Answer:
hmm..unethical i would say..
Explanation:
The base found in RNA nucleotides, but not in DNA, is uracil.
RNA and DNA share three bases: adenine, cytosine, and guanine. However, for the fourth base, DNA has thymine while RNA
has uracil. When forming base pairs, cytosine bases are matched with guanine, while adenine bases are matched with uracil or thymine.
Explanation:
it shrinks due to the low moisture content
Answer:
D
Explanation:
Sample D will undergo the fastest rate when subjected to chemical weathering.
What is weathering?
- It is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
- Physical weathering is also known as mechanical weathering. It entails breaking rocks into smaller sized chunks.
- Chemical weathering is the decomposition of rocks by chemical action.
From the given choices, option D will have the largest surface area exposed to chemical actions. It has more surface area compared to the others. The more broken a mass is, the more its surface area is.
Reaction rates are affected by:
- Increase in surface area
- Increase in temperature
- Higher concentration
- Increase in pressure
The last cube has the highest surface area and will have the fastest rate of weathering.
The hormone being referred to is Epinephrine.
This hormone is secreted mainly in the medulla of the adrenal glands and it functions primarily to increase cardiac output and to raise glucose levels in blood. Normally the hormone is produced during acute stress, and its stimulatory effects fortify and prepare individual for fight or flight.
