The current understanding of dark matter is largely theoretical due to its nature of not directly interacting with electromagnetism. It can be inferred to exist due to its gravitational effects, representing about 27% of the universe's mass-energy composition. The key candidate for it is Weakly Interacting Massive Particles, suggested by the Supersymmetry theory.
Our current understanding of the nature of dark matter is largely theoretical, as dark matter does not interact with the electromagnetic force and cannot be seen directly with telescopes. However, it is inferred to exist due to its gravitational effects on galaxies and galaxy clusters. Dark matter constitutes about 27% of the universe's mass-energy composition, vastly outweighing ordinary matter. The leading candidate for dark matter is currently the Weakly Interacting Massive Particles, or WIMPs. The existence of WIMPs is suggested by the Supersymmetry theory in particle physics, and several experiments are ongoing to detect WIMPs directly.

Answer:
The iodine reacted with the potato to form a new substance.
A child with a bloated belly, thin hair, and an inability to concentrate may be suffering from malnutrition. Malnutrition refers to a state of inadequate nutrition, either due to insufficient intake of essential nutrients or poor absorption and utilization of nutrients by the body. Malnutrition can result in various symptoms such as a bloated belly, thin hair, and difficulty concentrating.
A child with a bloated belly, thin hair, and an inability to concentrate may be suffering from malnutrition. Malnutrition refers to a state of inadequate nutrition, either due to insufficient intake of essential nutrients or poor absorption and utilization of nutrients by the body. Malnutrition can result in various symptoms such as a bloated belly, thin hair, and difficulty concentrating.
There are different types of malnutrition, including protein-energy malnutrition, which is caused by a lack of calories and protein, and micronutrient deficiencies, which result from a lack of essential vitamins and minerals. Malnutrition can have serious health consequences and can impair physical and cognitive development.
It is important for individuals to have a balanced and nutritious diet that provides all the necessary nutrients for proper growth and development. If a child is showing symptoms of malnutrition, it is crucial to seek medical attention and address the underlying causes.

- increased number of chromosomes in the offspring
- the appearance of new phenotypes in the offspring
- possible harmful mutations from cross-over errors
Answer:
B. increased number of chromosomes in the offspring.
Explanation:
Crossing over may cause chromosomes to lose or gain segments, but the overall number would not change.
Answer:
Over the years, greater controversy has arisen over environmental issues as the issues addressed have become more complex and less easily identifiable.
Explanation:
