Answer:
Vacuole-Stores water and waste material.
This maintains turgidity in pants.It is large in size and occupies the center of palnt's cells.
Mitochondrion- Breaks down sugars.
This breaks down sugars during cellular respiration to produce energy as ATPs.
Lysosomes-Breaks down waste materials and debris.
This removes worn out cells and organelles.It is a vital organelle.
Ribosomes-Produces proteins for the cells.
This is the site of protein synthesis through translation of transcripted mRNA in the cells.
Explanation:
Answer:
B. bituminous
Explanation:
Bituminous coal is an organic sedimentary rock produced by compression of peat bog material by diagenesis and submetamorphics.
Bituminous coal has low moisture and high carbon content and hence used for the production of steel and cement, coke production an electricity generation.
Coking coal is a type of Bituminous coal are best used as fuel dource in metal industry having very narrow range of volatility and plasticity. Volatility is maintained by smelters to optimize the ease of burn rate, ignition, and energy output of the coal as this determines the burn rate of the coal.
Hence, the correct option is B. bituminous.

C.

Explanation:
Simple diffusion is pretty much exactly what it sounds like – molecules move down their gradients through the membrane. Molecules that practice simple diffusion must be small and nonpolar*, in order to pass through the membrane. Simple diffusion can be disrupted if the diffusion distance is increased. If the alveoli in our lungs fill with fluid (pulmonary edema), the distance the gases must travel increases, and their transport decreases. Facilitated diffusion is diffusion that is helped along (facilitated by) a membrane transport channel. These channels are glycoproteins (proteins with carbohydrates attached) that allow molecules to pass through the membrane. These channels are almost always specific for either a certain molecule or a certain type of molecule (i.e. an ion channel), and so they are tightly linked to certain physiologic functions. For example, one such transporter channel, GLUT4, is incredibly important in diabetes. GLUT4 is a glucose transporter found in fat and skeletal muscle. Insulin triggers GLUT4 to insert into the membranes of these cells so that glucose can be taken in from the blood. Since this is a passive mechanism, the amount of sugar entering our cells is proportional to how much sugar we consume, up to the point that all our channels are being used (saturation). In type II diabetes mellitus, cells do not respond as well to the presence of insulin, and so do not insert GLUT4 into their membranes. This can lead to soaring blood glucose levels which can cause heart disease, stroke, and kidney
Answer:
D.dragonfly larvae
Explanation:
For example ;
This is a simple food chain;
algae ⇒ mosquito larvae ⇒dragon fly larvae ⇒perch
Algae are the producers in the food chain above.
Mosquito larvae are the primary consumer in the above food chain.
Dragonfly larvae is the secondary consumer in the food chain which feed on the primary consumer.
The final level is perch, which is a carnivore .
