Answer and Explanation:
Lipids are non-polar molecules, so they do not interact preferentially with polar molecules but they can interact with each other. In a polar medium, such as water, the hydrocarbons in lipids aggregate each other, in order to minimize contact with surrounding polar molecules. The interaction between non-polar solutes with polar surroundings exclusion is called hydrophobic interaction.

List the four steps of mitosis in order. Describe what is happening during each phase.
Answer:
The four stages of mitosis are known as prophase, metaphase, anaphase, telophase. Additionally, we'll mention three other intermediary stages (interphase, prometaphase, and cytokinesis) that play a role in mitosis. During the four phases of mitosis, nuclear division occurs in order for one cell to split into two.

2. What can you infer from the fact that ants make up
20 percent of the mass of all land animals combined?
a. Ants are very heavy
b. Ants live for a long time
c. Ants thrive in locations all over the world
d. Ants breed faster than any other organism on earth
Ant breed faster than any other organism on earth, 20% of earth mass have land animals. Many ants are on the earth. Thus, option D is correct.
What are the major features of ants ?Ants belongs to Formicide family which is related to so called eusocial insects like bees and termites. It is appeared in the Cretaceous period that is more than 90 million years ago.
The diversity of ants is every where except Antarctica.
The body has three parts such as a head, a meso-some and metasoma or gaster.
Ants are mostly omnivorous but can be scavengers , predators or herbivores based on ecological context.
The reproduction in which young, queens fly during mating time, fertilize with male, this flight is called as nuptial flight.
Then queen lay eggs, then larvae emerge to become pupae, then adults such as workers, soldiers, males or other queens are produced.
Thus, option D is correct.

what do the arguments for and against the use of stem cells in medical research share?
Answer: Stem cell research can potentially help treat a range of medical problems. It could lead humanity closer to better treatment and possibly cure a number of diseases:
Parkinson’s Disease
Alzheimer’s Disease
Heart Diseases, Stroke and Diabetes (Type 1)
Birth Defects
Spinal Cord Injuries
Replace or Repair Damaged Organs
Reduced Risk of Transplantation (You could possibly get a copy of your own heart in a heart-transplantation in the future
Stem cells may play a major role in cancer
Better treatment of these diseases could also give significant social benefits for individuals and economic gains for society
Cons
"We should not mess with human life."
"Humans should not be trying to play God"
Some argue that stem cell research in the far future can lead to knowledge on how to clone humans. It is hard to say whether this is true, but we have seen devastating consequences of other research-programs, even with good intentions, such as nuclear research.
Stem cells are cells, which have the ability to transform into many different types of cells. The stems cells have the potential to specialize in any type.
The stem cells are extensively used for research, curing diseases, and especially in developing prosthetics. The stems cells provide new cells for the growth and development of the replaced and damaged cells.
The arguments for and against the use of stem cells are:
Arguments for the use of stem cells in medical research are:
1. The stem cells enhance the growth and development of healthy skin tissue.
2. The cells can be used to enhance the production of collagen.
3. The study of stem cells helps in understanding the causes of disease.
Arguments against the use of stem cells in medical research are:
1. The use of stem cells for research harms human life and dignity.
2. People believe that killing blastocysts or stem cells is equal to taking a human life.
3. However, the transplant of stem cells can be rejected by the patient's body, therefore, can cost the life of the patient.
Therefore, the use of stem cells for research can be fruitful or disadvantageous.

What are the answers for questions 4 and 5?
Answer:
4. D (enzymes 1 and 3 works equally well in an acidic and alkaline environment respectively)
5. C. 2; 7; 9.5
Explanation:
The image attached to this question shows a graphical representation of the pH ranges for three enzymes. According to the image;
- Enzyme 1 reached its peak reaction rate at pH 2 (acidic)
- Enzyme 2 reached its peak reaction rate at pH 7 (neutral)
- Enzyme 3 reached its peak reaction rate at pH 9.5 (basic)
This result means that enzymes 1, 2 and 3 will work well and effectively at an acidic, neutral and alkaline environment respectively. Likewise, the optimal pH level for enzymes 1, 2 and 3 are 2; 7; and 9.5 respectively.
