spayn [35]3 years ago

Answer:

External fertilization usually occurs in aquatic environments where both eggs and sperm are released into the water Most external fertilization happens during the process of spawning where one or several females release their eggs and the male(s) release sperm in the same area, at the same time.
Typically, frogs lay eggs. This process usually occurs through external fertilization, where the female releases her eggs from her body into water. Then, the male releases his sperm to fertilize them In this case, the eggs are fertilized inside the female's body before they are released.

aksik [14]

Answer:

A) Brain genomic library and muscle genomic library.

B) Brain genomic library and muscle genomic library - overlap completely.

Human brain cDNA library, and a human muscle cDNA library and other library is partially overlap.

Explanation:

A) The genomic library contains the whole genome content of the organism whereas cDNA library contains the coding genome of the organisms. Brain genomic library and muscle genomic library will constitute the all the genomic sequences of brain and muscle.  The cDNA library is prepared from the mRNA and the coding regions are present in this library.

B) The overlapping in the genome library might occur due to the common sequences present in the genome. Brain genomic library and muscle genomic library might completely overlap with each other as they have more sequence common among each other. All the other library may be partially overlap with each other as they have some common DNA sequences and neither library can have unique sequences.

How would you calculate density for a cubic solid ?
mel-nik [20]
You are given the mass of the metal block, but you must calculate its volume using the measurements of the given dimensions. For a rectangular solid, volume = length x width x height; therefore, the volume of the block is (3 cm)(5 cm)(4 cm) or 60 cubic centimeters. The density is 14 g/60 cc or 0.23 g/cc.
