Answer:
brown hair and physical trait
A DNA molecule consists of two stands of nucleotides that wind around each other like a twisted ladder with a phosphate and sugar backbone. The nitrogenous bases are divided into two groups called the pyrimidines and the purines. The pyrimidines include the thymine and cytosine, the purines are adenine and guanine. The nitrogenous bases in the double helix are bound together according to the base pairing rule. Adenine pairs with thymine (A-T) and guanine pairs with cytosine (G-C). The student either drew the base pairing showing adenine and thymine or guanine pairing with cytosine.
The statement which is false about the intergumentary system is option D. "Keratin is the pigment responsible for skin color."
Even though the skin color of human beings is affected y different substances, the pigment melanin is responsible for it. Melanin is produced within the skin in cells known as melanocytes and it determines of the skin color of darker-skinned humans.
For instance, the skin color of those who have light skin is determined primary by the bluish-white connective tissue placed beneath the dermis and by the hemoglobin which circulates in the veins of the dermis.
After cytokinesis is completed, the cell enters into G1 Phase.
<h3><u>Answer;</u></h3>
<em>A. continental-oceanic convergent</em>
<h3><u>Explanation;</u></h3>
- <em><u>A convergent boundary</u></em> is a type of boundary where two plates collide and push against one another.
- <em><u>A continental-oceanic convergent</u></em> is a type of convergent boundary that occurs as a result of <em><u>subduction.</u></em> <em><u>Subduction occurs where a continental plate collide thus resulting to the oceanic plate being pushed underneath the continental plate</u></em> into the mantle since the oceanic plates are much thinner.
- The result is that <em><u>the oceanic plates melts into hot magma which that burns its way up through the continental plate</u></em> forming a volcano and also causing earth quakes.
