Fossils give evidence upon organisms the past are not the same as those found and demonstrate a progression of evolution.
The answer is A! <span>Deciduous forests are not affected by a wildfire or a prescribed fire.</span>
Answer:
The Golgi complex is compromised
Explanation:
The Golgi complex helps in the process of synthesis and packaging of proteins and lipids, especially those proteins that are for exportation. The organelle´s function is to manage the recently synthesized proteins, to transform them, and to export them to other places.
Different proteins are synthesized in the endoplasmic reticulum and sent to the Golgi complex in vesicles, where it happens the final association of carbohydrates with proteins. Finally, protein is transported from the Golgi complex to its final destiny. Proteins destined to a certain place are packaged all together in the same vesicle and sent to the target organ. In the case of membrane proteins, they are packaged in vesicles and sent to the cell membrane where they get incrusted.
By being affected by the achondrogenesis 1a, the Golgi complex loses its functions and is incapable of finishing the protein synthesis and transport process, affecting other cells and their functions.
The answer is stabilizing selection.
<span>Sickle-cell anemia is a recessive disorder caused by the presence of two recessive alleles "s", so genotype is "ss". This disorder is characterized by sickle hemoglobin. In an area with malaria, heterozygous individuals "Ss" (with one dominant allele and one recessive allele) have an advantage. These individuals will have both normal and sickle hemoglobin. But pathogen that causes malaria affect only normal hemoglobin, so heterozygous individuals will have half of the hemoglobin resistant to the pathogen and those individuals are resistant to malaria.</span>
Stabilizing selection favors heterozygotes Ss, disruptive selection favors dominant (SS) and recessive (ss) homozygotes, while directional selection favors dominant (SS) or recessive (ss) homozygote. Since in this example, people with genotype Ss (heterozygotes) are in advantage, then this is an example of stabilizing selection.
The amount of water on the planet is fixed; it neither increases or decreases. Glaciers are sheets of moving ice. This water to form these extensive sheets must come from somewhere. The water comes from the most extensive store on the planet; the oceans. Ice Ages always corresponds to periods of low sea level because much of the ocean water is is land locked as glaciers.
