D - the theory of natural selection states that the population will be narrowed as "less fit" organisms die and "more fit" organisms survive, passing on their beneficial genes to offspring. Therefore, more organisms are born than can survive.
Milk packaging is designed to be attractive to the customer, give information, ease transport and to protect the product to maximize shelf life. Tetrapak cartons protect the product from light, air and microorganisms.
Answer:
The circulatory system comprises of blood vessels which help in removing carbon dioxide from the body. The carbon dioxide produced by the cells is collected by the capillaries where the carbon dioxide gets dissolved in the blood. This blood is carried to the heart via the veins. The heart pumps the deoxygenated blood to the lungs where gaseous exchange occurs between the blood capillaries and the alveoli of the lungs. When we exhale, the carbon dioxide is breathed out.
Answer:
Distinguishing between Similar Traits
Similar traits can be either homologous structures that share an embryonic origin or analogous structures that share a function.
LEARNING OBJECTIVES
Explain the difference between homologous and analogous structures
KEY TAKEAWAYSKey PointsOrganisms may be very closely related, even though they look quite different, due to a minor genetic change that caused a major morphological difference.Unrelated organisms may appear very similar because both organisms developed common adaptations that evolved within similar environmental conditions.To determine the phylogeny of an organism, scientists must determine whether a similarity is homologous or analogous.The advancement of DNA technology, the area of molecular systematics, describes the use of information on the molecular level, including DNA analysis.Key Termsanalogous: when similar similar physical features occur in organisms because of environmental constraints and not due to a close evolutionary relationshiphomologous: when similar physical features and genomes stem from developmental similarities that are based on evolutionphylogeny: the evolutionary history of an organismmolecular systematics: molecular phylogenetics is the analysis of hereditary molecular differences, mainly in DNA sequences, to gain information on an organism’s evolutionary relationships
Answer: The area of magnetic force around a magnet
Explanation: "A magnetic field is a vector field that describes the magnetic influence of electric charges in relative motion and magnetized materials. A charge that is moving parallel to a current of other charges experiences a force perpendicular to its own velocity." <em>*Wikipedia*. </em>
