There are some environmental factors of which organisms
respond to in order to maintain balance in its course of life, the factors or
stimuli that they respond to are the following, weather, temperature, air,
water and other organisms living in the area or other areas.
Answer:
yes, it is correct because ik that it's B
Explanation:
it is
Yeast fermentation produces ethanol and carbon dioxide.
- Fermentation is an anaerobic pathway that breaks down glucose in absence of oxygen.
- Conversely, cellular respiration requires oxygen to break down glucose molecules.
- Fermentation is energetically less efficient than cellular respiration in terms of the generation of energy (ATP).
In conclusion, yeast fermentation produces ethanol and carbon dioxide.

Answer:
The correct answer is C) Passive transport
Explanation:
During the respiration process exchange of gases takes place between lungs and blood. This gas exchange is carried by simple diffusion which is a passive transport. Here gas molecule moves from area of higher concentration to the lower concentration area.
The lung's alveoli are surrounded by blood capillaries in which the concentration of CO2 is high while in alveoli concentration or partial pressure of CO2 is low so CO2 moves from blood to alveoli through diffusion.
In the case of oxygen, the concentration of oxygen is high in alveoli and less in blood inside blood capillaries so oxygen moves from alveoli to blood by diffusion. So the right answer is C.
Answer:
<h2>EGFR will activate other proteins without dimerization, causing uncontrolled cell growth.</h2>
Explanation:
EGFR gene
:
Epidermal growth factor receptor,
-which spans the cell membrane so that one end of the protein remains inside the cell and the other end located outer surface of the cell. This causes receptor to attach ligands, and to receive signals ,by which cell respond to its environment. Epidermal growth factor receptor binds to many different type of receptors. The binding of a ligand to receptor allows the receptor to attach to another nearby epidermal growth factor receptor protein (dimerize), activating the receptor complex. As a result, signaling pathways within the cell are triggered that promote cell growth and division and cell survival. If there is abnormlty in the expression of EGFR gene , then the cell show uncontrolled growth.
