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.
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.

pls help i need answer asap! The digestive system is a group of organs working together to convert food into energy and basic nutrients that are transported throughout the body. Food passes through a long tube inside the body known as the alimentary canal, made up of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. Once food is chewed, the bolus is moved into the stomach for further digestion. Examine the Interconnections chart and select the body system that is responsible for moving the food from the start to the finish of the digestive system.

B) muscular system
C) integumentary system
D) cardiovascular system

What behavioral differences would you predict between the chicks treated with testosterone and chicks in each of the control groups.
Answer:
Throughout the clarification section below you can find a summary of the query.
Explanation:
Testosterone would be the masculinity compound or factor of the chick, compared to that same checking kids, behavioral improvements can be seen throughout testosterone-treated kids across two weeks.

Explanation:
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
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.

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.
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).

Imagine a population of moths. White moths are easier for birds to see and eat. Black moths blend into their surroundings, so they are less visible to birds than white moths. As a result, black moths are more likely to survive and reproduce, enabling the gene for black coloration to be passed on to the next generation. This increases the frequency of genes for black coloration in the population. Which evolutionary process does this scenario describe
Answer:
The correct answer is - natural selection.
Explanation:
Natural selection is a process of adapting according to the environmental change in order to survive and reproduce and increase their number. It is represented by Darwin for the first time. Natural selection leads to evolution.
In this case, White moths adapt according to the environment by increasing the population of black moths in order to blend with the surrounding and as the result, black moths are more likely to produce and survive and passed this trait to the next generation.

How does your nose filter the incoming air?
Answer:
Air enters through the nostrils of the nose and is partially filtered by the nose hairs, then flows into the nasal cavity. The nasal cavity is lined with epithelial tissue, containing blood vessels, which help warm the air; and secrete mucous, which further filters the air
