What is the relationship between a DNA molecule and a chromosome?
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
Answer: A. DNA is tightly coiled chromosomes
Explanation:
Tortoises found on the Galapagos Islands can have varied phenotypes. One of the variations in the phenotypes is with regard to
their shells. They can have a domed shell with a hood above the head. The shells without domes lack the hood above the head,
such that the tortoise's neck is always pointing downward. A group of evolutionary biologists studied the tortoise population for
generations on these islands. The study coincided with a severe drought in the area that lasted many years. The data for the
changes in tortoise shell shape is shown here. Evaluate the data and select the statement that is best supported by this data.
Answer: B:The drought decreased the grass and vegetation on the ground, leaving only vegetation on shrubs and trees above the ground. Natural selection selected for the tortoises with the domed shells and hoods.

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.

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
When energy is transferred to or from a substance, it can change the molecules’ freedom of movement. True or False?
Answer:
True
Explanation:
When transfer energy, the substance's temperature changes which can change the molecules' freedom. For example, when water freezes the water molecules loose temperature and slow down, unlike in a gas where molecules are free and energetic.

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.

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.

Answer:
1. Base triplets code for a single amino acid
2. Amino acids are linked based on the genetic code.
3. Connecting amino acids form proteins
4. Proteins make up most enzymes which regulate cell processes,
Explanation:
Genes, which are found in DNA, holds the information needed for every life process in an organism. However, the information in this gene needs to be utilized via a process called GENE EXPRESSION. Gene expression involves two processes namely; transcription and translation.
In transcription, information on DNA is copied into an mRNA strand, which is then used to synthesize an amino acid sequence in the translation process. The amino acids are joined together in a peptide linkage to form PROTEIN, which is responsible for regulating the cellular processes that occur in our cells. In a nutshell, the process is summarized as follows:
- Base triplets code for a single amino acid e.g. AUG codes for methionine
- Amino acids are linked based on the genetic code
- Connecting amino acids form proteins
- Proteins make up most enzymes which regulate cell processes.

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. DOI: http://dx.dol.org/10.15585/mmwr.ss6507at. Read the article thoroughly, and then answer these questions about the agent of gonorrhea and its potential for antibiotic resistance. eBook erences
Select all of the characteristics below that apply to Neisseria gonorrhoeae. (NOTE: Please change all question marks to checkmarks for correct answers or empty boxes for incorrect answers.)
a. It is a virus.
b. It usually affects the urogenital system but may also affect the eyes.
c. It is a gram-positive bacterium.
d. It must be grown on selective and enriched media.
e. It is gram-negative bacterium.
f. It can cause asymptomatic infections.
g. It usually affects the nervous system.
h. It is a yeast.
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.

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.
