<span>Location of the estuary, the amount & quality of fresh water flowing in and oceanic storms that have the tendency to push in more salt water are all huge causes of the amount of salt in the water of an estuary to change. </span>
Answer:
A. the heterozygote advantage
Explanation:
Heterozygote advantage is the condition where the heterozygous individual has higher relative fitness than both homozygous dominant and homozygous recessive individual. This means that the heterozygote individual has higher chances of surviving than both the homozygous counterparts. Sickle cell anemia is a recessive inherited disorder in which oxygen carrying hemoglobin has an abnormal structure. Hence, the resultant RBCs are not spherical but have crescent sickle shape. The oxygen carrying capacity of such RBCs is drastically reduced but they are unaffected by malarial parasite due to their abnormal structure.
- A person with both the recessive genes for sickle cell would not be able to survive due to insufficient oxygen transport in body.
- A person with both the dominant genes would be free of sickle cell anemia but in case of malaria would not be able to survive as the normal RBCs would be hijacked by the parasite.
- A hetrerozygote would survive both in malaria and sickle cell condition since he has enough normal RBCs for oxygen transport but also has sickle cell RBCs which are unaffected by malarial parasite.
Scientists use buoys to measure ocean conditions in specific locations over time. There are a variety of different buoys deployed in the ocean; some are attached to the ocean floor, while others drift freely in open waters. All ocean buoys, regardless of type, report some physical characteristic of the ocean or the atmosphere for later analysis.
In this virtual lab activity, you will use buoys to track a bottle as it travels on ocean currents worldwide. Problem: How can data from buoys be used to analyze ocean currents? Hypothesis: Predict the location each bottle came from using the tracking data in the Data and Observations section and the world map of major ocean currents pictured below.
For example:I predict bottle 1 is from ________canada _________, bottle 2 is from _____brazil_______,and bottle 3 is from ______carriboean islands________ based on the tracking data andworld map of currents
