How many NEUTRONS does an element have if it’s atomic number is 44 and it’s mass number is 154 ?

1 answer:

6 0

If the element has a atomic number of forty-four then the amount of neutrons would be "fifty-seven." This element is actually called Ruthenium and it has forty-four protons, and electrons, and it has fifty-seven neutrons and you can determine this by using this equation then solve:

$44 + N = 101$

$= 57$

Hope this helps!

An experiment was designed to investigate if caffeine would raise the heartbeat of water fleas. Two groups of water fleas were u

fgiga [73]

Answer:

That is administered and controlled

Step-by-step explanation:

A variable is the condition or a product that may vary without the influence of any investigator. Such variables can be found abundantly in our daily lives, ranging from air to sunlight. Controlling such variables ensures the limitation of their influence on the outcome of an experiment. In connection to this experiment, the variables that are controlled are the mineral content in the water, the amount of bacteria food, the amount of light and the the constant temperature of 20 degrees C.

If not administered or these variables controlled, the experiment would not clearly explain the impact of caffeine on the heart beat of the water fleas as other variables may have influenced it. Thus variables are controlled to study the singular impact of any agent or effect.

Three linked autosomal loci were studied in cucumbers: fruit color (dark vs. light), tendril size (long vs. reduced) and fruitin

Zina [86]

Answer:

Explanation:

1. Progeny observed in the experiment is calculated by adding all the progeny numbers observed in the :

TIME TO FRUIT TENDRIL SIZE FRUIT COLOR NUMBER

Normal normal dark 370

normal normal light 32

early normal light 971

early normal dark 28

early reduced dark 25

early reduced light 483

normal reduced light 36

normal reduced dark 810

TOTAL

PROGENCY 2755

2. The locus in the center is TIME TO FRUIT. Tendril size is at the beginning of the locus and the distance between the locus B and locus C is R2
