The color distribution for a specific population of snakes is 160 blue, 50 turquoise, and 40 green. The allele for the color blue is represented by BB, whereas the allele for the color green is represented by BG. Both alleles demonstrate incomplete dominance
Genotype frequency is calculated as the ratio of the number of people with that genotype to all people. Blue gecko genotype frequency (BBBB) is 160/(160 + 50 + 40) = 160/250 = 0.64. Turquoise gecko genotype frequency (BBBG) = 50/250 = 0.20 Green gecko genotype frequency (BGBG) = 40/250 = 0.16
When both alleles of a gene are only partially expressed at a locus, it is known as incomplete dominance. This sort of gene interaction frequently produces an intermediate or distinct phenotype. It's sometimes referred to as "partial domination."

Draw the structure of a simple autonomous DNA transposon and answer the following:
A. What is the origin of each component during cut-and-paste transposition?
B. What is the function of each component during cut-and-paste transposition?
The origin of each component during cut-and-paste transposition is transposon and transposase enzyme. the function of each component during cut-and-paste transposition is to move gene from one location to another within the genome and to catalyzes the reactions that lead to the movement of the transposon.
The transposon is the genetic element that is moved from one location to another within the genome. The transposase enzyme is the enzyme that catalyzes the reactions that lead to the movement of the transposon. It binds to the transposon and recognizes the specific sequences that mark the boundaries of the element, and then catalyzes the reactions that lead to the excision and integration of the transposon into a new location in the genome.

Explain what happens to the percentage stomatal opening when plant roots are partially exposed to
water compared to when they are fully exposed to water. Justify your answer using the graph above.
Through their stomata, plants transpire their water in the form of vapor or gas. Stomatal transpiration, or between 50 and 90 percent of all transpiration, loses the most water.
How do stomata respond to water status?
We still don't have a complete mechanistic knowledge of how stomatal responses to humidity, soil moisture, and other factors that affect plant water status affect photosynthesis, productivity, water production, ecohydrology, and climate forcing. Here, I go over earlier and more current developments in stomatal water interactions. The synthesis of abscisic acid in leaves may play a role in the metabolically mediated response to leaf water status in stomatal responses to evaporative demand and soil drought. Humidity, light, and temperature responses may also be influenced by additional speculative mechanisms involving vapor and heat transfer within leaves, although these mechanisms need more theoretical development and experimental verification..

A. cell division
OB. nuclear division

O D. cell respiration
Answer:
A. Cell division
Explanation:
What is mitosis? Mitosis is a type of "cell division" in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself.
Some proteins are destined to stay in the cell, while others are to leave the cell (secretion).
Are these two types of proteins produced in loose ribosomes? Explain.
Both types of protein can be produced by ribosomes, however, proteins that are destined to be secreted are often produced by ribosomes that are attached to the endoplasmic reticulum.
How do cells determine which proteins are destined to stay within the cell and which are to be secreted?Cells determine which proteins are destined to stay within the cell and which are to be secreted through the use of a process called protein sorting. This process occurs during protein synthesis and involves the addition of specific signals or tags to the protein, such as a signal peptide or a transmembrane domain. These signals act as a sort of "address label" that directs the protein to its proper destination within the cell or out of the cell through the secretory pathway. Proteins that are not tagged for secretion will typically remain within the cell and may serve a variety of functions such as enzymes, structural proteins, or regulatory proteins.

Who observed the variation of organism in Gala?
Charles Darwin observed the variation of organisms in the Galápagos Islands during his voyage on the HMS Beagle in 1835.
Charles Darwin's observations of the variation of organisms in the Galápagos Islands, greatly influenced his theory of evolution by natural selection. While exploring the various islands in the Galapagos, Darwin noticed that the animals and plants on each island had slight differences from the same species on other islands.
This led him to conclude that the differences were caused by the different environments on each island, and that this could lead to the evolution of new species over time. This observation was a major factor in the development of Darwin's theory of evolution by natural selection, which has since become one of the most widely accepted theories in the field of biology.

Temperature is an influencing factor on enzymatic activity. The exposed graph ilustrates the optimum enzymatic activity. B) El gráfico se podría utilizar lo mejor posible para ilustrar una actividad enzimática optima.
How does temperature influence enzymatic activity?Enzymes are proteins, so they share many properties with all proteins. One of these properties is that they have a limited temperature level at which they denaturalize.
In general,
The increase in temperature accelerates chemical reactions. For every 10ºC of temperature increase, the reaction velocity duplicates. The temperature at which the enzymatic activity is the highest is known as the optimum temperature. After this point, the enzymatic activity sharply decreases. The environmental temperature exceeds the optimum one and denaturalizes the enzyme.Over this level, the reaction velocity is counteracted by the loss of the catalytic activity due to denaturalization. Enzymatic activity decreases until it completely annulates.
The exposed graph shows
an increase in the enzymatic action as temperature increases from from 0ºC to 40ºC. At thi point, the enzyme expresses its maximum rate of reaction. 40ºC is the optimum temperature at which the enzymatic activity is the highest. From 40ºC to 60ºC there is a sharp decrease in enzyme activity due to denaturalization.So this graph can be used to ilustrate the optimum enzymatic activity.
