1. Would you consider a Zonkey (baby created from a donkey raised with a zebra) alive? Keep in mind that a Zonkey is sterile and cannot produce its own offspring.
2. Would you consider a virus alive? It requires a host completely to live.
Answers
Answer to 1:Yes the Zonkey is alive,not all organisms can reproduce. Some people are born with rare genetics were they can't give birth,so even if the Zonkey is sterile and can't produces it own offspring it is alive.
Answer to 2:Yes a virus is alive,it attacks the host and contains/kill other cells in your body. They also can multiple. If they can multiply and even attack and kill other cells they are alive.

A scientist is treating rice plants with a chemical that causes mutations. What is the possible benefit of this treatment? A. clones B. transgenic plants C. increased genetic variation D. increased hybridization
Answers
Answer:
Explanation:
Its either B or C, look closely at the question and at the answers, you can narrow it down from then.
A scientist is treating rice plants with a chemical that causes mutations. The possible benefit of this treatment is transgenic plants. Hence, the correct option is B.
What is mutation?A mutation is a change in the DNA sequence that makes up a gene. It can result from errors in DNA replication or exposure to mutagenic agents such as chemicals or radiation, or from spontaneous changes.
Transgenic plants are the plants that have been genetically modified to express specific traits or traits that are not found in the original species. This is done by introducing foreign DNA or chemicals that change the plant's genome. This process is called genetic engineering.
Transgenic plants have become an important tool in agriculture and biotechnology, providing new opportunities for food production, environmental protection and economic growth. Hence, the correct option is B.

Who is to blame climate change?
Scientists have measured global temperatures for over a hundred years and see that the Earth is getting hotter. Ice core data suggests the Earth should actually be cooling if it were following its natural cycles. The trend can be best visualized by comparing each year’s average temperature with the long- term average. Figure 1 shows observations of the world’s annual average temperature made by the National Oceanic and Atmospheric Administration (NOAA). In recent decades, the years have always been hotter.
Over geologic time, the Earth’s average temperature has changed as a result of the sun’s output, the tilt and position of the Earth in its orbit, and the concentration of greenhouse gases. Scientists have developed a good understanding of the natural variations in these factors by examining different data sources in order to estimate ancient temperatures. Observations tell us that these natural factors have not been changing over the last hundred years or so in a way that would explain the observed temperature increases.
In contrast, greenhouse gases have been changing in a way that can explain the observed temperature increases. Figure 2 shows the change in atmospheric CO2 concentration over the last thousand years. At the Scripps Institute of Oceanography in Hawaii researchers have been sampling pristine mountaintop air every month since 1958. Their observations show that both the concentration and isotopic composition of CO2 is changing, and is consistent with manmade sources, including the carbon emissions from burning fossil fuels. The industrial revolution marked a drastic increase in CO2 concentrations in the atmosphere when humans began using fossil fuels on a large scale.
Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. CO2 along with other gases are known as greenhouse gases. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric CO2. In its Fifth Assessment Report, the Intergovernmental Panel on Climate Change, a group of 1,300 independent scientific experts from countries all over the world under the auspices of the United Nations, concluded there's a more than 95 percent probability that human activities over the past 50 years have warmed our planet.

durring puberty
Explanation:
Answer:
Oxygen
Explanation:
"Photosynthesis" is a process that is being used by plants in order to sustain their metabolic needs. In order to do this, it converts "light energy" into "chemical energy." There are mainly three things that are needed for the process: sunlight, water and carbon dioxide.
Sunlight (provides light energy) comes from the sun while water is drawn from the plant's roots. The light energy fuels the process. Carbon dioxide, on the other hand, is taken from the air by the plant's leaves. Once these three things are combined, they produce sugar ([tex]C_{6} H_{12} O_{6}[/tex]) and oxygen (6[tex]O_{2}[/tex]). So, the other molecule being asked above is "Oxygen."
