Although bacteria and other single-celled organisms can produce genetically identical offspring. they sometimes still exchange DNA be passing it from bacteria to bacteria. What might be the advantage of exchanging DNA in this way?
p
Answer:
Bacteria, like all living organisms, have evolved at least one autonomous mechanism, conjugation, for exchanging portions of genetic materials between two related cells. The ecological benefits of conjugation include the expansion of metabolic versatility and resistance to hazardous environmental conditions.

How does carbon enter the biotic components of the carbon cycle?
A) through the process of respiration
B)through the process of photosynthesis
C)through the combustion of fossil fuels
D) through decomposition of dead organisms
In the carbon cycle, plants take CO2 from the atmosphere and carry out photosynthesis by which they incorporate carbon into the biotic components of organic compounds.
What is the carbon cycle?It is a biogeochemical cycle that starts with carbon dioxide in the atmosphere, which is adsorbed together with the sun's energy in the photosynthesis process of plants.
Characteristics of the carbon cycleDuring the day, plants use the Sun's energy to convert CO2 from the atmosphere plus water into carbohydrates and oxygen, this process is photosynthesis.Therefore, we can conclude that the carbon cycle is a cycle that flows through the terrestrial ecosystem, through the photosynthesis of plants, by animals or decomposing organisms, and the oceans.

What can be used to measure primary productivity in an ecosystem?(1 point)
carbon dioxide consumption
water consumption
oxygen consumption
sugar consumption
Carbon dioxide consumption
Carbon dioxide consumption can be used to measure primary productivity in an ecosystem.
Primary productivity refers to the rate at which energy is converted to organic material by photosynthesis.Primary productivity can be calculated by analyzing the change in biomass of producer organisms.Primary productivity can also be calculated by analyzing the movement of carbon dioxide (consumption).
Primary productivity can also be estimated by analyzing the movement of carbon dioxide the movement of oxygen over time.
In conclusion, carbon dioxide consumption can be used to measure primary productivity in an ecosystem.

What is contained inside the nucleus of every cheek cell?.
The content of the nucleus of every cell is DNA
NucleusThe nucleus is an organelle present in all eukaryotic cells.
The organelle contains instructions for all cellular processes.
The instructions are stored as genes, which are coded for by sequences of deoxyribonucleic acids.
Thus, since the nucleus largely contains DNA, and other molecules such as proteins, the nucleus of every cheek cell would also contain DNA.

Natural selection results in adaptation, increasing in the individual's fitness. Option C. Features are adaptations that help individuals outcompete other individuals for food resources to increase survival and reproductive success.
What is natural selection?
Natural selection is an evolutive force.
It selects beneficial alleles in a population and increases their frequency.
It is the result of the phenotype-environment interaction which determines gene destiny in space and time.
Natural selection results in adaptation, meaning that it causes an increase in the aptitude phenotype.
Aptitude (or fitness) is reflected by the phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring.
In many cases adaptations, resulting from natural selection can be correlated to environmental factors or selective pressures applied by other organisms or habitats.
In the exposed example, the features are adaptations that help individuals outcompete other individuals for food resources to increase survival and reproductive success.
selective pressure ⇒ competition for resources
influence in fitness ⇒ increase survival and reproductive success.

Use the data to explain the changes in phenotypic frequency from generation 1 to 3.
Do you think this population is in Hardy-Weinberg equilibrium? Provide reasoning to support your claim.
The phenotypic frequency from generations 1 to 3 shows there are naturally more individuals with the dominant trait. Moreover, changes in frequency show this population does not have Hardy Weinberg equilibrium.
What are the changes in phenotypic frequency?Phenotypic frequency refers to how common a trait is in one population. In this case, the number of individuals with a recessive vs those with a dominant trait.
From the information provided in the chart, we can see in the first three generations there is a higher number of individuals with a dominant trait, which is genetically natural, and this occurs even as the population grows.
Is there Hardy Weinberg Equilibrium?Hardy Weinberg Equilibrium is a principle that establishes under normal conditions phenotypic frequency should be constant. This does not occur in this population because by generation 6 there is almost the same number of individuals with a dominant and a recessive trait, which shows phenotypic frequency is changing.

Can the effects of UV light on folate explain the full variation of human skin color that exists among human populations today? Explain your reasoning
Human skin colour is due to a pigment called melanin. The melanin pigment is present in outer layer of skin cells. UV light causes increase in production of melanin resulting in darker skin shade.
Why the human skin colour varies?UV radiation can cause photolysis of folate. This can lower the level of folate. If the level of melanin increase, it will stop the breakdown of folate. This will result in variation of colour in high intensive UV areas.
Thus, it can be concluded that increased UV radiation can cause variation in human skin colour.
