Serous membranes line certain cavities within the anterior body cavity. This statement is FALSE.
Serous membrane, also known as serosa in anatomy, is a silky tissue membrane made of mesothelium that lines the interior of bodily cavities and their contents. It secretes serous fluid to permit greased sliding motions between friction surface. Organs housed in body cavities that don't open up to the outside are covered by serous membranes that line the body cavities. The epithelium secretes a thin coating of serous fluid that coats serous membranes.
An indication of a serous membrane is the lining of the thorax. The pleura is the name for the serous membrane found in the thorax. The visceral pleura, the innermost layer, is on the lungs, whereas the parietal pleura, the outermost layer, is on the interior layer of the thorax.

Hey there! :)
To solve a Punnett square, we need to master the fields in the attached picture
In the question, the given keys are:
Dominant allele Y → yellow
Recessive allele y → green
Y | y Y | YY Yy Y | YY YyThis would be the Punnett square for this question
Percentage of offspring to have yellow seeds?
Yellow is Y, then we should count which alleles had YY as a genotype?
YY = 2 out of 4, then
50%
<span>Answer: 16 combinations
A fruit fly has four pairs of chromosomes in its cells. Assuming all pair is heterozygotes, each pair of the chromosome can be divided into two possible combinations. So, if there are 4 pairs then the possible combination would be 2 * 2 * 2 * 2= 16 possible combinations.</span>
I say about 40 percent cause say something like this ..
20% of small species of fish
20% of big species of fish
to be equal
20% are bigger
20% are smaller
hoped this helped ! <u />
