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:
1. Mitotic cell division
Explanation:
Embryonic development is the formation of organisms that starts from the process of fertilization. The stages of development represent mitosis.
What is mitosis?Mitosis is a part of the cell cycle, that produces two identical nuclei and daughter cells from the division of the cell and replication of the parent cell.
From the diploid parent cell, two diploid daughter cells are produced in mitosis. This process is the first and the initial stage of embryonic development that initiates the growth and development of the embryo from the parent cell.
Therefore, option 1. mitosis is the process of embryonic development.

Answer:
Movement of the Asthenosphere
Explanation:
The Asthenosphere is the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur. This convention causes warmer magma in the earth's core to rise and cooler to fall and be heated again. The circular motion caused by this convection is what is thought to cause the Earth's crust to move.

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.
Answers
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
Gametas) Ch, ch, Ch, ch (hombre)

4/16 = 1/4 = 25% CcHh, Cataratas y huesos frágiles 4/16 = 1/4 = 25% ccHh, Ojos normales y huesos frágiles 4/16 = 1/4 = 25% Cchh, Cataratas y huesos normales 4/16 = 14 = 25% cchh, ojos normales y huesos normales
Which level of organization involves an organism’s use of the mouth, saliva, teeth, stomach, intestines, liver, and pancreas to break down food?
A. Cell.
B. Tissue.
C. Organ.
D. Organ system.
Answers
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.
