Answer:
its human activity that change ecosystems
Ecosystem survival during earth change is helped by biodiversity, which produces a quality environment, hence option b is correct.
What factors affect the ecosystem?Ecosystem drivers encompass both natural and human-made elements. For example, habitat change and over-exploitation are direct causes that overtly affect ecological processes.
The effects of human activities on land and in the sea may have a significant impact on ecosystems. Among the various issues that ecosystems face include climate change and ocean acidification.
Biodiversity produces a quality of the environment that combine with oxygen, clean air, and water, pollinates plants, controls pests, treats sewage, and provides a wide range of other ecosystem services.
Therefore biodiversity provides an environment for the ecosystem when the earth changes, hence option b is correct.

The decline in approximately 70% of the world’s bird species is particularly alarming to scientists because ____ .
Answer:
See the answer below
Explanation:
The approximately 70% decline in the world's bird species is alarming to scientists because some species of birds have been found to be good indicators of the health status of the environment. Birds are generally easy to detect in an environment and the ability to fly away due to terrible conditions of habitat makes them a good indicator of the health of habitats or environment in general.
A 70% reduction in the species of birds worldwide is thus alarming due to the direct correlation that exists between the species diversity of birds and the health of the environment. It could presumably be an indication that about 70% of the world's habitat has been destroyed or impacted negatively.
three sentences about the role termites play in modifying the natural proses of water carbon or nitrogen cycle
Answer:
-help to store water in the soil (by increasing infiltration) rather than evaporating (enabling the plants survive long periods of drought)
-mix inorganic and organic compounds in the soil (and thus it can better resist the process of erosion)
-termite’s feces help to prevent erosion
Explanation:
Decomposers break down complex organic matter into basic compounds containing nitrogen, phosphorus, and calcium, generating water (H2O) and carbon dioxide (CO2) during this process. Termites are critical in an ecosystem because they are decomposers, i.e., they are recyclers that break down organic material into nutrient-rich soil. For example, termites digest the cellulose from dead plants (due to the presence of specific bacteria in their digestive tract), thus allowing the carbon cycle.

What would be the expected result if a competitive, nonhydrolyzable analog of ATP were applied to the cytoplasmic side of a plasma membrane that contained a large concentration of the Na+/K+ pump? What would be the expected result if a competitive, nonhydrolyzable analog of ATP were applied to the cytoplasmic side of a plasma membrane that contained a large concentration of the Na+/K+ pump? The cell would accumulate Na+, but there would be no effect on K+. The cell would accumulate K+, but there would be no effect on Na+. The cell interior would experience higher than normal Na+ concentrations and lower than normal K+ concentrations. Both Na+ and K+ would accumulate outside of the cell.
Answer:
The cell interior would experience higher than normal Na+ concentrations and lower than normal K+ concentrations.
Explanation:
The Na/⁺K⁺ pump is an ATPase pump which is responsible for maintaining low Na⁺ and high K⁺ concentrations within the cytoplasm while maintaining high Na⁺ and low K⁺ concentrations in the extracellular fluid.
Since these two ions are moved against their concentration gradient, ATP hydrolysis is required to provide the energy for this process. This is done by moving in two K⁺ ions inside while moving three Na⁺ ions outside the cell for every molecule of ATP hydrolysed to ADP and Pi.
If a competitive non-hydrolyzable analog of ATP is applied on the cytoplasmic side of a plasma membrane that contained a large concentration of the Na/⁺K⁺ pump, it will act by inhibiting the action of the Na/⁺K⁺ pump. This will result in an accumulation of Na⁺ ions inside the cell and lower than normal K⁺ ions concentration.

Different cell types can react differently to epinephrine in the human body. Choose two cell types in the human body and briefly describe the cellular effect that occurs in the presence of epinephrine.
Answer:
I haven't really learned about cell types but I did find this information
Explanation:
How can epinephrine have different effects on different cells? Different cells have different receptors that bind epinephrine. Different cells activate different enzymes as a result of epinephrine binding.
epinephrine induces increased vascular smooth muscle contraction, pupillary dilator muscle contraction, and intestinal sphincter muscle contraction. Other significant effects include increased heart rate, myocardial contractility, and renin release

Explanation:a
byun walked 15 blocks in 25 minutes what was his average speed
Answer:
[tex]\frac{3}{5}[/tex]blocks/minutes
Explanation:
Given parameters:
Number of blocks walked = 15blocks
Time taken for the walk = 25minutes
Unknown:
Average speed = ?
Solution:
In this scenario, the average speed is the rate of walking the blocks per unit of time;
Average speed = [tex]\frac{number of blocks}{time}[/tex]
Input the parameters and solve;
Average speed = [tex]\frac{15}{25}[/tex]blocks/minutes
Average speed = [tex]\frac{3}{5}[/tex]blocks/minutes

Matter and energy can never bee created or destroyed. Explain how photosynthesis and cellular respiration demonstrate this law of nature.
They're linked. Cellular respiration uses oxygen and glucose from photosynthesis. Photosynthesis uses carbon dioxide, water, and energy from cellular respiration. Energy is transferred to other processes, not created or lost.
What is law of conservation of matter and energy?According to the law of conservation of mass or principle of mass conservation, any system that is closed to all exchanges of matter and energy must have a constant mass over time since the system's mass cannot vary and neither add nor subtract quantity.
Photosynthesis and cellular respiration are connected. Oxygen and glucose are obtained through photosynthesis and used in the process of cellular respiration. Carbon dioxide, water, and the energy released during cellular respiration are the three primary components of photosynthesis. Energy is not created nor destroyed; rather, it is transferred to other processes.
