For an organism to be considered as same species, it is important that their progeny can mate and produce viable offspring for generations. In this case, the mating of zebra and horse does not produce a fertile offspring, hence, their offspring cannot produce future generation, so, they cannot considered to be in same species.
Moreover, there are difference in the number of chromosome in between zebra and horse, and the zorse's number of chromosome is also different from the zebra and horse. In a species, the number of chromosomes must be same, so, this is also a factor, why they are not considered as a same species.

Answer:
Most ocean pollution begins on land.
Much of this runoff flows to the sea, carrying with it agricultural fertilizers and pesticides. Eighty percent of pollution to the marine environment comes from the land. One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff.
Answer:
Plastic pollution: The ocean is estimated to contain millions of tons of plastic debris, much of which comes from land-based sources.Chemical pollution: The ocean is also contaminated with a wide range of chemicals, including pesticides, herbicides, and industrial and household chemicals.Nutrient pollution: Excess nutrients, such as nitrogen and phosphorus, can enter the ocean from agricultural and urban runoff and contribute to the growth of harmful algal blooms.Oil pollution: Oil spills and other oil discharges into the water can have a negative effect on the animals and marine ecosystems there.

b. monomer.
c. disaccharide.
d. polysaccharide.
Glucose is a monomer, a molecule that can join together with other molecules to form a larger structure such as a polymer or polysaccharide.
Glucose is classified as a monomer. In the context of biochemistry, a monomer is a molecule that can join together with other molecules to form a larger complex, known as a polymer. Examples of polymers include proteins, nucleic acids, and polysaccharides. However, glucose itself is a simple sugar and acts as a building block for these larger structures. As such, it is a monomer, not a polymer or a polysaccharide. It is also not a disaccharide, which is a sugar composed of two monomers, such as sucrose (a disaccharide made of glucose and fructose).

Answer: B: False
Explanation: In the past, scientists may not have prioritized environmental concerns. However, with the rise of global warming and other environmental risks, modern-day scientists are deeply invested in understanding and mitigating the human impact on the environment. They are actively searching for solutions to minimize or eliminate these threats to human safety.
