3 0

Answer:

motor (efferent)

Explanation:

The somatic nervous system is the component of the motor division of the peripheral nervous system. The motor division of the peripheral nervous system carries the motor information from the central nervous system to the muscles and/or glands. The motor branch includes the somatic and autonomic nervous system. The somatic nervous system of the motor branch delivers the motor information from the CNS to skeletal muscles resulting in the generation of voluntary responses such as raising hand in a class.

The Lac Operon is a set of genes that controls the production of lactase the enzyme that digests
Romashka [77]

Answer:

The lactose present prevents the production of lactase

Explanation:

This question is describing a set of genes in bacteria called LAC OPERON. Lac operon controls the production of lactase, which is the enzyme that digests lactose. However, this gene can be regulated at the transcription level i.e caused to be transcribed or not depending on certain factors.

According to the question, lac operon, which regulates the production of enzymes will be transcribed and subsequently translated i.e. turned on when there is a substrate (lactose) that the produced enzyme will work on. However, when there is no need of the lactase enzyme or there is absence of lactose (substrate), the lac operon gene is turned off.

Note that, the statement that "The presence of lactose prevents the production of lactase" is not correct.

Assume that you are a national official with the power to set policy for controlling environmental mercury pollution (Core Case
Kazeer [188]

Answer:

The policy for controlling environmental mercury pollution should address ways to prevent and control this pollution.  Policy:

  • Ban the incineration of waste
  • Require that coal-burning companies remove mercury from the coal
  • Allocate funds towards research and development for renewable energy resources in the hopes of switching away from coal.
  • Require that products containing mercury be labeled as such.
  • Set up programs that will recycle batteries and mercury-filled products.
  • Set up education programs that will help inform people about mercury pollution.

This policy works by addressing the ways to prevent and control mercury pollution.

Three problems that could result from implementing this policy:

  • Backlash from coal-burning companies.
  • It could take a while before we completely shift away from using coal.
  • Some of the programs that can be set up in this policy can be too expensive to set up and maintain.

Is race a biological characteristic determined by our genes?
Harman [31]

Answer:

No, they are not. The concept of human races appears to be solidly grounded in present-day biology and our evolutionary history. But if you asked that conference of geneticists to give you a genetic definition of race, they wouldn’t be able to do it. Human races are not natural genetic groups; they are socially constructed categories. Genes certainly reflect geography, but unlike geography, human genetic differences don't fall along obvious natural boundaries that might define races.
