Explanation:

7. (True Story) In Denmark, a husband and wife who had been unsuccessfully trying to have a
baby went to a fertility clinic. Sperm and eggs were collected from father and mother, and
combined in a petri dish, creating several "test-tube babies". These babies were implanted in the
mother and 9 months later she ſlelivered twins, one with lightly pigmented skin and one with
darkly pigmented skin. Because this seemed strange, a DNA test was conducted and it was
found that both children were related to the mother, but only the light skinned child was related to
the father. How can this be explained? (Hint, there was no infidelity)

Answers

Answer:a

a possible explanation for this occurrence is that a test tube or dropper was accidentally used repeatedly without being sterilized, causing sample cross-contamination. DNA in this test case did not confirm that the father of the second child was another client of the fertility clinic who had never met the mother...therefore this is a possibility.

The Oceanic Plate is located near the ocean ridge. Which represents where magma creates new oceanic crust.

The Subduction Zone is where the tectonic plates meet.  These are called plate boundaries.  

Convection Currents are what drives the movement of rigid tectonic plates in Earth's molten mantle.

The Asthenosphere is the upper layer of the mantle. Which is below the lithosphere (Continental Plates).  

Continental Plates are the outer shell of the mantle.

Why does DNA need to be replicated

Answers

Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

Answer:

DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!

Explanation:

DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

The replication process relies on the fact that each strand of DNA can serve as a template for duplication. DNA replication initiates at specific points, called origins, where the DNA double helix is unwound. A short segment of RNA, called a primer, is then synthesized and acts as a starting point for new DNA synthesis. An enzyme called DNA polymerase next begins replicating the DNA by matching bases to the original strand. Once synthesis is complete, the RNA primers are replaced with DNA, and any gaps between newly synthesized DNA segments are sealed together with enzymes.

DNA replication is a crucial process; therefore, to ensure that mistakes, or mutations, are not introduced, the cell proofreads the newly synthesized DNA. Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.

Explanation:

Anything that contains atoms emits infrared radiation. Therefore, option (D) is correct.

What is Infrared radiation?

All objects, living or non-living, emit some amount of infrared radiation, which is a type of electromagnetic radiation with wavelengths longer than those of visible light. The amount and wavelength of the infrared radiation emitted by an object depends on its temperature, with hotter objects emitting more and shorter-wavelength infrared radiation.

This is the principle behind the use of infrared cameras and thermal imaging technology to detect and measure heat in a variety of applications, including night vision, medical imaging, and industrial inspections.

Why is the structure of a
nucleosome so important?

Answers

Answer:

In eukaryotes, nucleosomes play major roles in chromatin organization and gene expression  

Explanation:

In eukaryotic organisms, chromosomal DNA is packaged with the help of proteins called 'histones' to form chromatin. The nucleosomes represent the basic packing units of the chromatin. Each nucleosome is composed of a histone octamer containing each two histones H2A, H2B, H3 and H4 wrapped around by 147 bp of DNA. Nucleosomes act as scaffolds to form higher-order chromatin structures (i.e., 30-nm chromatin fibers and condensed chromosomes). Moreover, nucleosome histone proteins can be chemically modified at defined amino acid residues, and thus nucleosomes also provide an epigenetic layer of information that can promote or inhibit gene expression.
