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.
Give evidence and reasoning!!

Answer:

1. Because the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.

2. Summary: Changes in the size and form of the beak have enabled different species to utilize different food resources such as insects, seeds, nectar from cactus flowers as well as blood from iguanas, all driven by Darwinian selection

3.  Medium ground finches with larger beaks could take advantage of alternate food

4. three species of Darwin's tree finches have been known to inhabit Floreana  but no birds singing that song on Floreana have been heard in many years.

Answer:

In eukaryotic cells, or cells with a nucleus may this help u buddy

Answer:

The shelves or die and will not be able to produce sugars. Blocking electron flow prevents the formation of the proton gradient required to produce the ATP used for sugar production.

The shrubs will die because they cannot photosynthesize. Without it, plants begin to wilt and finally die because photosynthesis requires light.

In essence, photosynthesis is the mechanism that powers the survival and growth of plants and even algae. The majority of plants would perish quickly if photosynthesis suddenly stopped.

Night-time is not a time when plants engage in photosynthesis. Only when exposed to the right wavelengths of artificial light during the night can plants perform photosynthesis. Light energy is absorbed with the aid of the pigment chlorophyll. Light energy is converted into chemical energy through the process of photosynthesis.

Your answer is Small Intestine.

Your small intestine makes digestive juice, which mixes with bile and pancreatic juice to complete the breakdown of proteins, carbohydrates, and fats. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. Your small intestine moves water from your bloodstream into your GI tract to help break down food. Your small intestine also absorbs water with other nutrients.

Answer: Small intestine

Either you put small intestine in the wrong place, or you're able to put the same one for multiple questions

Answer:

Due to its high intelligence.

Explanation:

Scientists think that cuttlefish  have the biggest brain to body ratio of all  invertebrates that allows it to sense sight, smell, and sound that comes to it in the form of pressure waves. Due to this big brain, cuttlefish are very intelligent so due to its intelligence the scientists thinks that cuttlefish has the biggest brain as compared to other big vertebrates such as octopus.

Answer:

so in the punnet square, you hvae the 4 squares inside the big on. on top of the square, you have 2 letters, representing the dominant and the repressed genes. On one side, typically  the left, you have another two letters, again genes. to get the gene types to fill in your squares, you take the first letter of the top set and the first letter of the side set. for this example, we are going to use Bb(top) and BB(side). you would take the B from the top, and you would pu it with the B from the side. in the top left square, you should have BB. next, you go and take that same top B and do it with the second letter of the side, B again. this again gives you BB.  next, you take the second letter of the top, b, and you join it with B. in the top right square, you would write or type in Bb. Even though the b was on top, it is after the B because in this cause, it is not the dominant gene. when you do the second top and side letters together, you again get Bb.

Answer:

A type of allele that when present on its own will not affect the individual. Two copies of the allele need to be present for the phenotype to be expressed.

Explanation:

Answer:

A recessive allele is a variety of genetic code that does not create a phenotype if a dominant allele is present. An allele is a specific variation of a gene, or specific segment of DNA. Different alleles produce slightly different proteins, which function in different ways.
