Answer
Hi,
A. Radioactive markers
Explanation
Hershey and Chase used specific radioisotopes to form a trace of the two important components of the virus in its life cycle. The 32P was used to identify the DNA while the 35s labeled the proteins.DNA strands have a sugar phosphate where as protein contains sulfur.
Best wishes!
Answer:
Translocation
Explanation:
Sometimes a piece of chromosome will attach onto a different, non- homologous chromosome that has also lost a piece.
The correct steps of endochondral ossification is:
- A periosteal bone collar develops.
- spongy bone and the medullary cavity form in the diaphysis.
- The diaphysis center is vascularized and osteoblasts deposit osteoid over calcified cartilage matrix.
- The epiphyseal center is vascularized and osteoblasts deposit osteoid over the calcified cartilage matrix.
- The spongy bone forms in epiphysis.
<h3>Which bones grow by endochondral ossification?</h3>
Long and short bones, such as the phalanges and femur, arise from a cartilage model formed by endochondral ossification. Distinguishing between these two types of osteogenesis does not imply the existence of multiple types of bone tissue.
Endochondral ossification mainly forms in two stages: modifications of the hyaline cartilage that ends with the death of chondrocytes and invasion of osteogenic cells and their differentiation into osteoblasts in the cavities previously occupied by chondrocytes for deposition.

Answer:
so that the genetic variations are not directly exact
Explanation:
Answer:
In this experiment, you changed the number of worms in the soil and measured the effect of this change on the plant growth in the population.
The independent variable was the number of worms, and the dependent variable was the plant growth.
