Answer:
1. vi. Preganglionic
2. vii. adrenergic
3. ii. sympathetic chain ganglia
4. iii. Craniosacral
5. viii. splanchnic
Explanation:
Action potential travel down preganglionic nerve fibre. They travel towards Vagus Nerve near the effector organ. These impulses arrive at cardiac plexus, which create action potential in postganlianic.
Answer:
implantation – the process by which the zygote attaches to the uterine wall.
This would be an example of negative feedback because the body isn’t trying to surpass a set point. It’s trying to maintain the amount of food in the stomach at that point.
Answer:
C) no, the final mRNA contains only exons, the introns were removed
Explanation:
Exons are the coding areas while the introns are non-coding areas. Both of these are the sequences of nucleotide within a gene.
RNA splicing is a process which usually occurs as the RNA matures, causing the removal of introns ( non coding areas of the RNA ) i-e they will not be expressed in the final messenger RNA, while exons continue to form covalent bonds with one another to form a mature mRNA.
So in the given scenario, Upon comparison, the mRNA is found to contain 1,000 fewer bases than the DNA sequence because the introns were removed by RNA splicing.
Hence option C) no, the final mRNA contains only exons, the introns were removed is correct.
Answer:
02.5 N
Explanation:
02.5 N is a derived unit of measurement.
A derived unit is one that is obtained by combining two or more fundamental units.
Force = mass x acceleration
The unit of mass = kg
acceleration = m/s²
Combining the two; kg x m/s² = kgms²
1N = 1 kgms²
kg, m, k and N are fundamental particles
