7 DDT is a pesticide that was once widely used to control agricultural pests and
mosquitoes. However, this pesticide caused the eggshells of certain birds, including the
brown pelican, to become fragile and thin. The adults would then accidentally crush the
eggs while trying to incubate them.
What happened to brown pecan populations as a result of DDT use by humans?
A The populations increased much more slowly.
B The populations decreased as fewer eggs survived long enough to hatch.
C The populations remained stable over time.
D The populations increased as pelicans laid more eggs so that more offspring would
survive.
Answer:
The answer is B. The populations decreased as fewer eggs survived long enough to hatch.

7. What is the correct order of the levels of organization in the human body from
the simplest to the most complex?
Answer:
The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism.
All living and non-living things are made of one or more unique substances called elements, the smallest unit of which is the atom, (for example, the element oxygen (O) is made of O atoms, carbon (C) is made of C atoms and hydrogen (H) is made of H atoms. Atoms combine to form molecules.
All living structures are made of cells, which are made of many different molecules. Cells are the smallest independent living thing in the human body. The body is made of many different cell types, each with a particular function, (for example muscle cells contract to move something, and red blood cells carry oxygen). All human cells are made of a cell membrane (thin outer layer) that encloses a jelly-like cellular fluid containing tiny organ-like structures called organelles.
A tissue is a group of similar cells that work together to perform a specific function. There are four main tissue types in humans (muscular, epithelial, nervous and connective). An organ is an identifiable structure of the body composed of two or more tissues types (for example, the stomach contains muscular tissue made of muscle cells, which allows it to change its shape, epithelial tissue which lines both the inner and outer surface of the
stomach, nervous tissue which sends and receives signals to and from the stomach and the central nervous system, and connective tissue which binds everything together).
Organs often perform a specific physiological function (for example, the stomach helps digest food). An organ system is a group of organs that work together to perform a specific function (for example, the stomach, small and large intestines are all organs of the digestive system, that work together to digest foodstuff, move nutrients into the blood and get rid of waste). The most complex level of organization, the human organism is composed of many organ systems that work together to perform the functions of an independent individual.

What effects do wind patterns have on climate?
They move warm water toward the east.
They change the amount of precipitation in a region.
They carry warm or cooled water very long distances.
They cool Pacific waters and increase hurricane activity in the western Atlantic.
Answer:
b
Explanation:

Winds can model the climatic patterns by moving air at different temperatures and with varying humidity levels. The correct option is B. They change the amount of precipitation in a region.
What is the influence of winds on climate?The term convective cell refers to air getting warm, expanding, and ascending. As it gets to higher altitudes, it gets colder and thicker, and hence descends again.
Unequal warming of the atmosphere results in convective atmospheric circulation cells: Hardley cell, Ferrel cell, and Polar cell.
In each hemisphere,
Warm air ascends at the equator and approximately at 60º latitude. Cold air descends at approximately 30º latitude and at the poles.These air masses circulation generates superficial winds that blow toward the equator between 0º-30º latitude and toward the poles between 30º-60º latitude.
As winds move, they carry air at different temperatures and moisture from one place to another, producing different precipitation patterns. This affects the climatic conditions in different geographical zones.
Winds movement, interaction, and encounters model the climatic patterns at a global level.
The correct option is B. They change the amount of precipitation in a region.

Which of these energy resources is sustainable? A. Wind O B. Oil O C. Coal O D. Biofuel
Answer:
A. Wind.
Explanation:
Energy resources which are sustainable are the ones which would never run out. Wind is something that won't run out because of the windmills in several countries used to generate electricity. Oil, coal and biofuel are limited resources and isn't sustainable at all.
The energy resource that is sustainable from the given options is A) Wind. It is used in various ways of the energy production as well.
Biofuels can be sustainable, but it depends on how they are produced. Biofuels made from sustainable sources such as waste materials or non-food crops are considered sustainable.
However, biofuels made from food crops can contribute to deforestation, food shortages, and other environmental and social issues.Overall, Wind energy is the most sustainable option from the given choices as it is renewable and environmentally friendly.

Does the carbon cycle in this diagram appear to be in balance or out of balance? Use specific evidence from the diagram to support your answer. This diagram shows gigatons of carbon moving to and from the atmosphere each year.
This diagram shows gigatons of carbon moving to and from the atmosphere each year and yes the diagram is valences.
Which factor is responsible for fixation?Cutting down large areas of forests Plants are responsible for fixation of atmospheric carbon dioxide. If the number of plants is reduced, the amount of carbon dioxide moved from the atmosphere to vegetation will also decrease.
The biogeochemical cycle in which carbon is exchanged between the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth is known as the carbon cycle.
According to the question, emitted amount of carbon is 480 gigatons but the amount of carbon in the environment is approx 190 gigatons, so the remaining amount of the carbon was stoored by the oceans and other water reservoir, which may be get clear throug the attached diagram.

In 1906, President Theodore Roosevelt created the Grand Canyon National Game Preserve on the Kaibab Plateau in northern Arizona. Between 1907 and 1923, cattle grazing was greatly reduced, mule deer hunting was eliminated, and predators were killed. Over 800 cougars, 20 wolves (most had already been killed in the 1800s), and 7000 coyotes were trapped or shot. In response, the mule deer herd began to increase: By 1915, deer numbers were estimated at 25,000; 50,000 by 1920; and 100,000 by 1923. The removal of the livestock and predators, and the cessation of hunting in 1907 ________. decreased the carrying capacity for the Kaibab deer decreased r, allowing more births among Kaibab deer decreased K, allowing more births among Kaibab deer removed the limits on immigration, allowing more deer into the area increased the carrying capacity for the Kaibab deer
Answer: increased the carrying capacity for the Kaibab deer
Explanation: The removal of livestock means more food as grass is available for the Kaibab deer to feed on. In the same vein, the nonexistence of predators would allow for proliferated growth which in turn would increase the number of deer population on the plateau. What this means is that the Preserve is now able to carry as much deer population as it could going forward thereby increasing the carrying capacity for the Kaibab deer which was evident by the increasing figures on the years the deer numbers were estimated.
