What are some positive effects of a slow change to an ecosystem?

QUESTION POSTED AT 26/03/2020 - 10:20 PM

Answered by admin AT 26/03/2020 - 10:20 PM


An ecosystem is very likely to be changed due to various conditions such as a change in the temperature, rate of precipitation level, pressure in that area, the moisture content in the air, and the wind. These factors are responsible for the slow and rapid changes in the ecosystem.

The slow changes are sometimes helpful to the ecosystem. The increase in the amount of sunlight and rainfall provides nutrients to the soil, and helps in the growth of different plant species and maintains a favorable condition for the organisms to exist in an ecosystem.  

The slow rise in the temperature allows some of the species to adapt to that environmental condition and those that cannot adapt migrate to the regions of higher latitude for their survival.

Thus, the slow change in the ecosystem allows the organisms to adapt to that particular environment without losing their habitat and making it more suitable to live in it.

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 scientist wrote an article about a drug that he believes reduces the effects of viral infections. Which of these MOST LIKELY needs to be done by a scientific committee before the drug is made available to the general public? A) An experiment related to the drug but not about viral infections B) A review of the scientist’s credentials and a review of the article C) An experiment not related to the drug but about viral infections in general D) An experiment related to the drug and a review of the article written by the scientist


The answer is d)An experiment related to the drug and a review of the article written by the scientist


A scientific committee will verify that the medication has been evaluated in its entirety before placing it at the disposal of the general public, and for this it should be verified that said medication is supported through scientific experimentation, which will help establish the nature between independent variables and dependents. In a controlled study of a drug, scientists conduct two or more experiments simultaneously: a treatment group, where the effect of manipulation on a dependent variable is analyzed, and a control group, in which the same conditions are used, to treatment exception.

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.

Sickle-cell disease is a genetic disorder that causes many red blood cells to become sickle shaped. As shown in the diagram, sickle-shaped cells can clog blood vessels and impede blood flow. What does the effect of sickle-shaped cells on blood flow imply about the shape of normal red blood cells?


The answer is :

Blood viscosity increases and results in decreased blood flow throughout the body.


Blood flow is directly proportional to pressure and indirectly proportional to resistance.

Sickle-shaped blood cells tend to accumulate and increase the blood viscosity, which increases resistance. Therefore, blood viscosity increases and results in decreased blood flow throughout the body.

This answer is for STUDY ISLAND.

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.

The given graph shows the levels of the different hormones during the period of ovulation. During the phase of the ovulation, the hormones level increase. This increase in  the levels of the hormones prepare the uterus for the fertilization of the egg. The uterine line is thickened. This is the phase when the LH  (Luteinizing hormone) surge occurs, which refers to the sudden increase in the levels of LH. Moreover, the levels of FH, estradiol, and progesterone are also increased at different rates during ovulation.

Hence, the correct answer is 'option A - The hormone levels increase to prepare a woman's body to receive fertilized egg'.

Why is the term global warming often used when referring to climate change? Every location on earth is hotter every year than the year before. The sea temperatures have increased by 20 degrees. On average, the overall trend for the earth's surface temperature is increasing. None of the above are true.

The greenhouse effect occurs naturally, providing a habitable climate.Atmospheric concentrations of some of the gases that produce the greenhouse effect are increasing due to human activity and most of the world's climate scientists consider that this is a significant part of the cause of observed climate change.The oceans are a critical part of the climate system, with vastly greater thermal capacity than the atmosphere. Most of the net energy increase in the climate system in recent decades is stored in the oceans. A small, slow increase in their temperature is significant.Over one-third of human-induced greenhouse gas emissions come from the burning of fossil fuel to generate electricity. Nuclear power plants do not emit these gases.

The "greenhouse effect" is the term used to describe the retention of heat in the Earth's lower atmosphere (troposphere) due to concentrations of certain trace gases and water vapour in the atmosphere. These gases are generally known as greenhouse gases*. Concentrations of some of them have increased steadily during the 20th century and into the 21st, with CO2 rising from under 300 ppm to 400 ppm. A large part of the increase in all greenhouse gases is attributed to human sources, i.e. it is anthropogenic, hence the term ‘anthropogenic global warming’ (AGW).

Predict which of the following can impact an ecosystem's available resources? Long term drought Change of season from winter to summer A forest fire All of the above

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.
