explain global warming and climate change
Answer:
Global warming is the increase in the earths atmosphere from several things. Pollution is the main cause of this. "Global warming" is the overall effect and "climate change" is what is happening to our planet currently.The average global tempature is increasing at a very high rate and is getting worse very quickly. Scientists say that unless we slow down global-warming emissions, average U.S. temperatures could increase by up to 10 degrees Fahrenheit over the next century. Pollutants can last over a year in our atmosphere these pollutants trap the heat and cause our atmosphere to become warmer (green house effect). The biggest source of climate change is the burning of fossil fuel :coal, petroleum, natural gas, oil shales, bitumens, tar sands, and heavy oils.

A group of people have white blood cell (WBC) counts that are from 4,500 to 10,000 WBC/ml. All cell count values in that range are equally abundant in the population. What is the mean WBC count in the population?
Answer:
7250 WBC/ml
Explanation:
The mean of any value is the average of a certain amount of given values. When this is taken into cognizance, to get the mean White Blood Cell count of the population, given two ranges, is to add and divide both together. This gives us
10,000 + 4,500 = 14,500 WBC/ml
The mean then is
14,500 / 2 = 7250 WBC/ml
Therefore, the mean White Blood Cell count in the population is 7250 WBC/ml

Where are steroid receptors generally located and where do they bind the steroid hormone once it enters the cell:____________
A. They are located and bind the steroids in the middle of the cell membrane
B. They are located and bind the steroids in the cytoplasm
C. They are located and bind the steroids on the intracellular membrane surface
D. The receptors are located in the cytoplasm but they bind their ligands in the lysosomes.
Answer: B. They are located and bind the steroids in the cytoplasm
Explanation: Steroid hormones are a class of organic compounds, typically lipids. They bind to protein receptors in the cytoplasm or nucleus of the target cell and thus, their receptors are located inside target cells where they function as ligand-dependent transcription factors. This is to say that hormone-receptor complex formed on binding to DNA activates specific genes that increases production of proteins.
Rhonda visits her MD because she is feeling constantly tired. After a thorough case
history involving questions about her diet, her MD takes a blood sample. Results
indicate that her hemoglobin level is at 7g/100ml of blood (normal levels are 12-
18g/100ml of blood).
Based on the results of Rhonda's bloodwork:
a) What condition might Rhonda have ?
b) Why would Rhonda's low hemoglobin level cause her to feel tired ?
c) Rhonda's MD asked about iron intake (eg. from meat) in her diet? Explain why.
Answer:
a) Rhonda might have anemia
b) Rhonda feels tired because her blood is unable to transport enough oxygen
c) Iron is required by the blood cells for the formation of hemoglobin
Explanation:
a. A low hemoglobin level is referred to as anemia or low red blood count. From her blood test results, Rhonda has below normal levels of hemoglobin. This indicates she might have anemia.
b) The primary work of hemoglobin in blood is to transport oxygen from the lungs to the cells that need it for metabolic activities. When the ability of the blood to transport blood is impaired due to low hemoglobin levels, fatigue and tiredness sets in since enough oxygen is not present for cellular respiration and production of ATP.
c) Hemoglobin is an iron-rich protein that helps red blood cells carry oxygen from the lungs to the rest of the body. If iron intake is not sufficient, anemia could result. Therefore, it is important that iron-rich meals are incorporated into our diet.
So her MD would need to know how much of iron she has been having in her diet.
Song learning in developing songbirds is impaired by lesions of the _______, but lesions in this location have no effect in adulthood.
Answer:
The question is incomplete because the options are not given but the options are gotten from another website.
a. LMAN.
b. H VC.
C. R A.
d. Hippocampus
Explanation:
It is LMAN leison because lateral magnocellular nucleus of the anterior nidopallium (LMAN) function in producing modulatory during song development in song birds .
Lesion means damage in organ or tissue that function
A damage in the organ or tissue of LMAN cause difficult in song learning development in song birds because the LMAN will not be able to perform it's function due to those damages and there is less song variability.
Cognitive diversity refers to the similarities in viewpoints and methods in problem solving.

The cell theory is a well-tested explanation of observations that was formed from the contributions of several different scientists.
The cell theory was developed through extensive library research because it would be impossible to test all living things for the presence of cells.
Answer: C
Explanation:
The statement 'the cell theory is a well-tested explanation of observations that was formed from the contributions of several different scientists' BEST explains how the cell theory was developed.
The cell theory is a widely accepted theory that represents the foundational basis of cellular biology.This theory (cell theory) was initially developed by Matthias Schleiden and Theodor Schwann in 1838.The cell theory states that:
All living things are composed of cells. The cell is the basic structural and organizational unit of life.All the cells originated from pre-existing cells.In conclusion, the statement 'the cell theory is a well-tested explanation of observations that was formed from the contributions of several different scientists' BEST explains how the cell theory was developed.

Which method provides biochemical evidence that cells have begun to differentiate?
A. Observation with a light microscope
B. Observation with an electron microscope
C. Examination of the DNA sequence
D. Analysis of the proteins
Answer:
D. Analysis of the proteins
Explanation:
According to the research, the analysis of the proteins provides biochemical evidence that cells have begun to differentiate.
What is the analysis of the proteins?It is a method that measures the set of different proteins present in the blood.
The proteins that regulate cell differentiation processes are called cyclins that help control cell multiplication and cyclin-dependent protein kinases.
Therefore, we can conclude that according to the research, the analysis of the proteins provides biochemical evidence that cells have begun to differentiate.

DOES BORON HAVE CATIONS OR ANIONS PLZ HELP ME!!!
Answer:
umm
Explanation:
Ringer’s solution is often given intravenously to patients experiencing dehydration. It contains water, 131mMol/L sodium, and 111mMol/L chloride ions. Why wouldn’t distilled water be used? Why doesn’t the solution contain higher amounts of sodium, chloride, and other electrolytes?
Answer:
It is important to maintain the osmolality of the blood (plasma) at an appropriate level to prevent osmosis into and out of cells by keeping the intra- and extracellular fluids isotonic;
Too much water entering a cell can lead to lysis and too much leaving a cell results in shrinkage, both of which are detrimental.
Ringer's solution seems to be osmotic pressure to animal bodily excretions. Distilled water has the highest moisture contents but lacks critical minerals.
Whenever the individual receives intravenously liquids, a huge volume of pure water has been injected into the vein, causing hypotonicity of blood cells as well as worsening dehydration.Ringer's solution would be used to replenish electrolyte balance. If somehow the solution has a high concentration of sodium, calcium ion, as well as electrolytes, it'll no longer be isotonic towards the participant's bodily fluid.
Thus the response above is correct.
