Growth factors are hormones, proteins, or steroid molecules that regulate many cellular functions. They can stimulate the cell division by giving the signal to the cell to progress in the cell cycle.  

<u>Explanation</u>:  

Growth factors are naturally produced within the body and travels through the body to bind to their receptors present on their target cells. These growth factors are capable of signalling the cell to divide, proliferate, or heel. Their main aim is to signal or tell other cell when to do and what to do. Due to the binding with the receptors the growth factors activates specific genes.

How are cells with monosomy different from haploid cells
gladu [14]
Haploid refers to a cell that has has only one copy of each chromosome, like in a gamete such as a sperm cell or egg cell. Upon fertilization, the two haploids come together to form a full diploid cell (two copies of each chromosome) which then goes on to form the complete organism. Monosomy refers to a condition where there is only one copy of a specific chromosome. For example, in the human condition Turner Syndrome, there is only one X chromosome, instead of two sex chromosomes. Most incidences of monosomy other than Turner Syndrome are lethal, so there aren't many examples of it.

Question 1
weqwewe [10]

The correct statement is D. The mental region is superior to the nasal region.

The different terms in the statements are anatomical terms. We use them to describe the regions and locations of organs.

<h3>Why are the other statements incorrect</h3>
  • The pubic region is inferior to the pelvic region: inferior means is lower. However, the pubic region is higher than the pelvic region.
  • The olecranon region is distal to the carpal region: we describe organs and bones in relation to the nearest parts to the axis of the body. In other words, we describe things from proximal (to the column and head) to distal. So, the carpal is distal to the olecranon.
  • The heart lies dorsal to the vertebral column: dorsal means behind. The heart lies ventral to the column. In other words, towards the front of it.
  • The sternal region is lateral to the axillary region: we describe locations from proximal to distal, so the axillary region is lateral to the sternal region.

In conclusion, the correct option is: The mental region is superior to the nasal region because the mental region is the one that is above the nasal one in the skull.
