Answer:

A) They form chemical bonds with other atoms

Explanation:

In chemistry, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.

1. Archaea are prokaryotic cells. These are one of the two prokaryotic organism domain. the other is eubacteria.

2. Eubacteria cell wall contains peptidoglycan which is composed of sugar and amino acids.

3. Eukaryotic cells have membrane-bound nucleus or organelles. which distinguishes it from prokaryotic cells.

4. All archaea domain organisms found in extreme conditions such as halophiles, extremophiles, and thermophile.

5. The cell wall of the plant is made of cellulose, a polymer of glucose units.

6. Eubacteria are considered to be the first living organism or form found on earth.

7. Fungi cell walls are made up of a chitin cell wall. which is makes it different from eubacteria and plants.

8. Fungi uses absorption to obtain nutrients. Most of the fungi uses haustaurium to absorb nutrients.

9.Fungi are organism that do not fit in other eukaryotic category. Hence they were classified as separate kingdom in 5 kingdom classification.

10.plants are classifies as autotrophs because they make their own food.These autotrophs serve as primary producers.

11.Corals have a symbiotic relationship with algae. Algae provide food for coral through photosynthesis where as coral provide protection to algae.

12.corals are classified as autotrophs due to their relationship with algae.They are mixotrophs generally because they act as autotrophs with association of algae and capture prey by tentacles thus making heterotrophic nutrition.

Where do the axons that enter the cortico-spinal tract originate? (The complete answer should include more than one of Brodmann’
torisob [31]

Answer:

<u>From the main motor cortex, Brodmann region 4 premotor areas and the primary somatosensory cortex .</u>

<u />

Explanation:

The corticospinal tract originates in many regions of the brain, including

  • the motor regions,
  • main somatosensory cortex
  • pre-motor regions

The corticospinal tract allows for voluntary control of motor functions.

30% of the neurons in the corticospinal regions are found in the primary motor cortex. 40% are split up in several regions; the parietal lobe, somatosensory cortex and the cingulate gyrus.

The axon is a tube enclosed in and insulated by the myelin sheath. It serves as a link to impulses for certain neurons that often comprise axon hillocks that are junctions between the axon and the cell body.
