Answer:
The correct option is C.
Explanation:
There are three modes of heat conduction, these are conduction, convection and radiation. Heat transfer by conduction usually involves the movement of heat through solid substances. For instance, in the scenario given in this question, the warm surface is the solid substance through which heat is passed to the insects' bodies. Thus, conduction requires direct contact.
Heat transfer by convection method usually involves the movement of heat through liquids or gases while radiation can occur in vacuum.
Let "r" stand for the recessive red hair trait. A person with red hair must have a genotype of "rr" ( one from each parent) in order to have red hair( red hair being the phenotype).
Let "B" stand for brown hair and "b" stand for not brown hair. A person with brown hair can have a genotype of "Bb" or "BB" and have a phenotype of Brown hair. This is becasue brown hair "B" is the dominant trait.
Answer:
Explanation:
Scientists use Taxonomy, the science of classifying living things, in order to make sense of biodiversity and how living things are related. For example, the classification of species is important in light of a changing environment because it helps scientists keep track of endangered species and what new species were formed because of the environmental change.
Answer:
Explanation:
We recognize that total occurrence equals new cases of disease over time divided by the number of people at risk at the onset.
Mathematically:
Given that:
Number of the population at risk = 1000 individuals
New cases during Jan 1 - Dec 31 = 60 because;
At 20 occurred on June 30 & 40 on Sept. 30) & no new cases were identified after that:
∴
7. Stress is the force applied to a rock, which may cause deformation of the rock. There are three major types of stress and go along with the three types of plate boundaries; Compression stress is common at convergent boundaries, tension stress at divergent boundaries, and the shear stress at transform boundaries. In this case the rocks have undergone tensional stresses.
8. Horst is a raised fault block bounded by normal faults. A horst is a raised block of the Earth's crust that has lifted, or has remained stationary, while the land on either side (garben) has subsided. Therefore the structure labeled A in the diagram is Horst.
9. A Graben; it is a valley with a distinct escarpment on each side caused by the displacement of a block downward. It often occurs side by side with the horsts. Horst and Graben structures indicate tensional forces and crustal stretching. Therefore, the structure labeled B is Graben.
