Explain the 3 graphs about the pattern of natural selection on polygenic traits.
Answers
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?
Answers
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.

The picture below shows a satellite image of the oceans on Earth. Picture shows a color-coded map showing the height of the world's ocean surfaces at a particular time. Purple areas correspond to approximately 10 centimeters below normal. Light blue areas correspond to approximately 2 centimeters below normal. Green areas correspond to approximately 3 centimeters above normal. Red areas correspond to approximately 10 centimeters above normal. In this map, area A is colored red and area B is colored purple. Which of these statements is correct about the ocean at Location A and Location B? The waves at Location A have low frequency. The waves at Location B have low frequency. The waves at Location B are abnormally high. The waves at Location A are abnormally high.
Answers
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.

Describe the relationship between ATP and ADP?
Answers
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.

Carbon dioxide is a reactant of cellular respiration, and water is a product of photosynthesis.
Carbon dioxide is a product of photosynthesis, and water is a reactant in cellular respiration.
Answers
Answer:
the answer is C
Explanation:
The type of the respiration that are taking place inside the cells are called as the cellular respiration in which carbon dioxide is the reactant and the water along with it is the bi product. The correct answer is option C.
What are the two products in the process of photosynthesis ?
The products of photosynthesis are oxygen that is released out with the glucose that is the sugar molecule which is the stored form of energy.
Photosynthesis converts out carbon dioxide and the water into the oxygen and typically glucose. Glucose is then used as the food by plant and the oxygen that is a by-product of the process. Cellular respiration later just converts out oxygen with the glucose into the water and carbon dioxide.
Water and the carbon dioxide are just the by- products along with the ATP that is the energy which is just transformed out from process. In the process of the cellular respiration where the glucose and oxygen together just reacts in order to form the ATP. Water and the carbon dioxide are just released as the byproducts.

Identify a human disorder with developmental limitations that results from changes in chromosome number. Explain how nondisjunction leads to changes in chromosome number.
Answers
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.
