Answer:Increase in ambient global temperatures.
Recyling energy to be used again
Regulation of oxygen and carbon dioxide levels
An increase of erosion and siltation along waterways
Explanation:
Conservational biologists think about the preservation of ecosystem by maintaining the environment in a human control way.
Increase in ambient global temperatures.: The humans must prevent the increase in global temperature worldwide by preventing the rise of greenhouse gases which can lead to global warming worldwide.
Recyling energy to be used again: The sources of energy like wood, waste water can be recycled again for reutilization.
Regulation of oxygen and carbon dioxide levels.: The oxygen and carbon dioxide levels must be regulated. As oxygen is the basic requirement for respiration. The increase in carbon dioxide levels due to human activities is likely to cause respiratory diseases and health hazards in living beings.
An increase of erosion and siltation along waterways.: The erosion and siltation will likely to deposit nutrients and debris which may either contaminate the waterway or may cause eutrophication.
<span>Interphase is the phase in the cell cycle during which cells that will undergo mitosis prepare for division. In interphase, DNA of the cell copies</span>. After that cell undergoes mitosis, which is the phase of the cell cycle during which cell divides on two identical. Mitosis consists of four phases:
1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up
2. Metaphase: Chromosomes line up at the centre of the cell.
3. Anaphase: The sister chromatids separate from each other to the opposite sides of the cells.
4. Telophase and Cytokinesis: Membrane forms around each set of chromosomes on two opposite sides of the cells and cell divides into two identical daughter cells.
<span>the value of a transitional fossil is : A. Transitional forms show the evolutionary steps between species
For example, take a look at human's transitional fossil.
Through the fossil, we became aware about the evolution that happened within the human species and we can observe how we developed from a monkey-like organisms into a more superior organism as we are today</span>
D. They come from other living things
Explanation:
The cell theory states that all living things come from preexisting cells.
<span><span>As for the responder, science study as much as it can
process. Though there are certain principles, theories and laws needed to
determine one is truly science. It needs to undergo the scientific method to
analyze and gather evidential data and in addition this study should be
replicable in the process. Replicable is one strong characteristic of a study
that can intensify the reliability and validity of the field. And what science
doesn’t study is not until the principles apply to the aforementioned
statement. Science can study and wants to understand everything or in as much
as the broader scope of each phenomenon, it’s some concepts that are just very
hard to gather data, and studies like the metaphysical and paranormal that can’t
be repeated. These limitations inhibit scientists to draw data that is reliable
and valid, thus, science. </span> </span>
