The Vikings were able to effectively use their longboats because of the
following:
The boats moved swiftly and efficiently in the water making it easy to evade their enemies.The longboat rode high in the water, allowing it to sail further in the shallow water and transport the vikings closer to shore.The long boat was not only fast, but also light enough to be carried over land fortifying bridges.Vikings made use of the long boat because it was light weighted and the
people could carry it.
The light weight of the ship also ensured that it moved swiftly and was able
to sail in shallow waters.

Dad has blue eyes and Mom has blue eyes. Their daughter, Bonnie, has brown eyes. Is Bonnie adopted? Use the GENOTYPE of each parent to EXPLAIN your answer
Answer:
No, Her parents carried it from other family members because brown is dominant
Explanation:
hope this helps
No, Her parents carried it from other family members because brown is dominant Dad has blue eyes and Mom has blue eyes. Their daughter, Bonnie, has brown eyes.
What is a phenotype of eye color?The allele for green eyes is always dominant over the allele for blue eyes, which is always recessive. You will have brown eyes if at least one of your two copies is brown (Bb), which is what dominance signifies.The allele for brown eyes is the most dominant one and is always dominant over the other two alleles.
Geneticists refer to the various eye color gene variants as B for brown and b for blue, if your mom has blue eyes, your dad has brown eyes, and you have brown eyes.
Therefore, a quarter of the offspring will be born with blue eyes, and three-quarters will be born with brown eyes if both parents have brown eyes but also carry the gene for blue eyes.
Therefore, No, Her parents carried it from other family members because brown is dominant Dad has blue eyes and Mom has blue eyes. Their daughter, Bonnie, has brown eyes.

The fish shown here is normally found in a pond but is being studied in an aquarium. The amount of water and salt intake and excretion is measured as the fish maintains homeostasis. What scientific
question is most likely being asked based on the information in the model?
Based on the information in the question, we can infer that the question being asked is most likely "What mechanisms do fish use to maintain homeostasis in salt-water environments?".
What is homeostasis?Homeostasis is a series of regulatory processes by which an organism maintains core values (or range of values) necessary for everyday life.How to test the questionThe question is in the form of a hypothesis.This means that the scientist must first propose a possible solution to the question.Then, the scientist will make observations based on this question. In this case, it would seem the scientist has placed the fish into an environment that differs from its natural habitat, in order to observe how the fish maintains homeostasis.
Therefore, we can infer that the most likely question being asked is in regards to the way in which fish maintain homeostasis.

What's a recycling plant and how are electromagnets used there?
Answer:
A recycling plant is a factory for processing used or abandoned materials. The different types of recycling plants include those that process glass, metals, and paper back into raw materials. Other plants focus on items that require complicated recycling processes, such as concrete, electronic equipment and various plastics.
Electromagnets are used to lift and manoeuvre the crushed up ferrous materials or again to extract them from a pile of scrap. Ferrous materials are heavy and sharp but with the strength of the electromagnets they can be lifted and moved around with ease.
