Given that propane has carbon in it, do you think that water could be the only product from the burning of propane? Why or why not?
No. Water cannot be the only product of the combustion of propane because carbon dioxide is also formed simultaneously.
Combustion of propaneGenerally, hydrocarbons undergo combustion reactions with oxygen. When this happens, complete combustion leads to the production of carbon dioxide and water. The general equation for the combustion of hydrocarbons is written as: [tex]C_nH_{2n+2} + (3n+1)/2 O_2 = n CO_2 + (n+1) H_2O[/tex]
Propane is a hydrocarbon with the chemical formula, [tex]C_3H_8[/tex]. Thus, when it burns in oxygen, the equation of the reaction becomes:[tex]C_3H_8 + 5O_2 -- > 3CO_2 + 4H_2O[/tex]
From this equation, we can see that not only water is produced when propane burns in oxygen, but carbon dioxide molecules as well. Thus, water cannot be the only product of propane combustion because another product, carbon dioxide, is also formed.

Problems faced by organisms that live in freshwater are without compensating mechanisms, their bodies tend to take in too much water.
Their bodies have a tendency to absorb too much water since freshwater organisms' environments are hypotonic in nature to their cells, which causes the organisms' bodies to do the same. They are unable to manage their tonicity. Only saltwater causes issues for the creatures who inhabit it.
The osmotic principle states that water travels from a location of low solute concentration (hypotonic) to a region of high solute concentration (hypertonic). As a result, the low solute content in the water creates difficulty for freshwater creatures since they have a tendency to use too much water.

Transcription is mRNA synthesis, which occurs by complementing a segment of the DNA template strand. The translation is the protein growth, which occurs by adding amino acids coded by mRNA codons. C) the polypeptide is 6 amino acids long.
What are transcription and translation?The whole process of protein synthesis includes Transcription and translation.
TRANSCRIPTION
Transcription is the mRNA synthesis process and occurs in the nucleus.
The DNA template strand is read in direction 3'→ 5' to build the mRNA molecule in direction 5'→ 3'. The template strand is the one that is going to be complemented by the mRNA.
mRNA molecule has the same sequence as the DNA coding strand, but it carries uracil instead of thymine.
TRANSLATION
Translation is the process through which polypeptide grows. It occurs in the cytoplasm.
rRNA and tRNA read mRNA in the direction 5'→ 3' and add the correct amino acids to build the new protein.
Amino acids are coded by mRNA codons. Protein synthesis initiates in the AUG start codon -Metionin- and ends when reaching either of the stop codons UAA, UAG, or UGA.
In the exposed example, we have a DNA strand. We know that it is the coding strand, so it has the same sequence as mRNA molecule.
DNA coding strand5' AATCCGTATCTATGACCGTTTGGAAACACTAAGCGGTACTC 3'
mRNA molecule5' AAUCCGUAUCUAUGACCGUUUGGAAACACUAAGCGGUACUC 3'
Kowing mRNA sequence, we can grow the protein.
So first, we need to find the initiation codon (AUG), begining from the mRNA 5' extreme. Then we need to find a stop codon (UAA, UAG, or UGA).
mRNA start codon5' AAUCCGUAUCUAUGACCGUUUGGAAACACUAAGCGGUACUC 3'
mRNA stop codon5' AAUCCGUAUCUAUGACCGUUUGGAAACACUAAGCGGUACUC 3'

5 functions of mesophyte
Answer: Find your 5
Explanation:
Mesophytes generally require a more or less continuous water supply. They usually have larger, thinner leaves compared to xerophytes, sometimes with a greater number of stomata on the undersides of leaves. Because of their lack of particular xeromorphic adaptations, when they are exposed to extreme conditions they lose water rapidly, and are not tolerant of drought. Mesophytes are intermediate in water use and needs. These plants are found in average conditions of temperature and moisture and grow in soil that has no water logging. The roots of mesophytes are well developed, branched and provided with a root cap. The shoot system is well organised. The stem is generally aerial, branched, straight, thick and hard. Leaves are thin, broad in middle, dark green and of variable shape and measurement.[citation needed]For example, in hot weather they may overheat and suffer from temperature stress. They have no specific adaptations to overcome this, but, if there is enough water in the soil to allow this, they can increase their rate of transpiration by opening their stomata, thus meaning some heat is removed by the evaporating water. However these plants can only tolerate saturated soil for a certain amount of time without a warm temperature. In dry weather they may suffer from water stress (losing more water via transpiration than can be gained from the soil). Again they have no specific adaptations to overcome this, and can only respond by closing their stomata to prevent further transpiration. This does actually have some benefits as it reduces the surface area of the leaves exposed to the atmosphere, which reduces transpiration. Prolonged periods of dehydration, however, can lead to permanent wilting, cell plasmolysis, and subsequent death. Since mesophytes prefer moist, well drained soils, most crops are mesophytes. Some examples are corn (maize), cucurbits, privet, lilac, goldenrod, clover, and oxeye daisy

which experimental results would demonstrate that central pattern generators are involved in producing the muscle contractions involved in rhythmic movement?
The experimental result that displayed the central pattern generators' involvement in muscle contractions is that 'an insect in which the sensory afferents from the wings have been cut can fly', which suggests that option C is the right answer.
Central pattern generators are neuronal circuits which when activated produce rhythmic motor patterns such as walking, breathing or flying etc. in the absence of sensory signals. Muscle contraction refers to the activities such as tightening, shortening, or lengthening of muscles when some activity is performed by the body. It is caused due to the information signal received by the brain and then returned back to site of stimuli. The experiments conducted displayed that a deafferented locust could generate rhythmic flight motor patterns in response to non-rhythmic stimulation of the nerve cord.

Darwin's theory of evolution supports the concept of anagenesis (gradualism) of groups (clades) of organisms vs. _
Answer:
Explanation:
Natural SelectionThe theory of natural selection was the main tenet of Darwin's biological evolutionary scheme, although other important aspects included descent, gradualism, the multiplication of species (including geographic speciation), and sexual selection. While incorporating Malthusian aspects of the multiplication of species and population checks, Darwin's insight was that the stronger members of each species would survive and the weakest would be eliminated (become extinct). These concepts formed the basis of natural selection, which was Darwin's ‘mechanism’ of evolutionary change. Darwin argued for a natural process of variation, struggle, and the selection of traits favorable for survival:Owing to this struggle for life, any variation, however slight and from whatever cause proceeding, if it be in any degree profitable to an individual of any species, in its infinitely complex relations to other organic beings and to external nature, will tend to the preservation of that individual, and will generally be inherited by its offspring. … I have called this principle, by which each slight variation, if useful, is preserved, by the term of Natural Selection, in order to mark its relation to man's power of selection (Darwin, 1859: 61).Darwin's theory of natural selection incorporated the idea that all species were linked to one another in time and space by descent. This was expressed through the metaphor of a branching tree of life, where the trunk symbolized the common ancestor from which all animals had originated. Central to this model of evolutionary development was the idea of a haphazard process of evolution, which rejected progressionist notions of linear development. This haphazard process occurred as each species became better adapted to its surrounding environment. Any environmental changes that occurred would affect the development of the species, and could cause species to diverge onto different branches of evolution, and in some cases to become extinct. The branching tree metaphor was considered early in the development of the theory of natural selection, as shown by a sketch in Darwin's Notebook B (Figure 3) and a detailed diagram was included in The Origin (Figure 4). Here the letters A–L represent parent species which resemble each other to varying degrees (thus spaced unevenly). The dotted lines diverging from each original species represent offspring from these species. Through the process of natural selection over many generations, some original species will develop new varieties and others will become extinct. New species varieties are represented at the top of the diagram (a14, q14, and so on). Darwin meticulously explained this diagram in chapter IV of The Origin, and the strength of his account is reinforced through the written description with which he concluded the chapter:
Darwin's theory of evolution supports the concept of anagenesis (gradualism) of groups (clades) of organisms vs. that of natural selection.
What is Darwin's theory of evolution?Charles Darwin's theory or Darwinism is a theory of the biological evolution of different species which are developed by the English naturalist Charles Darwin and others, stating that all of the species of organisms arise and develop through the process of natural selection of the small, inherited variations which increase the individual's ability to compete, survive, and reproduce better in the surrounding environmental conditions in which they live in.
The five major theories given by Charles Darwin include evolution of species as such, common descent, gradualism, multiplication of species, and natural selection of species.

What about plants respiration?Water vapor is lost via the process of transpiration through a plant's stomata. When it's very hot outside, the plant loses water vapor to cool down, and water from the stem and roots flows up or is "drawn" into the leaves. In addition, plant transpiration contributes significantly to the leaf's energy balance by providing evaporative cooling. Additionally, the movement of water and nutrients from the roots to the shoots is accelerated by transpiration. Plants use transpiration for a variety of purposes. The direct effects of transpiration include controlling the plant's temperature and supplying water for photosynthesis. Additionally, it facilitates the movement of glucose and nutrients through the plant's vascular tissues. Plants lose water through a process known as transpiration. A plant's roots can collect up to 99.5% of the water that the plant transpires, which is not used for growth or metabolism.
