You have learned that each one of your cells contains one copy of your unique genome. Given the fact that all the cells in one human contain the same DNA, how is it possible that our cell types are so different, resulting in four different tissue types?
Answer:
See the answer below
Explanation:
Yes, the cells in one human contain the same DNA. However, during gene expression, not all the genes are expressed for every cell. Only a specific region of the DNA is expressed in cells and the cells in which the same DNA region is expressed end up performing similar roles in the body of organisms. The portion of the DNA that is expressed dictates the function which these cells will serve. This is called the differentiation of cells.
Cell specialization and tissue differentiation are due to the fact that although somatic cells have the same DNA, they express different genes and therefore generate different cells/tissues.
The human body contains approximately 200 cell types, which can be classified into four types of tissues: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
All these tissues and cell types are derived from three embryo layers, i.e., ectoderm, mesoderm, and endoderm.
The process of differential gene expression from these three embryo layers leads to the development of different types of cells/tissues in different regions of the developing embryo.
For example, the expression of the connective tissue growth factor (CTGF) gene has been associated with the generation of connective tissue during embryo development.
In conclusion, cell specialization and tissue differentiation are due to the fact that although somatic cells have the same DNA, they express different genes and therefore generate different cells/tissues.

Explanation:
What do ribosomes produce following
instructions from the nucleus?
A. energy
B. proteins
C. DNA
Answer: Here's what I could find:
Ribosomes get their orders for protein synthesis from the nucleus, where portions of DNA (genes) are transcribed to make messenger RNAs. An mRNA travels to the ribosome and uses information it contains to build a proteins with specific amino acid sequences.
Explanation: I'm pretty sure it's protein, if not then it's DNA.

Explain how the nucleus works with the ribosome to create proteins for the cell.
They receive their order for protein synthesis from the nucleus where the DNA is transcribed into messenger RNA, which is also called (mRNA). mRNA travels to the ribosomes, which translate the code provided by the sequence of the nitrogenous bases in the mRNA into a specific order of amino acids in a protein.
A nurse made a tragic mistake and hooked a sick patient up to an IV line that included pure water. The contents of the IV bag were then injected into the patient. The patient is now getting sicker. What could be happening?
Answer:
The water is hypotonic to the body of the patients
Explanation:
Pure water is generally hypotonic to the red blood cells in the body of humans. Hence, if a person is hooked up to an IV line that included pure water, the red blood cells in the person's body will take-in water, become turgid, and then start lysing. This will make the person become sick or even cause death in severe cases.

What trend in the complexity of life over time is seen through the fossil record?
Most animal and plant species we see in the fossil record are extinct, or no longer living. In fact, of all the species that ever lived, 98% are extinct. Animals and plants become extinct over time as a result of natural processes. Their habitat might change or a disease might wipe out a species.
The trend of extinction and difference in body parts in the complexity of life
over time is seen through the fossil record
Fossils refers to remains of living organisms which have been replaced in the form of rock particles due to its presence in the soil for a long period of time.
The fossils contain an understanding of the structures and characteristics
the animals had which is then compared to its present structures. This helps
to explain how the animals adapted to climate change through changes in
the structure, shape of parts of the body.
It also tells the location of animals and their different movements in response to challenges faced in the ecosystem.

C.
iron powder dusting
D.
silver nitrate exposure
E.
superglue fuming
The technique that would most probably involve using a Magna brush to detect a latent print is known as Iron powder dusting. Thus, the correct option for this question is C.
What is Latent print?Latent print may be defined as an impression of the friction skin of the fingers or palms of the hands that have been transferred to another surface. The permanent and unique arrangement of the features of this skin allows for the identification of an individual as a latent print.
Iron powder is commonly placed into brake pads, drum brake lining, and other applications in order to construct the necessary amount of friction. Iron powder dusting is a type of technique that is utilized as a filler that can help increase the performance and durability of these products by dissipating the generated heat.
Therefore, iron powder dusting is a type of technique that would most probably involve using a Magna brush to detect a latent print. Thus, the correct option for this question is C.
