Answer:
You have not consumed lactose from dairy recently
Explanation:
According to the diagram, there is a represssor element in the regulatory region of the operon. This repressor is blocking the RNA polymerase, that is bound to its promoter region upstream of the genes, from transcription. The repressor is mostly the lac repressor that switches of the operon in the absence of lactose.
While giving birth to her infant during labor, the safest and the most effective pushing technique taught to a woman during contractions is grasping knees, head elevated and breathing out.
During labor, it is very important for the mother to keep breathing. If she holds her breath, it will put pressure on the vena cava and lead to a reduction in the blood return. The head is kept elevated and the back is rounded which aids the abdominal muscles to help the uterus to push the baby out. Grasping the knees also helps in pushing and encouraging the movement of the infant outside the body.

Answer:
C.) crystalline solids
Explanation:
The solid materials may be crystalline or amorphous. The concept of crystal structure is related to the organization of atoms in a geometrical form. Crystalline structures are present in various materials, where atoms distributed within their structure form a network called the crystalline lattice. Therefore, crystalline structures have salts, metals and most minerals. Crystalline structures are formed by unit cells that are their basic unit, as they constitute the smallest set of associated atoms found in a crystalline structure.
The molecules of the crystalline structures can have two types of bonds, the directional ones, which include the covalent and dipole dipole and the non-directional ones where the metallic, ionic, van der Walls bonds. When formed by ionic compounds, these crystalline structures can result in crystalline solids.
Answer:
The skull is from a fossil skull of Styracosaurus - a horned dinosaur.
Explanation:
This skull image is the skull of a Styracosaurus dinosaur who was a huge dinosaur almost 5 meters or more with the horned present on the skull. This is a fossil skull representation from the fossils.
Styracosaurus was present 75 million years ago during the Cretaceous period who was a completely herbivorous ceratopsian dinosaur.
Thus, the skull is from a fossil skull of Styracosaurus - a horned dinosaur.
