Answer:

Actually, The reaction is chemical and endothermic. Chemicals A and B form an endothermic reaction, and chemicals C and D form an exothermic reaction. Therefore, chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

Answer:

Bond breakage and reformation.

Explanation:

<em>During chemical reactions, atoms within the participating reactants are rearranged. These rearrangement occur as a result of breaking and reforming of bonds.</em>

When the bond holding the atoms within a particular reactant is broken, it cannot reform except if the reaction is a reversible one. New bond are formed between atoms of different reactants.

vince stains dna with a dna-binding dye. what suborganellar structures will become visible after staining?

Basile [38]

The suborganellar structure that will become visible after staining is nucleoid.

In the field of biology, nucleoid can be described as a region inside the prokaryotic cell in which the DNA is present.

The prokaryotes do not have a membrane-bound nucleus like the eukaryotes. Hence, the region where the genetic material of the prokaryotes is present is an irregular shaper structure referred to as the nucleoid.

When DNA is stained with a DNA-binding dye, the suborganellar structure that will become visible will be the nucleoid as it is the region where the DNA is present.

Cells in your hair follicles produce the protein keratin, but cells in your liver do not produce keratin. Which statement explai

Art [367]

Answer:

B). Genes are expressed differently in liver cells and hair follicles

Explanation:

In given organisms all the cells of the body have the same number of genes, however, their activity varies due to <em>differential expression of genes.</em>

The differential expression of genes is regulated by several factors, such as histone modifications, DNA, etc. which may silence or activate the genes differentially in different cells.

Since the hair cells and liver cells of the organisms will have the same genes, they only vary due to the differential expression fo the genes.
