Answer:
Explanation:
Mendel four postulate is Principles of Paired Factors, Principle of Dominance, Law of Segregation which is Mendels First Law of Inheritance and Law of Independent Assortment which is Mendel’s Second Law of Inheritance.
The six possible outcome are,
3. Alleles segregate from each other during gamete formation at anaphase I gene assorts independent of each other during gametes formation.
4. Some genes have dominant and recessive alleles. Allele of a gene can either be dominant or recessive in its form
7. Unit factors occur in pairs , allele of a gene occur in pair
Dominant alleles can become codominant alleles during mitosis, when two allele both finds expression in the phenotype of an organism they are codominant
8. One gene pair separates independently from other gene pairs independent assessment of gene.
5. Different gene pairs on nonhomologous chromosomes will separate independently from each other during meiosis.
External respiration (correct answer) involves the exchange of oxygen and carbon dioxide within the environment.
The exchange of wastes through the skin is just called excretion by sweating.
There is no exchange of nutrients that occur in the lungs but rather absorption of nutrients is the function of the gastrointestinal tract.
The exchange of oxygen and carbon dioxide within the cell is called cellular respiration and involves carrying oxygen from the blood to the cell then the cell uses it as the final electron acceptor in the electron transport chain. The metabolic wastes of the cell, primarily carbon dioxide, goes now to the bloodstream to be exchanged for oxygen in the lungs.
Can please provide the options.
Answer:
En los seres vivos acuáticos el oxigeno es tomado del <u><em>agua</em></u> y penetra a la célula por el fenómeno de <em><u>respiración branquial.</u></em>
Explanation:
La respiración es el proceso mediante el cual los seres vivos obtienen oxígeno. Es decir, la respiración implica el reemplazo del dióxido de carbono en los pulmones por oxígeno del aire, y puede ser pulmonar, branquial, traqueal o cutánea.
La respiración branquial es un tipo de respiración propia de la mayoría de los animales acuáticos y se lleva a cabo en las branquias, unas estructuras con forma de láminas que contienen vasos sanguíneos. Los animales acuáticos dispone de estos órganos que permiten absorber el oxígeno que se encuentra en el agua y eliminar el dióxido de carbono.
El agua que entra por la boca y circula por las branquias, donde el oxígeno es absorbido, pasa a la sangre y es transportado a todo el cuerpo donde se produce una respiración celular.
Es decir, <em><u>en los seres vivos acuáticos el oxigeno es tomado del agua y penetra a la célula por el fenómeno de respiración branquial.</u></em>
