Read this paragraph from the passage “True or False: Can You Trust Your Memory?”:
“In my view, the similarities [in memory brain activity] outweigh the differences,” adds McDermott. “It’s really not possible at this point in time to reliably distinguish between real and false memories.”
Now read the paragraph below from “The Mind in the Machine.” As you read, think about how the information in the two paragraphs relate to one another. Which sentence from the text supports that artificial intelligence likely would have trouble distinguishing a true memory from a false memory?
a. The human brain has always been an important source of inspiration for computer scientists.
b. It’s the best example we have of an intelligence machine.
c. This approach roughly mimics the way the brain processes information.

In a cross Bb x Bb (B = Blue petals and b = pink petals), how many offspring will have the genotype Bb?
Answer:
2 offspring will have the genotype Bb.
Explanation:
Crossing the genotypes Bb and Bb results in 2, or 50% of the offspring having the genotype Bb. In the top right box, the B on the top and the B on the side make the BB genotype. In the top left box, B and b make the first Bb genotype. The lower right box crosses B and b to make the second Bb genotype. The last box in the bottom right crosses b and b, resulting in the genotype bb. So, after crossing the genotypes written on the top and side of the punnet square, 2 of the offspring will have the Bb genotype. (I got this by combining the letters outside the punnet square in the box where the row and column meet) .

Connect the importance between meiosis and the process of sexual reproduction. Is it possible to survive without your reproductive system? Explain.
Answer:
This can be made possible through reproductive cells undergoing meiosis since such process has specialized sex cells split and multiple after copulation. To answer the question if is it possible for a human to survive without a reproductive system, the answer is yes.

Answer:
Image result for Explain how cells are related to living things.
Cells are the basic building blocks of living things. The human body is composed of trillions of cells, all with their own specialised function. Cells are the basic structures of all living organisms. Cells provide structure for the body, take in nutrients from food and carry out important functions.
Explanation:
Which of the following are factors that limit enzyme activity?
denaturation
increase in substrate
optimal temperature
increase in number of enzymes
According to the research, increase in substrate and temperature are factors that limit enzyme activity.
What are enzymes?It is a protein that catalyzes the biochemical reactions of metabolism and acts on molecules known as substrates.
The way that the enzyme has to carry out its catalytic activity will be in the first place to bind with the substrate, this is limited by different factors such as the concentration of the substrate and the temperature.
Therefore, we can conclude that according to the research, increase in substrate and temperature are factors that limit enzyme activity.

How does the DNA sequence in a normal hemoglobin gene compare to a sickle cell hemoglobin gene?
ASAP
Answer:A person with normal hemoglobin has inherited one allele for normal hemoglobin from each parent and so has the genotype Hb A/Hb A. In contrast, a person who has sickle disease has inherited one sickle-cell allele from each parent and has the genotype Hb S/Hb S.
Explanation:
The DNA sequence in a normal hemoglobin gene is different from the hemoglobin gene of sickle cell due to a change in nucleotide base from A to T.
What is Sickle cell anemia?Sickle cell anemia is a group of disorders which cause the red blood cells (RBCs) to become misshapen and break down. It is an inherited group of disorders, in which the red blood cells contort into a sickle shaped cell. The cells die early due to this disorder, leaving a shortage of healthy red blood cells in the blood and can block the blood flow causing pain and crisis.
Symptoms of sickle cell anemia include infections, pain and fatigue.
Genetic studies have shown that the base sequence in the normal hemoglobin (HbA) and the sickle cell hemoglobin (HbS) differs at only a single nucleotide position including a change from an A to a T nucleotide base. This change in nucleotide to one codon results in a single amino acid change in the hemoglobin.

How does the electron transport chain deal with the electrons removed from sugar molecules?
Answer:
Explanation:
The electron transport chain is the portion of aerobic respiration that uses free oxygen as the final electron acceptor of the electrons removed from the intermediate compounds in glucose catabolism. The electron transport chain is composed of four large, multiprotein complexes embedded in the inner mitochondrial membrane and two small diffusible electron carriers shuttling electrons between them.
The electrons passing through the electron transport chain gradually lose energy, High-energy electrons donated to the chain by either NADH or FADH2 complete the chain, as low-energy electrons reduce oxygen molecules and form water.
These same molecules can serve as energy sources for the glucose pathways.

Describe the treatment goals for dialysis.
Answer:
The main goals are to keep your body in balance and keeping a safe level of certain chemicals in your blood.
Explanation:
Keeping your body in balance by removing waste, extra water, and salt to prevent those things from building up in your body. The certain chemicals are: potassium, sodium, and bicarbonate.
In dialysis, the main goals are to keep your body in balance and keeping a safe level of certain chemicals in your blood.
What do you mean by dialysis?Dialysis is a procedure to remove waste products and excess fluid from the blood when the kidneys stop working properly. It often involves diverting blood to a machine to be cleaned.
Average life expectancy on dialysis is 5-10 years, however, many patients have lived well on dialysis for 20 or even 30 years. Talk to your healthcare team about how to take care of yourself and stay healthy on dialysis.
High blood pressure and diabetes are the two most common causes of kidney failure. They can also become damaged from physical injury, diseases, or other disorders.
