Answer:
Skin, Kidneys, And Lungs
Explanation:
Excretion is the removal of toxic materials, waste products of metabolism and excess substances from organisms. Egestion is the passing out of undigested food as faeces, through the anus. Three major organs of excretion are the skin, kidneys and lungs. Sweat glands in the skin produce sweat.

Answer: Enzymes are incredibly versatile, each catalyzing a huge number of biological reactions.
An enzyme behaves like both a heterogeneous and a homogeneous catalyst.
Explanation:
Enzymes are the biological catalyst they speed up the rate of the reaction without being consumed in the reaction. It is versatile in terms of catalyzing huge number of biological reactions but every enzyme has a specificity for a reactant or substrate. An enzyme can work as both homogenous and heterogenous catalyst. Homogenous catalyst is the one which is similar in properties as that of the substrate and heterogenous catalyst is the one which is dissimilar in properties as that of the substrate.
The correct characteristics is that of the action of an enzyme, enzymes are enormously efficient, much more so than synthetic catalysts.
Uses of enzymesEnzymes are biological substances that has the ability to increase the rate of a chemical reaction without changing at the end of the reaction.
The features of an enzyme include:
They possess great catalytic power and a small amount can easily catalyze a chemical reaction.They speed up reactions but remain unchanged during the whole reaction.There are synthetic and biological enzymes. The biological enzymes are enormously efficient, much more so than synthetic catalysts because biological enzymes has more affinity for its substrate than the synthetic enzymes.

Which statement best explains why herbivores are not considered parasites
Answer:
Hello There!!
Explanation:
The answer is=>Parasite means that the organism must live inside (intracellular) or on the outside body of the organism (extracellular). The herbivores do not live on the host (plants) for its survival. They just eat the plants and fruits for getting energy. Therefore, the herbivores cannot be called as parasite.

gymnosperms is an advance ground than pteridophytes ? justify
Both gymnosperms and pteridophytes are groups of plants that evolved before the appearance of flowering plants (angiosperms).
While it is difficult to definitively categorize one group as being more advanced than the other, there are certain characteristics of gymnosperms that are considered more advanced compared to pteridophytes.
Here are a few reasons why gymnosperms are often considered more advanced:
1. Reproductive Structures: Gymnosperms have advanced reproductive structures compared to pteridophytes. Gymnosperms produce seeds, which are protected structures containing the embryo plant and a food source, allowing for successful dispersal and germination.
Pteridophytes, on the other hand, reproduce through spores, which are more vulnerable and have lower survival rates compared to seeds.
2. Pollination: Gymnosperms typically have more advanced pollination mechanisms. They often rely on wind or animals for pollination, whereas pteridophytes primarily depend on wind for spore dispersal.
The use of animals for pollination, such as insects or birds, is considered more advanced as it allows for a more precise and efficient transfer of pollen.
3. Vascular Tissue: Both gymnosperms and pteridophytes have vascular tissue (xylem and phloem) for the transport of water, nutrients, and sugars. However, gymnosperms have more efficient vascular systems, allowing for better nutrient and water uptake.
This increased efficiency is attributed to the evolution of specialized conducting cells called tracheids, which are more advanced than the conducting cells found in pteridophytes.
4. Adaptability: Gymnosperms exhibit a wider range of adaptability compared to pteridophytes. They can thrive in diverse habitats, including harsh and cold environments.
Gymnosperms have evolved various adaptive features, such as needle-shaped leaves, thick cuticles, and reduced leaf surface area, which helps reduce water loss and increase tolerance to extreme conditions.

Depletion of nonrenewable resources is often a result of:
1)environmental laws
2)human population growth
3)reforestation
4)recycling
Answer:
Depletion of nonrenewable resources is often a result of reforestation.
Answer:
2 -- Human Population Growth
Explanation:
The rest have no effect on nonrenewable resources because they are renewable, or replenishable. The more humans expand, they more resources they need such as gas, coal, and oil. Due to the fact that resources such as those listed before can't be renewed, or replenished, it causes a loss in those resources (depletion).

Why do some ecosystems remain stable for centuries while others undergo succession
As long as the ecosystem inputs remain the same, the ecosystem will remain stable. Only when there is a fire, drought, or other disturbance in the ecosystem, will the ecosystem change. A new set of plants will arise to most efficiently use the resources that are available under the new conditions. However, over time, if the disturbance is temporary, the ecosystem will eventually revert to the stable ecosystem that was there before the disturbance.
What is a stable ecosystem?Stability (of an ecosystem) refers to the capability of a natural system to apply self—regulating mechanisms so as to return to a steady state after an outside disturbance.
What is succession?Ecological succession is the process of change in the species structure of an ecological community over time.
Causes of succession:Topographical: Extreme conditions cause abiotic topographical factors, which are mainly involved with secondary succession. Landslides and mudslides are examples of this type of factor.Soil: The soil, an abiotic factor, of an environment affects ecological primary succession greatly. Different species of plants require different soil conditions.Climate: Climate, an abiotic factor highly involved in both primary and secondary succession, plays a significant role in determining the direction of succession in an environment. Ecosystem remains stable: It’s all about balance, left to its own devises nature constantly rebalances.populations increase and decrease all the time, usually due to food sources either being plentiful or scarce, when plentiful the animals that feed on them thrive and breed.when scarce they starve and decline in number, this decline in numbers allows time for the food source to regrow or reproduce (if the food source is another animal species), The ecosystem is unaffected in the long run and remains in balance.Thus, it can be concluded that As long as the ecosystem inputs remain the same, the ecosystem will remain stable.
