Why is it necessary to reduce the number of chromosomes in gametes, but not in other cells

2 answers:

The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.

Hope this helps:)

Answer:

The reduction of chromosomes in the gametes is necessary to make sexual reproduction possible, in which each parent contributes half of their chromosomes and in fertilization a cell with the complete amount of chromosomes is produced, the zygote.

Explanation:

The reduction of chromosomes to form gametes is done by meiosis, a reductive cell division. Sex cells or gametes are haploid cells, i.e. with half the chromosome charge, as each parent must contribute a gamete in the reproductive process.

The union of the parents' gametes is called fertilization and its product is the zygote, whose chromosome charge is complete or diploid.

<u>For a diploid zygote to be formed, it is necessary for the sex cells or gametes to be haploid, or with half of the chromosomes of the species.</u>.

The following phase of meiosis then put them in the correct order

MrRissso [65]

Answer:

The correct order is

Prophase l , Metaphase l, Anaphase I, Telophase l, Prophase ll, Metaphase II, Telophase ll / Cytokinesis ll

Explanation:

In Meiosis there are total two phases - Meiosis I and Meiosis II and each phase consists of total six sub phases which are as follows -

Meiosis I

1. Prophase I

2. Prometaphase I

3. Metaphase I

4. Anaphase I

5. Telophase I

6. Cytokinesis I

Meiosis II

1. Prophase II

2. Prometaphase II

3. Metaphase II

4. Anaphase II

5. Telophase II

6. Cytokinesis II

Hence the correct order is

Prophase l , Metaphase l, Anaphase I, Telophase l, Prophase ll, Metaphase II, Telophase ll / Cytokinesis ll

You observe a tissue under the microscope and see intercalated discs between adjacent cells. which tissue are you observing

Monica [59]

The correct answer is a muscle tissue, more precisely cardiac muscle tissue. <span>Cardiac muscle tissue consists of individual cardiomyocytes (heart muscle cells) which are connected by intercalated discs to work as a single functional organ. The function of intercalated discs is to support synchronized contraction of cardiac muscle.</span>

Estas de acuerdo con la aplicación del principio de la física en ecología:¨la energía no desaparece ni se destruye, solo se tran

saveliy_v [14]

Answer:

Esta afirmación es correcta ya que la ley de conservación de la energía es también aplicable a sistemas vivos

Explanation:

La ley de la conservación de la energía (la cual es la primera ley de la termodinámica) indica que la energía no se puede crear ni se puede destruir, solamente se transforma, de un tipo a otro. La ley de la conservación de la energía es de vital importancia para entender la existencia del mundo natural. En ecología, la energía fluye de un nivel trófico a otro en forma de biomasa, es decir, dentro de la cadena alimentaria. Esta energía no se puede crear ni destruir sino que es almacenada en los organismos, los cuales representan sistemas abiertos que intercambian materia y energía con el medio. Una vez dentro del organismo, una parte de esta energía es transformada (en plantas, por ejemplo, la energía es convertida en enlaces químicos durante la síntesis de carbohidratos), mientras que otra parte de la energía se elimina al exterior (por ejemplo, se disipa en forma de calor), pero la energía no se crea ni se destruye.
