Answer:The answer is diffusion.
Explanation: Unicellular organisms excrete waste by diffusion.
Unicellular organisms are organisms that have only one cell. They are called single cell organisms because all their life processes such as reproduction, feeding, digestion, and excretion, occur in only one cell. An example of unicellular organism is paramecium.
Diffusion is the inactive movement of molecules from the region of higher concentration to the region of lower concentration.
Nondisjunction is most likely responsible for the failure of a gamete to receive a copy of a particular chromosome.
What is non-disjunction?
When a pair of homologous chromosomes fails to segregate or separate at anaphase, both of the pair's chromosomes pass to the same daughter cell. This most likely happens during meiosis, but it can also happen during mitosis to create a mosaic individual. These are some potential causes of nondisjunction, while the exact cause or causes are unknown. Growing maternal age is linked to trisomy 21 and trisomy 18 fetuses and newborns, indicating that the mother's age may be a significant etiological component. Chromosomal structural defects such translocations and pericentric inversions might hinder chromosome pairing during meiosis and encourage nondisjunction.

Most chemical digestion and absorption of nutrients takes place in the _small intestine_.
All macronutrient (protein, carbohydrate, fat) breakdown into their basic subunits (monomers) is finalized in the small intestine. This is where all foodstuffs will meet the last set of enzymes and emolients/emulsifiers (dissolvers) to do the final breaking of bonds (chemical digestion). And it is therefore also in the small intestine that a vast blood supply allows a special circulatory route to absorb (pick up) these nutrients (sugars, amino acids, small fatty acids) via their tiny capillaries, and transport them to the liver for processing. This circuit is known as the Portal Venous System.
The most appropriate answer would be that a woman who is pregnant may consume up 200 g of caffeine because this will be safe.Therefore, it is evident that a smaller amount of caffeine is safe during pregnancy because a lot of caffeine has been found to increase seizures as well as penetrate freely to the placenta.This is dangerous and can cause harm to the unborn child.
