Which line of defense includes active immunity?
O first
O second
O third
O fourth
Answer:
The second line of defense.
Explanation:
In our bodies the second line of defense includes active immunity. It contains non-specific immune responses, but yet still contains specific responses for certain things such as inflammatory and fevers.
Third line of defense includes active immunity. The correct option is C.
What are lines of defense?The first line of defense consists of chemical and physical barriers that are constantly ready to defend the body against infection.
Your skin, tears, sputum, cilia, stomach acid, urine flow, 'friendly' bacteria, and white blood cells called neutrophils are examples of these.
The second line of defense assists administration in effectively managing risk and controls.
Organization develops multiple risk management and compliance functions to assist in the development and/or monitoring of first-line controls.
Immune cells that specifically target antigens are the third line of defense. B-cells and T-cells, all white blood cells, are immune cells that play a role in the third defense line.
Antibodies are produced by B-cells. T-cells aid in the identification of pathogenic cells and the destruction of those cells.
Thus, the correct option is C.

Genetics Problem Solving Chapter 25
Answer:
See the answer below
Explanation:
1. Tt x Tt
TT Tt Tt tt
Assuming that T is dominant over t:
Genotype ratio = 1TT:2Tt:1tt
Phenotype ratio = 3:1
2. Rr x Rr
RR Rr Rr rr
Assuming that R is dominant over r:
Genotype ratio = 1RR:2Rr:1rr
Phenotype ratio = 3:1
3. Assuming that green (G) is dominant over the other color (g). Heterozygous green would be Gg
Gg x Gg
GG Gg Gg gg
Genotype ratio = 1GG:2Gg:1gg
Phenotype ratio = 3:1 (green ratio the other color)
4. Assuming that green (G) is dominant over the other color (g) as above:
homzygous green plant = GG; heterozygous green plant - Gg
GG x Gg
GG Gg GG Gg
Genotype ratio = 1GG:1Gg
Phenotype ratio = 100% green
5. Assuming that tall (T) is dominant over short (t)
Homzygous tall plant = TT
short plant = tt
TT x tt
Tt Tt Tt Tt
Genotype ratio = 100% Tt
Phenotype ratio = 100% tall
Tell me one thing you know that makes prokaryotic DNA different than eukaryotic DNA.
Answer:
Prokaryotic DNA can be found in the cytoplasm whereas eukaryotic DNA is found in the nucleus, enclosed by the nuclear membrane. Prokaryotic DNA is organized into a single circular chromosome and eukaryotic DNA is organized into several linear chromosomes. The amount of eukaryotic DNA is higher than prokaryotic DNA.

October 1, 2017 marks 27 years since the beginning of the Human Genome
Project. The goal of the group was to map the entire 3 billions bases and
80,000 genes in the human genome. On April 14, 2003, it was announced
that the goal was accomplished. Using this information, scientists have been
able to predict the risk of genetic diseases and understand the process of
inheritance. Which of the following statements best describes the process of
using the genetic code to produce polypeptides (proteins)?
Translation is used to produce a strand of RNA and proteins from a single strand of DNA.
O RNA produces a strand of DNA through transcription, then the DNA builds a protein molecule
through translation
O A single strand of DNA is used to make mRNA using translation, then the mRNA provides the
template for producing a protein through transcription
O A single strand of DNA is used to produce mRNA through transcription, then translation provides
the code for bonding amino acids to make a protein.
Answer:
The last one. A single strand of DNA is used to produce mRNA through transcription, then translation provides the code for bonding amino acids to make a protein.
Explanation:
Educated guess, but also. Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins.

Copper sulfide is found written as both CuS and Cu2S. Why are there two forms for writing this chemical formula?
SELECT AN ANSWER
This is an example of a combination reaction: CuS is the halfway stage, before the second copped atom joins the molecule.
Copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+).
This is a synthesis reaction and so the formula will continue changing until all the atoms have conglomerated.
One of the versions is a mistake, the correct form should be Cu2S.
Answer:
option 3
Explanation:
Copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+).
There are two forms for writing the chemical formula because copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+)
Copper is a transition metal with variable oxidation states. The oxidation states of copper is what determines the name of CuS and Cu₂S.
Now, we shall determine the oxidation states of copper in each compound.
For CuS:
CuS = 0
S = –2
Cu =?Cu + S = 0
Cu + (–2) = 0
Cu – 2 = 0
Collect like terms
Cu = 0 + 2
Cu = +2For Cu₂S:
Cu₂S = 0
S = –2
Cu =?2Cu + S = 0
2Cu + (–2) = 0
2Cu – 2 = 0
Collect like terms
2Cu = 0 + 2
Divide both side by 2
Cu = 2/2
Cu = +1From the calculations made above, we can see that copper has oxidation state of +2 in CuS and +1 in Cu₂S
Thus, we can conclude that Copper is a transition metal with two possible ionic states and this accounts for the different names of CuS and Cu₂S

The cell cycle has a regular system of checks and balances that prevents damaged or mutated cells from proceeding to the next phase. One way an organism deals with the problems is to kill the damaged cell before it passes on the problem to its daughter cells. This is a normal process called apoptosis.
a. True
b. Fale
Answer:
A. True
Explanation:
Apoptosis is a normal cellular process in which the cell inherently programs the death of a mutated or damaged cell without affecting the healthy condition of the other surrounding cells by proliferating.
Apoptosis is a system of checks and balances that the cell uses to prevent damaged or mutated cells from proceeding to the next phase in the cell cycle. This curbs or prevent the damaged cell from passing on the problem to its daughter cells. Hence, according to this question, it is TRUE.

What happens during Prophase I? You will need to think about what you learned during mitosis to fully answer the question.
DNA coils into chromosomes
Crossing over
Nuclear Membrane disappears
Chromosomes line up in the middle of the cell
Answer:
Crossing over
Explanation:
Prophase I is the first stage of meiosis I, it is the longest phase of meiosis. Crossing over (also known as recombination) can be defined as the process of exchange of genetic material between non-sister chromatids that occurs during Prophase I. Crossing over represents a critical source of genetic variation in offspring (the other one is the random orientation of the homologous chromosomes pairs). After crossing over, the resulting haploid (n) gametes aren't genetically identical to one another.

Explain the basis for the great diversity of proteins in living organism.
Answer:
Explanation:
Protein functions are so diverse because of the many unique three-dimensional structures protein polymers form. Despite such variety, proteins also share several specific structural characteristics in their monomers, the amino acids. Structural similarities among amino acids make protein synthesis a uniform and regulated process; however, each amino acid contains a unique structural component as well. Specific differences between each amino acid interact to create unique three-dimensional protein structures. Combined, the similarities and differences between amino acids explain how cells can build a diverse pool of proteins from the same set of building blocks. Protein synthesis involves building a polymer of amino acids with complex three-dimensional structure. Dehydration synthesis forms a peptide bond between amino acids and releases a water molecule.

The creation of new crust at the middle of mid-ocean ridges is also
referred to as... *
A.mountain formation
B.sea floor spreading
C.fault formation
D.a transform boundary
Answer:
B.sea floor spreading
Explanation:
The creation of new crusts at the middle of the mid- ocean ridges is also sea floor spreading.
The process of sea floor spreading entails the creation of new crusts at the margin of the oceanic crusts.
Basaltic materials from the subsurface upwells to the surface.
They cool and solidifies to form new crusts. The old crust is moved behind and away from the margin. This way, sea floor is formed and it spreads in like manner.
At this margin sea floor is created and at a convergent margin, it is destroyed.
