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.

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.

Which occurs during the light-dependent reactions of photosynthesis?
a.Light energy is absorbed and then converted into chemical energy in the form of ATP and NADPH.
c.Organic molecules, such as proteins, lipids, and nucleic acids, are produced.
d.None of the above
b.ATP and NADPH are used to make glucose
Answer:
In light-dependent reactions the energy from sunlight is absorbed by chlorophyll and converted into chemical energy in the form of electron carrier molecules
Explanation:
Like ATP and NADPH light energy is harnessed in Photosystems I and II both of which are present in the thylakoid membranes of chloroplasts
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.
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.

Sam is out for a long run on a hot day. He is dehydrated and does not have water with him. As he tries to maintain a high exercise intensity, his body is likely experiencing the dual cardiovascular demand.Which two factors make up this demand?
a. The need to pump additional blood to the surface of the skin b. The need for additional hydration c. The need for more ATP d. The need to produce more sweat e. The need to pump additional blood to working muscles f. The need for additional blood plasma
Answer:The dual cardiovascular demands includes: Option A (The need to pump additional blood to the surface of the skin.) And
Option E (The need to pump additional blood to working muscles)
Explanation:
When an individual is performing exercise under the hot atmosphere, the following demands are required:
--> there would be physiological increased demand of the skin to prevent further dehydration .
--> there would be increased energetic demands for muscular activities.
1.) The blood flow to ACTIVE MUSCLES during prolonged exercise under a hot day.
There is increase in carbon dioxide and hydrogen ions, decrease in oxygen levels will cause the smooth muscles of the blood vessels located at the active muscle sites to relax. This enhances the in flow of blood supply oxygen which is needed for the generation of Adenosine triphosphate (ATP) for energy. This requires a greater cardiac pumping capacity.
2) The flow of blood to the skin during during prolonged exercise in a hot day.
To avoid dehydrations during exercise which occurs through the lungs and skin, there is increased cardiac output to remove excess heat generated through thermoregulation of cutaneous circulation.
The hypothalamus:_______
a. initiates voluntary movements.
b. functions in speech recognition
c. controls autonomic nervous system and regulates thirst
d. is regulated by the pituitary gland.
e. plays a very minor role in the maintenance of homeostasis
Answer: Option C..
controls autonomic nervous system and regulates thirst
Explanation:
Hypothalamus controls autonomic nervous system and regulates thirst because it is above the brain stem and it receive autonomic regulatory signals or information , then it then act to integrate and controls autonomic nervous system. The autonomic nervous system help to regulate different types of body functions like sexual arousal, heart rate, pupilatory rate, digestion rate , respiratory rate e.t.c.

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.

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.
