The element hydrogen has three naturally occurring isotopes, H-1, H-2, H-3. What is the number of protons, neutrons, and electrons in H-3, or tritium?
Answer:
Tritium is one of the three isotopes of hydrogen which contains 1 proton, 2 neutrons, and 1 electron. Out of three isotopes, protium is the most abundant isotopic form of hydrogen constituting about 99.98 % of total isotopic form.
Tritium is a radioactive isotope of hydrogen having a half-life period of 12.3 years which is produced as a byproduct of fission in a nuclear explosion. Naturally, it occurs in a very trace amount.
It emits the beta particle which is having very low energy so cannot penetrate the skin but can be hazardous if inhaled or get absorbed in the skin.

Competition occurs between species when _____.
they fight for mates
their niche is destroyed
they try to share the same niche
a new niche becomes available
Answer: The correct answer for the fill in the blank is- They try to share the same niche.
According to competitive exclusion principle, two species when present in the same area, try to compete for the same limiting resource like food. The species having better advantageous trait over the other survive and exclude the other one. In other words, the second species is either eliminated or shifts to some other niche.
This principle is also called Gause's principle.
Thus, competition occurs between two species when they try to share the same niche.
Answer:
they try to share the same niche

Explanation:
The allele for a widow’s peak has complete dominance over the allele for a straight hairline (w). What is the probability of a man with a straight hairline (ww) and a woman with a widow’s peak (WW) having an offspring without a widow’s peak?
0 percent
75 percent
25 percent
50 percent
Option A is the correct answer.
D. 0 percent
Explanation:As the widow's peak is dominant over straight hairline (w). And the mother is homozygous recessive dominant for widow's peak. So, her all children receive one dominant W from their mom so they all will be having widow's peak.
You visit a farm and notice that white chickens lay white eggs and colored chickens lay brown eggs, so you decide that only white chickens lay white eggs. What type of reasoning is this?
a) inductive
b) deductive
Answer
Inductive
Explanation
Its a logical process in which a number of premises all believed true or sometimes found true most of the time and combined to come up with specific conclusions. Its mostly used in applications that do involve behavior, forecasting and makes broader generalization that is considered probable. For example a speculation that all crows are black and each time a new crow is observed and found out that its black the assumption is increasingly confirmed. On the other hand if the crow is found not to be black then the assumption's found to be false..

Why must organisms of the estuary be adapted to varying levels of salinity? A.Fresh river water flows into the estuary
B.Saline ocean water flows into the estuary
C.Ocean tides increase and decrease the amount of ocean water
D.All of the above
Organisms in estuaries must adapt to varying levels of salinity due to the unique environment where fresh river water and saline ocean water meet, creating varying and changing salinity levels. Fresh river water, saline ocean water, and ocean tides all contribute to these salinity changes.So, the correct answer is D. All of the above.
Explanation:Organisms in the estuary must be adapted to varying levels of salinity because of the unique factors of their environment. The estuary is a transitional zone where fresh river water meets marine or saline ocean water. This creates varying levels of salinity, which can even change with the tides. Therefore, organisms living there have to adapt to this ever-changing salinity environment.
This happens because of a combination of the factors mentioned in options A, B, and C. Fresh river water from inland sources flows into the estuary (option A), increasing the freshwater content. On the other hand, saline ocean water also flows in (option B), increasing the salinity. Furthermore, the rise and fall of ocean tides can increase and decrease the amount of saline water entering the estuary (option C). So, the correct answer is D. All of the above.

The weather department in Richmond is forecasting a snowstorm. What is likely to happen to the barometer and thermometer readings in Richmond?
A. Barometer readings will decrease, and thermometer readings will increase.
B. Barometer and thermometer readings will increase.
C. Barometer and thermometer readings will decrease.
D. Barometer readings will increase, and thermometer readings will decrease.
E. Barometer and thermometer readings will not change.
The correct answer is option D. Barometer readings will increase, and thermometer readings will decrease.
The barometers are the devices, which are used for the measurement of the pressure and the thermometer is a device, which is used for the measurement of the temperature. During snowstorm, the temperate is decreased and the pressure is high. So, the reading on the thermometer would decreased, and the reading on the barometer would be increased.
