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 three independent variables in these experiments
Answer: A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist.

Un organismo con un caracter genotípico heterocigote presentará, excepto A Alelos iguales B una linea híbrida C alelos diferentes D una linea pura E a y d
Answer:
C alelos diferentes.
Explanation:
Los alelos son las distintas formas en las que un gen puede ser expresado. Cuando un gen es dialélico implica que puede haber dos formas diferentes del mismo gen, una dominante y otra recesiva. Estos alelos serán heredados de la línea parental en la que un progenitor aporta un alelo y el otro progenitor aporta otro alelo, que se combinaran durante la formación del cigoto. La combinación de alelos de un mismo gen en un organismo determina la forma en la que determinada característica será expresada en el individuo.
• Cuando dos alelos iguales se combinan en un organismo, se habla de un genotipo homocigota. Estos alelos pueden ser los dos dominantes o los dos recesivos.
• Cuando se combina un alelo dominante con uno recesivo, se habla de genotipos heterocigotos. El individuo que posea un genotipo heterocigota, portará ambos alelos pero expresará el fenotipo del alelo dominante.

FOR THE SECOND TIME-----Ughhh can someone answer this dang biology question I cant!!!!! I will mark you brainliest!!Referring to the graph, what phases together would account for approximately 25% of the time spent from a cell in the cell cycle?
A) M phase and S phase
B) S phase and M phase
C) G1 phase and M phase
D) G2 phase and M phase
Answer:
D. G2 phase and M phase
Explanation:
If we are looking for what takes up 25% of the graph, that would be the last option. If you look at G1, it takes up about 50%. So, G1 phase and M phase would take up more than that, and we want 25% not 50+. The M phase and S phase would take up about a third, so no. The G2 phase and M phase takes up roughly 25% or, it's the closest to this.

Although every zebra has a unique pattern of black and white stripes, the differences are very subtle. The main evolutionary advantage of the stripes is the protection they provide against lions, the main predators of zebras on the African plains. When a zebra herd is packed together, a lion cannot distinguish individual zebras from one another, making it difficult to attack them.
Hi, you've asked an unclear question. However, I inferred you likely need affirmation whether the statement made is true.
Answer:
True
Explanation:
Indeed, zoologists have discovered that stripes on Zebras play an important role in preventing predators from attacking them. It is believed that their unique pattern of black and white stripes acts as a camouflage making them difficult to be spotted by predators.
Despite these findings, scientists are still researching reasons for such observations and they hope to find real-world applications of this natural design.

what is one advantage of having many small cells insted of one larg cell?
Answer:
It's more efficient
Explanation:
Information is transmitted quicker and more efficiently than it would if the cell was larger. It's easier to transport in and out of the cells, making them more efficiently controlled and regulated.

A _________ is a biotic pathogen that lives off its host. A _________ is a biotic multi-celled pathogen that causes infections like ringwor
Answer:
Bacteria
Virus

Fungi
Explanation:
A Bacteria is a single-celled biotic pathogen that is infectious. Bacteria are prokaryotes(single celled) and also form part of the disease causing organisms .
A Virus is an abiotic pathogen that is infectious.
A Parasite is a biotic pathogen that lives off its host. It sometimes uses structures such as hooks to obtain nutrient material from its host.
A Fungi is a biotic multi-celled pathogen that causes infections like ringworm.
In a paramecium, the nucleus divides first and then the cytoplasm divides, forming two identical daughter cells. Which type of reproduction takes place in paramecia?
Answer:
Fission
Explanation:
This form of asexual reproduction is called binary fission. During this, a single parent cell divides and we are left with two daughter cells of equal sizes. Each of these daughter cells can and most likely will grow into the size of the parent cell. This is very common in prokaryotes that usually copy their DNA before dividing.
Answer:
fission
Explanation:

An ecosystem has 150 organisms of 15 different species. What is the biodiversity index of this ecosystem?
Answer:
0.1
Explanation:
To calculate this, scientists use a formula called the biodiversity index in order to describe how much are the species of a given area diverse. It is calculated by taking the number of species in the area and divided by the total number of individuals in that area. This gives us the biodiversity index.
In this example, there are 15 species in an area and we divide that by 150 organisms to get a 0.1 biodiversity index.
Biodiversity Index is used to measure the biodiversity of an ecosystem. The biodiversity index of the given ecosystem is 0.1.
Biodiversity Index:
It is a measure of species diversity in the particular area. This can be calculated by sing the formula,
[tex]\bold{I_b_d = \frac{nS}{nO} }[/tex]
Where,
nS - number of species = 15
nO - total number of organisms = 150
Put the values in the formula,
[tex]\bold{I_b_d = \frac{15}{150} }\\\\\bold{I_b_d =0.1}[/tex]
Therefore, the biodiversity index of the given ecosystem is 0.1.

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.
