Answer:
Option B, a generation
Explanation:
A pedigree is a tree diagram that represents the relationships between different individuals based on certain facts and medical(genetic evolutionary) histories. Basically , the branches of the tree represents the generations which allows the researcher understand how certain genetic characteristics or traits are transmitted with in a family
Such as transmission of any genetic diseases from one generation to the other.
Hence, option B is correct
In the simulation, the brightness of the guppies is directly related to
how fast they are consumed by predators. This phenomenon is explained
simply and reflects natural selection. The brighter guppies are at a
selective disadvantage due to the ease with which predators are able to
spot them. The darker colored guppies are able to avoid predator better
so they live fore a longer time.

Answer:
The correct answer is - domain.
Explanation:
In a taxonomic system, all the organisms fall into three broad groups that comprise different kingdoms of the organisms. This group of taxa known as Domain and it is the broadest and most inclusive taxa of the taxonomic system. It includes three groups Archaea, bacteria and eukarya.
Archaea and bacteria were used to comprise in one group but due their differences archaea are divided into new group. These domains have all the organisms present on earth.
Answer:
D. The tubes allow water and nutrients to be transported throughout
the plant.
Explanation:
option D supports the description of the cells. The long , vertical tubes transport water and nutrients and are most likely xylem and phloem vessels.
option A is wrong since, chloroplasts inside the cell helps in absorbing sunlight.
option C is also wrong, because water loss is controlled by the stomata in the leaves and they are not long tubes.
option B could possibly be right but option D is better suited.
Answer:
Ionizing radiation comes from these main sources:
Nuclear reactions in the Earth's sun and stars in space.
Radioactive decay in the body's tissues and in the soil.
Radioactive decay of unstable elements in rocks, especially rocks that contain radium and release radon gas.
Other examples of ionizing radiation include alpha, beta, and gamma rays from radioactive decay.
