Explain how cellular respiration is the opposite reaction to photosynthesis.
Answer:
Cellular Respiration and Photosynthesis are almost opposite processes because photosynthesis removes carbon dioxide from the atmosphere while cellular respiration puts back carbon dioxide. Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2).

A. Where are the bronchi meet the bronchioles
B. Where the blood meets the cells
C. Where the nasal passages meet the air
D. Where are the alveoli meet capillaries
Answer:
The Answer is Option D.
Exchange of respiratory gases, oxygen and carbon dioxide take place in the alveoli of the lungs. Oxygen which is inhaled from the atmosphere diffuses through the walls of the alveoli and reaches to the adjacent capillaries into the red blood cells.

Explanation:
Complete question
Why?
Solution
The crops has extracted the nitrates from the soil for its nourishment and metabolic requirement. Hence, the concentration of nitrate after the crop cultivation has reduced as compared to the concentration of nitrate prior to the crop cultivation.

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.

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.

The GLUT transporter moves glucose through a transport protein in the same direction as its concentration gradient. The action of the glucose transporter is an example of _____________. The SGLT transporter uses the sodium concentration gradient created by the sodium potassium ATPase to move glucose against its concentration gradient. The action of the SGLT transporter is an example of _______________.
Answer:
The correct answer is - facilitated transport and secondary active transport.
Explanation:
GLUT transporter is a glucose transporter that helps in moving the glucose to its concentration gradient through the cell membrane. It is a transport protein that uses passive transport of facilitated transport that moves down their concentration gradient and therefore does not require chemical energy from ATP hydrolysis in the transport step.
Sodium-based GLUT or SGLT is also a glucose transport protein that exhibits secondary active transport as it develops electrochemical potential difference by moving ions out of the cell membrane, this gradient allows the movement of ions and molecules.

Why does having a genetically diverse population make a species more likely
to survive a change to the environment?
A. They are more likely to reach carrying capacity.
B. They are more likely to have harmful mutations.
C. They are more likely to become an invasive species.
D. They are more likely to have some individuals adapted for survival.
Answer:
D
Explanation:
Looks correct if you go with D
Genetically diverse population make a species more likely to survive a change to the environment because they are more likely to have some individuals adapted for survival. Thus, the correct option will be D.
What are Genetic variations?Genetic variation is the difference in the DNA molecule among different individuals or the differences between different populations of a species. The multiple sources of genetic variation include changes which could result from mutation and genetic recombination.
Mutations are the ultimate sources of genetic variation in a population, however other mechanisms, such as genetic drift, also contribute to it, as well. The populations which are genetically diverse are more likely to have some individuals adapted for survival.
Therefore, the correct option will be D.
