Explain why a city that receives 10 hours more light each day has colder average temperatures.
goldenfox [79]

Answer:

Despite the hours of sunlight a city receives, the latitude of the city plays a larger role due to the fact that with a higher latitude, the higher the solar angle allowing a city to be much warmer.

I am Lyosha [343]
Alex is at rock concert. ..................................................... is most accurately called SENSATION. But ................................................. is most accurately called PERCEPTION.
Sensation occurs when light waves enter the sense organs and get converted to electrical impulses. The sense organs involve in this case are the senses of touch, sight, smell, hearing and taste. Perception occurs when the brain send signals to the body which result in identification or recognition of the sensation.

What is the correct order of events: Homologous chromosome separate Chromosome condenses Lining up on metaphase plate, Crossing
Sedbober [7]

Answer:

Chromosome condenses

Pairing up to form tetrad

Crossing over

Lining up on metaphase plate

Homologous chromosome separate

Explanation:

Condensation of chromosomes occurs in prophase I phase. Pairing up to form tetrad occur during prophase I. Crossing over occurs during prophase I of meiosis cell division. Chromosomes line up along the metaphase plate in the stage of Metaphase. Centromeres break down and homologous chromosomes separate in anaphase I phase of meiosis.

HELP ME PLEASE! List the steps scientists for using technology to find the half-life of an isotope.​
liubo4ka [24]

For radioactive materials with short half-lives, you use a very sensitive calibrated detector to measure how many counts per second it is producing. Then using the exact same set up you do the same at a latter time. You use the two readings and the time between them to determine the half-life. You don’t have to wait exactly a half-life, you can do the math with any significant time difference. Also, you don’t need to know the absolute radioactivity, as long as the set up is the same you only need to know fraction by which it changed.

For radioactive materials with long half-lives that won’t work. Instead you approach the problem differently. You precisely measure the mass of a very pure sample of the radioactive material. You can use that to calculate the number of atoms in the sample. Then you put the sample in a counter that is calibrated to determine the absolute number of disintegrations happening in a given time. Now you know how many of them are disintegrating every second. You use the following equations:

Decays per Second = (Number of Atoms) x (Decay Constant)

Half-life = (Natural Log of 2) / (Decay Constant)

And you can calculate the half-life

Hope it helps :)
