I need a picture in order for me to answer your question
The normal human karyotypes contain 22 pairs of autosomal chromosomes and one pair of sex chromosomes.
Therefore the best answer choice is:
<span>B. 1 pair of sex chromosomes and 22 pairs of autosomal chromosomes are pictured.
</span>A karyotype is an organized profile of a person's chromosomes. Two chromosomes specify sex, XX for female and XY for male. The rest are arranged in<span> pairs, numbered 1 through 22, from largest to smallest.</span>
The answer is B proteins.
Explanation:
In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them.
Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number.
Reduction is the gain of electrons by a specie. It leads to a lower oxidation number.
Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work.
Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond.
- Between two atoms bonded covalently, the more electronegative specie draws the electrons closer.
- This leaves a partial negative charge on it.
- The other electron then becomes partially positively charged.
- We can then say, the more electronegative specie undergoes reduction.
- The less electronegative one undergoes oxidation.
