Answer:
The resting membrane potential is created and maintained due to the difference in the total charge or ions present outside and inside of the cell. The resting membrane potential depolarize if sodium come in and and potassium leaves the cell.
Explanation:
The resting membrane is maintained and created by the distribution of potassium and sodium ions. The membrane potential of a resting cell is -70mV (negative) because more sodium ions is present outside the cell than the potassium ions present inside the cell.
When the sodium ions enter inside the cell and potassium ions move outside the cell, the inside of the cell becomes more positive as compared to the outside and the membrane potential changes from -70 mV to +30 mV. The cells will depolarize due to the accumulation of sodium ions inside the cell.
Answer: Because glycogen is the storage form of glucose in animals and humans which is analogous to the starch in plants. Glycogen is synthesized and stored mainly in the liver and the muscles.
Explanation:
Answer:
Correct answer is A. "making future predictions about plant behavior "
Explanation:
The most important part of the question is "overcrowded area" which leads to the future concerned scenario of modern societies. We know that, in future, the supply of resources/nutrients will be limited and thus we want to develop sustainable practices. For this, scientists often carry out the experiments where the organisms are forced to live/grow in a crowded area and then we understand how each individual responds in the presence of limited resource supply. In this experiment, I perceive that the scientist is doing a similar kind of study for a specific plant which will help him assess the future concerns of growth and development for that species as well as its interaction with the environment.
<span>Independent variable: Time plants are watered (ex. 8am, 12pm, 4pm, 8pm, 12am)
Dependent variable: growth of the plant
Controlled variable: 1. same type plants, 2. same amount of sunlight, 3. same type of dirt, 4. same type of water, 5. same amount of water (each are self explanatory of how to control)</span>
No this is not valid, bacteria and other Arachae do not possess membrane bound organelles like mitochondria and or chloroplasts, but use transport and enzymatic proteins across the cell membrane to carry out essential functions.
Along with having polypeptide makers, as ribosomes.
