Answer:
E. Mangroves have only one type of root system
Explanation:
Mangrove species are those species of plants found in a saline environment. The soil they are found is usually shallow and swampy (water-logged). They possess characteristics feature that helps them adapt and survie in their habitat.
One of those features is the possession of PNEUMATOPHORES OR BREATHING ROOTS, which is a kind of root system that extends out so that the pores on them can allow the intake of gases directly from the atmosphere.
Answer:
-Because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.
-The diverse proteins found in and attached to membranes perform many important functions.
-The framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.
Answer:
the job of the tRNA is to read the message of the nucleic acids or nucleotides and translate it into proteins or amino acids . it translates the mRNA. gives the Ribosome directions on what kinds of proteins to make
Explanation:
The answer is repolarization. In the first phases of an action potential,
Sodium ions flow into the cell, through the voltage-gated ion channels, causing depolarization from the resting potential of -70 mV. In the later stages of the action potential, the potassium ion selective filter channels open and potassium ions move from inside of the cell to the outside. This repolarizes the cell before sodium ions begin to be pumped out of the cell.
This is the DNA. I'm going to only use the upper strand to demonstrate what this strand would code for before and after a single bp deletion (so write it as mRNA). I will also write it how it's easier to see this which is to split them up into the 3 base codon system. Note that you don't need to know the amino acid code - you use a table to find these.
ORIGINAL (mRNA on top, Amino Acid (AA) on bottom:
5'-AGC GGG AUG AGC GCA UGU GGC GCA UAA CUG-3'
SER GLY MET SER ALA CYS GLY ALA STOP LEU
Note that the protein would stop being made at the stop codon and the LEU wouldn't matter at the end...
Now, I will remove one bp...(I bolded it up top). Rewrite the mRNA and find the corresponding AA...
NEW
5'-AGC GGG AUG GCG CAU GTG GCG CAU AAC UG-3'
SER GLY MET ALA HIS VAL ALA HIS ASN .....
Completely different amino acid sequence after the methionine (MET). The stop codon is gone...the protein would continue being translated until it reaches another stop codon...so not what was supposed to be made!
