Answer:
second image or B. Y
Explanation:
Potential energy is defined as the stored energy of an object when work is done against a force.
The second image in which yo-yo is ready to stretch out, represents the yo-yo with the most potential energy because the distance is highest from the ground and so yo-yo at this position will have highest gravitaional potential energy. The potential energy will be converted into kinetic energy when released in air.
Hence, the correct image is "second image" or "B. Y"
Answer:
-A decrease of honey population will very bad for the world, considering honey is where we get a third of our countries food.
-If we don't have honey, we could lose half of our diet.
-Honey bees pollinate over 75% flowering plaints and crop and without honey bees, we could lose a lot of them including fruits and nuts.
Answer:
D) anatomical features
Explanation:
The molecular systematics uses the data on the molecular structures to establish evolutionary relationships between the organisms. Techniques of DNA, RNA, and amino acid sequencing are used to compare the macromolecules of organisms. These studies provide information about the degree of relatedness among organisms. The closely related species share a higher degree of similarities in the sequences of these macromolecules. However, this branch of science does not include information about the anatomical and structural features to establish evolutionary relationships.
Chemical changes occur when bonds are broken and/or formed between molecules or atoms. This means that one substance with a certain set of properties (such as melting point, color, taste, etc) is turned into a different substance with different properties. ... One good example of a chemical change is burning a candle.
