Answer:

Explanation:
In the given question, the anthropologist when examines the left and right arm he found that the left arm is thicker than the right arm.
The more thickness of the left arm signifies that the person uses his left arm for the muscular work as the more use of hand increases the deposition of the calcium phosphate and sulfate in bones along with other material which increases the thickness for the bones and increases the strength.

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.
