<h2>Membrane potential </h2>
Explanation:
- Membrane potential represents charge difference across the membrane, all biological cells are negative inside (cytoplasm) and positive outside (due to difference in ionic distribution)
- In a typical neuron cell membrane potential of cytoplasm is negative at rest (when no stimulus is applied) hence called resting membrane potential
- Resting membrane potential of excitable cells is established by Na+ and K+pump
- Repolarization starts with the efflux of K+ by the opening of voltage gated K+ channels
- Voltage gated K+ channels starts to open when voltage gated Na+ channels becomes inactive
- Hyperpolarization occurs due to excessive efflux of K+ by voltage gated K+ channels
- Additional efflux of K+ occurs due to slow inactivation of voltage gated K+ channels
The answer is “it is the gap between neurons” and “it ensures that information travels in one direction only.”
This would be 7. Below 7 is acidic and above is basic. 7 is neutral
The complete statement is this: CNIDARIA exhibit two radial body forms, the polyp and the medusa, and use stinging cells to capture prey.
Cnidaria is categorized under the Animalia kingdom. It is made up of more that eleven thousand species, which all live in aquatic habitats; either fresh or salt water environments. There are four basic classes of cnidarians, these are: Anthozoa, Cubozoa, Scyphozoan and Hydrozoa. Their common feature is the cnidocytes, which are specialized cells that they use to capture their preys.
Cnidaria have two radial body types, which are called polyp and medusa. They used cnidocytes (stinging cells) to capture the foods they feed on.
Answer: A: Pine, Cedar and Mango.
B: Pine and Cedar
C: Mango, Cedar and Elm
D: Pine and Cedar
Explanation: Evergreens plants always have there leaves on regardless of the season, because their roots go very deep into the soil getting water and nutrients far below the levels other tap roots can go, they are mainly found in the rain forest region that have abundance of water. Example, Mango
Deciduous trees are usually found at desert places that dont always have water, so they lose their leaves during etreme weather to reduce the rate of evaporation of water on its surface. Example, Maple.
Hardwood: These are flowering plants. they usually have broad leaves and nuts. example, Mahogany.
Conifers: These are cone bearing seed plants. they are perennial and woody plants. Example Pine.
