Answer: The maximum number of amino acids that could be coded is 2
Explanation:
- A codon in this microorganism is 2 bases instead of 3 bases .
- In order to encode a protein a sequence requires a start and stop codon
- If you assume no start codon: then only 2 bases would make up the stop codon.
- This leaves 4 bases which is 2 codons. This would encode 2 amino acids.
- If you assume a start and stop codon, then each codon would be allocated 2 base pairs each = 4 base pairs
- This only leaves 2 base pairs, a single codon which would only code for 1 amino acid
The populations of the species there will go extinct
Answer:
occurring, awarded, or appearing after the death of the originator
Explanation:
B only in the nucleus and rough ER
Answer:
Kidneys : helps in forming urine
Ureter : They are connected to kidney and by peristaltic action transports urine from kidneys to bladder .
Urinary bladder : It is an hollow sac that holds the urine .
Urethra : transports urine from the bladder to outside of the body .
Explanation:
The human excretory system consists of : Kidney ,ureter ,urinary bladder and urethra .The figure is shown below .
Now , as far as functions are concerned we have :
Kidneys : They have excretory units called nephrons that further consist of :
- Bowman's capsule
- PCT (Proximal convoluted tubule )
- DCT (Distal convoluted tubule)
- CT (collecting tubule )
In nephrons urine is formed and via ureter it is transported to a hollow sac like structure called urinary bladder .
This bladder has muscles that cant remain contracted up to longer period )and then voluntary and involuntary it is excreted through urethra .
The process of passing urine is called Micturition .
