Answer:

The correct answer is option A, Gastrula

Explanation:

Gastrula has three layers of cell and it is the phase in which single layered blastula matures and get converted into multilayered structure.  

However, Morula is formed after the formation of blastula through the process of blastulation. In the Morula phase, blastomers get arranged in a spherical shape after the zygote split. And zygote is formed at a very early stage of fertilization .

Thus  , gastrula is the correct answer as it is the stage which comes after zygote and morula and thus get developed into more compact mass of cells.

Answer:

The correct answer is option A, that is, gastrula.

Explanation:

The initial multicellular embryo comprising two or more germinal layers of cells from which the different organs are derived later is known as gastrula. The development of gastrula takes place from the hollow, solitary layered ball of cells known as a blastula that itself is the outcome of the cleavage of a fertilized egg.  

An adult multicellular species generally exhibit a concentric alignment of tissues of the body. These adult tissues are obtained from the three embryonic layers of cells known as germinal layers. The process of gastrulation comprises the reshuffling of the cells of the blastula into the three germinal layers, which later turns into different organ systems of the body of the organism.

How can colonies of organisms be produced by budding?
marissa [1.9K]
<span>Many species of sponges and the Hydra perform external budding. Cells will quickly divide within them and develop on the surface of the organism. These cells will form branches or extensions of the parent as they develop into a new organism.

Predict the most likely outcome of culturing transformed E. coli in the presence of tetracycline.Justify your prediction.
My name is Ann [436]

Answer:

E.coli is a bacterium which is preffered for transformation due to its rapid growth and high efficiency of introduction of DNA molecules into cells.

Tetracycline is an antibiotic used to treat several infections such as cholera, plague, brucellosis, and malaria etcetra.

Plasmid is a small, extrachromosomal DNA molecule present in cell which is seprated from chromosomal DNA and have ability to replicate independently.

When a plasmid resistant to tetracycline and kanamycine is inserted into E.coli, the process is called transformation. E.coli might not be able to survive due to absence of plasmid but the transformed strains having antibiotic tetracycline and kanamycine will probably be able to survive it.

Hence, the culture of bacteria carrying plasmid will be able to survive only.

How is a fish different from a jellyfish?
Korvikt [17]

Jellyfish are forever but fish ain't.

Plus, jellyfish have those tentacle like things attached to thier body and you might confuse em for octopus for that very reason..

but you should really evade confusing em as an octopus cuz octopus might take it as an insult and the next thing you know will be a Kraken taking your house down.. which is pretty tragic :'(
