Why do cells become specialized in the human body?
Answer:
They can become any type of cell in the body.
Explanation:
They can transport molecules, metabolize nutrients, and reproduce within this one cell. ... Cell differentiation is the process by which cells become specialized in order to perform different functions. Specialized Cells in the Human Body.

thinking about the components in pcr, do you think there are major differences in the process of dna replication between species?
The major difference in the process of DNA replication between species is the linear order of nucleotides, which can be amplified by PCR. This technique enables the amplification of specific DNA fragments.
The Polymerase chain reaction (PCR) is a technique widely used in molecular biology in order to amplify and thus identify small DNA fragments (approx. 1000 pb).
The PCR uses all materials required to carry out DNA replication: a thermostable DNA polymerase, primers (DNA oligonucleotides), deoxyribonucleotides (ddA, ddG, ddC, or ddT), and template DNA.
The template DNA indicates the linear order of nucleotides that will be added to the amplified DNA fragment, which is highly specific and may vary even between individuals of the same species.

Answer:
In case of multiple alleles, the same DNA strand is involved, whereas polygenic inheritance is found on multiple DNA strands. Multiple alleles involve multiple alternate forms of a gene, while polygenic traits are regulated by a group of non-allelic genes. ... Hence, in blood type, there is one gene but three alleles

how does the sequence of amino acids relates to the functioning of a protein.
Answer:
The function of a protein is determined by its shape. The shape of a protein is determined by its amino acid sequence. (Primary, Tertiary, Secondary, Quaternary)
Explanation:
There are 22 amino acids used within the human body. How can these 22 molecules be used to make hundreds of thousands of different proteins?
Answer:
Because amino acids can be arranged in many different combinations, it's possible for your body to make thousands of different kinds of proteins from just the same 21 amino acids. You may see books that say there are only 20 amino acids.
In the diagram of the human digestive system, what organ is labelled 5?
Answer:
The large intestine
Explanation:
The large intestine is a long, tube-like organ connected to both the small intestine and the anus. In an anatomy drawing, it looks almost as if it is wrapped around the small intestine.
As we can see in the drawing, the organ labelled with 5 is wrapped around another organ which is smaller and looks longer. This smaller organ is the small intestine. Since we know that the large intestine wraps around the small intestine, we can infer that the organ is the large intestine.

4 Spheres Observation (Bio, Geo, Atmo, Hydro) : What did you see that represents each? How did they interact with each other? and pls be specific in ur answer, and pls no links!
Answer:
The spheres interact to effect Earth’s systems and processes, and they are constantly changing each other.
For example, ocean currents (hydrosphere) affect air temperature (atmosphere): The Gulf Stream is a powerful water current in the Atlantic Ocean. It’s warm water moderates the temperatures on the east coast of the USA.
Another example of how the spheres affect each other is through erosion. Erosion happens in the desert when wind (atmosphere) shapes the sand in the geosphere. Water (hydrosphere) can also shape land, such as in the formation of the Grand Canyon.
Humans have a huge impact on all spheres. Negative impacts, such as burning fossil fuels, pollute the atmosphere. Piling up our waste in landfills affects the geosphere. Pumping waste into the oceans harms the hydrosphere. And overfishing and habitat destruction can reduce the diversity of living things in the biosphere.
However, people everywhere are working to change things. Recycling efforts are increasing all over the world, and companies are finding new ways to reduce fossil fuels. In the US alone, people are recycling six times more than a generation ago.

Hello!!
What tissues make up a leaf?
Leaves include two different types of photosynthetic parenchyma cells (palisade and spongy). Like all plant organs, they also contain vascular tissue (not shown). Monocots tend to have parallel veins of vascular tissue in leaves, while dicots tend to have branched or net-like veins of vascular tissue in the leaves.
