Answer:
Differentiation occurs because as organizations grow and become more complex, they establish a division of work. Vertical differentiation is a ranking of power with reporting relationships established to connect organizational roles and sub-units. Where horizontal differentiation are group roles according to task responsibilities, establishes division of power, and forms sub-units.
Would meteorology be a useful science to apply to the study of Mercury the innermost and smallest planet.. Explain !
Answer:
Yes, meteorology could be useful when studying other planets such as Mercury and Mars; atmospheric science has been extended to the field of planetary science and the study of the atmospheres of the planets of the solar system.
It would be ineffective since these two planets have extremely thin atmospheres. They experience very few meteorological processes.
What are meteorological processes?Weather or modifications in the Earth's atmosphere are examples of meteorological phenomena.
If you want to be a meteorologist a weather expert one should pursue a meteorological career. Fog, downpours, tornadoes, and hurricanes are examples of meteorological events.
Meteorology is essential because air quality has an impact on life. First and foremost, weather prediction is critical in urban management.
Cities are preparing for severe weather events such as tornadoes and snowstorms in order to avoid disasters. Second, agriculture relies on long-term weather forecasting.
Thus, as these celestial bodies have extremely thin atmospheres, it would be ineffective. They are subjected to very few meteorological processes.

1. In relation to homeostasis, explain why a person with toxic goiter tends to sweat profusely.
2. Explain how the action of a peptide hormone is similar to the action of the neurotransmitter norepinephrine.
Answer:
In relation to homeostasis, explain why a person with toxic goiter tends to sweat profusely.
When there is hyper secretion of thyroid hormone in an individual a condition called toxic goiter occurs.Here the goiter swells at the neck region.Although this may pose no potential risk, but it maybe cancerous.
Thyroid hormones(T3,T4),increases calorinogenesis,that is they are carlorinogenic(,generate it in the body).This increases the oxygen consumption of the heart, and therefore overall body temperature.
To control the body temperature, the body thermo regulatory mechanisms set in, as the blood convey the heat to the thermo receptors in the hypothalamus. Vasodilation (widening of blood capillaries) occurs as the hypothalamus control the body temperature.
Therefore, as the heat leaves the body, through the capillaries close the the skin surfaces,the body need to produce sweat to conveyed the heat which cools the body temperature,hence sweating .
2. Explain how the action of a peptide hormone is similar to the action of the neurotransmitter norepinephrine.
This is because norepinephrine. act as hormones when secreted by Adrenal gland directly into the blood streams and as neurotransmitter when produced from the CNS and sympathetic nervous system.
Generally,from transcription by the DNA, peptide hormone are transcribed by the mRNA,and the protein is translated into corresponding proteins by the tRNA.And from this exhibited their dominant effects on the endocrine systems.
Generally, norepinephrine. is specific in mode of actions.It binds to specific receptor at the cell surfaces to produce it effects. Likewise peptide hormones are also receptor specific binding. Thus these are the similarities

One popular evolutionary model for the origin of flight in vertebrates is that flight evolved in:_______.
Answer:
skydiving behavior
Explanation:
The flight is an amazing adaptation that consists in the use of aerodynamic forces by flapping the wings. In vertebrates, flight evolved in three independent events: in pterosaurs (i.e., prehistoric winged reptiles), birds, and bats (mammals). In tetrapods, i.e., vertebrates with four legs, it is believed flight had a gliding origin, thereby this feature would have emerged as a consequence of the skydiving behavior necessary to steer the descent.

Which three elements are often found in organic compounds?
Carbon, hydrogen, and oxygen are the three major elements found in organic compounds. Apart from that, nitrogen, phosphorus, etc. are also seen in organic molecules or compounds.
What is an organic molecule?Organic molecule examples are carbohydrates, proteins, lipids, etc. that are found in the bodies of living animals and plants. Carbohydrate molecules, such as glucose, are composed entirely of carbon, hydrogen, and oxygen, whereas proteins are composed entirely of amino acids. Each amino acid is made up of carbon, hydrogen, oxygen, and nitrogen, and a lipid is entirely made up of only carbon and hydrogen.
In organic molecules, these three remain in high proportion, as a result of which they can be easily broken down by the enzymes in our body or by decomposers after death. All three of these enter the atmosphere via the carbon cycle, for example.
Hence Carbon, hydrogen, and oxygen are the three major elements found in organic compounds.

Compare plasma emission with fluorescence by indicating what is common and what is different for the two light emitting mechanisms.
Answer:
Plasma is a state of matter, generated when a gas of ions and atoms, have some of their orbital electrons and free electrons removed. Artificially, plasma can be generated by heating an electrically neutral gas, or subjecting the gas to a strong electromagnetic field until the gas becomes increasingly electrically conductive. This excited atoms and ions then emit electromagnetic radiation usually within the visible range, at wavelengths characteristic of the particular gas used, and are confined by a strong magnetic field.
On the other hand, fluorescence occurs when an excited molecule, atom, or subatomic particles like electrons relaxes to a lower energy state (possibly the ground state) by emitting energy in the form of a photon. It may have been directly excited from the ground state by absorbing energy in the form of a photon, subsequently emitting a photon of lower energy as it relaxes back to its initial lower state.
The common characteristics between these two phenomenon is that they both lead to the emission of energy in the form of photons, which is the unit of an electromagnetic energy or wave.
The difference is that plasma emission can only occur at a very high temperature, whereas fluorescence can occur at a wide range of temperatures between high and low temperatures.

If a mutation occurred that increased the number of exons in a sequence of DNA, what impact would this have on the protein formed from the gene
Answer:
See the answer below
Explanation:
An increase in the number of exons in a sequence of DNA would result in another protein with a longer amino acid sequence.
Exons are the coding part of a gene as opposed to introns. After transcription, the non-coding part of the gene - the introns - are removed by splicing and the exons are joined back together. The final RNA that will undergo translation consists of only exons.
The longer the exons in a gene, the more the codons present in the corresponding mRNA from the gene, and the more the number of amino acids that would be translated from the mRNA. A longer amino acid chain would result in a different protein.
Hence, a mutation that causes an increase in the number of exons in a sequence of DNA would result in a different protein with a longer amino acid sequence.

Which of the following is major characteristic of fungi that distinguishes them from other eukaryotes? Which of the following is major characteristic of fungi that distinguishes them from other eukaryotes? Cells with nuclei and mitochondria Sessile lifestyle Decomposition of dead organisms Acquiring nutrition through ingestion Nutrient acquisition via external digestion
Answer:
Nutrient acquisition via external digestion is the correct option.
Explanation:
Fungi are group of eukaryotic organisms that have no chlorophyll, heterotrophs, have cell walls made up of chitin and reproduce through spores.
Fungi get their food from organic compounds in the environment.
Fungi acquire their nutrients via external digestion because they did not ingest good substances into their body rather they release digestive enzymes into the food and digest it external. After that the food is absorbed from the external digestion.
Acquisition of nutrients through external digestion distinguishes fungi from other eukaryotes.
What is the mode of nutrition in fungi?Unlike algae fungi are heterotrophic, that is, they depend on food from their surroundings to attain energy. Like plants, they do not carry the process of photosynthesis as they lack chlorophyll. Unlike animals, fungi do not possess the tendency to ingest their food.
Fungi discharge certain kind of digestive enzymes into their food and digest it externally. They captivate the molecules of food, which they get by the process of external digestion. Fungi are able to digest food efficiently due to the presence of long and thread-like projections known as hyphae that surround and grow around the source of food.
Thus, the correct statement is nutrient acquisition through external digestion.

Cats are smaller animals than humans. Which would you expect to have a (relatively speaking) more active thyroid glan
Answer:
A final conclusion is not possible from this information
Explanation:
In mammals, the thyroid is an endocrine gland composed of two lobes that are connected by a bridge of tissue referred to as thyroid isthmus. The thyroid gland produces different types of hormones including calcitonin, triiodothyronine and thyroxine. These hormones are known to increase basal metabolism and thus affect metabolic-associated mechanisms including appetite, nutrient absorption and gut motility. However, thyroid hormones are not directly associated with the growth rate. It is important to note that the growth hormones are synthesized by the pituitary gland.

Imagine you are working in a real lab setting and when you test the catalase and water together you see a reaction. What does this tell you?(select all that apply) - catalase is not specific to hydrogen peroxide -posible contaminant in the water causing a reaction -catalase is the negative control -you must complete the experiment again to verify your results
Answer:
-possible contaminant in the water causing a reaction
-you must complete the experiment again to verify your results
Explanation:
The enzyme catalase is present in all living organisms and it functions in the breakdown of the hydrogen peroxide into water (H2O) and oxygen gas (O2).
Catalase is specific to hydrogen peroxide. Catalase and water reaction is seen in the lab test because there is the possibility of water contamination and maybe the reaction is not correctly evaluated, so one must complete the experiment again to verify the result.
Hence, the correct options are 2nd and 4th option.
If you are working in a real lab setting and you found out that testing the catalase using water produced a reaction, it is highly likely that the water is contaminated.
Catalase is an enzyme that is substrate specific and its substrate is hydrogen peroxide. The enzyme breaks down hydrogen peroxide to produce water and oxygen. The latter is often seen as bubbles in reactions and the equation is as follows:
[tex]2H_2O_2 ---> 2H_2O + O_2[/tex]
Ordinarily, catalase will not produce any reaction with water. However, if the water contains a slight amount of hydrogen peroxide, such water might be seen as causing a reaction with catalase.
