Most of the nucleated cells in a multicellular organism contain all of the genetic information for the organism. Which of the fo
vova2212 [387]

<u>Answer</u>: Sperm cell

<u>Explanation</u>:

Amongst all the 4 options given, only the Sperm cell is a gamete (sex cell) while all the three are somatic cells.

  • A <em>somatic</em> cell is the one which forms the body of an organism and contains all the genetic information.
  • A <em>gamete</em> is the one which is required for the purpose of fertilization. A gamete of male fuses with the gamete of female in a process called fertilization to form a zygote to give rise to a new individual.
  • A Sperm cell is basically a <em>male gamete.</em> It contains only half the amount of genetic information as the other half is contributed by the female gamete.
  • This difference in the amount of genetic information arises due to the type of cell division that occurs. The somatic cells undergo mitosis whereas a gamete requires meiosis to occur for its formation.
  • During mitosis there is a single round of cell division which divides the parent cell into two daughter cells each with the <em>complete genetic information</em>.
  • During meiosis the cell undergoes two rounds of cell division such that a total lf 4 cells are produced each <em>with half the amount of genetic material </em>as present in the parent cell.

Since, <em>sperm is a male gamete and is formed by meiosis it contains only half the genetic information as compared to the other cells.</em>

andrew-mc [135]

Answer: Option A.

Achondrogenesis

Explanation:

Sonographic findings of severe micromelia, decreased or absent ossification of the spine, macrocephaly, and micrognathia are conditions of Achondrogenesis because

Achondrogenesis is a genetic disorder that is as a result of mutations in gene SLC26A2 which is responsible for cellular transport proteins that is needed for the growth and development of bones and cartilage. This condition lead to malformation of bones and cartilage and it is characterized by short limbs, small body, narrow chest ,prominent abdomen,underdeveloped lungs,lack of ossification in the spine and pelvis, prominent head, small chin e.t.c.

It is a condition that affects infants.

The major treatment is pallative care in which the doctor have to reduce pain stress of bones and cartilage and also genetic councellling.

xxMikexx [17]

Answer:

No.

Explanation:

I don't think it is fair that Watson and Crick were credited with the discovery when so many other scientists were involved because all other scientists also contributed in the work and work harder for it so the credit must be given to all scientists. If the credit will not given to other scientists so it is an unfair act so my opinion is against the credit given to Watson and Crick.

The bones of the skeleton have five major functions. Some bones protect soft body parts. For example, the sternum, thoracic vert
kirill115 [55]

Answer:

The sternum, thoracic vertebrae, and ribs protect the heart and lungs.

Explanation:

The skeleton can be divided into the <em>axial skeleton</em> (the skull and the vertebral column), <em>visceral skeleton</em> (ribs and sternum) and the <em>appendicular skeleton</em> (extremities).

The function of the <em><u>visceral skeleton</u></em> is to <em>support and protect</em> the first portion of the digestive and cardio-breathing apparatus.

In mammals, the second part of the vertebral column (thoracic vertebrae), the ribs and the sternum delimitate a protective box for lungs and heart.
