Plants and algae are the two groups of organisms
An egg is the organic vessel containing the zygote in which an animal embryo develops until it can survive on its own, at which point the animal hatches. An egg results from fertilization of an ovum. Most arthropods, vertebrates, and mollusks lay eggs, although some do not, such as scorpions and most mammals.
Reptile eggs, bird eggs, and monotreme eggs are laid out of water, and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a favorable temperature range (warm) while the embryo grows. When the embryo is adequately developed it hatches, i.e. breaks out of the egg's shell. Some embryos have a temporary egg tooth with which to crack, pip, or break the eggshell or covering.

The correct answer is b: cattle on rangeland. A point source of pollution occurs from a single identifiable and usually spatially narrow source. These sources of pollution are usually relatively easily to quantify and manage. In contrast, a non-point source of pollution, such as cattle on rangeland or irrigated agriculture, is variable on both spatial and temporal scales. These sources of pollution are difficult to quantify and manage.
Answer:
a. sexual dimorphism was developing over time in these species.
Explanation:
Sexual dimorphism refers to the presence of observable distinct phenotypic differences between the males and females of the same species. In humans, adult males have a larger larynx which is responsible for their deep voice than females. Females have a relatively smaller larynx. Therefore, a trend toward decreasing larynx size in adult females and increasing larynx size in adult males in fossils represents the development of sexual dimorphism in these species.
