Answer 1

Answer:

is always 46

Explanation:

46 is the correct answer

Answer 2

Answer:

the answer is a.

Explanation:

if you are talking about only within a specific species, then the number of chromosomes is supposed to stay constant within that species. however, chromosome disorders do exist, but they are relatively rare.

What was the experimental variable we tested in the lodine Clock Reaction?

Answers

Answer:Experiment 1084-04: lodine Clock Reaction Purpose Determine the rate law for an iodine clock reaction and study the influence of st on that reaction abruptly that it can be as startling as the sudden sound of an alarm clock, hence the clock reaction Background Information chemical equations can be written for chemical reactions, only some will proceed while others do not. Among the ones that do proceed some reactions occur as soon as reactants are mixed, while others occur over minutes, hours, or n over several years. What are the controlling in predicting if a reaction will take place and the speed at which it will? Thermodynamics can answer the question, "Will the reaction take place?" Once the reaction is capable of proceeding kinetics can answer the other question, "How fast You will study the rate of the reduction of potassium persulfate, KoS Os, with sodium iodide, Nal. The net ionic equation for the reaction is eve The rate law for this reaction is in the form of And you will need to determine the reaction orders a and b, as well as the rate constant, k. Keep in mind that exponents can not be determined by jus looking at the chemical equation the reaction will take place? The rate of a reaction is defined as the increase in molar concentration of product of a reaction per unit time or the decrease in molar concentration of reectant per unit time. The usual unit for the rate is moles per liter per sec (mol/L s or M/s). Experimentally, it has been found that a reaction rate depends on the concentrations of the reactants. Usually a higher reactant concentration increases chance of collision among the reactants per unit time causing a faster reaction rate. An equation describing the relationship between the reaction rate and the concentration of the reactants You will need a way to determine how much of the reactants were spent over the given time period. Preferably, the concentrations of the reactants should not change too much; therefore the reaction rate can be represented by the initial concentrations of reactants (the initial-rate method). In this experiment, we will couple another reaction that consumes the product, 12 very quickly. The new reaction is the reduction of is called a rate law. For the elementary reaction Note that l2, which was produced in reaction (1) is consumed as fast as it is produced by reaction (2) to regenerate two l. i.e. [门is kept constant. By keeping [S203-9 much smaller than the initial concentration of S,0, we can assure [S20,1 is also kept nearly constant when S203 is completely consumed. At this point, the 12 is no longer eliminated by the reaction and starts to accumulate. This point is signaled by sudden appearance of the dark color from the interaction of l2 with starch indicator. We can measure the time elapsed till the color appears Rate k [AIB] The proportionality constant, k, is called the ate constant in the relationship between the rate nd concentrations. The rate constant has a fixed alue as long as the reaction temperature is held nstant. The exponents, a and b, are called the action order, and are frequently, but not always, egers. More importantly, they must be termined experimentally In this experiment you will determine the rate an iodine clock reaction, and study the effects of perature and a catalyst to the reaction rate ugh there are several versions of an iodine k reaction, all of them share a common feature: completion of the reaction is signaled by the en appearance of a dark purple color. This is characteristic of the interaction between cular iodine and starch. When the reaction is ed out correctly, this color will appear so According to the reaction stoichiometries of reactions (1) and (2), two molecules of S203 are required to counteract the consumption of one molecule of S20a2. Since S2032 would have been completely consumed when the dark purple color appeared, the Δ[SO ] should be % of the initial concentration of S203 15-08-2] = ½ initial [S,03-21

If doctors disinfect hands before delivering babies, then there will be less childbed fever.

o If a woman goes into the hospital then she will die of childbed lever.

Answers

The investigation for death of women in maternity ward is identified by scientific method of hypothesis testing.

The null hypothesis statements and alternative hypothesis statement can be as,

H0 : Doctors caused child bed fever.

Ha : Midwives caused child bed fever.

Child bed fever is the infection in some part of female reproductive organs usually ovary which causes the abortion of a child or premature child birth.

The hypothesis to check Dr.Ignaz have to make a null hypothesis statement against which there will be alternative hypothesis statement which will cause the observation and then reaching a conclusion.

find evidence that supports a scientific position.



find evidence that proves a scientific position.


find evidence that disproves a scientific position.

Answers

It’s to find evidence that supports a scientific position! It’s actually in the definition, if you search up corroborate! Really hope this helps ya, and have a great rest of your day.

The most correct option as to what corroborating information means would be to find evidence that supports a scientific position.

Corroborate is an English word that means 'to agree with' or 'give credence to'.

Hence:

Finding evidence that opposes a scientific position is a wrong option because that is the complete opposite of what corroborate means. Finding evidence that approves a scientific position is also a wrong option because corroborating a statement does not necessarily make the statement to be scientifically correct.Finding evidence that disproves a scientific position is also incorrect. Corroborate neither translates to approve nor disprove,

Therefore, the correct option that clearly explains what corroborate means in the context of science is to find evidence that supports a scientific position.

¿Qué opinas sobre la problemática del agua en el Perú y el mundo? Cómo ciudadano responsable ¿Qué acciones estas realizando para valorar este recurso?​

Answers

El agua es un elemento relativamente escaso y por lo tanto debe ser cuidadosamente utilizado. En América Latina la distribución de las precipitaciones hace que la disponibilidad de este recurso sea desigual dentro de la región, siendo por lo tanto especialmente importante cuidarlo a fin de evitar el agravamiento de la escasez de agua potable.

El agua es fundamental para la vida ya que este elemento cumple muchas funciones dentro de los sistemas biológicos las cuales incluyen, entre otras:es un sustrato imprescindible de muchas reacciones químicas que se producen dentro de la célulaayuda a la digestión de alimentosmantiene la temperatura corporal dentro del rango aceptable para la vida, etc.

El agua potable (apta para consumo) es también fundamental para evitar la aparición y propagación de enfermedades tales como diarrea, cólera, fiebre tifoidea, poliomielitis, etc.

De acuerdo al Informe Anual del Servicio de Aguas de Lima, aproximadamente el 93% de la población peruana posee servicio de agua potable.

América Latina posee aproximadamente el 25-30% de los recursos hídricos del planeta; sin embargo, su distribución dentro de la región es desigual, con áreas totalmente desertificadas y otras que actualmente sufren inundaciones periódicas.

Esta situación se encuentra agravada por las consecuencias del cambio climático, las cuales generan una mayor inestabilidad en la distribución y estacionalidad de las precipitaciones.

El cuidado de la cantidad y calidad del agua disponible es fundamental para mantener la biodiversidad de las especies alrededor del planeta y asegurar nuestra salud, como así también para garantizar la vida de las generaciones venideras.

La ONU (Organización de Naciones Unidas) posee un programa cuyo objetivo principal es reforzar la coordinación entre diferentes países y así lograr el acceso generalizado de las poblaciones al agua potable, como así también lograr su uso responsable.
