The most likely reason that horses and mountain goats have hooves is that they have homologous structures because they share a common ancestor.
Hope this helps!
<span>In Integumentary system blood vessels are found in dermis and the blood vessels contract when the body is cold.
Dermis and epidermis are layers of the skin, dermis is the thick layer of tissues and it is present under the epidermis layer.
When we feel cold, our body supplies the warm blood to the skin. When contraction of blood vessels occurs, it reduces the flow of warm blood and reduces the heat loss. When we feel hot, blood vessels dilate.</span>
Hydrogen bonding is a interaction between two hydrogen atoms that is very essential for life on Earth. It is notoriously seen between water molecules, and it occurs when there is a slight disbalance in electrical charge between two Hydrogen atoms, and Oxygen atom that comprise water. This slight imbalance makes the Oxygen slightly more electronegative, and the two hydrogen atoms slightly more electropostive. The reason why water when spilled forms globules for this exact reasoning. The slightly positive charged hydrogen feels an electrostatic attraction to the Oxygen atom thus forming a strong bond. An interesting fact that comes from this electrical disbalance is that when salt is added to water, water is able to conduct electricity because of this disbalance in charge it can seperate the sodium chloride lattices into ions.
D) is the answer
Hope I helped XD
Here goes the correct sequence everyone...
- Fault line - <u> Very dark and thick line </u> .
- Contact line - <u> Slightly dark and thick line </u> .
- Axis fold - <u> Looks like a stubby T </u> .
- Strike and dip - <u> Very light and thin line </u> .
