1. Calcium carbonate minerals are the building blocks for the skeletons and shells of mini marine organisms. It is important to ocean creatures because they make their shells out of this material. Examples of animal products that are primarily of calcium carbonate include seashells, egg shells, pearls, and notably coral
This is a theory because this has been proven by scientists years ago. The evidences to prove this theory were shown.
hope this helps!!! :) Pls mark me BRAINLIEST! :)
Answer:
Explanation:
biotic factors are the living components of an ecosystem (producers, consumers, decomposers). They all have some effect on population dynamics, producers (plants) are eaten and can make clean air, consumers (ex. ants, badgers, bears, fish, humans) rely on producers for food, and decomposers (bacteria, earthworms, fungi, flies) decompose things like dead plants and animals.
The answer should be 3, M.
For M, it is indicating to the organ gallbladder. The purpose of it is to store bile, which bile help physical digest fats. However, gallbladder is not the site that produces bile, that should be the liver.
Therefore, after bile is produced in the liver, they're stored in gallbladder. It then will be released through the bile duct to the site it is used for, which is the duodenum.
In meiosis I, the arrangement of any homologous chromosome along the center plane ( forgot the name for this) is independent of the arrangement of the other homologous chromosomes. There is thus equal probability for the chromosome to be in either of the two daughter cells after meiosis I. This is observed in meiosis 2 metaphase as well where the arrangement of each Sister chromatid about the ‘center plane’ is independent of each other. This independence observed during metaphase of meiosis I and meiosis II allows for chromatids to be in either gamete formed in equal probability, not affecting by other chromatids thus inheritance of one trait is not affected by the inheritance of another trait.
