The most likely unit for measuring the size of a typical mature yeast cell is micrometer. Micrometer (μm) or micron is unit of length which is 10⁶ times smaller than meter. Yeast cells are very small, usually yeast cells are 3-4 μm, but some species can reach size of 40 <span>μm.</span>
<h3><u>Answer;</u></h3>
d. a neuron recharges before it can fire again.
<h3><u>Explanation;</u></h3>
- <em><u>Refractory periods are a short phase in time following an action potential where another action potential cannot be generated. </u></em>
- <em><u>It is the period immediately following the transmission of an impulse in nerve or muscle, in which a neuron or muscle cell regains its ability to transmit another impulse. </u></em>
- There are two types of refractory period, that is the absolute refractory period and the relative refractory period. Absolute refractory period is the first part of a refractory period during which, the neuron will not fire again no matter how great the stimulation and this only lasts for a short time.
- Relative refractory period occurs when a stronger than usual stimulus is required to trigger the action potential before the neuron returns to resting state.
Habitats outside the preserve area become damaged by overdevelopment.
Answer:
The correct answer is ''They are all vascular plants''.
Explanation:
Vascular plants or tracheophytes are those organisms of a more evolved plant nature, they are those that have leaves, stem and roots and that have a vascular system formed by conducting vessels. Ferns are pteridophytic vascular plants, they do not produce flowers or seeds and are mostly herbaceous. All those vascular plants that have seeds but do not have flowers are called gymnosperms. The seeds are not covered or protected by an ovary, so they appear visible on the leaves or other parts of the plant. Angiosperms are plants with flowers, whose seeds develop within the ovary, which grows and becomes fruit.
