6. Which marrow was denser (had more mass in the given volume)? What impact would that have on the overall density of the bone?
Answer:
The beef bone marrow was denser than the chicken bone because it had more mass in the given volume. Since the chicken must fly, it cannot have its bones weighing it down on the land. However, cows must find grass on land and travel long distances. This would increase the overall density of the bone.

Why the Chimpanzee's diploid number is 24 instead of 48.
I am not sure if the following table supposes me to write 2 (N) on here...
Thank you very much
Answer:
It has 24 pairs and 48 number of chromosomes.
Explanation:
The Chimpanzee's diploid number of chromosome is 24 pairs instead of 48 because of the resemblance with the human cell that have 23 pairs of chromosome. The Chimpanzee has 24 pairs of chromosome or another words we can say that chimpanzee has 48 number of chromosomes not pairs. Humans have 23 pairs whereas apes have 24 pairs of chromosome. The theory suggested about this close number of chromosomes is that at some point two ape chromosomes fused to make a single human one.

3.2.2 Chromosome
A chromatid
B spindle fibre
3.2.3 Phases in the cell cycle
A interphase
B mitosis
3.2.4 Tumour
A benign
B malignant
3.2.5 Bone cancer
A carcinoma
B leukaemia
Answer:
3.2.1 Mitosis - Both A and B
3.2.2 Chromosome - Both A and B
3.2.3 Phases in the cell cycle - Both A and B
3.2.4 Tumor - Both A and B
3.2.5 Bone cancer - B only
Explanation:
1. Mitosis is a process of cell replication , in which one cell divides into two identical daughter cells having the same number of chromosomes. In mitosis, the two new cells are genetically identical. Copies of the chromosome (containing the DNA) are made and distributed equally to each cell. Some organisms such as bacteria reproduce entirely by mitosis.
In cloning, an organism that is genetically identical to another organism is made from that original organism. Cloning can occur naturally or may be done by man artificially. In nature, many organisms produce clones through asexual reproduction for example bacteria produces clones by mitotic binary fission.
Therefore, the phrase mitosis, applies to both A and B.
2. Chromosomes are structures found within the nucleus of cells that contain the genetic material of the organism. The chromosomes are composed two identical structures called chromatids thar are joined together to at a constricted point known as centromere.
During cell division, long fibres extend from the centroiles at the ends of the cell to the centromere of the nucleus in order to pull them apart. These long fibres are known as spindle fibres.
Therefore, the phrase, Chromosome, applies to both A and B
3. The phases in the cell cycle are divided into two major stages : interphase and Mitosis. In interphase, the cell grows and makes a copy of its DNA.
In mitotis, the cell DNA divides into two sets, the cytoplasm divides, forming two new cells.
Thus, phases of cell cycle applies to both A and B
4. Tumours are abnormal growths occurring in any part of the body which may be benign or malignant.
Benign tumours are harmless growth which do not have spread out to other tissues to form various cancers.
Malignant tumors spread out from their point of growth to other tissues leading to cancer in these other tissues and organs.
Therefore, tumors applies to both benign and malignant.
5. Bone cancer refers to abnormal growth of bone cells.
Carcinomas are cancers of the skin and tissue lining of organs.
Leukaemia are cancers affecting the bone marrow, whereby the bone marrow makes abnormal white blood cells, red blood cells and platelets.
Thus, bone cancer only applies to B.
⦁ Arrange these statements in the right order to describe process of inhalation.
____ Air is drawn into the lungs
____ Air pressure in the chest cavity decreases
____ Lungs expand
____ The diaphragm contracts and flattens
____ The muscles between the ribs contract to move the ribs up and out
Answer:
air is drawn into the lungs
lungs expand
the muscles between the ribs contract to move the ribs up and down
air pressure in the chest cavity decreases
the diaphragm contracts and flattens
Inhalation has been part of respiration. It includes drawing air into the lungs that expand the lung cavity by pulling the ribs leading to contracting the diaphragm followed by a decrease in lung pressure. Thus the correct order is 1, 3, 5, 4, and 2.
What is inhalation?Inhalation is the respiratory process to inhale oxygen inside the respiratory system for the cellular and respiratory processes. At first, the air is drawn into the lungs followed by expansion of the lungs.
This causes the ribs muscles to move up and down to accumulate the volume. This movement causes the diaphragm to flatten and contract which allows the oxygen to take place in the lungs that decreasing the air pressure in the cavity.
Therefore, the air is drawn inside the lungs in inhalation.

Explanation:
So you can mark the other person :)
Anything that contains atoms emits infrared radiation. Therefore, option (D) is correct.
What is Infrared radiation?All objects, living or non-living, emit some amount of infrared radiation, which is a type of electromagnetic radiation with wavelengths longer than those of visible light. The amount and wavelength of the infrared radiation emitted by an object depends on its temperature, with hotter objects emitting more and shorter-wavelength infrared radiation.
This is the principle behind the use of infrared cameras and thermal imaging technology to detect and measure heat in a variety of applications, including night vision, medical imaging, and industrial inspections.

What do you think would happen to the population of rabbits, if the population of foxes decreased?
Answer:
the population of rabbits might increase
Explanation:
With less predators to eat them, the rabbit population will likely go up if the fox population decreases; assuming there are favorable factors such as plenty of food and habitat for the rabbits. At some point, there is a maximum limit to the number of rabbits that a certain location can hold. Once this limit is reached, (some of) the rabbits will migrate elsewhere or unfortunately die off.
As the rabbit population increases, the fox population may rebound and start increasing again. This is due to more food being available to the smaller amount of foxes, and there is less competition for food. So the rebounding fox population will likely bring down the rabbit population to a point where food will get more scarce for the foxes. This cycle repeats itself where one population increases while the other decreases, and vice versa. They are very strongly linked together. It's also possible that both will increase together if environmental factors are favorable, but they could easily decrease together if a habitat is being destroyed for instance. It will depend on the circumstance.

describe how energy for the photosynthesis reaction is gained by plants (2)
please help
Answer:
Plzzzz answer fast......
The energy for the photosynthesis reaction is gained in the first stage of the reaction.
There are 2 stages in photosynthesis:
The light-dependent stageThe light-independent stageDuring the light-dependent stage, an electron in the molecules of chlorophyll gets excited and gets knocked off as a result of photon absorption. A molecule of water is split and the electrons released replace the one lost by the chlorophyll after traveling through the electron transport chain.
The energy from the traveling electron is used to reduce NADP+ to NADPH while the splitting of water to H and O means that a proton gradient is established between the stroma and the thylakoid lumen of the chloroplast. The electrochemical gradient thus created is used by ATP synthase to generate ATP from ADP.
The two chemicals, ATP and NADPH, are then utilized as energy sources for the light-independent reaction.

A person has type B blood the possible blood types of his parents can be A x B, A x AB, O x AB, B x AB, AB x AB, B x O, B x B.
What is blood types?The four main blood types are A, B, AB, and O. Your blood type is determined by the genes your parents gave you.
Red blood cells with blood group A antigens have anti-B plasma antibodies. Plasma from people with blood group B contains anti-A antibodies and B antigens.
Blood group O has both anti-A and anti-B antibodies in the plasma but no antigens. Both A and B antigens are present in blood group AB.
A person with type B blood may have parents who have the blood types A x B, A x AB, O x AB, B x AB, AB x AB, B x O, or B x B.

(a) Describe why monitoring the growth rate of the E. Coli-M bacteria is a useful indicator of the effect of the glycolytic enzyme mutation on the bacteria.
Answer:
The monitoring the growth rate of E.Coli bacteria is a useful indicator of the effect of glycotic enzyme mutation on the bacteria as the flow of intracellular metabolic components depends on the availability of carbon. Hence the change in carbon source can change the glyclyotic enzyme mutation up or down.
Explanation:
Continuous culture is a method that can be used by the researchers for determining whether mutation affects the growth rate of E.Colin-M bacteria
If the growth medium contains higher concentration of acetate,then the growth of the bacteria will be inhibited without inhibiting its central metabolism.
When E.Coli grows ,it secrets acetate. This mechanism is called overflow mechanism. Regulatory interactions mediated by acetyl-phosphate plays a major role in inhibiting growth by acetate. The uncoupling effect of organic acids or perturbation of the anion composition of the cell is a major reason for growth inhibition.
Edwin Hubble was an American astronomer who played a crucial role in collecting evidence to support the theory that the universe is constantly expanding outward and is not simply static. He used light from distance stars to calculate their movement.
Meanwhile, around this same period of time, a Russian physicist by the name of Mikhail Lomonosov worked tirelessly in his lab studying different chemical reactions. Lomonosov would later help in developing the Law of Mass Conservation which states that during a chemical reaction the total mass of the substances before the reaction is equal to the total mass after the chemical reaction.
How are the methods used in the pursuit of a scientific explanation different between Edwin Hubble and Mikhail Lomonosov?
A) Edwin Hubble carefully identified and manipulated variables to answer questions; Mikhail Lomonosov made observations about the natural world.
B) Edwin Hubble made observations about what he studied; Mikhail Lomonosov did not
C) Edwin Hubble and Mikhail Lomonosov both used scientific equipment and collected evidence
D) Edwin Hubble made observations about the natural world; Mikhail Lomonosov carefully identified and manipulated variables to answer questions.
Answer:
C
Explanation:
These type of questions leave a great deal to be desired. There is no mention of which way Hubble used and manipulated data. He studied the variations in light to determine his conclusions.
Nor is there any mention of what Lomonosov did to come to the conclusion that conservation of mass is a constant.
We don't know what was done to get the results. Hubble was studying the universe; the conclusions made by Lomonosov depended on lab equipment that was very delicate (I'm assuming). I doubt he manipulated variables. He measured what he got.
I think the answer is C, but the question has so many assumptions that it is hard to know what answer to pick.
