Answer:
Forensic biologist
Explanation:
The specialist needed to find or identify the killer would be a forensic biologist. A forensic biologist uses trace samples or evidence in identifying victims and/or suspects and generally supporting criminal investigations with the aid of scientific techniques. In the case described in the question, there are other samples (aside from body fluids and fingerprints) that can be obtained from the crime scene; for example, in the case of a struggle with the killer, some of the boys could have pulled hair strands from the killer. The root of these hair-strand can be subjected to DNA analysis to identify the killer. There is also the possibility of having one of the boys scratching some skin cells from the killer; these could also be useful in DNA analysis.
The forensic biologist could also determine when and where the actual death of the boys took place, this information could be vital for the law enforcement in predicting where the killer might strike.

What are two things that can pass through a cell membrane which makes it selectively permeable?
Molecules of oxygen and carbon dioxide pass through the membrane via diffusion. However, polar molecules cannot easily pass through the lipid bilayer. They can reach the hydrophobic surface, but can't pass through the lipid layer to the other side of the membrane.

What is equilibrium?
Answer:In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system.
Explanation:
Answer:
Equilibrium means when the concentrations of reactants and products are in an unchanging ratio. Another way of saying this is that a system is in equilibrium when the forward and reverse reactions occur at equal rates.

what characteristic of an element determines its place in the table
Answer:
An element's location in the periodic table is largely dependent on its electrons; the number of valence shell electrons determines its group, and the type of orbital in which the valence electrons lie in determines the element's block.
Explanation:

He stoma is the innermost compartment of a cytoplasm . Here, the Choose... occur(s), breaking down Choose... acid into carbon dioxide in a series of reactions.
Answer:
The matrix is the innermost compartment of a mitochondrion. Here, the Kreb's cycle occur breaking down pyruvic acid into carbon dioxide in a series of reactions.
Note: The question is incomplete. The complete question is given below:
The (matrix / stoma / cytoplasm / nucleolus) is the innermost compartment of a (cytoplasm / cell wall / mitochondrion / nucleus). Here, (glycolysis / the Krebs cycle / fermentation / NAD+) occur(s), breaking down (citric / pyruvic / lactic / nitric) acid into carbon dioxide in a series of reactions.
Explanation:
The mitochondria is a double-membrane bound cell organelle found in the cytoplasm within which the biochemical processes of cellular respiration and energy production occur. Cristae are folds of inner membrane that project into the matrix. The matrix is a gel-like material in the innermost compartment of a mitochondria and is the site for the Kreb's or Citric cycle.
The Kreb's cycle is the third stage of cellular respiration (the first is glycolysis in which a molecule of glucose is broken down into two molecules of pyruvic acid; the second is the preparatory stage which oxidizes two molecules of pyruvic acid to two molecules of acetyl-CoA). In this cycle, the two molecules of acetyl-CoA produced in the preparatory stage is broken down into carbon dioxide in a series of eight energy-extracting reactions producing 2 ATP, 6 NADH, 2 FADH2 and releasing 4 CO2.

compare the number of chromosomes in pumpkins to the number of chromosomes in humans.
PLEASE HELP ASAP!
Answer:
Humans: 46 chromosomes (23 pairs)
Pumpkins: 40 chromosomes (20 pairs)
The number of chromosomes in pumpkins to the number of chromosomes in humans is Humans: 46 chromosomes (23 pairs) and Pumpkins: 40 chromosomes (20 pairs)
What is the number of chromosomes in different animals?If a dog has 78 chromosomes in each of his cells, each set of DNA has two sets of chromosomes because dogs are a diploid species so it would be 78/2 and in each cell a dog with 78 chromosomes would have 39 molecules of DNA in each of his cells.
The final products of meiosis in males is four sperm cells and in females it is one ovum and three polar bodies. Thus, the final product of meiosis is four sperm cell in male and one ovum in female with three polar bodies. The main objective of meiosis is to produce gametes, the sperm and eggs, with half of the genetic character of the parent cell.
Meiosis has been defined as the process in which a single cell divides into two identical daughter cells and the process is known as cell division. Meiosis has a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes.
Therefore, The number of chromosomes in pumpkins to the number of chromosomes in humans is Humans: 46 chromosomes (23 pairs) and Pumpkins: 40 chromosomes (20 pairs)

Explanation:
Natural selection refers to all of the following EXCEPT
Answer:
Darwin proposed the theory of natural selection to explain the process of evolution. According to Darwin’s theory of natural selection, all organisms have the potential to reproduce limitlessly irrespective of the fact that each species maintain a constant density over time. However, the struggle for existence, i.e. the competition among individuals for available resources to survive and reproduce, put a check on species density (D) and maintains it at a constant level (B). Survival of fittest is unequal ability of individuals to survive and reproduce based on suitability of their inherited characters to prevailing environmental conditions (A). It imparts the reproductive advantage to certain organisms which account for major part of the gene pool of the species. Thus, natural selection favors the individual with survival and/or reproductive advantage over others under existing environmental condition (E). Thus, the correct answer is option C.

write down at least 5 examples of dominant, recessive or co dominant alleles and what their crosses would yield
Answer:
If both alleles are dominant, it is called codominance. The resulting characteristic is due to both alleles being expressed equally. An example of this is the blood group AB which is the result of codominance of the A rose comb is produced when at least one dominant allele is present at the first locus and two recessive alleles are present at the second locus (genotype R_ pp). A pea comb is produced when two recessive alleles are present at the first locus and at least one dominant Dominant and Recessive Traits List 1． Widow’s Peak. Also known as mid-digital, hairline is a result of expression of the hairline gene.

How does static electricity work?
Answer:
"Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. One way to discharge them is through a circuit. ... Remember, objects with the same charge repel each other." ~ www.loc.gov
Essentially saying that if you have a lot of friction, it will create a positive and negative electric charge, this electric charge also contains a small magnetic field which is static electricity.
