Answer:

The correct answer is: homologous chromosomes.

Explanation:

Diploid species like us humans have two sets of the same 23 chromosomes: 1 set of chromosomes is inherited from our mother, the other set we inherit from our father, making up a total of 46 chromosomes in every somatic cell (sexual cells have only one set of chromosomes - they're haploid).

<u>Two chromosomes are </u><u>homologous</u><u> when they belong to the same pair and have the same genetic information, although they can have a few variations</u>. These variations from one homologous chromosome to the other are called<em> alleles</em> and represent the different phenotypic variables that can result from the same gene. If these alleles are different from one another, only one of them will express itself (there are a few exceptions, like blood type) as the organism will be heterozygous for this trait; if the alleles are the same, the individual will be homozygous for the trait.

This is the basis for Mendelian inheritance.

Answer:

Microtubules have shapes like a spindle and are arranged to form centrosome and a cluster of such microtubules form centriole.

Explanation:

Microtubules are seen in eukaryotic cells to give shape and structure to the cells and they form part of the cytoskeleton. They are known to grow long and are dynamic. Centrosomes are known to be main microtubule that are found in animal cells. They are organelles that are made from the arrangement of clusters of microtubules. The centrioles are organized microtubules that actually help to serve as skeletal system of the cell. These centrioles  help to determine the locations of the nucleus.

Answer:

The correct answer is -  Rotate the types of crops grown.

Explanation:

Crop rotation is the practice of growing the different types of crops sequentially on the same field to improve nutrients in the soil for better soil health and helps in fighting pest and weed pressure.

Different crops required different nutrients and therefore, rotating crops helps to not exploiting the same nutrients again and again. Rotating crops also helps in removing weeds and pests as different weeds and different pests associate with different crops.
