Net primary productivity is the amount of organic material that is available for transfer to the next trophic level after subtracting material used for respiration.
When a plant is eaten by a mouse, the mouse is consumed by a snake, and the snake is in turn consumed by a hawk. In this case, there will be less organic matter available.
Biomass change from lower to higher trophic levels by decreasing.
The incomplete burning of ethanol in gasoline is known to create black carbon and contribute to global warming.
There is less secondary consumers in an ecosystem than producers because there isn’t enough energy available to support more secondary consumers.
It should be noted that global warming brings about the increase in the temperature around the world.

Explanation:
In those parts of equatorial Africa where the malaria parasite is most common, the sickle-cell allele constitutes 20% of the b hemoglobin alleles in the human gene pool. In the United States, the parasite that causes malaria is not present, but African-Americans whose ancestors were from equatorial Africa are present. What should be happening to the sickle-cell allele in the United States, and what should be happening to it in equatorial Africa
Answer:
directional selection, stabilizing selection
Explanation:
Directional selection is a type of natural selection that favors one extreme phenotype over other phenotypes, thereby modifying allele frequency in the direction of the favored phenotype. This type of positive selection is the main cause of phenotypic diversification. In the USA, the environment created a selection pressure that favored individuals that don't have the defective sickle-cell allele, thereby reducing its frequency in this population. Stabilizing selection, also known as balancing selection, is a type of natural selection where the most common phenotype is selected in the population, thus predominating in future generations. In equatorial Africa, the defective sickle-cell allele is present in a high frequency because individuals that are heterozygous for this allele are less susceptible to malaria, and therefore balancing selection should maintain this allele in the African population.
When equipment malfunctions, a(n) _____ needs to be initiated.
A) Notification
B) Paper Work
C) Alarm
D) Work Order
Answer: Alarm
Explanation:
When equipment malfunctions, an alarm should be initiated to bring the malfunction to the attention of the relevant personnel.
This will ensure that whatever adverse effects the malfunction could have caused is mitigated and the machine can be attended to on time to prevent further damage.
Skim the headings and bold words in this section. Write four steps scientists might take to solve a problem.
Answer:
1) Create a hypothisis 2) Create experiment 3) collect data 4) write conclusion
The four steps that a scientist uses to solve a problem are creating hypothesis, experiment, data sorting and writing conclusion.
What are hypothesis?A hypothesis is an elaboration posited for a characteristic. The scientific technique requires that a hypothesis be testable in order for it to be considered a scientific hypothesis.
Scientists typically base scientific hypotheses on previous findings that cannot be adequately explained by existing scientific theories.
Any process that co-ordinate system data into some defined order to make it simpler to understand, analyze, or visualize is referred to as data sorting.
The conclusion is the final section of an academic essay. The conclusion should restate your response to the question and briefly summarize key points. It does not contain any new points or information.
A scientist solves a problem by developing a hypothesis, conducting an experiment, sorting data, and writing a conclusion.
Thus, by using these steps, scientist can come to an end for the problem.

what animal kingdoms were divided
Answer:
The scheme most often used currently divides all living organisms into five kingdoms: Monera (bacteria), Protista, Fungi, Plantae, and Animalia. This coexisted with a scheme dividing life into two main divisions: the Prokaryotae (bacteria, etc.) and the Eukaryotae (animals, plants, fungi, and protists).

A scientist is using a microscope to observe a type of
bacteria.
Which two structures would the scientist most likely see?PLEASE EXPLAIN WHY
A:nucleus and DNA
B:DNA and cell wall
C:cell wall and vacuole
D:vacuole and nucleus
Answer:
The two structures most likely to be observed by the scientist when looking at a type of bacteria under the microscope are cell wall and vacuole (option C).
Explanation:
Bacteria are prokaryotic organisms that lack a nucleus, most of the organelles, and whose DNA is dispersed in the cytoplasm. Some types of bacteria have a plasma membrane surrounded by a cell wall, and may be equipped with vacuoles to perform their functions.
It is very likely that two structures that are most likely to be differentiated when a type of bacteria is observed under the microscope are the cell wall and the vacuole, according with information above.
The other options are not correct because:
A and D. Bacteria lack a nucleus.
A and B. Bacterial DNA is dispersed in the cytoplasm and is very difficult to observe under the microscope.
Answer:
cell wall vacuole

Which of the following environmental parameters would be important to monitor in order to ensure sustainable logging?
A. The number of trees cut down versus number trees burned
B. The number of new trees planted to replace those removed
C. The number of trees needed to increase soil fertilization
D. The number of trees removed within a single species
Answer:
B. The number of new trees planted to replace those removed
Explanation:
Because to ensure that logging is sustainable, they have to sustain a certain ratio of trees cut down, to trees planted. D. The muber of trees removed within a single species could be right, but I think B is more right.
If you get this wrong you can blame it on me.

Which two structures are found at the outside of the cell?
Answer:
All cells share common components: (1) a plasma membrane, an outer covering that separates the cell's interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell.
If two hybrid tall pea plants are crossed what is the probability that the offspring will have the tall phenotype?
Answer:
There is a high probability that the Pea plant will have a High phenotype!
Explanation:
Because both "parent plants" are tall, this will cause the offspring to also be tall, this will be because it in it's genes or in other words DNA too be strong.

Which atom is involved in giving your heart energy to beat?
O carbon
O gold
O oxygen
O iron
Answer:
Oxygen
Explanation:
-How fast the heart beats depends on the body's need for oxygen-rich blood. At rest, the SA node causes your heart to beat about 50 to 100 times each minute. During activity or excitement, your body needs more oxygen-rich blood; the heart rate rises to well over 100 beats per minute.
-The heart, like any organ, requires blood for oxygen and other nutrients so it can do its work. The heart does not gather oxygen or nutrients from the blood flowing inside it. Instead, it receives blood from coronary arteries that eventually carry blood into the heart muscle.
