Answer:
here.
Explanation:
The genes coding for colour show codominance. Both the brown and white pigment are equally expressed in the phenotype to give the tan colour.
Considering that the allele for brown pigment is CB and that for white pigment is CW, the genotype for the brown bird is CB CB and that for the white bird is CW CW.
Crossing CB CB × CW CW,
100% CB CW - tan-coloured birds
Rhinoviruses and herpes simplex are just two common viruses out of the other thousands of them that the immune system has to protect the body against.
Given what we know, the three sentences in this question all describe the properties of oceanic crust.
<h3>What is the oceanic crust?</h3>
- The oceanic crust is the outer layer of the earth, located at the bottom of the oceans.
- It contains three layers, ordered by number.
- During subduction, this remains the topmost crust.
- It is formed by the solidification of magma.
- The oceanic crust is known to be very dense.
Therefore, we can confirm that the sentences in the question describe oceanic crust given that this is the topmost crust during subduction, formed by the solidifying of magma, making it a much denser rock than the other forms of crust.

Answer:
92 molecules
Explanation:
DNA or Deoxyribosenucleic acid is polynucleotide made up of several nucleotides containing the genetic information of an organism. In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA, tightly coiled many times around proteins called histones to support its stucture.
Human cells, like myself, contains 23 pairs of chromosomes (46 chromosomes in total). Each pair coming from each parent. Each chromosome is formed by two strands of DNA held together by hydrogen bonds forming the DNA double-helical structure. These two DNA strands form a base pair, which is a unit of two nucleotide bases bound to each other by hydrogen bonds. According to the complementary base pairing rule, Adenine (A) pairs with Thymine (T) while Guanine pairs with Cytosine (C).
Since there are 46 chromosomes in a diploid human cell and each chromosome consists of 2 DNA strands, then, there are 46 × 2 = 92 strands/molecules of DNA in each human diploid cell.
