Which of the following is not a step in the process of natural selection
A. Individuals who have favorable traits survive and reproduce more than those individuals lacking such traits.
B. Members of a population possess heritable variations.
C. People select which individuals breed and which ones do not.
D. Over multiple generations of reproducing, a larger proportion of the population will have those favorable traits and thus adaptation has occurred.
F. The population produces more offspring than the environment can support.
Answer:
A step that is not part of natural selection is people select which individuals breed and which ones do not.
Explanation:
Natural selection is a process in which favorable or unfavorable environmental conditions determine the evolution of species, producing differences in their genotype over a long period of time.
As its name indicates, it is a natural selection, in which no intervention by people is contemplated, so that people cannot determine which individuals breed.
Natural selection implies that the characteristics on which the environment influences are inheritable, that there is genetic variability in the population and that the variability of these characteristics implies the ease of reproduction and survival capacity.
The other options do form part of natural selection, since they are based on the three premises of this process:
Inheritable characteristics. Genetic variability. The variability of characteristics influences reproduction and survival.What factors should be taken into consideration when determining what raw materials to purchase? PLEASE HELP ME

Various cultures designate racial categories differently, and they often base these categories on very different traits. For example, some cultures use nose shape as one of the defining traits for a racial group. Other cultures do not use nose shape in defining racial groups, but use hair color instead. Conduct a survey in person on your campus, via social media accounts online, or among your friends and family. Ask at least 20 people what five traits they think are most important when distinguishing racial groups. Document the responses, and then review the data. Did every person use the same traits? What do differences in racial classification such as these suggest about the universality of race and racial groupings?
Answer:
In the clarification segment below, the definition of the query has been mentioned.
Explanation:
This shows that perhaps the distinctions between individuals living in a culture or geographical region are often based on ethnicity and ethnic groupings. A single population belonging to a specific geographical region has been shown to possess many characteristics, including hair texture, individual capacity for heat resistance, and food taste. Throughout certain races or ethnic groups, these similar traits bring them together. The young government corresponding to a certain race is often asked to follow the custom adopted by those belonging to a certain particular demographic. It is assumed that persons belonging to that same race follow these rituals mostly to solve difficulties they have experienced personally due to errors perpetrated by certain ancestors.Suppose that you began a one-year study of tuberculosis (TB) in St. Petersburg on January 1st, 2018. You enrolled 200 residents in your study and checked on their TB status on a monthly basis. At the start of your study on January 1st, you screened all 200 residents. Upon screening, you found that 10 of the healthy residents were immigrants who were vaccinated for TB and so were not at risk. Another 10 residents already had existing cases of TB on January 1st. On February 1st, two residents developed TB. On April 1st, three more residents developed TB. On July 1st, three of the residents who had existing TB on January 1st died from their disease. The study ended on December 31, 2018. Assume that once a person gets TB, they have it for the duration of the study, and assume that all remaining residents stayed healthy and were not lost to follow-up.
What was the prevalence of TB in the screened community on January 1st?
Answer: 5%
Explanation:
The Prevalence rate is the term used to describe the percentage of a population that have contacted the disease being tested for. It is usually done over a certain period or a certain time.
The prevalence of TB in the screened community on January 1st therefore is;
= Number of infected/ No. of Tested residents
= 10/200
= 5%

Which complementary DNA strand pairs correctly with the strand above?
A. 5’ CTAGCTAG 3’
B. 5’ GATCGATC 3’
C. 5’ CUAGCUAG 3’
D. 5’ CATCGATC 3’
Each base pair forms a "rung of the DNA ladder" by joining two complementary DNA nucleotide bases. Two linked strands of DNA form a double helix, which is a structure that resembles a twisted ladder.
What is complementary base pairing in DNA molecule?Because they are complementary base pairs, adenine binds to thymine while guanine attaches to cytosine. The complimentary bases may unite to form a bond.
This aids in holding the DNA molecule's two antiparallel strands together to form the helix. The complimentary base pairing rule refers to this.
Cytosine pairs with guanine, while adenine pairs with thymine. The two strands are so complimentary to one another.
For instance, a complementary DNA strand will have the nucleotide sequence 5' CTAGCTAG 3' for a DNA strand with the nucleotide sequence 3' GATCGATC 5'.
Therefore, According to this rule, nucleotides A and T and bases G and C are always equally abundant in DNA.

Photosynthesis/CR definition
Answer:
Photosynthesis is the process in which green plants and some other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Cellular Respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.

Why do some dominant traits have two different types of alleles?
Answer:
you inherit 2 alleles for each genes. one comes from your biological mom and the other comes from you biological father. if the alleles are identical like when both your parents have brown eyes and that it will cause you to have brown eye color. some alleles are dominant while the rest are recessive. the dominant trait is more stronger than recessive trait. It is a strictly relative effect between two alleles of a given gene of any function; one allele can be dominant over a second allele of the same gene, recessive to a third and co-dominant with a fourth. Additionally, one allele may be dominant for one trait but not others.

One type can differentiate into any cell, while another can only become specific cells. Select the answer that places the three types in the correct order, from widest range of differentiation to least able to differentiate (specific). (1 point)
A. totipotent, multipotent, pluripotent
B. pluripotent, totipotent, multipotent
C. totipotent, pluripotent, multipotent
D. pluripotent, multipotent, totipotent
Answer:
C
Explanation:
Totipotent can differentiate into any cell type-Pluripotent into less, and Multipotent being the most specialized.
The types of stems cells in the correct order, from widest range of differentiation to least able to differentiate will be C. totipotent, pluripotent, multipotent.
Totipotent simply means a single, immature cell that can give rise to a new organism. Pluripotent simply means substances that can be able to develop into different stem cells.
Lastly, the multipotent stem cells are the stem cells that can self-renew as they divide and then develop into multiple specialized cell types.
Therefore, the correct option is totipotent, pluripotent, and multipotent.
