How is carbon dioxide produced in a cement plant
Carbon dioxide is produced in a cement plant when limestone is decomposed.
Cement is produced using lime stone as raw material. The limestone is decomposed according to the reaction;
CaCO3(s) -----> CaO(s) + CO2(g)
The CaO is used to produce cement while CO2 is a waste gas that escapes.
Hence, carbon dioxide is produced in a cement plant limestone is decomposed.

Explain what happens to the available energy within each level when more organisms exist at that level.
Answer:
Within all biological communities, energy at each trophic level is lost in the form of heat (as much as 80 to 90 percent), as organisms expend energy for metabolic processes such as staying warm and digesting food (see biosphere: The organism and the environment: Resources of the biosphere: The flow of energy).
Explanation:
Within all biological communities, energy at each trophic level is lost in the form of heat (as much as 80 to 90 percent), as organisms expend energy for metabolic processes such as staying warm and digesting food (see biosphere: The organism and the environment: Resources of the biosphere: The flow of energy).
Energy can neither be created nor be destroyed. The available energy within each trophic level is lost as heat and only 10% of the energy is utilized.
The 10% rule can be explained as:
1. Energy in the different trophic levels is passed and the rest of the energy is lost as heat.
2. The law suggests that only 10% of the energy is transmitted to different trophic levels.
3. Approximately 80%-90% of the energy is lost in the form of heat. The organisms utilize energy for metabolic processes and keep them warm.
Thus, the rest of the energy is lost as heat and only 10% of the energy is transferred to the next trophic level.

Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease affecting adults (~30,000 in U.S.). It is a progressive, debilitating neuromuscular disorder that generally strikes in mid- to late-life (40-70 years) and can rapidly progress to death (3-5 years from onset). ALS is characterized by selective loss of motor neurons in spinal cord, which causes loss of skeletal muscle and weakness. Motor neurons in the largest motor units appear to be most vulnerable. Based on this, which type of motor neurons and muscle fibers would you expect to be most susceptible
Answer
Upper and Lower motor neurons, and Voluntary muscles.
Explanation:
Structurally,the motor neurons in the Brain are called the upper motor neurons.While the motor neurons in the spinal cord and the brain Nuclei are called the lower motor motor neurons.
Therefore, transmission of sensory impulses from the brain through the upper motor neuron are sent to the spinal cord through the lower motor neurons. These are eventually sent to the muscles(voluntary muscles) the effectors to bring response.
However, in ALS both the upper and lower motor neurons degenerate and die.Therefore transmission of action potential is impeded.Thus the voluntary muscles are made redundant with no sensory information and therefore they twitch (this is called fasciculations) and progressively undergo waste away.
As this progress the ability of the brain to initiate action potential for sensory information and its propagation is lost.
Therefore weakness of muscles and stiffness results,followed by complete loss of sensory transmission and inability of the individual to respond to sensory stimulus of walking, standing, eating, and breathing.Slurred and nasal speech,and muscles cramps are other symptoms
At advanced stage loss of life usually results from the respiratory failure.
it occurs mostly in the Caucasians and non-Hispanics between the age of 55-75,and common in males than females.It causes are blend of genetic and environmental factors.
Medication,therapy-physical and speech therapy are some means of treatments.
Why do phospholipids make a phospholipid bilayer with the heads facing out towards water and the tails facing each
Answer: See below
Explanation:
Phospholipids are organized into two layers. The phospholipids have a head known as a 'hydrophilic' or water-loving head. Any water will come into contact with this region of the phospholipid. In contrast, the phospholipid tails are hydrophobic, or 'water hating'. They will position themselves such that they face inwards and are not in touch with any water. Because of these features, the bilayer is created with the phospholipid heads facing outwards and the tails facing inside.
2. What is an example of something studied on the molecular level (as opposed to the atomic level)?
hydrogen
oxygen
water
protons
Answer:
Something studied on the molecular level is the water.
Explanation:
Water is a molecule formed by two hydrogen atoms and one oxygen atom, whose chemical representation is H₂O. It is a molecule whose polarity makes it a universal solvent of other polar molecules.
The molecular level corresponds to the level of organization where two or more atoms unite to form molecules or substances, united by chemical bonds. H₂O is studied at this level due to its chemical structure.
With respect to other options:
Hydrogen and oxygen are atoms, and correspond to the level of atomic organization.Protons are particles that are part of an atom, and correspond to the subatomic level.the interactions of abiotic and biotic factors results in condition that are suitable for some oranisms but not for others?
Answer:
Abiotic factors can be extremely broad. Sunlight, air, soil, rock, minerals, water, etc. are all biotic factors. Sunlight provides energy that plants utilize to grow, which ultimately holds up the whole biotic community of an ecosystem. Air also interacts with plants, helping them grow by providing a source of carbon (CO2) and other nutrients.
In general, abiotic factors like rock, soil, and water interact with biotic factors in the form of providing nutrients. Just as humans mine mountains and cultivate soil, rock and soil provide resources for plants, and plants cycle the nutrients through so they (usually) end up back in the ground where they began. The water, phosphorus, nitrogen, and carbon cycles are examples of this.
Another way biotic and abiotic factors interact is that biotic factors often change the geology and geography of an area. Geologically, organisms create topsoil by breaking down rock layers and dying, which provides detritus with which to form new soil and return nutrients to the ground

Determine the amino acid sequence to AATACGGCC
Answer:
UUA UGC CGG
Explanation:
if its not that is there perhaps a table for the sequences
The amino acid sequence for the given DNA sequence AATACGGCC can be determined by transcribing the DNA into mRNA and then translating the mRNA into amino acids using the genetic code.
The given DNA sequence is AATACGGCC.
The mRNA obtained for this DNA sequence through transcription will be:
UUAUGCCGG.
Using the genetic code, each codon (triplet of nucleotides) is translated into its corresponding amino acid as follows:
1. UUA - leucine
2. UGC - methionine
3. CGG - proline
Therefore, the amino acid sequence for AATACGGCC is Leucine-Methionine-Proline or Leu-Met-Pro.

Can convection take place in the water if it is heated at the top?
Answer: If the heating is done on one small area on the top, there will be convection. If the heating is restricted to a small fraction of the heating area, then within that area the heating will go deeper than anywhere else on the surface. Then the unheated area will have a shallower region of high temperature. Then some convection will occur in the deeper layers, causing some motion on top.
This happens quite a bit during welding. Convection is very significant in welding, even when the heating is from the top.

Explain the mechanism maintaining osmotic gradient in renal medullary intestitium
In the inner medulla, urea recirculates, creating a greater osmotic gradient. It follows the concentration gradient formed by ADH-sensitive water reabsorption into the interstitial space from the collecting duct. The remaining water is drawn from the descending structures by increased interstitial osmolarity.
To maintain the vertical osmotic gradient, the blood supply to the renal medulla serves as a countercurrent exchanger. - The medullary vertical osmotic gradient is maintained by the vasa recta.
It enhances both water and urea permeability in the inner medullary collecting ducts, allowing urea to diffuse passively down its concentration gradient into the interstitial fluid. This contributes to the osmotic gradient and aids water absorption.

Which does an organism need to undergo cellular respiration?
A. food and oxygen
B. water and sunlight
C. sunlight and oxygen
D. carbon dioxide and energy
Answer:
C. sunlight and oxygen
Explanation:
Cellular respiration is quite simply the conversion of chemical energy from oxygen into ATP in order to release waste by-products.
Oxygen is needed for this process to take place because it helps break down the necessary nutrients which will in turn generate ATP, and other processes.
Therefore, an organism needs oxygen and sunlight to undergo cellular respiration.
