Answer:
En física, la fuerza es una magnitud vectorial que mide la intensidad del intercambio de momento lineal entre dos cuerpos. ... La unidad de medida de fuerza es el newton que se representa con el símbolo: N, nombrada así en reconocimiento a Isaac Newton por su aportación a la física.
Explanation:
Answer:
a. Oxygen performs an essential role in the mentioned microbial cell in a manner that it takes part in the procedure of glycolysis, Krebs cycle, and electron transport chain, which eventually assists in the production of energy from food substrates and this generation of energy helps the cell to survive.
In the existence of oxygen, sugar gets dissociated through glycolysis to generate pyruvate, which again in the existence of oxygen is transformed into acetyl CoA. This moves into the Krebs cycle and gets dissociated to water and carbon dioxide generating ATP through ETC. This generation of ATP helps the cell to survive.
In low oxygen surrounding or in the absence of oxygen, some of the aerobic microbes can switch their respiratory pathway and carry on the process of fermentation and anaerobic respiration to produce energy and thrive. However, the mentioned microbial cell, which when it comes in contact with the low oxygen environment cannot carry out fermentation process and would die eventually.
b. This organism can be classified as obligate aerobes as they always need oxygen and do not possess the tendency to carry out the process of anaerobic respiration or fermentation under the absence of oxygenic environment.
The significance of carbon having four valence electrons is so that its outermost shell can form up to four covalent bonds.
CARBON AS AN ELEMENT:
- Carbon is an element with atomic number 6 on the periodic table. It belongs to group four. Carbon is said to be a unique element because its properties.
- One of those properties is its ability to form four covalent bonds with other atoms including itself.
- Carbon posseses four valence electrons and is ready to share each in a covalent bond with other atoms so that it can fill up its outermost shell.
Therefore, the significance of carbon having four valence electrons is so that its outermost shell can form up to four covalent bonds.

Organelles, such as mitochondria
Answer:
The correct answer is - B. The seeds are in berries that are eaten by birds and dropped as waste away from the plant.
Explanation:
The mountain ash trees contain red berries fruits that attract birds and other organisms. These birds eat these berries and eat berries and fly over the hills or mountains and after digesting they drop the seeds of these berries with the digestive waste. These berries grow on the mountains far from the original source as birds carry them by flying away after eating.
Thus, the correct answer is option B.
