
II) Nematodes are cylindrical but not segmented
Explanation:
The unknown creature is a nematode, and not an annelid once it has the following characterictics
- Absence of body cavity
Unlike annelids, Nematodes lack true body cavity but possess a pseudo-coelom body cavity
- Unlike annelids with cylindrical and segmented bodies, nematodes are cylindrical but not segmented.
Examples of nematodes are guinea worms, thread worms etc; while examples of annelids are earthworm and leeches.
The scrotum reacts to temperature. When it is cold, the scrotum shrinks, pulling the testes against the body to keep them warm. When it is hot, the scrotum relaxes, lowering the testes away from the body. This contractile ability of the scrotum can either raise or lower the temperature of the testes by a few degrees, ensuring that the optimum temperature for sperm production is maintained.
Hey there,
Question: <span>What differences can you see when you compare the nucleus of a dividing cell with that of a non-dividing cell?
Answer:
1) A dividing cell 's nucleus has visible chromatin. But the non-dividing cells chromatin is not visible
2) Chromosomes will be seen in the nucleus of the dividing cell but not in the non-dividing cell
Hope this helps :D
