A is the Stigma and B is the Style
The stigma is part of a pistil Where pollen germinates and it provides receptacle pollen
The style is is where pollen deposits
Answer:
Sea stars carry out life functions in diverse -and unique- ways (<em>read below</em>) and are able to respond to environmental changes through adaptations such as temperature regulation.
Explanation:
Sea stars are invertebrate organisms that belong to the Phylum Echinodermata and are adapted to life in the ocean. They carry out life functions in diverse kind of ways. Here are some examples:
- <u>Limb regeneration</u>: they are known for the impressive ability to regenerate their limbs, which they accomplish because almost all of their vital organs are located in the arms.
- <u>Feeding</u>: sea stars are generally carnivorous creatures. They use their suction-cupped feet to open clams, mussels, and oysters. On the other hand, there are some species that prefer to feed on detritus or organic matter.
- <u>Locomotion</u>: these organisms are able to move thanks to their water vascular system, as they do not possess a circulatory system. Water circulates throughout their body into their feet, allowing it to extend and move.
Response to environmental changes:
According to new research evidence, these marine creatures possess unique adaptations that are extremely helpful in regard to environmental changes. They are able to regulate their own temperature during changing tides. During high tides, sea stars absorb cold water that is later used when temperatures are too hot due to warm water and sunlight. This adaptation is crucial to respond to environmental changes such as climate change.
I think the correct answer is ions.
An action potential occurs when a neuron sends information down an axon, away from the cell body. A neuron that emits an action potential, or nerve impulse is said to fire. These action potentials are generated by special types of voltage hated ion channels that are embedded in the plasma membrane of the cell.
Water enter and leaves the cell by osmosis, which is a specific example of diffusion. <span />
