Answer;
5. the flipper of a dolphin and the arm of a koala
Explanation;
Homologous structures are body structures that share a common origin, the degree at which these structures resemble each other can be used to infer the closeness of evolutionary relatedness.
-A homologous structure is an example of an organ or bone that appears in different animals, underlining anatomical commonalities demonstrating descent from a common ancestor. It's when very different animals have bones that appear very similar in form or function and seem to be related. For example; the flipper of a dolphin and the arm of a koala.
Answer:
The body uses osmosis by lowering the water potential near the skin by exerting a small amount of salt inside the sweat glands, this lowers the water potential inside the gland, and this causes water to move into the gland via osmosis as the water potential is higher outside the gland then within it.
Explanation:
The feature that you need to use in examining and make a
determination whether the skeletal remains in the pelvis is either male or
female is by analyzing its size and construction. It is because males have
larger pelvis bone and are robust elements compared to females who have smaller
and are light in terms of construction.
Answer:Major trends are electronegativity, ionization energy, electron affinity, atomic radius, and metallic character. The existence of these trends is due to the similarity in atomic structure of the elements in their group families or periods and because of the periodic nature of elements
