Answer:
To find a mineral deposit, geologists study the geology of a lot of places. They then go to a spot where that type of mineral deposit could be found. They test the properties of the soil and rocks. They look at the chemistry and the physical properties.
Explanation:
The correct answer is option A. They either match up with a receptor molecule on the surface of the cell or enter the cell through the membrane.
The intercellular signals are the signals, which transfer the signals from one cell to the another and the intracellular signals are those signals, which carries message within the cell.
The intercellular signals may or may not be transferred through the gap junctions. The chemical signals are one of the type of the cell signals. The chemical signalling molecules generally have a receptor on the cells, where these molecules can bind and can be cause the activation of the cell. The chemical signals can also enter into the cells through active transport and facilitated diffusion. So, these type of transports does not go through the Gap junction.
Answer: The extinction of dinosaurs will lead to increase in the prey which they used to consume before extinction.
Explanation:
Many years ago the dinosaurs used to dominate on earth as large mammals. They were plant eater herbivores and animal consumer carnivores. After the extinction of dinosaurs the ecological balance got disturbed. Flowering plants dominated the earth. The large and massive non-bird dinosaurs died but the bird like dinosaurs survived and they passed their traits to some lineages of modern birds.

Some bones develop within sheet like layers of connective tissue which are called intramembranous bones whereas the bones that are develop from a model of hyaline cartilage and are called endochondral bones.
<h3>Formation of
intramembranous bones and endochondral bones</h3>
Endochondral ossification involves the replacement of hyaline cartilage with bony tissue which leads to the formation of endochondral bones whereas, intramembranous ossification refers to the replacement of sheet-like connective tissue membranes with bony tissue which results in the formation of intramembranous bones.
