Answer:
The correct option is cell wall and central vacuole.
Explanation:
The cell wall can be described as an additional membrane around the cell membrane which is present in the plant cells but is absent in animal cells.
The plant cells also have a vacuole located at the center on the cell. The central vacuole is absent in animal cells. It stores the waste and other materials for the plant cell. The plant vacuole also provides support to the cell.
Answer:
Sparse coding
Explanation:
Sparse coding can be described or explained as a situation where items are encoded or represented by strong activation of a relatively small sets of neurons.
It should be understood that neurons code for the intensity of stimulus , and this is done in two ways which are
* Frequency coding...here, the firing rate of sensory neurons increases with increased intensity, and
* Population coding....here, the number of primary afferent responding increases.
In this case, the results derived or gotten from both Arthur's and Roger's faces supported the sparse coding.
Answer: pollen
Explanation: The anthers bear the pollen grains which contains the male gamete(sperm).
Answer:
Protists are a diverse collection of organisms that do not fit into animal, plant, bacteria or fungi groups. While exceptions exist, they are primarily microscopic and made up of a single cell (unicellular), according to the educational website CK-12.
This is false. Organisms may play several important roles in an ecosystem. Consider for example and ocean shore environment occupied by a particular species of crab. The crabs are scavengers and eat any organic matter they encounter. They therefore play an important role in the cycling of nutrients in the ecosystem. The crabs are however also an important source of food for a range of other species occupying the same habitat, including octopi, certain fishes and sea otters. Therefore, the crabs are an important part of the food web in the ecosystem. Many species similarly occupy multiple important roles in an ecosystem.
