How do multiple alleles provide many different phenotypes for a trait

1 answer:

8 0

There are dominant and recessive alleles. when one allele from each parent combine, there are a couple different possibilities for traits. for example, whenever a parent gives off a dominant allele, you will automatically have that trait because it would have combined with another dominant allele, or it would have overpowered the other recessive alelle. you cam find these different combos by using a punnet square. but also, some traits, such as eyecolor, are determined by incomplete dominance, when the colors of your parents in their greenness combine in to a new color. or, you can have codominance when you have one of each eyecolor of your parents.

Which of the following statements is the most likely explanation for plant withering due to leaky membranes in cold temperatures

podryga [215]

Answer:

C. H+ ions do not accumulate inside the thylakoid, so ATP synthase makes too little ATP.

Explanation:

Plant withering refers to the virtual death of plant cells due to lack of food. During the light-dependent reactions of photosynthesis, ATP needed for the synthesis of sugar (food) is created in the thylakoid membrane of the CHLOROPLAST of plant cells.

In the light-dependent reaction, hydrogen ions (H+) builds up/accumulate in the thylakoid lumen to create an electrochemical or proton gradient i.e. a difference in the concentration of H+ ions across the membrane. The hydrogen ions passes through a protein complex called ATP synthase, which forms ATP from ADP (by adding phosphate group), from the energy generated by the electrochemical gradient formed as a result of hydrogen in (H+) build up.

Hence, a plant that possess leaky membrane due to the cold temperature will likely wither because H+ ions are not able to accumulate inside the thylakoid causing a proton gradient, so ATP synthase makes too little ATP.

La ecologia es la ciencia que estudia la materia inerte de un medio natural es falso verdadero

likoan [24]

Answer:

Falso

Explanation:

La ecología es la ciencia que estudia la interacción entre los seres vivos y el ecosistema. Esto incluye la interacción entre todos los factores tanto bióticos, o vivos, como abióticos, no vivos.

Por ejemplo, la ecología podría estudiar la manera en que un venado interactúa con su entorno: cual es su principal fuente de alimento, el rol que juega en el ecosistema, las adaptaciones que ha desarrollado para vivir en dicho entorno, etc.

Debido a que la materia inerte es considerada un factor abiótico o no vivo, esto no correspondería al área de la ecología. Por ende, este enunciado es falso.
