Ion pumps and phagocytosis are both examples of active transport. Therefore, the correct option is C.
The movement of molecules or ions across the cell membrane against a gradient of concentration, from an area of lower concentration to an area of higher concentration, is called active transport. In this whole process energy must be used in the form of ATP (adenosine triphosphate).
Ion pumps are membrane proteins that actively transport ions across the concentration gradient across the cell membrane. These ions include sodium, potassium, calcium or hydrogen ions. The ion concentration imbalance required for many cellular functions is maintained by these pumps.
On the other hand, phagocytosis is a type of endocytosis in which cells engulf large molecules or solid particles and internalize them. Energy is required for the formation of pseudopods and for the solubilization of substances in the phagosome inside the cell.
Therefore, the correct option is C.

Which factor contributed most to the development of the cell theory?
The factor that contributed most to the development of the cell theory is the advancement in technology.
With advancements in the area of technology, significant improvements were made to the primitive microscope initially invented by the likes of Hans and Zacharias Janssen, and more powerful microscopes like the electron microscopes were invented. With these, details of the cell could be observed and all the organelles could be studied, including how the cell divides (give rise to another cell).
Still on the technological advancement, the discovery of differential staining materials made it possible to differentiate several biological phenomena as they relate to the cell.
Thus, by extensively studying the cell using microscopes and differential staining dyes, the cell theory was developed by the likes of Theodore Schwann, Mathias Schleiden and Rudolf Virchow.

Enzymes are important proteins in your cells that speed up important biochemical reactions such as building muscle or breaking down large food molecules.
How are enzymes important for biochemical reactions?Enzymes are often called a catalyst because they increase can the speed of a biochemical reaction. Scientists often measure how quickly biochemical reactions occur in cells. The time it takes for a biochemical reaction to start and finish is known as the reaction rate.
Enzymes share two key characteristics with all other catalysts. First, they speed up chemical processes without being eaten or irreversibly changed by the process. They also speed up reactions while maintaining the chemical equilibrium between reactants and products.
Therefore, the enzyme acts as a catalyst to speed up a biochemical reaction.

Fruit flies (Drosophila melanogaster) with a wild-type phenotype have gray bodies and red eyes. Certain mutations can cause changes to these traits. Mutant flies may have a black body and/or cinnabar eyes. To study the genetics of these traits, a researcher crossed a truebreeding wild-typed male fly with a true-breeding female fly with a black body and cinnabar eyes. All of the F1 progeny displayed a wild type phenotype. Which of the following is correct about the traits observed?a. Gray body and cinnabar eyes are dominant.b. Eye color is sex-linked.c. Body color is sex-linked.d. Gray body and red eyes are dominant.
Answer:
d
Explanation:
The correct answer would be that gray body and red eyes are dominant.
The wild type trait is represented by gray bodies and red eyes while the mutant trait is represented by black body and/or cinnabar eyes. A cross between the wild type and the mutant only yield F1 offspring with wild type phenotype. This, thus, means that the wild type trait is dominant while the mutant trait is recessive.
Since the wild type trait is depicted by gray body and red eyes, it means that the gray body and red eyes traits are dominant while the black body and cinnabar eyes are recessive.
The correct option is d.

3. There are multiple types of mutations in DNA.
mutations occur when a single base is
changed to a different base pair.
mutations remove one or more bases from a segment of DNA,
resulting in a frameshift mutation.
mutations are also considered frameshift mutations, and occur when
one or more extra bases are added to a segment of DNA.
Check Answer
Answer:
substitution, deletion, insertion (in that order)
Explanation:
I did the assignment-
Mutations occur when a single base is changed to a different base pair; mutations remove one or more bases from a segment of DNA, resulting in a frameshift mutation, so this is also correct in other statements.
What is the significance of the DNA mutation?Mutations in DNA lie in their ability to alter the genetic information, and that altered information is passed on to next generations while Some mutations have no effect on the function of the proteins, but some have serious effects. It helps in the evolution process by providing a mechanism for the development of new traits, etc., in nature, so it has a significant role in it.
Hence, mutations occur when a single base is changed to a different base pair; mutations remove one or more bases from a segment of DNA, resulting in a frameshift mutation, so this is also correct in other statements.

Using the concepts of chain of custody it is important to (multiple answer) A. document everyone who has handled the evidence prior to a trial B. record the dates and times of the possession of the evidence C. have a complete inventory of the evidence D. weight all of the evidence E. seal all of the evidence in air tight bags
Answer:
A. document everyone who has handled the evidence prior to a trial
Explanation:
A chain of custody can be defined as a paper trail containing the chronological order of items of evidence and how they have been handled, controlled, transferred, analyzed, and disposed during the investigation of a case.
This ultimately implies that, a chain of custody contains all the details or informations regarding the investigators (people) who handled, controlled, transferred, analyzed, and disposed an evidence in the course of carrying out investigations on a particular case. The most important and significant part of an investigation is the evidence because it helps to unravel the truth and facts relating to a case. Therefore, it is very important and essential to document and maintain a chain of custody so as to preserve the evidence.
Hence, using the concepts of chain of custody it is important to document everyone who has handled the evidence prior to a trial.
