It is a genus (which is greater than a species but lower than a family) of extinct lamp shells, called brachiopods.
Answer:
Frequency of BBBB genotype = 0.68
Frequency of BBBG genotype = 0.2
Frequency of BGBG genotype = 0.12
Explanation:
Genotype frequency = number of individuals of that genotype/ total number of individuals
In this population three types of individuals are present: blue, turquoise and green.
Frequency of BBBB genotype (blue) = 170/ ( 170 + 50 + 30)
= 170/250
= 0.68
Frequency of BBBG genotype (turquoise) = 50/250
= 0.2
Frequency of BGBG genotype (green) = 30/250
= 0.12
Answer:
Seafloor spreading occurs along mid-ocean ridges—large mountain ranges rising from the ocean floor. The Mid-Atlantic Ridge, for instance, separates the North American plate from the Eurasian plate, and the South American plate from the African plate.
Explanation:
For example driving cars, they release nitrogen and sulfur in the water vapor. This causes the water vapor to be more acidic. So then When the precipitation falls back to the Earth it comes down as acid rain.
Answer:
More branching or folds.
Explanation:
Adaptation may be defined as the ability of the organism to adapt and survive according to its environment. Physical, physiological and chemical changes occur in the body of organism for the adaptation process.
The evolution of the increase in the size of the animals might also changes their internal physiology. The lungs and digestive tract also evolved as the size of the organism get bigger. The lungs has the alveoli to increase the surface area and inhalation of more oxygen in the body. Digestive system has villi or folds that increases the surface area for digestion and absorption.
Thus, the answer is more branching or folds.
