Answer:

1. Linear chromosomes with centromeres and telomeres that facilitate sexual reproduction

2. 3 dimensional DNA architecture to support control of transcription

3. Chromosome structure that controls packaging and expression.

Explanation:

The Eukaryotic genome is more complex and possesses a large number of base pairs compared to the prokaryotes.

The eukaryotic genome is arranged in a structure that they can be passed on easily to the offspring that is the linear DNA becomes condensed and form chromosome structure with a centromere is the center and telomeres at the end.

The chromosome structure allows the easy transcription of the genome and the controls the expression and packaging that is at some point it becomes condensed and at some it is relaxed.

Since the eukaryotes possess a membrane-bound nucleus, therefore, the option is incorrect.

Thus, the selected options are correct.

Anika [276]

Explanation:

B) protein channel

Lipids are composed of fatty acids which form the hydrobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which is water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backone) with up to 36 carbons.

Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. Via <em>diffusion,</em> small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Carrier proteins and channel proteins are the two major classes of membrane transport proteins.

  • Carrier proteins (also called carriers, permeases, or transporters) bind the specific solute to be transported and undergo a series of conformational changes to transfer the bound solute across the membrane. Transport proteins spanning the plasma membrane facilitate the movement of ions and other complex, polar molecules  which are typically prevented from moving across the membrane.
  • Channel proteins which are pores filled with water versus enabling charged molecules to diffuse across the membrane,  from regions of high concentration to regions of lower concentration. This is a passive part of facilitated diffusion

Ann [662]

Answer: Young children

Explanation: Resistance to food borne illnesses develops through exposure to small amounts of food borne pathogens. The longer the exposure, the greater the buildup of immunity. Young children are more likely to succumb to food borne illnesses due to lack of exposure to pathogens, and resultant lack of resistance to them.

In what way is, Chlorella, similar to a plant cell/ plant kingdom
vazorg [7]
Chlorella is a genus of about thirteen species of single-celled green algae belonging to the division Chlorophyta. The cells are spherical in shape, about 2 to 10 μm in diameter, and are without flagella. Their chloroplasts contain the green photosynthetic pigments chlorophyll-a and -b. In ideal conditions cells of Chlorella multiply rapidly, requiring only carbon dioxide, water, sunlight, and a small amount of minerals to reproduce.
