Answer: A forensic palynologist can help a crime investigation because they can examine the pollen in the victim and compare it with the pollen from the suspects by using a comparison microscope to tell if it's a match.
Answer: Well, forensics is the study of the application of science to criminal and civil laws, mainly—on the criminal side—during criminal investigation. So they have an important role in the judicial system because they study criminal reports and files, Identify and classify crime scene evidence through scientific analysis, and then they have to explore possible links between suspects and criminal activity using the results of chemical and physical analyses. So in a crime scene, they might examine the details that they might notice, like the position of the victim or the objects surrounding the scene, test and analyze them, and then follow the leads they get from that.

When two pink flowers (RW) are crossed, there are four equally likely possible outcomes for the genetic makeup of the offspring: red (RR), pink(RW), pink(WR), and white (WW). If two pink snapdragons are crossed, what is the probability that the offspring will be (a) pink, (b) red, and (c) white?
Answer:
a) 50% chance of being pink
b) 25% chance of being red
c) 25% change of being white
Explanation:
Since neither the R allele or W allele is dominant over the other, this is codominance. If 2 pink ones are crossed, that means both of them are RW
If we draw out the punnet square
R W
R RR RW
W RW WW
There is a 1:2:1 ratio of Red to Pink to White
Therefore
a) 50% chance of being pink
b) 25% chance of being red
c) 25% change of being white
A woman with type A blood (whose father was type O) has children with a man that has type O blood. Both individuals are heterozygous for the MN antigen. Recall that MN blood group antigens are independent of the ABO locus, and that the alleles are codominant.
How would the results from Part A change if both parents are also heterozygous for the FUT1 gene controlling the synthesis of the H substance (Hh)?

Type O with M and N antigens:__________.
Type O with antigen:_________.
Options: 0, 1/32, 3/32, 5/32, 6/32, 10/32, 1
Answer:
Explanation:
A woman with type A blood (whose father was type O) meaning her genotype is AO mates with
Man that has type O blood (OO genotype)
Both are heterozygous for MN blood group and both also heterozygous for the FUT1 gene controlling the synthesis of the H substance (Hh)- which determines the expression of the A and B antigen.
Cross
A O M N H h
O AO OO M MM MN H HH Hh
O AO OO N MN NN h Hh hh
Type A- 1/2 O-1/2 type M- 1/4 MN-1/2 N- 1/4, type H- 3/4 h-1/4
Type A with M antigen:
1/2*1/4*3/4 = 3/32
Type A with M and N antigens:
1/2*1/2*3/4 = 3/16
Type A with N antigen:
1/2*1/4*3/4 = 3/32
Type O with M antigen:
1/2*1/4*3/4= 3/32
Type O with M and N antigens:
1/2*1/2*3/4 = 3/16
Type O with N antigen:
1/2*1/4*3/4 = 3/32.
The 3/4 value comes from the expression of Hh-3/4 (this determines if the A and B Angie will be expressed).

2)Masses of matter collide, masses of matter form around dust grain, and atoms and molecules are added to dust grain.
3)Atoms and molecules are added to dust grain, masses of matter form around dust grain, and masses of matter collide.
4)Masses of matter collide, atoms and molecules are added to dust grain, and masses of matter form around dust grain.
Answer:
The correct option is 3. Atoms and molecules are added to dust grain, masses of matter form around dust grain, and masses of matter collide.
Explanation:
Two theories explain how planets get formed. One of them is The gravitational instability, and the other one is the Planetesimal Hypothesis.
The planetesimal hypothesis says that a planet formation is a process in which dust particles and gas collide and get stick together in a process known as coagulation. This makes place to grains production. These grains enhance their sizes up to a point in which they form bodies big enough to be called planetesimals. When planetesimals are formed, they start a gravitative interaction with other planetesimals of different sizes, and by collision, they form bigger planetesimals that accrete the smaller ones and end up forming a proto-planet. Planets and giant planets get formed by accretion of solid planetesimals. The term accretion refers to the solids agglomeration to form bigger objects, such as planets.

Identify the correct statements about transcription(Tnx) and (Tnl) translation in prokaryotes and eukaryotes.
A. Prokaryotes conduct Tnx and Tnl together in the same cellular compartment.
B. Eukaryotes do Tnx in the nucleus and Tnl in the cytoplasm.
C. Tnx and Tnl occur together in the cytoplasm of Prokaryotes and Eukaryotes.
D. Tnx and Tnl both occur in the nucleus in eukaryotes and prokaryotes.
Answer:
A and B
Explanation:
The correct statements about transcription and translation would be that prokaryotes conduct transcription and translation together in the same cellular compartment and eukaryotes do transcription in the nucleus and translation in the cytoplasm.
Prokaryotes generally lack a nucleus and other membrane-bound organelles and as such, their genetic materials lie freely within the cytoplasm. Hence, transcription and translation take place within the same cellular compartment, which is the cytoplasm.
Eukaryotes, however, have a nucleus and other membrane-bound organelles such as mitochondrion. Their genetic materials lie majorly in the nucleus. Hence, transcription takes place within the nucleus. Thereafter, the transcribed mRNA is transported to the cytoplasm where they get attached to ribosome and tRNA and translated into proteins.
The correct options are A and B.

11. vascular cambium
Both:
8. occurs in plants that live many years
Explanation:
Plant primary growth starts with successive cell division cycles in undifferentiated cells that form the shoot apical meristem, thereby lengthening roots and stems. The meristems represent a type of tissue involved both in primary and secondary growth. Herbaceous plants have only primary growth and grow in length.
Secondary growth is caused by the growth of the vascular cambium (cambia) and lateral meristems. It is characterized by an increase in thickness of stems and roots. Vascular plants (i.e., plants with a xylem and phloem system) have secondary growth.
In woody plants, the primary and the secondary growth patterns occur across years, and thus they can increase their length (primary tissue growth) and diameter (secondary tissue growth).
