Why do plants require oxygen?

Biology
1 answer:
Luden [163]3 years ago
3 0

Answer:

Plants need oxygen to survive, and plant cells are constantly using oxygen. Under certain circumstances, plant cells need to take in more oxygen from the air than they generate themselves.

Which pair of terms most accurately describes life history traits for a stable population of wolves? A. semelparous; r -selected
Lera25 [3.4K]

The correct option is (D) iteroparous; K -selected

Iteroparous organisms are the organisms that reproduce multiple times.

<h3>What is Semelparity and Iteroparity?</h3>
  • Semelparity and iteroparity are the two different reproductive strategies available to living beings.
  • Iteroparous species have multiple reproductive cycles throughout their lifetimes, while semelparous species have just one reproductive cycle before they die.
  • Death that occurs after reproduction is part of a bigger strategy in really semelparous animals that also entails maximizing reproduction at the expense of future survival.
  • There will always be some iteroparous individuals who die between their first and second reproductive episodes, but unless they exhibit symptoms of a state of programmed death after reproduction, they are not termed semelparous.

An organism has two types of cells: diploid somatic cells and haploid gametes. How does this organism reproduce? A. Sexually B.
kenny6666 [7]

Answer:

A. sexually

Explanation:

The organism has haploid gametes. Human sex cells (egg and sperm cells) contain a single set of each chromosome, making them haploid. During fertilization, the organism acquires a set of chromosomes from each parent, making it a diploid (two sets of each chromosome) zygote.

Hope this helps.

Andre45 [30]

Answer:

La reproducción sexual consisten en la unión de dos gametos uno femenino y otro masculino, para formar un nuevo individuo con características provenientes de ambos progenitores. Los gametos son células especializadas que se forman por un proceso meiótico y tienen en su núcleo la mitad de la información genética de un organismo, por lo que reciben el nombre de células haploides de manera que cuando se une sus cromosomas se forman células diploides característico de la especie. La característica más importante de este tipo de reproducción es la variación genética que implica que los descendientes tengan características de sus dos progenitores, por lo que son diferentes a ellos. El proceso en el que se une las células sexuales se le conoce como fecundación. En los animales esta pude ser interna o externa.

Explanation:

Los gametos (óvulos y espermatozoides) son células germinales especializadas que se desarrollan a partir de un proceso llamado gametogénesis (espermatogénesis en machos y ovogénesis en hembras). El proceso de gametogénesis implica un tipo de división celular llamado 'meiosis' donde la cantidad de cromosomas se reduce a la mitad. En humanos, el número cromosómico diploide (2n) de 46 cromosomas se reduce a un número haploide (n) de 23 cromosomas. La fecundación es el proceso por el cual los gametos se fusionan durante la reproducción sexual para producir un cigoto diploide. En la reproducción sexual, el aumento de la variación genética en la progenie es un resultado de tres procesos diferentes: la unión aleatoria entre gametos durante la fecundación, la distribución independiente de los cromosomas durante la gametogénesis y el entrecruzamiento (recombinación o crossing over) entre cromátidas de cromosomas homólogos durante la meiosis. Finalmente, en animales, la fecundación puede ser interna, la cual se produce mediante la unión de los gametos dentro del cuerpo de la hembra (por ejemplo, gallina, leona, cebra, etc.), o fecundación externa, donde la fusión de gametos se produce en el ambiente externo (por ejemplo en peces, sapos, ranas, etc.).
