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.

C. Ribosomes are too big to enter the nucleus.
D. DNA is too degenerate to use without mRNA.

Answers

Answer:

A

Explanation:

its not D or C and B might be true but its A okay

Why must an mRNA copy be made for Protein Synthesis because C. Ribosomes are too big to enter the nucleus

Why is mRNA important for protein synthesis?

mRNA is the molecule that includes the message contained within DNA to the ribosome. Ribosomes are where proteins are produced. mRNA is vital because ribosomes cannot attain the DNA inside our cell nucleus, which is the region within the mobile wherein DNA is housed.

Why is it important to make an mRNA reproduction of a DNA gene earlier than protein synthesis?

So as for cellular to fabricate these proteins, particular genes inside its DNA should first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into completely useful proteins.

Use your knowledge of inheritance (the passing of traits from parents to offspring) to explain why
these twins look so different even though they have the same parents. Why aren't they identical? In
your answer you should include your knowledge of gametes (sperm and egg), chromosomes, and
variation

Answers

Answer:

Fraternal twins can be different genders because they are two completely different eggs getting fertilized; but even two same gender fraternal twins do not look completely alike. Whereas for identical twins since one egg is splitting into two, the two cells have the same exact DNA make up and chromosomes.

I also believe the technical part of it is to do with genetics, like ressesive and dominant genes, because they can be the same gender, ex. both girls and one has blue eyes, fair skin, and blonde hair, the other twin has brown eyes, black hair and tan skin. The parents could be part of the genes but there is also grandparents maybe the mom's mom has blonde hair and blue eyes, with fair skin. But the dad he has brown eyes, black hair and tan skin. The moms genes were recessive, but the grandma's genes were dominant.

Which is held constant when a gas obeys Boyle's law?

C. temperature
D. volume

Answers

Answer:

B

Explanation:

ganyan rin sagot ko sa module ko

When a gas obeys Boyle's law, the temperature is held constant. The correct option is C.

What is Boyle's law?

Boyle's law is given by Charles Boyle. It is a gas law that states the pressure decrease with the increase in the volume and the temperature remain constant. In other words, the pressure exerted on gas is inversely proportional to the volume of the gas.

The law shows the relationship between pressure and volume, with the temperature remaining constant. There are three gas laws which are given by different scientists. These laws show the relationship between two variables and the third remains constant. These variables are temperature, volume, and pressure.

Thus, the correct option is C. temperature regarding the gas obeys Boyle's law, and it remains constant.

Answer;

An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove.

Explanation;

-Atoms are comprised of a nucleus consisting of protons (red) and neutrons (blue). The number of orbiting electrons is the same as the number of protons and is termed the "atomic number" of the element.
