Answer: Carbon-14

Explanation:

Carbon dating the procedure which is used for the substances which is used to date the substances less than 40,000.

This method is based on an unstable isotope of carbon that living animals and plants incorporate inside it.

When the organisms are alive the ratio of stable isotope inside the organism is same to the ratio that is found in the atmosphere.

As the organism dies the carbon 14 gets converted into nitrogen 14. By measuring both the ratios, the relative age can be determined.

Explain why Balcetis and her team came up with the slogan, "Keep your eyes on the prize."
Lesechka [4]

Answer:

Balcetis explains that when people are in shape, they are more likely to view an exercise as achievable. More important than fitness, however, was individuals’ motivation to exercise. Those who were motivated to exercise saw a finish line as closer, than those who were unmotivated.

In a second study, Balcetis experimented with how changing one’s perspective on an exercise, can help to make it seem more doable. Balcetis presented a finish line at the end of a moderate sized path. Her control group looked around their settings as they normally would, and then estimated how far away the finish line was. The experimental group was instructed to look directly at the finish line and to try to eliminate other objects in their point of view. The results: the group that kept their eyes on the prize estimated the finish line to be thirty percent closer than those in the control group.

Last, Balcetis examined how perspective can help directly improve ease and efficiency. She had subjects try a moderately difficult exercise of walking a fair distance with weights. Again, one group kept their eyes on the finish line, while the other group proceeded normally. Those who focused on the finish line, felt that the exercise was fifteen percent easier than those in the control group. The focused group also moved twenty-three percent faster.

So what do all these findings mean? The way we look at exercise can make a big difference in how hard it feels and how hard we work at it. As Balcetis says, “keeping your eyes on the prize, may be an additional strategy you can use to promote a healthy lifestyle.” Well any strategy that makes exercise seem easier and gets me working harder, is one I’m definitely down for.

--> Yogurt

Explanation:

Vegetarians are individuals that involves in a dietary practice whereby they avoid some foods such as meat and by products of meat. This is practised by these individuals either due to the health benefits or for some religious beliefs.

--> partial vegetarians and

--> lacto Ovo vegetarians.

LACTO OVO VEGETARIANS are those vegetarians that exclude meat, poultry, and fish but take plant-based foods, dairy products, and eggs. They can obtain vitamin B-12 from hard boiled eggs and yogurts. This is so because, Vitamin B12 is naturally found only in animal foods such as meat, fish, seafood, poultry, eggs, milk, yogurt and cheese. Since the lacto ovo vegetarians do not feed on meat, fish or seafood, the potential sources of vitamin B-12 for a person who follows a lactoovovegetarian dietary pattern are hard boiled egg and dairy products such as yogurt

What happens at a cellular level during organ rejection?
Aleks04 [339]

Organ rejection takes place when your body is subjected to a new organ which is a foreign object and attacks it.

<h3>What do you mean by Graft rejection?</h3>

Graft rejection may be defined as a process in which a transplant recipient's immune system attacks the transplanted organ or tissue.

Xenograft shows high rejection. This is because it involves the transplantation between genetically distinct members of different species.

The process of organ rejection is initiated by T cells which perform the role of the recognization of a transplanted organ.

If these T cells are activated, it may lead to organ rejection by undergoing clonal expansion, and differentiation of the effector cells, which together lead to the obliteration of the tissues.

Therefore, organ rejection takes place when your body is subjected to a new organ which is a foreign object, and attacks it.
