The main reason for the difference in the mass extinction occurring today and previously is the pace of the current extinction. The extinction is taking place globally and involves hundreds of species at the same time. In less than 50 years, we have lost numerous species. In contrast to this, previously during the mass extinction, only a few species were lost, and other managed to survive. But, not the status is opposite due to the magnitude of the extinction.
The area is called the anterior fontanel and closes anytime between 9 and 18 months of age.
The answer is A) less than 2.9
Answer:
Ribosomes
Explanation:
This is the organelle for regulating protein synthesis in cells.It is made up of the small and big submits. These sub units collectively ensure the process of translation of protein my ensuing the correct synchronisation of condoms not he smaller nit of ribosomes with the anti codons on the tRNA with the to give a designated protein.
Therefore if there is mutation -deletion or substitution in the codons and anti codons,.this may affect bring frame shift which affects the protein translated leading to wrong protein formation.
Mitochondria is the organelle that gives the sperm power to swim.Therefore the protein that codes for mitochondrial is faulty and this affects the the tail from swimming properly.since ribosomes is the source of protein this is the correct answer
