Explanation:
What would you expect to happen if your blood sugar was 120mg/100mg?
Answer:
The 120 miligram per 100 milliliter of the sugar suggests that the blood is hyperglycemic.
Explanation:
the hyperglycemia is the condition, in which the blood sugar level increases than the normal blood sugar levels. The main cause of the insulin is decreased function of the insulin hormone. The condition, in which the insulin is not working properly and is unable to metabolise the sugar (glucose) present in the blood is known as Diabetes.
So, the given case can be a result of diabetes.

Explain the 3 graphs about the pattern of natural selection on polygenic traits.
Answer:
Directional selection, stabilizing selection and disruptive selection are three types of natural selection
Directional selection
In population genetics, directional selection, or positive selection is a mode of natural selection in which an extreme phenotype is favored over other phenotypes, causing the allele frequency to shift over time in the direction of that phenotype
stabilizing selection
Stabilizing selection is a type of natural selection in which the population mean stabilizes on a particular non-extreme trait value. This is thought to be the most common mechanism of action for natural selection because most traits do not appear to change drastically over time
disruptive selection
Disruptive selection, also called diversifying selection, describes changes in population genetics in which extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups.

James is working with the lac operon of Escherichia coli (E. Coli). He places the bacteria on a plate of growth media. The lac Operon of E. Coli is shown. Based on the current understanding of this operon, which hypothesis would be useful for James to test?
Answer:
A.
Explanation:
Lac Operon is defined as an operon that is used by E.coli for transporting and metabolizing lactose.
Allolactose is a disaccharide like lactose, that binds to lac repressor and restrict its binding with DNA. It triggers expression of a operon or gene.
So, adding allolactose to the bacterial growth media, block the activity of lac repressor and trigger the activity of bacteria to metabolize the sugar lactose.
Hence, the correct answer is "A."
Based on the current understanding of this operon hypothesis would be useful for James to test addition of all lactose to the bacterial growth media should increase the speed at which the bacteria metabolize the sugar lactose. Thus, option A is correct.
What is the mode of reproduction of bacteria?The bacteria reproduces through the process of asexual reproduction and the amoeba reproduces through the process of binary fission. Reproduction is defined as the process carried out by the living organisms and during the process of reproduction the living organisms produces their own young ones and feed them. Reproduction is the supreme quality of living things.
There are two types of reproduction and these are sexual and asexual reproduction. The process of reproduction in which two parents are involved is said to be sexual mode of reproduction and the process of reproduction in which only single parent is involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.
Therefore, Based on the current understanding of this operon hypothesis would be useful for James to test addition of all lactose to the bacterial growth media should increase the speed at which the bacteria metabolize the sugar lactose. Thus, option A is correct.

Describe the relationship between ATP and ADP?
Answer:
If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell. ... When it's run down, it's ADP.
Answer:
Think of it as the “energy currency” of the cell. If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. ... When it's fully charged, it's ATP. When it's run down, it's ADP.

discuss the stages of the cell cycle mechanism that regulate it and how this cycle is related to the growth and maintenance of organisms
Answer:
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
Cyclins regulate the cell cycle only when they are tightly bound to Cdks. To be fully active, the Cdk/cyclin complex must also be phosphorylated in specific locations. Like all kinases, Cdks are enzymes (kinases) that phosphorylate other proteins. Phosphorylation activates the protein by changing its shape.

The waves at Location B are abnormally high. The waves at Location A are abnormally high.
Answer:
I'm gonna go with the fourth one
The waves at Location A are 10 centimeters above normal, which is considered abnormally high.
The image shows a color-coded map of the ocean, with red areas indicating that the ocean is 10 centimeters above normal, purple areas indicating that the ocean is 10 centimeters below normal, and so on. Location A is colored red, which means that the ocean at that location is 10 centimeters above normal. This is considered abnormally high, as the normal range for ocean height is 2-3 centimeters above or below normal.
Location B is colored purple, which means that the ocean at that location is 10 centimeters below normal. This is not considered abnormally high, as it is within the normal range for ocean height.
Therefore, the only statement that is correct about the ocean at Location A and Location B is that the waves at Location A are abnormally high.

What is something from our unit on heredity that you think you will remember one year from now?
Identify a human disorder with developmental limitations that results from changes in chromosome number. Explain how nondisjunction leads to changes in chromosome number.
Answer:
The Klinefelter syndrome is caused by the presence of one extra X chromosome (i.e., XXY males). Developmental limitations of this genetic disorder include: reduced muscle mass, neurodevelopmental problems, hypogonadism, etc. Abnormal chromosome numbers (known as aneuploidies) are usually caused by the nondisjunction of homologous chromosomes during Anaphase I or the nondisjunction of sister chromatids during Anaphase II
Explanation:
The Klinefelter syndrome is the most common sex chromosomal disorder in males, which is caused by the presence of an extra X chromosome (i.e., males with a XXY karyotype). This genetic disorder has many effects on development, including small testes (hypogonadism), weaker muscles, longer arms and legs, larger breasts than normal, infertility, immature development of secondary male sex features, cognitive problems (e.g., speech and language delays), etc. A chromosomal disorder occurs when chromosome pairs or chromatids fail to separate during meiosis, thereby producing cells (gametes) with more or fewer chromosomes than normal, a phenomenon known as aneuploidy.

Natural selection causes what to occur?
Answer:
Natural selection causes populations to become adapted, or increasingly well-suited, to their environments over time. Natural selection depends on the environment and requires existing heritable variation in a group.
Hope this helped!! Have a great day!! :))
Explanation:
Answer:
(I'm not sure if this is what you mean) It causes reproduction, heredity, variation in physical characteristics and variation in number of offspring per individual to occur.
Explanation:
If the four conditions (reproduction, heredity, variation in physical characteristics and variation in number of offspring per individual) change, then a natural selection occurs.
