Answer:

6 chromosomes

Explanation:

Leni [432]3 years ago

Answer:

The gametes or sex cells produced by the organism will have 6 chromosomes if the organism has 12 chromosomes.

Explanation:

The diploid organism has all chromosomes in pairs, one chromosome inherited from male parent & another chromosome in the pair is inherited from the female parent. If an organism has 12 chromosomes, it has 6 different types of chromosomes, differing from one another in length, the position of centromeres and genes present on these. Six different types of chromosomes constitute a haploid set of chromosomes. Two chromosomes of the same type are called homologous chromosomes and these constitute a homologous pair. The cells producing sex cells or gametes undergo meiosis (reduction division) so that each gamete contains only one chromosome of a homologous pair. The gametes are haploid, having half the number of cells as compared to somatic cells.

Hope this helps have a great day/night! :}

Komok [63]

Answer:

c

Explanation:

Random distribution of the Isopods should be 50/50 in A and B.

Chi-square = \frac{(O - E)^2}{E} where O = observed frequency and E = expected frequency

Chamber         O                    E             Chi-square

  A                   18                   10             \frac{(18 - 10)^2}{10} = 6.4

  B                    2                    10             \frac{(2 - 10)^2}{10} = 6.4

<em>Total Chi-square </em>= 6.4 + 6.4 = 12.8

<em>Degree of freedom</em> = 2 - 1 = 1

<em>Tabulated Chi-square</em> (α = 0.05) = 3.8415

The calculated Chi-square exceeds the critical value, hence, it is significant and not due to random.

<em>The correct option is </em><em>c</em><em>.</em>

What colors of light are absorbed? Which color is not absorbed?
erastovalidia [21]

Answer:

All colour except which is already present in the body.

Explanation:

The plant leaf has green colour so the plant absorb all the colour except green. The presence of green colour causes reflection of green colour so that's why we can see the green colour of the leaves. Every material or substance have a specific colour which can be seen when they absorb all light except the colour which is already present in it so we can say that that colour is not absorbed by the body which is already present in it.
