What statement correctly describes the relationship among endocrine glands, target cells, water-soluble hormones, and lipid-solu
9966 [12]

Water-soluble and lipid-soluble hormones that bind to target cells are secreted by endocrine glands.

The interaction between endocrine glands, target cells, water-soluble hormones, and lipid-soluble hormones is accurately described by the aforementioned sentence.

<h3>What functions and how does the endocrine system operate?</h3>

The level of hormones in your blood is regularly monitored by your endocrine system. In order to transmit the message, hormones send their messages by locking into the cells they intend to reach.

When your hormone levels increase, the pituitary gland signals other glands to stop manufacturing and releasing hormones. The pituitary gland has the ability to tell other glands to manufacture and release additional hormone when levels fall below a certain threshold.

Homeostasis is a process that functions similarly to your home's thermostat. Almost every physiological process is impacted by hormones, including:

  • Metabolism
  • Growth & development.
  • Emotions & mood.
  • Fertility & sexual function.
  • Sleep.
  • Blood pressure.

a culture of e. coli is irradiated with uv light. the highest frequency of mutations would be obtained if after the irradiation,
Klio2033 [76]

Oftentimes UV light can cause the genetic code of an organism to mutate, leading to a variety of errors, some of which are not compatible with life.

UV light is considered to be a mutagen. What this means is that the exposure of cells to UV light often leads directly to a mutation in the genetic code of that cell. This correlation has been studied extensively and shown to affect the nucleotides of DNA, which are:

  • A base (adenine)
  • T base (thymine)
  • G base (guanine)
  • C base (cytosine)

The exposure to UV light causes the base nucleotides in the DNA of an organism to oxidize. This oxidization causes the base pairs to form dimers. Most often the dimer formed is of a <u>thymine base</u>. This can be thought of as the fusion between two thymine bases, which will alter the frame in which DNA is read and <u>cause all sorts of abnormalities</u>.
