I'm guessing sporophyte. I know mosses are nonvascular (they don't conduct their own food or water). They go through haploid and diploid phases. The haploid phase is most prominent in mosses.
Sorry if this isn't helpful.
The gall bladder is composed of the following major tissues.
The epithelium
This is the layer found innermost in the gall bladder.
Submucosa
This is a thin layer of tissue composed of loose connective tissue.
Smooth Muscular tissue.
This tissue forms a muscular layer in transverse, oblique and longitudinal directions and these muscular tissue contracts to expel bile from the gall bladder.
Perimuscular tissue
This is a tissue that is fibrous in nature and is a connective tissue.
Serosa
This is quite a thick layer of tissue. It covers the gall bladder's outer surface . It contains lymphatic network, nerves and large blood vessels .Where it is connected to the liver it is known as adventia. In the region that is not attached there is found an outer layer of loose connective tissue (serosa) and another kind of tissue known as mesothelium.
Mutations acquired by somatic cells are generally only retained by the individual they acquire in as there is no vector by which to transmit the mutation.
<span>Between generations, the only mutations that may be transmitted are those already acquired from a parent, and those that occur within the individuals own germ cells. If mutations in the germ cells result in sperm or eggs that contain that mutation, then they may be transmitted to their offspring. </span>
<span>Red blood cells in all humans and other mammals, though, don't contain nuclear DNA and as such cannot acquire mutations.</span>
Missing options:
A) the formation of recombinant DNA
B) the synthesis of a different polypeptide
C) crossing-over
D) polyploidy
Answer:
B) the synthesis of a different polypeptide
Explanation:
The statement highlights a change in the codon sequence from UCG to UGC. If we look at the table of amino acids, we would realize that UCG encodes for "<u>Serine</u>" whereas UGC encodes for "Cysteine" amino acids. This single change in DNA sequence is known is <u>mutation</u> or <u>single nucleotide polymorphism (SNP)</u>. Finally, the change in amino acid will result in the synthesis of a different polypeptide which contians a different amino acids. See figure attached for codon table.
