Starfish can sometimes be predators to snails. Starfish are marine invertebrates, and they can regenerate injured or amputated limbs. Although starfish have no brain or blood, females are capable of producing up to 65 million eggs at once.
Snails a<span>re gastropod mollusks, and the average garden snail only produces about 80 eggs at once. </span>

Mama L [17]

Answer:

There are 4.28×10^10 RBCs in the blood sample.

Explanation:

Concentration of blood = 5×10^6 RBC/10^-6 L = 5×10^12 RBC/L of blood

Volume of blood sample = 8.56 mL = 8.56/1000 = 0.00856 L

Number of RBCs = concentration of blood × volume of blood sample = 5×10^12 RBC/L × 0.00856 L = 4.28×10^10 RBCs

A particular triplet of bases in the template strand of DNA is 5' AGT 3'. The corresponding codon for the mRNA transcribed is __
earnstyle [38]

Answer:

The correct answer is 3' UCA 5'

Explanation:

The rule of pairing of base-pair says that A and T base pairs with each other with two hydrogen bonds and G and C base pairs with each other with three hydrogen bonds in DNA. In the case of RNA Uracil comes at the place of thymine that means uracil replaces thymine.

Therefore according to this base-pairing rule the corresponding codon of mRNA transcribes from DNA codon 5' AGT 3' will be 3' UCA 5' as U came in place of A nucleotide, C comes in place of G nucleotide, and A comes in place of T nucleotide.  

Therefore the correct answer is 3' UCA 5'.

Then, at the end of the axon called a synapse, chemical substances called neurotransmitters get released to transmit the message. These neurotransmitters then attach to chemical receptors in the following neuron.
