The semi fluid matrix that surrounds organelles in a cell is called the

Nitella [24]

The semi fluid matrix that surrounds organelles in a cell is called the cytoplasm.
Organelles are the specialized structure with in a cell. Some biologist says that organelle is a cell compartment. Mitochondria and plastids are two broad classes of organelles. Cytoplasm is a thick substance which fills each cell.

Nitrogen-fixing bacteria carry out the conversion of gaseous nitrogen to a biologically useful form of nitrogen
An energy pyramid illustrates that energy in the form of heat is lost to the surroundings as it is passed from one organism to the next
The energy role of a grizzly bear is that of a consumer because it cannot make its own food
Decomposers cycle nutrients from dead organisms back to the soil, where it becomes available for plants
The Savanna biome is characterized by its lack of trees, warm temperatures, and moderate rainfall

Explanation:

The nitrogen-fixing bacteria like Azotobacter which lives in symbiotic relationship in the rhizomes of leguminous plants. They convert inorganic atmospheric nitrogen gas through the action of its enzymes like nitrogenase to organic nitrogen in the form of ammonia, which is readily assimilated by the plants.
In an ecosystem, at each tropic level of an energy pyramid, only 10% of energy is utilized and transferred to the next higher tropic level whereas the majority of energy is dissipated as heat during various metabolic processes.
Decomposers also called saprophytes like earthworms, bacteria, fungi survives on dead and decayed remains of plants and animals and also on fertilizers, pesticides etc in the soil. They recycle the nutrients by breaking down the complex biomolecules into simpler forms and release back into the soil.
Grizzly bears being omnivores eat both plants and animals according to their availability. Hence they are both primary and secondary consumers.
Savanna is a grassland biome with a typical tropical wet and dry climate and receives moderate rainfall. Hence it cannot support trees but only have grasses.

he bodies of wild-type fruit flies are colored by dark pigments, but an X-linked recessive mutation can confer a yellow, unpigme

bekas [8.4K]

Answer:

We could feed them with another type of food free of silver salts.

Explanation:

When talking about a phenocopy, we are referring to individuals who genotypically should be expressing a determined phenotype, but due to environmental influence, they express another phenotype. This is a non-inheritable phenotype, so it is not considered a mutation.

If we grow thy flies feeding them another type of food that does not include silver salts, and let them mate and reproduce, they will express the real phenotype, because they will not be influenced by the food. In the following generation, there will be dark individuals carrying the dominant allele, and yellow individuals, with the recessive genotype.

Plants grow taller as a result of which of the following?

RSB [31]

I'm pretty sure it's primary growth. I might not have studied this type of biology yet, but secondary growth would definitely not be the answer.
