Which of the three traits considered in this film (bipedality, extensive tool use, and large brains) were present in the 3.2-million-year-old Australopithecus fossil (Lucy)?A. Lucy was a bipedal hominid with a brain size similar to that of modern humans, demonstrating that bipedality and larger brains evolved together.B. Stone tools were found in the same rock layer where Lucy was found, showing that members of this species were making and using tools 3.2 million years ago.C. Lucy was a bipedal hominid, and its discover provided evidence that bipedality preceded the evolution of a larger brain size and extensive tool use.D. Lucy had a large brain, but there is no evidence that it used tools or that it walked mostly on two legs.
Answer:
I think the answer is C
Explanation:
C
Lucy was a bipedal hominid, and her discovery provided evidence that bipedality preceded the evolution of larger brain size and extensive tool use.
How important is Lucy's discovery?It is one of the most complete fossils ever found. Because it is a very complete skeleton, compared to the fragments that are usually found, Lucy allowed scientists to better understand human ancestors and study size, shape and locomotion.
Whit this information, we can conclude that Lucy was a bipedal hominid, and her discovery provided evidence that bipedality preceded the evolution of larger brain size and extensive tool use.

THE ANSWER IS FALSE!!!
Answer:
FALSEEEEEE. I took the test.
Answer:
false
Explanation:
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.

Why does meiosis have two stages of cytokinesis? Four daughter cells are produced so the cell needs to divide twice, The chromosomes get mixed up so the cell divides more to get them back in order, The chromosomes cross over so the cell divides to break them up, or The daughter cells are 2n so there needs to be 2 divisions.

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.

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.

how the illustration and student observations support the cell theory?
Answer:
By observing the organism under microscope.
Explanation:
Both the illustration and student observations support the cell theory because with the help of microscope. If the student observe a material, he will be able to see small compartment from which the material is formed. Cell theory states that all living organisms are composed of small units called cells. The student also see the organisms under the microscope and find out that the organism is made of cells.

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
Which of the following base pair sequences could be produced in DNA replication?
AGTCAT
TCAGTA
AGTCUT
TCUGIA
AGTCAT
UCAGUA
AGTCAT
CTGACG
The base pair sequence that could be produced in DNA replication is AGTCAT, UCAGUA. The correct option is c.
What are DNA sequences?The DNA sequence is the sequence or pairing of DNA bases. RNA and DNA both are genetic materials and both are made up of nucleic acids made up of deoxyribose acid and iron is made up of ribonucleic acid.
DNA and RNA both contain four bases that are joined with hydrogen bond RNA contain uracil in the place of thymine and DNA contain timing all other bases are same.
The base pairs are complementary to each other: Thymine: Adenine and cytosine: guanine.
But in RNA, it is uracil with adenine. Guanine and cytosine are the same. So the adjacent base pairs will be:
AGTCAT
UCAGUA
Therefore, the correct option is c. AGTCAT, UCAGUA

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.
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.
