Answer:

The correct answer is - regulation of the heavy metal and their toxicity.

Explanation:

Metallothionein is a group of cysteine-rich, small in size, and highly conserved proteins that bind to various metal ions and regulate their activity or toxicity in transcriptional level.

Metallothionein IIA is one of the metallothioneins that binds to heavy metal and helps cells to be protected from the toxicity of these heavy metals. These proteins are present in almost every eukaryotic organisms virtually. These proteins are highly induced to express highly in the present of heavy metals.

Thus, the correct answer is - regulation of the heavy metal and their toxicity.

How does a virus cause disease?
nika2105 [10]

Answer:

Viruses are like hijackers. They invade living, normal cells and use those cells to multiply and produce other viruses like themselves. This can kill, damage, or change the cells and make you sick. Different viruses attack certain cells in your body such as your liver, respiratory system, or blood.

Explanation:

Viruses tend to target specific tissues (cells) in the host.

For example, the influenza virus has a predilection for the respiratory tract, hepatitis viruses target the liver, polio virus targets the motor neurons of the spinal cord and rotavirus multiplies in the gut. Symptoms of a viral infection may be subtle and nonspecific or specific and suggestive of the causative agent.

Dengue virus, Ross river virus, measles and rubella infections are associated with fever and a widespread red rash, chicken pox and herpes simplex viruses are associated with blistering, often localized, rashes; and hepatitis viruses cause liver damage and jaundice.

Bacteria tend to be less tissue-specific and non-discriminatory than viruses and can cause a variety of infections once they have invaded the host.

These bacterial infections are often manifested by the presence of pus wherever the bacteria settle, and systemic symptoms such as fevers, chills, pain, swelling and loss of function occur when bacteria invade and multiply.

A daughter cell that matures to the inside of the vascular cambium becomes ______, and a daughter cell that matures to the outsi
melomori [17]

A daughter cell that matures to the inside of the vascular cambium becomes<u> secondary xylem</u> and a daughter cell that matures to the outside of the vascular cambium becomes <u>secondary phloem.</u>

<u />

  • The cambium divides its cells to create secondary xylem and phloem. As secondary phloem and xylem tissue builds up, the stem becomes thicker and develops wood and bark.
  • The kind of xylem produced by secondary growth is known as secondary xylem. In contrast, during primary growth, the primary xylem develops.
  • As a result, lateral growth, as opposed to vertical growth, is connected with the secondary xylem, as opposed to the primary xylem.
  • The procambium, which is found between the xylem axis and the phloem pole, develops into the cambium in the root.
  • A pattern resembling the arrangement of secondary stem is produced when xylem forms in the core and phloem on the perimeter of secondary development.
