Hello. This question is incomplete. It is important that you always provide all the information so that your question can be answered the way you deserve.
The full question is:
"Which of the following has the element correctly matched with its description?
The duodenum is the first section of the small intestine and contains Peyer's patches.
The bile moves upward and backward and pushes the bolus
The bones attaches the liver to the anterior abdominal wall
Tongue toxins prevent water absorption in the large intestine"
Answer:
The duodenum is the first section of the small intestine and contains Peyer's patches.
Explanation:
It is true that the duodenum is the first section of the small intestine where Peyer's patches are located. The duodenum is the place where most of the entire digestive process occurs, in addition, it allows food to mix with bile and digestive juices.
Peyer's patches play an important role in immunological surveillance during digestive processes. This is because it allows the destruction of possible pathogens associated with food, or that interfere with digestion in some way.

Answer:.
A test-cross can reveal an unknown genotype. As the plants are heterozygous they sort independently of each other. when they are cross linked dominant genes express themselves in most of the cases whereas the recessive genes also express themselves resulting in the formation of tall and yellow plants and as well as short and green plants.
Explanation:
The impact of a single gene on more than one characteristic is called pleiotropy. Mendel deduced from his results that each individual had two discrete copies of the characteristic that are passed individually to offspring.Mendel called the dominant allele the expressed unit factor; the recessive allele was referred to as the latent unit factor.Mendel’s law of dominance states that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. The recessive trait will only be expressed by offspring that have two copies of this allele and these offspring will breed true when self-crossed.
Answer:
Gene knockout is a technique used to determine the function of a gene that has already been sequenced, which is achieved by analyzing the phenotype of the individual carrying the knockout mutation(s). Moreover, gene sequencing is a technique used to determine the sequence of a given gene, which allows to determine how gene variants (polymorphisms) may be associated with the phenotypes of the target trait.
Explanation:
In genetics, gene knockout is a technique used to trigger mutations in a (already) sequenced gene in order to inactive its function and observe the resulting phenotype for a particular trait. This approach that starts with the inactivation of a given gene and ends with the phenotype is known as reverse-genetics. On the other hand, gene sequencing can be defined as the methodologies/techniques/tools used to determine the nucleotide base pair sequence of a particular gene. The gene knockout technique involves knowing a priori the gene sequence in order to obtain a gene knockout (gene KO). The combination of the information obtained from these techniques can be used to determine how variation (genetic variation) affects the expression of a phenotypic trait.
