you have before you an unknown organism, which you examine carefully. which of the following would convince you it is a pseudocoelomate?

Answers

To know the organism is pseudocoelomate it should have a bodily cavity that forms between the mesoderm and endoderm during embryonic development.

An creature with a body cavity known as a pseudocoelomate does not have a true coelom, which is where the body cavity originates from. Since the bodily cavity of a pseudocoelomate originates from the blastocoel, or cavity, within the embryo, it is sometimes referred to as a blastocoelomate. A peritoneum that serves as a barrier between the fluid and the bodily cavity lines a real coelom. The bodily fluids bathe the organs in a pseudocoelomate and draw oxygen and nutrients from the cavity fluid. All metazoan species share the condition of having a blastocoel in the embryo.

each of the following effects is associated with the action of postganglionic sympathetic fibers except___ A) increased sweat secretion B) dilation of the pupils C) reduced circulation to the skin D) decreased heart rate E) increased blood flow to skeletal muscles

Answers

The correct option is D i.e. decreased heart rate is the effect which is not associated with the action of postganglionic sympathetic fibers.

Norepinephrine, or noradrenalin, is a neurotransmitter used by the sympathetic division's adrenergic postganglionic fibers. The postganglionic neurons in sweat glands produce acetylcholine to activate muscarinic receptors in the sympathetic nervous system, whereas the postganglionic fibers of the parasympathetic division are cholinergic and use acetylcholine as a neurotransmitter. Post-ganglionic neurons are similar to the chromaffin cells of the adrenal medulla, which develops simultaneously with the sympathetic nervous system and performs as a modified sympathetic ganglion. Presynaptic nerve axons in the sympathetic nervous system terminate in the paravertebral or prevertebral ganglia. The paravertebral ganglia are always reached at that level by the spinal nerve from which the axon originated. Preganglionic neurons release acetylcholine at synapses within the ganglia, which activates nicotinic acetylcholine receptors on postganglionic neurons. With two notable exceptions, postganglionic neurons respond to this stimulus by releasing norepinephrine, which stimulates adrenergic receptors on the target tissues in the periphery. By activating specific tissue receptors, the sympathetic nervous system's effects are triggered.

To make a buffer you will need to mix a solution of a weak base with a weak acid. We will be making a phosphate buffer by combining a phosphate base K2HPO4 (dibasic monohydrogen phosphate) with a phosphate acid KH2PO4 (monobasic dihydrogen phosphate). Equal amounts of each should provide a solution with a pH of 6.8.

Determine the mass of 1 mole of each of the phosphate salts
​1 mole of K2HPO4

​1 mole of KH2PO4

To make a 0.1 M solution of K2HPO4 how much salt should you add in a 100 ml solution?

To make a 0.1 M solution of KH2PO4 how much salt should you add in a 100 ml solution?

Answers

By the principle of Henderson-Hasselbalch equation:

Mass of 1 mole of each of the phosphate salts 1 mole of K₂HPO₄: 0.575 gm

Mass 0.1 M solution of KH₂PO₄ in a 100 ml solution: 0.912 gm

What is Henderson-Hasselbalch equation?

In biological and chemical systems, the Henderson-Hasselbalch equation defines the link between pH as a measure of acidity and the acid dissociation constant (pKa). The equation is particularly useful for calculating the pH of a buffer solution and determining the pH of equilibrium in acid-base processes.

Phosphoric acid pKa's are 2.3, 7.21 and 12.35.

Our required pH is 6.5, so 7.21 will be used.

Hence, mono-potassium dihydrogen phosphate (KH₂PO₄) and dipotassium mono-hydrogen phosphate  (K₂HPO₄) will be used.

Handerson-Hasselbach equation:

pH = pKa + log ([A⁻]/[HA])

Therefore, A⁻ is K₂HPO₄ concentration, and for HA is KH₂PO₄ concentration:

or, 6.5 = 7.21 + log(A⁻/HA)

or, log(A⁻/HA)=-0.71

or, A⁻/HA = 0.49

We know that total salt concentration = 0.1 M

HA+A=0.1

A⁻/HA=0.49

So, HA+0.49 HA=0.1

[HA] = 0.1/1.49 = 0.067M

[A] = 0.1-0.067M = 0.033M

Therefore, the concentration of K₂HPO₄ = 0.033M

and the concentration of KH₂PO₄ = 0.067M

Since, we are preparing 100 ml or 0.1 L  of the solution,

Thus, the weight of K₂HPO₄ = (0.033M x mol.weight)x 0.1 L  

                                               =  (0.033M x 174.2 g/mol)x 0.1 L

                                                = 0.575 g of K₂HPO₄ required for 0.1 L

Similarly, we can calculate for KH₂PO₄:

or, wieght of KH₂PO₄   = (0.067M x mol.weight)x 0.1L  

                                      = (0.067M x 136.086 g/mol)x 0.1L

                                      = 0.912 g of KH₂PO₄ required for 0.1L buffer solution.

Therefore, we need to take 0.575 g of K₂HPO₄ + 0.912 g of KH₂PO₄ and dissolve them in 100 ml water to prepare 100mL of a 0.1M potassium phosphate buffer of pH 6.5.

The statement is discussing the idea that while private property allows individuals to define themselves and frees them from the burdens of daily subsistence, it should not be accumulated to such an extent that it prevents others from obtaining the necessities of life.

In summary, the statement highlights the value of private property in terms of self-expression and freedom from daily struggles. However, it also emphasizes the need to balance individual accumulation with ensuring that everyone has access to the necessities of life.Here is a step-by-step explanation of the main points: 1. Private property helps people define themselves: When individuals have the freedom to own and control property, they can express their identity, personal preferences, and values through their possessions. For example, someone may choose to decorate their home in a way that reflects their taste and interests. 2. Private property frees people from mundane cares of daily subsistence: By having ownership of property, individuals can secure their basic needs and focus on other aspects of life beyond survival.

For instance, if someone owns a house, they don't have to worry about finding shelter every day and can instead pursue education, work, or leisure activities. 3. Private property is finite: Private property rights are typically limited to prevent unfair concentration of wealth and resources. This means that there are limits on how much property an individual can accumulate. 4. No individual should accumulate so much property that others are prevented from accumulating the necessities of life:

The products of the Calvin cycle reactions are sugar, O2, NADPH, and ADP + Pi, thereby the correct option is C.

What are the Calvin cycle reactions?

The Calvin cycle reactions are a series of metabolic processes that occur in plants in absence of light which are fundamental to generating glucose or simple carbs (i.e. sugars) and thus obtaining chemical energy for the plant.

Therefore, with this data, we can see that the Calvin cycle reactions generate sugar and or glucose in the plant and they are reactions that occur in the absence of sunlight.

We will now discuss one way to generate a growth curve using the standard curve relating absorbance and viable count. Typically to generate a growth curve a microbiologist inoculates broth with the organism he/she desires to study. The flask containing the broth is placed in an incubator (usually a shaking incubator). At set time intervals, an aliquot is withdrawn from the culture, and the absorbance of this aliquot measured at 640 nm. Using the standard curve, the number of cells at each time period is determined. A flask of E. coli Hfr was inoculated and incubated with shaking for nine hours. At half hour intervals, the absorbance was measured. The following results were obtained. Note that starting at 6.5 hour, the culture had to be diluted in order to read on the spectrophotometer. To do this, 1 ml of culture was mixed with 1 ml of uninoculated medium.

where are ribosomes made; where are ribosomes located; nucleus; sac-like structures that break down and digests substances in the cell; ribosomes function; golgi apparatus function; function of ribosomes in plant cell; ribosomes structure

Answers

The cellular machinery responsible for assembling proteins, known as ribosomes, are synthesized in the nucleus (plural, nuclei), which also houses the genetic material, or DNA, of the cell.

The majority of ribosomes are found dispersed freely throughout the cytoplasm and bound to the nuclear envelope and endoplasmic reticulum, respectively. The process of making proteins in a cell takes place at an intercellular structure called a ribosome, which is made of both RNA and protein. Proteins obtained from the ER are further processed and sorted in the Golgi apparatus, or Golgi complex, where they are eventually transported to lysosomes, the plasma membrane, or secretion. The region where proteins are made is located in the ribosomal large subunit, which is known as the 60S in plant cells.The process of making proteins in a cell takes place at an intercellular structure called a ribosome, which is formed of both RNA and protein. The messenger RNA (mRNA) sequence is read by the ribosome, which then translates the genetic code into a specific string of amino acids that develop into extended chains and fold to form proteins.

Hence, ribosome is important cellular organelle.

morning commuter traffic in cities contributes toindustrial smog. in this type of air pollution, a mixing ofnitrous oxide from certain plants, nitrogen oxides from cars, and uv radiation from the sun results in a variety of pollutants, such as ground-level ozone, which can cause coughing and breathing problems.

Answers

Cities' morning commuter traffic causes photochemical smog.

When certain plants' hydrocarbons, automobiles' nitrogen oxides, and the sun's UV rays interact, they produce a range of pollutants, including ground-level ozone, which can impair breathing and induce coughing.

The photochemical interaction of hydrocarbon and nitrogen oxides in the lower atmosphere, which mostly relies on sunshine, results in photochemical smogs. Ozone gas is created when a hydrocarbon reacts with nitrogen oxide in the presence of light, although nitrogen oxide can also react with sunlight on its own to create nitrogen dioxide. Smog is created as a result of this.
