Explanation:
In addition, in meiosis I, the chromosomal number is reduced from diploid (2n) to haploid (n) during this process. ... In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23).
The question is incomplete as it misses the options which are:
Cancer cells do not exhibit density dependent inhibition
Cancer cells do not require growth factors
Cancer cells do not exhibit anchorage dependence
Cancer cells ignore typical cell cycle checkpoints
Answer:
The correct answer will be option- Cancer cells do not exhibit anchorage dependence
Explanation:
A cell becomes tumour forming cell or cancerous cell when the cell undergoes some mutation in the DNA which causes uncontrolled cell division without differentiation.
As a result of the mutation, these cancerous cells show various properties which are present in the normal cells nut absent in cancerous cells like the cancerous cells lack the anchorage dependence.
Anchorage dependence is the property of the cells or the group of cells in which the cells maintain their adherence to the other layer of cells to communicate with each other.
Thus, the cancerous cells lack the anchorage dependence
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.

Answer:
More branching or folds.
Explanation:
Adaptation may be defined as the ability of the organism to adapt and survive according to its environment. Physical, physiological and chemical changes occur in the body of organism for the adaptation process.
The evolution of the increase in the size of the animals might also changes their internal physiology. The lungs and digestive tract also evolved as the size of the organism get bigger. The lungs has the alveoli to increase the surface area and inhalation of more oxygen in the body. Digestive system has villi or folds that increases the surface area for digestion and absorption.
Thus, the answer is more branching or folds.
