What factors are considered to determine if something is moving?

1 answer:

8 0

An object is in motion if its distance relative to another object is changing. To tell if an object is moving, you use a reference point. If an object's distance from another object [reference point] is changing. A place or object used for comparison to determine if something is in motion.

I'm not too sure if this is what you needed go know, I hope it helped

Following a bone fracture, the body must repair bone tissue by producing new bone cells. What is the source of these new cells?

LiRa [457]

Answer:

The periosteum is one source of precursor cells which develop into chondroblasts and osteoblasts that are essential to the healing of bone. Other sources of precursor cells are the bone marrow (when present), endosteum, small blood vessels, and fibroblasts.

Why is recombinant dna also referred to as genetic engineering?

aev [14]

Recombinant DNA is DNA that has been created using intelligent design methods to modify a base DNA molecule using DNA component elements from other strands of DNA of other organisms. There are a wide range of possible DNA elements that can be removed, added to or otherwise modified to produce the new recombinant form.

Recombinant DNA technology clearly is genetic engineering using intelligent design as the selection and placement of the added DNA components must be planned and precisely selected and placed to accomplish the intended result. It does not happen naturalistically.

There are numerous aspects of the growing technology of recombinant DNA that modify DNA to serve the purpose of the intelligent designers, including wide ranges of research, medicine, synthetic biology, potential commercial products and even scientific curiosity.

andriy [413]

Answer:

The correct answer is B. the two strands of DNA must separate.

Explanation:

DNA is a double-stranded structure. The two strands are joined together by the formation of hydrogen bonds between complementary nucleotides. So before the replication takes place these two strands must be separated.

The separation of DNA strand is accomplished by the action of a helicase enzyme which breaks the hydrogen bond between complementary nucleotides and separated the two DNA strands.

After separation, the DNA polymerase binds to separated DNA and replicating the DNA. So the right answer is B.
