A 12 pound shot put and a small metal BB are dropped from a tall tower, inside a vacuum chamber,
and into a deep pool. Compare how the objects fall in these three scenarios.
Given what we know, we should observe the objects falling at the same speed in both the tower and vacuum scenarios, but not in the water.
What affects the speeds at which these objects fall?The falling speeds in both air and a vacuum will be the same for both objects. This is because falling speed is determined by gravity and is independent of the mass of the objects falling. The same will occur in water if and only if the densities of the two objects are equal.Therefore, given that we can safely assume that the densities of the two objects are different from one another, we can confirm that while the objects will fall at the same speed in air and in a vacuum, this will not be the case in the deep pool.

The lactose operon is likely to be transcribed when.
Answer:
the lac operon can only be transcribed at high levels when glucose is absent.
Explanation:
This strategy ensures that bacteria only turn on the lac operon and start using lactose after they have used up all of the preferred energy source (glucose).
High levels of cAMP are required for the genes of the lactose operon to be transcribed.
How are the genes of the lactose operon transcribed?Cyclic AMP (cAMP) is required for the transcription of all operons that are inhibited by glucose catabolism.
The catabolite-activating protein (CAP) is a dimer that, when bound to cAMP, activates and stimulates the transcription of the lactose operon genes, so that the CAP-cAMP activating protein is necessary for the binding of RNA-polymerase to the promoter of the lactose operon genes.
Therefore, we can conclude that high levels of cAMP are needed for the genes of the lactose operon to be transcribed.

What is true for the DNA fragment band closest to the positive end of the gel? The truth of the DNA fragment band that is closest to the positive end of the gel is that it is the smallest DNA fragment, hence the reason it moved faster to the positive end than the rest 7.
Explanation:
i hope this answer your question if this wrong or correct please let me know/
You can discriminate between DNA fragments of various lengths using electrophoresis.
What results in DNA fragments in positive end?The DNA fragment band that migrates most fast to the positive end of the gel is actually the smallest DNA fragment, which explains why it did so 7.
When an electric current is applied to the gel, the negatively charged DNA will move in the direction of the positively charged electrode.
The DNA fragments are organized in size order because shorter DNA strands travel through the gel more quickly than longer ones.
The DNA fragment band that is closest to the gel's positive end is really the smallest DNA fragment, which explains why it migrated there more quickly than the other bands did 7.
Therefore, The lighter and shorter DNA fragments are closest to the gel's positive end.

What happens to the energy produced in photosynthesis.
Answer:
Photosynthesis uses light energy to convert carbon dioxide and water into glucose and oxygen gas. Each molecule of glucose essentially “stores” up to 38 molecules of ATP which can be broken down and used during other cellular reactions. ATP, or adenosine triphosphate, is the form of chemical energy cells use to function. Cellular respiration is the complementary reaction to photosynthesis, because it is the reaction that cells use to break down glucose molecules and release ATP. The potential energy stored in the molecular bonds of glucose becomes kinetic energy after cellular respiration that cells can use to do work like move muscles and run metabolic processes.
The amount of tension in the ventricular myocardium immediately before it contracts is called _________.
Given what we know, we can confirm that the amount of tension in the ventricular myocardium immediately before it contracts is called the preload.
What is ventricular myocardium tension?The ventricular myocardium refers to the cells that make up the ventricles of the heart. These would be the lower chambers in charge of ejecting the blood from the heart so that it may circulate. The tension we are referring to is caused by the stretching of these ventricles as they fill with blood and are preparing to contract.
Therefore, we can confirm that the preload is the name given to describe the amount of tension in the ventricular myocardium immediately before it contracts.

a) The genotype that regulates skin color is attributed to a single rigid phenotype.
b) There is a different gene that encodes for each type of skin color.
c) Flexibility in gene expression leads to differences in skin color and response.
d) Skin color is varied because individuals have rigid genotypes for skin color.
Answer:
c. Flexibility in gene expression leads to differences in skin color and response.
Explanation:
I took the quiz.
There is a different gene that encodes for each type of skin color, so after the same amount of exposure, some people can burn their skin, while others tan to a darker color, hence option B is correct.
How skin color is genetically determined?The amount, kind, and packaging of melanin polymers that melanocytes release into keratinocytes result in variations in skin and hair color, which are primarily genetically determined. The pigmentary phenotype is difficult physiologically and genetically.
In persons with darker skin, melanin, which is produced by skin cells called melanocytes, is the main factor in determining skin color. In fact, more than 150 genes have now been shown to directly or indirectly affect skin color.
Therefore, there is a different gene that encodes for each type of skin color.

The first step in the figure walkthrough was gamete formation from the p1 generation. What gametes would be produced from the p1 parent ggww?.
Assuming these genes are not linked and assort independently, from the parental genotype P1 ggww, four gametes gw will be produced.
GERM CELLS
Germ cells divide by mitosis and meiosis.
Through mitosis, they originate more germ cells.Through meiosis, they give place to haploid gametes, called sperm and egg cells. This process is known as gametogenesis.MEIOSIS
Meiosis produces four daughter haploid cells (n) from a diploid germ cell (2n).
Each daughter cell is haploid because they have half the number of chromosomes of the original one.
Meiosis is completed in two phases.
A first reductive phase, after replication, A second not-reductive phase.Gamete formation involves the random and independent segregation of the alleles.
During anaphase I (meiosis) occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell.
This separation generates different chromosomal combinations in the daughter cells.
There are two alternatives per homologous pair.
The number of gametes with different combinations is 2ⁿ, where n = number of homologous pairs.
In the exposed example, assuming that these genes are not linked -they are placed in different chromosomes- and assort independently from each other, the four possible gametes would be gw.
Allele combination is as follows
Parental) ggww
Gametes) gw, gw, gw, gw

Which was not a source of heat for early Earth?
A.asteroid and meteorite bombardment
B.hydrothermal energy
C. gravitational contraction
D.radioactivity
Answer:
hydrothermal energy
Explanation:
It was not invented
Earth was extremely hot after it formed. There were three likely sources of this heat: Earth's gravitational contraction, radioactivity, and bombardment by asteroids, meteorites, and other system bodies.
Hydrothermal energy was not a source of heat for early earth.
What was early earth?The Earth, along with the other planets in our solar system, originated more than 4 billion years ago.The early Earth had no ozone layer and was most likely quite hot. There was also no free oxygen on the early Earth.Few things could have survived on the early Earth without an oxygen environment. Anaerobic bacteria were most likely the first living organisms on Earth.The early Earth had no seas and was constantly bombarded by meteors and asteroids. Volcanic outbursts were also common. Volcanic eruptions emitted water vapor, which cooled to form the seas.As solar radiation broke water molecules and cyanobacteria began photosynthesis, the atmosphere gradually became increasingly oxygen-rich. Eventually, the atmosphere evolved into what it is now, which is oxygen-rich.Around 2 billion years ago, the first sophisticated species appeared on Earth.
