A new dog breed is less likely to cause an allergic reaction in humans. Which statement explains how artificial selection led to the development of this desirable trait?
Different dogs were bred with other animal species such as cats to introduce new nonallergic traits to obtain the new dog breed.
Different dogs were bred with other animal species such as cats to introduce new nonallergic traits to obtain the new dog breed.
Different dog breeds were chosen for nonallergic traits and bred with each other to obtain the new dog breed.
Dogs were trained over generations to not produce and release proteins that cause allergic reactions in humans to obtain the new dog breed.
Dogs were kept outdoors over generations to build up a natural defense against allergens in the environment to obtain the new dog breed.
Answer:it is c
Explanation:cuz it is
Answer:
C
Explanation:
Because they would test the dogs for traits and then selectively breed them
How is natural selection similar to selective breeding? How is natural selection different from selective breeding?
Answer:
Natural selection and selective breeding can both cause changes in animals and plants.the difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. for this reason selective breeding is sometimes called artificial selection.

Most populations do not experience: ____ va) exponential growth b) Linear growth c) Resources d) Competition
Answer:
Most populations do not experience: a) exponential growth
Explanation:
Populations that experience exponential growth models show an increase in proportion to their size. The increase in the population size depends on the individual´s reproduction rate: a population that grows at constant exponential rate gains individuals faster as the population increases in size.
This model states that populations live in an environment with unlimited resource availability, so the density factor does not influence population growth. There is no density-dependence effect nor competition for resources. Natality and mortality rate do not depend on density. There is a constant growth rate per capita, and it is proportional to the population size.
Exponential growth is hardly seen in nature due to its characteristics.
Almost every environment shows a carrying capacity point. Carrying capacity is the capability of the environment to support a population. Commonly environments have limited resources and space, and as the population grows, competition increases too. The per capita growth rate decreases as population size increases. Finally, the population reaches the maximum point of carrying capacity, delimited by available resources, such as food or space.
The carrying capacity might be affected by limiting factors, which might be a result of the population density (for example, competition) or might be density-independent. This last case refers to dense-independent factors, and among these, we can mention human impact or natural disasters (fires, volcanic eruption, flooding).
Only a few species can experience exponential growth, such as bacterias.

Dos condiciones anormales en el hombre, que son las cataratas y la fragilidad de huesos son debidas a alelos dominantes. Un hombre con cataratas y huesos normales cuyo padre tenía ojos normales, se casó con una mujer sin cataratas pero con huesos frágiles, cuyo padre tenía huesos normales. Calcula la probabilidad de: a) Tener un hijo completamente normal b) Que tenga cataratas y huesos normales c) Que tenga ojos normales y huesos frágiles d) Que padezca ambas enfermedades.
Answer:
La probabilidad de:
a) Tener un hijo completamente normal, cchh = 25%
b) Que tenga cataratas y huesos normales C-hh = 25%
c) Que tenga ojos normales y huesos frágiles ccH- = 25%
d) Que padezca ambas enfermedades C-H- = 25%.
Explanation:
Datos disponibles:
Alelo dominante C expresa cataratasAlelo recesivo c expresa visión normalAlelo dominante H expresa fragilidad de huesosAlelo recesivo h expresa huesos normalesLos posibles genotipos para cada característica entonces son:
CC y Cc ----> Cataratascc -------------> Ojos normalesHH y Hh ----> Huesos frágileshh--------------> Huesos normalesSabiendo esto, podemos deducir los genotipos del hombre y la mujer involucrados en la cruza.
Hombre con cataratas y huesos normales, tiene genotipo C-hhPadre del hombre tiene ojos normales, ccEl padre del hombre es homocigota recesivo, expresando ojos normales. Esto significa que solo pudo heredarle al hijo (el hombre) un alelo recesivo, c. Pero el hombre expresa cataratas, lo que significa que porta también un alelo dominante, probablemente heredado de la madre. Entonces el hombre es heterocigota para el tipo de ojos. Y puesto que tiene huesos normales, sabemos que es homocigota recesivo para esta característica.
Genotipo del Hombre: Cchh
Mujer sin cataratas y huesos frágiles, tiene genotipo ccH-Padre de la mujer con huesos normales, hhEl padre de la mujer tiene huesos normales, implicando que su genotipo es homocigota recesivo y que solo puede heredarle a la progenie alelos recesivos. La mujer tiene huesos frágiles, lo que supone que heredó el alelo dominante de su madre. Puesto que recibió un alelo dominante de la madre y uno recesivo del padre, la mujer es entonces heterocigota para la característica en cuestión. Ella también tiene visión normal, lo que significa que su genotipo para esta característica es homocigota recesivo.
Genotipo de la mujer: ccHh
Sabiendo los genotipos de ambos integrantes de la pareja, podemos realizar la cruza:
Cruza: Hombre x Mujer
Parentales) Cchh x ccHh

A biologist wants to measure the effect of gene flow between populations. Which of the following investigations will allow her to accomplish this goal?
A)An investigation that determines a change in allelic frequency of a wolf population by theimmigration of a wolf from another population.
B)An investigation that determines the amount of time it takes for genes from a bee to transfer to the flower it fertilizes.
C)An investigation that determines the causes of mutations in genes that one species of guinea pig transfer to another species of guinea pig.
D)An investigation that determines the rate at which an antibiotic prevents a virus from transferring genes to a cat.
Answer:
B
Explanation:
Cause I say so
The investigation that will allow a biologist to measure the effect of gene flow between populations is that a change in allelic frequency of a wolf population by the immigration of a wolf from another population. Thus, the correct option for this question is A.
What is Population?A population may be defined as a group of individuals belonging to the same species living in the same area at a given time. The size, density, abundance, birth rate, death rate, dispersal, etc. are categorized as the characteristics of a population. These characteristics are known as demographic factors.
According to the context of this question, the process of gene flow can be determined by collating allele frequencies of populations. With this mechanism, if the two populations have increased variation in their gene pool, it expresses a lesser amount of gene flow because gene flow increases homogeneity among different populations.
Therefore, the correct option for this question is A.

The level of organization involves an organism’s use of the mouth, saliva, teeth, stomach, intestines, liver, and pancreas to break down food in the organ system. The correct option is D.
What is the organ system?An organ system is a collection of organs that cooperate to carry out a certain task in the body of an organism. Organs, which are self-contained collections of tissues like the heart that cooperate to carry out a single function, are present in the majority of animals and plants.
The human body is composed of 11 primary organ systems. These include the reproductive, integumentary, skeletal, muscular, nervous, endocrine, circulatory, lymphatic, respiratory, digestive, and urinary systems.
Organ systems are collections of organs that cooperate to carry out a task for the body they are a part of. They can aid in gas exchange, waste removal, nutrient acquisition and transportation, illness sensing, and disease protection for the body.
Therefore, the correct option is the D. Organ system.
