Answer:
Some possible solutions include:
1- to replace oil and gas energies with renewable sources
2- to replace fossil fuel-based transport systems with sustainable methods
3- to recycle material
4- to prevent air pollution
Explanation:
The replacement of fossil fuel energy sources with renewables energy sources (e.g., solar energy, wind energy, geothermal energy) can be considered the most important strategy to reduce (and even revert) the human effects on climate change. Moreover, sustainable transportation systems or 'green transport methods' (e.g., walking, cycling) don't consume fossil fuels, and therefore they have zero impact on the environment. Recycling materials can also be very useful in order to reduce greenhouse gases (e.g., CO2) by reducing the consumption of energy. Finally, methods to prevent air pollution (for example, by avoiding the burning of leaves and trash) can be applied in order to reduce CO2 emissions and thus minimize environmental impact.
Cells can be classified into two different categories: prokaryotic and
eukaryotic. Which of the following information is needed in order to
determine if an organism is prokaryotic?
Answer:
Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide.

How is DNA created?(short answer)
Explanation:
For a strand of DNA to form, nucleotides must be linked into chains, with the sugar phosphate groups alternating. DNA is made of the building block chemical called nucleotides. Nucleotides are made up of three main parts, a sugar group, a phosphate group, and some type of nitrogen base. Hope this answers, and is helpful! Have a great day! :))

What are the environmental issues with using coal as a source of energy?
How do plants and humans help each other out?
Answer:
Photosynthesis and respiration are the two essential processes that allow life to sustain on earth. In a way, they are a cycle — plants help humans breathe by providing us with oxygen, and humans help plants "breathe" by providing them with carbon dioxide.

A scientist is examining layers of the
earth and tracking information about
animal fossils found in each layer. For
many of the deeper layers there are
consistently large animal skulls but
there is a sudden shift in the skull size in
one layer and they are all much smaller
at that point for the remaining layers
until the earth's surface. What does this
suggest?
This suggests that sudden change that occur to the environment cause a different size animal to become the main species of that area.
Why the fossils of small skull organisms were found?This is because at that particular environment the small skull organisms can survive at that time as compared to big skull animals. The presence of a specific type of fossil in the soil layer shows that the fossil organism live at that time on this area due to the presence of good environmental conditions so we can conclude that environment was good for the small skull organisms at that time.

Answer:
the total resistance is 12 ohms
Amps = 1 amp
Explanation:
resistor in series add so the total resistance is 12 ohms
E=I x R E = voltage, I = amps, R = resistance
12 = I x 12
I=1
1 amp
resistor in series add so the total resistance is 12 ohms
E=I x R E = voltage, I = amps, R = resistance
12 = I x 12
I=1 is the correct answer

Brainly will be given
Answer:
[tex]\boxed {\boxed {\sf d=0.5 \ g/cm^3}}[/tex]
Explanation:
Density is equal to mass over volume.
[tex]d=\frac{m}{v}[/tex]
The mass of the wood is 6.0 grams and the volume is 12.0 cubic centimeters.
[tex]m= 6.0 \ g \\v= 12.0 \ cm^3[/tex]
Substitute the values into the formula.
[tex]d=\frac {6.0 \ g}{12.0 \ cm^3}[/tex]
Divide.
[tex]d=0.5 \ g/cm^3[/tex]
The density of the wood is 0.5 grams per cubic centimeter.
How important is it for a cell to maintain the same number of chromosomes? Explain.
Answer:
It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set. Before mitosis, the chromosomes are copied.

Explain why it is necessary that gametes (egg cells and sperm cells) have half the DNA that normal body cells have.
Answer:Gametes are reproductive cells, such as sperm and egg. As gametes are produced, the number of chromosomes must be reduced by half. Why? The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.
Explanation:
1. According to Model 1, in what type of organs are the cells that enter meiosis I found? 2. Considering what you already know about mitosis in cells, what event must take place during interphase before a cell proceeds to division? 3. What two structures make up a single replicated chromosome? 4. In Model 1, how many replicated chromosomes does the cell contain during prophase? 5. At which stage in meiosis I do the pairs of homologous chromosomes come together? 6. Once the chromosomes have formed a pair, what are they called?
Answer:
1.) Sex organs
2.) DNA replication
3.) Sister chromatids
4.) Two identical daughter cells
5.) Late prophase 1
6.) Tetrads
Explanation:
Meiosis is a type of cell division that occurs in living organisms which involves the division of a single cell to produce four cells containing half the original amount of the parent genetic information. An example of organs that enter meiosis is the SEX CELLS.
Mitosis is another type of cell division that leads to the production of two daughter cells which are genetically identical to the parent cell. During interphase before a cell proceeds to division, DNA replication must occur. This is a process DNA uses to make a copy of itself during cell division.
Chromosomes are genetic material which occurs in pairs known as the SISTER CHROMATIDS
PROPHASE in the stage the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells
During late prophase 1 the pairs of homologous chromosomes come together to form two chromosomes and four chromatids, with one chromosome originating from each parent.
Once the chromosomes have formed a pair they are called TETRADS

thrombocytes are essential for coagulation of blood comment
Answer:
Thrombocytes. Thrombocytes (platelets) play an important role in hemostasis, by plugging and repairing damaged blood vessels, thus preventing blood loss. They also participate in a cascade of events that leads to blood clotting by triggering the release of a series of coagulation factors
Answer:
Blood is a connective tissue.it has many cellular components.Thromobocytes or platelets are one of theme.<br> Thrombocytes of platelets are found in blood .There number in the blood is 250000 /cubic mL of blood .They are formed in bone marrow and their life span is one week <br> When an injuiry is caused in the blood vessele,bleeding starts ,and the platelets are disingrated to release the clotting factor 3 called thromboplastin .This in presence of
Ca2+
ions activats prothrombokinase.A series of reaction ultimately occurs which causes blood to clot and plugg the injured blood vessel thus preventing further loss of blood
