Once starch in a person's diet has been broken down into _____, those subunits are absorbed in the small intestines.
Murrr4er [49]

Once starch in a person's diet has been broken down into monosaccharides those subunits are absorbed in the small intestines

Carbohydrates, also referred to as sugars, are a type of polymer. They are polymers whose subunits are linked together by glycosidic linkages that, when water is released, form a bond between two monomeric units. The amount of monomers that must come together to make a carbohydrate allows for the division of the carbohydrates into various groups. The monosaccharide, commonly known as simple sugars, is the most basic type of carbohydrate chain.

Since they exist as a single unit and are not connected to any other monosaccharides, these molecules are frequently referred to as the monomers of a carbohydrate chain.

To learn more about monosaccharides refer the link:

The mitotic spindle consists of two types of microtubules: kinetochore microtubules and nonkinetochore microtubules. In animal c
Blababa [14]

Answer:

The correct answer will be

1. Lengthen

2. Lengthen, shortens

3. Disassemble

Explanation:

There are three types of microtubules present during cell division: kinetochore, aster and polar microtubules.  

1. During prophase: all types of microtubules grow out at their positive(+) ends which functions to pull and push the sister chromatids apart towards opposite poles so they lengthen.

2. During anaphase : non-kinetochore microtubules- polar microtubules polymerization takes place at their (+) ends which causes the spindle fibres to move apart  while kinetochore microtubules which have been attached to the kinetochores of chromosomes shorten at their (+) ends and  motor proteins travel to (-) end because of which sister chromatids move towards the spindle poles.

3. During telophase: non-kinetochore microtubules depolymerize or disassembles.

Thus, 1. Lengthen, 2. Lengthen, shortens and 3. Disassemble are the correct options.

Does during meiosis the 2n mother cells produces n daughter cells
liq [111]

Yes. During meiosis Diploid (2n) mother cell produces fou haploid(n) daughter cell.

Explanation:

  • Meiosis is also known as Reduction division.
  • It is type of cell division by which a diploid mother cell produces haploid daughter cell.
  • It is termed as reduction division because the number of chromosomes are reduced to half in daughter cell.
  • Meiosis occurs only in sex cells to produce gametes.
  • Significance of meiosis lie in the fact that it reduces the number of  chromosome into half and thus helps to maintain the chromosomal number of the species in the zygote after fertilisation .
  • Meiosis has two steps : Meiosis I and Meiosis II. There is a time gap between two steps, called interkinesis.
  • Meiosis I involves replication , crossing over etc.
  • Meiosis II is similar to mitosis however, no DNA replication occurs prior to meiosis II and the DNA content is thus halved in Daughter cell.
