<span>TESTING HYPOTHESIS ABOUT INDIVIDUAL REGRESSION COEFFICIENTS: t STATISTIC) : The t statistic. Used to determine which of the independent variables influences the dependent variable. Whether a particular independent variable influences the dependent variable Test whether the true value of the parameter estimate is zero. The higher the value of the t-statistic, the smaller the value of the regression coefficient is zero.</span>

Piensa por lo menos dos ejemplos para cada tipo de noxa Biológicas: Físicas: Químicas: Psicosociales
Neko [114]

Answer:

A noxa is any component of the natural context, with the ability to generate some harm to the person who touches it.

Explanation:

Any blow with mechanical damage, change in temperature or pressure, UV radiation, plutonium, strontium, X-rays, electricity, loud noises is considered physical noxa.

Examples of this can be: Physical hazards: noise, radiation (ultraviolet, x-rays), electricity, blows, breaks, burns, cuts.

Chemical noxa is toxic and poisons, mostly of exogenous origin, that enter the body accidentally.

Examples of this can be: Chemical noxes: insecticides, pesticides, poisons, toxic gases, co2, co.

Biological noxas are living beings or viruses recognized as pathogenic agents, since they cause diseases of varying symptoms, evolution and severity, but which are called infectious diseases.

Examples of this can be: bacteria, protozoa, fungi and non-cellular entities, such as viruses.

Psychosocial noxas are actions or lack of actions that can cause mental disorders and that can lead to physical problems. Its impact is often negative on general well-being, particularly for young people.

Examples of this can be wars, racism or bullying.

Hey can someone please help with this ap bio question.

Answer:

a) Individual 1

b) Overall, the higher the number of mutant alleles, the greater is the concentration of cysteine in urine relative to normal values.

c) The hypothesis may be correct. If number of mutant allele in SLC7A9 is higher than number of mutant allele in SLC3A1, then concentration of cysteine  in urine is lower. This means that transportation of cysteine is affected by a greater extent if mutant allele in present in SLC7A9 genetic sequence

d) concentration of cysteine is affected by mutant allele which is a complex protien. If complex protien is low cysteine is not transported back and its concentration in urine is higher

Explanation:

a) Can be inferred easily from table. Higher the mutant allel that is negative, higher is the concentration of cysteine. Hence greater the chances of cystinuria.

b) As explained in part a

c) Observe the pattern on concentration of cycteine and number of - allele. If cysteine is not transported back then its concentration in urine will be higher.

d) The complex protien helps in transportatino of cysteine by binding to it. In the absence of the ocmplex protien, cysteine tends to behave like polar molecule and stay in water that is in excess in urine.
