Answer:

By injecting a functioning copy of the gene mutated in Sam's DNA in the cells of his eyes. Then seeing any reactants damage the cells using a microscope.

Explanation:

The evidence that could you collect to confirm that the mutation identified in a patient's DNA causes symptoms of RP is a model organism that can be used to confirm the mutation.

Retinitis pigmentosa (RP) is a hereditary condition that results in cell loss and breakdown in the retina, which increases light sensitivity and causes tissue lines at the back of the eye.

The mutation is a disorder that is caused by the genetic modification of genes and chromosomes. This causes genetic disorders in the organism, and these defects may be lethal.

These diseases are hereditary, which mean they are transferred from parents to children and some genetic disease can be detected in the fetus of the mother.

Thus, a model organism, identified in Sam’s DNA, causes symptoms of RP.

Receptors in muscles provide the brain with information about body position and movement. The brain controls the contraction of skeletal muscle. The nervous system regulates the speed at which food moves through the digestive tract.

Changing only one variable at a time is a  rule for conducting a controlled

experiment.

Controlled experiment involves the use of dependent and independent

variables . Changes in the independent variable brings about a

corresponding change in the dependent variable which is then recorded.

It is however important to note that changing more than only one variable at

a time won't accurately determine if the changes in the results were as a

result of one cause. This is why only one variable has to be changed at a

time.

Answer:

CARBOHYDRATE DIGESTION AND ABSORPTION

For dietary carbohydrates to be utilized by the body, they must be converted during digestion to monosaccharides. In addition to starch, the other major dietary carbohydrates are the disaccharides lactose and sucrose, and the monosaccharide fructose. The monosaccharides produced by complete digestion of these dietary carbohydrates are glucose, galactose, and fructose.

The digestive process begins with salivary amylase, which randomly cleaves the α-1,4 linkages of starch. Although amylase digestion begins in the saliva, pancreatic α-amylase is more important to the complete digestion of starch (Fig. 19-1). Starch is degraded first to dextrins and then to a mixture of glucose, maltose, and isomaltose (containing the α-1,6 linkages that are not digested by amylase).

The major disaccharidases, located in the brush border of the intestinal lumen, are

•

Maltase—hydrolyzes maltose

•

Sucrase-isomaltase—hydrolyzes sucrose and isomaltose

•

Lactase—hydrolyzes lactose

Whenever lactose goes undigested, it is not absorbed and passes into the large intestine. Here lactose is acted on by the intestinal flora that ferment it, producing large quantities of CO2, hydrogen gas, methane, and organic acids; the last irritate the intestines, increasing intestinal motility. All these products have only one way out. Thus, the symptoms that characterize lactose intolerance are bloating and flatulence and, in extreme cases, a frothy diarrhea. Lactose intolerance is least common in Northern Europeans and their descendants and most common in descendants of Asian, African, and South American origin.

HISTOLOGY

Brush Border Dynamics

The unstirred brush border of the intestinal lumen consists of finger-like processes, known as microvilli, of the surface absorptive cells. Many enzymes associated with the process of digestion and absorption are located on the surface of these microvilli. This allows the products of digestion such as free fatty acids, amino acids, and monoglycerides to be absorbed by the cells rather than be swept into the lumen itself.

Genetic variation exists in a population. Some of the genetic variation results in different phenotypes. The phenotypes that enhance survival are called adaptations. So, the correct option is A.

Genetic variation among members of the same species is called genetic variation. This variation may be due to variations in gene expression, DNA sequence and epigenetic changes. Mutation, genetic recombination, and genetic drift are causes of genetic variation, which can be altered by environmental variables including exposure to chemicals or climate changes.

Genetic diversity is important because it gives natural selection a starting point to work from, helping organisms to adapt and change over time. There is genetic diversity within a population. Different phenotypes are the result of some genetic variation. Adaptations are traits that improve survival.

Therefore, the correct option is A.

Your question is incomplete, most probably the complete question is:

Natural selection, adaptations, genetic variation, and population evolution are all related in terms of changes in phenotypes over time. Evaluate which statement appropriately describes the relationship between the concepts of natural selection, adaptations, genetic variation, and population evolution and select the best choice.

1. Genetic variation exists in a population. Some of the genetic variation results in different phenotypes. The phenotypes that enhance survival are called adaptations. Individuals with well-adapted phenotypes are more likely to survive and reproduce, leading to population evolution over generations.

2. Adaptations exist in certain individuals in a population. The increase in adaptations causes an increase in genetic variation. The adaptations that enhance survival lead to larger populations, which further increases genetic variation. Individuals with well-adapted phenotypes are more Likely to survive and reproduce, leading to population evolution over generations.

3. Genetic variation is high in a population, but random events cause it to decrease. Populations with fewer individuals and lower genetic diversity are able to undergo natural selection when selective pressures are high. The increase in selective pressure causes an increase in adaptations that are better suited for survival This results in an evolutionary change of a population.

4. Selective pressures exist in nature and cause changes in a population. Populations with high selective pressures have higher rates of genetic change, leading to an increase in genetic variation, Increased genetic variation leads to some individuals having well-suited adaptations. The presence of these new adaptations is evidence that the population haschanged, or undergone evolution.

Austin who was securely attached in Mary Ainsworth's theory of mother-infant attachment likely showed confidence in his caregiver's ability to protect him.

Options to this question were not provided. However, it is worthy to note that Mary Ainsworth's theory of mother-infant attachment classifies the relationship that children have with their caregivers as; Secure, Resistant, and Avoidant.

The Securely attached children are distressed when their mother is absent, they avoid strangers when their mother is not around but become friendly to strangers when their mothers are present.

They are also happy when their mother is around.

Generally, these sorts of children are confident and exhibit high self-esteem. So, Austin must have displayed some of these qualities.
