1. What is a scientific investigation?
Answer:
A scientific investigation is a plan for asking questions and testing possible answers. A scientific investigation typically begins with observations. Observations often lead to questions. A hypothesis is a possible logical answer to a scientific question, based on scientific knowledge.

The second generation of a purebred cross of a h.o.m.o.zygous recessive organism, with a h.o.m.o.zygous dominant organism, contains a ratio of approximately ____ expressed dominant traits to recessive traits.
a. 1:1
b. 1:3
c. 2:1
d. 3:1
Answer:
d. 3:1
Explanation:
A purebred organism is an organism that contains identical alleles for a particular gene e.g rr or RR. According to this question, in a cross between a purebred dominant organism e.g RR and a purebred recessive organism e.g rr, each parent will produce R and r gametes respectively.
Using the gametes in a punnet square (see attached image), a heterozygous organism (Rr) will be produced in the F1 generation. If these heterozygous organism is self-crossed i.e. Rr × Rr, the following F2 offsprings will result;
RR, Rr, Rr, and rr.
RR, Rr and Rr will exhibit dominant traits while rr will exhibit recessive traits. This means that the F2 generation contains a ratio of approximately 3:1 expressed dominant traits to recessive traits.

Define biodiversity and describe how biodiversity (the variety of life in a particular habitat or ecosystem) helps keep an ecosystem healthy.
Answer:
Biodiversity is a variation of organisms (plants, animals and bacteria) in the world or a specific habitat. Biodiversity helps to keep an ecosystem healthy because there is more variation of food and different organisms can rely on each other for survival. Also it offers a larger more reliable food chain and if one species is suddenly wiped out, it won't impact the ecosystem as much as it would if the biodiversity was smaller.

The process of transcription is known to have a less effective “proofing” stage to check the sequence of bases than does the process of DNA replication. What effect does this have on the base sequences produced by transcription?
A.Errors in the base sequences will result in a damaged strand of DNA.
B.The base sequences of mRNA can be exactly the same as those on DNA.
C. It is more likely that there will be more errors in coding base sequences in mRNA than there will be in DNA.
D. It is more likely that there will be fewer errors in coding base sequences in mRNA than there will be in DNA.
What does relative humidity measure?
Relative humidity (RH) (expressed as a percent) also measures water vapor, but RELATIVE to the temperature of the air. In other words, it is a measure of the actual amount of water vapor in the air compared to the total amount of vapor that can exist in the air at its current temperature.
In comparison to the greatest amount of moisture that might be present at that temperature, relative humidity measures how much moisture is really in the air.
The amount of moisture in the air as compared to the maximum amount that might exist at given temperature is measured as relative humidity. It shows how saturated the air is with water vapour and is given as a percentage. A greater relative humidity signifies that the air is drier and is more likely to be approaching its maximum moisture-holding capacity than a lower relative humidity.

NS is a 32-year-old female who had been sick with a cold virus for 10 days. She states that she had flu symptoms of cough, sore throat, and fatigue. It has been 3 weeks since the cold, and she continues to be fatigued and finds it hard to get enough energy to do things. NS says she has noted that she has been bruising easily. She hit her arm accidentally on the edge of a counter, and now she has a large bruise. She has also noted little purple spots all over her hands and chest. On exam it is noted that she does have a large bruise on her right arm and petechiae and purpura over her chest and hands. Lab work comes back with a platelet count of 40,000mm^3.
Required:
NS has been diagnosed with idiopathic thrombocytopenic purpura (ITP). Explain what it is and who can get it.
Answer:
Idiopathic thrombocytopenic purpura or ITP is also known as Immune thrombocytopenic purpura that is a disorder in which there is an abnormality in the clotting of blood due to a decreasing number of platelets in an individual.
Platelets plays role in clotting the blood to prevent bleeding so this disorder leads to easy bruising, bleeding gums, and internal bleeding. It is an autoimmune disorder as in this case, an immune reaction takes place against one's own platelets.
It occurs in all age and sex groups however, it occurs normally in young children and females more often.

Why does the body use an RNA to leave the nucleus and give the message of the DNA to the ribosome?
ribosomes which make proteins are not found inside the nucleus but on endoplasmic reticulum and in cytoplasm. DNA creates RNA to do this job of leaving nucleus and delivering genes so that proteins are created.

where does an organism inherit its genetic instructions from
Answer:
Organism's parent.
Explanation:
Trait can be defined as the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.
Simply stated, a trait refers to the distinguishing characteristic or quality of any living organism.
Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.
For example, John is so tall and has a curly hair, it's obvious he acquired the trait from his mum.
In Genetics, a trait comprises of all the genetic instructions that are typically being transfered from the parent to their offsprings.
Hence, an organism inherit its genetic instructions from its parent.
