Fluke don't contain bones, while fins do. Flukes go fast while fins steer. Flukes also manage temperature control.
Answer: b - Chondroblasts within the cartilage divide and secrete new matrix
Explanation: Chondroblasts are derived from two sources; mesenchymal cells within the center of chondrification and chondrogenic cells of the inner cellular layer of the perichondrium (coverings that lie over most cartilage).
At the chondrification centers, the cartilage forming cells (Chondroblasts) begin to secrete the components of extracellular matrix of cartilage. As the amount of matrix increases, the Chondroblasts become separated from each other and they are located in small cavity within the matrix called lacunae.
Concurrently, the cells differentiate into matured cartilage cells called chondrocytes.
Answer:
Thick diameter, Myelinated
Explanation:
A alpha neurons conduct action potentials faster because of their large axon diameter and myelin.
- The large diameter is less resistant to the flow of ions and allows for faster conductivity.
- The myelin sheath is a layer of fat acting as to insulate the axon which helps increase signal conductance.
If the adjacent angles of a parallelogram measure 25° and 155°, the other two angles would measure 25° and 155°
<h3>What is a
parallelogram?</h3>
A parallelogram is a quadrilateral (has four sides and four angles) in which both sides are equal and parallel to each other. Opposite angles of a parallelogram have the same measure and the diagonals are equal in length.
If the adjacent angles of a parallelogram measure 25° and 155°, the other two angles would measure 25° and 155° because opposite angles are equal.

Skeletal mass increases dramatically during childhood and adolescence, and decreases dramatically at the beginning of the fourth decade of life and decreases with age, with an exception of the skull.
Hope this helps! Have a BLESSED day! :-)
