Explanation:
Describe the temperature, moisture and air pressure associated with a Continental Polar air mass.
Use this and the picture to help
Continental Polar Air Masses
cold temperatures and little moisture
Those who live in northern portions of the United States expect cold weather during the winter months. These conditions usually result from the invasion of cold arctic air masses that originate from the snow covered regions of northern Canada. Because of the long winter nights and strong radiational cooling found in these regions, the overlying air becomes very cold and very stable. The longer this process continues, the colder the developing air mass becomes, until changing weather patterns transport the arctic air mass southward.
Answer:
Continental polar has very low temperatures, little precipitation, and air pressure varies with the pressure system moving through
The variation in the US continental region is due to the change in the weather during the day and the night.
These are the reasons for the polar air mass:-
BreezeHigh humidityThe low temperature at the nightContinental Polar air usually forms during the cold period of the year over extensive land areas.
The upper part of the region has a cold breeze while the lower part has a warm breeze.

Can you determine the relationship between the risk of contracting Lyme disease and the concentration of ticks that act as vectors for the disease?
Answer: Since the vector transmitting the disease is the tick, the higher the density of ticks, the higher the rate of transmission of the disease.
Explanation:
Lyme disease is an infection caused by a spirochete-like bacterium of the Borrelia species and is transmitted by a vector, which is a living being (almost always an arthropod) capable of transmitting a disease to vertebrate hosts, including humans.
In this case, the disease is transmitted to humans through the bites of deer ticks that are infected with this bacterium. The ticks live in forests or grassland areas, woodlands and swamps near rivers, lakes or seas. Infections generally occur from late spring to early fall because infected deer ticks live in regions that have extreme temperatures (very low and very high) and high levels of humidity.
The first and most obvious symptom of Lyme disease is a localized rash that begins as a pink or red circle that expands over time and may appear 3 to 30 days after the bite. Although the disease can also affect the skin, nervous system, joints, muscles and heart.
Therefore, since the vector transmitting the disease is the tick (without ticks there is no transmission), the higher the density of ticks, the higher the rate of transmission of the disease.

Answer: Your answer is Sexual reproduction
Explanation:
The sperm and eggs produced with sexual reproduction provide genetic diversity because their gene combinations differ from those in the parent organisms. Asexual reproduction is called asexual reproduction because the person splits into two people that have the same genes, as opposed to sexual reproduction.

Teniendo en cuenta problemáticas de la biología o de su aprendizaje ,pensar un tema investigar desde el enfoque cualita tivo y otro desde el enfoque cuantitativo
Answer:
Caso de estudio: El efecto de estresores ambientales sobre el comportamiento animal
- Ejemplo de un tipo de estudio cualitativo: la influencia de estresores ambientales (por ej. niveles anormales de dióxido de carbono atmosférico) sobre el comportamiento en ratones de laboratorio
- Ejemplo de un tipo de estudio cuantitativo: la influencia de estresores ambientales sobre los niveles de producción de hormonas asociadas a cambios comportamentales en ratones de laboratorio
Explanation:
Un enfoque cualitativo se caracteriza por el hecho de que la información obtenida durante dicho estudio se agrupa en categorías mutuamente excluyentes. En biología, los estudios de tipo cualitativo generalmente se caen dentro de la dicotomía observacional (es decir, presencia o ausencia del factor en estudio). En el ejemplo arriba citado, es posible obtener datos relacionados a uno o más determinado aspectos comportamentales en los individuos bajo estudio (por ejemplo, presencia o ausencia de signos de irritabilidad) en ratones sometidos a algún estresor ambiental (por ejemplo, niveles anormales de CO2 atmosférico). Por otra parte, en un enfoque cuantitativo, la información se recopila en intervalos obtenidos a partir de operaciones aritméticas (estadística paramétrica). En el ejemplo, los datos obtenidos pueden ser clasificados en intervalos referidos a los niveles hormonales. Esta información resulta útil para determinar si las diferencias en los niveles hormonales entre individuos que se encuentran en presencia del estresor ambiental son estadísticamente significativas respecto al grupo control (individuos desarrollados en un ambiente con niveles normales de CO2 atmosférico), y de este modo concluir si el estresor ambiental puede o no modificar variables comportamentales. Los estudios cualitativos permiten el uso de variables independientes las cuales son clasificadas como cualitativas (discretas).

9- The results of this type of DNA analysis are often used to help
determine *
A) the number of DNA molecules in an organism
B) if two species are closely related
the number of mRNA molecules in DNA
OD) if two organisms contain carbohydrate molecules
Answer:
B) if two species are closely related.
Explanation:
DNA analysis is used to determine the relationship between two species in order to check their relations with each other because DNA molecules has all the information about the organisms. If there is more similarities between two organisms so they are more closely related to each other while on the other hand, if there is no similarities between two species so we can say that there is no relationship exists between two organisms or species. All this discussion describes the usefulness of DNA analysis.

where do you see collision in a roller coaster ride?
Answer:
i dont think that happens very often
Explanation:
Base your answer to this question on the following information: You have isolated a primary signal factor from the blood of a space alien, which you name XFF (for X-files factor). You also have Isolated various types of alien cells which appear to Interact with XFF. Based on preliminar data, you think that XFF could be similar to one of three compounds normally found in human blood: epidermal growth factor (EGF), epinephrine, or estrogen. Which of the following would best be used to demorstrate XFF is most like EGF?
A. exposure of cells to tyrosine kinase inhibitors
B. microinjection into cells of nonhydrolyzable GTP analogues
C. exposure of cells to ryanodine
D. exposure of cells to radioactive XFF
E. receptor binding assays
Answer:
The correct answer is - A. exposure of cells to tyrosine kinase inhibitors.
Explanation:
EGF or epidermal growth factor is a protein compound found in human blood responsible for signaling is the member receptor tyrosine kinase family of proteins.
EGF signaling leads to activation or stimulation of various pathways such as Phosphatidylinositol 3-kinase, Ras and or Raf signaling, and or Akt signaling chain of reactions, or STAT pathway. By exposing the cells to the tyrosine kinase inhibitors leads to any of the given pathways then XFF is most likely similar to EGF.

A married couple plans to have children. The wife has blue eyes (a recessive trait) and her husband has brown eyes (a dominant trait). The husband’s mother had blue eyes. What percentage of their children could possibly have blue eyes?
Answer:
75%
Explanation:
The mom only carries the gene for blue eyes. The dad carries the gene for blue eyes, and the gene for brown eyes. So hypothetically speaking (because Punnet squares are only guesses/predictions) 75% of the kids could have blue eyes

Once food is chewed, the bolus is moved into the stomach for further digestion.
