1 answer:
Natali [406]2 years ago
3 0

Answer:

The statement is true.

Explanation:

When a chemical substance is dangerous for people's health, we speak of a toxic risk. This risk can materialize if exposure to the chemical agent is not controlled. Toxic substances are those substances capable of causing harmful effects in a living organism when they come into contact with it or when ingested,  intentionally, accidentally, or deliberately. The toxic risk of a chemical product depends on two factors: the toxicity and the absorbed dose, where a series of factors influence: composition, properties, concentration, duration of exposure, route of entry into the organism and workload.

Independent assortment of chromosomes is a result of _____.
Ann [662]

Answer:

the "second law of Mendel", or principle of independent distribution, states that during the formation of gametes, each pair of alleles segregates independently of the other pairs.

Explanation:

Mendel's second Law is also known as the Law of Segregation, also as the Law of Equitable Separation, and also as the Law of Disjunction of the Alleles. This Second Law of Mendel is fulfilled in the second filial generation, that is to say, from the parents to the first generation, the First Law of Mendel is fulfilled, and after the children of the first generation this Second Law of Mendel is fulfilled.

This 2nd Law of Mendel, speaks of the separation of the alleles in each of the crossing between the members of the first generation, who would now become parental of the second generation, for the formation of a new child gamete with certain characteristics.

Since each allele is separated to constitute features that do not belong to the first filial generation, but to that of the parents. That is to say that many of the most obvious features in the recessive allele would be present when a generation leaps. All this in relative proportion to the number of individuals in the second subsidiary generation.

How many cycles of oscillation does the radiation from a cesium-133 atom complete during one mosquito wing beat?.
kondaur [170]

The frequency of radiation from a Cesium-133 atom is 9,192,631,770 cycle/s

= 9.192631770×10^{9} cycles/s

The number of cycles of radiation in one second is 9.192631770×10^{9}

The number of cycles during 1 mosquito wing beat,

i.e., the number of cycles in \frac{1}{605} s

= (9.192631770×10^{9})(\frac{1}{605} )

= 1.519×10^{7} cycles/beat
