Which structures that distinguish a eukaryotic cell from a prokaryotic cell are part of the internal membrane system?
Nat2105 [25]

Answer:

nuclear membrane, endoplasmic reticulum, Golgi apparatus, and vesicle

Explanation:

The structures or organelles in internal membrane system in the cell do all production, processing and secretion function together. A prokaryotic cell does not contain any membrane bound organelles but Eukaryotic cells do have. Nuclear membrane has double membrane and golgi-rendoplasmic reticulum and vesicle contain single membrane so all these organelles are membrane bounded.

If one strand of a DNA molecule has the sequence of bases 5′-ATTGCA-3′, the mRNA synthesized following the template will be ____
rjkz [21]

If one strand of a DNA molecule has the sequence of bases 5-ATTGCA-3, the mRNA synthesized following the template will be 3-UAACGU-5.

Nucleotides are added to the growing strand one at a time in the precise sequence dictated by the existing  template strand. adenine and thymine are always paired with each other in the Watson-Crick DNA model, and cytosine is always paired with guanine.

The nucleotide sequence of DNA serves as a template for the nucleus, where mRNA is synthesised. The RNA polymerase II enzyme is responsible for this reaction's catalysis and needs nucleotide triphosphates as its substrates. Transcription is what happens in the nucleus when DNA is converted into mRNA. The cytoplasmic synthesis of proteins is controlled by the mRNA. The cytoplasm is where the mRNA that is produced in the nucleus attaches to the ribosomes after being transported from the nucleus. The nucleotide sequence of the mRNA serves as a guide for the assembly of proteins on ribosomes. The cytoplasm receives a "message" from the nucleus via mRNA. The nucleotide sequence of the mRNA, which is complementary to the nucleotide sequence of the messenger RNA, encodes the message.

c disruption of animal habitats

Explanation:

One of the likely effect of large scale infrastructural development is that it can lead to the disruption of animal habitats.

To develop new infrastructure, new areas have to be cleared to install the facilities and this can lead into encroachment of animal habitats.

  • Oil drilling projects are capital intensive ventures undertaken by exploration and production companies.
  • The oil is usually found in geologic formations deep within the earth crust.
  • To access this fuel, large drilling ventures must be undertaken in order to accommodate to technology and man power.
  • New areas have to cleared and this can push the habitat of organisms backward
