As a cell grows, the surface area to volume ratio (sa:v) decreases. in order to maintain homeostasis, the cell must divide or die. the decreased sa:v ratio would affect all but
Cell division is the process of the parent cell forming daughter cells. The decreased SA: V ratio does not affect the stages involved in cell division.
What is SA: V?The surface area to volume ratio gives the size of the cell. The decrease in this ratio of the surface area and the volume causes the cell to divide or die. This ratio affects the rate of osmosis.
The decreased ratio also alters the signaling of the proteins and the cytoskeleton transport system of the cell, but the number of cell division phases is unaffected by the ratio.
Therefore, the cell division phases are unaffected by the SA: V ratio.

Research the use in the military of magnetic anomaly detectors, mads. write a brief 300-word essay answer the following questions on mads. what is the main idea behind mads? what can be detected by using mads? a brief history of the mad development.
Answer:
MADs are Magnetic Anomaly Detectors and the main idea behind MADs is that they follow the principle rule that objects with metallic properties get in the way of the magnetic lines of the Earth's forces. Metallic things such as submarines are normally detected using MADs. MAD development started around 1917. The function of the MADs was to identify anomalies in the Earth’s magnetic field that were caused by submarines. Later on, around 1941 in the US and Britain, there was a development of magnetic detection devices. These were meant to measure Earth’s magnetic field. So ultimately after this in 1943, MADs were now installed in ASW aircrafts. However, due to its limited range and its incapacity to detect the magnetic variances of different sources, MADs started to be used along with sonobuoys which was the opposite of what they were intended to be used for.
Explanation:
The primary concept underlying MADs, which stand for Magnetic Anomaly Detectors, is that they adhere to the general notion that things with metallic qualities obstruct the magnetic lines of the Earth's forces.
What is Magnetic Development?MADs are used to find metallic objects, like submarines. Around 1917, MAD development first began.
The purpose of the MADs was to locate submarine-related magnetic anomalies in the Earth's magnetic field. Later, about 1941, magnetic detecting technology developed in the US and Great Britain.
These were designed to gauge the magnetic field of the planet. As a result, MADs were eventually deployed in ASW aircraft in 1943. However, MADs have a restricted range and are unable to detect the magnetic variations of many sources.
Therefore, The primary concept underlying MADs, which stand for Magnetic Anomaly Detectors, is that they adhere to the general notion that things with metallic qualities obstruct the magnetic lines of the Earth's forces.

Explain the effect a change in temperature, volume, and pressure has on gas particles. then explain if these changes are an example of a direct or an inverse relationship.
The increase in pressure, with volume constant will increase the temperature. The increase in volume, with pressure constant will increase the temperature. The increase in pressure, with temperature constant will decrease the volume.
What are pressure, temperature and volume?These three are the characteristics of a gas. A gas is always in some pressure, having some volume and temperature.
According to the ideal gas law,
pV =nRT
Here, p is the pressure, V is the volume, n is number of moles, R is the universal gas constant and T is the temperature.
The volume of a gas is directly proportional to its absolute temperature when pressure is constant, according to Charles's law.
The volume of a gas is inversely proportional to its pressure when temperature is constant according to the Boyle's law.
Hence, the increase in pressure, with volume constant will increase the temperature. The increase in volume, with pressure constant will increase the temperature. The increase in pressure, with temperature constant will decrease the volume.

Based on above scenario of their ages and cost of insurance for their age and length of policy, the total premium is said to be $2,484.
What is the premium about?Note that in the scenario given above;
Joe annual premium is said to be = Cost for 32 year old with 15 year policy x Policy amount / 1,000
So therefore, it will be = 3.32 x 300,000 / 1,000
= $996
That of Melinda annual premium = Cost for 29 year old with 20 year policy x Policy amount / 1,000
So therefore, it will be = 4.96 x 300,000 / 1,000
= $1,488
Therefore the Total annual premium = Joe premium + Melinda premium
= 996 + 1,488

Drag the tiles to the correct locations on the equation. not all tiles will be used. a californium atom undergoes nuclear fission. complete the equation by filling in the missing parts.
Nuclear fission is the splitting of the atomic nucleus into more nuclei. The product of the californium atom fission is palladium,¹¹⁴₄₆Pd.
What is nuclear fission?Nuclear fission is the breakdown of the atomic nucleus into two or more atomic nuclei including the gamma photons that release high energy.
The californium atom will absorb a neutron and release two small nuclei and three neutrons.
We know,
The atomic number of californium atom (Cf) = 98
The atomic mass of the californium atom (Cf) = 252
The atomic number of Tellurium (Te) = 52
The atomic number of Tellurium (Te) = 136
The atomic mass of the unknown element is calculated as:
[(252 + 1) - (136 + 3)] = 114
An atomic number of the unknown element is calculated as:
98 - 52 = 46
Hence, the unknown element is palladium (Pd) as it has atomic number 46.
The nuclear fission of the californium atom is shown as:
[tex]\rm ^{252}_{98}\; Cf + ^{1}_{0} n \;\rightarrow \;^{114}_{46}\;Pd +^{136}_{52}\;Te +3^{1}_{0}\;n[/tex]

Select the correct answer. what is the value of x in the triangle? an isosceles right triangle with two legs of length 10 and hypotenuse of length x a. b. c. d. e.
Answer:
[tex]10\sqrt{2}[/tex]
Explanation:
There is a diagram attached which models the situation.
Since the given triangle is right, we are able to use the Pythagorean Theorem, which states when a and b are the legs of a right triangle and c is the hypotenuse:
[tex]a^{2} + b^{2} = c^{2}[/tex]
We can plug in the given values. Since both legs have a value of ten, we can say:
[tex]10^{2} + 10^{2} = c^{2}\\100 + 100 = c^{2}\\200 = c^{2}\\c = \sqrt{200}[/tex]
We can split 200 into 100 x 2, and [tex]\sqrt{100 }[/tex] is 10, so [tex]\sqrt{200} = 10\sqrt{2}[/tex]
Another way to do this use the given of the triangle being isosceles right. In an isosceles right triangle, the hypotenuse is always [tex]\sqrt{2}[/tex] times the base. So a triangle with legs 10 would have a hypotenuse of [tex]10\sqrt{2}[/tex].
