Explain how the stomach Depends on other body systems to carry out its role in breaking down food molecules.
denis-greek [22]
The whole body works together, as a “team.”If one of the parts of the body won’t work together as a team, everything will get messed up. The stomach muscles churn and mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces. An acidic environment is needed for the digestion that takes place in the stomach.

kicyunya [14]

Muscular exercise presents a dramatic test of the body's homeostatic control systems because it results in large amounts of heat production.

Homeostatic control systems- A body's physiological ability to maintain a steady internal environment in response to changes in the external environment is known as homeostasis.

Heat Production- The term "thermogenesis" refers to the process through which energy is lost by producing heat with specialization.

Energy- In biology, cells frequently store energy in macromolecules, especially lipids and carbohydrates (sugars). When chemical bonds are formed, such as during the redox reactions of cellular aerobic respiration, energy is released.

Redox Reactions- A reaction that happens when an oxidizing material and a reducing substance come into contact.

Meiosis does PMAT twice! That means there is a prophase I and a prophase 2. There is a metaphase1 and metaphase 2. Etc... How wo
Gennadij [26K]
<h3><u>Answer;</u></h3>

In metaphase I, the chromosome tetrads align on metaphase plate while in metaphase II, chromosomes align on metaphase plate as they are in mitosis with only sister chromatids.

<h3><u>Explanation;</u></h3>
  • Meiosis is a form of cell division that halves number of chromosomes when forming specialized reproductive cells such as gametes .
  • Meiosis occurs in two phases, namely; meiosis I and meiosis II. During homologous pairs of chromosomes align on the equatorial plane at the center of the cell.
  • During metaphase II, the spindle fibers connect to the kinetochore of each sister chromatid. The chromosomes align at the equatorial plane, which is rotated 90° compared to the equatorial plane in meiosis I.
