Hi,
There are 10 significant digits in the measurement of <span>9478.983560 cm. A significant number is a number that is not a zero, however, in this problem you see there is one zero and that counts as a significant number because it is after a whole number.
In conclusion, a significant number is a number that is not a zero, however the only exception to this rule is that it must be after a whole number for it it to count as significant.
Thanks a lot for posting and I hope this helped. :)

Answer:
A ciliated secretory epithelium lines the uterine tube.
Answer:
d. smooth endoplasmic reticulum
Explanation:
Organelles are structures found in inside the cell which carries out a specific function. Types of organelles include endoplasmic reticulum, Golgi body, ribosomes, nucleus etc. The function in the question is protein synthesis.
Ribosomes are the sites of protein synthesis in the cell of living organisms.
- The nucleus is involved in the synthesis of protein because it directs all the cellular processes in a cell including protein synthesis.
- Rough endoplasmic reticulum (RER) is a type of endoplasmic reticulum whose surface is attached to by ribosomes, hence, giving it its rough surface. Since ribosomes (organelle for protein synthesis) are attached to the RER, the RER are involved in protein synthesis.
- Golgi bodies are organelles that functions to package, process and sorted the proteins produced in the ribosomes.
- The smooth endoplasmic reticulum (SER) are NOT involved in the synthesis of protein because they have no ribosomes attached to their surface. Instead, they are involved in lipid synthesis.
Growth factors are cell-surface receptor-binding proteins that encourage the growth and development of target cells.
<h3>What is Growth Factor ?</h3>
A growth factor is a naturally occurring chemical that promotes cell proliferation, wound healing, and, on rare occasions, cellular differentiation. It is usually a secreted protein or a steroid hormone. Growth factors play a crucial role in the regulation of many cellular processes.
- A growth factor is a protein that stimulates the growth of specific tissues. Growth factors are found in a wide variety of animals, including insects, amphibians, humans, and plants, and they serve a crucial role in encouraging cellular differentiation and cell division.
- Growth factors are commonly used as a signaling molecule between cells. Cytokines and hormones, for example, attach to specific receptors on the surface of their target cells. As a result, the correct answer is proteins that bind to surface receptors and excite target cells.
Growth factors are local regulators that - bind to cell-surface receptors and stimulate growth and development of target cells.
