A researcher was interested in tracking the number of birds that became totally coated with oil and needed to be rescued during the bp oil spill in the gulf of mexico in her research area. Everyday she would go out in her boat and rescue the birds that were coated. At the end of each day, she recorded the total number of birds that she rescued. What type of graph would she use to get an estimate of center and spread?.
Answers
To get an estimate of the center and spread of the number of birds rescued each day, the researcher could use a statistical graph known as a histogram.
A histogram is a graphical representation of data that is divided into intervals or bins along the x-axis, with the frequency or count of observations for each interval plotted on the y-axis. In this case, the x-axis could represent the number of birds rescued, and the y-axis could represent the frequency or count of each number. By creating a histogram, the researcher can visually observe the distribution of the number of birds rescued. The shape of the histogram can provide information about the center of the data (such as the most common number of birds rescued) and the spread (such as the range or variability of the number of birds rescued).The researcher can analyze the histogram to determine measures of center, such as the mean or median, which can provide an estimate of the typical number of birds rescued. Additionally, measures of spread, such as the range or standard deviation, can indicate the variability or dispersion of the data. Using a histogram allows the researcher to visualize and analyze the distribution of the number of birds rescued, helping to estimate the center and spread of the data.

What do biological anthropologists call the taxonomic group that includes humans and humanlike ancestors, excluding living nonhuman primates?
Answers
Biological anthropologists call the taxonomic group that includes humans and humanlike ancestors, excluding living nonhuman primates as hominins.
In the field of anthropology, hominins can be described as the taxonomic group consisting of modern humans, ancestral humans, and extinct species of humans.
Primates that do not have human-like origin are not a part of the hominins. Humans are the current living species of hominin origin. The ancestors through which humans came into existence are studied through fossils and are extinct hominins.
Biological anthropologists differentiate hominins from other primates based on their special characteristics such as straight posture, having specific language speaking ability, walking on two legs etc.

Can light cause the rubber to become solid? Why or why not? Does it matter what type of light she shines on the rubber?
HELP PLEASE
Answers
Sierra's special kind of liquid rubber has some unique properties when it comes to the interaction of different types of light with it. It is known that ultraviolet light gets absorbed by the rubber, X-ray light can pass through it, and blue light is reflected off of it.
Sierra's curiosity leads her to wonder if the liquid rubber will become solid if she shines various types of light on it. However, the answer to this question is not straightforward. The process of solidification for rubber involves chemical reactions, and the interaction of light with the material is not directly related to its solidification. Therefore, shining different types of light on the liquid rubber may not necessarily cause it to solidify.
That being said, it is possible that the exposure of the liquid rubber to various types of light could alter its chemical composition or structure, which could then lead to its solidification. However, this would require further investigation and experimentation.
In conclusion, the interaction of different types of light with Sierra's special liquid rubber may not have a direct impact on its solidification. Further research and experimentation would be necessary to explore the effects of light on the chemical structure of the rubber and its solidification process.

Starting with fructose 6-phosphate and proceeding to pyruvate, what is the net yield of atp molecules?
Answers
Net yield of ATP starting with Glucose-6-phosphate is 3 ATP molecules.
The steps to the solution are as follows :
Step 1.
Fructose-6-phosphate is formed from glucose-6-phosphate.
Step 2.
Fructose-6-phosphate is converted to fructose-1,6-bisphosphate. One ATP molecule is used in this step.
Step 3.
Fructose 1, 6-biphosphate is converted into one molecule of each of three carbon compounds: dihydroxyacetone 3-phosphate, glyceraldehyde 3-phosphate, and glyceraldehyde 3-phosphate.
Step 4.
2 glyceraldehyde 3-phospahte molecules are converted into 2 glyceraldehyde 3-biphosphoglycerate molecules.
Step 5.
One molecule of 1, 3-biphosphoglycerate is converted into three molecules of 3-phosphoglycerate, yielding two molecules of 3-phosphoglycetare. This step required two ATP molecules, one for each molecule of 1, 3-biphophoglycerate converted.
Step 6.
Each molecule of 3-phosphoglycetare is converted to 2-phosphoglycetare, resulting in the formation of two molecules of 2-phosphoglycerate.
Step 7.
Each 2-phosphoglycerate molecule is converted into phosphoenol pyruvate.
Step 8.
Each phosphoenol pyruvate molecule is converted into pyruvate by producing one ATP molecule. As a result, two pyruvate molecules are formed, as well as two ATP molecules.
As a result, the net yield of ATP from glucose-6-phosphate to pyruvate is;
The number of ATP molecules used = 1 (during the step of converting fructose 6-phosphate to fructose 1, 6-biphosphate.
No. of ATP molecules formed = 4 (2 ATP molecules formed during the step of converting 1, 3-biphophoglycerate to 3-phosphoglycerate and 2 ATP molecules formed during the step of converting phosphoenol pyruvate to pyruvate).
As a result, the net yield of ATP is equal to 3.

A company is growing algae in big tanks to make fish food. However, the algae is not growing very quickly, and they suspect either phosphorus, nitrogen, or iron is limiting. What could the company do to figure out which nutrient is limiting?a)Add phosphorus to one tank, nitrogen to another, and iron to a third, and see which treatment increases algal growth.b)Add phosphorus, iron, and nitrogen to all tanks, and see which nutrient increases algal growth.c)Add phosphorus to all tanks, because phosphorus is the nutrient that limits algal growth.d)Add nitrogen to all tanks, because nitrogen is the nutrient that limits algal growth.
Answers
Experiment
In this experiment, as the question the investigators are trying to answer is what component is the limiting one, it is necessary to test every one of them, independently. Therefore, the best option is to change the concentration of one of them and leave the rest unchanged. To accomplish this, would be necessary three different tanks, one for phosphorus, one for iron, and one for nitrogen (option A).
To determine which nutrient is limiting algal growth, the company can add phosphorus to one tank, nitrogen to another, and iron to a third, and see which treatment increases algal growth. Therefore, option A is correct.
By adding each nutrient separately to different tanks and observing the effects on algal growth, the company can identify which nutrient is limiting. If the addition of phosphorus to one tank leads to increased algal growth, it suggests that phosphorus was the limiting nutrient.
Similarly, if the addition of nitrogen or iron to their respective tanks results in increased algal growth, it indicates that nitrogen or iron, respectively, was the limiting nutrient. Thus, option A is correct.

Answers
Land plants no longer required water as a medium for reproduction with the evolution of seeds and pollen. Seeds and pollen are specialized structures that allow plants to reproduce without the need for water.
This development has allowed plants to colonize a variety of habitats on land, including arid environments, where water is scarce. Land plants evolved from aquatic ancestors, and the earliest land plants likely required water for reproduction. However, as plants adapted to life on land, they developed structures that allowed them to reproduce without water. Fruits and roots are important structures for land plants, but they are not directly involved in reproduction.
Flowers and leaves are also important for land plants, but they evolved after seeds and pollen and are not required for reproduction in all plant species. Cell walls and rhizoids are important adaptations for land plants, but they are not directly related to reproduction. Lignified stems are important for structural support in land plants, but they are not directly involved in reproduction.
Therefore, the correct answer is 5 seeds and pollen.
