- Complex carbohydrates are made up of sugar molecules that are strung together in long, complex chains. Complex carbohydrates are found in foods such as peas, beans, whole grains, and vegetables. Both simple and complex carbohydrates are turned to glucose (blood sugar) in the body and are used as energy.

Answer:
The correct answer is - Anaphase.
Explanation:
Cell division can be either mitosis or meiosis. Mitosis cell division has these phases:
A. Interphase - non-dividing phase with to G1, S and G2 sub phase. In this genetic material doubles and cell size increases.
B. Prophase- chromosomes shorten and condense by coiling. Centrioles move in opposite directions.
C. Metaphase - spindle fibres bind to kinetochores and pulls it the chromosomes on the equator of the spindle forms a plate called the metaphase plate.
D. Anaphase- these get condense and centromeres split into two and the spindle fibres pull the daughter centromeres to opposite poles.
E. Telophase is the last phase of Mitosis.
Answer: Option A.
Different beaks were available
Explanation:
Variation is the difference between traits, cells, or characteristics between organisms of any species which is caused by change in genetic information or effect of environmental factors on the expression of genes.
From the question, different beaks were available because there is variation or differences in shapes, sizes and expression.
Answer:
In which class of elements is there a greater range of properties, the metals or the nonmetals? Give an example to support your answer. Non-metals have greater range of properties given that they exist as solids, liquids and gases. And also that they can polymerize, crystallize and form organic compounds.
Answer:
DNA from a gene of interest can be inserted into a plasmid, then the modified plasmid can be inserted into a bacterial cell to replicate a gene of interest many times.
Explanation:
Plasmids are the extra-chromosomal circular DNA present in bacterial cells. Plasmids are able to replicate themselves independent of genetic DNA. Their ability to self replicate allows them to maintain themselves in the bacterial cells. This is why plasmids are used as cloning vectors in recombinant DNA technology.
A gene of interest is isolated from the donor cell and is inserted into the plasmid. The recombinant plasmid is introduced into bacterial cells where it replicates the ligated desired gene and allows the gene cloning. For example, the human insulin gene is ligated with plasmid and the recombinant plasmid is introduced in <em>E. coli</em> where it replicates the human insulin gene and allows the production of desired copies of the gene.
