This is a dna fingerprint exhibiting samples from a victim, two suspects, and the crime scene. which of these dna fragments is common to both the victim and suspect 1? question #9 this is a dna fingerprint exhibiting samples from a victim, two suspects, and the crime scene. which of these dna fragments is common to both the victim and suspect 1? question #9 a b c d e
The question shows the results of a gel electrophoresis, which shows DNA fragments of the victim and two suspects, suspect 1 and suspect 2. A comparison of the five DNA fragments of the victim, A to E, reveals that the victim and suspect 1 both have the DNA fragment b.
A
visual comparison of the gel electrophoresis results should reveal that Suspect
1 has a DNA fragment that matches victim DNA fragment B.The visuals can be seen in the attachment.
Without a visual reference, it's not definitive to say which DNA fragment is common between the victim and suspect 1. However, in DNA fingerprinting, common fragments are visible as aligned bands in the same position in both samples.
Explanation:The process of identifying the DNA fragments in a sample is known as DNA fingerprinting. Without an image or graphical representation of the DNA fragments from the question, it's impossible to definitively say which fragments are common between the victim and suspect 1. However, in a typical DNA fingerprinting procedure, common fragments would be represented as bands in the same position in both the victim's and suspect 1's DNA samples.
This procedure is based on the concept of gene loci where each individual has unique DNA sequences. The comparison, in this case, is done by looking at the bands' positioning in each sample. If multiple bands, or even a single significant band, aligns between the victim and suspect 1, there could be a link suggesting that suspect 1 might be related to the crime scene.

Difference between unicellular and multicellular.
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialised it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level. Unicellular organism has simple body organization and multicellular organism have complex body organism.

Describe the short term and long term process of the carbon cycle
The short-term is of the carbon cycle is interactions between the terrestrial and marine components of the biosphere and the atmosphere. The long-term of the carbon cycle is the formation and destruction of fossil fuels and sediments containing organic carbon.
What is a carbon cycle?The carbon cycle is nature's method of recycling carbon atoms, which repeatedly go from the atmosphere into Earth's living things and back into it.
The majority of carbon is kept in rocks and sediments; the remainder is kept in the ocean, atmosphere, and living things. The carbon cycle is the regulation of carbon from one form to another.
Thus, the short and long terms of the carbon cycle are the formation of natural components by the means of the natural processes with the presence of carbon.

Why does the sympathetic division of the ans have a more generalized effect in the body?
a. one preganglionic neuron synapses with many postganglionic neurons
b. one preganglionic neuron synapses with one or two postganglionic neurons
c. the secretion of epinephrine and norepinephrine can effect many organs
d. both choices a and c are correct?
The right answer is D.
The sympathetic nervous system is one of the three components of the autonomic nervous system, managing the activity of visceral organs and the automatic functions of the body, such as breathing or beating of the heart. The sympathetic nervous system is involved in many unconscious physiological activities through two neuromodulators of the catecholamine family: adrenaline, but especially norepinephrine.
At the level of the sympathetic nervous system:
* A pre-ganglionary neuron innervates approximately twenty ganglionic neurons
* A ganglionic neuron innervates several effectors (multiple organs)
This difference in axon branching explains in part the differences in the extent of the effects of sympathetic and parasympathetic systems.

-It catalyzes a series of reactions.
-It breaks down immediately following the reaction it catalyzes.
-It changes the amount of energy released at the end of a reaction.
-It binds a single set of substrates,
it binds a single set of substrates
An enzyme is a protein that functions as a catalyst, accelerating a biochemical reaction without being consumed by the reaction. It can work on many substrates, not just one, and can be reused repeatedly.
Explanation:The molecule under discussion, an enzyme, is a type of protein that acts as a catalyst to speed up a specific biochemical reaction within a cell. The options provided include four functions, but the one that best characterizes an enzyme is that 'It catalyzes a series of reactions'.
Enzymes don't break down immediately following a reaction. Instead, they can be reused for the same reaction repeatedly, and they don't change the amount of energy released at the end of a reaction. They do, however, lower the activation energy required for a reaction to occur, thus speeding up the process. Also, while enzymes do bind to specific molecules (substrates), they are not limited to a single set of substrates and can interact with various molecules.

A population is a population is a group of individuals of the same species that live in the same area and interbreed. all individuals of a species, regardless of location or time period in which they live. a group of individuals of different species living in the same place at the same time. a group of individuals of a species plus all of the other species with which they interact.
A population refers to a group of organisms of the same species, living, interacting, and interbreeding within a certain geographic area.
A population is a term used to describe a group of organisms of the same species that are living in the same area and interacting with each other. This can include aspects such as their demography or genetics. In population ecology, scientists are interested in studying various features of how these populations live, such as density, dispersion, and birth and death rates, which help determine the health and stability of the population.
To further illustrate, all of the angelfish living in the same area of the ocean constitute the angelfish population. These populations not only live in the same geographic area but also interbreed, which means they share a gene pool. The gene pool consists of all the genes found among the individuals in that population, which is important for the survival and adaptability of the species.
Populations are identified partly by where they live. Their area of population may have natural boundaries like rivers and mountains, or artificial ones like roads or manmade structures. These boundaries define the geographic area considered the habitat within which populations interact and undergo processes like competition and cooperation.

Why doesn't dr. logan feel the bed bug feeding on him? why doesn't dr. logan feel the bed bug feeding on him? the bed bug has very soft feet and mouthparts. the bed bug is tiny and weighs very little. the bed bug doesn't actually bite, but feeds by osmosis. the bed bug injects an anesthetic as it feeds. submitrequest answer?
The answer is the bed bug injects an anesthetic as it feeds.
Bed bugs are tiny blood sucking insects that have an exoskeleton. These insects are found in places like the edges of the bed, cavities, etc. where they hide in the day time. During night, these insects come out and bite their hosts to feed on the blood. However like Dr. Logan, no one feels the pain due to the bite because the bed bugs also inject an anesthetic to avoid the host from detecting their presence. Anesthetic is a drug substance that stops the pain receptors from signalling the brain about the pain.
At a laboratory at case western reserve university in 1998, geneticist patricia hunt was making a routine check of her female lab mice. as she extracted and examined developing eggs from the ovaries, she began to wonder what had gone wrong. she noticed that many of the eggs showed problems with their chromosomes, and some had irregular amounts of genetic material, which can lead to miscarriages and birth defects in mammals. she learned that a lab assistant had mistakenly washed the plastic mouse cages and water bottles with a harsh soap, releasing bpa from the plastic. knowing that bpa is an endocrine disruptor, a chemical that can enter organisms and mimic hormones, hunt set out to discover whether it had adversely affected her mice.
Bisphenol A (BPA) is an endocrine disruptor that has been linked to multiple health issues, especially during developmental periods. Research indicates that even at low levels, BPA can disrupt hormonal balance and gene expression, with the FDA encouraging reduced use in food-related materials.
Explanation:The research done by Patricia Hunt and subsequent studies have highlighted the potentially harmful effects of an endocrine disruptor known as bisphenol A (BPA). BPA exposure can lead to a series of health problems like developmental delays and an increased risk of cancers. These health risks are particularly concerning during the prenatal and postnatal periods. Additionally, the endocrine system's regulation can be significantly interfered with by BPA, which mimics hormones such as estrogen or has the opposite effect of androgens. The U.S. Food and Drug Administration (FDA) has facilitated the decreased use of BPA in food-related materials and many manufacturers have voluntarily removed BPA from products, particularly those for babies.
In experimental studies, both in vivo and in vitro, BPA has been observed to cause changes in gene expression leading to various health outcomes. Exposure to BPA has also been implicated in epigenetic inheritance, where environmental factors can influence gene expression in subsequent generations. In light of these insights, it's suggested that risk assessments for toxic substances, especially those that can act as endocrine disruptors, need a more nuanced approach that considers low-level exposure effects over prolonged periods.
