b. At higher elevations, it would take longer to hard boil an egg, because there is a lower boiling point, the egg is boiling in water at a lower temperature. The correct answer is that at higher elevations, it takes longer to hard boil an egg because the water boils at a lower temperature due to reduced atmospheric pressure.
At higher elevations, the boiling point of water decreases due to the decrease in atmospheric pressure. When hard boiling an egg, this means that the water will boil at a lower temperature, so the correct answer is: b. At higher elevations, it would take longer to hard boil an egg, because there is a lower boiling point, the egg is boiling in water at a lower temperature.
The interaction between atmospheric pressure and boiling point is such that as pressure decreases, the boiling point also decreases. This means that at higher elevations where the pressure is lower, water does not reach as high a temperature when it boils compared to sea level, which implies that cooking an egg thoroughly will require more time as the temperature at which energy is transferred to the egg is lower.
What an organism looks like as a result of its genes is called
The look of an organism according to its genes is called as phenotype of an organism.
Explanation:
The genetic makeup of an organism is usually called as the genotype whereas the physical morphological structure of an organism is termed as a phenotype of an organism. The phenotype usually depends upon the genotype of the organism; this genotype is not visible and hence cannot be known easily.
Whereas a phenotype is easily visible. To know the genotype of an organism the unknown organism should be crossed with a true breeding cross.

-) Some substances are absorbed into the capillaries by active uptake.
0 Explain why active uptake is sometimes necessary
Answer:
Active uptake (which I think you mean active transport) is important when the concentration gradient is against that of a certain substance, so it doesn't cross the membrane through diffusion or passive transport. It is sometimes necessary if a substance needs to move across a membrane but can't do so due to electrical charge or that there is a substance on the other side of the membrane preventing diffusion.
Explanation:
Final answer:
Active uptake is necessary for substances that cannot passively diffuse across cell membranes because they need to move against a concentration gradient. This requires energy in the form of ATP and is fulfilled by the active transport mechanism using cellular proteins as pumps.
Explanation:
Active uptake is sometimes necessary because some substances cannot be absorbed by passive means due to the fact that they need to move against a concentration gradient from areas of lower concentration to areas of higher concentration. This is where active transport comes into play. Proteins in the cell membrane, often referred to as pumps, utilize cellular energy, generally in the form of adenosine triphosphate (ATP), to move the substance.
Additionally, certain nutrients or ions may not be able to dissolve in the lipid layer of the membrane or are too large to pass through the available channels. In the liver, kidney, and central nervous system, as well as for maintaining electrolyte and nutrient balance, active transport is crucial for the movement of such substances. This transport mechanism is vital for cells to take up nutrients and maintain their function, providing the energy necessary for life-sustaining processes.

How do animals store energy
Answer:
Animals store their glucose subunits in the form of glycogen, a series of long, branched chains of glucose.
Explanation:
ANSWER:
Animals store their energy in glycogen form in the body. This energy has been stored in the body for later use to perform the various life functions.
EXPLANATION:
Animals obtain their energy from the food they take in so that the various metabolic processes of the body can be performed. When animals eat food, the glucose present in food is broken-down by "cellular respiration" into an energy molecule known as ATP. When "excess ATP and glucose" are present, these are converted to glycogen by the liver and stored in the body for later use.Poison dart frogs live in the rainforest.

Please HELP!!! what must be present for active transport to occur?
Answer: ATP
Explanation: Active transport requires energy to occur, hence the ATP is necessary for energy.
Active transport, a biological process, requires ATP (energy source), transport proteins (to move substances), and a concentration gradient (higher concentration to lower concentration). A common example is the sodium-potassium pump in cells.
Explanation:Active transport is a process in cellular biology where substances are moved across cell membranes from an area of lower concentration to an area of higher concentration. This is contrary to passive transport, which moves substances along their concentration gradient (high to low concentration)
For active transport to occur, three things are primarily needed:
Adenosine triphosphate (ATP) - This is the energy source required for active transport. ATP provides the energy necessary to move substances against their concentration gradient. Transport proteins - These act like pumps and are integral in aiding the cell move substances across the membrane. They interact with the substances that need to be transported and use energy from ATP to move them against their concentration gradient. Concentration Gradient - The substance being transported is usually moved from an area of lower concentration to an area of higher concentration. This movement is against the gradient, and thus requires energy.
An example of active transport in cells is the sodium-potassium pump, which moves sodium ions out of the cell and potassium ions into the cell, both against their respective concentration gradients.

Mid oceanic ridge is the region along the spreading of the sea floor occurs. Along this ridge, the magma come out to the surface, and lava forms pillow shaped rocks such as pillow basalt. Basalt is the dominant rock type in the oceanic crust.
There occurs striped patterns that are oriented parallel mid oceanic ridge, and this strips depicts the magnetic field of the earth, and it keeps on changing on each eruption of this magma beneath the ocean long this ridge.
The mid oceanic ridge suggests the spreading of the sea floor and the rocks present at this ridge are younger than the rocks that are away from the ridge.
This rocks are comprised of the molten iron material that are present in the mantle and suggest the magnetic field of the earth during the time of eruptions.
Hence, the correct answers are options (1), (2), (3) and (4).
How does the acidity of soil affect flower growth?
Soil pH can affect plant growth in several ways. Bacteria that change and release nitrogen from organic matter and some fertilizers operate best in the pH range of 5.5 to 7.0 making this the optimum pH range. Plant nutrients leach from the soil much faster at pH values below 5.5 than from soils within the 5.5 to 7.0 range. In some mineral soils aluminum can be dissolved at pH levels below 5.0 becoming toxic to plant growth. Soil pH may also affect the availability of plant nutrients. Nutrients are most available to plants in the optimum 5.5 to 7.0 range. PH can also affect the structure of the soil, especially in clay soils. In the optimum range clay soils are granular and easy to work with. However, if the soil is either extremely acid or alkaline clay, soils tend to become sticky and hard to cultivate.
A pH soil test will tell you whether your soil is within the optimum range or whether it will need to be treated to adjust the pH level. Although the optimum range is 5.5 to 7.0 some plants will grow in a more acid soil and some at a more alkaline level.
PH is not an indication of fertility, but it does affect the availability of fertilizer nutrients. The soil may contain adequate nutrients yet plant health may be limited by an unfavorable pH level. On the other hand, builder’s sand, which is devoid of nutrients, may have optimum pH for plant growth.

The sugar pill would be a placebo.
The independent variable is the number of fleas on dogs.
The dogs with the placebo would be the experimental group.
Answer:
The sugar pill is called a placebo.
Explanation:
The placebo), is a harmless sugar pill that would have no effect on any of dogs.
The "control" group is the group that had the actual medication. This is the group they will b checking to see if any fleas or how many fleas r on the control group to gauge the success or failure of the medication.
Option B is correct; the sugar pill is a placebo used as a control in this experiment. The independent variable is the administration of the medication, and the dependent variable is the number of fleas.
In this experiment, the correct answer is that the sugar pill would be a placebo, making option B true. The placebo is used as a control to compare against the group of dogs receiving the new drug to repel fleas. The experimental group receives the new drug, while the control group receives the placebo.
This helps to determine if the drug itself is effective by measuring any differences in flea infestation between the two groups. The independent variable in this experiment is the administration of the medication (new drug vs. placebo), and the dependent variable would be the number of fleas on the dogs. The group given the placebo forms the control group, not the experimental group

M Phase - a period in the life of the cell when it is conducting cell division. Prophase II - the stage in the second meiotic division in which the chromatid pair becomes visible and the nuclear membrane disappears.
The M Phase, which occurs during cell division, is the stage of a cell's existence when it divides into two daughter cells. It includes both meiosis and mitosis in reproductive cells as well as both in somatic cells.
The chromatids become apparent and consolidate during prophase II, which takes place in the second meiotic division. Additionally, the nuclear membrane breaks down, enabling additional division.
The second meiotic division's terminal phase is known as telophase II. The cell divides into two haploid gametes that have only one set of chromosomes each.
Prophase I, in contrast, involves the doubling and condensing of chromosomes during the first meiotic division.
The interchange of genetic material between homologous chromosomes is made possible by the nuclear membrane's breakdown.
Thus, these phases are essential to gamete development and meiosis, which produces genetically varied progeny.
