Answer:

Repeating an experiment more than once helps determine if the data was a fluke, or represents the normal case. It helps guard against jumping to conclusions without enough evidence. The number of repeats depends on many factors, including the spread of the data and the availability of resources.

Explanation:

From this cross of individuals that are heterozygous for a particular trait, the expected genotypic ratio of the F1 generation would be 1 AA: 2 Aa: 1 aa. The expected phenotypic ratio would be 3 individuals with the dominant trait (A_) to 1 individual with the recessive trait (aa).

Consider a cross between two individuals that are heterozygous for a particular trait.

Let A represent the dominant allele and a represent the recessive allele.

The genotypes of the parent generation (P generation) are Aa × Aa.

Punnett square for this cross:

       |  A   |   a   |

-------|------|------|

  A   |  AA  |   Aa  |

-------|------|------|

  a   |  Aa  |   aa  |

-------|------|------|

The Punnett square shows the possible combinations of alleles from the parent generation and predicts the genotypes and phenotypes of the offspring in the F1 generation.

Answer:

A. the switch is incomplete

Explanation:

The population's gene pool, the frequency of the B allele is 0.7 (or 70%) and the frequency of the b allele is 0.3 (or 30%).

To calculate the frequencies of the two alleles (B and b) in the population's gene pool, we can use the allele frequency formula. The allele frequency is the proportion of a specific allele within a population.

Given the genotypes BB = 30, Bb = 10, and bb = 10, we can determine the number of alleles in the population as follows:

Number of B alleles = 2 * (number of BB genotypes) + (number of Bb genotypes)

= 2 * 30 + 10

= 60 + 10

= 70

Number of b alleles = 2 * (number of bb genotypes) + (number of Bb genotypes)

= 2 * 10 + 10

= 20 + 10

= 30

Next, we can calculate the frequencies of the two alleles:

Frequency of B allele = (Number of B alleles) / (Total number of alleles)

= 70 / (70 + 30)

= 70 / 100

= 0.7

Frequency of b allele = (Number of b alleles) / (Total number of alleles)

= 30 / (70 + 30)

= 30 / 100

= 0.3

A survivorship curve reflects the relationship of survival rate with age. best curves the statement about survivorship.

Explanation:

heyy mate! hope this helped you!

A survivorship curve is a graph that shows the proportion of individuals in a population surviving at different age intervals. The correct statement is that survivorship curve describes the pattern of mortality in a population over time. The correct option is C.

Survivorship curve describes the pattern of mortality in a population over time. The survivorship curve is divided into three types, i.e., Type 1, Type 2, and Type 3. Survivorship curve type 1 represents a high survival rate throughout the lifespan of the population. It shows that most individuals survive until old age, and the mortality rate increases at the end of the lifespan.

Survivorship curve type 2 shows a relatively constant rate of mortality throughout the lifespan of the population. It indicates that the probability of survival remains the same throughout life.

Survivorship curve type 3 represents high mortality rates among young individuals in a population. It shows that most individuals die young, and only a few individuals survive to adulthood.

Therefore, the correct option is C.

The reaction that increases with catabolism is A, ΔG known as the free energy change.

Catabolism is a type of metabolic pathway that breaks down complex molecules into simpler molecules. This process releases energy, which can be used by the cell to perform other functions. The ΔG of a reaction is a measure of the free energy change that occurs during the reaction.

A negative ΔG indicates that the reaction is spontaneous and will occur without any input of energy. A positive ΔG indicates that the reaction is non-spontaneous and will not occur without an input of energy.

Explanation:

I don't think it is B because it lists mountains and lakes. Remember it is asking for biotic features. "The biotic factors of an ecosystem are the living components. Plants, animals, and all of the other organisms that live in an ecosystem are biotic factors."

Also, for the people who have this question on study island answer C is correct. I did B because I thought I was wrong but actually no, I was correct lol so B does not make any sense at all.

Your question is lacking the necessary answer options, so I will be adding them here:

A. standard deviation.

B. mean.

C. median.

D. correlation coefficient.

E. range.

So, given your question, the statistical measure which is most helpful for indicating the extent to  which high school grades predict college grades is: D. correlation coefficient.

A statistical measure can be defined as a numerical measurement of each value of a quantitative variable in a given population. Some of the commonly used statistical measure in science include the following;

Correlation coefficient can be defined as a statistical measure used for the measurement of the strength of the relationship between two (2) known variables and to represent their linear interdependence. Thus, the values of a correlation coefficient typically range from +1 (strong positive relationship) to -1 (strong negative relationship)

Hence, correlation coefficient is a statistical measure which is most helpful for indicating the extent to  which high school grades predict college grades because it would determine the strength of the relationship between them.

The process of cytokinesis, which is present in the cell cycle of other organim, is not present in Plasmodial slime mold's cell cycle. Cytokinesis in other organisms pulls newly-divided cells apart. In Plasmodial slime mold cell cycle, a coenocyte which is its resulting structure, is created by many nuclear divisions without the presence of cytokinesis. In other cases, the resulting structure is called a syncytium which is created by the fusion of cells after division.
