2. Discuss four types of evidence that support the theory of evolution.
HELP PLZ!!!
Evidences that support the theory of evolution;
1. COMPARATIVE ANATOMY;
This is done to compare the anatomy structures of organisms to check the adaptive changes they have undergone through time. The similarities and differences of different body structures of different organisms are checked.
Through, homologous structures where structures are similar in organisms that share the same ancestor. Example, wings of bat and wings of bird.
Through, analogous structures where structures are similar in function in different organisms. Example, fore limbs of man and monkey which are used for grabbing.
2. COMPARATIVE EMBRYOLOGY;
This is done to check embryo development in different organisms throughout time and check the similarities and differences in their development. Example, embryo of man and fish both have gills at embryo stage and in fish they develop but in man they disappear before birth.
3. FOSSILS RECORDS;
The study of fossils shows the evidence of evolution as scientists study the fossils and the development of organisms present, it displays the changes that have occured throughout the years and how other organisms share ancestors and have evolved.
4. MOLECULAR BIOLOGY;
The study of the genes of organisms to check the relationship between organisms and the changes they have undergone through time. Molecular similarities show shared ancestry of organisms. Example, human and chimpanzee share a common ancestor because they both have a gene that encodes insulin hormone.

6. explain the relationship between enzymatic active sites & the
catalytic cycle of an enzyme
Answer: To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates. ... The part of the enzyme where the substrate binds is called the active site (since that's where the catalytic “action” happens). A substrate enters the active site of the enzyme.

Frederick Griffith made a scientific discovery in 1928. Which best describes
the knowledge about genetics before 1928?
Answer:
Frederick Griffith's discovery on the theory of genetics is credited to his experiment on mice. He subjected them to different strains of pneumonia bacteria. He concluded that there is an unidentified force that leads to the formation of different strains from what the mice were subjected to. This leads to the discovery of DNA, the carrier of traits. Scientist before did not know how the trait is passed on not until Griffith's experiment.

why are they assuming the large molecules will stay on their own side of the membrane?
Answer:
What is osmosis? Why are they assuming the large molecules will stay on their own side of the membrane? The membrane is semipermeable, so the membrane only allows some molecules through and not others. In this case, it doesn't allow the large molecules through.
Explanation:
Hope It Helps
It is assumed that the large molecules will stay on their own side of the cell membrane because the membrane is semipermeable which only allows the passage of some molecules in and out of the membrane.
What is a Cell membrane?A cell membrane may be defined as a type of biological membrane that significantly separates and protects the inner environment of all cells from the outside environment. It is semi-permeable in nature.
The cell membrane consists of a lipid bilayer that is semi-permeable. The cell membrane regulates the transport of materials entering and exiting the cell.
The ability of a molecule to travel across a membrane depends on its concentration, charge, and size. In general, molecules diffuse across membranes from areas of high concentration to low concentration. Cell membranes prevent charged molecules from entering the cell unless the cell maintains an electrical potential.

In some cases, people who test positive for genetic testing can receive preventive treatments. For example, people who test positive for the breast cancer genes BRCA1 and BRCA2 can have a preventive mastectomy (breast removal surgery) before they develop the disease. In other cases, no preventive treatments are available, but frequent monitoring can help detect a disease earlier, when it’s more easily treated.
What ethical or professional concerns does a health-care professional need to address when he or she has a patient who wants to prematurely treat a genetic disease? Do you think genetic testing should be part of normal preventive healthcare? Why or why not?
Answer:
yes
Explanation:
The obvious benefit of genetic testing is the chance to better understand of your risk for a certain disease. It can help ease uncertainty. Testing is not perfect, but it can often help you make decisions about your health.
Answer:
When it comes to treating genetic diseases, there are ethical and professional concerns that healthcare professionals need to address. For example, a patient who wants to undergo preventive treatment for a genetic disease may be putting themselves at risk unnecessarily, and a healthcare professional needs to weigh the potential benefits against the risks. Additionally, there may be financial and emotional costs associated with these treatments, and a healthcare professional needs to take these factors into account as well.
As for whether or not genetic testing should be part of normal preventive healthcare, there are arguments on both sides. On the one hand, genetic testing can help identify potential health risks before they become serious problems, allowing patients to take proactive steps to prevent or manage these issues. On the other hand, genetic testing can be expensive and may cause undue stress or anxiety for patients who receive unexpected results. Ultimately, the decision to include genetic testing in preventive healthcare should be made on a case-by-case basis, taking into account the individual patient's needs and circumstances.
Explanation:
In the field of healthcare, it is vital to acknowledge the ethical and professional dilemmas that arise when patients request early intervention for a genetic ailment. While preventive treatments can be effective in certain scenarios, healthcare providers must weigh the potential benefits against the risks and side effects of the treatment. Moreover, healthcare practitioners must consider the psychological impact of a positive genetic test result on their patients.
The question of whether genetic testing should be included in routine preventive healthcare is multifaceted. On one hand, genetic testing can provide valuable insight into a patient's susceptibility to certain diseases, thereby facilitating early detection and intervention. However, genetic testing can also pose ethical concerns regarding privacy and possible discrimination based on genetic data.
In the end, the decision to pursue genetic testing as a means of preventive healthcare should be determined on a case-by-case basis, with careful consideration of the potential risks and benefits, as well as the individual values and beliefs of the patient.

the amount of water in each body compartment mainly is controlled by
Answer: Ion Concentration
The ion concentration in water molecules controls the amount of water in a compartment
The concentration of ions in a body of water determines the rate of diffusion and osmosis that occurs in a body of water contained within a body compartment. which has a direct impact on the amount of water that is held in any water body compartment.
Hence we can conclude that the ion concentration in water molecules controls the amount of water in a compartment.
