0.9%
15%
1.5%
9

Answers

Answer:

Explanation:

The rate = 50000*(x/100) = 450

Multiply both sides by 100

50000 * x = 450*100

50000* x = 45000

Divide by 50000

x = 45000/50000

x = 45/50 = .9%

Answer:

This would be the commission rate because 50000 multiplied by 0.9 is 450.

People's personalities will determine whether they get recruited, promoted, derailed, help others, are viewed as leaders, and other outcomes.  It is obvious that personality type affects health and happiness. Novelty seeking was additionally connected to a liking for salty meals.

Even while research shows that personality type undoubtedly affects health and wellbeing, some diseases are more probable to be impacted by psychological traits than others. For instance, heart disease has a stronger correlation with type of personality than cancer.

The need for novelty has also been associated with a predilection for salty meals, whereas stressed people seem to prefer a much smaller selection of foods. Mood and taste have also been shown to be correlated in both directions. Personality influences whether a person is employed, promoted, derailed, helpful to others, viewed as a leader, and other factors.

Explanation:

If most animals are derived from a single ancestral stock, and if that ancestral stock was radially symmetrical, would the colonial hypothesis or the coenocytial hypothesis of animal origins be more attractive to you? Explain

Answers

The colonial hypothesis of animal origins would be more attractive because the colonial hypothesis posits that animals evolved from colonial protists.

What is colonial hypothesis?

The colonial hypothesis is a theory of animal evolution that proposes that animals evolved from colonial protists. A colonial protist is an organism made up of a group of genetically identical cells that function as a single unit. The cells in a colonial protist are held together by a common extracellular matrix and are able to divide and differentiate in order to perform different functions. According to the colonial hypothesis, animals evolved from colonial protists through a process of specialization and integration of cells.

The cells in the colonial protist became specialized for different functions and became more integrated with one another, eventually giving rise to the complex multicellular animals we see today. The colonial hypothesis is one of several theories that have been proposed to explain the evolution of animals, but it is not widely accepted by the scientific community.

A) The compound that regulates the pathway acts as a competitive inhibitor or a positive allosteric regulator.
B) The enzyme that is regulated by feedback inhibition is usually the last enzyme in the metabolic pathway.
C) The final product of a metabolic pathway is usually the compound that regulates the pathway.
D) The products of the pathway become the reactants for a different reaction, and thus products are unable to accumulate.
E) Accumulation of the product of the pathway increases further formation of that product.

Answers

Answer:

Correct answer is: B) The final product of a metabolic pathway is usually the compound that regulates the pathway.

Explanation:

Feedback regulation of a metabolic pathway is a mechanism by which the end product of a pathway inhibits an enzyme that catalyzes an early step in the pathway, thus preventing the overaccumulation of the product. This is an example of negative feedback, which maintains homeostasis and optimizes the efficiency of the pathway.

For example, in the synthesis of the amino acid isoleucine from threonine, the final product isoleucine binds to the allosteric site of the first enzyme in the pathway, threonine deaminase, and inhibits its activity. This reduces the rate of the pathway and prevents the excess production of isoleucine.

Protein Structure Evaluation Based on Gel Filtration Data A new protein of unknown structure has been purified. Gel filtration chromatography reveals that the native protein has a molecular weight of 240,000. Chromatography in the presence of 6 M guanidine hydrochloride yields a single peak corresponding to a protein of Mr 60,000. Chromatography in the presence of 6 M guanidine hydrochloride and 10 mM b-mercaptoethan yield peaks for protein of Mr 34,000 and 26,000. Explain what can be determined about the structure of this protein from these data?

Answers

Answer:

Based on the given information, the disruption of hydrogen bonds and other weak forces that helps in integrating the structure of the protein is mediated by guanidine hydrochloride, that is, it denatures the protein. Only a solitary peak of Mr 60000 is witnessed post denaturation. This clearly shows that only one peptide of Mr 60000 is left in the solution post denaturation.  

Of the entire protein of molecular weight 240000 D, post denaturation only the protein of 60000 D got left, which shows that the protein comprises four subunits of 60000 D, and thus, is a tetramer.  

With the addition of 10 mM beta-mercaptoethanol, the protein got further dissociated into two subunits of molecular weight 34000 D and 26000 D showing that each subunit of protein was linked by disulfide bonds, which got broken with the addition of beta-mercaptoethanol.

Describe the role of GA in a-amylase production and in germination. Provide evidence for your claim

Answers

Gibberellic acid (GA) plays a crucial role in a-amylase production and germination. GA stimulates the synthesis and release of a-amylase enzymes, which hydrolyze starch into sugars during germination. Experimental studies have demonstrated that the application of GA accelerates a-amylase production and enhances germination in various plant species

In terms of a-amylase production, GA stimulates the synthesis and release of this enzyme. a-amylase is responsible for breaking down starch into simpler sugars, which are then utilized by the plant for growth and development.

Studies have shown that applying GA to plant tissues or seeds results in an increased production of a-amylase, facilitating the conversion of stored starch into energy-rich sugars.

Regarding germination, GA is involved in breaking seed dormancy and promoting the growth of the embryonic plant.

It stimulates the production of hydrolytic enzymes like a-amylase, which enable the hydrolysis of starch reserves in the endosperm, providing the energy needed for germination and seedling establishment.

Additionally, GA helps in cell elongation and division, promoting the growth of the embryo and the emergence of the radicle.

Evidence for GA's role in both processes includes studies where the exogenous application of GA to seeds or plant tissues has been shown to enhance a-amylase production and promote germination.

Conversely, inhibiting GA synthesis or action results in reduced a-amylase activity and impaired germination. These findings support the critical involvement of GA in both a-amylase production and germination processes in plants.

The human body produces 60 billion (60,000,000,000) new cells per day. How many cells does it produce in one hour?

Answers

Answer:

E.g. E. coli—20 min, so in an hour 1 cell would turn into 8.

Given that 60 billion cells are produced in a day in the human body, the number of cells that will be produced in an hour can be calculated by dividing the number of cells by the number of hours in a day. There would be approximately 2.5 billion cells produced in one hour.

How frequently are the cells in our body renewed?

The human body regularly replaces its own cells. Every day, roughly 330 billion cells, or 1% of all our cells are replaced. The equivalent of a new you will have been replenished in 80 to 100 days with 30 trillion.

Each second approximately one million cells of the body die which means 1.2 kg of the cells are destroyed each day. All the cells in the body have a definite lifespan after which they are replenished.

In other words, how are we speeding up the effects of the competitive exclusion principle and thereby altering the outcome of that ecosystem's natural succession

Answers

Answer: Overgrazing, overfishing, and forest fires

Explanation:

Competitive exclusion principle two species which have the same ecological niche cannot exists together as such species will be competing for the same resources. The species which is superior over the other will receive the resources and the other species having no competitive advantage will not survive in future.

According to the given situation, human being is the most superior species on earth and have competitive advantage of thinking ability and intelligence over other species. Succession are the changes that occur in the biotic community of an ecosystem with respect to time.

The human beings can speed up the effects of the competitive exclusion principle by various ways: Overgrazing, overfishing, and forest fires. The overgrazing of the cattle in the field can remove the vegetation cover of the region and the land will become barren so instead of progressive succession in terms of vegetation cover the succession will again re-initiate in terms of primary succession if environment supports.

Overfishing can cause the exclusion of some valuable species of fish and there will not be evolution of such species and will alter the outcome of natural succession.  

Forest fires can affect both floral and faunal species some species may tolerate the fire and will survive and some precursors like roots of the plants can support new individual plants. This will again alter the outcome of natural progressive succession in an ecosystem.

Answers

The Calvin cycle is a series of light-independent reactions that occur in the chloroplasts of plants.

These reactions are responsible for converting carbon dioxide into glucose, which is the main source of energy for the plant. The Calvin cycle is also known as the Calvin-Benson cycle or the C3 cycle. The cycle consists of three main stages: carbon fixation, reduction, and regeneration. During carbon fixation, an enzyme called Rubisco combines carbon dioxide with a five-carbon molecule called RuBP. This results in the formation of two three-carbon molecules known as PGA. In the reduction stage, ATP and NADPH, which are produced during the light-dependent reactions, are used to convert PGA into G3P. Some of the G3P molecules are used to regenerate RuBP, while others are used to produce glucose and other organic compounds.
