radium in an element found in group 2 and period 7. in a normal radium atom, how many energy levels contain at least one atom?
A. 1 B.6 C.7 D.8
Answer:
the answer is d
Explanation:
In a normal radium atom, there are 7 energy levels.
The periodic table is arranged in groups and periods. The elements in a group have the same number of valence electrons while the elements in the same period have the same number of energy levels.
Radium is an element in period 7. The fact that it is in period 7 implies that it has 7 shells or energy levels. Hence, in a normal radium atom, there are 7 energy levels, each containing electrons.

Explain an example of how artificial selection can help solve human problems.
Answer:
Artificial selection can help solve human problems since humans can choose the desired traits of an organism to coordinate with their needs.
Explanation:
Since artificial selection is predictable, it is easier for humans to "customize" the traits of an organism to get a desired trait.

If two air masses have the same relative humidity of 60 %, which one contains more water vapor?
a. The one with the higher temperature
b. Both would have the same amount
c. The one with higher relative humidity
d. The one with the lower temperature
b. Both would have the same amount
Option b. Both contain a similar amount.
Given that,
The two masses should have a similar relative humidity of 60%.We need to find out which have more water vapor.Based on the above information, we can say that since both two masses contain the same humidity i.e. 60% so it means that they have the same amount.
Therefore the option b is correct.

In snapdragon the gene that affects flower color has two alleles: red (R) and white (W). In heterozygous individuals, the phenotype is pink. If two pink flowers were crossed what would be the probability of a pink offspring?
A. 25%
B. 50%
C. 75%
D. 100%
Answer:
The correct answer is - 50%
Explanation:
In the heterozygous condition, there is always one allele of dominant and one allele of recessive present together and during gamete formation, they assort independently. The probability of the pink flower that is RW can be found by punnet square:
R W
R RR RW
W RW WW
here, out of four two cases is of heterozygous or pink flower so the ration would be 2/4 or 1/2 or 50%
Which organism is defined as something that lives deep in the ocean in areas with very high temperatures and pressure?
Answer:
shark
Explanation:
Organisms living in the deep ocean must be adapted to survive under extreme pressure, limited light, cold temperatures, and other factors. Organisms living in the deep ocean must survive in a physical environment that is radically different from ocean habitats near the sea surface.
What type of pressure system usually brings cloudy, stormy, or 'lousy'
weather?
Answer:
Low Pressure System
Explanation:
Low Pressure System is a region where the atmospheric pressure is lower than that of surrounding locations.
Low pressure because that sucks the surrounding air in creating a "mushroom cloud" of air and water vapour. This then cools and condenses creating clouds and rain.
What agent of deposition is this? Gravity,wind, waves, running water or glaciers.

How many atoms of carbon, hydrogen, and oxygen are there in the reactants of photosynthesis?
Answer:
The reactants have one carbon atom, four hydrogen atoms, and four oxygen atoms. IN HYDROGEN ATOMS It takes six atoms of carbon (C) and twelve atoms of hydrogen (H) to make one molecule of glucose (C6H12O6). These atoms come from carbon dioxide (CO2) and water (H2O). IN OXGYEN It takes six atoms of carbon (C), six atoms of oxygen (O) and twelve atoms of hydrogen (H) to make one molecule of glucose (C6H12O6).
In photosynthesis, the reactants have one carbon atom, four hydrogen atoms, and four oxygen atoms.
What do you mean by photosynthesis?Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants. After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
