How can accidental transfer of DNA impact a crime scene investigation? In addition, explain why accidental DNA transfer cannot be used as an excuse to throw away all DNA evidence found at a crime scene?

Answers

Answer 1

Answer:

orensically valuable DNA can be found on evidence that is decades old. However, several factors can affect the DNA left at a crime scene, including environmental factors (e.g., heat, sunlight, moisture, bacteria, and mold). Therefore, not all DNA evidence will result in a usable DNA profile.

If each parent has two sets of genes and chromosomes why do their offspring receive only one set from each parent

Answers

Answer:

Because we are diploid humans, and we have 2 chromosomes per set. We get one set from our mother, and one from out father. Each of the sets from our parents are haploid (1 ), so together they are a diploid(2) set. I can go into depth more with meiosis if you need.

some scientists predict that if global warming continues over the next few centuries, melting of the polar ice caps will rise the level of the oceans causing some peninsulas to become islands. how might this change eventually affect the species that live on these peninsulas?

Answers

Answer:

As global warming causes more snow and ice to melt each summer, the ocean and land that were underneath the ice are exposed at the Earth's surface. Because they are darker in color, the ocean and land absorb more incoming solar radiation, and then release the heat to the atmosphere.

What are the three layers that make up the body of a Cnidarian?

A. endoderm, mesoderm, ectoderm
B. endoderm, mesoglea, ectoderm
C. ectoderm, mesoderm, mesoglea
D. endoderm, mesoglea, epidermis

Answers

The endoderm is the inner layer ('endo' for 'within'), and the ectoderm is the outer layer ('ecto' for 'outer'). If there was a third layer it would be called the mesoderm, 'meso' for 'middle'. But cnidarians do not have this middle layer. Germ layers develop during gastrulation.

Answer:

endoderm, mesoglea, ectoderm
