Answer:
Area
Explanation:
B.Living things can recycle elements within an ecosystem as long as decomposers are present.
C.Matter flows in a one-way direction with a 10% loss at each move up in trophic level.
D.Elements continuously cycle between the physical environment and living organisms.
Correct answer choice is:
D) Elements continuously cycle between the physical environment and living organisms.
Explanation:
Any nonliving matter that living things want is termed a nutrient. Carbon and nitrogen are parts of nutrients. Unlike energy, the object is converted into ecosystems. Decomposers deliver nutrients when they cut down dead organisms. When one organism eats a different organism, it takes all of its nutrients. Nutrients can also cycle out of an ecosystem. Falling leaves may be moved out of an ecosystem by a water. Decomposers cut down dead organisms into nutrients and carbon dioxide, which they respire into the air.
Answer:
In the lock-and-key model of enzyme action, the substrate fits into the active site of the enzyme. Enzyme catalyzes a chemical reaction which starts with the binding of the substrate with the active site (specific region) present in the surface of the enzyme.
Some changes occur in the distribution of electrons in the chemical bonds which are present on the substrate and cause the reaction to leads the formation of products by the binding of the substrate to the enzyme.
The product which is released from the enzyme surface to regenerate the enzyme for next reaction cycle. The active site has unique ability means only one or few enzymes can react with similar compounds.
In the lock and key theory, the enzyme is the lock and key is the substrate. Which means only correct size substrate can fit into the active site of the enzyme.
Answer:
Hydrotropism causes cells to grow longer on one side of the roots.
Explanation:
Answer: pressure changes
Weathering is a natural phenomena in which the rocks are broken down into small pieces or sediments. It is caused by weathering agents such as wind, water, chemical, pressure and temperature.
Pressure changes is the weathering agent which would cause rocks to be pushed to the earth's surface where they often crack or break. The pressure could be applied by the superficial rocks or any other denser object.
Question options:
A new scientific law would be established and proven by the findings. A new scientific theory would be established and proven by the findings. A current scientific law would be revised based on the new findings. A current scientific theory would be revised based on the new findings.
Answer:
A current scientific theory would be revised based on the new findings.
Explanation:
If new findings came about and challenged the current theory of natural selection so that Darwin's theory didn't look like it was true at all, the initial theory(darwin's theory of natural selection) would not be entirely discarded but revised according to these new findings and then form a sort of backbone to this new theory which would be based on findings of many independent researchers and not just one. Example: how some of Sigmund Freud's theories or Aristotle's may not be entirely valid today but still works as a fundamental for understanding other theories.
The answer is increased. Hope this helped.
In a population, when the birthrate becomes higher than the death rate, the population’s growth rate is increase.
A population is a group of individuals of the same species that live in a particular area or number of people living in the same area, for example, a city population means the number of people living in that city.
Population growth is the change in a population over time. It can be increasing or decreasing, depend on some factors. Four factors that affected the population:
The population's growth rate increase when the birth rate is higher than the death rate, or the emigration is lower than the immigration. When the death rate is higher than the birth rate or the emigration rate higher than immigration rate the population's growth is decreased. The population growth is a result of a combination of natural increase and migration flows.
