What are the factors that contributed to the success of pteridophyte as land plant
Anna35 [415]

Two factors contributed to the success of the pteridophytes: the extreme miniaturization of the gametophytic generation and an important development of the sporophytic generation (development of the tree forms).

Pteridophytes are a group of plants that peaked in the Carboniferous (-300 million years). It is the first great terrestrial plant civilization. These plants would have appeared in the Devonian -400 million years ago, perhaps from certain primitive terrestrial plants which, unlike bryophytes, would have favored the diploid generation on the haploid generation.

Particularly well adapted to terrestrial life, they have created, thanks to the development of tree forms, immense forests whose fossilization is at the origin of coal deposits.

Pteridophytes are at the origin of an evolutionary lineage based on the extreme miniaturization of gametophytic generation and an important development of sporophytic generation, leading to all tracheophytes including current flowering plants. Pteridophytes are well adapted to terrestrial life, however fertilization still requires the presence of water since male gametes are swimmers.

A student measured the mass and volume of a metal sample using a triple beam balance and a graduated cylinder. The sample has a
alexdok [17]

Answer:

d=3.79\ g/cm^3

Explanation:

Given that,

The mass of a sample, m = 16.7 grams

Volume of the sample, V = 4.4 cm³

We need to find the density of the metal sample.

Density = mass/volume

Substituting all the values,

d=\dfrac{16.7\ g}{4.4\ cm^3}\\\\=3.79\ g/cm^3

So, the density of the metal sample is 3.79\ g/cm^3.

Explain the production of monoclonal antibodies and give an example of how they are used.
taurus [48]

Answer:

Monoclonal antibodies (mAbs) are produced by introducing an antigen to a mouse and then fusing polyclonal B cells from the mouse's spleen to myeloma cells. The resulting hybridoma cells are cultured and continue to produce antibodies to the antigen.

Explanation:

An example of a monoclonal antibody is blinatumomab (Blincyto, Amgen), used to treat certain cancer, types of acute lymphocytic leukemia.

Leona [35]

The growth plate is the structure within a bone that contains cartilage cells that divide and increase the size of the bone until adult hood.

 

To add, the growth plate, also known as the epiphyseal plate or physis, is the area of growing tissue near the end of the long bones in children and adolescents.
