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.

Explanation:

I hope this is right

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:

1) I identified the Golden-Brown Algae.

2)  It was very easy to find the category because of the solid color base and because it only had the daitoms. It did not have multiple like the Green Algae and the Blue-Green Algae.

3) In fresh, brackish or salt water. They are found both in tropical lakes and seas, and in the alpine and polar snows. They are unicellular or multicellular protist plant organisms, whose cells do not form tissues and lack flowers. They are considered the first link in the food chain in the aquatic environment. They are found in fresh, brackish or salt water. They are primary producers in the food chain, capable of producing organic substances through photosynthesis, so they use sunlight. They are found in tropical lakes and seas up to the alpine and polar snows.

4) Producer Alga is A plant and produces food for other organisms.

5) Algae (Euglena) do photosynthesis as plants do. They also move around and eat, as do animals. But they are unicellular. In order to be classified as a plant or animal, an organism has to be multicellular, made of more than one cell. Since it is a unicellular organism with some plant and animal characteristics, it is called a protist. Plant cells have walls while algae does't have one, so it is a protozoan. Algae resemble the protozoa, so they are put into the Protist Kingdom.

Explanation:

I had the project.

Algae recreate a major part of the marine ecosystem because they exist as the decomposers current in the marine ecosystem; any harm to them could cause an inequality in the whole marine ecosystem.

1)The Chrysophyceae, usually named chrysophytes, cryptomonads, golden-brown algae or golden algae exist as an extensive set of algae, seen mainly in freshwater.

2) It stood very easy to see the class because of the solid color base and because it only contained the diatoms. It did not contain multiple like the Green Algae and the Blue-Green Algae.

3) In fresh, saline, or salt water. They exist seen both in tropical lakes and seas and in the alpine and polar snows. They exist as unicellular or multicellular protist plant organisms, whose cells do not constitute tissues and absent flowers. They exist thought the first link in the food chain in the aquatic environment. They exist seen in fresh, brackish, or salt water. They exist as primary producers in the food chain, qualified of producing organic substances through photosynthesis, so they utilize sunlight.

4) Producer Alga exists in a plant and makes food for different organisms.

5) Algae (Euglena) accomplish photosynthesis as plants do. They even move about and eat, as do animals. But they exist unicellular. To be categorized as a plant or animal, an organism contains to be multicellular, made of better than one cell. Since it stands as a unicellular organism with some plant and animal elements, it exists named a protist. Plant cells contain walls while algae don't contain one, so it exists as a protozoan. Algae reach the protozoa, so they stand to put into the Protist Kingdom.

Answer:

They both had a tail as an embryo.

Explanation:

Both human and dogs have tail as an embryo. Temporary tail-like structures are present in the human embryo. These tail like structure develop around the fifth or sixth week of gestation, having about 10 to 12 vertebrae and removed when it reached to its full development stage while on the other hand, tail present in dog's embryo also developed with time and we can see when the dog baby is fully formed.

Answer:

They both had a tail as an embryo.

Their arm and leg structure is similar but may have a different function.

Explanation:

Vestigial structures are those body parts that have lost or reduced their original function during the evolution of a species. These vestigial structures might be found in many animals, including human beings. Vestigial structures were plenty functional for common ancestors. But with evolution, they degenerated, stunted, and became rudimentary for some of the new species.  

During the first 4 months of embryogenesis, all mammals have a tail at some point in their development. Dogs develop this structure and keep it during their whole lives, but humans lose it with time during embryogenesis. The tail disappears, and its forming vertebras get fussed with each other composing the coccyx, which represents a vestigial structure. This tailbone is the remnant of a missing tail.

In many animals, the function of the tail is to stabilize, equilibrate and mobilize. But in humans, the coccyx, located at the end of the vertebral column, has lost this original function.

The fact that whales, humans, and dogs all have the same bones in the same order, but they matured differently in later embryological development, is an example of homologous characters.  

Homologous characters have the same fundamental structures. They also share the same relations with adjacent structures, and they have the same embryological development.  

These structures might show variations between organisms exhibiting them, according to their function and to the environment in which the organism lives.  

These homologous characters are common in organisms related and that share a common ancestor.
