organism and the environment.
iii. Describe the contributions of photosynthesis and cellular respiration within and among
the four spheres. Discuss how carbon enters and leaves each of the four spheres and in
what forms.
Discuss the role of carbon storage in organisms
It only has to be one paragraph :)
Answer:
Plants reform the carbon into climatic carbon dioxide into carbon-containing organic compounds, such as sugars, fats, and proteins. Plants take in carbon dioxide by minute openings into their leaves, called stomata. They connect atmospheric carbon with water and produce organic compounds, utilizing energy trapped from sunlight in a method called photosynthesis. The by-product of photosynthesis is oxygen, which plants discharge into the atmosphere by the stomata.

Which of the following is a result of glycolysis?
a.Usage of oxygen as a strong oxidizer
b.Production of CO2
c.Conversion of FAD+ into FADH2
d.Splitting of a glucose molecule to form two G3P molecules
The main result of glycolysis is the splitting of a glucose molecule to form two G3P molecules. The Option D.
What is the main result of glycolysis?Glycolysis, the initial step in cellular respiration involves the breakdown of glucose. One of the key outcomes of glycolysis is the splitting of a glucose molecule into two molecules of glyceraldehyde-3-phosphate (G3P).
This process occurs in the cytoplasm and does not require oxygen. Glycolysis serves as the primary source of energy production in anaerobic conditions and plays a crucial role in both aerobic and anaerobic cellular respiration.

Examine the photographs of 16 species of anole lizards and sort them into as many groups as you want according to how they appear in the photographs. Explain how you grouped the lizards and your rationale for the various groupings. If you picked a body feature, speculate about the advantages or disadvantages of such a body feature in the environment that species occupies.
Answer:
On the basis of physical appearance.
Explanation:
We grouped the lizards into various groups on the basis of similarities and differences in the body structure, appearance and colour etc. The legs of anole lizards are small legs with pads on their feet for gripping surfaces which give them the advantage to climb up the trees while on the other hand, these small legs can't help in the survival on the land because they can't run too fast from their predators with these short legs so these legs has benefit in climbing the tree but disadvantage in running on the land.
which trait became more common over time why do you think this happened
Answer:
Whether an allele is dominant or not does not affect how common a trait is. Now of course traits can become more common over time. The changes just don’t have anything to do with whether the trait is dominant or not. If brown eyes gave an advantage, then it would start to become more common.
Explanation:
Traits that provide advantage to the organism become more common over time due to natural selection. Therefore, traits become common due to natural selection.
What is natural selection?Due to natural selection, traits that are desirable to an organism and help in its survival in an environment and allow them to reproduce successfully become common over time which help them to acclimatize more successfully.
For example, in a population of birds that feed on insects, some birds have longer beaks while some have shorter beaks. successful at obtaining food and surviving than birds with shorter beaks. Birds having longer beaks will feed on insects more easily than the birds with shorter beaks.
Longer-beaked birds with period of time will become more common in the population as they outcompete other birds for resources. Natural selection is influenced by various factors, such as genetic drift, gene flow, etc.
Therefore, desirable traits that are necessary for population will become more common over time due to natural selection.

Natural selection will only lead to evolution if it allows for an organism to ________.
a. possess advantageous traits.
b. compete for resources.
c. produce offspring.
d. all of the above.
Answer:
b
Explanation:
Natural selection will only lead to evolution if it allows for an organism to process traits, compete for resources and produce offspring. The correct option is d.
What is natural selection?Natural selection is indeed an evolutionary mechanism. Lifeforms which are better adapted to their surroundings are much more likely to flourish and pass on the genetic traits that helped them thrive. Species change and diverge as a result of this process.
Natural selection, Darwin proposed, is a framework for evolution in which genetic variants that help support life, reproduce and survive as well as become more prevalent in a population over time.
Natural selection will occur if three conditions are met, according to Darwin's theory. These conditions, which are outlined as,
Represent a struggle for survival.Exhibit variation.Undergo inheritance.These are the conditions that are said to be both necessary and sufficient for natural selection.
Natural selection will only result in evolution if an organism is able to process traits, compete for resources, and produce offspring.
Thus, the correct option is d.

calculate the kinetic energy of a dodgeball that has a mass of 2 kg and velocity of 4 m/s after being thrown
Answer:
Kinetic energy of dodgeball = 16 kg-m/s
Explanation:
Given:
Mass of dodgeball = 2 kg
Velocity of dodgeball = 4 m/s
Find:
Kinetic energy of dodgeball
Computation:
Kinetic energy = (1/2)(m)(v²)
Kinetic energy of dodgeball = (1/2)(Mass of dodgeball)(Velocity of dodgeball²)
Kinetic energy of dodgeball = (1/2)(2)(4²)
Kinetic energy of dodgeball = (1/2)(2)(16)
Kinetic energy of dodgeball = (32/2)
Kinetic energy of dodgeball = 16 kg-m/s
What influences other than humans affect genetic drift in populations?
Answer:
Every population experiences genetic drift, but small populations feel its effects more strongly. Genetic drift does not take into account an allele's adaptive value to a population, and it may result in loss of a beneficial allele or fixation (rise to 100% frequency) of a harmful allele in a population.

Gonorrhea and Antibiotic Resistance
The CDC has categorized several infectious agents based on the seriousness of their antibiotic resistance. Neisseria gonorrhoeae, the causative agent of gonorrhea, is one of several agents in the "Urgent Threat" category. Gonorrhea is also the second most common reportable disease in the United States. This makes gonorrhea a significant public health concern. Please locate this article through an online search engine: Kirkcaldy RD, Harvey A Papp JR. et al. Neisseria gonorrhoeae Antimicrobial Susceptibility Surveillance - The Gonococcal Isolate Surveillance Project, 27 Sites United States. 2014. MMWR Surveill Summ 2016;65/No SS-7):1-19.

Answer:
b. It usually affects the urogenital system but may also affect the eyes.
e. It is gram-negative bacterium.
d. It must be grown on selective and enriched media.
g. It usually affects the nervous system.
f. It can cause asymptomatic infections.
Explanation:
Neisseria gonorrhoeae is a gram negative bacteria known to cause the sexually transmitted infection called Gonorrhea. Gonorrhea is easily treated with antibiotics, as long as the patient seeks early care and discovers the disease early on, as it can be asymptomatic, especially in women. When left untreated, Neisseria gonorrhoeae can infect the nervous system, causing many problems and even leading to death.
Despite being known to attack the urogenital system, this bacteria can attack the eyes generating gonococcal conjunctivitis, which is also sexually transmitted.
Neisseria gonorrhoeae is a fastidious bacteria, which means that it only grows in specific, selective and enriched culture media.

fish and phytoplankton
plants and seaweed
seaweed and phytoplankton
coral and fish
Most living organisms need to take in oxygen to survive. It is responsible for plants and seaweed.
What are seaweeds?
Some seaweeds are microscopic, such as the phytoplankton that live suspended in the water column and provide the base for most marine food chains. Some are enormous, like the giant kelp that grow in abundant “forests” and tower like underwater redwoods from their roots at the bottom of the sea.
Most are medium-sized, come in colors of red, green, brown, and black, and randomly wash up on beaches and shorelines just about everywhere.
The vernacular “seaweed” is a bona-fide misnomer, because a weed is a plant that spreads so profusely it can harm the habitat where it takes hold.
Therefore, Most living organisms need to take in oxygen to survive. It is responsible for plants and seaweed.
