Answer:</u></em></h2>
The five steps that are always taken in scientific research are;
- establishing a hypothesis
- doing research and assembling data
- and finally proceeding to a conclusion
<h2><em><u>
Explanation:</u></em></h2>
- Arya already performs the first two steps; as she first recognize the problem i.e. she observes the dry glass and she also formulate a hypothesis that "the water content in the soil is about two-thirds lower than that of other yards in the area"
- Now she will collect the data and conduct the experiment on the soil and glass and then she will assemble the conclusion based on the results.Now she will collect the data and conduct the experiment on the soil and glass and then she will assemble the conclusion based on the results.
Answer:
HbA; lowers
Explanation:
The BPG in our blood stands for Bisphosphoglyceric acid. It is known as by its name as 2,3-Bisphosphoglyceric acid. It is present in our blood in the red blood cells. It binds with more affinity towards the de-oxygenated hemoglobin as compared to the oxygenated hemoglobin.
Hemoglobin in blood delivers oxygen to our tissues moire efficiently. It is abbreviated as Hb.
Thus BPG binds more tightly towards HbA or adult hemoblobin and which lowers the affinity for oxygen.
<h3>
Answer: E) carbon of the carboxyl group and the nitrogen of the amino group.</h3>
Explanation:
tyrosine and isoleucine are amino acids.
When they are condensed, they form a peptide bond which occurs between the carbon of the carboxyl group and the nitrogen of the amino group (OPTION E).

Answer:
F,T,T,F
Explanation:
1)false-(its a covalent bond)
A water molecule is formed when two atoms of hydrogen bond covalently with an atom of oxygen.
2)True-(water is a polar molecule)
Water is a polar molecule because the positive end attracts particles of negative charge.
3)True
water dissociates to form hydrogen ions (H3O+) and hydroxide (OH-) ions
4)false
Lower pH number means stronger acid, higher pH number means stronger base.
