Cell structure and transport is described below.

Explanation:

  • The endomembrane system includes the nuclear envelope, the endoplasmic reticulum, Golgi apparatus, lysosomes, vesicles, as well as the plasma membrane. These cellular components work together to modify, package, tag, and transport membrane lipids and proteins.
  • The cellular structure that was visible in the transmission electron micro graph but not visible in the cells when microscope was used is NUCLEOLUS.The cell membrane is a protective barrier that regulates what enters and leaves the cell.
  • Correctly folded and assembled proteins in the ER are packaged into COPII-coated transport vesicles that pinch off from the ER membrane. ... The Golgi apparatus distributes the many proteins and lipids that it receives from the ER and then modifies the plasma membrane, lysosomes, and secretory vesicles.
  • The Golgi apparatus receives proteins and lipids (fats) from the rough endoplasmic reticulum. It modifies some of them and sorts, concentrates and packs them into sealed droplets called vesicles.

BaLLatris [955]

Answer:

Daisy's episodic memory is impaired, but her semantic memory is intact.

Explanation:

Episodic memory is the type of memory that holds events experienced by the person. That is, it is the memory that holds the places the person went, important dates, events that occurred and other things that the patient was present at the moment. If Daisy can't remember what she did last week, how the accident happened, or any of her childhood experiences, then her episodic memory is compromised.

Semantic memory allows humans to communicate with language. In semantic memory, the brain stores information about words, what they look and represent, and how they are used in an organized manner. Daisy is able to read, write and speak accurately and remember the names of countries, things, places and famous people, that means her semantic memory is intact.

Cyclopropane is a highly strained molecule. why? select all that apply.
aleksley [76]

Cyclopropane is a highly strained molecule because the conformations of the cycloalkanes are influenced by the torsional, angle strain, and steric strain. Cycloalkanes, which comprises more than three atoms of carbons are not flat molecules, they are puckered.  

The three and four-membered ring components exhibit angle strain and minimize the internal bond angles. The angle strain is generated when the bond angles deviate from the optimum tetrahedral angle, that is, 109.5 degree.  

Torsional strain is a resultant of eclipsing interactions, and steric strain is attained when the atoms are forced too close to each other.

ANTONII [103]
Carbohydrates are examples of food types or biomolecule utilised by living organisms to acquire energy amon other functions. They are classified into monosaccharides, disaccharides and polysaccharides. Polysacchrides conatin multiple monosaccharides joined together by bonds forming a long chain and a complex molecule, for example, chitin, cellulose and peptidoglycan. These polysaccharides exists as a set of long, parallel strand that are linked to one another, a feature that makes them act a structural molecules withstanding pulling and pushing forces well.

andrew-mc [135]

The missing part of the question is -

" Is this Primary or Secondary Succession?"

Answer:

The correct answer is - secondary succession.

Explanation:

Recolonization of the plant and animals to habitat after a major disturbance such as flood, lava eruption, wildfire, or human disturbance is characterized as secondary succession.

In this particular case, there is secondary succession occurs, there is man-made disturbance tajes place as logging company clear the spruce trees from a habitat, and after clearing the land the spruce seedlings began to sprout, birds, rabbits recolonize to the area.
