Answer: The correct answer is- A. Chromosome numbers vary widely.

Chromosome can be described as thread like structure that is composed of DNA ( deoxyribonucleic acid) and possesses genes ( segment of DNA coding for a particular protein) on it.

Eukaryotic cells ( such as plant cell, animal cell) have variable number of chromosomes.

For instance, human beings have 23 pairs of chromosomes whereas it is different in plants depending on the species.

Thus, A) is the right answer.

in what way are heterotrophs dependent on photosynthesis by autotrophs (explain at a 6th grade level)
aleksley [76]
Hello! Autotrophs make their own food (plants) and heterotrophs consume other organisms for energy (consumers.) Autotrophs use the process of photosynthesis to produce the oxygen as one of its products. Heterotrophs use the oxygen produced by the autotrophs to perform cellular respiration, which releases carbon dioxide that plants use; it's a balanced cycle. Hope this helps!

¿Que aspecto debemos considerar para desidir el uso mas adecuado de lagunos materiales en la satisfacción de necesidades humanas
umka21 [38]

Answer:

El efecto del material sobre el medio ambiente es el aspecto a considerar.

Explicación:

Se debe verificar la estructura química del material o de qué elementos se forma un material para conocer el efecto de estos materiales en la salud y el medio ambiente de las personas. Si los materiales no afectan el medio ambiente y la salud humana, el ser humano puede utilizarlos para satisfacer sus necesidades. Si el material se forma a partir de elementos tóxicos o elementos que no se descomponen por microbios, entonces este tipo de materiales son peligrosos tanto para la salud humana como para el medio ambiente porque estos materiales contaminan el medio ambiente y debido a esta contaminación la salud humana se ve gravemente afectada.

When studying animal behavior, the distribution of organisms within a choice chamber can be studied to identify animal preferenc
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>
