Answer: Option B) DNA polymerase

Explanation:

During DNA replication, semi-conservative replication for instance:

- a parent double-stranded DNA splits in two.

- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate replication of a newly synthesized strand

- the new strand contains nucleotides that are complimentary abd covalently bonded to free nucleotides present in the parent strand.

Thus, DNA polymerase is the answer

Definitive diagnosis of multiple myeloma includes the triad of bone marrow plasmacytosis, lytic bone lesions, and:_______
Ahat [919]

Answer:

Serum or urine components

Explanation:

Multiple myeloma is the cancer developed in the plasma cell that is a kind of white blood cell. The plasma cell helps in production of antibodies that protects the body from infection. Multiple myeloma causes the cancerous cells to aggregate in the bone marrow and covers the healthy cells.

The diagnosis of this type of cancer includes bone marrow biopsy, urine and blood tests. The bone marrow plasmocytosis includes the increase in plasma cells number in the bone marrow. The areas of bone damage that are due to cancerous plasma cell are the lytic bone lesions.

The proteins produced by the cancerous cells are detected in serum and urine samples. Thus, definitive diagnosis of multiple myeloma includes the triad of bone marrow plasmacytosis, lytic bone lesions, and <u>Serum</u>.

Readme [11.4K]

Answer: option "A" One seed develops from each ovule.

Explanation:

Ovules are the female reproductive part of the plant which is internally covered by the nucellus and integuments further helped in fertilization and development of seed.

After fertilization, ovule is the part of the plant develops into seed, after a period of time food tissue is developed inside it consisting the seed coats called integuments.

pollen grains or sperms are being transferred through the pollen tube to the embryo sacs from integuments only, which results into the fertilization and development of seed.

bulgar [2K]

Default network


When the brain is unoccupied, an fMRI indicates that blood continues to flow via a web of brain regions called the default network.

The default network is a web of brain regions that have activity that corresponds greatly with each other and different from other networks within the brain. The default network is active when an individual's attention is not concentrated on the external environment and it is measured with the functional magnetic resonance imaging technique (fMRI).

When plants make flowers, gene A is expressedin whorls 1 and 2, gene B is expressed in whorls 2 and 3 and gene C in whorls 3 and
Sati [7]

Answer:

The correct answer would be option D) no gametes.

Explanation:

The ABC model of the flower was formulated to describe the collection of genetic procedures that determines floral organs in several plants. These species consist of four whorls which are sepals, petals, stamens, and carpels. These whorls are expressed by the expression of a number of genes present in each whorl or verticli.

Gene A is solely responsible for the sepals while the co-expression of A and B genes are responsible for the petals. The identity of the stamens is expressed by B and C and the carpels require C and D genes to be active.

The homozygousity for a normal mutation in gene C will lead to inactive or lack stamens and carpels, which are male and female reproductive organs. These are an important structure for forming gametes.

Thus, the correct answer would be option D) no gametes.
