To determine the probability of the offspring having red-green color blindness from the Punnett square, we need to know the genotypes of the parents. The probability of having a female offspring with normal color vision (X^RX^R genotype) is 0%, and the probability of having a male offspring with normal color vision (X^RY genotype) is also 0%.
What is Red-green color blindness?
Red-green color blindness is a sex-linked recessive trait that is carried on the X chromosome. Females have two X chromosomes, while males have one X and one Y chromosome. A female who carries one normal X chromosome and one X chromosome with the color blindness allele is said to be a carrier.
A male who inherits the color blindness allele on his X chromosome will have the condition because he does not have a second X chromosome to compensate for the mutation.
Assuming that the mother is a carrier (X^RX^r) and the father is not color blind (X^RY), the Punnett square would look like this:
| X^R | X^r
--|------|-----
X^R| X^RX^R| X^RX^r
--|------|-----
X^Y| X^RY | X^rY
The possible genotypes of the offspring are X^RX^R, X^RX^r, X^RY, and X^rY.
X^RX^R: Female with normal color vision.
X^RX^r: Female carrier with normal color vision.
X^RY: Male with normal color vision.
X^rY: Male with red-green color blindness.
From the Punnett square, we can see that there is a 50% chance that the offspring will inherit the normal X chromosome from the mother and a 50% chance that they will inherit the normal X chromosome from the father.
Therefore, the probability of having a male offspring with red-green color blindness (X^rY genotype) is 50%, and the probability of having a female carrier offspring (X^RX^r genotype) is also 50%.

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.

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.

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.

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.
