Genes close to each other- Strongly Linked genes
Genes on different chromosome- unlinked genes
Genes apart from each other,but on same chromosome- linked genes
Explanation:
Linkage is defined as the tendency of genes located on same chromosome to be inherited together.
Genes located on different non-homologous chromosome are called unlinked genes.
Genes located on same chromosome are called linked genes.
Genes located close to each other are strongly linked as tend to show complete linkage.
Genes located on different chromosome tend to show incomplete linkage.
Pseudopodia is the correct answer.
Hope that helps!

The food supply of the carnivores in an ecosystem is the available herbivores, so in order for the carnivores to survive for an extended amount of time their population must be considerably less than their food supply, so that there is an abundance of prey available. Populations of predator and prey have a cyclic increasing and decreasing relationship to regulate the number of both.
Answer:
A. Mediator
Explanation:
Enhancers are cis regulatory sequences which are located very far - off from promoter sequence either upstream or down stream. They are capable of showing their impact even if they located far apart from promoter and Loop/Combinatorial model best describes the mechanism of action of enhancers.
The sequence of events are mentioned as under:
(1) First of all, activator binds to the enhancer;
(2) Co-activator which is also known as mediator binds to the activator;
(3) Chromatin remodelers bind with mediator at one end and heterochromatin on the other end so as to remove histones from heterochromatin and cause decondensation;
(4) General transcription factors (GTFs) bind the promoter;
(5) RNA polymerase II binds the promoter.
The enhancer forms a loop with the help of activator and mediator to reach near at promoter. In eukaryotes, activator does not interact with RNA polymerase directly, it interacts with the help of mediator so we can say that enhancer shows it's impact through protein-protein interaction.
