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.
Answer:
Calcium also shares the same fourth period in the periodic table in which potassium present. The size of the atomic radius decreases from left to right in the period from left to right. Potassium present left to the calcium in the fourth period.
The reason for the decrease in the atomic radius due to the fact though electrons and protons increases but the valence shell remains the same from moving from left to right, therefore, as the net charge increases with the increase in the electrons result in shrinking of the valence shell and resulting in the decrease of the size of the atom.
Answer:
The correct answer is a. donates hydrogen ions to solutions
Explanation:
There are many definitions of what acid is, but the most common one is that an acid donates hydrogen (+) when it dissociates in solutions. Adding hydrogen or (+) to a solution will lower the pH value and then it will make the solution more acidic in the pH range.
