Answer:
Option A, most closely related to mammals
Explanation:
Insects like arthropods and molluscs have an open circulatory system and thus do have a distinguishable heart. Fish has two chambered heart. Reptiles have three chambered heart. Amphibians too have a three chambered heart.
All mammals and fish have four chambered heart. The right and left sides of the chambers have restricted entry and hence remain intact from each other
Hence, option A is correct
It’s all in socratic because i did that already and it was really easy
Answer:
Parasympathetic nervous system effects are slow or inhibit function, where is sympathetic, is responsible for the intense physical activity.
Explanation:
The autonomic nervous system or ANS is divided into 2 distinct systems on the basis of their effects- the parasympathetic nervous system and the sympathetic nervous system.
Both of these have opposite actions on the functions that they maintain.
The sympathetic nervous system regulates the body for a high level of physical activity and also known as fight or flight. It fasts the functions of the body according to the situation.
The parasympathetic nervous system is having the opposite effect of the sympathetic nervous system slows high energy functions and relaxes the body.
Thus, the comparison of these nervous systems is mention above.
Aspartate + a- keto acid >> Oxaloacetate + a amino acid
This reaction is occur because the a- keto acid in the equation can come from any amino acid, the 15 N from aspartate is rapidly transferred to other amino acids.
15N is symbol use as the isotope of nitrogen with mass number 15. comprises of 0.4 % of stable nitrogen found, so the relative abundance of each in amino acid is simply a reflection of how much is found in nature in general.
This isotopes is enrichment of the labelled amino acids was determined following a previously developed procedure comprising by determination of the spectral purity of the selected natural abundance amino acids.
