Generally, epithelial cells serve the function of protection of the inner layers of the structure they are on. The fact that these columbar epithelium and transitional epithelium cells have smooth walls and are dome shaped allows them to stretch. This stretching helps the bladder retain more urine than it would be able to if the epithelial cells were rigid.

Explanation:
a hydrophyte is a plant that thrives only in or on water, such as the common lilly pad while a xerotype is a plant that makes adaptations to survive with very little water such as a cactus
Answer:
a poster showing the steps involved in photosynthesis
Explanation: Photosynthesis is a very necessary process on the earth surface. Photosynthesis is a process in which energy is produced. In this process, carbondioxode enters through small opening called stomata and water is absorbed by the plant from the soil. When these two are combine with each other in the presence of sunlight, it produces glucose and oxygen.
Answer:
C - Contains the embryonic disk
Explanation:
After an egg is fertilized, it begins to divide into smaller cells, from the 1 cell stage, to 2, to 4 and so on. Then, on the third day, the cells fall within 16-200 cells and it is then called a <em>morula</em>.
On the fifth day, the morula becomes a ball of calls which is now differentiated into an <em>inner cell mass and a trophectoderm</em>. The inner cell mass becomes the <em>embryo</em> as development goes on and the trophectoderm, becomes the <em>placenta</em>.
As development goes on further, the floor of the amniotic cavity is formed by the embryonic disk, a layer of prismatic cells derived from the inner cell mass.
The embryonic disc develops into 3 layers:
There is a major differentiation of cells which gives a template for the origin of development of specific organs of the embryo.
Since the colorblindness is located on the X chromosome, the man must have inherited his colorblindness from his mother.
<h3>X-linked traits</h3>
Women are XX while men are XY.
Also, the X chromosome in XY always comes from the mother.
Since the man is affected for colorblindness but his brother is not, it means that only one X chromosome of the mother is affected while the father can be affected or otherwise.
Assuming the father is free from colorblindness and the allele is represented by c:
x 
Thus, the man's genotype is and it comes from the mother.
