An investigator conduct laboratory tests on unburned control material collected from a fire scene to analyze the breakdown products A gas chromatograph is most often used to detect and characterize recovered flammable residues.
Laboratory tests, Analyses of the breakdown products produced by the material's exposure to intense heat during the fire can be performed in the laboratory on unburned control material. Analytical chemistry commonly employs gas chromatography for the separation and analysis of compounds that can be vaporized without decomposition.
The gas chromatograph is the most delicate and solid instrument for distinguishing and portraying combustible buildups. Accelerants like gasoline and kerosene are what start the majority of arsons.

An astronaut is planning a trip to a newly-discovered planet according to the law of universal gravitation, the astronaut weight in the new planet will be greater than his weight on earth if:
Answers
The new planet has more mass than Earth but the same radius. The mass of the astronaut will be calculated by the use of Newton's gravitational equation. The weight of the astronaut depends completely on its mass and the gravitational acceleration of the planet.
Gravitational acceleration is directly proportional to the mass of the planet and indirectly proportional to the radius of the planet. Hence, when the gravitational acceleration increases the planet's mass will increase therefore the radius will decrease. The astronaut's mass will depend on these factors.

1. Identify the input and output
for an washing machine.
2. Identify the organ-system components, and the input
and output, and describe the operation of the biological control
system consisting a hum
Answers
Inputs for a washing machine:
- Electricity to power the motor, drum, pump and other components
- Water from the water supply
- Detergent and fabric softener added by the user
- User settings for the wash program (hot/cold, water level, spin speed etc)
Outputs from a washing machine:
- Clean clothes
- Wastewater drained out
- Some noise from the motor and drum spinning
The organ-system components of the biological control system for a human are:
Inputs:
- Sensory inputs from eyes, ears, skin, tongue etc which provide information about external environment and internal body states
Components:
- Nervous system (brain, spinal cord, nerves) which processes input and coordinates responses
- Endocrine system (glands) which secretes hormones to regulate processes
Outputs:
The system provides:
- Muscle movements and actions as output responses
- Gland secretions like tears, sweat and saliva as outputs
- Physiological changes in heartbeat, breathing and digestion as outputs
The overall operation is that inputs are detected, processed by the brain and nervous system, which then coordinate output responses via muscles, glands and organs to maintain homeostasis and adapt to the environment. The endocrine system assists the nervous system by secreting hormones that induce slower but longer-term responses.
Some students were building a model of a

F Tissues digest food for the organ
system to absorb.
GCells digest food, which is then

(H)
The organ system uses specialized
cells to digest food.
Answers
The digestive process is divided into four steps: ingestion, chemical and mechanical food breakdown, nutrient absorption, and expulsion of indigestible food.
What does the digestive process entail?
The digestive process starts as soon as something is chewed. In order for food to pass more easily through your esophagus and into your stomach, saliva, a digestive juice produced by your salivary glands, moistens the food. The carbs in food also begin to be broken down by an enzyme found in saliva.
Motility, digestion, absorption, and secretion are the four fundamental functions of the digestive system. Our digestive system transforms our food into energy that we can use.
The digestive system's initial function is to take in food through the mouth. The "ingesting" procedure must take place before anything else can happen.
The complete question is:
Some students were building a model of a digestive system. Which choice best describes a process they should show with their model?

In cocker spaniels, black coats are dominant to red. In a cross between two cockers, the litter showed 2 black and 2 red.
a) What must be the GTs of the parents?
b) Explain why
Answers
If in cocker spaniels black coats are dominant to red and in a cross between two cockers, the litter showed 2 black and 2 red, then the genotypes of the parental are recessive homozygous and heterozygous (question a) because it is the expected proportion 1:1 in a cross with these features (question b).
What are homozygous recessive individuals?
Homozygous recessive individuals are those individuals who have the same gene variant for a given locus which is only expressed when there is not a domain allele.
Therefore, with this data, we can see that homozygous recessive individuals have two recessive alleles and produce 1 to 1 in the progeny when crossed with heterozygous.

when cyclin b is degraded, re-formation of the nuclear envelope occurs which allows phosphatases to dephosphorylate phosphorylated proteins including nuclear envelope lamins.T/F
Answers
when cyclin b is degraded, re-formation of the nuclear envelope occurs which allows phosphatases to dephosphorylate phosphorylated proteins including nuclear envelope lamins. Given Statemnet are true.
Cyclin B is involved in several forms of cancer. Cancer is characterized by hyperplasia (uncontrolled cell development). Because cyclin B is required for cells to undergo mitosis and hence for cell division, cyclin B levels are frequently deregulated in malignancies.
Degradation of the cyclin B component of protein kinase Cdk1/cyclin B is necessary for kinase deactivation and mitotic exit. The ubiquitin pathway, which is involved in most selective protein degradation in eukaryotic cells, degrades cyclin B.
In most eukaryotes, the cyclin B-Cdk1 kinase initiates mitosis. In animal cells, cyclin B shuttles between the nucleus and the cytoplasm during interphase before quickly accumulating in the nucleus during prophase, promoting nuclear lamina disintegration.
