The analysis of a DNA molecule reveals that 30% of its nucleotides are adenine. What percentage of the same DNA molecule would b
Contact [7]

Answer: 20%

Explanation:

Recall that the sum of all nitrogenous bases is equal to 100%.

Hence: A + C + G + T = 100%

Now, since adenine nucleotides is 30%, then thymine is 30% as well (A = T). Thus, the total of both is 60%.

From 100 remains 40% which is divided equally between guanine and cytosine, so each is 20%.

Thus, the percentage of the same DNA molecule that would be expected to be guanine nucleotides is 20%

Answer:

evaporation, condensation, and precipitation.  Evaporation is the process of a liquid's surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor. condensation water which collects as droplets on a cold surface when humid air is in contact with it. Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain. properties of ocean water.Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity. The two basic types of currents – surface and deep-water currents – help define the character and flow of ocean waters across the planet.On the landscape, freshwater is stored in rivers, lakes, reservoirs, and creeks and streams. Most of the water people use everyday comes from these sources of water on the land surface. Lakes are valuable natural resources, both for human and non-human life.

Select the reasons that farmers typically only specialize in one breed.
Bogdan [553]
Answer options are
✅Homogeneous housing -
✅Familiarity with the breed
✅Business efficiency
✅Standardized food supply
Lack of training ❌
Time demands❌
✅Personal preference

Reasons
I’m using beef cattle to determine these answers.

I chose the ✅ answers because of the following
✅ Homogenous housing. If you live in extremely cold or hot climates, you want livestock that can withstand cold temperatures for housing reasons. Hereford and Angus are hearty and survive cold temps, Brahman are warm weather cattle.

✅Being familiar with the breed makes raising that breed easier. For example if you know Angus beef cattle and not Chalais dairy cows, you won’t know the Chalais’s unique characteristics.
✅Business efficiency - having one brand or one breed in this instance will save in time, management, food supply, medicines, etc. Different breeds will require different nutrients and feed, different housing requirements, for example.
✅ Standardized food supply. Again, different breeds require different nutrients. Having just one breed will keep food supply simple.
✅ personal preference. Although this might not be a sound business practice, people tend to stick with things they know and like.
