When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between which two reservoirs of the carbon cycle? * A. Hydrosphere and biosphere B. Geosphere/lithosphere and atmosphere C. Atmosphere and biosphere D. Hydrosphere and geosphere/lithosphere
Answer:
B
Explanation:
When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between the Geosphere/lithosphere and the atmosphere.
Both the geosphere and the atmosphere represent important reservoirs of carbon. The digging-up of fossil fuels, otherwise known as exploration, is carried out in the geosphere or the lithosphere part of the earth. For example, crude oil is obtained deep from the ground. When the fuels are burned, they release carbon in the form of carbon dioxide into the atmosphere.
Hence, it can be concluded that carbon flows from the geosphere/lithosphere part of the earth to the atmospheric portion of the earth when fossil fuels are burned.
The correct option is B.
An archer shot a 0.06 kg arrow at a target the arrow accelerated at 5,000 m/s squared to reach a speed of 50.0 m/s as it is left the bow.During this acceleration what was the net force to the nearest newton?
Answer:
the net force to the nearest newton is 300 N
Explanation:
The computation of the net force to the nearest newton is shown below:
According to the newton second law of motion, the force is proportional directly to the change rate in momentum
So,
Resulted force = mass × acceleration
F = 0.06 kg × 5,000 m/s
= 300 N
Hence, the net force to the nearest newton is 300 N
Answer:
300 N

to intimidate rival males
O to run from a predator
Answer:
to intimidate his predators
Explanation:
The reasons would a male peacock spread his tail feathers to intimidate rival males. Thus, option E is correct.
What are the principles of natural selection?For natural selection to occur, four basic conditions are necessary:
Reproduction: organisms must reproduce to form new generations;Variability: there must be differences between individuals in the population;Heredity: Descendants must inherit characteristics from their parents.Natural selection has been known as the evolutionary mechanism proposed by Charles Darwin, who stated that the environment acts as a selector of characteristics, perpetuating the organisms best able to survive in a given place.
Genes that encode bright feathers give an advantage to the male peacocks over other males which do not have an equally bright assortment of feathers, increasing the individual's reproductive success. This results in the advantageous genes such as of bright feathers recurring over the generations and remaining a part of the gene pool.
Therefore, The reasons would a male peacock spread his tail feathers to intimidate rival males. Thus, option E is correct.

The statement "Cognition is studied indirectly" is true.
What is cognition?The mental action or process of obtaining psychological features and apprehension through self-satisfaction, experience, and the senses is the definition of cognition.
Cognitive psychologists are interested in the investigation of mental functions. This relates to the study of cognition, memory, learning, and problem-solving processes in people. Cognitive psychologists are interested in how people think or react psychologically to various situations.
On the other side, behavioral psychologists are interested in researching and observing behavior. It is additional research on the interactions between stimulants and outcomes.

Negative adaptations will become more common in a population is NOT a principle of evolution.
what is population ?A discrete accumulation identifiable characteristics such as people, animals with the objective of analysis and data collection is called a population.
A population consists of a same group of species who reside in a particular geographical place with their reproductive capacity to interbreed.

Sea otters regulate the presence of the sea urchins and thus, kelp is regulated for all organisms in the ecosystem. They help to keep enough kelp for other wildlife to feed on. Also, due to their ability to absorb carbon dioxide, the kelp aid in mitigating climatic change and also reduce erosion by reducing the speed of water at the coast.However, if there were too many sea urchins and no sea otter to regulate their production, the kelp would reduce and thus with no food in the ecosystem, it would collapse. As a result, the sea otter protects the kelp forests by checking the local sea urchin population. The sea otter is an example of a
Answer:
keystone species
Explanation:
The sea otter is an example of a keystone species in the scenario.
A keystone species is an organism that has a significant influence on the functioning of the entire ecosystem. Without this species, the ecosystem would either cease to exist in total or entirely different in structure. In other words, a keystone species is a fastener that holds the ecosystem together.
In this case, the sea otter indirectly regulates kelp for all organisms in the ecosystem by directly regulating the presence of sea urchins. Without kelps, several ecosystem functions such as climate change mitigation and erosion reduction would cease. Thus, the sea otter is playing a significant role as a keystone species.

Explanation:
Describe how an organism's genotypes codes for their phenotype. In your answer use the vocabulary terms: Phenotype, genotype, DNA, mRNA and protein. Please dont answer if you dont know it.
Answer:
The organism's genotype encodes their phenotype because the genotype corresponds to the characteristic that is determined by genes —formed by fragments of DNA— which are transcribed into mRNA to be translated into amino acid sequences in the synthesis of proteins, determining the morphological and functional characteristics of an organism, that is, its phenotype.
Explanation:
Genotype corresponds to the genetic information contained in the DNA, according to the sequence of nucleotides in its molecular structure. This genotype includes characteristics or polymorphisms that define the appearance and function of living beings.
Each DNA molecule constitutes a chromosome, formed by genes —DNA fragments— each of which determines specific characteristics.
When DNA is transcribed into mRNA, information is being sent that is necessary for the incorporation of amino acids into a protein that is being synthesized. The proteins, in turn, determine morphological and functional characteristics that constitute the phenotype of an individual.
