<span>Out of the following given choices;</span>
a. they are used up in the reactions
b. they lower the overall energy of the reactions
c. they lower the activation energy of the reactions
d. they keep the temperature of the reactions constant
<span>The
answer is C. A catalyst provides an different route for a reaction, mostly
bypassing some transitional states hence lowering the reaction energy. The
catalyst is not consumed in the reaction. </span>
Answer:
<em>True: </em><u>b) Tissue is a group of specialized cells that work together for a common function and form organs.</u>
Explanation:
Cells are the smallest units of life, they may be either unicellular or multicellular. Unicellular organs have a single cell capable of carrying out all of the functions necessary for its survival. Multicellular organisms are more complex, and require the work of multiple different cell types.
Their cells become differentiated- where they undergo certain processes to become specialized, and gain maturity. Groups of specialized cell types form tissue; these each have varying functions over time. Organs consist of two or more tissue types that are specifically organized to carry out a function.
Answer:
it is examining the lipid level of the cells
Explanation:
The general procedure includes: 1) the isolation of the DNA from an evidence sample containing DNA of unknown origin, and generally at a later time, the isolation of DNA from a sample (e.g., blood) from a known individual; 2) the processing of the DNA so that test results may be obtained; 3) the determination of the ...
