Frogs are vertebrate organisms.
Explanation: Frogs have vertebrae’s located in their backs so they definitely fall into the vertebrate animal class. Invertebrates don’t have such bones and usually use armored skin or muscles as structure such as octopus and crabs.
I believe the answer may be B) increased blood flow to the wounded area.
Answer:
The answer is A).
Explanation:
Based off <u>https://dlc.dcccd.edu/biology1-3/organic-molecules</u>, "In most organic molecules, a linked chain of carbon atoms forms a backbone to which other atoms attach. The unique number and arrangement of bonds between carbon atoms creates a structurally diverse set of organic molecules in nature."

They can use the temporary magnetic field it creates to pick p a metal clip.
<u>Explanation:</u>
When a copper wire is wound around an iron cylinder and current is passed through the wire, the wire wound cylinder acts like a magnet. It is known that a current carrying wire develops a magnetic field around it. This is the magnetic effect of electric current.
When the current carrying wire is wound around a cylinder it will become similar to a solenoid which is a device that continuously produces magnetic field on passing current through it.
The magnetic field will cease existing once the current supply is cut off and thus it is temporary.
Answer:
a. It is present at high concentration at the anterior end and low concentration at the posterior end.
Explanation:
One of the ways to define the anterior-posterior axis in Drosophila is by the products of the Bicoid and Nanos genes. The mRNA from the bicoid gene is transcribed by nurse cells. The bicoid mRNA is deposited in the unfertilized egg near its anterior pole. Therefore, the bicoid gene product serves as the anterior morphogen. The bicoid mRNA is translated after fertilization. The Bicoid proteins are present in higher concentrations at the anterior end and diffuse through the cell to create a concentration gradient from the anterior to the posterior end.
