Answer: All of the above


Long term drought, change of season from winter to summer, forest fire are unfavorable environmental factors which can deplete the amount of resources already available with the ecosystem.

The long term drought will be a condition in which the ecosystem will suffer from non-availability of water.

The change of season from winter to summer can affect the organisms which are adapted to survive in the winters therefore, the biodiversity resources will be affected.

A forest fire is likely to be spread over the large number of tree populations which could be the habitat for large number of insects, animals and birds species hence, here also the biodiversity will be affected result in the loss of biodiversity resources.

Consider this northern site of primary succession following the retreat of a glacier. As we move from left to right, describe some improvements in the abiotic factors that support plant growth. A) change in climate over time B) less competition for water resources due to biodiversity C) improved soil quality: increased humus and water retention D) increased population density resulting in decreased pathogens

Answer: C. improved soil quality: increased humus and water retention.


An ecological succession brings change in the type of living species residing in an ecosystem with respect to changes that occur in the abiotic (non-living factors) with respect to time.

A region affected by a retreating glacier will not be suitable for the growth of living species. The soil may be lacking minerals and will be in the permafrost condition. So for the initiation of succession the improvement in soil an important abiotic factor is required. The improved soil quality will allow the accumulation of organic and inorganic minerals by physical and biological processes. This will help in formation of humus and water retention.

A: erosion, nutrient depletion, and desertification.

B, C, and D all contain drought which isn't a result of poor soil management, it's just not getting enough water.

Poor soil management, however, can cause erosion, nutrient depletion, and desertification.

You farm kelp and sell the kelp for food and as fertilizer. The wastes from the kelp can be used in an integrated aquaculture system in which kelp farming can be coupled with farming of fish or abalone. Make an argument that you are using a sustainable system of growing a renewable resource, and explain why it is beneficial (and more sustainable) to couple algae farming with fish farming than simply to farm fish independently.

A sustainable system refers to producing less or probably non-existent debris that are caused by the production of a particular material (i.e. produce, energy). This is a sustainable form of production of coupling algae growth and fish farming because you no longer need the supply of fish feed from other sources that are made artificially but rather, you are using the available algae growth that you are culturing. Farm fishing alone is non-renewable because this produces much waste that can directly harm the environment.

Pumping carbon dioxide directly into the deepest zones of the ocean has been proposed as a strategy to mitigate climate change. Do you feel this would be an effective method for protecting the environment? Explain your answer, including one pro and one con, and whether this would be a permanent solution.

Pro: Pumping carbon dioxide directly in to the deepest zones of the oceans can have a great deal in lessening the greenhouse gases that are produced within the Earth's atmosphere. 

Con: Some organisms are tolerant to such practice, but some experiments have yielded that some organisms are not and can die from such exposure to too much carbon dioxide mixing with other chemicals that are found underwater. 

Permanent Solution: Greenhouse gases can be minimized if there will be regulations regarding the production of goods in factories, mines, and agriculture. If these things are regulated, the release of such bad gases will be lessened and nothing underwater will be harmed.

HELP! 25 POINTS!!! A baby's first breath initiates a series of changes that includes which of the following? A. The ductus venosus and ductus arteriosus both open. B. The ductus venosus and ductus arteriosus both close. C. The ductus venosus opens, and the ductus arteriosus closes. D. The ductus venosus closes, and the ductus arteriosus opens. Please answer and explain!!!!

The most profound change at birth is your baby’s first breath. At this point, your baby’s lungs, which were filled with fluid during pregnancy, must suddenly fill with oxygen from the air. The fluid in the lungs is removed through the blood and lymph system, and is replaced by air. Your baby’s lungs must be able to exchange oxygen for carbon dioxide. At the same time, vigorous blood circulation in the lungs will begin. The first few breaths after birth may be the most difficult breaths your baby will take for the rest of her life.

There are a couple of things that will stimulate your baby to take her first breath. Hormonal and other changes during labour slow down or stop the production of fluid in the lungs, and may initiate the reabsorption of fluid from the lungs. This process is unlikely to have occurred if labour was very short or did not occur at all, for example, if your baby was delivered by caesarean section. Furthermore, physical stimulation and handling during delivery will encourage your baby to breathe. There are probably many other factors that stimulate baby’s first breath, but they have not been identified yet.

Your baby will need to work very hard to take her first breath, and her first few breaths may be shallow and irregular. With each breath after birth, more air will accumulate in her lungs, which will make it easier for her to breathe. After a few breaths, your baby will be able to breathe more easily, and her breaths will start to become deeper and more regular.

As the fluid in your baby’s lungs is replaced by air, the increased amounts of oxygen will stimulate a blood vessel close to her heart called the ductus arteriosus to begin closing. The ductus arteriosus was important to your baby’s body before birth, to divert blood away from the lungs. After birth, your baby needs blood to circulate through the lungs, and therefore, the ductus arteriosus is no longer needed. The ductus arteriosus usually closes during the first or second day of life. At this point, your baby’s heart will pump and circulate blood in much the same way as an adult’s heart. The transition from fetal to adult circulation can take minutes or hours. Problems with your baby’s colour or breathing may be related to this delayed transition.

Which process below would be considered a chemical change? A. Mixing two cheeses in a bowl. B. Grating cheese. C Molding of cheese.


The answer is C Molding of cheese.


A chemical change is a variation in the internal structure of a compound, to the point that it will be different from what it originally had. In a chemical change a change in the nature of the substance is verified, since new substances are produced totally different from the initial one, because there is a change in the chemical identity of the matter, where said the change is permanent. when the cheese is molded its chemical structure is permanently changed to what it used to be originally.
