Given what we know about the behavior of gases like helium, we can confirm that the small tank of helium was able to fill so many balloons because the helium expanded to fill its new container, which is the balloon.
Helium is a chemical element known as a noble gas. Like all other elements in a gaseous state, the atoms that comprise helium are spaced apart. This allows the gas to be compressed, a property that manufacturers of the gas take advantage of since they can compress a large amount of gas into a small container.
This is precisely what is happening in the question. The small tank of helium, despite being small in size, contains a large amount of compressed helium gas. Therefore, once it is released from the container, the gas expands to fill its new container, which in this case is the balloons, because of this, a relatively small tank of helium was able to fill many large balloons.

Stickleback fish protect themselves from predators with a thick covering of brownish plates. They feed on
small aquatic organisms and are preyed upon by bigger fish like trout. In a certain lake, the number of
stickleback fish was documented over a period of 30 years. During this time, the clarity of the lake water
also changed.
1. How did the occurrences of the different traits change over the 30-year period? Use evidence from
the graph to support your answer. Using what you know about natural selection and adaptation, what
generalization can you make based on these changes?
Explanation:
scam fakeeee
just kidding the answer is
every time the differences will change because of the large fishes which kill the small ones and the fishes het big like in one big fish there will be 100 of small fishes like the megladon
during this blood also leaks and the colour of the lake changes
Answer:
In each instance, the variations in fish populations are subject to change due to the predation of larger fish on smaller ones. As a result, the surviving fish grow larger, akin to the manner in which the Megalodon can have hundreds of smaller fish within its body. This process can also result in the release of blood, which has the potential to alter the color of the surrounding water body.
Explanation:
Under the hypothesis of blending inheritance, what color(s) would the offspring of a black cat and a white cat be
Under the hypothesis of blending inheritance, the offspring of a black cat and a white cat would be GREY. This theory is not now accepted.
Blending inheritance is an erroneous theory from the 19th century that proposed that offspring inherit phenotypic traits as 'average values' observed for such traits in their parents.
Mendel's laws of heredity (i.e., the Law of Segregation and the Law of Independent Assortment) showed that blending inheritance is based on erroneous concepts.
Moreover, incomplete dominance is an inheritance pattern different from blending inheritance because incomplete dominance refers to the observation that in certain traits both gene variants or 'alleles' are expressed in heterozygous individuals.

Recall what you know about hypertonic, hypotonic, and isotonic solutions. When an environment is hypotonic, what happens
to the cell?
When a cell is submerged in a hypotonic solution, water osmosis causes the cell to become flaccid.
What is osmosis?
A semi-permeable membrane is used in the process of osmosis, which allows solvent molecules to move from a solution of low concentration to a solution of high concentration.
Osmosis is a passive process that doesn't require any energy to complete. In order for the concentrations on either side of the membrane to be equal, molecules must shift from an area of greater concentration to one of lower concentration.
Any solvent, including gases and supercritical liquids, can go through the osmosis process.
When solute concentrations inside and outside of the cell are equal, an isotonic solution has been created.When the concentration of solutes outside the cell is higher than within, the solution is said to be hypertonic. When the concentration of solutes inside the cell is higher than outside, the solution is said to be hypotonic.
Therefore, when a cell is submerged in a hypotonic solution, water osmosis causes the cell to become flaccid.

what hormone directly opposes the actions of natriuretic hormones?
The hormone that directly opposes the actions of natriuretic hormones is aldosterone.
Aldosterone is a hormone produced by the adrenal glands, specifically the adrenal cortex. It acts on the kidneys to promote the reabsorption of sodium ions and the excretion of potassium ions.
Natriuretic hormones, on the other hand, promote the excretion of sodium ions and the reabsorption of potassium ions in the kidneys, leading to increased urine production and decreased blood volume.
Therefore, aldosterone counteracts the effects of natriuretic hormones by increasing sodium reabsorption and reducing potassium excretion, which helps to retain water and maintain blood pressure.
In summary, while natriuretic hormones promote sodium excretion and water loss, aldosterone works in the opposite direction by promoting sodium reabsorption and water retention.

What is the major consideration in setting the lower limit of cell size?
A. The cell size must be small as to fit all the processes and structures to support life.
B. The cell must be large enough to fight the pathogens.
C. The cell must be large enough to attach to a substrate.
D. The lower limit should be small enough for the cell to move in the fluid efficiently.
Answer:
c
Explanation:
The lower limit should be small enough for the cell to move in the fluid efficiently. Therefore, option (D) is correct.
The major consideration in setting the lower limit of cell size is the need for the cell to move in fluid efficiently. As cells become smaller, their surface area-to-volume ratio increases, allowing for more effective exchange of nutrients, gases, and waste products across their membrane.
This is particularly important for cells living in fluid environments where diffusion plays a crucial role in these exchanges. Small cells have an advantage in absorbing and expelling substances due to their larger surface area relative to their volume. Therefore, the efficiency of nutrient uptake and waste removal becomes more effective with smaller cell sizes, making efficient movement in fluid environments a significant factor in determining the lower limit of cell size. Thus, option (D) is correct.

the countries with the highest fertility rates are also the ones with the highest infant mortality rates. which one causes which and how do we know?
Answer: Higher infant mortality rates cause higher fertility rates.
Explanation:
Countries with high infant mortality rates are usually countries where families rely on children to help out the family. High infant mortality rates and a need for children means that those people will continue to try to have children until they have some that survive. If more children die, and people need to have more children, there will be a higher fertility rate.

Explanation:
If the first nucleotide after the promoter on the bottom DNA strand is changed from C to T, what would the resulting nucleotide be on the mRNA
When the DNA's C is changed to T, the corresponding nucleotide on the mRNA strand will be A (adenine) to maintain the complementary base pairing.
Nucleotides encode genetic information in DNA. Due to complementary base pairing laws, DNA sequence alterations impact mRNA transcript nucleotides. If the first nucleotide following the promoter on the bottom DNA strand changes from C (cytosine) to T (thymine), the matching mRNA strand nucleotide becomes A.
Because C pairs with G (guanine) in DNA and RNA. T in DNA matches A in RNA owing to complementary pairing. The DNA sequence will influence the mRNA sequence during transcription, which may impact the protein synthesised during translation.
