Answer:
Charles Darwin had a theory that states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.
The theory of natural selection was proposed by Charles Darwin. Darwin postulated that species could change over time.
What is the theory of natural selection?The adaption by organism according to the surrounding environment is natural selection. It drives evolution.
Individuals in a population vary naturally. It means they are all different in some ways.
This variation means that some individuals have traits that suit better to the environment as compared than others.
This causes the species to change over time.
Thus, the process by which these changes take place is natural selection.

What types of mutations are the most harmful
Answer:
Frameshift mutations
Explanation:
Frameshift mutations are generally much more serious and often more deadly than point mutations. Even though only a single nitrogen base is affected, as with point mutations, in this instance, the single base is either completely deleted or an extra one is inserted into the middle of the DNA sequence.

Cystic Fibrosis is a genetic disease of the lungs caused by a recessive allele. A man with Cystic Fibrosis marries a woman who does not have Cystic Fibrosis, but her father had the disease. What is the probability of the couple having a child that has Cystic Fibrosis?
Answer:
There is no chance of child with the disease
Explanation:
As cystic fibrosis is a recessive disease homogeneous condition is required in child to have the disease . Since the mother is not suffering from the disease & there is no history in her family so she does not have the gene for cystic fibrosis

A track and field coach is trying to decide what beverage is the best pre-training beverage for athletes to drink before a daily training session. The coach has chosen three beverages: a soda, a Gatorade, and water for the athletes to drink before training. The coach will then collect data on their performance during the period of time while training.
Afterward, the coach will track the performance of the athletes over an eight week period to see how their performance has changed.
What is the best Hypothesis for the experiment above? Explain why that is the best Hypothesis.
Answer:
The correct answer is - "which beverage would help athletes the best if he takes it before a daily training session".
Explanation:
The coach is trying to decide which beverage is going to help best for the athletes before their training session. He tried soda, water, and Gatorade and compare the data he gets after his experiment.
According to his experiment, he wanted to find the best beverage that will help athletes best. For this, the best hypothesis would be "which beverage would help athletes the best if he takes it before a daily training session", as it provides the real idea of the experiment.

The location for the SI gene is 3q26.1. What does this information tell you?
The SI gene provides instructions for producing the enzyme sucrase-isomaltase
Annotation 3q26.1. indicates a specific localization of a gene on chromosome number 3.
The localization of a gene in a chromosome is indicated by a specific pattern of bands generated by different cytogenetic staining techniques.The first number/letter used in this code indicates the chromosome (in this case, 3 indicates chromosome number 3).The letter q represents the long arm of the chromosome, whereas the shorter arm is referred to as p (in this case, 3q)The following numbers represent the position of the gene on the chromosome arm, which is evidenced by specific patterns and staining techniques.In conclusion, annotation 3q26.1. indicates a specific localization of a gene on a chromosome.

Anthropologists have been studying the role of soybean curd andrelated products in the culture of Hong Kong. The researchers interviewpeople about how frequently they eat soybean products, where they eatthem (at home or in restaurants), and during what time of day they eatthem. The researchers also ask people about how they preparesoybean products, where they obtain soybean products, and any beliefsthey might have about soybean products (such as their nutritionalvalue). The data are used to assess the role of soybean products in theculture. The researchers are also considering how their findings relateto global soybean consumption patterns.
1. What is the primary field of anthropology addressed in this research?a. Linguistic anthropologyb. Archaeologyc. Biological anthropologyd. Cultural anthropology2. Which field of anthropology (other than the one you indicated above) is most related to this research?a. Biological Anthropologyb. Archaeologyc. Linguistic Anthropologyd. Cultural Anthropologye. All fields of Anthropology are related to this topic3. How might this research contribute to a comparative anthropological approach?a. This research could be used to compare quinoa consumption in other parts of the world.b. This research could be used to compare biological adaptations across Bolivia.c. This research could be used to compare quinoa consumption in other primate species.d. This research could be used to compare quinoa DNA to other plants.
Answer:
1.) Cultural Anthropology
2.) Biological Anthropology
3.) The research could be used to compare quinoa consumption in other parts of the world.
Explanation:
Anthropology is a scientific field that studies humans. It studies humans all over the world with respect to their behaviors and cultures in both past and present eras. Anthropology is divided into four major types: Cultural, Biological, Linguistic and archaeological.
1.) Because this research is towards the role of soybean and related products in Hing Kong, we can confidently say that it falls under the cultural aspect of anthropology which focuses on the study of differences in cultures among humans.
2.) Considering the fact that the research deals with a biological product (soybean) that has effects on humans, then biological anthropology is the most closely related field.
3.) The researchers intend to relate their findings from this research to global soybean and other related products consumption pattern. Therefore, this research could be used to compare quinoa consumption in other parts of the world.

What is poisonous enough to kill 100,000 turkeys? That’s the question asked by scientists who studied a mass die-off of turkeys in Great Britain. It turned out that all the turkeys had eaten peanuts from Brazil. A fungus was growing on the peanuts. The fungus produced a dangerous poison called aflatoxin. Aflatoxins cause stomach pain, lung failure, cancer, and death in people and animals.
Farmers make a great effort to prevent fungi from growing on their stored crops. In a pile of grain or nuts, fungi have plenty of food and living space. The best way for farmers to prevent fungi from growing is to make sure there is not enough for fungi to survive and grow.

Why is DNA locked in the nucleus of the cell?
Answer:
Inside the nucleus lies the blueprint that dictates everything a cell will do and all of the products it will make. This information is stored within DNA. The nucleus sends “commands” to the cell via molecular messengers that translate the information from DNA.
Explanation:
Answer:
In organisms called eukaryotes, DNA is found inside a special area of the cell called the nucleus. Because the cell is very small, and because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged. ... Researchers refer to DNA found in the cell's nucleus as nuclear DNA.

Eukaryotes have more complex modes of control, including the packing of chromosomes,____(which can produces several mRNAs from a single gene), and the control of translation. An understanding of gene regulation mechanisms has led to several interesting and important applications. For example, the loss of gene regulation can result in cancer, or out-of-control cell growth. And___can produce new live individuals, while___can produce potentially therapeutic stem cells.
Answer:
All organisms must regulate gene expression by turning genes on and off different cells at different times. In prokaryotic cells, related genes may be organized into operons , which can be turned on and off as a single unit. Eukaryotes have more complex modes of control, including the packing of chromosomes, RNA slicing (which can produces several mRNAs from a single gene), and the control of translation.
An understanding of gene regulation mechanisms has led to several interesting and important applications. For example, the loss of gene regulation can result in cancer, or out-of-control cell growth.
