a friend believes that studying the genetics of dead organisms offers little benefit to modern day humans do you agree with this statement to use information from the article to support your argument.
Studying the genetic ancestry of humans can help explain why some people have a higher or lower risk of certain diseases. Finding the genes related to certain diseases will help fuel new drugs and therapies. For example, the article explains that people with six copies of CLPS genes seem to have a lower risk of diabetes
Explanation:
According to me, the process of studying the genetics of dead organisms offers significant benefits to modern-day humans.
What is Genetics?Genetics may be defined as the branch of biology that deals with the study of heredity and variations that are remarkably controlled by genes.
The genetics of dead organisms reveals the process and methodology of past organisms. It illustrates how the differences in present organisms lead to the process of evolution.
It compares the physiology, psychology, genomic sequencing, alterations in the genetic arrangements, etc. It also allows us to understand new facts and changes that fascinate evolutionary questions.
Apart from this, modern technology makes the study of dead organisms more effective and significant with numerous benefits like recombinant DNA technology, DNA analysis, isolation, etc.
Therefore, the process of studying the genetics of dead organisms offers significant benefits to modern-day humans.

What provides short term quick energy for the body?
Scientific Process , Describe its importance
Answer:
The scientific method attempts to minimize the influence of bias or prejudice in the experimenter. Even the best-intentioned scientists can't escape bias. It results from personal beliefs, as well as cultural beliefs, which means any human filters information based on his or her own experience. Unfortunately, this filtering process can cause a scientist to prefer one outcome over another. For someone trying to solve a problem around the house, succumbing to these kinds of biases is not such a big deal. But in the scientific community, where results have to be reviewed and duplicated, bias must be avoided at all costs.
That's the job of the scientific method. It provides an objective, standardized approach to conducting experiments and, in doing so, improves their results. By using a standardized approach in their investigations, scientists can feel confident that they will stick to the facts and limit the influence of personal, preconceived notions. Even with such a rigorous methodology in place, some scientists still make mistakes. For example, they can mistake a hypothesis for an explanation of a phenomenon without performing experiments. Or they can fail to accurately account for errors, such as measurement errors. Or they can ignore data that does not support the hypothesis.

A group of students is trying.to determine which detergent will best remove an oil stain. They stain five separate cloths with oil and.then wash each of.the cloths in a deficient detergent. They repeat each test two more times. Which step should be included in their investigation plan?
Answer: Place each oil stain on separate, but identical, pieces of cloth.
The group of students should have stained separate but identical pieces of cloth.
There are different factors that influence how easily a stain will come out of a material such as:
the type of material the detergent used the temperature of the waterAssuming the temperature is held constant and the type of detergent is being tested, the only thing other thing to control is the type of material.
The students used separate cloths instead of identical ones which meant that a significant variable was not controlled.
In conclusion, the students should use separate but identical pieces of cloth so that the type of material would not impart their experiment.

What is difference between Microtubules and Microflaments?
Microfilaments
Microfilaments are fine, thread-like protein fibers, 3-6 nm in diameter. They are composed predominantly of a contractile protein called actin, which is the most abundant cellular protein. Microfilaments' association with the protein myosin is responsible for muscle contraction. Microfilaments can also carry out cellular movements including gliding, contraction, and cytokinesis.
Microtubules
Microtubules are cylindrical tubes, 20-25 nm in diameter. They are composed of subunits of the protein tubulin--these subunits are termed alpha and beta. Microtubules act as a scaffold to determine cell shape, and provide a set of "tracks" for cell organelles and vesicles to move on. Microtubules also form the spindle fibers for separating chromosomes during mitosis. When arranged in geometric patterns inside flagella and cilia, they are used for locomotion.

6. Alex wanted to find out what toothpaste made teeth the cleanest. Everyday she brushed her teeth with a different product and then took a plaque test to see how much plaque was left. She used Crest, Colgate, Close-up, and water. a. Independent Variable (IV): ______________________________________________ b. Dependent Variable (DV): ______________________________________________ c. Control: _____________________________________________________________ d. Constants:__________________
Answer:
Independent variable: Different products of toothpaste
Dependent variable: Amount of plaque left in her teeth
Control group: Water
Constant: Same amount of time for product to have an effect
Explanation:
Independent variable is the variable that is subject to manipulation or change by the experimenter in order to effect a measurable response. The independent variable in this experiment is the DIFFERENT PRODUCTS OF TOOTHPASTE USED.
The dependent variable is the variable that is measured during the experiment. In this experiment, the dependent variable is the AMOUNT OF PLAQUE LEFT IN ALEX'S TEETH.
The control group in an experiment is the group that does not receive the treatment/independent variable. In this case, the usage of WATER is the control.
The constant is the variable kept the same for all the groups in the experiment. In the case, the Same amount of time for each product to have an effect on her teeth is the CONSTANT.
1. Was the restoration project effective? Explain why or why not, supporting your answer with information from your data tables and graphs. 2. Why was counting the number of species in the area important? In your answer, consider the effect a mangrove habitat has on biodiversity. 3. After five years, the average height of each mangrove species was also measured. Did this information help you better evaluate the success of the restoration project, or did it change your mind? Explain your reasoning.
Answer:
1- Yes the restoration was effective because the north beach seeds were replant and in 5 years there was almost 100% regrowth of mangroves. After five years, the average height of each mangrove species was also measured.
2- Yes the counting the number of species in the area was important because it helped figure out how much the storm damaged each beach and it showed how the animals were affected. The effect a mangrove habitat has on biodiversity is by giving animals a home, a place to sleep and shelter.
3- Yes, after five years, the average height of each mangrove species was also measured which helped realize that the restoration project was a success.
an organism has a haloed number of 20. what is the organism's diploid number?
Answer:
The organism's diploid number is 40.
Explanation:
Haloed means half and Diploid means double of half. So in this case if it's haloed is 20, 20*2=40. The diploid number is 40.

critically evaluate the role of human beings in perpetuating climate change
Answer:
Explanation:
Industrialization and use of combustible engines for daily life activities by humans has led to the production and release of a large amount of greenhouse gases (such as CO₂, N₂O, CH₄ and CFC) into the atmosphere-which prevents a large amount of heat produced from the earth moving to space.
The burning of fossil fuels by combustible engines (from cars, trains, power generating sets e.t.c) widely used by humans has led greatly to this climate change. Trees that help absolve a large amount of the most abundant man-made greenhouse gas (CO₂) has not been massively planted around, which indirectly worsens the case of global warming. Trees would have absorbed/breath in the CO₂ while producing/breathing out O₂ that could help cushion the effects of global warming.
