The action potential has three main stages: depolarization, repolarization, and hyperpolarization. Depolarization is caused when positively charged sodium ions rush into a neuron with the opening of voltage-gated sodium channels.
A. Adult stem cells is the correct answer.
The adult stem cells consist of rare mature tissues, which are limited to differentiating into different cell types of their tissue of origin.
Answer:
Observation
Curiosity
Determination
Explanation:
A biologist is a scientist that specializes in the study of biology or life generally. However, to become a successful biologist as stated in the question, the three mentioned characteristics needed are:
1. Observation- being an observer is key to becoming any scientist, including a biologist. Observation is the foundation of a scientific method i.e. it begins the process. Hence, a biologist must have good observation skills in order to thrive.
2. Curiosity- Curiosity refers to the ability to want to know what's going on. It's being inquisitive in order to learn new things. Asking questions is equally an important part of a scientific method as it determines the experiment. The question asked is what creates the experiment. Hence, being curious is a good quality for an intending biologist.
3. Determination: Being determined is not a quality only a biologist should possess. Determination is a must for any individual in any field. It is the ability to carry on irrespective of setbacks, which are inevitable.
Answer:
See the answer below
Explanation:
If the amount of light reaching a leaf and the water supply is adequate in the face of inadequate carbon dioxide, the <u>latter becomes a limiting reagent in the process of photosynthesis. </u>
The process of photosynthesis has two steps
1. The light reaction
2. The light-independent reaction/the Calvin cycle
<em>Carbon dioxide is only required in the second step which is the Calvin cycle. This means that the light reaction proceeds at a normal rate but the Calvin cycle is slowed due to inadequate carbon dioxide. Overall, the rate of photosynthesis becomes limited to the amount of carbon dioxide that is available in the leaf.</em>
