Eukaryotic cells- contain membrane-bound organelles, including a nucleus.

• Phospholipids make up the basic structure of a cell membrane and are arranged in a double layer called the lipid bilayer.

• Active Transport- moves ions from low concentration to high, using metabolic energy in the form of ATP.

Select the correct answer from each drop-down menu.
gtnhenbr [62]

Answer:

1. Minimum viable population is the estimate of the fewest number of organisms a population needs to avoid extinction.

2. The measurement will most likely stay the same if the number of offspring each female in the population produces increases.

3. If the death rate increases, this measurement will most likely increase.

Explanation:

Minimum Viable Population:

  • Minimum viable population is an ecological threshold that signifies the minimum number of individuals required to prevent the species from going extinct.
  • MVP determines population conservation benchmarks.
  • MVP also helps in keeping a population genetically diverse as a limited number of individuals present limited mating opportunities and therefore limited genetic diversity.

The generation of a knock-out organism generally requires all the following EXCEPT ________. The generation of a knock-out organ
PilotLPTM [1.2K]

Answer:

knowledge of the sequence product

Explanation:

A gene knockout is a technique used in molecular genetics to deactivate target genes in an organism in order to study their functions by reverse genetics (i.e., gene loss). Knockouts are generated by different methods including, for example, homologous recombination or site-specific nucleases (zinc-fingers, TALENS, CRISPR/Cas9). These techniques require to know a priori the sequence of each gene to be knocked out in order to target desired mutations. In the last years, the CRISPR/Cas9 tool has gained attention to knockout genes of interest because it is a genome editing system that can be easily used for deletion or insertion of bases.
