Which of the following statements comparing respiration in fish and in mammals is correct?
levacccp [35]

Answer: The following statements <em>comparing respiration in fish and in mammals</em> is correct:

  • The movement of the respiratory medium in mammals is bidirectional, but in fish it is unidirectional.

Explanation:

<u>Breathing </u>is the process by which living beings <em>exchange gases</em> with the external environment. It consists of the <u>entry of oxygen</u> into the body of a living being and the <u>exit of carbon dioxide</u> from it .

Active ventilation occurs if the animal produces the currents (of air or water) that flow to and from its respiratory membranes. It can be :

  • Unidirectional. (air or water is pumped onto the respiratory membrane in only one direction).
  • Bidirectional. (air or water is transported to the respiratory membrane and moves away from it through the same route like in the mammals).

life cycles of sexually producing organisms involve the alternation of haploid and diploid stages true/false
kolbaska11 [484]

Answer:

True

Explanation:

<em>The life cycles of sexually producing organisms generally involve alternation between the haploid and diploid generations.</em>

<u>Sexual reproduction involves the fusion of gametes - fertilization. The gametes are haploid (n) and are usually formed by the reductional division (meiosis) of diploid (2n) sex cells. </u>

Haploid gametes represent the haploid stage of the life cycles of sexually reproducing organisms.  During fertilization, the male and female gametes fuse together to form a diploid zygote. The zygote then continues to divide equationally (mitosis) and differentiates to give rise to a baby and eventually to either male or female adult organism.

-Dominant- [34]

The best technique for your mother is that she uses each word in a sentence to give it a meaning, and remember it better (option 2).

Elaborative rehearsal is a common technique used to remember information in a long-term way. Due to this, this technique can be used to move information from short-term memory to long-term memory.

In this technique, the main purpose is to associate the new information with something you already know. In learning new words, this can include:

  • Associating new words to images.
  • Creating examples of sentences.
  • Associating a new word to a synonym you already know.

In this context, the technique that is part of elaborative rehearsal is using the word in a sentence (option 2).
