The hypoxic zone in the Gulf of Mexico is not unique; at least 200 dead zones exist at estuaries and along seacoasts worldwide. These low-oxygen regions share many of the same causes, and they all have ecological and economic repercussions for ecosystems and people. Fortunately, we can pursue strategies to lessen the number, severity, and impacts of dead zones. The following list includes examples of factors that contribute to the development of dead zones (the cause), the consequences that result from dead zones, and possible solutions. Which of the following are consequences of dead zones?

a. Economic losses for fisher's
b. Death or aquatic organism that cannot escape
c. Policies to promote no-till agriculture
d. Construction of wetlands to absorb nutrients
e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition

Answer:

Answer:

e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition

Answer:

 Explanation:

Run off from agricultural wastes which contain Nitrogen and Phosphorus are the major sources  causes dead zones.The process where these chemical get washed into the aquatic bodies is called Eutrophication.

These substances leads to algae boosts in the water.The increases population of the algae consumes the available oxygen in the water, therefore making the oxygen concentration drops or no oxygen at all;(Hypoxia)

As the algae population feed on the available resources in the water they exhausted this,and later die.

When the decomposing bacteria used the oxygen in the water to breakdown the dead algae they make use of the available oxygen.This further reduced the oxygen availability and therefore   reduces the oxygen and hence the zone becomes the dead zone, because little or no oxygen is available  for survival of organisms.

This is reversible if the process if europhication or other causes  is eliminated

Various cultures designate racial categories differently, and they often base these categories on very different traits. For example, some cultures use nose shape as one of the defining traits for a racial group. Other cultures do not use nose shape in defining racial groups, but use hair color instead. Conduct a survey in person on your campus, via social media accounts online, or among your friends and family. Ask at least 20 people what five traits they think are most important when distinguishing racial groups. Document the responses, and then review the data. Did every person use the same traits? What do differences in racial classification such as these suggest about the universality of race and racial groupings?

Jayden is taking a test. He has to write why scientists support the theory that life began near hydrothermal vents in the ocean. Which point should he include in his answer?
A.
Hydrothermal vents were closest to ocean surface, and therefore could receive oxygen.
B.
Oceans were dry and only had water near the hydrothermal vents in the earlier ages.
C.
Even today, all life forms are first born near hydrothermal vents and they later migrate to land.
D.
Fossils of archeabacteria, which are early common ancestors, were found near hydrothermal vents.

A certain species of lizard comes in three colors: cream, golden, and brown. All lizards are a single solid color (ie, none ever have spots or stripes) You carry out matings between these lizards, and collect the following data:

• Cream and brown lizards can be true-breeding, but golden lizards never breed true.
• Matings between cream and golden lizards always yield cream and golden offspring in a 1:1 ratio.
• Matings between brown and golden lizards always yields brown and golden offspring in a 1:1 ratio.
• Mating golden lizards with other golden lizards always yields brown lizards, golden lizards, and cream lizards in a ratio of 1:2:1, respectively.

Required:
Assign allele symbols to all alleles of the lizard color gene, and indicate which genotypes result in which phenotypes.
